Remember IllumiRoom? It's the Microsoft Research project that pairs an Xbox Kinect with a projector to extend your TV onto a wall, resulting in an immersive (and hallucinogenic) experience. Redmond has just revealed that IllumiRoom 2.0 is now called RoomAlive and is a huge leap over what it was last year. The new system projects content throughout a room that you can interact with (or shoot), as shown in the insane video below. Instead of a single Kinect and projector, it uses multiple "procams" consisting of off-the-shelf projectors, Kinects and a control device. Microsoft claims that it's completely auto-calibrating and self-locating, enabling it to calculate the entire 3D geometry of your room in minutes.
