Lawo, D., Neifer, T., Esau, M. & Stevens, G. (2021)Buying the ‘Right’ Thing: Designing Food Recommender Systems with Critical Consumers
New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–13 doi:10.1145/3411764.3445264
[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.

Pakusch, C., Meurer, J., Tolmie, P. & Stevens, G. (2020)Traditional taxis vs automated taxis – Does the driver matter for Millennials?
IN Travel Behaviour and Society, Vol. 21, Pages: 214–225 doi:10.1016/j.tbs.2020.06.009
[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.

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.

Jakobi, T., Stevens, G., von Grafenstein, M., Pins, D. & Boden, A. (2020)Die nutzerInnenfreundliche Formulierung von Zwecken der Datenverarbeitung von Sprachassistenten
[BibTeX] [Abstract] [Download PDF]
2019 wurde bekannt, dass mehrere Anbieter von Sprachassistenten Sprachaufnahmen ihrer NutzerInnen systematisch ausgewertet haben. Da in den Datenschutzhinweisen angegeben war, dass Daten auch zur Verbesserung des Dienstes genutzt würden, war diese Nutzung legal. Für die NutzerInnen stellte diese Auswertung jedoch einen deutlichen Bruch mit ihren Privatheitsvorstellungen dar. Das Zweckbindungsprinzip der DSGVO mit seiner Komponente der Zweckspezifizierung fordert neben Flexibilität für den Verarbeiter auch Transparenz für den Verbraucher. Vor dem Hintergrund dieses Interessenkonflikts stellt sich für die HCI die Frage, wie Verarbeitungszwecke von Sprachassistenten gestaltet sein sollten, um beide Anforderungen zu erfüllen. 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. Unsere Ergebnisse über von Nutzern wahrgenommene Risiken erlauben dabei Rückschlüsse auf die anwenderfreundliche Gestaltung von Verarbeitungszwecken im Sinne einer Design-Ressource.

Jakobi, T., Stevens, G., von Grafenstein, M., Pins, D. & Boden, A. (2020)User-friendly formulation of data processing purposes of voice assistants: a user perspective on the principle of purpose limitation
New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 361–372 doi:10.1145/3404983.3405588
[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.

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.

[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. We discuss implications of our results for future work in service domains and emphasize a shift of focus from full robot automatization to human-robot collaboration forms.

[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.

Pakusch, C., Bossauer, P., Meurer, J. & Stevens, G. (2020)Walking the Tightrope: Designing Autonomous Vehicles for Comfort and for Sustainability
Given current traffic problems, transport-induced air pollution and climate damaging emissions, researchers are investigating potentials of autonomous vehicles (AVs) to contribute to a more sustainable mobility. Some studies, however, indicate that the introduction of AVs may cause rebound effects that could further harm the environment such unintended modal shifts.

Bossauer, P., Neifer, T., Stevens, G. & Pakusch, C. (2020)Trust versus Privacy: Using Connected Car Data in Peer-to-Peer Carsharing
New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–13 doi:10.1145/3313831.3376555
[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.

[BibTeX] [Abstract] [Download PDF]Currently, there is a broad range of studies dealing with the design and visualization of energy consumption data for the domestic and increasingly for the office context. 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.

IN Sustainability, Vol. 12, Pages: 5184 doi:10.3390/su12125184
[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’.

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.

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.

[BibTeX] [Abstract] [Download PDF]For over a decade, researchers from the practice-centered computing community are taking social practices as a unit of design. While the first generation focused on a social practice in isolation, more recent work argues for the (inter-)connections of mutually influencing practices as the primary unit of design. We discuss these current approaches to motivate the notion of a network of practices. 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. Based on this, our work critically discusses how an understanding of practices as a network could improve practice-based research and design.

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”.

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.

New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–4 doi:10.1145/3363384.3363470
[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.

[BibTeX] [Abstract] [Download PDF]Loyalty programs are early examples of companies commercially collecting and processing personal data. 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.

New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 889–891 doi:10.1145/3340764.3345374
[BibTeX] [Abstract] [Download PDF]Natural and reliable application of service robots (SR) in service domains, for instance health service or elderly care, is currently not possible and full autonomy and automatization of SR is still in far distance. 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.

[BibTeX] [Abstract] [Download PDF]Previous attempts of the HCI community to reduce food waste or the carbon footprint, primarily relied on persuasive design. 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.

We show how these methods are adopted in the context of autonomous driving research and dis-cuss their strengths and weaknesses. Due to the complexity of the topic, we will show that mixed method approaches will be suitable to explore the impact of autonomous driving on different levels: the individual, the social interaction and society.

