From a musical instrument to the smartest computer ever
A brief history of touch screens
In 1948 the Electronic Sackbut made its debut as the first ever touch screen technological advancement.It was a musical instrument that allowed its users to change volume with the differenciating pressure that one plays with. The next major technological jump came in 1972 when PLATO (Programmed Logic for Automated Teaching Operations) Originally, PLATO was built by the University of Illinois and functioned for four decades, offering coursework to UIUC students, local schools,and other universities.It was primarily used to allow students to answer questions through an infrared red touch panel.In 1998( the year many of us were born) University of Delaware academics John Elias and Wayne Westerman created the finger pad which was effectively a touch keyboard that you could draw on as well as other things.In 2005 Apple bought Fingerworks and all there software and began work on the iPad. From then on Touch screens have continued to evolve and the uses of these computers are far beyond what meets the eye.
