Replicating Interactive Surfaces Using Distortion Techniques

Abstract

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.
