Abstract
A display system includes a waveguide optical panel having an inlet face and an opposite outlet face. A projector and imaging device cooperate with the panel for projecting an image thereon. An optical detector is located near the panel for detecting a location on the outlet face of an inbound light spot. The inbound light is channeled to the detector which may be of a reduced size.
