In this talk I will give an overview of systems that combine interactive surfaces with personal mobile devices. Mobile devices have been used for some time for individual interactions with large public displays. Now, mobile devices, and mobile phones in particular, are increasingly used for collaborative interactions with interactive tabletops. Personal devices have benefits beyond providing a private display and private data storage. In multi-user situations, personal input devices on interactive surfaces solve the common problem of assigning user identities to individual input actions. I will present a number of important projects and highlight novel interaction possibilities. These include spatial interactions that use device positions and orientations on the tabletop, device-bound interactions that take advantage of (multi-)touch screens, and gestural interactions using integrated accelerometers to detect device tilts and fast movements.
Dr. Michael Rohs is a senior research scientist with Deutsche Telekom Laboratories at TU Berlin. His primary research interests are in pervasive computing and mobile interaction. This includes the integration of physical and virtual aspects of the user's environment, sensor-based mobile interaction, and handheld augmented reality. His research currently focuses on small-display interaction, in particular navigation and visualization techniques for spatially aware displays. An example is using camera phones as magic lenses for large-scale paper maps in order to overlay personalized, up-to-date information. As part of his doctoral dissertation he developed camera-based interaction techniques for mobile devices, like optical flow control for large public displays and a marker recognition system for camera phones that uses device orientation as an input parameter. In the winter semester 2007/08 he had a guest professorship (Vertretungsprofessur) for User Interface Engineering at the Bonn-Aachen International Center for Information Technology (b-it). In 2005 he obtained a Ph.D. in Computer Science from ETH Zurich, Switzerland.
