Touch Screen Technology Has Been Appearing Since 1948

The term touch screen or touch screen is a computer input that works with the touch of a screen display using a finger or a digital pen. Now touch screen has been widely applied in various objects around humans, such as smartphones and laptops.

Did you know that the touch screen has been around for a long time. Technology historians say that touch screen technology starts from the music industry with a touch-sensitive synthesizer.

Launched from Baanro, touch screen was developed in 1948 starting from Electronic Sackbut Hugh Le Caine (composer from Canada). This device involves the use of a piano keyboard and control board. So, the people who play the instrument use touch to control the volume through the pressure on the button and set the music texture through the control board.

Fast progress in 1965, where touch screen technology was applied on screen by E.A Johnson. The screen comes from Royal Radar Establishment, UK and is a major version of touch screen technology, which is ultimately used in ATMs and all types of customer service outlets.

The touch screen was first recognized and used by the University of Illionis, which developed PLATO IV in 1972. The University of Illinois has developed a computer system for education throughout the 1960s. The system uses an infrared touch panel that students use to answer questions.

In 1982, touch screen began introducing multitouch technology. This multitouch involves using a video camera capable of interacting with a computer. This concept began to be used on screen in 1984 and its first use allowed people to manipulate graphics using their fingers.

This technology continues to grow in the era of 80 to 90 until the introduction of keyboard and mouse which was eventually taken over by Simon Personal Communicator Phone in 1993. In 2007, the use of touch screen technology became popular in consumer devices and its popularity soared to now.

Although simple, it paves the way for developing a touch screen as it is known today.
