History Of Touchscreen

 The "Elograph" was not transparent like modern touchscreens; however, it was a significant milestone in touchscreen technology.

In 1974, the first true touchscreen incorporating a transparent surface was developed by Doctor Sam Hurst and Elographics.

In 1977, Elographics developed and patented five-wire resistive technology, the most popular touchscreen technology in use today. Touchscreens have subsequently become familiar in everyday life.

From 1979–1985, the Fairlight CMI (and Fairlight CMI IIx) was a high-end musical sampling and re-synthesis workstation that utilized light pen technology, with which the user could allocate and manipulate sample and synthesis data, as well as access different menus within its OS by touching the screen with the light pen.

Display manufacturers and chip manufacturers worldwide have acknowledged the trend toward acceptance of touchscreens as a highly desirable user interface component and have begun to integrate touchscreen functionality into the fundamental design of their products.
