Touch Screen Technology

Touch Screens
Touch screens are a clear sheet of plastic with tiny sensors that detect pressure from either a finger tip or a pointing device. When these sensors are pressed, they perform the functions found with the traditional mouse; single click, double click and drag.

A software utility needs to be installed on the computer hard drive to further customize the different settings. Touch screens are great for cause and effect and software applications that require direct select.

Good image clarity, enhanced sensitivity; and are contamination-resistant. These Integrated Touch Screen Monitors are available for Windows (3.1, 95, 98, 2000, ME, NT 4.0, XP), and Macintosh including G3 & G4. These Touch Screens utilize Resistive analog technology, which provides higher resolution.

A special thanks goes to Jason Ford of Elo TouchSystems, the company whose founder invented touch screen technology, for providing the following historical information.

In 1971, the first "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor called the "Elograph" was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology.

In 1974, the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented five-wire resistive technology, the most popular touch screen technology in use today. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.
