Microsoft may not have an official presence at CES 2013, but the company just showed some new Kinect-powered technology that expands video game graphics beyond the boundaries of the television. Called IllumiRoom, the proof-of-concept from Microsoft Research combines Kinect and a video projector to amazing effect.

A demo video of IllumiRoom shows how a Kinect for Windows camera scans the geometry of a room and tailors visuals projected outside the television to complement what's happening on the screen. The system, Microsoft Research says, "can change the appearance of the room, induce apparent motion, extend the field of view and enable entirely new game experiences."

Microsoft says the effects shown in the IllumiRoom demo are rendered in real time and captured live.

Additional IllumiRoom details are promised at CHI 2013, which runs April 27 to May 2 in Paris.
