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 a video image thereon. An optical detector
bridges at least a portion of the waveguides for detecting a location on
the outlet face within a target zone of an inbound light spot. A
controller is operatively coupled to the imaging device and detector for
displaying a cursor on the outlet face corresponding with the detected
location of the spot within the target zone.
