Walther, M., Jakobi, T., Watson, S. J. & Stevens, G. (2023)A systematic literature review about the consumers’ side of fake review detection – Which cues do consumers use to determine the veracity of online user reviews?
IN Computers in Human Behavior Reports, Vol. 10, Pages: 100278 doi:10.1016/j.chbr.2023.100278
[BibTeX] [Abstract] [Download PDF]Background Consumers rely heavily on online user reviews when shopping online and cybercriminals produce fake reviews to manipulate consumer opinion. Much prior research focuses on the automated detection of these fake reviews, which are far from perfect. Therefore, consumers must be able to detect fake reviews on their own. In this study we survey the research examining how consumers detect fake reviews online. Methods We conducted a systematic literature review over the research on fake review detection from the consumer-perspective. We included academic literature giving new empirical data. We provide a narrative synthesis comparing the theories, methods and outcomes used across studies to identify how consumers detect fake reviews online. Results We found only 15 articles that met our inclusion criteria. We classify the most often used cues identified into five categories which were (1) review characteristics (2) textual characteristics (3) reviewer characteristics (4) seller characteristics and (5) characteristics of the platform where the review is displayed. Discussion We find that theory is applied inconsistently across studies and that cues to deception are often identified in isolation without any unifying theoretical framework. Consequently, we discuss how such a theoretical framework could be developed.

Lawo, D., Neifer, T., Esau-Held, M. & Stevens, G. (2023)Digital Sovereignty: What it is and why it matters for HCI
Extended Abstracts of the 2023 CHI Conference on Human Factors in Computing Systems. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–7 doi:10.1145/3544549.3585834
[BibTeX] [Abstract] [Download PDF]In recent years, digital sovereignty has become a central term in digital policy discourses. Both authoritarian and democratic states use digital sovereignty as a base for their digital policy, although, the individual interpretation and resulting policy and power balance might be quite different. Given the importance of this term, the HCI community and the users as the core of our research would benefit from taking up the discussion by finding own definitions of human-centred digital sovereignty, contributing to policy discourses, and to strengthening the position of users under non-sovereign conditions. This paper aims to initiate and provoke such discourse within the community by (1) introducing the policy term to HCI and providing an overview of how it is used, (2) arguing for the relevancy of the term, and (3) proposing possible ways forward.

Liu, J., Wang, X., Tolmie, P. & Wulf, V. (2023)Articulation Work and the Management of Intersubjectivity Disjunctures in Offshored Production
IN Proceedings of the ACM on Human-Computer Interaction, Vol. 7, Pages: 25:1–25:34 doi:10.1145/3579458
[BibTeX] [Abstract] [Download PDF]Since the move away from integrated value chains in production in the 1980s, the outsourcing and offshoring of various aspects of manufacturing has become commonplace. This has led to global production and marketing relationships between enterprises in numerous different countries, a prominent axis being between Europe and Asia. This paper reports on a study of one such offshoring relationship between a German SME (Small and Medium Enterprise) and their Chinese subsidiary, the trials and tribulations of the collaboration between them, and the implications of this for our understanding of how articulation work might be best supported in the context of global production. We also look at how a separate entity, which we term an ‚articulation hub‘, was established to support articulation between the sites. While a number of studies have looked at articulation work in Global Software Development (GSD), there are very few ethnographic studies of offshored manufacturing, despite the unique challenges it presents. We find here that issues arise not only because of differences in technology environments, infrastructures, and cultural expectations, but also because of differing development strategies and business philosophies. The core problem confronting articulation work in offshored production is the difficulty of arriving at a mutually-grounded intersubjectivity, where shared assumptions about working practices and their relative importance and value can be trusted to apply, leading to what we term ‚intersubjectivity disjunctures‘. These disjunctures have a number of important implications for accomplishing articulation work. This paper offers a number of contributions to CSCW. First, it adds to a very thin corpus of CSCW-relevant ethnographic studies of global manufacturing. Second, it finds that articulation work in offshored production is less closely-coupled than it is in other distributed settings, making conventionally promoted solutions, such as knowledge sharing and relationship building, less relevant. Third, it reveals how differences in moral reasoning can result in different sites assigning very different priorities to articulation work. Finally, while articulation work is typically seen to be invisible work in CSCW, we argue that, in this context, there are a number of ways in which using a separate hub to actively render articulation work visible may be the best solution.

IN Proceedings of the ACM on Human-Computer Interaction, Vol. 7, Pages: 70:1–70:29 doi:10.1145/3579503
[BibTeX] [Abstract] [Download PDF]This study explores the global phenomenon of migration at the local, neighborhood level of a mid-sized city in Germany. Focusing on a long-term interactive storytelling-initiative, it studies the emergence of Arrival Literacy as a bi-directional skill-set. It describes the development of individual, local responses to global migration consequences, among both newcomers who migrated, as well as long-term citizens who never moved. The analytic lens of Arrival Literacy brings forward the complexity and difficulties of the arrival process, where the individual is navigating the consequences of political decisions that were made at a broader level. Digital storytelling as an element is a method to 1) creatively develop a skill of expression for one’s own positionality, and 2) to connect with the positionalities of others, thus supporting the process of dealing with arrival at the local community level and beyond.

[BibTeX] [Abstract] [Download PDF]Technological development continues to advance, with consequences for the use of robots in health care. For this reason, this workshop contribution aims at consideration of how socially assistive robots can be integrated into care and what tasks they can take on. This also touches on the degree of autonomy of these robots and the balance of decision support and decision making in different situations. We want to show that decision making by robots is mediated by the balance between autonomy and safety. Our results are based on Design Fiction and Zine-Making workshops we conducted with scientific experts. Ultimately, we show that robots‘ actions take place in social groups. A robot does not typically decide alone, but its decision-making is embedded in group processes. The concept of heteromation, which describes the interconnection of human and machine actions, offers fruitful possibilities for exploring how robots can be integrated into caring relationships.

(2023)From surplus and scarcity towards abundance: Understanding the use of ICT in food resource sharing practices: “Give a man a fish, and you feed him for a day; teach a man to fish, and you feed him for a lifetime.” – Lao Tsu
IN ACM Transactions on Computer-Human Interaction doi:10.1145/3589957
[BibTeX] [Abstract] [Download PDF]Food practices have become an important context for questions around sustainability. Within HCI, Sustainable HCI and Human-Food-Interaction have developed as a response. We argue, nevertheless, that food practices as a social activity remain relatively under-examined and further that sustainable food practices hinge on communal activity. We present the results of action-oriented research with a grassroots movement committed to sustainable food practices at a local, communal level, thereby demonstrating the role of ICT in making food resource sharing a viable practice. We suggest that the current focus on food sharing might usefully be supplemented by attention to food resource sharing, an approach that aligns with a paradigm shift from surplus to abundance. We argue for design that aims to encourage food resource sharing at a local level but that also has wider ramifications. These ‘glocal’ endeavors recognize the complexity of prosumption practices and foster aspirations for ‘deep change’ in food systems.

[BibTeX] [Abstract] [Download PDF]Much is known about social engineering strategies (SE) during the attack phase, but little is known about the post-attack period. To address this gap, we conducted 17 narrative interviews with victims of cyber fraud. We found that while it was seen to be important for victims to act immediately and to take countermeasures against attack, they often did not do so. In this paper, we describe this „delay“ in victims‘ responses as entailing a period of doubt and trust in good faith. The delay in victim response is a direct consequence of various SE techniques, such as exploiting prosocial behavior with subsequent negative effects on emotional state and interpersonal relationships. Our findings contribute to shaping digital resistance by helping people identify and overcome delay techniques to combat their inaction and paralysis.

IN Proceedings of the ACM on Human-Computer Interaction, Vol. 7, Pages: 26:1–26:26 doi:10.1145/3579459
[BibTeX] [Abstract] [Download PDF]There has been a growing interest in taste research in the HCI and CSCW communities. However, the focus is more on stimulating the senses, while the socio-cultural aspects have received less attention. However, individual taste perception is mediated through social interaction and collective negotiation and is not only dependent on physical stimulation. Therefore, we study the digital mediation of taste by drawing on ethnographic research of four online wine tastings and one self-organized event. Hence, we investigated the materials, associated meanings, competences, procedures, and engagements that shaped the performative character of tasting practices. We illustrate how the tastings are built around the taste-making process and how online contexts differ in providing a more diverse and distributed environment. We then explore the implications of our findings for the further mediation of taste as a social and democratized phenomenon through online interaction.

IN i-com doi:10.1515/icom-2022-0045
[BibTeX] [Abstract] [Download PDF]3D printers are no longer found only in industry, universities or makerspaces but now are increasingly used in domestic settings. Personal fabrication will increase in the coming years, and 3D printing will play an important role in this process. Due to technology and price development, 3D printers are becoming established among casual users at home. However, there are still many hurdles in the use of 3D printers that interfere with their appropriation in everyday life. In this paper, we investigate how chatbots can overcome these hurdles and support onboarding to 3D printing. Furthermore, we explore how chatbots can be used as a human–machine interface and facilitate interaction with 3D printers for both novice and expert users. In a research-through-design approach, we have created a fully functional chatbot that introduces users to 3D printing and helps them perform typical tasks when operating 3D printers.

Hille, N., Bürvenich, B., Carros, F., Manavi, M., Wieching, R., Matsumoto, Y. & Wulf, V. (2023)The Effects of Android Robots Displaying Emotion on Humans: Interactions between Older Adults and Android Robots
, Publisher: arXiv doi:10.48550/arXiv.2303.13624
[BibTeX] [Abstract] [Download PDF]Often robots are seen as a means to an end to fulfill a logical objective task. Android robots, on the other hand, provide new possibilities to fulfill emotional tasks and could therefore be integrated into assistive scenarios. We explored this possibility by letting older adults and stakeholders have a conversation with an android robot capable of expressing emotion through facial expressions. The study was carried out with a wizard-of-oz approach and data collected with a mixed methods approach. We found that the participants were encouraged to speak more with the robot due to its smile. Simultaneously, many ethical questions were raised about transparency and manipulation. Our research can give valuable insight into the reaction of older adults to android robots that show emotions.

Pinto, L. S. (2023)LUNA: HCI for Supporting Abused Women in Mexico
, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]Cases of domestic violence around the globe can no longer endure at this day and age. The World Health Organization estimates one out of three women in the globe being subjected to either physical and/or sexual intimate partner violence or non-partner sexual violence in their lifetime [51]. In most Latinamerican countries, the numbers are worse. In Mexico, 43.9\% of women aged 15 years and older (19.1 million) reported being victims of intimate partner abuse over the last decades [20]. HCI seeks to tackle this problem and does so successfully in some regions of the world. For LATAM, this technological battle is full of opportunities. Women in Mexico City that suffer domestic violence seek help at LUNA, government centres dedicated to offer free services such as psychological advice, legal assistance and refuge to all women. However, as an NPO, LUNA is understaffed, underequipped and underbudgeted, making it challenging for employees, managers and directors to perform effectively. In this paper, I present a dashboard designed with a participatory approach (by including users along the whole design process) that has proven to enhance employee’s quality of service by improving the usability of their registration system. Moreover, this dashboard offers a friendlier visualisation of the victims’ data for an improved follow-up service and allows a more efficient interdisciplinary collaboration. This tool equips the LUNA director with the means to analyse their data properly as to identify patterns that will lead to better strategies and executive decisions, as well as to demand the proper budget and assistance they require. The dashboard features serve as the evidence required for policy creation in Mexico, allowing the opportunity for social change on scale. By referencing studies on Data & Bureaucracy and Gender Violence, this paper aims to add to the discussion in LATAM to tackle domestic violence through HCI.

[BibTeX] [Abstract] [Download PDF]Over the last three years, COVID-19, with its lockdowns, social restrictions, and work from home structures, had a significant influence on our daily lives. The resulting changes in technology practices are likely to be explored in the years ahead. We will contribute to this exploration by looking specifically at the impact of COVID-19 on everyday food practices and the role of involved technology. To explore food practices and technology use, we conducted a qualitative interview study with 16 interviewees and delved into the underlying influencing factors behind them. Thereby we can better understand potential behavioral changes and technology usage by people to design not only for future pandemics and exceptional situations but to also for non-pandemic times.

Clausen, L. C. (2023)How to design a motivating e-learning concept for students for a social (informal) exchange of information in the digital age?
Thesis, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]In recent decades e-learning is becoming increasingly important in higher education due to the rapid development of digitalisation. E-learning not only offers opportunities to reinvent and support learning but could also provide an answer to how to cope with the rapidly changing information in 21st century society. However, the focus of higher education was on face-to-face courses until March 2020, when the COVID-19 pandemic required a rapid shift to e-learning. E-learning enabled students around the world to continue their studies, but also brought many new challenges for them. While formal study communication with lectures could be converted to an e-learning format, informal communication among students, which is also an essential part of the study and learning experience, suffered. This lack of communication was accompanied by a decline in student motivation and well-being. This master’s thesis investigates these e-learning problems, analyses modern e-learning approaches and technologies, and creates a concept that supports the mostly informal information exchange between students. The concept is based on the pedagogical ideas of Constructivism, Connectivism, and Adult Learning Theory. This leads to the choice of using the collective learning approaches Community of Practice, Artistic Pedagogical Technologies, Microlearning and Microtraining combined and to integrate them in the open-source platform Humhub. The concept and platform are evaluated in a small qualitative study. The results provide a starting point to create a better e-learning experience for students – not only during the COVID-19 pandemic, but also in the future as the digitalisation of higher education will continue to grow.

Ajiboye, C. D. (2023)Designing Benchmark Application for Stress Elicitation
, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]The design and development of digital tools to fast-track and automate research processes has been a topical issue in the world of research over the years. Stakeholders and research experts have been working assiduously to come up with superior ideas that will give rise to the development of cutting-edge technological tools for research and experimental purposes. In this study, the focus is on how a digital tool that will serve as a benchmark App for inducing/elicit stress can be design with the use of User centered design principles. To actualize this, a literature review was first conducted to understand the social practice and also identify some underlying issues that might exist. Thereafter, the design case study framework consisting of three phases (pre study, design and appropriation) was implemented all through the design process. The insights gathered during the qualitative interview phase and the user needs and pain points discovered during the user workshop phases were all implemented in the High fidelity prototypes that were generated for the final App design. The designed interfaces were then tested and evaluated by users using the thinking aloud method so as to discover usability issues that needed to be fixed for the improvement of the overall user experience of the product. In line with the results obtained during the evaluation, recommendations were given on how this work can be further developed to have a fully functional application that is appropriated and tailored to meet the specific needs of the users.

Rüller, S., Aal, K., Tolmie, P., Randall, D., Rohde, M. & Wulf, V. (2023)Rurality and Tourism in Transition: How Digitalization Transforms the Character and Landscape of the Tourist Economy in Rural Morocco
[BibTeX] [Abstract] [Download PDF]
The character of rural Morocco is changing due to increasing tourism and social media usage. This paper outlines the different consequences of ICT usage among people working in the tourism sector as part of the transitional economy in a remote area. In this region, tourism has grown into one major income sources for a few valley inhabitants – mostly men with a school education, digital and language skills, and who are financially stable. As this transitional economy evolves alongside digitalization and ICT usage and therefore a change of the region’s rural character, it leads to challenges and concerns for the local population. This ethnographic study analyzes the interdependence of increasing tourism through digitalization and the notion of rurality as a resource from a sociotechnical perspective.

Hieber, L. (2022)Accessible Museums through 3D Printing
, Siegen
[BibTeX] [Abstract] [Download PDF]Accessibility is an important topic for museums to enable people with (visual) impairments experience art and culture. Although there are several regulations by the European Union (EU) and the German Federal Republic for more accessibility, also in the cultural area, visually impaired people still face a lot of barriers. Nevertheless, there are various concepts to overcome these shortcomings such as audio descriptive guides or descriptions in braille. One of several methods of inclusion are 3D printed exhibits, offered as touch objects. This idea is also pursued by a museum near Siegen – the Ginsburg. Using the Ginsburg as an example this thesis aims to describe the role and potential of 3D printing in replicating historical artefacts. Following a holistic approach, the possibilities for additional enhancement of these 3D prints to promote accessibility to the visually impaired are explored. For this purpose, a design case study was conducted. This started with a literature review on visual impairment and current developments in museums as well as in 3D printing. Then, an empirical pre-study was performed. To understand current practices as well as underlying issues, 11 semi-structured interviews were carried out with blind people. Based on this, interactive Prototypes were developed using different 3D printing techniques in combination with various output modalities for audio comments. One version works with QR codes, the other version with conductive filament. Finally, the prototypes were evaluated with blind and sighted participants. The pre-study and the evaluation clearly show that there is a need for interactive exhibits such as those developed here. To provide significant added value for visually impaired museum visitors, they must not be limited to touch objects alone, but need to be enriched with additional information. Since not all blind people – especially late-blind people – can read textual information in braille, audio commentaries are an indispensable aid. Of the two versions developed, V2 is more promising. However, since V2 still exhibits considerable flaws, a further iteration of the prototype is strongly recommended before it is integrated as a permanent part of the exhibit at the Ginsburg. Independently of the Ginsburg, such interactive touch objects offer great potential for more accessible museums in general and could add value not only for the visually impaired, but for all museum visitors.

IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09458-z
[BibTeX] [Abstract] [Download PDF]Artificial intelligence and the underlying machine learning (ML) methods are increasingly finding their way into our working world. One of these areas is sales planning, where machine learning is used to leverage a variety of different input parameters such as prices, promotions, or the weather, to forecast sales, and therefore directly affects the production of products and goods. To satisfy the goal of environmental sustainability as well as address short shelf life, the food industry represents an interesting application field for the use of ML for optimizing sales planning. Within this paper, we will examine the design, and especially the application, of ML methods in the food industry and show the current challenges that exist in the use of such concepts and technologies from the end-user’s point of view. Our study of a smaller bakery company shows that there are enormous challenges in setting up the appropriate infrastructure and processes for the implementation of ML, that the output quality of ML processes does not always match the perceived result quality, and that trust in the functioning of the algorithms is the most important criterion for using ML processes in practice.

Predicting PTC preferences in a smart home can be a prerequisite to adjusting the indoor temperature for providing a comfortable environment. In this research, we focus on identifying relevant features for predicting PTC preferences. We propose a machine learning-based predictive framework by employing supervised feature selection techniques. We apply two feature selection techniques to select the optimal sets of features to improve the thermal preference prediction performance. The experimental results on a public PTC dataset demonstrated the efficiency of the feature selection techniques that we have applied. In turn, our PTC prediction framework with feature selection techniques achieved state-of-the-art performance in terms of accuracy, Cohen’s kappa, and area under the curve (AUC), outperforming conventional methods.

[BibTeX] [Abstract] [Download PDF]Despite various attempts to prevent food waste and motivate conscious food handling, household members find it difficult to correctly assess the edibility of food. With the rise of ambient voice assistants, we did a design case study to support households’ in situ decision-making process in collaboration with our voice agent prototype, Fischer Fritz. Therefore, we conducted 15 contextual inquiries to understand food practices at home. Furthermore, we interviewed six fish experts to inform the design of our voice agent on how to guide consumers and teach food literacy. Finally, we created a prototype and discussed with 15 consumers its impact and capability to convey embodied knowledge to the human that is engaged as sensor. Our design research goes beyond current Human-Food Interaction automation approaches by emphasizing the human-food relationship in technology design and demonstrating future complementary human-agent collaboration with the aim to increase humans’ competence to sense, think, and act.

Hoffmann, S., Pinatti de Carvalho, A. F., Schweitzer, M., Abele, N. D. & Wulf, V. (2022)Producing and Consuming Instructional Material in Manufacturing Contexts: Evaluation of an AR-based Cyber-Physical Production System for Supporting Knowledge and Expertise Sharing
IN Proceedings of the ACM on Human-Computer Interaction, Vol. 6, Pages: 366:1–366:36 doi:10.1145/3555091
[BibTeX] [Abstract] [Download PDF]Fast-paced knowledge and expertise sharing (KES) is a typical demand in contemporary workplaces due to dynamic markets and ever-changing work practices. Past and current computer supported cooperative work (CSCW) research has long been investigating how computer technologies can support people with KES. Recent claims have asserted that augmented reality- (AR-)based cyber-physical production systems (CPPS) are poised to bring significant changes in the ways that KES unfolds in manufacturing contexts. This paper scrutinises such claims by implementing a short-term evaluation of an AR-based CPPS and assessing how it can potentially support (1) the generation of AR content by experienced production workers and (2) the visualisation and processing of such content by novice workers. We, therefore, contribute a user study to the CSCW community that sheds light on the use of a particular type of AR-based CPPS for KES in industrial contexts.?

