    Take Your Security and Privacy Into Your Own Hands! Why Security and Privacy Assistants Should be Tangible
    (Mensch und Computer 2021 - Workshopband, 2021) Delgado Rodriguez, Sarah; Prange, Sarah; Alt, Florian
    In the era of ubiquitous computing, users security and privacy is at risk at almost all times. Security and privacy assistants support their users in becoming aware of these risks and taking the appropriate measures to protect their data. However, they often suffer from being too complex, not intuitive and non-engaging. Hence, in order to truly enable less tech-savvy or inexperienced persons to use security and privacy assistants, we argue that such mechanisms must become tangible in the future.

    Towards a Universal Human-Computer Interaction Model for Multimodal Interactions
    (Mensch und Computer 2021 - Tagungsband, 2021) Faltaous, Sarah; Gruenefeld, Uwe; Schneegass, Stefan
    Models in HCI describe and provide insights into how humans use interactive technology. They are used by engineers, designers, and developers to understand and formalize the interaction process. At the same time, novel interaction paradigms arise constantly introducing new ways of how interactive technology can support humans. In this work, we look into how these paradigms can be described using the classical HCI model introduced by Schomaker in 1995. We extend this model by presenting new relations that would provide a better understanding of them. For this, we revisit the existing interaction paradigms and try to describe their interaction using this model. The goal of this work is to highlight the need to adapt the models to newinteraction paradigms and spark discussion in the HCI community on this topic.

    User Experience of 3D Map Navigation – Bare-Hand Interaction or Touchable Device?
    (Mensch und Computer 2016 - Tagungsband, 2016) Tscharn, Robert; Schaper, Philipp; Sauerstein, Jan; Steinke, Sarah; Stiersdorfer, Sebastian; Scheller, Carsten; Huynh, Huy Tan
    New tracking technologies allow users to interact with digital systems in a more naturalistic way, while touchable interfaces represent a more precise but also less direct interaction. In this study, example devices for each of these interaction styles were compared in terms of their suitability for free navigation in a 3D Map. Efficiency, subjective attractiveness ratings and joy-of-use based on displayed emotions in differently complex tasks were measured. We focused on users without prior experience with both respective devices, allowing insights on first impressions and unbiased interaction. Our results showed higher joy-of-use and better efficiency in an easy navigation task for bare-hand interaction. Interestingly efficiency also improved for more complex tasks, after participants first worked with a touchable interface.
