Andy Wilson, senior researcher and Hrvoje Benko, researcher, both from Microsoft Research explain their LightSpace research project.
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.
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. For example, after performing multi-touch interactions on a virtual object on the tabletop, the user may transfer the object to another display by simultaneously touching the object and the destination display. Or the user may “pick up” the object by sweeping it into their hand, see it sitting in their hand as they walk over to an interactive wall display, and “drop” the object onto the wall by touching it with their other hand.
