摘要:
An apparatus, method and system are disclosed for touch and gesture detection. A light source array comprises a plurality of light sources. Each light source of the light source array transmits a light beam across a face of a display in response to being activated. A light sensor array comprises a plurality of light sensors. Each light sensor of the light sensor array detects an intensity of each light beam transmitted across the face of the display in response to being activated. A controller concurrently activates each light source of the light source array with each light sensor of the light sensor array as a source/sensor pair during a detection cycle while other light sources of the light source array and other light sensors of the light sensor array are inactive. The controller further determines a location of a pointer relative to the display from a pattern of light beam intensities for each source/sensor pair.
