摘要： We describe a touch sensing system projecting light defining a touch sheet above a surface and a camera to capture a touch image of light scattered by a pen intersecting the touch sheet. A signal processor identifies a lateral location of the pen. The pen includes a light source to provide a light signal, and the system also includes two photodiodes to detect the signal from the pen. The touch detection is augmented by modelling the signals received at the photodiodes, dependent on the distance and angle of a pen, and using this to derive a probability of the observed received signals given the pen location determined from the touch sheet. This information can be used, for example, to allocate identities to the pens.

摘要： We describe a touch sensitive image display device. The device comprises: an image projector to project a displayed image onto a surface in front of the device; a touch sensor light source to project light defining a touch sheet above the displayed image; a camera directed to capture a touch sense image comprising light scattered from the touch sheet by an object approaching the displayed image; and a signal processor to process a the touch sense image to identify a location of the object relative to the displayed image. The camera is able to capture an image projected by the image projector, the image projector is configured to project a calibration image, and the device includes a calibration module configured to use a calibration image from the projector, captured by the camera, to calibrate locations in said captured touch sense image with reference to said displayed image.
