Abstract
A touch-sensitive device includes multiple emitters and detectors and at least one acoustic sensor. Each emitter produces optical beams which are received by the detectors. Touch objects (e.g., fingers, pens, styluses) disrupt some of the optical beams and generate vibrations that are detected by the acoustic sensor. The touch-sensitive device determines information about touch events based on beam data derived from the output of the detectors and acoustic data derived from the output of the acoustic sensor.
