Touchscreen technology may seem like a fairly recent discovery, but, in reality, touchscreens have been around for 50 years! The first finger-driven touchscreen was invented in 1965 by E.A. Johnson. He published an article about his discovery in Electronics Letters along with a diagram describing a type of touchscreen mechanism that many of our phones use today— capacitive touch.