Grinko, M., Qalandar, S., Randall, D. & Wulf, V. (2022)Nationalizing the Internet to Break a Protest Movement: Internet Shutdown and Counter-Appropriation in Iran of Late 2019
IN Proceedings of the ACM on Human-Computer Interaction, Vol. 6, Pages: 314:1–314:21 doi:10.1145/3555205
[BibTeX] [Abstract] [Download PDF]To deal with a spontaneous civil uprising following a substantial rise in gas prices, the Iranian security apparatus imposed in late 2019 techno-political measures and blocked access to international websites and services. To analyze these measures, we conducted 19 interviews with Iranians living inside and outside the country. We argue that the concept of the shutdown, as portrayed in Western media, is not perfectly suitable to describe the infrastructural restrictions and propose the concept of an internet nationalization. This paper offers an in-depth analysis of what the nationalization meant and how it affected the lives of Iranians participating or not participating in the protests. We also report on a variety of creative measures, both technical and non-technical, Iranians took to counter-appropriate the government-imposed shutdown of international connectivity. Based on these data, we elaborate on the concept of counter-appropriation.

doi:10.1145/3555180
[BibTeX] [Abstract]In this paper, we introduce an innovative design concept for the curation of data, which we call ‚Data Story‘. We view this as an additional resource for data curation, aimed specifically at supporting the sharing of qualitative and ethnographic data. The Data Story concept is motivated by three elements: 1. the increased attention of funding agencies and academic institutions on Research Data Management and Open Science; 2. our own work with colleagues applying ethnographic research methods; and 3. existing literature that has identified specific challenges in this context. Ongoing issues entailed in dealing with certain contextual factors that are inherent to qualitative research reveal the extent to which we still lack technical design solutions that can support meaningful curation and sharing. Data Story provides a singular way of addressing these issues by integrating traditional data curation approaches, where research data are treated as ‚objects‘ to be curated and preserved according to specific standards, with a more contextual, culturally-nuanced and collaborative organizing layer that can be thought of as a „Story“. The concept draws on existing literature on data curation, digital storytelling and Critical Data Studies (CDS). As a possible design solution for Research Data Management and data curation, Data Story offers: 1) a collaborative workflow for data curation; 2) a story-like format that can serve as an organizing principle; 3) a means of enhancing and naturalizing curation practices through storytelling. Data Story is currently being developed for deployment and evaluation.

Shajalal, M., Boden, A. & Stevens, G. (2022)Explainable product backorder prediction exploiting CNN: Introducing explainable models in businesses
IN Electronic Markets doi:10.1007/s12525-022-00599-z
[BibTeX] [Abstract] [Download PDF]Due to expected positive impacts on business, the application of artificial intelligence has been widely increased. The decision-making procedures of those models are often complex and not easily understandable to the company’s stakeholders, i.e. the people having to follow up on recommendations or try to understand automated decisions of a system. This opaqueness and black-box nature might hinder adoption, as users struggle to make sense and trust the predictions of AI models. Recent research on eXplainable Artificial Intelligence (XAI) focused mainly on explaining the models to AI experts with the purpose of debugging and improving the performance of the models. In this article, we explore how such systems could be made explainable to the stakeholders. For doing so, we propose a new convolutional neural network (CNN)-based explainable predictive model for product backorder prediction in inventory management. Backorders are orders that customers place for products that are currently not in stock. The company now takes the risk to produce or acquire the backordered products while in the meantime, customers can cancel their orders if that takes too long, leaving the company with unsold items in their inventory. Hence, for their strategic inventory management, companies need to make decisions based on assumptions. Our argument is that these tasks can be improved by offering explanations for AI recommendations. Hence, our research investigates how such explanations could be provided, employing Shapley additive explanations to explain the overall models’ priority in decision-making. Besides that, we introduce locally interpretable surrogate models that can explain any individual prediction of a model. The experimental results demonstrate effectiveness in predicting backorders in terms of standard evaluation metrics and outperform known related works with AUC 0.9489. Our approach demonstrates how current limitations of predictive technologies can be addressed in the business domain.

IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09444-5
[BibTeX] [Abstract] [Download PDF]The coordination of maintenance work in manufacturing poses a crucial productivity factor in small and medium-sized companies (SMEs) but often seems to be rather neglected in practice as well as in much of the literature on maintenance. We shed light upon maintenance coordination work by presenting a design case study conducted in an SME over approximately two years. We took a participatory design-oriented approach, involving all roles on the shopfloor affected by maintenance work. In three major iterations during the pre-study, a release-ready prototype was developed and implemented by the users over the course of one year. The evaluation of the tool showed how a new and mostly unintended practice of information flow, error reporting, and prioritization emerged such that, for instance, foremen becoming a central node of communication, formal prioritization shifting away from higher management, and actual prioritization being done by maintainers. This paper contributes to the body of CSCW work on maintenance practice in SMEs by presenting detailed empirical findings on the coordination work of maintainers, as well as the evaluation of socio-technical interventions into maintenance practices.

[BibTeX] [Abstract] [Download PDF]For most people, using their body to authenticate their identity is an integral part of daily life. From our fingerprints to our facial features, our physical characteristics store the information that identifies us as „us.“ This biometric information is becoming increasingly vital to the way we access and use technology. As more and more platform operators struggle with traffic from malicious bots on their servers, the burden of proof is on users, only this time they have to prove their very humanity and there is no court or jury to judge, but an invisible algorithmic system. In this paper, we critique the invisibilization of artificial intelligence policing. We argue that this practice obfuscates the underlying process of biometric verification. As a result, the new „invisible“ tests leave no room for the user to question whether the process of questioning is even fair or ethical. We challenge this thesis by offering a juxtaposition with the science fiction imagining of the Turing test in Blade Runner to reevaluate the ethical grounds for reverse Turing tests, and we urge the research community to pursue alternative routes of bot identification that are more transparent and responsive.

Smart City research and practice has put emphasis on the importance of citizen-centric processes, collaborating with citizens and other stakeholders, as well as public values in Smart City projects. Nevertheless, cities and governmental organizations continue to adopt technology-push approaches, marginalized citizens such as refugees are often excluded in (urban) digitalization and decision-making processes. Despite their different and valuable perspectives, collaborating with marginalized citizens is not common practice, as it often requires a different approach than traditional citizen participation techniques. During this workshop, we will discuss with Smart City practitioners and refugees how we could broaden participation to include citizens who are still excluded, using a visual card-based game to discuss topics in the Smart City context that are relevant to participants. The expected outcomes of this workshop are an understanding of opportunities for involving marginalized citizens (in this workshop: refugees) in Smart City projects, different perspectives of stakeholders involved, and the setting up of a learning and caring community in which different stakeholders can share their insights and practices.

The expected outcomes of this workshop are an understanding of opportunities for involving marginalized citizens (in this workshop: refugees) in Smart City projects, different perspectives of stakeholders involved, and the setting up of a learning and caring community in which different stakeholders can share their insights and practices.}, urldate = {2022-10-04}, booktitle = {Adjunct {Proceedings} of the 2022 {Nordic} {Human}-{Computer} {Interaction} {Conference}}, publisher = {Association for Computing Machinery}, author = {Scheepmaker, Laura and Aal, Tanja and Kender, Kay and Vallis, Stacy and Aal, Konstantin and Smith, Nancy and Melenhorst, Mark and Van Twist, Anouk and Veenstra, Mettina and Schuler, Douglas and Müller, Claudia and Wulf, Volker and Weibert, Anne and Weibert, Anne and Weibert, Anne and Weibert, Anne}, month = oct, year = {2022}, keywords = {HCI, Participatory design, refugees, Smart Cities, marginalized people}, pages = {1--5}, } -

[BibTeX] [Abstract] [Download PDF]The rapid development of digital technologies and their increasing application in many areas of everyday life challenge all citizens to continuously learn digital skills. This also applies to older adults, among whom digital literacy is on average less well-developed than among younger adults. This article investigates why retired older adults participate in opportunities to learn digital skills. Multiple case design with both qualitative and quantitative methods was used to include the views of older adults from Austria, Finland, and Germany. The results of this interdisciplinary study indicated individual, social and technical reasons for their participation in digital skills training. Practical implications and recommendations for future studies are suggested.

von Grafenstein, M., Jakobi, T. & Stevens, G. (2022)Effective data protection by design through interdisciplinary research methods: The example of effective purpose specification by applying user-Centred UX-design methods
IN Computer Law & Security Review, Vol. 46, Pages: 105722 doi:10.1016/j.clsr.2022.105722
[BibTeX] [Abstract] [Download PDF]While the recent discussion on Art. 25 GDPR often considers the approach of data protection by design as an innovative idea, the notion of making data protection law more effective through requiring the data controller to implement the legal norms into the processing design is almost as old as the data protection debate. However, there is another, more recent shift in establishing the data protection by design approach through law, which is not yet understood to its fullest extent in the debate. Art. 25 GDPR requires the controller to not only implement the legal norms into the processing design but to do so in an effective manner. By explicitly declaring the effectiveness of the protection measures to be the legally required result, the legislator inevitably raises the question of which methods can be used to test and assure such efficacy. In our opinion, extending the legal compatibility assessment to the real effects of the required measures opens this approach to interdisciplinary methodologies. In this paper, we first summarise the current state of research on the methodology established in Art. 25 sect. 1 GDPR, and pinpoint some of the challenges of incorporating interdisciplinary research methodologies. On this premise, we present an empirical research methodology and first findings which offer one approach to answering the question on how to specify processing purposes effectively. Lastly, we discuss the implications of these findings for the legal interpretation of Art. 25 GDPR and related provisions, especially with respect to a more effective implementation of transparency and consent, and provide an outlook on possible next research steps.

Naveed, S., Stevens, G. & Kern, D. (2022)Explainable Robo-Advisors: Empirical Investigations to Specify and Evaluate a User-Centric Taxonomy of Explanations in the Financial Domain
Proceedings of the 9th Joint Workshop on Interfaces and Human Decision Making for Recommender Systems co-located with 16th ACM Conference on Recommender Systems (RecSys 2022). Seattle, USA, Pages: 85–103
[BibTeX] [Abstract] [Download PDF]Even though Recommender Systems (RS) have been widely applied in various financial domains such as Robo-advisors (RA), these systems still operate as a black box with no or limited explanations. Even in cases, where explanations are provided, such systems are mostly designed from the developers’ perspective where the user needs and perspective of explanations are not taken into account. In this work, we aim to address the challenges of designing eXplainable Robo-Advisors (XRA) – by adopting a user-centric methodology. For this purpose, we applied a mixed-method approach, in whichwe conducted three qualitative focus group discussions (FGD) and supplemented the results with a quantitative survey insight. More specifically, we made two major contributions: 1) We extended the existing explanation categories to contextualize it for the financial domain – by identifying the user’s specific needs for explainability in the context of the financial domain, 2) We quantified the user preferences of specific explanations with regard to the financial domain and explainable RA – by evaluating the user’s personal relevance (PRE) and perceived quality (PQE) of explanations.

In this study, we analyse the effects of the new version of the zoomorphic robot AIBO on people with disabilities living in residential care homes. We observed the interaction for four weeks, giving the care workers and residents complete control of the robot. We specifically looked at factors like well-being and interaction strategies. Our findings show mixed results. Whereas AIBO seems to have positive effects on some residents, e.g. reducing loneliness and enhancing personal well-being, others relate less positively to its limited functions and language restrictions. This study indicates that AIBO has the potential to be used meaningfully in real-world care contexts in Germany but needs improvement to have a fully positive impact.

Ahmadi, M., Taugerbeck, S., Meurer, J., Randall, D. & Wulf, V. (2022)Addressing Values in Co-Design Projects: Lessons Learned From Two Case Studies in Sensitive Contexts
IN Interacting with Computers doi:10.1093/iwc/iwac024
[BibTeX] [Abstract] [Download PDF]Human–computer interaction (HCI) scholars and others have advocated treating design as inevitably implicating political and ethical sensitivities. A subset of those considerations has been the attempt to deal with the often conflicting interests of stakeholders through ‘value sensitivity’. Drawing on value-sensitive design (VSD) as an inspiration, we emphasize the necessary way in which the evolving contextuality of the values in question shaped our research collaborations. This paper presents a retrospective analysis of two case studies from long-term user-centered design projects in fields with explicit ambitions for value-driven HCI research and concerned with emancipation and empowerment. The first, a 3-year project, entailed an explicit commitment to feminist policy initiatives with female participants that aimed at fostering values of gender equality. The second, a 4-year project, dealt with HCI research with and for older adults, where a multimodal mobility platform for ridesharing and public transportation was developed. We show how we translated general commitment into pragmatic, co-design research goals and infrastructures. The long-term ambition of our endeavors and integration of a broad stakeholder base were vital to support this. We additionally provide insights into how our approach offered safe spaces for trustful collaboration and flexibility when adapting methods to specific contexts.

IN Mensch und Computer 2022 – Tagungsband doi:10.1145/3543758.3543781
[BibTeX] [Abstract] [Download PDF]Taste is a complex phenomenon that depends on the individual experience and is a matter of collective negotiation and mediation. On the contrary, it is uncommon to include taste and its many facets in everyday design, particularly online shopping for fresh food products. To realize this unused potential, we conducted two Co-Design workshops. Based on the participants’ results in the workshops, we prototyped and evaluated a click-dummy smartphone app to explore consumers’ needs for digital taste depiction. We found that emphasizing the natural qualities of food products, external reviews, and personalizing features lead to a reflection on the individual taste experience. The self-reflection through our design enables consumers to develop their taste competencies and thus strengthen their autonomy in decision-making. Ultimately, exploring taste as a social experience adds to a broader understanding of taste beyond a sensory phenomenon.

After reviewing current approaches and design guidelines, we designed and implemented FADER, a web-based tool for creating AR-based food avatars. Our evaluation shows that playful design fosters immersion, and that abstract placeholders and highly simplified controls empower non-developers to create AR content.

Carros, F., Störzinger, T., Wierling, A., Preussner, A. & Tolmie, P. (2022)Ethical, Legal & Participatory Concerns in the Development of Human-Robot Interaction: Lessons from Eight Research Projects with Social Robots in Real-World Scenarios
IN i-com, Vol. 21, Pages: 299–309 doi:10.1515/icom-2022-0025
[BibTeX] [Abstract] [Download PDF]Research on Human-Robot Interaction is increasing as system become widely available and reached a level that enables smooth interactions. Yet, many research projects act in a silo mentality, in regard of participatory, ethical, or legal matters of social robotics. Knowledge about specific challenges is not universal and has often to be transferred from non-robotic contexts. We present findings in the three dimensions: participatory design, ethics for social robots and legal aspects. We accompanied eight research projects on social robots in real-world scenarios for three years. During that time, we spoke, observed, and helped (where possible) the research projects. This gave us specific insights into their work. Our findings work in three dimensions. In participatory design we observed that the trust relationship to users is essential to gain truthful insights and that a mixed method approach is promising. Regarding ethical aspects, we could see that ethical matters should be answered early on.

Yet, many research projects act in a silo mentality, in regard of participatory, ethical, or legal matters of social robotics. Knowledge about specific challenges is not universal and has often to be transferred from non-robotic contexts. We present findings in the three dimensions: participatory design, ethics for social robots and legal aspects. We accompanied eight research projects on social robots in real-world scenarios for three years. During that time, we spoke, observed, and helped (where possible) the research projects. This gave us specific insights into their work. Our findings work in three dimensions. In participatory design we observed that the trust relationship to users is essential to gain truthful insights and that a mixed method approach is promising. Regarding ethical aspects, we could see that ethical matters should be answered early on. And in the legal dimensions we noticed that the GDPR regulations are a challenge that often requires the help of experts.

Omar, R. (2022)The Role of Technology in Knowledge Management in SME’s
Bachelor {Thesis}, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]The research objective of this thesis is to : 1) Understanding the phenomena of knowledge sharing in organizations. 2) And to understand the role of information technologies for sharing knowledge in companies? The research design for this work is based on the design science research methodology introduced by Vaishnavi and Kuechler (2008). Awareness of the problem was done by by doing ethnography in a software company. Data was collected using ethnomethodology through shadowing and doing semistructured interviews with the 8 employees from the consulting, sales, and Support and quality departments. Data was analyzed by thematic analysis after recording the interviews and taking the observations notes, they were transcribed, including the breaks, reactions, and emotions. The analysis led to the suggestion and definition of different facets and caveats of the knowledge sharing phenomenon which resulted in the prototyping of an interactive solution for knowledge sharing based on the Game theory that aims to improve the way knowledge is shared within the company, intending to reduce the wasted time and costs for an organization and enhancing the motivation of new employees during training.

(2022)Analyse eines Kennzahlensystems zur Identifizierung von Optimierungspotentialen in der Produktion
Bachelorthesis, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]Unternehmen stehen durch die Globalisierung und demographischen Wandel unterschiedlichen Herausforderungen gegenüber. Zum einen gibt es einen stark steigenden Fachkräftemangel, zum anderen steigen die Anforderungen der Kunden an individuelle Produkte. Damit Unternehmen trotz Personalengpässen und individuellen Kundenanforderungen effizient produzieren können, müssen Arbeitspraktiken und Prozesse ständig optimiert werden. Zur Identifizierung von Optimierungspotentialen eignet sich ein fertigungswirtschaftliches Kennzahlensystem. Diese Bachelorarbeit beschäftigt sich mit der Analyse eines Kennzahlensystems zur Identifizierung von Optimierungspotentialen in der Produktion. Das Ziel ist die Steigerung der Effizienz der Produktion durch Reduzierung der Durchlaufzeiten eines Fabrikats. Im ersten Schritt wurden Kennzahlen für Abteilungsleiter der Produktion eines mittelständischen Unternehmens visualisiert. Diese Reports wurden in einer Ishikawa-Analyse untersucht, um Einflussgrößen auf die durchschnittliche Durchlaufzeit eines Containers zu ermitteln. Dazu wurde ermittelt, welche Schlussfolgerungen die Führungskräfte aus den Kennzahlen ziehen. Daraus ging unter anderem hervor, dass die Fertigungs- und Personalplanung bei einem Unternehmen mit unterschiedlichen Produktvarianten und verschiedenen Gewerken einen großen Einfluss auf die Effizienz der Fertigung hat. Daher beschäftigt sich der zweite Teil mit der Fragestellung: Inwiefern können Kennzahlen zur präziseren und effizienteren Fertigungs- und Personalplanung genutzt werden? Dazu wurde in einer Evaluation ermittelt, bei welchen Tätigkeiten die Mitarbeiter durch die Kennzahlenapps unterstützt wurden. Kennzahlen ermöglichen es, den aktuellen Zustand einer Fertigung zu messen. Die Ergebnisse der Evaluation zeigen, dass diese Informationen als objektive Informationsgrundlage genutzt werden können, um eine zeitliche Aufwandsabschätzung der Fertigungsaufträge vorzunehmen oder Personalengpässe zu prognostizieren. Eine geeignete Visualisierung der Kennzahlen unterstützt zusätzlich eine schnelle Entscheidungsfindung und transparente Präsentation von Handlungsempfehlungen. Unterscheiden sich die Bearbeitungszeiten der Produktvarianten einer Fertigungslinie, kann der Prozessfluss gestört werden. Bei solchen Problemen können Kennzahlen genutzt werden, um eine optimale Bearbeitungsreihenfolge der Aufträge zu definieren und Optimierungspotentiale zur Neugestaltung der Fertigungslinie aufzudecken, damit Mitarbeiterkapazitäten optimal genutzt werden können.

IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09442-7
[BibTeX] [Abstract] [Download PDF]Within CSCW and HCI, an increasing body of literature has been demonstrating the essential relevance of infrastructures and infrastructuring to the work of people engaging in technologically mediated nomadicity. Tech Nomads – or T-Nomads, as they are sometimes called – not only rely on technological, human, and environmental infrastructural components – such as Wi-Fi, technical support, space, and basic resources such as light and power outlets – but they also have to engage in infrastructuring to mobilise their workplaces and effectively accomplish work in and across different locations. In this article, we bring an infrastructuring perspective to understanding nomadic practices concerning the organisation of complex collaborative events. We introduce findings from a long-term investigation focusing on how infrastructures are re-instantiated with the help of digital technologies, according to emerging demands from T-Nomads. Our findings demonstrate the need for a ‘non-essentialist’ approach to nomadicity, one which recognises the character of nomadic work and its varied aspects in different contexts. We extend the infrastructuring literature by demonstrating how infrastructuring work is done in a complex collaborative initiative, as the organisation of the annual European Social Forum.

