Nintendo has sold over 13 million Wii since September 2007. The Nintendo Wii is one of the most sophisticate consoles on the market as it contains a 1024×768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz.

This significantly out performs any PC “webcam” available today. It also contains a +/-3g 8-bit 3-axis accelerometer also operating at 100Hz and an expansion port for even more capability. To demonstrate its capability Johnny Chung Lee, a PHD graduate student at Carnegie Mellon University is showing us how to effectively use the infrared remote and a head mounted sensor bar to accurately track the location of your head and render view dependent images on the screen.

In another video Lee is demonstrating another use for the Wii infrared remote. This time using an LED array and some reflective tape, he can use it to track his fingers in 2D space. This method can be use to interact with the computer by simply waving the fingers at the monitor.
