The first TOUCH screen in the world(1965)

We all use touch screens on a daily basis, including smart phones, tablets, medical devices, ATMs, GPS, gaming devices, etc. But few know the scientist behind the idea: Edward Johnson, a Canadian citizen.

 E.A. Johnson is believed to be the first to develop the touchscreen in 1965. But the tablet, which was patented in 1969, 

This tablet continued in the air traffic control centers until 1995, and its flaw was that it only responds to one touch at the same time, and does not support multi-touch,

until it was later developed by the American inventor George Samuel Hearst, then the touch screen evolved over time and reached what it is Now in 2007 by Steve Jobs and his team of engineers.