[BibTeX] [Abstract] [Download PDF]Technology use is a socially embedded process, especially when it comes to older adults and care. However, the restrictions associated with the COVID-19 pandemic have limited social contact to protect vulnerable groups in care homes, and even if technology use has increased in other areas, there is little known about the potential uptake of communication technology and changes in social interaction in the care context during a lasting crisis. This paper explores changes in communication technology use triggered by the pandemic at two care homes, using a qualitative diary study, online interviews and observations, and in-situ interviews within the care home with residents and workers. Our findings point to increasing use of tablets and video conference software triggered by COVID-related experiences, with implications for living and working in care homes. We also characterise the isolation experience of the residents, the workers’ concerns about the residents and changes in social interaction. We observed new areas of technology usage, associated changing work practices, technical affinity issues and context-specific attitudes towards future technologies. While the pandemic has triggered the use of communication technology in care homes on a small scale, this has also caused increasing workload and in particular articulation work, which requires support structures and the re-definition of work roles.

IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09430-x
[BibTeX] [Abstract] [Download PDF]Since almost the onset of computer-supported cooperative work (CSCW), the community has been concerned with how expertise sharing can be supported in different settings. Here, the complex handling of machines based on experience and knowledge is increasingly becoming a challenge. In our study, we investigated expertise sharing in a medium-sized manufacturing company in an effort to support the fostering of hardware-based expertise sharing by using augmented reality (AR) to ‘retrofit’ machines. We, therefore, conducted a preliminary empirical study to understand how expertise is shared in practice and what current support is available. Based on the findings, we derived design challenges and implications for the design of AR systems in manufacturing settings. The main challenges, we found, had to do with existing socio-technical infrastructure and the contextual nature of expertise. We implemented a HoloLens application called RetrofittAR that supports learning on the production machine during actual use. We evaluated the system during the company’s actual production process. The results show which data types are necessary to support expertise sharing and how our design supports the retrofitting of old machines. We contribute to the current state of research in two ways. First, we present the knowledge-intensive practice of operating older production machines through novel AR interfaces. Second, we outline how retrofitting measures with new visualisation technologies can support knowledge-intensive production processes.

The aim is to increase the acceptance, trust, and transparency of AI models by providing explanations about the models‘ decisions. But most of the prior works on XAI are focused to support AI practitioners and developers in understanding and debugging. In this paper, we propose a user-centered explainable energy demand prediction and forecasting system that aims to provide explanations to end-users in the smart home. In doing so, we present an overview of the explainable system and propose a method combining Deep Learning Important FeaTures (DeepLIFT) and Shapley Additive Explanations (SHAP) to explain the prediction of an LSTM-based energy forecasting model.

[BibTeX] [Abstract] [Download PDF]Aim of this study is to investigate the efects of user experience (UX) on shopping mall customers’ intention to use a social robot. Therefore, we used a Wizard of Oz approach that enabled data collection in situ. Quantitative data was obtained from a questionnaire completed by shopping mall customers who interacted with a social robot. Data was used in a regression analysis, where user experience factors served as predictors for robot use in retail. The regression model explains up to 23.2\% of the variance in customers’ intention to use a social robot. In addition, we collected qualitative data on human-robot-interactions and used the data to complement the interpretation of statistical results. Our fndings suggest that only hedonic qualities signifcantly contribute to the prediction of customers’ intention, that shopping mall customers are reluctant to grant pragmatic qualities to social robots, and that UX evaluation in HRI requires additional predictors.

Böhm, L., Peters, F., Bossauer, P., Lawo, D., Pakusch, C. & Stevens, G. (2022)Designing a Mobility Intelligence System for Decision-making with Shared Mobility Data
, Publisher: IEEE Computer Society, Pages: 53–64 doi:10.1109/ICT4S55073.2022.00017
[BibTeX] [Abstract] [Download PDF]Shared mobility has the potential to become an important driver for sustainable mobility. However, the rapid growth of services in already congested urban areas presents cities with major challenges. It becomes apparent that cities lack tools to manage mobility across all shared mobility services. We propose a mobility intelligence system for cities to leverage the vast amounts of data generated by shared fleets for decision-making. The system is designed to support cities in monitoring, regulating, and optimizing shared mobility. A dashboard provides access to data across all different services. Besides tools for regulating providers, e.g., with no-parking zones, we also provide access to mobility-specific machine learning methods, such as demand prediction. We rely on open source standards for data sharing between cities and providers to facilitate collaboration. The system is designed and implemented as a prototype based on requirements from discussions with cities, public transport agencies, and mobility researchers. As part of the evaluation, eight shared mobility experts tested the system. The results validate the system&\#x2019;s usability for three task scenarios while also revealing potential for future research and development.

The system is designed to support cities in monitoring, regulating, and optimizing shared mobility. A dashboard provides access to data across all different services. Besides tools for regulating providers, e.g., with no-parking zones, we also provide access to mobility-specific machine learning methods, such as demand prediction. We rely on open source standards for data sharing between cities and providers to facilitate collaboration. The system is designed and implemented as a prototype based on requirements from discussions with cities, public transport agencies, and mobility researchers. As part of the evaluation, eight shared mobility experts tested the system. The results validate the system\&\#x2019;s usability for three task scenarios while also revealing potential for future research and development.}, language = {English}, urldate = {2022-08-09}, publisher = {IEEE Computer Society}, author = {Böhm, Lukas and Peters, Felix and Bossauer, Paul and Lawo, Dennis and Pakusch, Christina and Stevens, Gunnar}, month = jun, year = {2022}, pages = {53--64}, } -
Esau, M., Krauß, V., Lawo, D. & Stevens, G. (2022)Losing Its Touch: Understanding User Perception of Multimodal Interaction and Smart Assistance
Designing Interactive Systems Conference. Virtual Event Australia, Publisher: ACM, Pages: 1288–1299 doi:10.1145/3532106.3533455
[BibTeX] [Abstract] [Download PDF]Intelligent Personal Assistants (IPA) are advertised as reliable companions in the everyday life to simplify household tasks. Due to speech-based usability issues, users struggle to deeply engage with current systems. The capabilities of newer generations of standalone devices are even extended by a display, also to address some weaknesses like memorizing auditive information. So far, it is unclear how the potential of a multimodal experience is realized by designers and appropriated by users. Therefore, we observed 20 participants in a controlled setting, planning a dinner with the help of an audio-visual-based IPA, namely Alexa Echo Show. Our study reveals ambiguous mental models of perceived and experienced device capabilities, leading to confusion. Meanwhile, the additional visual output channel could not counterbalance the weaknesses of voice interaction. Finally, we aim to illustrate users’ conceptual understandings of IPAs and provide implications to rethink audiovisual output for voice-frst standalone devices.

[BibTeX] [Abstract] [Download PDF]In both data protection law and research of usable privacy, awareness and control over the collection and use of personal data are understood to be cornerstones of digital sovereignty. For example, the European General Data Protection Regulation (GDPR) provides data subjects with the right to access data collected by organisations but remains unclear on the concrete process design. However, the design of data subject rights is crucial when it comes to the ability of customers to exercise their right and fulfil regulatory aims such as transparency. To learn more about user needs in implementing the right to access as per GDPR, we conducted a two-step study. First, we defined a five-phase user experience journey regarding the right to access: finding, authentication, request, access and data use. Second, and based on this model, 59 participants exercised their right to access and evaluated the usability of each phase. Drawing on 422 datasets spanning 139 organisations, our results show several interdependencies of process design and user satisfaction. Thereby, our insights inform the community of usable privacy and especially the design of the right to access with a first, yet robust, empirical body.

Tahir, A. (2022)Is Technology Necessary for Overcoming Anxiety: An Empirical Study
, Siegen
[BibTeX] [Abstract] [Download PDF]In this thesis I am focusing on how technology is helping students in overcoming anxiety, what technological artifacts students are using to deal with it. There is different coping mechanism to deal with anxiety. Some people prefer to be alone and some likes to surround them with friends and family. Most people experience anxiety depending on their surrounding or their experiences so to find out what are the reasons students’ experience anxiety I conducted semi-structured interviews. I collected data by asking participants about their general thoughts on anxiety, what are their opinions on dealing with anxiety with professional help and technological help, and in the end I asked them what future they envision in terms of anxiety. I conducted these interviews with students from diverse background to get their insights on what causes them anxiety and how they deal with it. Living alone, cultural shocks and managing studies are some of the reasons I got from interviews. When it comes to technological artifacts there are mobile applications and digital assistants available which helps in dealing with anxiety and I did market analysis on them too. For analyzing the data collected from interviews I did thematic analysis and from the results of the interview I created design fiction which propose the solutions to the problems faced by students.

CHI Conference on Human Factors in Computing Systems. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–15 doi:10.1145/3491102.3517435
[BibTeX] [Abstract] [Download PDF]Research on social robots in care has often focused on either the care recipients or the technology itself, neglecting the care workers who, in and through their collaborative and coordinative practices, will need to work with the robots. To better understand these interactions with a social robot (Pepper), we undertook a 3 month long-term study within a care home to gain empirical insights into the way the robot was used. We observed how care workers learned to use the device, applied it to their daily work life, and encountered obstacles. Our findings show that the care workers used the robot regularly (1:07 hours/day) mostly in one-to-one interactions with residents. While the robot had a limited effect on reducing the workload of care workers, it had other positive effects, demonstrating the potential to enhance the quality of care.

Researching political activism in Republika Srpska, we identified issues relating to the use of ICT and social media, leading to the redesign of our prototype which now raises awareness of privacy and security and supports activists by challenging ignorance, lowering exposure, and enabling remediation. We addressed “usable security” challenges to ensure simplicity of the tool and engaged with HCI researchers focused on international activism to assess the global applicability of the technical design.

[BibTeX] [Abstract] [Download PDF]This study observes, interprets, and analyses the knowledge production in the research field of Human–Robot Interaction (HRI). It intends to foreground the hidden assumptions that are often taken for granted when roboticist design and conduct their research. By doing so, this study demonstrates how these assumptions influence the result of their research. Based on data collected through sociological field observation, this study argues that the current practise in HRI research is highly anthropocentric. In short, the robots are designed to be like human instead of for human. Therefore, the human–robot relationship embodies the existing power relations between human beings. These relations generate inequality, hierarchy, and dominance, which are the opposite of the common imagination of the robotised future among roboticists. For the purpose of enabling the robotised future closer to their ideal, this study suggests that HRI researchers to go beyond the conventional methodology, to allow a human–robot relationship that realises reciprocity.

CHI ’22 Extended Abstracts. New Orleans, LA, USA, Publisher: Association for Computing Machinery, Pages: 6 doi:10.1145/3491101.3519676
[BibTeX] [Abstract]Technological objects present themselves as necessary, only to become obsolete faster than ever before. This phenomenon has led to a population that experiences a plethora of technological objects and interfaces as they age, which become associated with certain stages of life and disappear thereafter. Noting the expanding body of literature within HCI about appropriation, our work pinpoints an area that needs more attention, „outdated technologies. “ In other words, we assert that design practices can profit as much from imag-inaries of the future as they can from reassessing artefacts from the past in a critical way. In a two-week fieldwork with 37 HCI students, we gathered an international collection of nostalgic devices from 14 different countries to investigate what memories people still have of older technologies and the ways in which these memories reveal normative and accidental use of technological objects. We found that participants primarily remembered older technologies with positive connotations and shared memories of how they had adapted and appropriated these technologies, rather than norma-tive uses. We refer to this phenomenon as nostalgic reminiscence. In the future, we would like to develop this concept further by discussing how nostalgic reminiscence can be operationalized to stimulate speculative design in the present.

[BibTeX] [Abstract]The Octalysis framework is a gamification framework used for the design and evaluation of “human-focused” systems. Although several practitioners have applied it within their daily work, only a few academic articles have reflected on its applicability. With this study, we present how and where the framework is currently applied based on a large-scale literature study and reflect on the potentials and obstacles of using it within a Human Computer Interaction (HCI) master’s class. Our empirical findings show that the use of the Octalysis framework is often simplified and can also be overwhelming. The results further reveal that the framework itself can be helpful in the creation and evaluation of concepts, especially when extensive user research is not possible (e.g., due to time constraints). We contribute to the field of gamification by critically reflecting on the use of the Octalysis framework.

IN Journal of Responsible Technology, Pages: 32 doi:10.1016/j.jrt.2022.100029
[BibTeX] [Abstract] [Download PDF]Data protection risks play a major role in data protection laws and have shown to be suitable means for accountability in designing for usable privacy. Especially in the legal realm, risks are typically collected heuristically or deductively, e.g., by referring to fundamental right violations. Following a user-centered design credo, research on usable privacy has shown that a user-perspective on privacy risks can enhance system intelligibility and accountability. However, research on mapping the landscape of user-perceived privacy risks is still in its infancy. To extend the corpus of privacy risks as users perceive them in their daily use of technology, we conducted 9 workshops collecting 91 risks in the fields of web browsing, voice assistants and connected mobility. The body of risks was then categorized by 11 experts from the legal and HCI-domain. We find that, while existing taxonomies generally fit well, a societal dimension of risks is not yet represented. Discussing our empirically backed taxonomy including the full list of 91 risks, we demonstrate roads to use user-perceived risks as a mechanism to foster accountability for usable privacy in connected devices.

IN Zu treuen Händen? Verbraucherdatenschutz und digitale Selbstbestimmung, Vol. 6, Pages: 25
[BibTeX] [Abstract] [Download PDF]Der technische Fortschritt im Bereich der Erhebung, Speicherung und Verarbeitung von Daten macht es erforderlich, neue Fragen zu sozialverträglichen Datenmärkten aufzuwerfen. So gibt es sowohl eine Tendenz zur vereinfachten Datenteilung als auch die Forderung, die informationelle Selbstbestimmung besser zu schützen. Innerhalb dieses Spannungsfeldes bewegt sich die Idee von Datentreuhändern. Ziel des Beitrags ist darzulegen, dass zwischen verschiedenen Formen der Datentreuhänderschaft unterschieden werden sollte, um der Komplexität des Themas gerecht zu werden. Insbesondere bedarf es neben der mehrseitigen Treuhänderschaft, mit dem Treuhänder als neutraler Instanz, auch der einseitigen Treuhänderschaft, bei dem der Treuhänder als Anwalt der Verbraucherinteressen fungiert. Aus dieser Perspektive wird das Modell der Datentreuhänderschaft als stellvertretende Deutung der Interessen individueller und kollektiver Identitäten systematisch entwickelt.

IN Sustainability, Vol. 14, Pages: 4148 doi:10.3390/su14074148
[BibTeX] [Abstract] [Download PDF]As the population ages, the question of how to prevent isolation among older people and increase their well-being becomes a social issue. It has often been argued that Information and Communication Technology (ICT) usage can be a solution to these challenges, but empirical studies have not shown consistent results. Moreover, there are even fewer studies targeting older people in Japan, which is the most aging country in the world. Therefore, using the psychological comprehensive data of Japanese people aged 60 and over recorded in World Values Survey Wave 7, we conducted a study to clarify the relationship between the ICT usage, social capital, and well-being of older people to make a meaningful contribution to policymakers and the scientific community. As a result of the analysis, it was shown that ICT usage indirectly enhances well-being by increasing social capital. This indicates that for older people, ICT usage does not have a large effect on enhancing well-being, but becomes sufficiently large only through the improvement of social capital. The pros and cons of such modern communication means should be utilized as a reference when considering the development of future communication means and a human coach—a person who supports the use of communication means by older people. In other words, to think about the spread of communication means to community-dwelling older people in the future, it is always necessary to think about technology usage emphasizing the relationship between older people and society.

[BibTeX] [Abstract] [Download PDF]An extensive literature on participatory design with older adults has, thus far, little to say about the support older adults need when involved in online activities. Our research suggests that to empower older adults in participatory design, scaffolding work has to be done. Scaffolding interactions – creating temporary instructional support to help the learning of participants – is a common approach in participatory design. Yet, when applied in online participatory design with older adults, the traditional understanding of the concept does not match the way older adults‘ learn. Hence, we argue for a new understanding of this term, which we call situated scaffolding. We illustrate our argument with a case where older adults collaborate online as part of a participatory design project. We unpack the different dimensions of situated scaffolding and discuss how this novel understanding can be used to further inform sustainable participatory design for and with older adults.

[BibTeX] [Abstract] [Download PDF]Digital literacy refers to a set of competencies related to the skilled use of computers and information technology. Low digital skills can be a barrier for older adults’ full participation in a digital society, and COVID-19 has increased this risk of social exclusion. Older adults’ digital inclusion is a complex process that consists of the interplay of structural and individual factors. The ACCESS project unwrapped the complexity of the process and developed an innovative, multilevel model that illustrates how societal, institutional, material and pedagogical aspects shape adults’ appropriation of digital literacy. A holistic model describes factors contributing to older adults’ digital literacy, acknowledging sociocultural contexts, environments, learning settings and instruction practices for learning digital literacy. Instead of seeing older adults’ reasons for learning digital skills purely as individual choice, this model recognizes the interpersonal, institutional and societal aspects that implicitly or explicitly influence older adults’ acquisition of digital literacy. The results offer a tool for stakeholders, the research community, companies, designers and other relevant stakeholders to consider digital skills and the given support. It demands diverse communication between different stakeholders about the things that should be discussed when organizing digital support in digitalized societies.

[BibTeX] [Abstract] [Download PDF]The use of social media today is not only ubiquitous and an integral part of everyday life but is also increasingly relevant before, during, or after emergencies. Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies. This chapter presents the social media API (SMA), which is a multi-platform service for gathering big social data across different social media channels and analyzing the credibility and relevance of collected data by the means of machine learning models. Based on the lessons learned from both the implementation process and user-centered evaluations in multiple emergency settings, this chapter discusses core challenges and potentials of the SMA and similar services, focusing on (1) the multi-platform gathering and management of data, (2) the mitigation of information overload by relevance assessment and message grouping, (3) the assessment of credibility and information quality, and (4) user-centered tailorability and adjustable data operations.

[BibTeX] [Abstract] [Download PDF]Intercultural studies are scarce but yet insightful to better understand reactions of older adults to human-like Android robot behavior. They help to see which reactions of participants are universal and which are country specific. Research with android robots and older adults has many results that are based on online research with pictures or on research that has been carried out in labs in one country. Within a Japanese-European research project, we had the rare occasion to work with an android robot in both countries and compare the results. We collected data from 19 participants that were invited in a Living Lab at two universities in Japan and Germany. The data contains interviews, videos and questionnaires and was analyzed with a mixed method approach. Results indicate that the android robots of this study are not in the valley of the uncanny valley theory. We could observe that the older adults and stakeholders from both countries were open to talk to the robot, some even about private topics, while others preferred to use the robot to retrieve information. German participants wished for more gestures, while Japanese participants were keen on the relatively little number of gestures. With this work we contribute to a broader understanding on how older adults perceive android robots and could show that an android robot with its human-like appearance is not seen as uncanny.

Within a Japanese-European research project, we had the rare occasion to work with an android robot in both countries and compare the results. We collected data from 19 participants that were invited in a Living Lab at two universities in Japan and Germany. The data contains interviews, videos and questionnaires and was analyzed with a mixed method approach. Results indicate that the android robots of this study are not in the valley of the uncanny valley theory. We could observe that the older adults and stakeholders from both countries were open to talk to the robot, some even about private topics, while others preferred to use the robot to retrieve information. German participants wished for more gestures, while Japanese participants were keen on the relatively little number of gestures. With this work we contribute to a broader understanding on how older adults perceive android robots and could show that an android robot with its human-like appearance is not seen as uncanny.}, language = {en}, booktitle = {Social {Robotics}}, publisher = {Springer Nature Switzerland}, author = {Carros, Felix and Bürvenich, Berenike and Browne, Ryan and Matsumoto, Yoshio and Trovato, Gabriele and Manavi, Mehrbod and Homma, Keiko and Ogawa, Toshimi and Wieching, Rainer and Wulf, Volker}, editor = {Cavallo, Filippo and Cabibihan, John-John and Fiorini, Laura and Sorrentino, Alessandra and He, Hongsheng and Liu, Xiaorui and Matsumoto, Yoshio and Ge, Shuzhi Sam}, year = {2022}, keywords = {Older adults, Appropriation, Ethnography, HRI, Wizard-of-Oz, Android robot, Assisted living, Living lab, NLP, Self-disclosure, Social robot, Uncanny valley}, pages = {574--586}, } -

[BibTeX] [Abstract]Soft robots provide the opportunity to handle a diverse range of products, contributing to mass customization in modern production environments. Both, their manufacturing and behavioral modelling are crucial challenges, due to their unique, bio-inspired design, as well as with respect to the elastic materials, which are applied. Commonly, the actuators and grippers of these robots are manufactured in a traditional casting approach, which is both elaborate and requires molding clearances. In this paper, the additive manufacture (AM) of thermoplastic polyurethane (TPU) is investigated in the context of its application as soft robotic components. Compared to other elastic AM materials, TPU reveals superior mechanical properties with regard to strength and strain. By selective laser sintering, pneumatic bending actuators (pneu-nets) are 3D printed as soft robotic case study and experimentally evaluated with respect to deflection over internal pressure. Leakage due to air tightness is observed as a function of minimum wall thickness of the actuators. In an automated production environment, soft robotics can complement the transformation of rigid production systems towards agile and smart manufacturing.

