Dependable low maintenance technology which allows touch sensing through an optical protective screen such as a shop window or layer of glass. Extensively used in retail and leisure for self drive touch enabled applications.

The electronic controls effectively divide the screen into pixel size sensing cells, using microfine wires which are barely visible to the naked eye, on a powered display. These wires are connected to a controller board, and an oscillation frequency is established for each wire. Touching the glass causes a change in the frequency of the wires at that particular point, the position of which is identified and calculated by the controller. The front glass of the touch screen acts as a dielectric and enhances the capacitance of the touch screen.

Flexible low cost technology designed for interactive kiosk or touch enabled digital messaging in high volume environments. Can be implemented in a wide range of installations and easily integrated into a custom kiosk housing.

The U-Touch screen is a frame with embedded IR-LEDs and photo transistors hidden behind the bezel of the touch frame. Each of the IR-LEDs and photo transistors is set on the opposite sides to create a grid of invisible infra-red light. The touch screen controller pulses the LEDs to create a grid of IR light beams. When the screen is touched, this creates an interruption in the light beam which is measured by way of an X and Y coordinatewhich is sent back to the host computer.
