TOUCH SURFACE AND SYSTEM AND METHOD OF DETECTING TOUCH INPUT

摘要

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.