Castelli, N., Ogonowski, C., Jakobi, T., Stein, M., Stevens, G. & Wulf, V. (2017)What happened in my home?: An End-User Development Approach for Smart Home Data Visualization
Smart home systems change the way we experience the home. While there are established research fields within HCI for visualizing specific use cases of a smart home, studies targeting user demands on visualizations spanning across multiple use cases are rare. Especially, individual data-related demands pose a challenge for usable visualizations. To investigate potentials of an end-user development (EUD) approach for flexibly supporting such demands, we developed a smart home system featuring both pre-defined visualizations and a visualization creation tool. To evaluate our concept, we installed our prototype in 12 households as part of a Living Lab study. Results are based on three interview studies, a design workshop and system log data. We identified eight overarching interests in home data and show how participants used pre-defined visualizations to get an overview and the creation tool to not only address specific use cases but also to answer questions by creating temporary visualizations.

Wulf, V., Pipek, V., Rohde, M., Stevens, G. & Randall, D. (2017)Socio Informatics – A practice‐based perspective Proposed Table of Contents
[BibTeX] [Abstract] [Download PDF]
The book will propose a practice‐based approach to socio‐ informatics, a research paradigm in applied CS which suggests building a corpus of contextually situated design case studies. This practice‐based approach builds substantially on work in CSCW, but notably on the socio‐ technical approaches sometimes associated with European CSCW. Our position is that a major lacuna in CSCW thus far has been the absence of adequate means to deal with the problem of transferability of insight across different case studies. That is, although a growing corpus of studies has demonstrated the importance of socio‐ technical insights, conceptual and theoretical competition has restricted their value. We aim to begin the process of rectifying this situation by proposing a systematic approach to the problem of interdisciplinarity. The last twenty five years have seen a small revolution in our approach to the understanding of new technology. It has become a founding assumption of CSCW that in the future, if not already, most computer applications will be socially embedded in the sense that they will become infrastructures for the development of the social practices which they are designed to support. This will be true in an ever increasing variety of domains and living conditions. Assuming that IT artifacts have to be understood in this socio‐technical way, traditional design criteria in CS (performance, correctness, stability or usability) need to be supplemented by methods and perspectives which illuminate the way in which technology and practice are mutually elaborating. This has involved, inter alia, new methodologies for the investigation of patterns of use and the gathering of requirements (including ethnographic work; ‘living labs’ and so on); new methodologies for design (methodologies which place flexibility and user involvement at the centre) and new approaches to the product lifecycle (which recognize the complex and long term nature of appropriation of technology by users and hence implicate a different understanding of evaluation). Nevertheless, these developments remain piecemeal. In our view, the field has to a degree been restricted in its development by a competition between theoretical perspectives largely founded in their disciplinary origins in sociology and psychology. The growth of a systematic and rigorous approach to practice‐ based, or human‐centred, computing requires new foundations. These foundations, we suggest, will be predicated on the resolution of a number of issues: 1. A clearer understanding of what we mean by practice and how it is socially embedded. 2. A more nuanced view of the different ways in which processes of empirical investigation and of construction may be linked to each other. 3. A better understanding of the way in which new design methodologies link to investigative approaches and of effective mechanisms for supporting stakeholder involvement. 4. A systematic approach to the use of technology which extends from early investigation into domains of practice through to investigation of the ways in which practices become embedded in social and organizational life. Our proposal, then, is for an edited book structured to reflect these issues and concerns. More specifically, this will be done by linking key methodological chapters to empirical chapters which illustrate these themes. To elaborate on this, the book will be divided into four parts. The first one elaborates on the theoretical foundations of design‐related work, specifically on the concepts of practice, design and appropriation. In the second part, different methodological approaches and how best to utilize them in design‐related enquiry will be presented and discussed. Again, the focus will be on the tailoring of investigative strategies for specific kinds of design problem (business ethnography, grounded design, integrated organization and technology development, mobility, cross‐ cultural work, inter‐organizational collaboration). The third part presents a sample of design case studies originated in different social and organizational contexts which can be understood as exemplars of more general problems. That is, each will orient in turn to the problem of comparability and ways in which cross‐cutting issues can be identified. Design case studies are understood as investigations into the practices before and after introducing the IT artifacts and the design process in support of these practices. They develop on a three phase research model, linking: empirical prestudy, the IT design and the investigation into its appropriation. We argue that design case studies or fractals of them should become a key element in Socio Informatics. In this sense, ‘Socio Informatics’ is epistemologically distinct from traditional approaches to CS in the sense that it creates highly context specific results and its findings are only valid in the context of their emergence. CS and even the traditional approaches to Human Centered Computing assume a context‐independent validity for these formal, algorithmic and design‐oriented findings. If research‐ findings are context‐specific we need to find new ways to reason about their transferability.

