The Complete History of Touch Screens


The Evolution of Touchscreen Technology by Device:

Touch screens are a relatively new invention. The first touch screen was created in 1965 and it was called the Elograph. It was only capable of recognizing one touch at a time and it was not widely adopted.

Touch screens were first used in the early 1980s, but they were not very popular because they could only recognize two points of contact at the same time and this made them less accurate than a mouse or keyboard.

In 1983, Apple released the Lisa which had a touchscreen and this is where we see the beginning of touch screen evolution as this device paved the way for future advancements in touchscreen technology.

An Overview of the History of the Pointing Device:

The pointing device is a common input for devices such as computers, tablets, and smartphones. It is used to point at or select items on the screen. The first pointing device was invented by Ralph Benjamin in 1963. He called it the “Light Pen.”

The first patent for a pointing device was issued in 1970 to Doug Engelbart. His invention was called the “Mouse.”

Advantages Of Touch Screens:

  • Touch screens have many advantages over traditional interfaces. They are more intuitive and allow for a wider range of interactions.
  • Touch screens are also easier to use when you need to enter text, because the keyboard is right there on the screen.
  • Touch screens also enable more precise control of applications and games, which is not possible with a mouse or keyboard.

Disadvantages of Touch Screens:

  • Some disadvantages of touch screens are that they can be difficult to use when you’re in a hurry or in a public place where it might be hard to see the screen.
  • They may also be difficult for people who have trouble seeing small details, such as those who wear glasses or have poor vision in general.
  • Touch screens are more expensive than traditional screens.
  • Touch screens are not as accurate as traditional screens.
