Head Tracking with the Wii
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. This is an amazing way of creating a more personal and realistic gaming experience. This could be transfered into 3D modeled worlds and such like as the viewer or creator could step inside the creation and react view the environment as it has been made.
