Jahn, L., Engelbutzeder, P., Michel, L. K., Prost, S., Twidale, M. B., Randall, D. & Wulf, V. (2025)Blending Code and Cause: Understanding the Dynamic Motivations of Volunteer Developers in community-driven FOSS projects
Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–17 doi:10.1145/3706598.3713416
[BibTeX] [Abstract] [Download PDF]Understanding the motivations of volunteer developers is crucial for the HCI community as it seeks to design sustainable, community-driven digital platforms. This study explores the dynamics of motivation among volunteer developers in the Foodsharing.de platform, a grassroots movement focused on reducing food waste through community engagement. By investigating the evolving motivations and challenges faced by these developers, our research highlights the unique blend of personal passion, technical skill, and social commitment that sustains their long-term involvement. Through interviews, observations, and participatory research, we uncover how developers balance their commitment to Free and Open Source Software (FOSS) with the platform’s socio-ecological mission. Our findings emphasize the importance of fostering a supportive community, clear governance, and effective infrastructuring to manage motivation, frustration, and expectations. We discuss strategies to enhance volunteer retention, such as improving feedback mechanisms and recognizing contributions, which are critical for the sustainability of volunteer-driven platforms.

Mouratidis, M., Rosa Cardoso, C., Engelbutzeder, P., Tolmie, P., Aal, K. K. & Wulf, V. (2025)Designing for Resilience: Fostering Ponds of Stability with Computer Clubs in Palestine

[BibTeX] [Abstract] [Download PDF]Addressing the complexities of conflict-affected regions remains a critical challenge for Human-Computer Interaction (HCI). This paper examines the establishment of computer clubs in Palestinian refugee camps, where efforts to create sustainable interventions weighed against the instability of prolonged conflict. To capture this dynamic, we introduce the notion of ‘adaptive ponds of stability,’ which extends the ‘tech public of erosion’ framework [12]. While the latter emphasizes systemic depletion of socio-technical infrastructures, adaptive ponds of stability highlight efforts to foster temporary spaces of resilience. The clubs became hubs of learning, respite, and collaboration—offering moments of routine and empowerment amidst disruption. Reflecting on this, we advocate for a paradigm shift from sustainability to resilience as the primary design goal in unstable contexts. Our findings emphasize adaptability, local agency, and cultural sensitivity that respond dynamically to context-specific challenges, offering a nuanced approach to advancing HCI interventions in conflict-affected settings.

IN Interacting with Computers, Pages: iwae055 doi:10.1093/iwc/iwae055
[BibTeX] [Abstract] [Download PDF]Interconnected global crises have emphasized the need for alternative visions of the future, making transformative action urgent. Consequently, Sustainable Human–Computer Interaction (SHCI) has seen growing interest in exploring means to support radical and sustainable change, starting with grassroots, community-driven endeavors. This study explores the concept of Utopian Design Space (UDS) in the context of surplus redistribution in grassroots communities. The objective is to understand how practical concerns and transformative ambitions intersect, creating spaces that foster sharing and caring practices. Through action-oriented research, we examine six local projects, highlighting ICT’s role in these initiatives. Our findings highlight the challenges and opportunities in managing values, scalability, sustainability and inclusivity within UDSs. We discuss how aligning ICT with community practices can foster socio-technical innovation and support transformative change, introducing the notion of prefigurative technology. These insights can help us envisage design spaces that foster utopian ideas like equitable resource distribution and generalized reciprocity.

