As of June 2008, Nintendo has sold nearly 30 million Wii game consoles. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. It contains a 1024x768 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 expandsion port for even more capability. These projects are an effort to explore and demonstrate applications that the millions of Wii Remotes in world readily support.
