Abstract
An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events disturb the optical beams. Detection schemes define the operation of the touch capability. Different detection schemes consume different amounts of power and may be used in combination to reduce overall power consumption.
