Dubbed Kinect for Xbox 360, the controller-free game device is set to go on sale in November. The technology behind Natal is fairly simple, a TV-mounted camera/microphone bar to sense motion, sound, and movement. What's new and ground breaking is the tracking of 3D movement as well as 2D movement. The system is also able to scan users faces and sign them into Xbox live, as well as react to vocal tone and pitch, and process this data in real-time.
