Recently I along with two of my class mates is working on a add-on touch screen system that can be set on any existing CRT or TFT monitors. The main idea to detect the touch is detecting the coordinates as an obstruction crossover in an invisible IR grid. The data will then be processed and will manipulate the mouse registers making our finger the mouse pointer.
