introduction:
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 was called the "Elograph".
Elographics developed and patented five-wire resistive technology, the most popular touch screen technology in use today.
DEFINITION
A touch screen is basically an input device that allows a user to operate a PC or any other device by simply touching the display screen with a finger or a stylus.
A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure; a user interacts with the computer by touching pictures or words on the screen
working