[BibTeX] [Abstract] [Download PDF]The introduction of IT has changed the way we live in many ways. Historically, it can even be argued that socially embedded applications of information technology challenge and change practices to an extent rarely seen before with any other type of technological artefacts. If these IT artefacts have strong and recurrent impacts on people’s lives, we need to reconsider design practice artefacts which allow for anticipating use practices and bring together inspirational creativity with evaluative methods. Approaches such as Participatory Design (Greenbaum and Kyng 1991) and User‐Driven Innovation (von Hippel 2005) have already significantly increased the level of involvement of users and their fields of practice into IT development and have strengthened the role of ethnographic methods as well as the importance of methods providing direct user feedback. But even a strong component of domain analysis or user participation does not warrant an accurate anticipation of the changes in social practices resulting from new technological artefacts or infrastructures. Moreover, the immaterial nature of software contributes to its application beyond the originally intended context. The material and social foundations of IT usage have significantly changed over the past two decades. Technologically, the standardization of communication interfaces, the increase of bandwidth and speed of internet connections and their ubiquitous availability have connected more and more devices with each other. At a social level this has also created stronger connections between professional and private domains and practices, offering new room to adapt these practices and re‐negotiate their relations and compositions. These developments have made us now look at ecosystems (Draxler et al. 2015) or infrastructures (Star and Ruhleder 1996) of technology‐based practices. With regard to methods, EUSSET’s research agenda would benefit from a convergence of a broadly defined research program which looks at technology development as well as scenarios of usage and accumulates results in various ways, bridging the gap between a simple ‘technology‐in‐practice’ perspective and a ‘technology‐based practice change’ perspective. We need to consider how to carefully transfer emerging design concepts, IT artefacts, and pattern of appropriation derived in a specific context to other fields of application. We also need to better understand how to transfer findings gained with the design and appropriation of one artefact towards that of another, related one. In this paper we will outline a research program, called practice‐based computing, which suggests collecting a corpus of highly contextualized design case studies and supports the transferability of insights by comparative concept building on top of these cases.

[BibTeX] [Abstract] [Download PDF]The high complexity of knowledge-intensive work such as software development makes it beneficial to have spaces for formal and informal articulation work. Existing information systems (IS) tend to treat these different aspects of coordination separately, resulting in problems of awareness and coordination. To bridge this gap, we present the concept of Articulation Spaces which combines aspects of Coordination Mechanisms and Common Information Spaces (CIS) in order to provide a room for mediating between the formal and informal aspects of coordination. Based on a design study in the form of a lightweight public display that has been tested in a medium-sized German software company, we show how Articulation Spaces provide information for meta-coordination, encourage ad-hoc coordination and support decision-making processes. Our findings provide insights into the design of support systems for flexible and coordination-intensive contexts such as software development work. Copyright © 2014 ACM.

IN Interacting with Computers, Vol. 27, Pages: 1–26 doi:10.1093/iwc/iwu009
[BibTeX] [Abstract] [Download PDF]One of the great societal challenges that we face today concerns the move to more sustainable patterns of energy consumption, reflecting the need to balance both individual consumer choice and societal demands. In order for this ‘energy turnaround’ to take place, however, reducing residential energy consumption must go beyond using energy-efficient devices: More sustainable behaviour and lifestyles are essential parts of future ‘energy aware’ living. Addressing this issue from an HCI perspective, this paper presents the results of a 3-year research project dealing with the co-design and appropriation of a Home Energy Management System (HEMS) that has been rolled out in a living lab setting with seven households for a period of 18 months. Our HEMS is inspired by feedback systems in Sustainable Interaction Design and allows the monitoring of energy consumption in real-time. In contrast to existing research mainly focusing on how technology can persuade people to consume less energy (‘what technology does to people’), our study focuses on the appropriation of energy feedback systems (‘what people do with technology’) and how newly developed practices can become a resource for future technology design. Therefore, we deliberately followed an open research design. In keeping with this approach, our study uncovers various responses, practices and obstacles of HEMS use. We show that HEMS use is characterized by a number of different features. Recognizing the distinctive patterns of technology use in the different households and the evolutionary character of that use within the households, we conclude with a discussion of these patterns in relation to existing research and their meaning for the design of future HEMSs.

[BibTeX] [Abstract] [Download PDF]Residential and commercial buildings are responsible for about 40\% of the EU’s total energy co n- sumption. However, conscious, sustainable use of this limited resource is hampered by a lack of visibility and materiality of consumption. One of the major challenges is enabling consumers to make informed decisions about energy consumption, thereby supporting the shift to sustainable a c- tions. With the use of Energy-Management-Systems it is possible to save up to 15\%. In recent years, design approaches have greatly diversified, but with the emergence of ubiquitous- and co n- text-aware computing, energy feedback solutions can be enriched with additional context info r- mation. In this study, we present the concept “ room as a context ” for eco-feedback systems. We investigate opportunities of making current state- of-the-art energy visualizations more meaningful and demonstrate which new forms of visualizations can be created with this additional info r- mation. Furthermore, we developed a prototype for android-based tablets, which includes some of the presented features to study our design concepts in the wild.

