Google terms to search for "augmented desk" "InteractiveDESK" This idea is introduced roughly every 4 years at least since the first time I saw it in the early 90s. There has been some limited commercial success. The local mall had a 100 sq ft model for kids to play with in one of the walkways. Balls bounce around and react when people walk into them. Its more or less a kinect with substantial changes in scale and optical path.
