Abstract
An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes at least one emitter and detectors. Each emitter produces optical beams which are received by the detectors. Touch events disturb the optical beams. Touch event templates are used to determine the actual touch events based on which optical beams have been disturbed.
