Sistema de display e método

摘要

A display system (AP1) has plural cameras (11L an d11R) having fields of view (31L and 31R) that extend more orthogonal to than parallel to a display screen (21) for viewing distal objects. Reflectors (33L and 33R) redirect touchscreen light (36) from a direction along the display screen to a direction toward the cameras. A video processor (19) locates a 2D position relative to the display screen of an object proximate to the display screen as a function of images generated by the cameras in response to the touchscreen light.
