The touch screens have more history than we can imagine, the first tactile technology interface was invented in 1971 by Dr. Samuel C. Hurst, and became very popular in POS (Point of Sale Terminals), ATMs and in PDAs, these last ones had the need to use a Stylus or plastic pencil for its correct operation. Later, products such as video game consoles, personal computers and smartphones have been incorporated into this touch screen technology.
Currently, they have become so popular and claimed by users, that we can find them in almost any technological product; televisions, music players, portable GPS navigators and embedded as standard by the car manufacturer, even coffee makers and refrigerators already include this technology in tremendous boom and demand.
One of the first personal computers to go on sale using touch screen technology, was the HP-150, which back in 1983 used a series of sensors surrounding the entire screen to detect everything that was not transparent in the radius of the own screen.
Actually, it had little to do with current technology, since the HP-150 itself had a 9 “tube screen, and the sensors that it had scattered around the contour of the casing, acted as a barrier that detected any object that this barrier would cross, so a simple flying insect was considered a user of the computer itself.
What is a touch screen?
A touch screen is a peripheral input and output for the device in which it is installed, acting as a direct intermediary between our orders and what the device in question should do. The orders in question can be given as their own name indicates, in a tactile way, or also by means of a pencil or Stylus, which depending on the screen, should be of optical technology. There are several types of touch screens, and they work in a completely different way depending on the technology used and the technical characteristics. Whatever differences in characteristics they have, they work with the same principles.
