Abstract
A high integrity touch screen system includes, but is not limited to, a display screen, a first sensor array to detect a touch on the display screen and to generate a first set of touch position coordinates, a first processor connected to the first sensor array and configured to receive the first set of touch position coordinates, a second sensor array to detect the touch on the display screen and to generate a second set of touch position coordinates and a second processor connected to the second sensor array and configured to receive the second set of touch position coordinates. The first processor and the second processor cooperate to compare the first set of touch position coordinates with the second set of touch position coordinates and to invalidate the touch when the first set of touch position coordinates and the second set of touch position coordinates do not substantially coincide.
