    A head-in-hand metaphor for user-centric direct camera control in virtual reality
    (Mensch und Computer 2020 - Tagungsband, 2020) Günther, Tobias; Querner, Erich; Groh, Rainer
    The explorative examination of constructed 3D models in immersive environments requires suitable user-centric interaction methods. Especially novel concepts for virtual camera control can offer advantages, e.g. for the analysis of model details. We extend the known concept of the camera-in-hand metaphor and implement a multidimensional viewport control technique that can be used with common head-mounted displays and VR-controllers. With our head-in-hand view the user is able to control the virtual camera directly by hand without losing the flexibility of head movements. To ensure convenient operation, the method restricts special rotation parameters and smoothes jerky gestures of the user hand. In addition, we discuss implications and improvement potential of the proposed concept as well as adverse effects on the user, such as motion sickness.

    A user-centric approach to IT-security risk analysis for an identity management solution
    (Open Identity Summit 2022, 2022) Fähnrich, Nicolas; Winterstetter, Matthias; Kubach, Michael
    In order to build identity management (IdM) solutions that are secure in the practical application context, a holistic approach their IT-security risk analysis is required. This complements the indispensable technical, and crypto-focused analysis of risks and vulnerabilities with an approach that puts another important vector for security in the center: the users and their usage of the technology over the whole lifecycle. In our short paper we focus exclusively on the user-centric approach and present an IT-security risk analysis that is structured around the IdM lifecycle.