Ntouros, V., Vlachokyriakos, V. & Engelbutzeder, P. (2024)More than Foodsaving Machines: Insights from Communities Fighting Food Waste in the Digital Age
IN Interacting with Computers, Pages: 16 doi:10.1093/iwc/iwae043
[BibTeX] [Abstract] [Download PDF]Grassroots initiatives promoting sharing-for-community are viewed as contributing to the transition towards a more socially equitable and environmentally sustainable world. However, along with other challenges, they often encounter technological barriers. In this article we report on our engagement with a number of self-organised foodsaving and sharing communities active in Europe which use the open-source platform Karrot to coordinate their activities. Our aim has been to explore the use of Karrot, across various contexts. We have also been interested in understanding Karrot’s impact on community-led foodsaving and sharing daily practices, as well as on community governance and organising; aspects which distinguish grassroots initiatives from more top-down anti-food waste models. We found that while Karrot facilitates certain processes, it does not fully meet the needs of the researched communities, which in turn have been configuring Karrot and have been developing unique digital ecologies, combining Karrot with off-the-shelf commercial tools. By recognising foodsaving and sharing communities as elements of a larger transformational ecosystem, we broaden our discussion to include the role of technology beyond just community-led foodsaving and sharing initiatives. Reflecting on the process of developing digital ecologies, we explore interoperability as a design element that can enhance sharing-for-community practices. Next, we propose strategies to strengthen community governance and organisation. Finally, we seed Community-Supported Software as an evolving framework that can facilitate the collaboration between grassroots place-based and software communities.

Proceedings of the CHI Conference on Human Factors in Computing Systems. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–15 doi:10.1145/3613904.3642541
[BibTeX] [Abstract] [Download PDF]Technology plays a pivotal role in driving transformation through grassroots movements, which operate on a local scale while embracing a global perspective on sustainability. Consequently, research emerged within Sustainable HCI, aiming to derive design principles that can empower these movements to scale their impact. However, a notable gap exists in contributions when addressing scalability of large free and open-source software (FOSS) projects. This paper aims to present our endeavors as action-oriented researchers with the voluntary-driven Foodsharing.de movement, focusing on a local community, the open-source developers and their connections. Within a community of 585,000 users and only a few developers that is dedicated to save and share surplus food, we explore the concepts of ‘intermediary experience’. We also introduce the notion of ‘serendipitous connections’, highlighting the unintentional yet beneficial associations that can arise from the collaboration between developers and users.

Engelbutzeder, P. (2024)Beyond sharing surplus food: on design to support grassroots initiatives in their pursuit of sustainability
Doctoral {Thesis} doi:10.25819/ubsi/10617
[BibTeX] [Abstract] [Download PDF]This dissertation examines the intersection of socio-technical design and grassroots initiatives within the domain of food saving and food sharing, rooted in the context of the Foodsharing community in Siegen, Germany. It explores how socio-technical design can support grassroots efforts in the initiation, daily operations, growth, and broader transition towards sustainable food practices. Through a practice-based and action-oriented research approach, this study delves into the nuances of community values, needs, challenges, and socio-technical practices, revealing the complexities of negotiating surplus food redistribution, community building, and the integration of prosumption practices. Key findings highlight the critical role of socio-technical design in facilitating the sharing of not just food surplus but also resources crucial for food production, thereby fostering a culture of abundance. This shift from food sharing to food resource sharing underscores a transformative ambition towards more sustainable food systems, challenging traditional economic paradigms of consumption, and promoting a holistic approach to community engagement and sustainability. By engaging with the Foodsharing community in Siegen, this dissertation uncovers the intricacies of designing socio-technical systems that accommodate the dynamics of grassroots initiatives. It presents a nuanced understanding of how digital artefacts and platforms, like Foodsharing.de and Telegram, can serve as catalysts for community building and the amplification of sustainable food practices. The study advocates for an approach that accommodates the evolving digital literacy and needs of grassroots communities to support their scaling and growth. This research contributes to the fields of Sustainable Human-Computer Interaction (SHCI), Human-Food Interaction (HFI), and action-oriented research in Human-Computer Interaction (HCI) by providing insights into the interconnectedness of socio-technical design, community building, and sustainable food practices. It emphasizes the need for HCI designs that are sensitive to the complexities of grassroots initiatives, advocating for designs that support the transition from surplus management to the realization of food abundance. In conclusion, this dissertation underlines the potential of socio-technical design in supporting societal change through grassroots initiatives, proposing a shift towards sustainability that is deeply rooted in community engagement, resource sharing practices, and the collective pursuit of abundance. It calls for further research on integrating these insights into the design of socio-technical artefacts, thereby supporting the ongoing evolution of grassroots initiatives towards sustainable food systems.

