    摘要: A user interface input apparatus and method allows the detection of when and where a user touches a surface of a translucent screen by the processing of imagery generated by a camera that views an opposite surface of the screen. An input device and system includes a translucent screen; an image capture device located for imaging a first side of the screen opposite a second side where user interaction occurs; and an image processor coupled to the output of the image capture device to determine at least one of where and when a person touches an area on the second side of the screen by a change in intensity of light emanating from the touched area relative to a surrounding area.
