摘要: A system and method for touch detection and a touch-responsive surface are provided. According to one embodiment, a “virtual” touch-sensitive surface in is provided in that a plurality of transmitter-sensor devices receive and calculate a touch by detecting position and movement on a touch surface. The touch surface includes a planar surface; a first transmitter-sensor device located at a first position proximate to the planar surface and a second transmitter-sensor device located at a second position proximate to the planar surface, wherein each of the transmitter-sensors 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 and the second transmitter-sensor device, 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.
