When do you think touchscreen technology was invented? 10 years ago, or perhaps 20? Try 40 years ago. Yep, way back in 1971, the first “Touch Sensor” was developed by Doctor Sam Hurst while he was an instructor at the University of Kentucky. In 1977, his company Elographics developed and patented five-wire resistive technology, the most popular touchscreen technology in use today.
The first Nokia touchscreen device
Touchscreens on smartphones have only really been popular for the last couple of years. So it may come as a surprise to discover that Nokia launched its first touch screen phone, the Nokia 7710 back in 2004. Its lack of keypad meant you used handwriting recognition or a stylus. One of its most innovative features at time was the ability to let you scribble a handwritten note and send it off to someone via MMS.
