This article describes a tactile switch locator and graphic concept for a touch-sensitive graphic display system which provides a low-cost tactile locator for soft switches and graphics features to minimize visual concentration. Touch-sensitive panels are rapidly finding wide applications as input mechanisms to digital computers, replacing the conventional hardswitches and in some cases augmenting or replacing a keyboard. When the display is touched, the location of the touch is sensed via one of several established techniques, such as IR or conductive overlays. When switching action results, the switch function is referred to as a softswitch. Softswitch action, in general, results from contacting a hard surface that gives no locator assistance or tactile feedback.
