Title (EN) TOUCH SURFACE AND SYSTEM AND METHOD OF DETECTING TOUCH INPUT
(FR) SURFACE TACTILE ET SYSTÈME ET PROCÉDÉ DE DÉTECTION DE SAISIE TACTILE
Abstract:
(EN) A system and method for touch detection and a touch-responsive surface are provided, a "virtual" touch-sensitive surface is provided in that a plurality of transmitter-sensor devices (102,104) receive and calculate a touch by detecting position and movement on a touch surface (100). The touch surface (100) includes a planar surface, a first transmitter-sensor device (102) located at a first position proximate to the planar surface and a second transmitter-sensor device (104) located at a second position proximate to the planar surface, wherein each of the transmitter-sensors (102,104) includes a light beam emitter and a scanning micromirror to reflect the light beam across the planar surface. A processing unit is in operable communication with the first transmitter-sensor device (102) and the second transmitter-sensor device (104), and the processing unit is configured to calculate the position of a touch on the planar surface based on one or more times of refection of the light beams.
(FR) L'invention concerne un système et un procédé pour la détection de toucher et une surface tactile, une surface tactile « virtuelle » étant fournie. Une pluralité de dispositifs émetteurs-capteurs (102,104) reçoivent et calculent un toucher en détectant la position et le mouvement sur une surface tactile (100). La surface tactile (100) comprend une surface plane, un premier dispositif émetteur-capteur (102) situé dans une première position proche de la surface plane et un second dispositif émetteur-capteur (104) situé dans une seconde position proche de la surface plane, chacun des émetteurs-capteurs (102, 104) comprenant un émetteur de faisceau lumineux et un micromiroir de balayage pour refléter le faisceau lumineux sur la surface plane. Une unité de traitement est en communication fonctionnelle avec le premier dispositif émetteur-capteur (102) et le second dispositif émetteur-capteur (104), et l'unité de traitement est configurée pour calculer la position d'un toucher sur la surface plane sur la base d'une ou de plusieurs réflexions des faisceaux lumineux.