This work investigates whether the graphical approaches (e.g., using RAFCON) yield a better real-time simulation or not compared to agent approaches (e.g., using MOSIM-AJAN).

[BibTeX] [Abstract]In virtual production planning, simulating human motions helps to improve process planning and interaction efficiency. However, simulating multiple humans sharing tasks in a shared workplace requires understanding how human workers interact and share autonomy. In this regard, an Inertial Measurement Unit based motion capture is employed for understanding shifting roles and learning effects. Parameters such as total time, distance, and acceleration variances in repetition are considered for modeling collaborative motion interactions. The results distinguish motion patterns versus the undertaken interactions. This work may serve as an initial input to model interaction schemes and recognize human actions behavior during team assembly. Furthermore, the concept can be extended toward a human-robot shared autonomy.

[BibTeX] [Abstract]Snap joints provide the opportunity of joining two components in a very simple, economical and rapid way. Therefore, snap joints are a feasible option for assembly of prototypes. Snap joint design guidelines currently focus on injection-molded parts, which may not be suitable for rapid prototyping. In contrast to injection molding, additive manufacturing provides a higher degree of design freedom. Applicability of design guidelines for injection-molded snap joints to additive manufacturing technologies has not been comprehensively investigated yet. In this work, we present a study comparing mechanical properties of snap joint specimen that are manufactured from three different materials with the two manufacturing processes FDM and SLS. Results show significant impact of both material and manufacturing technology. The presented results may lead to improved design guidelines for additively manufactured snap joints.

doi:10.48340/ecscw2022_n04
[BibTeX] [Abstract] [Download PDF]In this paper, we reflect on the experiences from two Grounded Design (GD) research projects conducted by a multidisciplinary group of researchers between 2019 – 2021 and highlight the methodological foundations and related obstacles for iterative designing. Both projects investigate the phenomena of knowledge sharing and crisis-related learning in business organizations under the GD paradigm, which has been increasingly adopted within the Computer- supported Cooperative Work (CSCW) community. During these projects, the researchers with backgrounds in computer science, business informatics, software engineering, and sociology experienced the need for systematization to transition between the stages of GD. Looking back, we realize that our teams arrived at this systematization by blending the prior knowledge from team members’ original educational backgrounds. While blending practices most likely happens intuitively in interdisciplinary projects, as is often the case of the user-centered design initiatives seen in CSCW and Human-Computer Interaction, little can be found on how this usually happens and its implications. In this paper, we respond to this literature gap by discussing how this blending can facilitate the realization of GD projects and lead to a praxeological information science research perspective, which has ‘methods appropriation’ as key to systematizing abstraction, broader traceability, and flexibility of research methods.

Alizadeh, F., Stevens, G., Vereschak, O., Bailly, G., Caramiaux, B. & Pins, D. (2022)Building Appropriate Trust in Human-AI Interactions
doi:10.48340/ecscw2022_ws04
[BibTeX] [Abstract] [Download PDF]AI (artificial intelligence) systems are increasingly being used in all aspects of our lives, from mundane routines to sensitive decision-making and even creative tasks. Therefore, an appropriate level of trust is required so that users know when to rely on the system and when to override it. While research has looked extensively at fostering trust in human-AI interactions, the lack of standardized procedures for human-AI trust makes it difficult to interpret results and compare across studies.

[BibTeX] [Abstract] [Download PDF]Learning is inherently social. This raises several questions that relate to how contexts and spaces can mediate co-creative learning. In this workshop proposal, we refer to the interrelated aspects of space, learning, and embodiment and how these aspects mediate the human-robot interaction. Our assumption is that robots are interpreted variously and used in different ways. We are interested in the interrelation between interpretation and use, which are constitutive for the establishment of different co-creative learning spaces. Reflecting on this leads to an understanding of what to look for in Participatory Design studies. It matters, for example, whether persons in a nursing home have any say at all in how robots are perceived and in what technical practices robots are to be integrated and adopted. This is a crucial aspect for the appropriation of technical artifacts and for the development of new (E)CSCW or HCI paradigms.

In order to fulfill requirements of the villages, which were identified in citizen workshops together with local stakeholders, a selection procedure was carried out and the decision was made to use an already existing and known neighborhood platform. We demonstrate the challenges posed by the fact that the platform was not actually designed for the specific requirements of rural villages, but for larger cities or urban areas, so that various processes of adaptation and implementation had to be carried out. We reflect trade-offs and negotiations between research-led and community-oriented demands in the introduction and adaptation phase of the neighborhood platform in respect to usage motivations and roles of local stakeholder groups.

[BibTeX] [Abstract] [Download PDF]This work presents a prototype for a multimodal and augmented (AR) based System designed for individual and joint activities in outdoor sports. Based on the need for social interaction and computer-supported collaborative sports and the decreasing physical activity across all ages, game scenarios for the context of outdoor sports were formulated and implemented with a head-worn multimodal AR interface. The System’s innovation, flexibility, and multimodality found the basis for multiple use cases, such as professional and leisure, individual and group contexts. The technical infrastructure allows multimodal experiences while tracking and monitoring data such as movement speed, location, and heart rate. Within several game scenarios, players can cooperatively and competitively challenge themselves and other players to improve their physical activity playfully.

[BibTeX] [Abstract] [Download PDF]Over the past two decades, the business model of surveillance capitalism has emerged in the IT industry. This model has turned out to be highly profitable, but, if left unchecked, will very likely undermine the foundations of liberal democracies and quality of life on this planet. It involves customized advertising and behavior manipulation, powered by intensive gathering and cross-correlation of personal information. There are significant indirect costs of this model, including loss of privacy, supporting surveillance by both the state and corporations, undermining the democratic process, other kinds of automated attempts of behavior manipulation, and excessive consumerism with its attendant environmental costs. Turning to what could be done, we propose a co-development of regulation and technology, as well as the key roles that can be played by citizens and civil society organizations. The regulatory measures are intended to safeguard privacy, require true informed consent, and to foster interoperability (even among rival firms, nonprofit organizations, and others). We also identify key enabling technologies, including open source, APIs to support interoperability and portability, encryption, and peer-to-peer systems. Finally, we discuss the crucial role of ownership structures for these IT services and argue for an ecosystem approach as a counter narrative to surveillance capitalism.

[BibTeX] [Abstract] [Download PDF]Over the last decades, different kinds of design guides have been created to maintain consistency and usability in interactive system development. However, in the case of spatial applications, practitioners from research and industry either have difficulty finding them or perceive such guides as lacking relevance, practicability, and applicability. This paper presents the current state of scientific research and industry practice by investigating currently used design recommendations for mixed reality (MR) system development. We analyzed and compared 875 design recommendations for MR applications elicited from 89 scientific papers and documentation from six industry practitioners in a literature review. In doing so, we identified differences regarding four key topics: Focus on unique MR design challenges, abstraction regarding devices and ecosystems, level of detail and abstraction of content, and covered topics. Based on that, we contribute to the MR design research by providing three factors for perceived irrelevance and six main implications for design recommendations that are applicable in scientific and industry practice.

Esau, M., Lawo, D., Castelli, N., Jakobi, T. & Stevens, G. (2021)Morning Routines between Calm and Engaging: Designing a Smart Mirror
, Publisher: SciTePress, Science and Technology Publications, Pages: 58–69
[BibTeX] [Abstract] [Download PDF]Frequently the main purpose of domestic artifacts equipped with smart sensors is to hide technology, like previous examples of a Smart Mirror show. However, current Smart Homes often fail to provide meaningful IoT applications for all residents’ needs. To design beyond efficiency and productivity, we propose to realize the potential of the traditional artifact for calm and engaging experiences. Therefore, we followed a design case study approach with 22 participants in total. After an initial focus group, we conducted a diary study to examine home routines and developed a conceptual design. The evaluation of our mid-fidelity prototype shows, that we need to study carefully the practices of the residents to leverage the physical material of the artifact to fit the routines.

To design beyond efficiency and productivity, we propose to realize the potential of the traditional artifact for calm and engaging experiences. Therefore, we followed a design case study approach with 22 participants in total. After an initial focus group, we conducted a diary study to examine home routines and developed a conceptual design. The evaluation of our mid-fidelity prototype shows, that we need to study carefully the practices of the residents to leverage the physical material of the artifact to fit the routines.

IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-021-09401-8
[BibTeX] [Abstract] [Download PDF]This paper describes the appropriation processes involved in establishing a socio-technical enabling infrastructure in a valley in the High Atlas of Morocco. We focus on the challenges of co-establishing such an intervention in a rural/mountainous region that is already undergoing a process of continuous development and profound transformation. We reflect upon the changes and unforeseen appropriation by our local partners and inhabitants in the valley of a computer club primarily used as an informal learning centre for school children. We followed an ethnographic approach and combined research perspectives from both socio-informatics and anthropology. This paper sheds light on what a successful cooperation and intervention in this kind of challenging environment can look like. It does this by taking seriously competing expectations, fragile infrastructural foundations and the socio-cultural context. Despite the challenges, the intervention managed to lead to the establishment of a socio-technical enabling infrastructure that plays a particularly valuable role in local educational endeavours and that is now moving towards supporting other members of the community. The paper thus provides insights regarding what has to be considered to create a mutually beneficial cooperation with all relevant stakeholders as well as a sustainable intervention.

, Publisher: SciTePress, Science and Technology Publications, Pages: 36–47
[BibTeX] [Abstract] [Download PDF]With the debates on climate change and sustainability, a reduction of the share of cars in the modal split has become increasingly prevalent in both public and academic discourse. Besides some motivational approaches, there is a lack of ICT artifacts that successfully raise the ability of consumers to adopt sustainable mobility patterns. To further understand the requirements and the design of these artifacts within everyday mobility adopted a practice-lens. This lens is helpful to get a broader perspective on the use of ICT artifacts along consumers’ transformational journey towards sustainable mobility practices. Based on 12 retrospective interviews with car-free mobility consumers, we argue that artifacts should not be viewed as ’magic-bullet’ solutions but should accompany the complex transformation of practices in multifaceted ways. Moreover, we highlight in particular the difficulties of appropriating shared infrastructures and aligning own practices with them. This opens up a design space to provide more support for these kinds of material-interactions, to provide access to consumption infrastructures and make them usable, rather than leaving consumers alone with increased motivation.

However, this research does not go beyond the conceptualization of such systems. Therefore, there is a deficit in understanding how to combine different services and data sources and which design challenges arise from building integrated Household Information Systems. In this paper, we probed the design of an Integrated Household Information System with 13 participants. The results point towards more personalization, automatization of storage administration and enabling flexible artifact ecologies. Our paper contributes to understanding the design and usage of Integrated Household Information Systems, as a new class of information systems for HCI research.

IN International Journal of Environmental Research and Public Health, Vol. 18, Pages: 11800 doi:10.3390/ijerph182211800
[BibTeX] [Abstract]Skills, knowledge, and awareness of digital and technological tools are essential to improve the state of well-being and health of older adults and also to mitigate the condition of social isolation in the aging process. For this reason, it is necessary to implement a social learning of electronic/digital tools for health of older people to support the achievement of eHealth and digital competences. The paper reports the results of an Italian innovative eHealth training for the European project ACCESS. The training has been based on blended didactical and interactive educational techniques, aimed at collecting as many points of view as possible from older adults. A total of 58 older adults were recruited to attend a four-week training program, which included five modules. The results showed a statistical significant difference between the eHealth Literacy Scale (eHEALS) mean value before and after the course. A significant negative correlation was found between eHEALS and positive/total Survey of Technology Use (SOTU), suggesting an inverse relationship between positive/total SOTU and eHEALS. There is a strong positive and statistically significant relationship between satisfaction with the training and eHEALS. The results indicate that the intervention increased the digital competences of participants connected to health.

, Publisher: ACM doi:10.1145/3476050
[BibTeX] [Abstract]An increasing number of people around the world are forced to leave their homes due to the climate catastrophe, regional conflict or poverty. In their new host countries however, refugees and migrants are frequently met by a wide range of challenges, including wider societal participation. The difficulties migrants and refugees face have also increasingly become the topic of HCI and CSCW work. In this paper we report on a three year-long project, involving refugees, migrants and activist supporters in a co-design project to develop tools that aid the process of resettling. Several aspects have challenged equal participation in the project, including divergent motives, unequal power distribution and cultural heterogeneity. Despite these challenges the project outcomes are in use and maintained beyond the project runtime through voluntary actors. We reflect on this discrepancy between process and outcome drawing on the concept of care.

[BibTeX] [Abstract] [Download PDF]A variety of studies exist that design innovative interactions based on augmented reality (AR). Comparing them often involves examining their laboratory studies. However, since AR has a high context dependency (e.g., reference to the real environment), it is important to emphasize that existing literature do not reveal generalizable results regarding how to design AR instructions. Within this paper, we argue that it is time to open up new use cases and test appropriation mechanisms in practice with the help of long-term studies to build a base for the comparison of AR-based interactions. Such a repository built up with long-term studies has the potential to define valid insights for future developments in the AR environment.

Using the concept of social capital as a framework, we investigate the intersection between the use of digital tools and developing cultural and economic practices among these groups during this transitional period. Reflecting on the bonding and bridging aspects of social capital, we describe how ex-combatants draw on substantial social capital from their former lives as a guerrilla army in order to strengthen their position in these new circumstances, and their cautious and difficult creation of new social ties with wider Colombian society. We contribute to the CSCW discourse by discussing the crucial role digital tools, previously not available to these groups, play in sustaining, re-growing and building social capital of communities in post-conflict periods.

Weber, J. K. (2021)Design of an Interaction Concept for Assisted Cooking in Smart Kitchens
, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]Cooking can be a complex activity that concerns almost everyone in everyday life. Therefore, the topic of smart kitchens has great potential to provide users with added value through intelligent assistance. However, so far there is a lack of user-centric and holistic concepts for the use of these technologies in the cooking context. This shows the need to understand how users can be supported by integrating multiple devices in an interaction concept for assisted cooking. Therefore, the aim of this thesis is to design an interaction concept for assisted cooking in smart kitchens. The design mainly considers which interaction modalities are suitable and what aspects are relevant for designing a multimodal interaction concept. Furthermore, it is investigated in which form an intelligent assistant can proactively support the user during a cooking process. It is a target to investigate how the personality of the user, especially the factors cooking competence and need for autonomy, can affect the perception of such a proactive assistant. To achieve this goal, two qualitative studies were designed conducted using the user-centered design process. In order to understand the user context of cooking with a focus on cooking alone, a participant observation was conducted. Based on this, a multimodal proactive interaction concept was designed considering design guidelines from the literature. Finally, the concept was evaluated in the form of the prototype ”Cookie” using a Wizard-of-Oz approach. The conducted studies included different user groups recruited with a questionnaire designed for this purpose. The results of the thesis provide design indications for multimodal proactive assistants. Accordingly, for the design of multimodal systems it is especially important to consider the application context and the interaction efficiency. Furthermore, the modalities should be designed to be complementary to each other in a combined design process to achieve a holistic concept. For the design of proactive assistants, an emphasis should be put on the accuracy of user intention recognition in order to be able to support users according to their needs. Regarding proactivity, the results show that the degree of user involvement in the cooking activity can influence the users’ perception of the assistant’s controllability. Moreover, different user groups indicate to have different expectations towards the assistant to be perceived as trustworthy. In addition, the personality characteristics of cooking competence and need for autonomy might have an impact on the user’s perception of decision freedom when using a proactive assistant. Directions are provided towards further research focusing on how an adaptive proactive assistant could adapt to the user’s personality.

Li, Q. (2021)Learning from the Past – The Use of Secondary Qualitative Material in a Design Education Context
, Siegen, Germany
[BibTeX] [Abstract] [Download PDF]In this thesis, I examine the use of qualitative data drawn from existing project material as a resource for design education. The use of second-hand qualitative data has been discussed extensively in relation to the ‘open science’ agenda, but its use as an educational resource has not. To investigate the extent to which second-hand qualitative data might be useful for analytic work, I conducted a study in which students were encouraged to use Grounded Design – a usercentred design approach in Siegen Social Informatic group- as a means to leverage data of this kind. Four design seminars were carried out to allow Master’s students participating in an HCI program access to substantial datasets collected in two long-term research projects that had finished some time previously. In the first seminar, the students were asked to select content from this dataset, analyse it, and then, on the basis of this, form conclusions about possible design opportunities. The study reveals a number of challenges and insights regarding what it takes to use qualitative data as a resource for design. After that, I involved students in the second and third seminar in the design process of preparing the secondary research data, namely designing tools and curating data. An artefact called DesignCaser was developed, and later, tested by the fourth seminar students. The evaluation of the processes undergone revealed both that students saw the exercise as useful and illuminating with respect to their understanding of how qualitative material can be used for design purposes but also, at the same time demonstrated some of the challenges involved. These were primarily to do with the amount of material, how it was curated, the nature of the data, and the time available to them.

In the first seminar, the students were asked to select content from this dataset, analyse it, and then, on the basis of this, form conclusions about possible design opportunities. The study reveals a number of challenges and insights regarding what it takes to use qualitative data as a resource for design. After that, I involved students in the second and third seminar in the design process of preparing the secondary research data, namely designing tools and curating data. An artefact called DesignCaser was developed, and later, tested by the fourth seminar students. The evaluation of the processes undergone revealed both that students saw the exercise as useful and illuminating with respect to their understanding of how qualitative material can be used for design purposes but also, at the same time demonstrated some of the challenges involved. These were primarily to do with the amount of material, how it was curated, the nature of the data, and the time available to them.}, language = {en}, school = {University of Siegen}, author = {Li, Qinyu}, month = sep, year = {2021}, keywords = {Dissertation}, } -
Struzek, D., Butorac, J. & Mueller, C. (2021)Designing for older dancers – implications for design of IT which supports joy of movement in urban spaces
Gemeinsame Fachtagung der DGGG: „(Neue) Lebensformen im Alter“. doi:10.13140/RG.2.2.25446.34882
[BibTeX] [Abstract]The current global pandemic caused by COVID-19 has turned many people’s daily lives upside down. The scale of the crisis forced countries to take increasingly drastic measures, from initial hygiene and protection measures to a complete lockdown of public and private life. To this end, public places were closed off, large events were banned for the time being, and public offerings and activities that lead to gatherings of people were not permitted. Older adults, as a particularly vulnerable group, suffer from the physical distancing measures when they have to reduce social activities. To bridge the physical distance problem, videoconferencing and live streaming solutions have gained popularity. The poster demonstrates research activities from the BMBF-funded “Active City Innovation” research project, exploring how dance and movement in public spaces can be supported by socio-technical systems with a special focus on older citizens. As part of the requirements analysis process, interviews and participant observations have been conducted with older dancers between 65 and 95 years in Siegen. The dance group had been meeting regularly to dance together for several years. Due to the COVID-19 restrictions, they had to cancel all joint dance activities on site. With the qualitative research approach, we aim to understand the motivations of the older dancers as well as their trainers and extrapolate implications for potential technical assistance from the findings. The results indicate that dancing, especially among older adults, is not comparable to other physical activities and that personal exchange and a sense of community are the main reasons for participation at the dance class. Digital solutions such as live streaming solutions are hardly seen as an alternative to exercise and tend to be rejected, since technical systems are not associated with leisure time and, above all, cannot convey the human feeling of the joint activity. The results also show that dancing or moving in a group provides support and structure in the living environment and is seen as a movement option especially by women, while men prefer other sportive activities, such as riding a bicycle. Our results may assist researchers and developers in implementing conferencing and live streaming systems to support physical activity promotion in older adults, and most importantly, raise awareness of social participation and sense of community as key motivators for using such systems.

[BibTeX] [Abstract] [Download PDF]Nowadays, recommender systems are a fundamental part of several online services. However, most of these systems rely on collective user data and ratings or a preselection of parameters to derive appropriate recommendations. Within this paper, we examine recommendations without previous user data. We therefore designed and evaluated a knowledge-based recommender system by turning to recipe recommendations that offer alternatives for favorite recipes. We introduce and compare three versions of a given algorithm. Our evaluation shows that the knowledge-based approach may serve as a good start for deriving appropriate recommendations without prior user data. Moreover, we show that end-users’ assumptions about decisive criteria of a recommender system do not necessarily match the later actual decisive criteria.

