Abstract
Apparatus and methods are provided for converting a display into a touch display. One or more optical sensors are arranged proximate the display. A processor receives a signal from the optical sensor(s) and, based on the signal, executes instructions for: (i) determining a distance between a pointer device and a surface of the display signal; (ii) determining a position of the pointer device on the surface of the display; (iii) when the distance is less than a threshold detection distance and greater than a threshold touch distance, providing an indication on the display that the position of the pointer device has been determined; and (iv) when the distance is less than the threshold touch distance, taking an action indicative of contact between the pointer device and the surface of the display.
