Microsoft is looking to extend its surface-computing work into the spatial-computing arena with a new research project known as LightSpace. "LightSpace combines elements of surface computing and augmented reality research to create a highly interactive space where any surface, and even the space between surfaces, is fully interactive. Our concept transforms the ideas of surface computing into the new realm of spatial computing. The cameras make it appear that users are carrying projected objects in their hands and then "dropping" them onto walls, where they can be manipulated using multitouch gestures similar to those used with the Microsoft Surface tabletop."
"Instrumented with multiple depth cameras and projectors, LightSpace is a small room installation designed to explore a variety of interactions and computational strategies related to interactive displays and the space that they inhabit. LightSpace cameras and projectors are calibrated to 3D real world coordinates, allowing for projection of graphics correctly onto any surface visible by both camera and projector. Selective projection of the depth camera data enables emulation of interactive displays on un-instrumented surfaces (such as a standard table or office desk), as well as facilitates mid-air interactions between and around these displays."