Conducting interviews with German taxi drivers, we investigate how they perceive the changes caused by advancing automation for the future of their business. Our study contributes insights into how the work of taxi drivers could change given the advent of autonomous driving: While the task of driving could be taken over by SAVs for standard trips, taxi drivers are certain that other areas of their work such as providing supplementary services and assistance to passengers would constitute a limit to such forms of automation, but probably involving a shifting role for the taxi drivers, one which focuses on the sociality of the work. Our findings illustrate how taxi drivers see the future of their work, suggesting design implications for tools that take various forms of assistance into account, and demonstrating how important it is to consider taxi drivers in the co-design of future taxis and SAV services.

Struzek, D. & Mueller, C. (2021)Introduction of a platform for fostering social participation and engagement in rural areas
Gemeinsame Fachtagung der DGGG: „(Neue) Lebensformen im Alter“. doi:10.13140/RG.2.2.32157.23526
[BibTeX] [Abstract]Rural areas are struggling with ever greater challenges. Young people are leaving, social spaces are disappearing, and public infrastructure is poor or lacking. Various technical communication channels are already being used to provide support. This has led to information overload and a lack of trust in new technologies, especially among the older population. In order to support 6 villages in mutual communication, we used the well-known neighborhood platform „nebenan.de,“ which was developed for urban areas, as part of the 3-year research project Digital Village Center (Digi.DoM), which focused on developing digitization strategies for rural areas. Older residents in particular should have a way to get help from others, post questions about technology, requests or offers for sale, and requests for rides, even across villages. Participatory approaches were used to identify requirements for the platform for rural areas. Appropriation of the platform took place in 6 technology workshops held in three villages. Although residents of all ages were welcome, only residents between the ages of 60 and 85 attended. The workshops helped us capture related needs of older users. To encourage interaction, a common group was created on the platform, accessible to all registered villagers from all villages. The meetings showed how hesitant the older users of the platform were and for the most part only surveyed the association work. In addition, the villages wished to have their own groups, to which other villages did not have access. Another problem was the lack of trust building, which was reflected in the fact that workshop participation decreased and participants were skeptical even about a list of participants. Significant, at the same time, was the village history, which was even seen as a reason for using the platform. Using the introduction process of nebenan.de as an example, the contribution reflects on a basic conflict of community technologies for the target group of older adults who have little experience with such applications. On the one hand, such community technologies only work if a sufficiently large mass of users participates („critical mass“). On the other hand, this is countered by worries of „non-users“ who are concerned with questions of security, privacy related to community processes, they are used to in their small village life. The poster shows how socially acceptable solutions were sought with the older people in negotiation processes.

Adjunct Publication of the 23rd International Conference on Mobile Human-Computer Interaction. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–6
[BibTeX] [Abstract] [Download PDF]Developing toolkits as a support of participatory design is a common approach when designing with and for older adults. The key aspect in designing digital tools is digital literacy of the participants and how to sustain it during the project but also after its end. Yet, not enough attention has been paid to how to use such toolkits to make PD projects results sustainable. To address this issue, we are developing a mobile demo-kit, a set of didactic prototypes, which aims to foster older participants’ digital literacy and hence make findings sustainable. We illustrate it on a practice-based study, during which we conducted participatory observation, a series of interviews and organized a series of participatory workshops online with older adults. Our preliminary findings contribute to discussion on making PD with and for older adults sustainable by focusing on what older adults can learn during the PD, how to support this process but also how to communicate the findings further on.

[BibTeX] [Abstract] [Download PDF]Due to the change from mass production to mass personalized production and the resulting intrinsic product flexibility, the automotive industry, among others, is looking for cost-efficient and resource-saving production methods to combining global just-in-time production. In addition to geometric manufacturing flexibility, additive manufacturing offers a resource-saving application for rapid prototyping and small series in predevelopment. In this study, the FDM process is utilized to manufacture the tooling to draw a small series of sheet metal parts in combination with the rubber pad forming process. Therefore, a variety of common AM polymer materials (PETG, PLA, and ABS) is compared in compression tests, from which PLA is selected to be applied as sheet metal forming die. For the rubber pad forming process, relevant processing parameters, i.e., press force and rubber cushion hardness, are studied with respect to forming depth. The product batch is examined by optical evaluation using a metrological system. The scans of the tool and sheet metal parts confirm the mechanical integrity of the additively manufactured die from polymer and thus the suitability of this approach for small series in sheet metal drawing processes, e.g., for automotive applications.

[BibTeX] [Abstract] [Download PDF]Since stationary self-checkout is widely introduced and well understood, previous research barely examined newer generations of smartphone-based Scan&Go. Especially from a design perspective, we know little about the factors contributing to the adoption of Scan&Go solutions and how design enables consumers to take full advantage of this development rather than being burdened with using complex and unenjoyable systems. To understand the influencing factors and the design from a consumer perspective, we conducted a mixed-methods study where we triangulated data of an online survey with 103 participants and a qualitative study with 20 participants. Based on the results, our study presents a refined and nuanced understanding of technology as well as infrastructure-related factors that influence adoption. Moreover, we present several implications for designing and implementing of Scan&Go in retail environments.

, Publisher: SCITEPRESS – Science and Technology Publications, Pages: 25–36
[BibTeX] [Abstract] [Download PDF]In the course of growing online retailing, recommendation systems have become established that derive recommendations from customers’ purchase histories. Recommending suitable food products can represent a lucrative added value for food retailers, but at the same time challenges them to make good predictions for repeated food purchases. Repeat purchase recommendations have been little explored in the literature. These predict when a product will be purchased again by a customer. This is especially important for food recommendations, since it is not the frequency of the same item in the shopping basket that is relevant for determining repeat purchase intervals, but rather their difference over time. In this paper, in addition to critically reflecting classical recommendation systems on the underlying repeat purchase context, two models for online product recommendations are derived from the literature, validated and discussed for the food context using real transaction data of a German stationary food retailer.

Digitalization and improving quality of live in rural and industrialized regions is a transformative, yet complex process, that depends inherently on the ability of regions to face challenges in modernizing their industrial base, upgrading the skills of the workforce, compensating for job losses in key sectors, enhance well-being and living standards and improve their contribution to national performance and more inclusive and resilient societies.

[BibTeX] [Abstract] [Download PDF]Developing systems to support remote collaboration usually involves creating new environments in which non-co-located participants produce actions that are, at least in part, accessible to one another. However, this typically fractures the relationship between those actions and the sense of a shared environment, engendering difficulties that can render even the simplest of activities problematic. This becomes more pronounced as the activities become more complex and involve physical artifacts. Although mixed reality seems to offer promising ways of overcoming these troubles, there is still a risk of replicating the fractured ecology problem. We report on an empirical study and the development of a mixed reality prototype called BeamLite that seeks to bypass such issues by providing participants with the illusion of them sharing a single familiar place. Although our evaluation revealed possibilities for evading some troubles associated with artifact-focused remote collaboration, it exposed the need for virtual toolboxes that dynamically support specific work practices and the importance of virtual artifacts embedded within the physical environment to further diminish the sense of ecological fracture.

[BibTeX] [Abstract] [Download PDF]Over the past several decades the concept of smart cities has gained a lot of attention amongst researchers, the media, governments, civic groups and citizens. The literature shows that innovations have a more positive impact when they stimulate the development of cities and shape their space for a variety of participants, or when design is participatory. This ensures a non-technocratic approach, i.e., one that builds on the complexity of today’s socio-technical systems and the consideration of their individual actors. Citizen-based approaches or one of the so-called Caring Community are possible answers to this. In this Design Fiction workshop, we take a critical view on the idea of smart cities by broadening participation to stakeholders who are still excluded from its concept and can be described as vulnerable and often marginalized, such as people who are (culturally) diverse (e.g. migrants, refugees, older adults, children, currently and formerly incarcerated people, homeless people and those with low income) or neurodiverse (e.g. people living with mental health challenges as autism or dementia or who suffer from functional impairments), and also animals and nature who are left behind in the whole digitization process. In this regard we will also address topics like sustainability and well-being. One of the expected outcomes of this workshop is the development of a holistic and sustainable smart city concept involving currently excluded stakeholders.

By making the collected data explorable for consumers, our research-through-design approach seeks to unveil design resources for fostering data literacy and help users in making better informed decisions regarding their use of VAs. In this paper, we present the design of an interactive prototype that visualizes the conversations with VAs on a timeline and provides end users with basic means to engage with data, for instance allowing for filtering and categorization. Based on an evaluation with eleven households, our paper provides insights on how users reflect upon their data trails and presents design guidelines for supporting data literacy of consumers in the context of VAs.

Weber, P., Krings, K., Nießner, J., Brodesser, S. & Ludwig, T. (2021)FoodChattAR: Exploring the Design Space of Edible Virtual Agents for Human-Food Interaction
Designing Interactive Systems Conference 2021. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 638–650 doi:10.1145/3461778.3461998
[BibTeX] [Abstract] [Download PDF]There has been recent criticism from researchers towards simple replication of traditional role models in the design of virtual agents and robots, and a call for new forms of interaction and communication with technology. By exploring the field of Human-Food interaction (HFI) – a sub-area of Human-Computer Interaction (HCI) which aims to investigate the diversity of ways people interact with food – we therefore specifically examine the design space of edible anthropomorphic virtual agents (EAVAs). To understand human-to-food interactive communication, we conducted an interview study with 19 participants, followed by a co-design workshop on the design of conversational agents for personified food. Based on the results, we implemented a prototype called FoodChattAR that employs augmented reality and chatbots to interact and communicate with food.

By exploring the field of Human-Food interaction (HFI) – a sub-area of Human-Computer Interaction (HCI) which aims to investigate the diversity of ways people interact with food – we therefore specifically examine the design space of edible anthropomorphic virtual agents (EAVAs). To understand human-to-food interactive communication, we conducted an interview study with 19 participants, followed by a co-design workshop on the design of conversational agents for personified food. Based on the results, we implemented a prototype called FoodChattAR that employs augmented reality and chatbots to interact and communicate with food. Our evaluation with 21 participants shows that FoodChattAR turns eating into fun, while at the same time the food conveys relevant societal facts about itself.

[BibTeX] [Abstract] [Download PDF]Most participation processes in urban planning offer poor incentives, especially for young citizens, hence important citizen’s needs are excluded. Our work aims at identifying the degree to which Augmented Reality (AR) might motivate young people. We developed an AR-app with Unity3D to create new interaction concepts for use cases in urban planning. Building projects and environment changes are visualized, so citizens can contribute design ideas to the process. Using a human-centered design approach, we invited different stakeholders to participate. We conducted 40 interviews and a survey, then interaction concepts were evolved by citizens in four participatory design workshops. Our findings show that AR can motivate increased participation in urban planning. We also demonstrate a new approach to engaging low-tech users in designing high-tech solutions such as AR systems by using haptic 3D-tools like Lego or clay. Furthermore, we propose ways in which AR could be used collaboratively and embedded in existing participation processes.

LIMITS ’21: Workshop on Computing within Limits., Pages: 13
[BibTeX] [Abstract]Can cattle farmers live peacefully alongside lions, and what role can technology play in this sensitive setting? Since 2017, we have been investigating this question in the Okavango Delta, Botswana, using a Grounded Design (GD) approach. Based on community involvement we have been building and evaluating a system together with local and foreign experts which warns the locals when a lion comes near their village or their cattle and which has significantly reduced livestock predation by giving time for action. However, as our research shows, technology alone is not the solution for locals’ problems: education, knowledge transfer, economic self-determination, as well as the revival of herding traditions and lost connection to nature need to evolve further to foster a true coexistence between humans and predators in Botswana – and perhaps all over the world. To address these problems and solutions by design and ensure sustainability of its outcome, it is important to take into account the oral culture and collective history of the inhabitants with predators, especially lions. Consideration must also be given to their social environment and individual experiences and goals, as well as their digital infrastructure, accessibility, and digital ecologies. We therefore argue that the successful development of a design solution requires a holistic understanding of design that is built on inclusion, participation, collaboration, understanding, respect, sacredness and the always-recurrent cyclic renovation of life.

[BibTeX] [Abstract] [Download PDF]Critical consumerism is complex as ethical values are difficult to negotiate, appropriate products are hard to find, and product information is overwhelming. Although recommender systems offer solutions to reduce such complexity, current designs are not appropriate for niche practices and use non-personalized intransparent ethics. To support critical consumption, we conducted a design case study on a personalized food recommender system. Therefore, we first conducted an empirical pre-study with 24 consumers to understand value negotiations and current practices, co-designed the recommender system, and finally evaluated it in a real-world trial with ten consumers. Our findings show how recommender systems can support the negotiation of ethical values within the context of consumption practices, reduce the complexity of finding products and stores, and strengthen consumers. In addition to providing implications for the design to support critical consumption practices, we critically reflect on the scope of such recommender systems and its appropriation.

In this paper, we report on efforts to provide alternative, more sustainable and resilient models of production. Community Supported Agricultures (CSAs) address this problem but require new means of exchange which, we suggest, offer a design opportunity for sustainable HCI research. This paper presents a two months participatory observation in a food movement, a German CSA which developed a distribution system involving their own currency. Based on our ethnographic observations, we focus our discussion on (1) the solidaristic principles upon which the movement is based and (2) techniques of mediating between consumers’ wishes and the constraints of local agricultural production. By relating to the continued development of CSAs, we identify three interrelated innovation gaps and discuss new software architectures aimed at resolving the problems which arise as the movement grows.

[BibTeX] [Abstract] [Download PDF]It is sometimes argued that there is hardly a place in the world in the 21st century left untouched by global capitalism [111, 112]. Even so, some places remain at the periphery, participating in this system without being fully absorbed by it. In this article, we take a detailed look at the economic life of such a “pericapitalist” [161] community in the Brazilian Amazon region. We detail how the community increasingly participates in global systems and supply chains, yet also organizes economic life around local and traditional values. We pay special attention to the role of digital technologies in the community, including mobile phones and internet. The contribution of the article is as follows: firstly, it provides a detailed analysis of the material practices of a community at the edge. Secondly, it draws attention to the heterogeneous nature of responses to global capitalism, formed from the relationship between specific material practices, new technology, and elements of cultural identity. Thirdly, it argues for an increased sensibility towards these different relations to capitalism when considering design implications. We argue that close attention to material practice goes some way towards resolving those tensions and, further, provides for an appeal to a more pluralistic views of culture and development [61].

(Journal of Computer Supported Cooperative Work, vol. 18, no. 2–3, 2009, pp. 199–227, 2009) showed that using just an audio channel for remote troubleshooting can lead to a range of problems and already envisioned a future in which augmented reality (AR) could solve many of these issues. In the meantime, AR technologies have found their way into our everyday lives and using such technologies to support remote collaboration has been widely studied within the fields of Human-Computer Interaction and Computer-Supported Cooperative Work. In this paper, we contribute to this body of research by reporting on an extensive empirical study within a Fab Lab of troubleshooting and expertise sharing and the potential relevance of articulation work to their realization. Based on the findings of this study, we derived design challenges that led to an AR-based concept, implemented as a HoloLens application, called shARe-it. This application is designed to support remote troubleshooting and expertise sharing through different communication channels and AR-based interaction modalities. Early testing of the application revealed that novel interaction modalities such as AR-based markers and drawings play only a minor role in remote collaboration due to various limiting factors. Instead, the transmission of a shared view and especially arriving at a shared understanding of the situation as a prerequisite for articulation work continue to be the decisive factors in remote troubleshooting.

Khosravani, M. R., Schüürmann, J., Berto, F. & Reinicke, T. (2021)On the Post-Processing of 3D-Printed ABS Parts
IN Polymers, Vol. 13, Pages: 1559 doi:10.3390/polym13101559
[BibTeX] [Abstract] [Download PDF]Application of Additive Manufacturing (AM) has significantly increased in the past few years. AM also known as three-dimensional (3D) printing has been currently used in fabrication of prototypes and end-use products. Considering the new applications of additively manufactured components, it is necessary to study structural details of these parts. In the current study, influence of a post-processing on the mechanical properties of 3D-printed parts has been investigated. To this aim, Acrylonitrile Butadiene Styrene (ABS) material was used to produce test coupons based on the Fused Deposition Modeling (FDM) process. More in deep, a device was designed and fabricated to fix imperfection and provide smooth surfaces on the 3D-printed ABS specimens. Later, original and treated specimens were subjected to a series of tensile loads, three-point bending tests, and water absorption tests. The experimental tests indicated fracture load in untreated dog-bone shaped specimen was 2026.1 N which was decreased to 1951.7 N after surface treatment. Moreover, the performed surface treatment was lead and decrease in tensile strength from 29.37 MPa to 26.25 MPa. Comparison of the results confirmed effects of the surface modification on the fracture toughness of the examined semi-circular bending components. Moreover, a 3D laser microscope was used for visual investigation of the specimens. The documented results are beneficial for next designs and optimization of finishing processes.

doi:10.18420/ecscw2021_wsmc06
[BibTeX] [Abstract] [Download PDF]Within the fields of Human-Computer Interaction (HCI) and Computer- Supported Cooperative Work (CSCW), there is a wide acknowledgement that, in order to design useful and usable interactive systems, it is key to accurately understand users, their contexts and the practices they engage with. For that, HCI and CSCW professionals have for long been drawing on socio-scientific methods as a means towards it. While much has been said in terms of methods that can be used to capture the user contexts and associated practices, considerably less is found on how the collected data can be systematically analysed, in order to generate trustworthy representations of what has been heard and observed from participants. One possible reason for that is the lack of training of researchers in the area to use appropriate data analysis techniques. This masterclass sets out to address this gap. It aims at providing HCI and CSCW researchers and practitioners with deep knowledge about one of the most popular data analysis technique of the moment: Thematic Analysis (TA). Through a practical exercise, the masterclass will introduce and explore the procedures involved in carrying out TA, so to equip professionals from the field with the necessary tools to have a good understanding of the relevant user contexts and practices for the design of innovative, useful and usable interactive systems.

[BibTeX] [Abstract] [Download PDF]In diesem Working Report werden Ergebnisse einer Umfrage in Nordrhein-Westfalen präsentiert, die Einstellungen der Bevölkerung zur Windenergie widerspiegeln. Die Abfragen zeigen, dass Klimaschutz-Maßnahmen, die Energiewende und der Ausbau der Windkraft große Zustimmung bei der Bevölkerung finden. Bei der Windenergie wird ein Nutzen für die lokale Gemeinschaft präferiert, bestenfalls durch direkten Bezug günstigen Stroms. Im Falle der Planung neuer Windparks werden detaillierte Informationen gewünscht, wobei wissenschaftlichen Informationsquellen am stärksten vertraut wird. Klassische Informationsveranstaltungen werden überwiegend bevorzugt, sehr viel weniger Online-Formate. Die Hälfte der Befragten würde eine Visualisierungs-App für das Smartphone benutzen. Finanzielle Beteiligung wird zwar stark von monetären Anreizen oder einem vergünstigen Stromtarif abhängig gemacht, wird aber auch durch Klimaschutz-Einstellungen beeinflusst. Planungskonflikte sollten durch Bürgerentscheide, Experten oder Bürgerversammlungen gelöst werden. Damit unterstreichen die Ergebnisse die Bedeutung von qualitätsvoller Informierung, Beteiligung und Neutralität für die Akzeptanz von Windenergie.

Older adults in particular experience various forms of ageism in this regard, for example by being stereotyped as digitally illiterate. Hence, we need to learn more about the aging discourse in the context of participatory approaches, as it is currently lacking. This article presents the results from two participatory research projects that were significantly affected by the 1st COVID-19 lockdown. We specifically focus on the ways the relationships and modes of cooperation with our older research partners, i.e. the positionalities, have been impacted. We draw on the projects’ results, reflecting on the possible implications for the involvement of older adults in design and HCI research and specifically, technologies that are supportive and empowering for the individuals against the background of the pandemic situation.

[BibTeX] [Abstract] [Download PDF]Understanding user contexts and practices for the design and development of useful and usable technologies has for long been acknowledged as relevant within the fields of Human-Computer Interaction (HCI) and Computer-Supported Cooperative Work (CSCW). Taking account of the growing interest in human practices for the design and quality assessment of digital technologies, Grounded Design (GD) has been introduced as a paradigm for design research and practice. As a research paradigm, GD focuses on investigating changes in human practices stemming from the use and appropriation of digital technologies. The results of such investigations are used as input for the design and development of new and innovative digital solutions. In this context, Design Case Study (DCS) serves as a framework to orient and document research and practice predicated on GD. The framework, which is organised in three interdependent phases – pre-study, design and appropriation –, provides useful guidance and infrastructure for successful GD initiatives. This masterclass sets out to demonstrate how DCS can be used to accomplish relevant and impacting GD projects. It will introduce the conceptual and theoretical grounds behind the framework, as well as discuss the different methods and methodologies which can be used for it.

