Berkholz, J., Esau, M. & Stevens, G. (2023)Digitale Geschmacksvermittlung: Work-in-Progress Studie zur Entwicklung eines Nutzer:innen-zentrierten Designs zur Steigerung der Konsumkompetenz
IN Mau, G., Schuhen, M. & Froitzheim, M. (Eds.), Verbraucherforschung zwischen Empowerment und Verletzlichkeit: Verbraucherrelevante Zukunftsfragen aus der Perspektive der Wissenschaft und Praxis Wiesbaden doi:10.1007/978-3-658-41247-0_6
[BibTeX] [Abstract] [Download PDF]Trotz der immer weiter wachsenden Nachfrage von Online-Shopping-Möglichkeiten, ist der digitale Einkauf von frischen Lebensmitteln für viele Verbraucher:innen wenig attraktiv. Neben grundsätzlichen Barrieren, die die Nutzung des E-Commerce betreffen, stellt die fehlende Möglichkeit die tatsächlichen Produkte zu sehen und anzufassen ein Hindernis dar. Durch unsere Work-in-Progress Studie konnten wir mit Hilfe zweier Fokusgruppen und der Methode der Zukunftswerkstatt herausfinden, wie ein alternativer Ansatz unter Einbezug der Verbraucher:innen gestaltet werden könnte. Aus den prototypischen Zeichnungen der Teilnehmer:innen wurde deutlich, dass die Aspekte der Personalisierung und Transparenz im Vordergrund für sie stehen. In der Umsetzung dieser Ideen sehen wir gleichwohl eine Möglichkeit die Konsumkompetenz zu stärken und Lebensmittelverschwendung vorzubeugen.

Lawo, D., Neifer, T., Esau, M. & Stevens, G. (2023)Human-Centred Digital Sovereignty: Explorative Conceptual Model and Ways Forward
Computer-Human Interaction Research and Applications. Cham, Publisher: Springer Nature Switzerland, Pages: 84–103 doi:10.1007/978-3-031-49368-3_6
[BibTeX] [Abstract]In recent years, both authoritarian and democratic states have started using the term digital sovereignty as a basis for their digital policies. Although the interpretations and resulting policies may differ, the autonomy and sovereignty of individuals and their communities are at stake. Current political discourses mainly focus on governmental and corporate actors and their aspirations to control the digital sphere. Given the importance of this term, scholars in our community have begun to engage with the discourse. However, there is still a lack of dissemination, coming with a lack of conceptual models to explain, explore, and research human-centred digital sovereignty. Inspired by claims for human-centred digital sovereignty, this paper takes up the discourse and creates an explorative conceptual model that aims to guide early research within HCI, support an understanding of the field, and helps to identify relevant cases. Moreover, we discuss key challenges and potential ways forward.

Esau, M., Lawo, D., Neifer, T., Stevens, G. & Boden, A. (2022)Trust your guts: fostering embodied knowledge and sustainable practices through voice interaction
IN Personal and Ubiquitous Computing doi:10.1007/s00779-022-01695-9
[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.

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.

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. Our Smart Mirror, enhanced by digital qualities, supports meaningful activities and makes the bathroom more appealing. Thereby, we discuss domestic technology design beyond automation.

Lawo, D., Esau, M., Neifer, T. & Stevens, G. (2021)Probing Integrated Household Information Systems for Integrated Food Practices
, Publisher: SciTePress, Science and Technology Publications, Pages: 15–23
[BibTeX] [Abstract] [Download PDF]Recent publications propose concepts of systems that integrate the various services and data sources of everyday food practices. 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.

, Publisher: SCITEPRESS – Science and Technology Publications, Pages: 183–194
[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.

Proceedings of the 2021 CHI Conference on Human Factors in Computing Systems. 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.

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.

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’.

Lawo, D., Engelbutzeder, P., Esau, M. & Stevens, G. (2020)Networks of Practices: Exploring Design Opportunities for Interconnected Practices
doi:10.18420/ecscw2020_ep03
[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.

doi:10.18420/muc2020-ws111-369
[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 then present our preliminary results from deep-interviews with 50 AItechnology users, which provide a framework for our future research approach towards a better understanding of PAI and users’ folk theories.

We then present our preliminary results from deep-interviews with 50 AItechnology users, which provide a framework for our future research approach towards a better understanding of PAI and users’ folk theories.}, language = {en}, urldate = {2021-04-15}, author = {Alizadeh, Fatemeh and Esau, Margarita and Stevens, Gunnar and Cassens, Lena}, year = {2020}, note = {Accepted: 2020-08-18T15:19:49Z Publisher: Gesellschaft für Informatik e.V.}, }

Lawo, D., Engelbutzeder, P., Esau, M. & Stevens, G. (2019)Towards a Network of Practices: Identifying Central Elements to Inform Design
Proceedings of the Halfway to the Future Symposium 2019. 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.

Aal, T., Taugerbeck, S., Esau, M., Aal, K., Tolmie, P. & Wulf, V. (2019)The Social Mile – How (Psychosocial) ICT can Help to Promote Resocialization and to Overcome Prison
IN Proceedings of the ACM on Human-Computer Interaction, Vol. 3, Pages: 248:1–248:31 doi:10.1145/3370270
[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.

Lawo, D., Esau, M. & Stevens, G. Same, but Different Data – Towards Integrated Food & Household Services
, Pages: 5
[BibTeX] [Abstract]While information about our food consumption behavior becomes more and more available through different digitalization trends within this domain, such as food related apps or smart kitchen devices, information remains captured in silos and can therefore not be used for usable and meaningful customer applications. This research in progress presents the approach of integrated food & household services, that are based on best practices of the integrated information systems domain and yet existing integrated fitness & health services, such as GoogleFit or Apple HealthKit.
