Microsoft Reveals Prototype Wrist Controller

Xbox's existing Kinect motion capture control method.

Speaking to New Scientist, project leader David Kim claimed that the finished product would be much smaller and neater than the prototype shown here.

He said: "We had to use technologies that are small and use less power. It shouldn't interfere with daily activity, and we wanted to enable continuous interaction.

The prototype was created entirely from existing technology and is reportedly composed of an infra-red camera, infra-red laser line generator, an infra-red diffuse illuminator and an inertial measurement unit.

The IR camera captures three images in rapid succession, then combines them to represent the hand's position in real time.

Despite the new technology being unveiled, the next generation Xbox is still expected to ship with an updated version of Kinect.
