However, there's still no UK release date for the add-on that will enable Xbox users to play games by moving parts of their body, rather than a handheld controller. The technology can also identify different people's faces and recognise different voices.
Kinect will be made available on November 4 in the US, where it will cost $150 (about £98). It will also come with a copy of Kinect Adventures - a game collection compatible with the motion-sensing camera that includes a white water rapids race and a ball batting game.
Microsoft also said it will offer a much smaller version of the Xbox 360 that comes with 4GB flash memory rather than an integrated hard drive. Priced at £149.99, it will be available from August 20 and features a matt black finish and built-in Wi-fi adaptor.
The company is planning to bundle the Kinect camera with the nex Xbox and Kinect Adventures for £249.99. However, Microsoft didn't offer a release date for the bundle.
"Kinect for Xbox 360 offers fantastic new ways to be entertained for the whole family," said Chris Lewis, vice president, Interactive Entertainment Business at Microsoft Europe.
"With full body, voice and multiplayer play straight out of the box, Kinect is a unique way for everyone to enjoy controller-free fun and entertainment."
