CA 2182238

A input device comprises a two-dimensional surface capable of presenting predefined regions to a user, a video camera directed at said two-dimensional surface for creating real-time images thereof, a device for analyzing he real-time images to identify which pre-defined region is being pointed to by a user, and a device for outputting a signal dependent on the identified region pointed to by the user. The input device can act as an alternative pointing device for a computer, for example.

L'invention est un système de saisie comportant une surface bidimensionnelle pouvant présenter des régions prédéfinies à un utilisateur, une caméra vidéo dirigée sur ladite surface bidimensionnelle et servant à créer des images en temps réel de cette surface, un dispositif servant à analyser les images captées en temps réel pour reconnaître la région prédéfinie désignée par l'utilisateur et un dispositif générateur de signaux variables selon ladite région désignée. Le système de saisie de l'invention peut servir de dispositif de pointage auxiliaire pour un ordinateur, par exemple.
