The invention of a Touch Screen has truly changed the way we interact with our gadgets everyday. Every gadget works on the same fundamental principal as they all feature a computer or simply a processing device built in which is the brain of that gadget.

The touchscreen entered main stream technology in the 2000’s.Although the first touch screen was designed by E.A. Johnson around 1965 it became popular and wide scale integration into gadgets after 2002. You might credit Apple computers for ushering in the touch screen generation by introducing it in the revolutionary iPhone. I remember when I bought my first generation iPhone a few years ago; my mother would not believe it was really a phone. She thought it was one amongst the useless, unwanted gadgets that I spend all my funds on. She could not envision a phone without keypad to dial the phone number until I personally showed her exactly what the people at apple computers had done. I do believe apple put the sole home screen button on the phone purposely to let people know that they did not need keypads and buttons anymore.At the moment touch screens are used as the preferred input device in nearly all new computer or gadget. Touch screen are already utilized in ATMs, information kiosks, watches, medical equipment, in-flight entertainment systems, navigation and audio systems, machinery control terminals in factories and phones.

Touch screens have been accountable for bringing in the revolutionary generation of computers. The laptop replaced the desktop because of the portability and mobility. Now we have tablets replacing laptops. Tablets employ the touch screen as a primary input device; you don't have keyboard or even a track pad. You do not need a stylus either all you need are your fingers. Touch screens can handle recognizing multi gestures which mean you could use more than one fingers together to type or touch icons to launch programs.
Microsoft was the first to make a foray into tablet computers in 2002 by launching the Windows XP tablet edition but was not widely accepted by consumers. The reason for this may have been because along with the touch screen you also required the external keyboard. The iPad was responsible for making tablet computer favored by consumers. It did not feature an external keypad just like the iPhone had one button since there wasn't any need for buttons and keys.
Touch screens are not fragile input devices anymore, the new generation of gorilla glass 2 makes touchscreens fairly durable and protected from scratches. You no longer need to bother with scratches on screen when you put your smartphone in your pocket along with your keys and coins.
A touch screen truly reminds me of that famous Michelangelo painting on the roof of the Sistine chapel called the creation of Adam. The touch screen makes us feel like gods as we can control a powerful computer or machinery just with the usage of our fingertips.
