| description | A touch screen display includes a diffuser screen, a projector, a camera, an infrared (IR) light source, and a controller. The diffuser screen has a front surface and a rear surface. The projector is disposed to project images onto the rear surface of said diffuser screen, and the images are visible to a user through the diffuser screen. The camera is disposed behind the diffuser screen and aimed to capture images of a pointer near the front surface of the diffuser screen. The IR light source is disposed to direct IR light toward the rear surface of the diffuser screen, so the rays of incident IR light form an acute angle with respect to the rear surface of the diffuser screen, and so that any of the incident IR light reflected off the rear surface of the diffuser screen does not enter the camera. |