These adaptations can be crucial to overcoming the current disruptions challenging the continued existence keeping in view the intrinsic diversification of various business and industrial sectors. How organizational infrastructures can be designed to instill resilient properties like adaptive capacity, self-adjustment and continuity? We intend to focus on bringing this discussion under the umbrella of CSCW to explore the potentials of collaboration and cooperative work in organizational infrastructure. Through this workshop, we offer research prospects by applying organizational resilience theories to study organizational infrastructure and infrastructuring activities, which can be used for their prospective transformations into resilient infrastructures.}, language = {en}, urldate = {2021-04-15}, author = {Syed, Hussain Abid and Schorch, Marén and Ankenbauer, Sam Addison and Hassan, Sohaib and Meisner, Konrad and Stein, Martin and Skudelny, Sascha and Karasti, Helena and Pipek, Volkmar}, year = {2021}, } -

[BibTeX] [Abstract]Industrial set-up has long been a focus of scientific research, largely because it entails substantial cost overhead for manufacturing companies. Whilst various efforts have been made to optimise this process, mainly in terms of time and other resources needed to accomplish it, to date little can be found in the HCI literature about how digital technologies can support workers who engage in it. This article sets out to addresses this gap in the literature by introducing a design case study carried out for the conception of a CPPS (Cyber-physical Production System) to support machine operators with industrial set-up. Our contribution is therefore threefold: first, we describe and discuss the results of an in-depth ethnographic study, carried out under the premises of the grounded design research paradigm, to uncover practices of machine operators to inform design. Second, we introduce a series of design implications drawn from those results. Finally, we demonstrate how those design implications have informed the participatory design activities pursued for the conception of the CPPS in question. In so doing, we advance the state of the art on the design of digital technologies to support people working with industrial set-up and open new research directions on the subject.

Jakobi, T., Alizadeh, F., Marburger, M. & Stevens, G. (2021)A Consumer Perspective on Privacy Risk Awareness of Connected Car Data Use
doi:10.1145/3473856.3473891
[BibTeX] [Abstract] [Download PDF]New cars are increasingly „connected“ by default. Since not having a car is not an option for many people, understanding the privacy implications of driving connected cars and using their data-based services is an even more pressing issue than for expendable consumer products. While risk-based approaches to privacy are well established in law, they have only begun to gain traction in HCI. These approaches are understood not only to increase acceptance but also to help consumers make choices that meet their needs. To the best of our knowledge, perceived risks in the context of connected cars have not been studied before. To address this gap, our study reports on the analysis of a survey with 18 open-ended questions distributed to 1,000 households in a medium-sized German city. Our findings provide qualitative insights into existing attitudes and use cases of connected car features and, most importantly, a list of perceived risks themselves. Taking the perspective of consumers, we argue that these can help inform consumers about data use in connected cars in a user-friendly way. Finally, we show how these risks fit into and extend existing risk taxonomies from other contexts with a stronger social perspective on risks of data use.

doi:10.18420/IHC2021_003
[BibTeX] [Abstract] [Download PDF]Demographic transformation and medical-technical progress are generating new demands for standards and quality in professional caregiving. The job profile and especially the nature of care apprenticeships is changing significantly and use of digital media is becoming an increasingly ubiquitous and important aspect of the work. In this paper, we present a design case study that focuses on the development and evaluation of a multimedia learning application for and with care students. Adopting a user-centered design approach, we collected design requirements for the application in workshops and interviews with 23 care-students. The results show that it is important to create a structured approach to providing information and that social aspects such as chat allow for higher motivation and collaboration in learning. The findings also suggest that, by using game mechanisms such as a quizzes and difficulty levels, care-students can be further motivated to become more engaged with learning content.

[BibTeX] [Abstract]Scrum, the most popular form of agile, is often cited for creating a positive working environment for women. Its values, principles, roles, and practices are said to hold great potential to promote fairness and gender equality. But does it? Social scientific literature has identified two key dimensions to analyze processes. The first dimension examines whether practices, behaviors, values, and attitudes are explicit or implicit. The second dimension separates the team experience from the individual experience. Using these dimensions to inform thinking about gender issues in processes and our data from women working on Scrum teams, we developed an analysis framework to surface gender issues in Scrum. We share what works and doesn’t work for women in Scrum and where improvements can be made.

Proceedings of 19th European Conference on Computer-Supported Cooperative Work., Publisher: European Society for Socially Embedded Technologies (EUSSET) doi:10.18420/ecscw2021_ep27
[BibTeX] [Abstract] [Download PDF]Carrying out successful design workshops can be a challenging task. This can turn even more difficult, if one attempts to engage in more inclusive design workshops, where a broad range of user profiles are covered. If some of these profiles refer to people with impairments, things can get even more complicated. Furthermore, there are also associated challenges when trying to carry out something that is usually implemented as a face-to-face activity in an online format. This exploratory paper introduces a discussion on a few lessons learned from organising design workshops including both people with and without visual impairments. It also outlines our response to the situation created by the COVID-19 pandemic, which prevented us to engage in face-to-face design workshops. Based on feedback received from participants of a first in-person design workshop organised within one of our projects and on informal interviews carried out mainly over the phone to discuss ways to enhance the collaboration between people with and without visual impairments during such activities, we go on to introduce some relevant aspects that should be taken into consideration when planning inclusive design workshops. This is a preliminary contribution, meant to raise discussions on technology-mediated inclusive participatory design initiatives to further inform the development of a solid methodological contribution to CSCW.

Based on feedback received from participants of a first in-person design workshop organised within one of our projects and on informal interviews carried out mainly over the phone to discuss ways to enhance the collaboration between people with and without visual impairments during such activities, we go on to introduce some relevant aspects that should be taken into consideration when planning inclusive design workshops. This is a preliminary contribution, meant to raise discussions on technology-mediated inclusive participatory design initiatives to further inform the development of a solid methodological contribution to CSCW.}, language = {en}, urldate = {2021-05-25}, booktitle = {Proceedings of 19th {European} {Conference} on {Computer}-{Supported} {Cooperative} {Work}}, publisher = {European Society for Socially Embedded Technologies (EUSSET)}, author = {Bittenbinder, Sven and Pinatti de Carvalho, Aparecido Fabiano and Krapp, Eva and Müller, Claudia and Wulf, Volker}, year = {2021}, note = {Accepted: 2021-05-18T10:05:02Z Publisher: European Society for Socially Embedded Technologies (EUSSET)}, keywords = {italg}, } -
Abele, N. D., Hoffmann, S., De Carvalho, A. F. P., Schweitzer, M., Wulf, V. & Kluth, K. (2021)Knowledge and Expertise Sharing – Designing an AR-Mediated Cyber-Physical Production System for Industrial Set-Up Processes
Proceedings of the 21st Congress of the International Ergonomics Association (IEA 2021). Cham, Publisher: Springer International Publishing, Pages: 347–354 doi:10.1007/978-3-030-74608-7_44
[BibTeX] [Abstract]Cyber-Physical Production Systems (CPPS) are receiving a lot of attention in the context of the fourth industrial revolution, especially in terms of complex architectures for data exchange among intelligent machines. However, the present elaboration is rather based on the question of what support such systems can provide for the exchange and appropriation of knowledge-intensive human practices in industrial surroundings. This paper presents the method and conceptual foundations of an Augmented Reality (AR) and sensor technology based CPPS for manual set-up processes on modern production machines. In the present context, both the recording of physical movements and the representation of local knowledge are potentially relevant. The basis is formed by design implications identified in the course of an extensive ethnographic study through the implementation of which a new methodological approach to the capture and transfer of (technical) knowledge embedded in embodied actions could be realized.

Nevertheless, there are only a few empirical studies that outline the use of current technologies within eating contexts. We therefore conducted an empirical study on the practice of eating out and the use of mobile technologies before, during, and after eating. Our investigation consists of a qualitative interview study (n=29) complemented by a large observational study (n=458) within several restaurant settings. Our results indicate a strong reluctance to use technology while eating and highlights several design spaces focusing on before and after the actual eating. Within our paper, we uncover a strong relationship between smartphone use and the social settings in which the interaction takes place. We contribute to the emerging research field of Human-Food Interaction by outlining design spaces for supporting practices around food consumption when eating out.

[BibTeX] [Abstract] [Download PDF]It is anticipated that autonomous vehicles will have a huge impact on the creation of sustainable smart cities and communities. One of the key concerns regarding autonomous vehicles is how automation may threaten jobs in the transport industry, including the traditional role of taxi drivers. To begin to explore how important an actual taxi driver is to customers and the extent to which they might be happy to have autonomous taxis replace traditional taxis, we conducted qualitative interviews with 34 Millennial-aged participants. These were problem-centered narrative interviews, largely conducted face-to-face, and analyzed using thematic analysis. Millennials were focused upon because, given current figures and likely future projections of use, they form the key market for prospective future autonomous taxis. The results show that the kind of taxi rides Millennials make are particularly suitable for automated taxis because interaction with a human driver is not a high priority for this group, while the prospect of autonomous taxis being cheaper is. Meanwhile the fate of taxi drivers does not play a significant part in how Millennials reason about this. An incidental finding, here, is that, by offering a convenient and affordable alternative, the advent of automated taxis may also pose a threat to public transportation.

[BibTeX] [Abstract] [Download PDF]This study examines the appropriation and usage of voice assistants like Google Assistant or Amazon Alexa in private households. Our research is based on 10 in-depth interviews with users of voice assistants and a follow-up evaluation of their interaction histories. Our results illustrate situations in which the voice assistants were used at home, what strategies the users adopted to interact with them, how the interactions were performed, and what difficulties users experienced. A focus of our study is on misunderstandings, situations where interactions failed partially or completely. Our study shows that the full potential of voice assistants is often not utilized, as complex interactions are often subject to failures and users revert to simple use cases. Our participants used their voice assistant mostly for simple commands, often not even trying new functions. An analysis of their appropriation strategies resulted in implications for the design of supportive tools as well as the further development and optimization of voice interfaces.

Lawo, D., Böhm, L. & Stevens, G. (2020)Veganaizer: AI-assisted Ingredient Substitution
doi:10.13140/RG.2.2.18736.17922
[BibTeX] [Abstract]Plant-based diets, once considered to be something of a fad, have now taken on an entirely new significance as the ecological consequences of diet choice have become more apparent; it is now acknowledged that dietary choices have significant consequences for sustainability. However, plant-based cooking and the veganization of recipes are things newcomers to these cuisines struggle with. Attempting to support sustainable food choices and the learning of plant-based cooking, we propose a novel end-to-end approach for AI-assisted recipe veganization called Veganaizer. To support people in finding matching plant-based substitutes for the ingredients of their favorite recipes, Veganaizer generates ranked lists of substitutes learned from their ingredient embeddings. The system is currently developed as part of an Android App. Veganaizer exploits the state-of-the-art word embedding algorithm fastText, trained on vegan and omnivorous recipes scraped from two popular German websites. In this paper, we describe the architecture of the system, conduct performance comparisons with a Word2vec-based approach to transform regional cuisine styles as well as a Singular Value Decomposition based approach, and discuss challenges of the Veganaizer model with two complementary qualitative case studies. Although the evaluation with a handcrafted validation data set shows a top-1 accuracy of 72.9\%, surpassing the best baseline model by 31\%, an expert-based evaluation identified limitations, but also capabilities, of the current approach. Based on these findings we formulate demand for future research.

The system is currently developed as part of an Android App. Veganaizer exploits the state-of-the-art word embedding algorithm fastText, trained on vegan and omnivorous recipes scraped from two popular German websites. In this paper, we describe the architecture of the system, conduct performance comparisons with a Word2vec-based approach to transform regional cuisine styles as well as a Singular Value Decomposition based approach, and discuss challenges of the Veganaizer model with two complementary qualitative case studies. Although the evaluation with a handcrafted validation data set shows a top-1 accuracy of 72.9\%, surpassing the best baseline model by 31\%, an expert-based evaluation identified limitations, but also capabilities, of the current approach. Based on these findings we formulate demand for future research.}, author = {Lawo, Dennis and Böhm, Lukas and Stevens, Gunnar}, month = sep, year = {2020}, doi = {10.13140/RG.2.2.18736.17922}, } -
Ludwig, T., Hoffmann, S., Jasche, F. & Ruhrmann, M. (2020)VacuumCleanAR: augmented reality-based self-explanatory physical artifacts
Proceedings of the Conference on Mensch und Computer. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 291–302 doi:10.1145/3404983.3405526
[BibTeX] [Abstract] [Download PDF]Consumer purchase decisions are not only determined by the quality or price of a product. Customers also want an innovative product that they can identify with in something more than just a functional way. Much of this appeal is often bound up with the innovative character of a product. However, the global market and the huge variety of products available make it challenging for companies to help customers understand the particular innovations in their products, especially in terms of technical „hidden“ innovations. Augmented reality (AR) offers interactive experiences in real-world environments through digitalized information. In this paper, we present a design case study about an AR-based approach to reveal the hidden innovations to potential users in an engaging and „emotional“ way by using the example of a vacuum cleaner. Based on an empirical study, we designed and implemented the fully functional HoloLens application VacuumCleanAR, which allows users to discover the hidden innovations of a vacuum cleaner in a less functional and more consumer-centric way. This reveals the scope for augmenting other physical artifacts in a similar fashion.

[BibTeX] [Abstract] [Download PDF]In 2019 it was revealed that several providers of voice assistants had systematically evaluated voice recordings of their users. Since the data protection notices stated that data would also be used to improve the service, this use was legal. For the users, however, this evaluation represented a clear break with their expectations of privacy. The purpose limitation principle of the GDPR with its component of purpose specification requires flexibility for the processor as well as transparency for the consumer. Against the background of this conflict of interest, the question arises for HCI as to how processing purposes of voice assistants should be designed to meet both requirements. To collect a user perspective, this study first analyzes the data protection information of the dominant voice assistants. Based on this, we present results of focus groups that deal with the perceived processing of data of voice assistants from the user perspective. The study shows that existing purpose statements offer hardly any transparency for consumers regarding the consequences of data processing and do not have any restrictive effect with regard to legal data use. Our results on risks perceived by users allow us to draw conclusions about the user-friendly design of processing purposes in terms of a design resource.

Für die NutzerInnen stellte diese Auswertung jedoch einen deutlichen Bruch mit ihren Privatheitsvorstellungen dar.

Für die Erhebung einer Nutzerperspektive analysiert diese Studie zunächst Zweckangaben in den Datenschutzhinweisen der dominierenden Sprachassistenten. Darauf aufbauend präsentieren wir Ergebnisse von Fokusgruppen, die sich mit der wahrgenommenen Verarbeitung von Daten von Sprachassistenten aus Nutzersicht befassen. Es zeigt sich, dass bestehende Zweckformulierungen für VerbraucherInnen kaum Transparenz über Folgen der Datenverarbeitung bieten und keine einschränkende Wirkung im Hinblick auf legale Datennutzung erzielen.

[BibTeX] [Abstract]Today, more personal data than ever before Is being collected and stored by companies of all types for a wide variety of purposes. The General Data Protection Regulation (GDPR) aims to strengthen the rights of consumers by providing them with tools for controlling data collection and processing. While companies are now subject to legal obligations, precedent cases are still missing. At the same time. It remains unclear how the right to access data can be concretely implemented in practical and technical terms. Our study intends to address this problem by investigating the case ofloyalty card providers-an established branch that collects the purchase data of users in exchange for discounts. For our study, we asked 13 households to request their personal data from their respective loyalty program providers. Based on interviews, we investigate the expectations of these users of the GDPR and the right to access data. Furthermore, we analyze the currently implemented process of claiming and receiving data as well as the sensemaking of said data by the users. Based on our analysis, we make the following contributions: We shed light on what users know about and expect from the GDPR, particularly concerning the right to access, we report user expectations regarding the process to claim access to data and the data archives provided, and finally, we also show why also companies could benefit from actively designing the data takeout to demonstrate their data collection practices.

[BibTeX] [Abstract] [Download PDF]Technical advantages of additive manufacturing (AM) have drawn great attention over the past few years. This cost-effective manufacturing process proved its potential applications in a wide range of fields. Although AM techniques (known as 3D printing) are able to fabricate geometrically complex components, it is necessary to evaluate internal and external dimensions of the printed parts. In this context, x-ray computed tomography (CT) as a nondestructive evaluation technique has been utilized. Indeed, CT can be used for geometric analysis, defects detection, quantitative comparison, structural quantification and porosity analysis. In the current study, we present a brief review of 3D printing processes and evolution of CT technology. Moreover, applications of CT in assessment of 3D-printed components are explained in detail. Although CT has been used in academic and industrial researches, abilities of this inspection method are not yet fully documented for precision engineering applications. In this work, usage of this technique in study of printed components are categorized in four subdomains and discussed. The documented data proved that CT is an appropriate non-contact technique for technical evaluation of various printed parts. As usage of CT in assessment of printed parts is still evolving, the limitations, challenges and future perspective are outlined.

[BibTeX] [Abstract] [Download PDF]Due to the increase in natural disasters in the past years, Disaster Response Organizations (DROs) are faced with the challenge of coping with more and larger operations. Currently appointed Information and Communications Technology (ICT) used for coordination and communication is sometimes outdated and does not scale, while novel technologies have the potential to greatly improve disaster response efficiency. To allow adoption of these novel technologies, ICT system designers have to take into account the particular needs of DROs and characteristics of International Disaster Response (IDR). This work attempts to bring the humanitarian and ICT communities closer together. In this work, we analyze IDR-related documents and conduct expert interviews. Using open coding, we extract empirical insights and translate the peculiarities of DRO coordination and operation into tangible ICT design requirements. This information is based on interviews with active IDR staff as well as DRO guidelines and reports. Ultimately, the goal of this paper is to serve as a reference for future ICT research endeavors to support and increase the efficiency of IDR operations.

[BibTeX] [Abstract] [Download PDF]Autonomous driving enables new mobility concepts such as shared-autonomous services. Although significant re-search has been done on passenger-car interaction, work on passenger interaction with robo-taxis is still rare. In this paper, we tackle the question of how passengers experience robo-taxis as a service in real-life settings to inform the interaction design. We conducted a Wizard of Oz study with an electric vehicle where the driver was hidden from the passenger to simulate the service experience of a robo-taxi. 10 participants had the opportunity to use the simulated shared-autonomous service in real-life situations for one week. By the week’s end, 33 rides were completed and recorded on video. Also, we flanked the study conducting interviews before and after with all participants. The findings provided insights into four design themes that could inform the service design of robo-taxis along the different stages including hailing, pick-up, travel, and drop-off.

Vaziri, D., Golchinfar, D., Stevens, G. & Schreiber, D. (2020)Exploring Future Work – Co-Designing a Human-robot Collaboration Environment for Service Domains
Proceedings of the 2020 ACM Designing Interactive Systems Conference. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 153–164 doi:10.1145/3357236.3395483
[BibTeX] [Abstract] [Download PDF]There has been increasing interest in the application of humanoid robots in service domains like retail or care homes in recent years. Here, most use cases focus on serving customer needs autonomously. Frequently, human intervention becomes necessary to support the robot in exceptional situations. However, direct intervention of service operators is often not possible and requires specialized personnel. In a co-design process with 13 service operators from a pharmacy, we designed a remote working environment for human-robot collaboration that enables first-time experiences and collaboration with robots. Five participants took part in an assessment study and reported on their experiences about the utility, usability and user experience. Results show that participants were able to control and train the robot through the remote control environment.

IN Human–Computer Interaction, Pages: 1–34 doi:10.1080/07370024.2020.1746910
[BibTeX] [Abstract] [Download PDF]This paper presents the outcomes of an exploratory study focused on the evaluation of an interactive music exergame for People with Dementia (PwD) and their caregivers. PwD tend to isolate themselves from the outside world, therefore carers need to develop strategies to maintain communication with them. Studies indicate that music–based activities provide an effective way to achieve social interaction with PwD. At the same time, physical activity plays a major role in dementia-related interventions because it can slow down progression and provide meaningful stimulation. Our developed interactive music game bounds these two concerns together; we evaluated the system afterwards regarding its individual and social impact and its integration into the daily routines of both PwD and their caregivers, focusing on its capacity to provide both enjoyment and relief from some of the effects of dementia. Qualitative data collected over 4 months confirmed the valuable impact of music-based interventions of PwD. Of particular note was how PwD used the game to improve or maintain their physical condition while recovering past memories and an interest in social interaction.

For a long time now, the ’smart fridge‘ is promised to improve everyday life in private households, supporting healthy eating habits and sustainable food practices. However, current technology is still not widespread and limited in its functions. Similarly, researched prototypes are rather persuasive and not aligned with consumers‘ storage practices. We took a practice theoretical lens to investigate current storage practices and actual refrigerators. As follows we present our work in progress and first insights from our contextual inquiry.

