Virtual Rear Projection uses multiple front projectors to present a
robust image in the face of occlusions. By detecting when an occluder
blocks light from one of the projectors, we are able to turn off
pixels that are occluded, removing the "blinding light" from users.
At the same time, we increase the illumination from non-occluded
projectors to eliminate the shadows, presenting a display that rivals
the quality of a rear-projected surface.
We are currently evaluating virtual rear projection with user
studies.
Virtual Rear Projection technology is being used to provide computer
output capability for the BigBoard.
