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.