Castelli, N. (2020)Designing Human-Centered Systems for the Internet of Things – Design-Case Study inspired Concept for End-User Data Work for tailorable information visualizations and analysis of IoT and IIoT Data
Dissertation, Siegen
[BibTeX] [Abstract] [Download PDF]The Internet of Things (IoT) and the Industrial Internet of Things (IIoT) are fast-growing emerging topics of technical, social, and economic significance that not only affect work practices but also daily routines and habits. The IoT and IIoT comprise a network of smart physical things and devices (such as production machines and home appliances). The number of “things” connected via the internet or the intranet is constantly increasing. It is estimated that approximately 20 billion IoT devices will be online by 2020 [179]. Internet of Things and IIoT devices communicate with one another through software technology with the aim of making them more autonomous and cooperative [334]. In addition to technological advances in hardware for the efficient acquisition and communication of context and status data, software solutions in particular offer great potential for influencing many areas of everyday life and work; to this end, humans should be taken into account when designing new digital systems. The central element here is the use of digital data, which are now available in greater quantities and at a better quality than ever before. Currently, the amount of data produced daily is 2.5 quintillion bytes–this will continue to increase in coming years [366]. These data contain much valuable information, which can only be obtained through appropriate data analyses and visualization and correct embedding in their context. The term “data work” has evolved as a superordinate area that combines all aspects of work with data to derive meaningful information, such as data consolidation, data processing, data refinement, data analysis, and data visualization [119]. This thesis focuses on end-user data work in the context of IoT and IIoT systems that supports users using their digital data by providing tailorable information visualizations and data analysis. From a Human Computer Interaction (HCI) perspective, this thesis examines how IoT and IIoT systems have to be designed to enable end-users to make digital data meaningful and usable. In this regard, and combining the areas of IoT system design, end-user development (EUD) and information visualization, the main goals of this thesis are: • To gain a deeper understanding of the use and appropriation of IoT and IIoT technology in different contexts, • To gain insights about the use of digital data for daily routines, habits and work practices; and • To evaluate possibilities for the development of a system design for end-user data work. This work is based on empirical field studies that investigate different settings (domestic and industrial) in the context of IoT and IIoT. Seen through the lens of appropriation [37, 99, 102, 291, 337], relevant practices for deploying and using IoT and IIoT technology, especially the practices of working with digital data to support routines, habits, and processes, are identified and discussed for different application areas. This has resulted in the development of system requirements to support the process of making abstract digital data accountable and meaningful for users in their everyday life and work practices. Grounded in these results, a concept of an end-user data work tool that allows the consolidation of digital data across system boundaries, lets users adjust the system to their context, supports flexible data visualizations, and empowers collaborative data work is presented.

[BibTeX] [Abstract]Made to Work analyses the conditions of mobile knowledge work (MKW) in contemporary worklives, contrasting and drawing parallels among three highly significant sectors of the Knowledge Economy: academia, information communication technology (ICT) management, and digital creative work. It introduces the concept of ‘corollary work’ to characterise the elusive work underpinning the configuration of workers, informational, technological, relational and infrastructural resources in (re)producing liveable worklives. It ultimately illuminates the myriad strands of corollary work that enable MKW to take place and contributes to emergent debates on how exploitation, at least in the domain of MKW, can be named, resisted and creatively subverted. In so doing, it opens up a conversation about the complex ways in which contemporary worklives are ‘made to work’, and about potential interventions to bring about more just worklife conditions in the future.

[BibTeX] [Abstract] [Download PDF]There has been increasing interest in designing for dementia in recent years. Empirical investigation is now needed of the long-term role of caregivers in appropriating ICTs into the complex daily life of people with dementia (PwD). We present here the outcomes of a 4-month evaluation of the individual, social and institutional impact of a videogame-based training system. The everyday behavior and interactions of 52 PwD and 25 caregivers was studied qualitatively, focusing on the role played by caregivers in integrating the system into daily routines. Our results indicate that the successful appropriation of ICT for PwD depends partly on the physical, cognitive and social benefits for PwD, but especially on the added value perceived by their social care-network. We discuss the need for design in dementia to develop more socially embedded innovations that can address the social actors involved and thus contribute to practical solutions for professional and private care.

Some studies, however, indicate that the introduction of AVs may cause rebound effects that could further harm the environment such unintended modal shifts. Currently focusing on user experience design, there is an urgent need for HCI researchers to consider such negative consequences in order to responsibly design sustainable AVs.

[BibTeX] [Abstract] [Download PDF]The aim of this paper is to suggest a framework for categorizing social robots with respect to four dimensions relevant to an ethical, legal and social evaluation. We argue that by categorizing them thusly, we can circumvent problematic evaluations of social robots that are often based on overly broad and abstract considerations. Instead of questioning, for example, whether social robots are ethically good or bad in general, we instead propose that different configurations of (and combinations thereof) the suggested dimensions entail different paradigmatic challenges with respect to ethical, legal and social issues (ELSI). We therefore encourage practitioners to consider these paradigmatic challenges when designing social robots to find creative design solutions.

[BibTeX] [Abstract] [Download PDF]Ageing societies and the associated pressure on the care systems are major drivers for new developments in socially assistive robotics. To understand better the real-world potential of robot-based assistance, we undertook a 10-week case study in a care home involving groups of residents, caregivers and managers as stakeholders. We identified both, enablers and barriers to the potential implementation of robot systems. The study employed the robot platform Pepper, which was deployed with a view to understanding better multi-domain interventions with a robot supporting physical activation, cognitive training and social facilitation. We employed the robot in a group setting in a care facility over the course of 10 weeks and 20 sessions, observing how stakeholders, including residents and caregivers, appropriated, adapted to, and perceived the robot. We also conducted interviews with 11 residents and caregivers. Our results indicate that the residents were positively engaged in the training sessions that were moderated by the robot.

To understand better the real-world potential of robot-based assistance, we undertook a 10-week case study in a care home involving groups of residents, caregivers and managers as stakeholders. We identified both, enablers and barriers to the potential implementation of robot systems. The study employed the robot platform Pepper, which was deployed with a view to understanding better multi-domain interventions with a robot supporting physical activation, cognitive training and social facilitation. We employed the robot in a group setting in a care facility over the course of 10 weeks and 20 sessions, observing how stakeholders, including residents and caregivers, appropriated, adapted to, and perceived the robot. We also conducted interviews with 11 residents and caregivers. Our results indicate that the residents were positively engaged in the training sessions that were moderated by the robot.

[BibTeX] [Abstract] [Download PDF]Trust is the lubricant of the sharing economy. This is true especially in peer-to-peer carsharing, in which one leaves a highly valuable good to a stranger in the hope of getting it back unscathed. Nowadays, ratings of other users are major mechanisms for establishing trust. To foster uptake of peer-to-peer carsharing, connected car technology opens new possibilities to support trust-building, e.g., by adding driving behavior statistics to users‘ profiles. However, collecting such data intrudes into rentees‘ privacy. To explore the tension between the need for trust and privacy demands, we conducted three focus group and eight individual interviews. Our results show that connected car technologies can increase trust for car owners and rentees not only before but also during and after rentals. The design of such systems must allow a differentiation between information in terms of type, the context, and the negotiability of information disclosure.

The aim of our research is to provide methodological support for understanding and sharing experiences of gendered practices in the IT industry and encouraging sustained reflection about these matters over time. We established a Living Lab with that end in view, aiming to enhance female participation in the IT workforce and committing ourselves to a participatory approach to the sharing of women’s experiences. Here, using the case of a German video game company which participated in our Lab, we detail our lessons learned. We show that this kind of long-term participation involves challenges over the lifetime of the project but can lead to substantial benefits for organizations. Our findings demonstrate that Living Labs are suitable for giving voice to marginalized groups, addressing their concerns and evoking change possibilities. Nevertheless, uncertainties about long-term sustainability remain.

However, studies addressing the industrial context are quite rare, and due to the diversity of machines, processes, tasks, personal motivations, teams and the specific organizational culture of companies, it is not sufficient to provide only consumption data. For an adequate consideration of these factors, detailed design guidelines and system concepts are currently missing. However, this study shows the potential that a common understanding of consumption data can emerge through suitable visualization to support everyday work and possibilities of data sharing. Therefore, we show exemplarily how a design can be derived from empirically collected requirements and how a system concept can look like that enrich current eco-feedback design research for the industrial context.

[BibTeX] [Abstract] [Download PDF]Participation of women in IT is still low and companies wonder which external communication measures are necessary to attract more female personnel. To gain a richer understanding of adequate gender sensitive ways of communicating towards girls and women, one needs to take into account contextual challenges. Following a Participatory Action Research approach, we conducted a qualitative field study in a video game company in a large city in Germany, identified areas of concern, and sketched out implications for gender-sensitive communication measures together with our participants. Findings show that addressing gender stereotypes, making role models visible, and using adequate channels is relevant. Some problems might be solved via short-term solutions, but the majority require a long-term perspective. Our lessons learned leave implications for companies in the IT sector who want to foster gender sensitive external communication measures and can contribute to the realization of more gender balanced working environments.

[BibTeX] [Abstract] [Download PDF]With the debate on climate change, topics of diet change and the reduction of animal products have become increasingly important in both public and academic discourses. However, sustainable ICT studies have so far focused on individual aspects, in particular investigating the criticized persuasive design approach. We argue for a broader perspective on the role(s) of ICT, one that helps in identifying opportunities to support consumer practice transformation, beyond motivational aspects. Based on retrospective interviews with 16 vegans, we argue to understand practice transformation as co-evolution of practices and ICT artefacts, as this perspective helps to understand how tensions arising from complex entanglements of practices, socio-material contexts, and communities can be resolved. Rather than a motivational process, we observe various roles of ICT artefacts co-evolving with practices: Ranging from initial irritation, to access to information about vegan practices, to the learning of vegan food literacy, to the negotiation of a vegan identity, and vegan norms at the intersection of the ‘odd’ and the ‘norm’.

[BibTeX] [Abstract] [Download PDF]This workshop sets out to provide a forum for discussing the potential of community-based participatory research (CBPR) to foster accessibility at the workplace. It aims at opening a space to engage people with and without disability in a discussion about how this approach can contribute to bring employees, employers, developers and researchers together for the elaboration of a sensitisation concept to make people aware of the relevance of developing and adopting highly accessible digital solutions for the workplace. In particular, it focuses on the potential of the approach to engage people with disability in research, development and, most importantly, in the job market. Ultimately, the workshop seeks to advance the discussion of how this type of research can contribute towards the inclusion of people with disability in society and to highlight the benefits of that. The workshop is based on the European CSCW tradition of using in-depth qualitative methodologies for workplace studies and practice-based computing. It addresses issues of cooperation and collaboration between research actors, in the pursuit of a deep understanding of work contexts and the design of socio-technical systems that respond to their emerging needs.

[BibTeX] [Abstract] [Download PDF]Usability und User Experience (UX) haben als Design-Aspekte in der Produktentwicklung zunehmend an Bedeutung gewonnen. Daher ist es sinnvoll, die organisationale Kompetenz zur Ent-wicklung von Produkten mit einer positiven UX zu stärken. Ver-änderungen in Organisationen sind jedoch mit großem Aufwand verbunden. Deshalb müssen Organisationen entscheiden, welche Aktivitäten zur Veränderung der eigenen Kompetenz durchge-führt werden sollen und welche nicht. Die bisherige Forschung hat sich weitgehend auf die Anwendbarkeit bestimmter Metho-den im Projekt- und Produktkontext konzentriert. Um geeignete Aktivitäten zur Verbesserung der organisationalen UX-Kompetenz zu identifizieren, wurden 17 UX-Professionals be-fragt. Diese UX-Professionals haben mindestens zehn Jahre Er-fahrung durch die Arbeit in mehreren Unternehmen und durch die Übernahme einer Führungsrolle im Bereich UX gesammelt. Aus diesen Interviews wurden 13 mögliche Maßnahmen zur Steigerung der UX-Kompetenz von Organisationen abgeleitet. Dazu gehören beispielsweise die Erhöhung der Kompetenz ein-zelner Mitarbeiter, das Teilen von UX-Erfolgsgeschichten oder das Ermöglichen von User Research.

Die bisherige Forschung hat sich weitgehend auf die Anwendbarkeit bestimmter Metho-den im Projekt- und Produktkontext konzentriert. Um geeignete Aktivitäten zur Verbesserung der organisationalen UX-Kompetenz zu identifizieren, wurden 17 UX-Professionals be-fragt. Diese UX-Professionals haben mindestens zehn Jahre Er-fahrung durch die Arbeit in mehreren Unternehmen und durch die Übernahme einer Führungsrolle im Bereich UX gesammelt. Aus diesen Interviews wurden 13 mögliche Maßnahmen zur Steigerung der UX-Kompetenz von Organisationen abgeleitet. Dazu gehören beispielsweise die Erhöhung der Kompetenz ein-zelner Mitarbeiter, das Teilen von UX-Erfolgsgeschichten oder das Ermöglichen von User Research.}, language = {de}, urldate = {2021-04-16}, author = {Winter, Dominique and Stevens, Gunnar}, year = {2020}, note = {Accepted: 2020-09-09T15:02:15Z Publisher: Gesellschaft für Informatik e.V.}, } -

Thesis, Siegen
[BibTeX] [Abstract] [Download PDF]Since 1948, the Palestinian refugees are not allowed to go back to Palestine. The existence of the Israeli state prevented the Palestinian refugees to get back to their homes. Their houses and villages were depopulated and demolished. Traveling to Palestine could be intimidating for some people due to the perception that the western media have shown about the country. Palestinian refugees need to have access to see Palestine. Anybody who wants to visit the country, but has political situation concerns, must experience or see what to expect of a visit to Palestine. Action research was the concept of developing Glimpses from Palestine Virtual Reality application. The application development was based on the insights that were collected from interviews. The rebuilding of one of the demolished villages in Virtual Reality has given the application a historical and political aspect. The results show a strong connection between the second and third generations of Palestinians and Palestine. The transition of stories from grandparents to grandchildren in the diaspora and their effect on maintaining a strong relationship with the country. Also, the results showed the effect that Glimpses from Palestine has on people to preserve the value of their country and villages. This research explores the Virtual Reality as a new approach for documenting and displaying the historical events and facts of a country as Palestine, that the history and the demography of the country were changed due to political conflict.

[BibTeX] [Abstract]To assess perception with and performance of modern and future hearing devices with advanced adaptive signal processing capabilities, novel evaluation methods are required that go beyond already established methods. These novel methods will simulate to a certain extent the complexity and variability of acoustic conditions and acoustic communication styles in real life. This article discusses the current state and the perspectives of virtual reality technology use in the lab for designing complex audiovisual communication environments for hearing assessment and hearing device design and evaluation. In an effort to increase the ecological validity of lab experiments, that is, to increase the degree to which lab data reflect real-life hearing-related function, and to support the development of improved hearing-related procedures and interventions, this virtual reality lab marks a transition from conventional (audio-only) lab experiments to the field. The first part of the article introduces and discusses the notion of the communication loop as a theoretical basis for understanding the factors that are relevant for acoustic communication in real life. From this, requirements are derived that allow an assessment of the extent to which a virtual reality lab reflects these factors, and which may be used as a proxy for ecological validity. The most important factor of real-life communication identified is a closed communication loop among the actively behaving participants. The second part of the article gives an overview of the current developments towards a virtual reality lab at Oldenburg University that aims at interactive and reproducible testing of subjects with and without hearing devices in challenging communication conditions. The extent to which the virtual reality lab in its current state meets the requirements defined in the first part is discussed, along with its limitations and potential further developments. Finally, data are presented from a qualitative study that compared subject behavior and performance in two audiovisual environments presented in the virtual reality lab-a street and a cafeteria-with the corresponding field environments. The results show similarities and differences in subject behavior and performance between the lab and the field, indicating that the virtual reality lab in its current state marks a step towards more ecological validity in lab-based hearing and hearing device research, but requires further development towards higher levels of ecological validity.

Pakusch, C. (2020)Technology assessment of autonomous driving – are shared autonomous vehicles ecologically and socially sustainable?
doi:10.25819/ubsi/8475
[BibTeX] [Abstract] [Download PDF]Since its advent, the sustainability effects of the modern sharing economy have been the subject of controversial debate. While its potential was initially discussed in terms of post-ownership development with a view to decentralizing value creation and increasing social capital and environmental relief through better utilization of material goods, critics have become increasingly loud in recent years. Many people hoped that carsharing could lead to development away from ownership towards flexible use and thus more resource-efficient mobility. However, carsharing remains niche, and while many people like the idea in general, they appear to consider carsharing to not be advantageous as a means of transport in terms of cost, flexibility, and comfort. A key innovation that could elevate carsharing from its niche existence in the future is autonomous driving. This technology could help shared mobility gain a new boost by allowing it to overcome the weaknesses of the present carsharing business model. Flexibility and comfort could be greatly enhanced with shared autonomous vehicles (SAVs), which could simultaneously offer benefits in terms of low cost, and better use of time without the burden of vehicle ownership. However, it is not the technology itself that is sustainable; rather, sustainability depends on the way in which this technology is used. Hence, it is necessary to make a prospective assessment of the direct and indirect (un)sustainable effects before or during the development of a technology in order to incorporate these findings into the design and decision-making process. Transport research has been intensively analyzing the possible economic, social, and ecological consequences of autonomous driving for several years. However, research lacks knowledge about the consequences to be expected from shared autonomous vehicles. Moreover, previous findings are mostly based on the knowledge of experts, while potential users are rarely included in the research. To address this gap, this thesis contributes to answering the questions of what the ecological and social impacts of the expected concept of SAVs will be. In my thesis, I study in particular the ecological consequences of SAVs in terms of the potential modal shifts they can induce as well as their social consequences in terms of potential job losses in the taxi industry. Regarding this, I apply a user-oriented, mixed-method technology assessment approach that complements existing, expert-oriented technology assessment studies on autonomous driving that have so far been dominated by scenario analyses and simulations. To answer the two questions, I triangulated the method of scenario analysis and qualitative and quantitative user studies. The empirical studies provide evidence that the automation of mobility services such as carsharing may to a small extent foster a shift from the private vehicle towards mobility on demand. However, findings also indicate that rebound effects are to be expected: Significantly more users are expected to move away from the more sustainable public transportation, leading to an overcompensation of the positive modal shift effects by the negative modal shift effects. The results show that a large proportion of the taxi trips carried out can be re-placed by SAVs, making the profession of taxi driver somewhat obsolete. However, interviews with taxi drivers themselves revealed that the services provided by the drivers go beyond mere transport, so that even in the age of SAVs, the need for human assistance will continue – though to a smaller extent. Given these findings, I see action potential at different levels: users, mobility service providers, and policymakers. Regarding environmental and social impacts resulting from the use of SAVs, there is a strong conflict of objectives among users, potential SAV operators, and sustainable environmental and social policies. In order to strengthen the positive effects and counteract the negative effects, such as unintended modal shifts, policies may soon have to regulate the design of SAVs and their introduction. A key starting point for transport policy is to promote the use of more environmentally friendly means of transport, in particular by making public transportation attractive and, if necessary, by making the use of individual motorized mobility less attractive. The taxi industry must face the challenges of automation by opening up to these developments and focusing on service orientation – to strengthen the drivers’ main unique selling point compared to automated technology. Assessing the impacts of the not-yet-existing generally involves great uncertainty. With the results of my work, however, I would like to argue that a user-oriented technology assessment can usefully complement the findings of classic methods of technology assessment and can iteratively inform the development process regarding technology and regulation.

