Elo Touch Technology

Elo TouchSystems has no less than 8 touch technologies which are used in their touch screen terminals. Each technology has it specific characteristics and properties. By means of a number of criteria you can examine which touch screen techology suits your application best.

The market in which you wish to use the touch screen technology is already an important fact. The way touch monitors are used clearly differs from market to market.

Eight Elo touch technologies used in touch monitors

AccuTouch, also called 5-wire resistive touch technology, is one of the most successful Elo technologies. This touch technology uses a polyester overlay , which makes it water and dust resistant. The AccuTouch technology is reliable and precise and can be touched with any stylus even with wet hands.

AT4 is just like AccuTouch a resistive Elo technology. The difference is that these 4-wire touch screens are only available in smaller dimensions. You can find these touch screens especially in pocket PC's, GPS systems, domotica and light industrial applications.

IntelliTouch is a technology extremely suitable for public use. IntelliTouch exits out of a glass panel with reflectors, senders and receivers. Emitters send sound waves over the panel and when one touches the panel with a finger, the sound waves are absorbed at that point. The intelligent controller will recognize this as a touch.

SecureTouch works according to the same principle as IntelliTouch, but has a thicker hardened glass plate. This technology is therefore ideal for busy places or spaces without supervision, for example for selfbanking, ATM's or museums.

iTouch is the third variant of the "surface wave" family. The touch screen sensors are introduced directly on the existing CRT monitors. This way picture quality is preserved. An additional advantage is the attractive price of these touch screen monitors.

CarrollTouch combines a number of advantages of both AccuTouch and IntelliTouch. This touch technology works on the basis of infra red indicators which are interrupted at contact. This guarantees an accurate and fast functioning under nearly all circumstances. Also outside or in surroundings where vandalism can occur, CarrollTouch provide perfect results.

Projected Capacitive makes it possible to use shop windows as a touch screen. Also outdoor and in risky surroundings Projected Capacitive has its advantages. The Projected Capacitive technology can detect a touch through the glass. Touch screen monitors with Projected Capacitive technology can be installed behind a window.

The Surface Capacitive touch technology creates a field from the four angles of the monitor. Where the touch screen monitor is touched, one disturbs the field and the controller measures the coordinates of the contact. Possible markets for Surface Capacitive are mainly Point or Information and gaming.
