IntelliTouch is a technology for surface acoustic waves (SAW). It features high image quality and a long service life.
The IntelliTouch touchscreens are based on original technology using the principle of surface acoustic waves. The screen is a glass panel that allows you to get the highest quality image on your touch monitor. The surface of IntelliTouch screens is able to withstand mechanical damage. Touch the screen with your finger, gloved hand, or a stylus and you will get an exact response to the touch. The IntelliTouch touchscreens have proven themselves in retail, education, and smart buildings.
Piezoelectric transducers are located at the corners in the non-working part on the glass panel of the screen, corresponding to the shape of the monitor matrix. The controller sends an electrical signal to the transducers, which turn the signal into an acoustic wave. The acoustic wave travels across the surface of the glass panel and is reflected by an array of sensors around the perimeter. Receiving sensors collect the reflected wave and send it back to the piezoelectric elements. The wave is converted into an electrical signal, which is analyzed by the controller.
When you touch the screen, part of the surface wave is absorbed. The received signal is compared with the standard, changes are determined, and coordinates are calculated. This process is carried out independently along two axes - X and Y. A feature of IntelliTouch is the ability to determine the force of touch - the Z coordinate. The coordinates are transferred to the computer.
Technical comparison with other technologies
Elo sensor technologies (resistive and surface acoustic waves) are designed for use in various environmental conditions. IntelliTouch technology was patented in 1987. Since then, the line has been complemented by SecureTouch vandal-resistant screens. IntelliTouch technology is designed for public use.

Capacitive technology
| SAW technology | Capacitive technology | |
| Definition | IntelliTouch and SecureTouch: Glass only . iTouch: The image is clear, with contrast and color depth the same as without a touchscreen. |
Glass with a metallic coating. |
| Translucency | 90-92% (on ASTM D1003). iTouch: 100%. |
85% - with a distance between the surfaces of 550 nanometers. |
| Reflection / Glare | No metallic coatings. There are screens with and without anti-reflective coating. iTouch: No need to use anti-reflective coatings. The reflection is 80% lower than in screens made by capacitive technology. |
Metal coatings enhance reflection. There are screens with and without anti-reflective coating. |
| Color purity | Does not change. | Metallic coatings add a shade of yellow to especially white colors. |
Clarity and reliability
The IntelliTouch touchscreens provide a bright, clear image, even when used in public places.
