If you think that your iPhone is the first device on the planet to have a fancy looking touchscreen, you surely know too little about technology. Of course, the iPhone did play the key role in popularizing the technology to a greater extent, but that was definitely not where it all started.
Before we get deep into history, let’s first know what a touch screen is. A touch screen in easy words is a screen that’s sensitive to a touch of a finger or a stylus. A touch screen is basically constructed out of three major components – the touch sensor, the controller and the software. The touch sensor is a panel having a touch-responsive surface. The controller is responsible for converting voltage changes into signals that a computer can receive. Lastly, the software transfers the information from the controller to the computer.
Now, let us delve further into its history
It was in 1965, that E. A. Johnson a British inventor first described in an article his work on capacitive touch screen. Later in 1970 engineers from CERN developed a unique transparent touchscreen which was put in use in 1973. After numerous theories and experiments we now have touchscreen on our mobile phones, tablets, laptops, microwaves and even watches.
In 2002, Windows XP Tablet equipped with touchscreen feature greatly accelerated the use and preference of touchscreen amongst the users. Followed by the launch of Apple iPhone in 2007 equipped with a highly user intuitive touchscreen which successfully got users addicted to this technology.
It comes as no surprise that Nokia, Samsung, HTC, Apple, LG, Motorola offer touchscreen devices in order to capture their market share keeping in mind the preferences of today’s customers.
