The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. The optical beams preferably are multiplexed in a manner so that many optical beams can be received by a detector simultaneously. Touch events disturb the optical beams. To determine whether a candidate touch point is an actual touch event, multiple beams that would be affected are considered together."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting multitouch events in an optical touch-sensitive device by combining beam information","description":"An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events.
