    Vita

    Philip Engelbutzeder studierte an der Universität Siegen und hat dort ein Diplom in Deutschem und Europäischem Wirtschaftsrecht abgeschlossen. In seiner Abschlussarbeit beschäftigete er sich mit der Bedeutung subjektiver Wirklichkeit für das Management von Beziehungen. In seiner Promotion verbrachte Philip vier Jahre ohne eigene Wohnung, aber dafür mit (inter-)nationalen Bewegungen eines sozio-ökonomischen Wandels.

    Mittlerweile befindet sich Philip wieder in der Stadt Siegen und forscht in den Bereichen Sozio-Informatik und Plurale Ökonomie. Seine Forschung konzentriert sich auf nachhaltige Lebensmittelpraktiken, mit dem Schwerpunkt auf unseren alltäglichen Umgang des Retters und Teilens von Lebensmitteln und der unterstützenden Rolle von Informations- und Kommunikationstechnologie. Philip Engelbutzeder ist Aktionsforscher, der viele Jahre mit Graswurzelbewegungen verbracht hat, sowohl mit denen, die Open-Source-Anwendungen entwickeln, als auch mit lokalen Gemeinschaften, die diese nutzen. In Siegen beteiligt sich Philip Engelbutzeder mit den Initiativen ‚Siegen isst bunt’ und ‚Foodsharing Siegen‘ sowie dem Verein ‚Lebensmittel-Teilen e.V.‘ beispielweise am Ausbau und der Pflege von Gemeinschaftsgärten, Saatgutbörsen oder der Lebensmittel-Fairteilung am Heimatverein Achenbach.

    • Lawo, D., Neifer, T., Esau, M., Engelbutzeder, P. & Stevens, G. (2021)Scan&Go: Understanding Adoption and Design of Smartphone-based Self-checkout

      , 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.

      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.

    • 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

      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.

    • 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’.

    • 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

      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., 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.

      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.
