Wii Hack Creates 3D Virtual-Reality Head Tracking System

Back in the olden days, 3D head-tracking required a massive helmet that made you look like a classic Cylon warrior with a severe case of water-retention.  Now, Carnegie Mellon University's Johnny Chung Lee can show you how to hack up your own system using a Nintendo Wii.https://www.youtube.com/watch?v=Jd3-eiid-Uw

"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" Johnny Chung Lee
