Abstract
A touch sensitive device includes a touch surface and emitters and detectors. The emitters produce optical beams that propagate across the touch surface and are received by the detectors. Touch events from a touch object disturb the beams propagating toward the detectors. Beam values are recorded by the detectors and used to determine the touch events. The touch sensitive device also includes a camera that captures images of touch objects. The images and variations in the beams are analyzed to continuously track the touch object before, during, and after touch events.
