IntelliTouch technology
The IntelliTouch touchscreen is a glass overlay with
transmitting and receiving piezoelectric transducers for both
the X and Y axes. The touchscreen controller sends a five-
megahertz electrical signal to the transmitting transducer,
which converts the signal into ultrasonic waves within the
glass. These waves are directed across the front surface of
the touchscreen by an array of reflectors. Reflectors on the
opposite side gather and direct the waves to the receiving
transducer, which reconverts them into an electrical
signal—a digital map of the touchscreen surface.
When you touch the screen, you absorb a portion of the
wave traveling across it. The received signal is then
compared to the stored digital map, the change recognized,
and a coordinate calculated. This process happens
independently for both the X and Y axes. By measuring the
amount of the signal that is absorbed, a Z axis is also
determined. The digitized coordinates are transmitted to the
computer for processing.