[BibTeX] [Abstract] [Download PDF]This paper presents results of a three-year research project focused on the emplacement of Home Energy Management Systems (HEMS) in a living lab setting with seven households. The HEMS used in this study allowed householders to monitor energy consumption both in realtime and in retrospective on the TV and on mobile devices. Contrasting with existing research focused on how technology persuades people to consume less energy, our study uses a grounded approach to analyze HEMS emplacement. As an important result, we present here the issue of ‘energy literacy’. Our study reveals that, by using HEMS, participants became increasingly literate in understanding domestic electricity consumption. We discuss the role HEMS played in that process and how the acquired literacy changed energy consumption patterns. We conclude that literacy in energy consumption has value on its own and explain how eco feedback system designs can benefit from this understanding. Copyright © 2013 ACM.

[BibTeX] [Abstract]News reports of Internet-based security breaches, identity theft, fraud, and other dangers may increase the perceived risk and decrease the perceived benefits of using electronic services (or e-services). We examine whether interactivity serves as a means to diminish the perceived risks and increase the perceived benefits of using e-services. To examine interactivity‟s influence on consumers‟ perceptions, we conducted a laboratory experiment using a simulated web-based, online payment system. When compared to a non-interactive preview of an online payment system, we found that consumers who used an interactive e-service simulation reported higher perceived involvement and authenticity as well as higher intangibility and risks of e-services. Further, we found that interactivity moderated relationships such that consumers were more likely to report higher intentions to use e- services. The paper concludes with implications for research and practice

[BibTeX] [Abstract]Since the 1990s, the forms of production, distribution, configuration and appropriation of software have changed fundamentally. Nowadays, software is often embedded in software ecosystems, i.e. in complex interrelations between different stakeholders who are connected by a shared technological platform. In our paper, we investigate how small software teams deal with the challenges of appropriating and configuring software in the Eclipse ecosystem for their daily work. We empirically identify three different approaches for dealing with appropriation in software ecosystems which are represented by the “ideal types” lone warrior, centralized organization, and collegial collaboration. Based on a discussion of these strategies and the underlying appropriation practices we found in the field, we suggest theoretical and practical implications for supporting appropriation in software ecosystems.

[BibTeX] [Abstract] [Download PDF]Engaging end-users and user communities to take an active part in the co-creation, evolution, and appropriation of modern, interactive systems has become an increasingly important issue over the last years. Bringing together existing research and experiences as well as new challenges such as long-term, large-scale, or highly distributed stakeholders has led to the notion of Open Design Spaces (ODS) to frame and reflect current developments of distributed co-design. Several, formerly often separated strands of research covering different aspects of these challenges have emerged and led to a growing community of researchers and practitioners building on concepts such as Participatory Design, Meta-Design, and End-User Development. Building on two successful predecessors on the topic with more than 50 international researchers and practitioners, the workshop at DIS 2010 focuses particularly on social aspects and community co-creation in Open Design Spaces. © 2010 ACM.

[BibTeX] [Abstract]Sport is a domain full of movement-based interactions. These interactions typically have positive health effects as well as an impact on social bonding. We have investigated ways in which computer augmented devices can lead to new sport experiences and explored opportunities to combine physical activities with remote social bonding. Three prototypes have been implemented which showcase movement-based interaction in sports. “Breakout for Two” allows geographically distant users to play a physically exhausting ball game together. “\{FlyGuy\}” gives users a hang-glide experience controllable through body movement. “Push’N’Pull” uses isometric exercise equipment over a network to encourage users to complete a cooperative game whilst performing intense muscular actions. A comparison of these applications shows that such movement-based interaction in a networked environment allows players in different locations to achieve a work out and also to socialize. Based on these projects, we conclude with practical design implications for future Exertion Interfaces.

In this paper we describe how to bridge between ethnically defined communities by means of computer-supported project work. Our approach is grounded in socio-cultural theories of learning, especially Community of Practice (CoP). To evaluate our approach, we have built up a computer club in a multi cultural neighbourhood of the city of Bonn. Parents and children of mainly German and Turkish origin work jointly to create multimedia artefacts. These artefacts represent aspects of the neighbourhood’s recent history. The paper describes the project and its theoretical background. We also provide empirical findings to evaluate our approach.

Ziel unserer Forschung ist es, unter Berücksichtigung der Aspekte nutzerorientierte Gestaltung, Anthropomorphismus der Interaktion und Zuverlässigkeit der bereitgestellten Information zu ermitteln, wie eine erfolgreiche Interaktion zwischen Menschen und Sprachassistenten gelingen kann. Die Herausforderung dabei ist unter anderem, dass Anwendungen ineinandergreifen und eine komplexe und vor allem flexible Form der Interaktion mittels Sprache erfordern.