Hence, it is necessary to make a prospective assessment of the direct and indirect (un)sustainable effects before or during the development of a technology in order to incorporate these findings into the design and decision-making process. Transport research has been intensively analyzing the possible economic, social, and ecological consequences of autonomous driving for several years. However, research lacks knowledge about the consequences to be expected from shared autonomous vehicles. Moreover, previous findings are mostly based on the knowledge of experts, while potential users are rarely included in the research. To address this gap, this thesis contributes to answering the questions of what the ecological and social impacts of the expected concept of SAVs will be. In my thesis, I study in particular the ecological consequences of SAVs in terms of the potential modal shifts they can induce as well as their social consequences in terms of potential job losses in the taxi industry. Regarding this, I apply a user-oriented, mixed-method technology assessment approach that complements existing, expert-oriented technology assessment studies on autonomous driving that have so far been dominated by scenario analyses and simulations. To answer the two questions, I triangulated the method of scenario analysis and qualitative and quantitative user studies. The empirical studies provide evidence that the automation of mobility services such as carsharing may to a small extent foster a shift from the private vehicle towards mobility on demand. However, findings also indicate that rebound effects are to be expected: Significantly more users are expected to move away from the more sustainable public transportation, leading to an overcompensation of the positive modal shift effects by the negative modal shift effects. The results show that a large proportion of the taxi trips carried out can be re-placed by SAVs, making the profession of taxi driver somewhat obsolete. However, interviews with taxi drivers themselves revealed that the services provided by the drivers go beyond mere transport, so that even in the age of SAVs, the need for human assistance will continue – though to a smaller extent. Given these findings, I see action potential at different levels: users, mobility service providers, and policymakers. Regarding environmental and social impacts resulting from the use of SAVs, there is a strong conflict of objectives among users, potential SAV operators, and sustainable environmental and social policies. In order to strengthen the positive effects and counteract the negative effects, such as unintended modal shifts, policies may soon have to regulate the design of SAVs and their introduction. A key starting point for transport policy is to promote the use of more environmentally friendly means of transport, in particular by making public transportation attractive and, if necessary, by making the use of individual motorized mobility less attractive. The taxi industry must face the challenges of automation by opening up to these developments and focusing on service orientation – to strengthen the drivers’ main unique selling point compared to automated technology. Assessing the impacts of the not-yet-existing generally involves great uncertainty. With the results of my work, however, I would like to argue that a user-oriented technology assessment can usefully complement the findings of classic methods of technology assessment and can iteratively inform the development process regarding technology and regulation.}, language = {en}, urldate = {2021-04-15}, author = {Pakusch, Christina}, year = {2020}, keywords = {thesis}, } -

[BibTeX] [Abstract] [Download PDF]In 1991 the researchers at the center for the Learning Sciences of Carnegie Mellon University were confronted with the confusing question of “where is AI” from the users, who were interacting with AI but did not realize it. Three decades of research and we are still facing the same issue with the AItechnology users. In the lack of users’ awareness and mutual understanding of AI-enabled systems between designers and users, informal theories of the users about how a system works (“Folk theories”) become inevitable but can lead to misconceptions and ineffective interactions. To shape appropriate mental models of AI-based systems, explainable AI has been suggested by AI practitioners. However, a profound understanding of the current users’ perception of AI is still missing. In this study, we introduce the term “Perceived AI” as “AI defined from the perspective of its users”.

We want to distinguish between perceived stress and clinically-defined trauma, for which therapeutic interventions require direct personal contact with psychological experts. However, we also want to focus on the digital possibilities that currently exist to support establishing this kind of personal connection. Many refugees need to seek psychological help, but social, economic and cultural barriers hold them back. Our qualitative study with refugees, psychologists and volunteers provides insights into how refugees deal with their mental issues and the challenges they face in everyday life. We aim to show that ICT can play a major role in terms of addressing awareness and self-empowerment as an entry point for this vulnerable group. We also discuss the potential challenges and benefits of ICT for refugees seeking to recover their mental stability.

Human-Food-Interaction (HFI) looks into the interplay of humans, food and technology.

Through an analysis of the communal effort to actualize the project (video-calls, Telegram, wechange.de) and the content of the Telegram-Group for the chili-plant adopting parents and experts, we suggest some design implications for grassroots communities and sustainable food practice. In future research we intend an iterative design to support the community and its project, utilizing Holmgren’s 12 principles of permaculture design.

[BibTeX] [Abstract]In this position paper, we take a concept – or parts of it – and run away with it (Mol 2002) to explore its potential to better understand the non/appropriation of technologies by people in later life. We introduce the concept of the city as a machine for learning developed by Colin McFarlane (2011) in the field of urban studies. We identify elements we consider inspiring for the study of socio-technical systems, translate them to smaller entities of human-technology interactions and test their usability to analyze how older people in later life integrate digital technologies in their everyday lives. We do so from two distinct vantage points, i.e. empirical contexts: A participatory design project of a neighborhood platform and related privacy issues from the perspective of older tenants, and the introduction of a new automated emergency call system in seniors’ apartments in a serviced senior living facility. We conclude with the suggestion to understand the concept “machine for learning” as a normative notion and a claim to accept the challenge it implies.

IN Learning from Experience, Pages: 10
[BibTeX] [Abstract]The increasingly frequent occurrence of organizational crises exemplifies the need to strengthen organizational resilience. An example of business organizations is small and medium enterprises (SMEs) which contribute largely to the economic growth. But often, their limited resources (manpower, time, financial capital), organizational structure, focus on operational routines and less priority towards disaster resilience make them more vulnerable to crisis than bigger companies. The proposed solution addresses this dilemma by establishing a collaborative medium within the organization to improve disaster resilience by raising awareness and self-learning in employees without overburdening their constrained routines and resources. Our work in progress demonstrates a conceptual model of a learning aid (collaboration channel and a chatbot) that supports the pedagogical methodologies and employs them for enhancing learnability and awareness and elaborates the usability of interactive learning instilling disaster resilience in employees and hence in an organization.

Utilizing the case of food practices, we construct and analyze a network populated by the answers of 60 participants. Based on this network we suggest how to identify central elements and clusters as well as points for intervention within the overall network, but also within and in-between clusters of practices.

Existing approaches to design for appropriation and the development of sociable technologies that might support users seeking to understand how to make such technologies work in a specific practice, often lack appropriate user interfaces to explain the internal and environment-related behavior of a technology. By taking the example of 3D printing, we examine how augmented reality can be used as a novel human–machine interface to ease the way for hardware-related appropriation support. Within this paper we designed, implemented and evaluated a prototype called PrintARface, that extends a physical 3D printer by incorporating virtual components. Reflections upon the evaluation of our prototype are used to provide insights that foster the development of hardware-related appropriation support by encompassing augmented reality-based human–machine interfaces.

doi:10.1145/3404983.3405511
[BibTeX] [Abstract] [Download PDF]Diese Studie untersucht die Aneignung und Nutzung von Sprachassistenten wie Google Assistant oder Amazon Alexa in Privathaushalten. Unsere Forschung basiert auf zehn Tiefeninterviews mit Nutzern von Sprachassistenten sowie der Evaluation bestimmter Interaktionen in der Interaktions-historie. Unsere Ergebnisse illustrieren, zu welchen Anlässen Sprachassistenten im heimischen Umfeld genutzt werden, welche Strategien sich die Nutzer in der Interaktion mit Sprachassistenten angeeignet haben, wie die Interaktion abläuft und welche Schwierigkeiten sich bei der Einrichtung und Nutzung des Sprachassistenten ergeben haben. Ein besonderer Fokus der Studie liegt auf Fehlinteraktionen, also Situationen, in denen die Interaktion scheitert oder zu scheitern droht. Unsere Studie zeigt, dass das Nutzungspotenzial der Assistenten häufig nicht ausgeschöpft wird, da die Interaktion in komplexeren Anwendungsfällen häufig misslingt. Die Nutzer verwenden daher den Sprachassistenten eher in einfachen Anwendungsfällen und neue Apps und Anwendungsfälle werden gar nicht erst ausprobiert. Eine Analyse der Aneignungsstrategien, beispielsweise durch eine selbst erstellte Liste mit Befehlen, liefert Erkenntnisse für die Gestaltung von Unterstützungswerkzeugen sowie die Weiterentwicklung und Optimierung von sprachbasierten Mensch-Maschine-Interfaces.

Stevens, G. & Bossauer, P. (2020)Who do you trust: Peers or Technology? A conjoint analysis about computational reputation mechanisms
doi:10.18420/ecscw2020_ep01
[BibTeX] [Abstract] [Download PDF]Peer-to-peer sharing platforms are taking over an increasingly important role in the platform economy due to their sustainable business model. By sharing private goods and services, the challenge arises to build trust between peers online mostly without any kind of physical presence. Peer rating has been proven as an important mechanism. In this paper, we explore the concept called Trust Score, a computational rating mechanism adopted from car telematics, which can play a similar role in carsharing. For this purpose, we conducted a conjoint analysis where 77 car owners chose between fictitious user profiles. Our results show that in our experiment the telemetric-based score slightly outperforms the peer rating in the decision process, while the participants perceived the peer rating more helpful in retrospect. Further, we discuss potential benefits with regard to existing shortcomings of user rating, but also various concerns that should be considered in concepts like telemetric-based reputation mechanism that supplements existing trust factors such as user ratings.

[BibTeX] [Abstract] [Download PDF]As a result of aging societies, the prevalence of dementia, and accordingly the need for care is increasing. The use of information and communication (ICT)-based technologies may facilitate and promote a self-sustaining lifestyle for people with dementia and their caregivers. In this article, the authors provide results from a design study of an ICT-based system to support activity and mobility for people with dementia and their care-network. The authors investigated practices, attitudes and the social contexts of 26 people with dementia and their caregivers and designed an ICT-based prototype system that was evaluated afterwards in a four-month evaluation study. Here, the goal was to assess usability, user experience and acceptance and to analyze the effects of system usage on physical, cognitive and socio-emotional conditions of people with dementia and their caregivers. Our results indicate that the system supports people with dementia and their related caregivers partly during their social and daily activities and improves their quality of life. Furthermore, results suggest that motivation, collaboration and cooperation among the parties involved were increased by using the system. Integration and social embeddedness of ICT-based systems into the daily lives of people is the key for long-term and sustainable use. However, the involvement of caregivers and stakeholders seems to be an additional facilitating factor for daily life integration and may promote long-term use.

[BibTeX] [Abstract] [Download PDF]There is currently uncertainty in the research community as to how ICT can and should be designed in such a way that it can be convincingly integrated into the everyday lives of prison inmates. In this paper, we discuss a design fiction that closes this research gap. The descriptions and results of the study are purely fictitious. Excluded is the State of the Art as well as the description of the legal situation of prisons in Germany. The analysis of the fictional study data designed here thus refers to the real world in order to derive ethical guidelines and draw practical conclusions. It is our intention to use these results as a possible basis for further research. The paper presents results of an explorative study dealing with the design, development and evaluation of an AI-based Smart Mirror System, Prison AI 2.0, in a German prison. Prison AI 2.0 was developed for daily use and voluntarily tested by eight prisoners over a period of 12 months to gain insight into their individual and social impact, with an emphasis on its ability to actively support rehabilitation. Based on qualitative data, our findings suggest that intelligent AI-based devices can actually help promote such an outcome. Our results also confirm the valuable impact of (Psychosocial) ICT on the psychological, social and individual aspects of prison life, and in particular how prisoners used the Smart Mirror system to improve and maintain their cognitive, mental and physical state and to restore social interactions with the outside world. With the presentation of these results we want to initiate discussions about the use of ICT by prisoners in closed prisons in order to identify opportunities and risks.

[BibTeX] [Abstract] [Download PDF]Digital participation has become an important issue in modern societies, typically focusing on groups prone to marginalization. From this perspective, less attention has yet been paid to imprisoned persons. Many penitentiary systems are formally characterized by the basic requirement of resocialization. Accordingly, life in prison should be largely adapted to conditions outside and to fundamental social changes, which must be considered in designing the framework for prison systems. Still, the digital opening of the prison is debated controversially, not least due to anticipated security issues. Hence, to raise awareness about challenges for digital participation of prisoners, we conducted a knowledge-sociological analysis (SKAD) of the public discourse on the use of ICT by prison inmates in Germany. We thereby seek to advance knowledge and insights from social and organizational practice arising from the use of ICT in context of total institutions and create the basis for action from a socio-informatics perspective.

Weibert, A., Krüger, M., Aal, K., Salehee, S. S., Khatib, R., Randall, D. & Wulf, V. (2019)Finding Language Classes: Designing a Digital Language Wizard with Refugees and Migrants
IN Proceedings of the ACM on Human-Computer Interaction, Vol. 3, Pages: 116:1–116:23 doi:10.1145/3359218
[BibTeX] [Abstract] [Download PDF]For migrants and refugees, settling in a host country often proves hugely problematic. The ability to communicate marks a significant step in the process of resettlement. The current high number of migrants coming to Europe has therefore meant that the need to improve and increase the availability of language provision has become more pressing. Nevertheless, due to the complexity of financial and legal regulations and of policy restrictions, access to and information about available courses are in practice hard to find, and non-funded volunteer initiatives are scarcely visible at all. To address this problem, a newly developed language-course wizard provides orientation for refugees and migrants. Findings indicate that its visual representation is apt to span a broad range of cultural as well as educational backgrounds.

The ability to communicate marks a significant step in the process of resettlement. The current high number of migrants coming to Europe has therefore meant that the need to improve and increase the availability of language provision has become more pressing. Nevertheless, due to the complexity of financial and legal regulations and of policy restrictions, access to and information about available courses are in practice hard to find, and non-funded volunteer initiatives are scarcely visible at all. To address this problem, a newly developed language-course wizard provides orientation for refugees and migrants. Findings indicate that its visual representation is apt to span a broad range of cultural as well as educational backgrounds.

[BibTeX] [Abstract] [Download PDF]For over a decade researchers from the HCI community are taking social practices as a unit of design. While the first generation focused on social practice in isolation, more recent work argues for the interrelatedness of mutually influencing practices as the primary unit of analysis. We discuss these current approaches to motivate the notion of a network of practices. We argue that network theory presents a promising method to create more detailed and sophisticated models of social practices, that raise awareness about central elements and their connecting characteristics. Further on, our work identifies open questions that should be addressed in future work, to increase the benefits of the method.

Dieser Bezug auf den sozialen Wandel wird seitdem immer wieder perpetuiert: Der Wissenschaftszweig Soziologie hat seinen Ursprung in dem Erleben eines sozialen Wandels und widmet sich fortwährend der Frage, was eigentlich die Moderne auszeichnet, wie es zu diesem Wandel hin zur Moderne gekommen ist, und wie dieser Wandel erforscht werden kann.

However, these approaches are criticized for not paying enough attention to everyday consumption practices and hence for not being successful in the long term. Therefore, we argue for a broader perspective on studying the role(s) of digital media supporting people in their transition towards more sustainable food consumption. To understand such roles, we conducted semi-structured interviews with 9 vegans. Our findings highlight an intensive use of (digital) media, especially in the early phase of changing consumption practices. Instead of gamification or persuasive design, media triggers initial irritation, provides information to develop a vegan-specific consumption knowledge and connects like-minded people.

[BibTeX] [Abstract] [Download PDF]While crowds online are increasingly used for data gathering and problem solving, the relationships and structures within these processes remain largely unexamined. For understanding the usage of crowdsourcing and to design appropriate technologies and processes, it is important to understand how different tools support relationships in these contexts. Based on an extensive literature review of existing crowdsourcing tools and practices, we contribute with the development of a typology of alienation in crowdsourcing by using Marx’s theory of alienation. The theory serves as a lens to compare and contrast a number of currently available tools for crowdsourcing, focusing on how relationships between participants are supported and capitalized within the tool. We show how different types of crowdsourcing practices can be described in terms of alienation where the producer, the producers, the consumers, and products are connected in different modes of participation. This systematical application of Marx theory of alienation provides a way to compare the technical support for social relationships in a number of platforms used for crowdsourcing.

Although ICT plays an increasingly large role in crisis response and management, in-depth studies on crisis apps and similar technology in the context of an emergency have been missing. Based on responses by 1024 participants in Germany, we examine the diffusion, usage, perception and adoption of mobile crisis apps as well as required functions and improvements. We conclude that crisis apps are still a little-known form of disaster ICT, but have potential for enhancing communication, keeping users up to date and providing a more effective crisis management as supplement to other media channels dependent on different underlying infrastructures. However, they should be adaptable to user characteristics, consider privacy, allow communication and offer valuable information to raise awareness of potential disasters without creating an overload. Also, the familiarity with and trust in crisis apps should be addressed to maximize their beneficial impact on crisis communication and management. We discuss further implications as well as directions for future research with larger target groups and specific usage scenarios.

Hence, methodologies are needed that promote human-robot collaboration and allow the robot to learn from its human mentor to become more autonomous and reliable. This demo illustrates an environment for such human-robot collaboration that provides an infrastructure for SR manipulation and teaching. The basic idea is that the robot becomes an apprentice that learns new skills by observing a trained human mentor that performs relevant tasks in the service domain by operating the robot. By observation and collaboration, the SR gradually becomes more autonomous and capable to carry out relevant healthcare tasks.

Today, more than ever before, personal information is being used by companies of all types for a wide variety of purposes. To limit this, the General Data Protection Regulation (GDPR) aims to provide consumers with tools to control data collection and processing. What this right concretely means, which types of tools companies have to provide to their customers and in which way, is currently uncertain because precedents from case law are missing. Contributing to closing this gap, we turn to the example of loyalty cards to supplement current implementations of the right to claim data with a user perspective. In our hands-on approach, we had 13 households request their personal data from their respective loyalty program. We investigate expectations of GDPR in general and the right to access in particular, observe the process of claiming and receiving, and discuss the provided data takeouts. One year after the GDPR has come into force, our findings highlight the consumer’s expectations and knowledge of the GDPR and in particular the right to access to inform design of more usable privacy enhancing technologies.

Simonsen, J., Karasti, H. & Hertzum, M. (2019)Infrastructuring and Participatory Design: Exploring Infrastructural Inversion as Analytic, Empirical and Generative
IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-019-09365-w
[BibTeX] [Abstract] [Download PDF]The participatory design of CSCW systems increasingly embraces activities of reconfiguring the use of existing interconnected systems in addition to developing and implementing new. In this article, we refer to such activities of changing and improving collaboration through the means of existing information infrastructures as infrastructuring. We investigate a relational perspective on infrastructuring and provide an overview and a detailed account of a local infrastructuring process by tracing the concrete relations that emerged. The elusive quality of information infrastructures as being invisible is analyzed through the notion of infrastructural inversion. Infrastructural inversion is the gestalt switch of shifting attention from the activities invisibly supported by an infrastructure to the activities that enable the infrastructure to function and meet desired needs for collaborative support. Initially, infrastructural inversion was conceived as a conceptual-analytic notion, but recent research has also positioned it as an empirical-ethnographic and generative-designerly resource. In this study, we rely on all of these stances and contribute to the generative-designerly position. We explain the notion of infrastructural inversion and describe how it is distinct from the CSCW concept of articulation work. The context of the analysis includes a participatory design project that sought to reduce patients‘ fasting time prior to surgical operations by improving the interdepartmental coordination at a hospital. The project revealed the webs of relations and interdependencies in which fasting time is inscribed at the local level as well as regionally, nationally, and beyond. We pursue the relations, trace their connectedness across multiple scopes, and show how the process alternated between empirical and analytic activities of exploring relations and design-oriented activities of reaching closure. Our analysis shows that the notion of infrastructural inversion can enrich participatory design: Infrastructural inversion embraces the exploratory activities of tracing relations, while the design agenda drove the need for reaching closure. We conclude by discussing lessons learned for infrastructuring and for participatory design that engages with infrastructuring.

Rüller, S., Aal, K. & Holdermann, S. (2019)Reflections on a Design Case Study – (Educational) ICT Intervention with Imazighen in Morocco
Proceedings of the 9th International Conference on Communities & Technologies – Transforming Communities. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 172–177 doi:10.1145/3328320.3328406
[BibTeX] [Abstract] [Download PDF]This case study describes the establishment of an educational ICT-intervention, a Computer Club, in the High Atlas, Morocco. We will first give an overview of the general approach and the first intervention. Then, we go into depth of the following trip, 15 months after the opening of the Computer Club. We describe the concerns to address and activities planned in advance based on the knowledge we acquired during the first intervention as well as on the insights we gained during this trip and discuss how much has changed. Reflections of these experiences discuss the importance of involving local partners, mitigating the power dynamics to build a trustful relationship and the impact of the intervention on the valley. We conclude with the most recent developments which involved a visit of the local partners to Germany to create a common understanding of the club approach.

Hoffmann, S., de Carvalho, A. F. P., Abele, D., Schweitzer, M., Tolmie, P. & Wulf, V. (2019)Cyber-Physical Systems for Knowledge and Expertise Sharing in Manufacturing Contexts: Towards a Model Enabling Design
IN Computer Supported Cooperative Work (CSCW), Vol. 28, Pages: 469–509 doi:10.1007/s10606-019-09355-y
[BibTeX] [Abstract] [Download PDF]Cyber-physical systems (CPS) are currently attracting a great deal of attention as a part of the discourse surrounding the fourth industrial revolution. Thus far, the chief focus has been upon complex architectures for supply chain-wide data exchange between intelligent machines. Here, however, we take a very different tack by examining the support CPS may offer for the exchange and acquisition of knowledge-intensive human practices in the context of manual set-up processes on modern production machines. The paper offers contributions to both CSCW and the ongoing development of CPS in three ways. Firstly, it presents a detailed empirical study of knowledge and expertise sharing practices in a production environment. Secondly, the results of this study are used as the basis of an over-arching model that was developed with the express purpose of facilitating design. Finally, CPS-based technical possibilities are matched to the practice-relevant knowledge and expertise sharing requirements captured within the model.
