Wireless interaction in cost-effective display environments

We present a cost effective display environment (VE) with wireless interaction devices. The system was setup and tested in the laboratory. A user feedback was obtained during use of the system at various exhibitions. The application is wireless navigation through several virtual worlds. For this task we investigate the use of wireless input systems for immersive interaction in a virtual environment displayed on a 2m x 1.5m stereoscopic projection system. For head tracking, a cluster of commercially available optical trackers with a single passive reflective target is used. For manual interaction, wireless button devices with inertial sensors for acceleration and spin have been built. The application of these devices and the combination of input channels in different interactions is presented. The image generation and simulation system is based on standard PC hardware running the operating system Linux.
