OVERVIEW
Kinect (originally known by the code name Project Natal), is a "controller-free gaming and entertainment experience" by Microsoft for the Xbox 360 video game platform. Based around a webcam-style add-on peripheral for the Xbox 360 console, it enables users to control and interact with the Xbox 360 without the need to touch a game controller, through a natural user interface using gestures and spoken commands. The project is aimed at broadening the Xbox 360's audience beyond its typical gamer base. Kinect competes with the Wii Remote Plus and PlayStation Move and PlayStation Eye motion control systems for
the Wii and PlayStation 3 home consoles, respectively. Kinect was launched in North America on November 4, 2010, in Europe on November 10, 2010, in Australia, New Zealand and Singapore on November 18, 2010 and in Japan on November 20, 2010. Purchase options for the sensor peripheral include a bundle with the game Kinect Adventures and console bundles with either a 4 GB or 250 GB Xbox 360 console and Kinect Adventures. Kinect holds the Guinness World Record of being the "fastest selling consumer electronics device". It sold an average of 133,333 units per day with a total of 8 million units in its first 60 days. 10 million units of the Kinect sensor have been shipped as of March 9, 2011. Microsoft has announced the release of a non-commercial Kinect software development kit for Windows in spring 2011, with a commercial version following at a later date.

TECHNOLOGIES
Kinect is based on software technology developed internally by Rarre, a subsidiary of Microsoft Game Studios owned by Microsoft, and on range camera technology by Israeli developer PrimeSense, which interprets 3D scene information from a continuouslyprojected irnfrared structured light. This 3D scanner system called Light Coding employs a variant of image-based 3D reconstruction. The Kinect sensor is a horizontal bar connected to a
