| Benefits |
Touch directly on tube—no touchscreen overlay! Preserves 100 percent of CRT brightness, clarity, antireflection and color properties. |
 |
Up to 20% brighter |
 |
Up to 80% less reflection—coin-drops can continue with sunlight on the screen |
 |
Original picture clarity not affected |
 |
Original colors not altered |
 |
Same picture quality for games with and without touch |
 |
Better for players who prefer using buttons |
 |
Smooth feel |
 |
Greater accuracy because no parallax—touch is closest to the phosphor |
 |
More durable and safer than even bonded overlays |
|
| |
| 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 |
|
| |
| Reliability |
iTouch offers outstanding reliability: |
 |
CRT faceplate, about 12mm thick, is not prone to breakage like a 3mm overlay—saves replacement costs |
 |
Faceplate harder than overlay glass |
 |
Works even with scratches |
 |
More durable to wear than capacitive |
 |
May be cleaned with any cleaner |
 |
Long-term reliability—no known wear mechanism |
 |
Built-in diagnostics on controller and touch function |
 |
Remote monitoring capability |
|

| How iTouch Works |
| The iTouch technology uses ultrasonic waves on the CRT faceplate to develop a digital map of the surface. Each X- or Y-axis has a transmitting and receiving piezoelectric transducer and a set of reflector stripes on the outside edge of the CRT. The touchscreen controller sends a five-megahertz
electrical signal to the transmitting transducers, which convert the signal into ultrasonic waves within the faceplate glass. A special pattern of reflector stripes diverts the bursts to create a uniform density of acoustic wave energy across the surface of the CRT. Reflectors on the opposite side gather and direct the waves to the receiving transducers, which reconvert them into an electrical signal.
|
 |
| A light touch with a finger, gloved hand, or soft stylus absorbs a portion of the waves. The resulting change in the received signals 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. |
