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.

La présente invention concerne un système d'affichage comprenant un panneau optique à guide d'onde qui présente une face d'entrée et une face de sortie opposée. Un projecteur et un dispositif d'imagerie coopèrent avec le panneau afin d'y projeter une image. Un détecteur optique se trouve à proximité du panneau et permet de détecter un emplacement sur la face de sortie d'un point de lumière entrant. La lumière entrant est canalisée jusqu'au détecteur qui peut être de taille réduite.
