Optical touch tomography

An optical touch-sensitive device has the capability to determine touch locations of multiple simultaneous touch events. The touch events disturb optical beams propagating across the touch sensitive surface. With multi-touch events, a single beam can be disturbed by more than one touch event. In one aspect, a non-linear transform is... Rapt Ip Limited

Instrument detection with an optical touch sensitive device, with associating contacts with active instruments

An optical touch-sensitive device detects touch events caused by instruments (e.g., pens, styluses) and distinguishes these events from touch events caused by fingers. In some embodiments, different instruments can also be distinguished. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by... Rapt Ip Limited

Vibrated waveguide surface for optical touch detection

An optical touch-sensitive device includes a planar optical waveguide structure having a planar optical waveguide, and transducers that are able to activate to vibrate a top surface of the planar optical waveguide structure. The device also includes multiple emitters and detectors. The emitters and detectors are arranged along a periphery... Rapt Ip Limited

Detecting multitouch events in an optical touch-sensitive device using touch event templates

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... Rapt Ip Limited

Low power operation of an optical touch-sensitive device for detecting multitouch events

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....
