    Digital Behavioral Lab

     

    „Digitale Möglichkeiten bieten große Vorteile und Erleichterungen bei den Fragen der täglichen Lebensführung und des Konsums. Gleichzeitig bringt die digitale Welt aber auch Risiken mit sich, die im Gegensatz zum unmittelbar erfahrbaren Nutzen eher langfristig, häufig verborgen oder zumindest schlecht einschätzbar sind.“ – Reisch et al. 2016

     

    Digital Behavioral Lab (DBL)

    Das DBL ist eine interdisziplinäre Arbeitsgruppe an der Universität Siegen zur Untersuchung des menschlichen Verhaltens mit dem Ziel digitalisierte Konsumpraktiken von Verbrauchern zu unterstützen und zu schützen.Das DBL wird von Prof. Dr. Gunnar Stevens und Prof. Dr. Volker Wulf geleitet. Bei der Durchführung empirischer Studien arbeitet es eng mit den PRAXLABS zusammen und kann dadurch für seine Studien auf eine breites Panel von interessierten Haushalten, sowie Unternehmen und Verbänden zurückgreifen. Durch seinen interdisziplinären Ansatz kann das DBL in seinen Studien darüber hinaus auf eine breit gefächerte Expertise zurückgreifen. Im wesentlichen angesiedelt im Bereich des User Experience Design und der Usability, insbesondere Usable Privacy, können je nach Kontext entsprechende Experten der Wirtschaftsinformatik, des Rechts und der Medienwissenschaften herangezogen werden. Die wirtschaftswissenschaftliche Kompetenz wird darüber hinaus durch eine enge Kooperation mit der Hochschule Bonn-Rhein-Sieg sicher gestellt.

    Forschungsfelder

    Die Forschungsfelder des DBL orientieren sich an den Konsumbereichen „Wohnen“, „Gesundheit / Ernährung“, und „Mobilität“. Für diese Felder wurden in den letzten Forschungsprojekten und Studien durchgeführt. Hierbei wird die Digitalisierung als Querschnittsthema betrachtet, bei der immer zugleich Risiken, als auch Nutzen aus der Verbraucherperspektive betrachet und entsprechend gestaltet wird. Ziel dabei ist es im Sinne der mehrseitigen Sicherheit einen, für alle Parteien tragfähigen Kompromiss zu finden, das heißt Mehrtwerte aus jeweiliger Stakeholder-Sicht zu wahren, Interessen auszutarieren und zugleich die digitale Souvernität von Verbrauchern zu unterstützen. Die wissenschaftliche Grundlage unserer Forschung bilden praxistheoretische Ansätze aus der neueren Privacy- und Verbraucherforschung.

      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.

    • Schwartz, T., Stevens, G., Jakobi, T., Denef, S., Ramirez, L., Wulf, V. & Randall, D. (2014)What People Do with Consumption Feedback: A Long-Term Living Lab Study of a Home Energy Management System

      [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.

      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.