Engelbutzeder, P., Randell, D., Landwehr, M., Aal, K., Stevens, G. & Wulf, V. (2023)From Surplus and Scarcity toward Abundance: Understanding the Use of ICT in Food Resource Sharing Practices
IN ACM Transactions on Computer-Human Interaction, Vol. 30, Pages: 80:1–80:31 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 a 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]Sustainable HCI and Human-Food-Interaction research have developing interest in preventing food waste through food sharing. Sustainability requires attention to both the opportunities and challenges associated with the building of food sharing groups engaged in the redistribution of food but also in developing a wider agenda which includes, for instance, the local production of food resources. In this paper, we argue for a better understanding of the different conceptions of ‘fairness’ which inform volunteer and guest practice and in turn mediate community-building efforts. We examine the practices surrounding ‘SharingEvent’ and challenges faced to sustainability by the heterogenous, and sometimes contested, commitments of the people involved. We further consider how ICT provided opportunities for explicit examination of ideological differences concerning what ‘sharing’ might mean. Our findings show that community building is dependent on the negotiation of different values and purposes identified. We derive recommendations for action-oriented researchers ultimately concerned with systemic transformation.

, 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:10.1145/3411764.3445268
[BibTeX] [Abstract] [Download PDF]There is a developing recognition of the social and economic costs entailed in global supply chains. 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.

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.}, urldate = {2021-05-17}, booktitle = {Proceedings of the 2021 {CHI} {Conference} on {Human} {Factors} in {Computing} {Systems}}, publisher = {Association for Computing Machinery}, author = {Landwehr, Marvin and Engelbutzeder, Philip and Wulf, Volker}, month = may, year = {2021}, keywords = {Sustainable HCI, Trust, Community Supported Agriculture, Cooperative Work, Currency, Distributed Ledger Technology, Food Sovereignty, Solidarity, Technological Sovereignty}, pages = {1--13}, }

Weber, P., Engelbutzeder, P. & Ludwig, T. (2020)“Always on the Table”: Revealing Smartphone Usages in everyday Eating Out Situations
Proceedings of the 11th Nordic Conference on Human-Computer Interaction: Shaping Experiences, Shaping Society. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–13 doi:10.1145/3419249.3420150
[BibTeX] [Abstract] [Download PDF]Research on food practices and technology use is becoming more common, albeit with a constant technological determinism with respect to the support of individual practices. 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.

Engelbutzeder, P., Cerna, K., Randall, D., Lawo, D., Müller, C., Stevens, G. & Wulf, V. (2020)Investigating the use of digital artifacts in a community project of sustainable food practices: ‘My chili blossoms’
Proceedings of the 11th Nordic Conference on Human-Computer Interaction: Shaping Experiences, Shaping Society. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–4 doi:10.1145/3419249.3420089
[BibTeX] [Abstract] [Download PDF]Research on food practices has become more common among scholars of HCI in recent years. Human-Food-Interaction (HFI) looks into the interplay of humans, food and technology. HFI, even so, has paid relatively little attention to the more collective elements of food practice, including social bonding [1]. The modest project we describe below aimed to say something about the use of digital artifacts to support community engagement for sustainable food practices. We participated, as action researchers (see [2]) in a grassroots movement that instigated a project around learning about food growing, using digital means to bring interested people together during times of physical distancing: In the project Vegetables seek a home, people from various backgrounds ‘adopted’ a chili-plant, they are invited to share what they like in a Telegram-Group, and to get learning-modules via a mailing-list. 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.

Lawo, D., Esau, M., Engelbutzeder, P. & Stevens, G. (2020)Going Vegan: The Role(s) of ICT in Vegan Practice Transformation
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.

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.
