    Biomaterials for Prototyping in HCI
    (Mensch und Computer 2024 - Workshopband, 2024) Nicolae, Madalina; Roussel, Vivien; Koelle, Marion; Lefez, Claire; Roudaut, Anne; Nittala, Aditya Shekhar; Huron, Samuel; Teyssier, Marc; Steimle, Jürgen
    While prototyping is a widespread practice among researchers, creating sustainable, functional devices remains challenging due to the limited range of available tools and materials. We present several approaches to sustainable prototyping of functional devices. Our methods range from using bio-based and bio-degradable materials as sustainable alternatives to biologically growing electronic substrates. These methods enable a new class of interactive devices that integrate electronic components with sustainable materials. Our research on Interactive Bioplastics [1] introduces a DIY approach for producing conductive bioplastics that are compatible with digital fabrication techniques. Furthermore, [2] introduces an integrated fabrication framework for sustainable soft shape-changing interfaces made of bioplastics. Finally, our work on Biohybrid Devices [3] showcases how the biological growth of living bio-materials--such as Bacterial Cellulose--can be used as assembling and embedding process for electronics. In addition to presenting various artifacts, we highlight the processes introduced by our fabrication frameworks [1-3] and engage the audience in discussions about the life-cycle phases of producing artifacts, promoting a critical reflection of sustainable practices in prototyping.

    Interaction in the Public: Aesthetics, Social Acceptability, and Social Context
    (Mensch und Computer 2021 - Workshopband, 2021) Uhde, Alarith; Tretter, Stefan; von Terzi, Pia; Koelle, Marion; Diefenbach, Sarah; Hassenzahl, Marc
    Even in moments considered private, others often witness how we interact with technology. A typical example is smartphone use at home, in the presence of family members. This of course becomes even more likely in public - on streets, in libraries, or in the supermarket, places full of other people. The social context brings challenges and opportunities. When designing interaction, we often primarily focus on what users experience, like, and accept. Less do we explicitly consider what present others may think or feel about this interaction, and how it relates to their own current activities. This requires a deeper understanding of social context and frugal but sufficiently rich context descriptions. In turn, considering present others allows us to learn about what types of interaction are acceptable or even aesthetic in what types of context. In this workshop, we collaboratively explored the largely untouched questions of positive interaction from the perspective of others, and worked out ways in which these could improve the design process.

    Towards Respectful Smart Glasses through Conversation Detection
    (Mensch und Computer 2018 - Tagungsband, 2018) Meirose, Franziska; Schultze, Sven; Kuehlewind, Sebastian; Koelle, Marion; Abdenebaoui, Larbi; Boll, Susanne
    Talking to each other is personal, maybe even intimate. Thus, privacy expectations are particularly high during interpersonal conversations, and image or audio recordings are problematic in these contexts. In consequence, smart glasses and other body-worn devices with “always-on” cameras are not well accepted during interpersonal conversations. Proposing a simple-to-implement computer vision procedure, we work towards a solution to this issue. Using imagery from a head-worn camera we detect face-to-face conversations in real-time, as well as distinguish between intimate, personal and social conversations based on intrinsic camera parameters. Starting from a fictive scenario, we illustrate how this knowledge can be used for interaction designs that increase both, the users’ as well as their bystanders’ privacy, e.g., by muting audio or disabling the camera. Finally, we suggest directions for future work.
