Microsoft introduces at the E3 2009 its Project Natal motion control system for XBox 360. The Project Natal is a revolutionary new way to play that does not require a controller. With the Project Natal, You, yourself, is the controller.
The Projector Natal system combines an RGB camera, depth sensor, multi-array microphone and custom processor in one device, that tracks your full body movement in 3D. The system can understand your movement, and what your said. It can even respond to a shift of emotion in your voice.
