Microsoft said on Monday that Kinect (Project Natal) will be available on November 4 in the U.S.

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.

Microsoft demonstrated their Kinect system by waving to sign into the console and controlling different console elements by saying "Xbox" followed by music or pause to pause live video. Zune for Xbox was also demonstrated with some Justin Bieber music where the user was able to play and pause the music. Video Kinect was also announced. The service lets users communicate via the sensor for video or audio chat. The Video Kinect service works across Xbox Live and Windows Live Messenger and allows users to watch movies together and chat.
