A system for providing a dynamic audio-visual environment using an
eSurface situated in a room environment; a projector situated for
projecting images onto the eSurface; a camera situated to picture the
room environment; a central processor coupled to the eSurface, the
projector and the camera. The processor receives pictures from the camera
for detecting the location of the eSurface; and controls the projector to
aim its projection beam onto the eSurface. The eSurface is a sheet-like
surface having the property of accepting optically projected image when
powered, and retaining the projected image after the power is turned off.
