Abstract
An electro-optic video display apparatus consists of a plurality of optical fibers or light guides which convey a projected image from one or more projection surfaces to a larger display surface. The second surface is fashioned with additional optical circuits that transfer light and/or information incident upon the second surface to one or more third surfaces, for the purpose of detecting the proximity and/or motion of persons or objects near to the second surface.
