This article describes a touch-sensitive pancake device that provides touch screen functions to virtually any display monitor that is placed on the device. The touch-sensitive pancake can detect touch input locations on the display monitor cathode ray tube (CRT) as well as provide an enclosed space for additional, non-touch screen functions such as speakers, controls, etc. (Image Omitted) Most currently available touch screens require monitor design modifications to allow for touch screen mounting and cable connections. Some require an overlay that covers the display screen and reduces monitor optical quality. The touch-sensitive pancake works with conventional monitors, does not require special bezel designs, does not cover the display image, and does not require any cable connection to the display monitor.
