Head Tracking for Desktop VR Displays using the WiiRemote
Johnny Lee a PhD. Graduate student at Carnegie Mellon University in the Human-Computer Interaction Institute:
Using the infrared camera in the Wii remote and a head mounted sensor bar (two IR LEDs), you can accurately track the location of your head and render view dependent images on the screen. This effectively transforms your display into a portal to a virtual environment. The display properly reacts to head and body movement as if it were a real window creating a realistic illusion of depth and space.
