Kinect is based on software technology developed internally by Rare, a subsidiary of Microsoft Game Studios owned by Microsoft and range camera technology by Israeli developer PrimeSense, which interprets 3D scene information from a continuously-projected infrared structured light.
The Kinect sensor is a horizontal bar connected to a small base with a motorized pivot, and is designed to be positioned lengthwise above or below the video display. The device features an "RGB camera, depth sensor and multi-array microphone running proprietary software", which provides full-body 3D motion capture, facial recognition and voice recognition capabilities. Voice recognition capabilities will be available in Japan, the United Kingdom, Canada and the United States at launch, but have been postponed until spring 2011 in mainland Europe. The Kinect sensor's microphone array enables the Xbox 360 to conduct acoustic source localization and ambient noise suppression, allowing for things such as headset-free party chat over Xbox Live.
