CCD Camera Based Optical Tracking for Human Computer Interaction

We are investigating the application of CCD camera based optical beacon tracking systems in d interactive environments An optical tracking system has been developed which serves as a testbed for tracking algorithms and accuracy investigations The d interactive environment fea tures tracking of the observer s viewpoints stereo scopic visualization and direct d pointing The focus is set on high accuracy of both tracking and stereo scopic visualization Algorithms which can track optical beacons with sub pixel resolution at low noise help to reduce hardware expenditure in terms of camera resolution and computing power Theoretical considerations about resolution are made and practical experience is presented Furthermore user studies are performed to test the created interface environment with regard to immersive interfaces and direct interaction in space
