RoomAlive, project mapping and augmented reality using a kinect
I realy love this MSFT project:
The RoomAlive Toolkit enables developers to network one or more Kinect sensors to one or more projectors and, by so doing, to project interactive experiences across the surfaces of an entire room. The toolkit provides everything needed to do interactive projection mapping, which enables an entirely new level of engagement, in which interactive content can come to virtual life on the walls, the floor, and the furniture. Imagine turning a living room into a holodeck or a factory floor—the RoomAlive toolkit makes such scenarios possible.
Watch this video. Now if only MSFT (or someone else) would release this for the OSX...
