An Optical Laser-based User Interaction System for CAVE-type Virtual Reality Environments

  • This contribution describes an optical laser-based user interaction system designed for virtual reality (VR) environments. The project's objective is to realize a 6-DoF user input device for interaction with VR applications running in CAVE-type visualization environments with flat projections walls. In case of a back-projection VR system, in contrast to optical tracking systems, no camera has to be placed within the visualization environment. Instead, cameras observe patterns of laser beam projections from behind the screens. These patterns are emitted by a hand-held input device. The system is robust with respect to partial occlusion of the laser pattern. An inertial measurement unit is integrated into the device in order to improve robustness and precision.
