    Abstract: A user interface input apparatus (10) and method allows the detection of when and where a user touches a surface of a translucent screen (12) by the processing of imagery generated by a camera that views an opposite surface of the screen, An input device (10) and system includes a translucent screen (12); an image capture device (14) located for imaging a first side of the screen opposite a second side where user interaction occurs; and an image processor (20) 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.

    Abstract translation: 用户界面输入装置（10）和方法允许通过处理由观看屏幕的相对表面的相机产生的图像来检测用户何时何地触摸半透明屏幕（12）的表面。输入装置 （10）并且系统包括半透明屏幕（12）; 图像捕获设备（14），其被定位成用于对屏幕的第一侧进行成像，所述第一侧与发生用户交互的第二侧相对; 以及图像处理器（20），其耦合到所述图像捕获装置的输出，以通过由所述触摸区域相对发出的光的强度变化来确定人在屏幕的第二面上的哪个和何时触摸屏幕的区域中的至少一个 到周边地区。
