Abstract
A photoelectric sensing array assembly is disclosed for use in combination with an optical touch screen that is externally adaptable to a video monitor for serving as an input device to an electronic device connected to the video monitor. More particularly, the photoelectric sensing array utilizes interconnectable segment components of a variety of standardized sizes to permit the construction of optical touch screens of any dimension. In one implementation, first and second pairs of rails are mounted in a frame-like configuration in photoelectric communication for detecting the presence of an opaque object disposed therebetween. Each one of the rails includes a plurality of interconnected segment components having an arrangement of photoelectric elements disposed thereon.
