Abstract
A touch screen system is provided herein for use with a commanded system requiring high integrity. The touch screen system includes, but is not limited to, a display screen configured to present information to an operator. A sensor array is arranged proximate the display screen to detect a touch on the display screen and to generate a set of touch position coordinates corresponding to a location of the touch. A processor is operatively coupled to the display screen and is configured to command the display screen to arrange a plurality of touch target images such one of the touch target images is a high integrity touch target image. The high integrity touch target image has a unique X-coordinate that is not shared by any other touch target image and a unique Y-coordinate that is not shared by any other touch target image.
