Head tracking for Desktop Virtual Reality Displays using the Wii Remote
http://www.youtube.com/watch?v=Jd3-eiid-Uw
Johnny Lee demonstrates how to modify the hardware of the Nintendo Wii to allow it to track the head of the user in relation to the display. Normally, the infrared emitter is placed in a static spot in front of the television, but by placing the wii remote in that spot, the emitter can be attached to the head of a person for accurate head tracking.
Johnny demonstrates how the illusion is created. The background is essentially separated, moved back, and then shifted away from the direction of the users head. This renders the frame of the display as the border of a "window" into a virtual world.
This work is similar to my idea of changing the camera view in a display based on tracking the head. Here, however, the technology used is infrared sensors and emitters. I am using video capture which would be different. I would have to find a method of finding the users face in the camera's field of view.

The Xbox 360 Kinect is an add-on peripheral for the xbox 360 video game console. The peripheral has a regular 640 by 480 VGA camera, an infrared camera, a infrared dot matrix emitter, and a microphone array. The peripheral uses the infrared camera and the infrared emitter to capture 3 dimensional depth. The 3d data is then processed by the xbox 360 to track a persons entire body.
This piece of hardware represents a good advance in the direction of human interface with virtual worlds. The Kinect is touted as being easy too get into thanks to its "controller-less" system. Their catch phrase is "you are the controller". This peripheral is a good example at trying to make an interface more intuitive and easier to learn. I likewise wish to accomplish that with my project.
