    Enhancing Interactive Tabletop Workspaces with Tangible Contexts
    (Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Ott, Markus; Luderschmidt, Johannes; Dörner, Ralf; Kim, HyungSeok; Kim, Jee-In
    In this paper, we introduce our concept of tangible contexts in the field of seamless interaction in shared workspaces between mobile devices and tabletop systems. We model the context as a relationship between a user, the user s mobile device and objects on the surface of an interactive tabletop system. The tabletop represents the public part of the context and the mobile device embodies the private part of the context in a tangible form. The mobile device s touchscreen provides an additional workspace, its gyroscopic sensors allow for detection of the device s orientation in the air and it can be used as multi-purpose tangible object on the tabletop s surface. Additionally, an interaction performed with a mobile device can be technically and conceptually linked to its owner. In particular, users can automatically authenticate interactions by using their own device. Therefore, by employing tangible contexts it is possible complementing public interaction on the tabletop with private interaction on the mobile device and providing an ownership metaphor of UI elements on an interactive surface.

    Replicating Interactive Surfaces Using Distortion Techniques
    (Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Lee, Jooyoung; Dörner, Ralf; Luderschmidt, Johannes; Kim, HyungSeok; Kim, Jee-In
    In this paper we present a distortion technique that provides a focus & context view of an interactive surface s screen on a mobile device. Simply showing a reduced version of the surface s screen on the mobile device would not have been sufficient as UI elements could be too small to be manipulated. Users modify the region of interest (ROI) of the focus & context distortion via gestural input on their device. We employ this technique in our system that transmits interaction on the mobile device via TUIO to the interactive surface. Thus, users may interact remotely with any TUIO-based application on the surface without additional implementation effort while real-time constraints are still met.
