Even before touch screen phones were invented, the touch screen technology already existed on some of the devices we frequently use before – such as the ATM machine for one.
The ATM machines evolved from 12 button numeric keypads to text commands on the screens that the user put some light touch on. And viola – the transaction is successful in a matter of seconds instead of effortlessly punching buttons. The touch screen technology offers faster processing of actions because it complements the natural movement of a human body. It does not require additional efforts such as punching. Furthermore, it lessens the actions needed because it combines it seeing and touching in one frame. For example, the ATM machine requires the user to look at the screen and then punch the numbers corresponding to his choice on the keypad positioned below the monitor. With the touch screens, the monitor and keypad are combined in one and the user automatically selects his action from the very screen he is looking at. Choices are now easier to see and make thus providing more convenience at a faster rate.
Today, almost every technology gizmo has the touch screen technology - digital cameras, MP3 players, laptops, and more especially phones. Besides the convenience and speed, the touch screen technology also has long term ergonomic benefits which most people might not be aware of. It has ergonomic benefits such as preventing hand and wrist injuries. The awkward position and prolong usage of the hands and wrists when using gadgets causes injuries such as Carpal Tunnel Syndrome. So in the end, the touch screen is not just a technology fad because it actually has great benefits for its users also.
