Details of Kinect's working exposed by patent

Microsoft's patent application for its Kinect motion controller has recently gone public, giving everyone an inside look at how the technology works. The system uses software called PrimeSense to detect the user's movements thanks to a webcam. The camera detects human targets and compares them to a stored pattern of a human body model.

Each target that matches the human body model can be scanned to create a skeletal model associated with it. It then renders an avatar associated with the skeletal model and determines which controls to perform based on the movement of those parts of the body. The system can identify or cross-match at least 25 points on the user's body thanks to its skeleton model.

Kinect was the result of Microsoft acquiring 3DV technology for camera-based recognition but is believed to use newer techniques optimized for the nature of games, such as determining whether someone is sitting or standing. It arrives November 4 in a $150 stand-alone kit or as part of a $299 Xbox 360 Arcade bundle. [via GoRumors]

    Can you say Sony EyeToy?

    Does MicroSoft *ever* come up with an original idea?
    Just google for "Sony EyeToy" -- there's a great wikipedia page on the history.

    Can you Say 3D

    A) The Eyetoy can not detect movement in 3 dimensional space. Kinect has an Infar Red Depth sensor that interprets distance from the camera.
    B) The Eyetoy can not determine a 3 Dimensional skeletal model. It can only detect edges of movement.
    C) If the Eyetoy did everything you claim it can why didn't Sony patent it???
    D) You own a PS3
