| Benefits |
| Surface wave technology on pure-glass touchscreens for superior image clarity, resolution, and light transmission: |
 |
Brighter picture than with other overlays since no layers or coatings |
|
Less reflection as no metallic coatings |
|
Original colors not altered |
|
| |
| Same fast, accurate, stable performance as iTouch technology: |
|
Fast and sensitive—faster than capacitive in two-handed play |
|
4095 x 4095 resolution |
|
No drift with temperature or humidity—touch smaller targets accurately every time |
|
No need for periodic recalibration |
|
Not affected by surrounding metal, stray capacitances, RFI, EMI, etc. |
|
Not dependent on the user—works with dry or callused fingers |
|
No earth/ground problems—works as well with 2-prong A/C |
|
Never an incorrect, averaged double-touch from two players |
|
Z-axis for pressure can add a new dimension to games |
|

| How IntelliTouch Works |
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 transducers, which convert the signals into ultrasonic waves within the glass. These waves are directed across the front surface of the touchscreen by a special pattern of reflector stripes. Reflectors on the opposite side gather and direct the waves to the receiving transducers, which reconvert them into an electrical signal—a digital map of the touchscreen surface.
A light touch with a finger, gloved hand, or soft stylus absorbs a portion of the wave. The resulting change in the received signal is analyzed by the controller and digitized into X and Y coordinates. In addition to sensing the location of a touch, surface wave is the only touch technology that can also sense the pressure of a touch-the Z-axis-by measuring how much signal was absorbed. |
