The facility of easy navigation through the different types of applications and folders has made it easier for a mobile user to make the best use of his or her phone. This easy to use and interactive technology is preferred by all most all the people in the world today as they offer the necessary convenience.
The evolution of this technology can be dated back to the year 1971. It was invented by Dr. Samuel Hurst. There is an interesting story behind its invention. When Samuel was graduating he had to study many books that used to consume much time. In order to save time, Samuel invented a new technology called Elograph that enabled him to enter data more quickly. After a span of five years, the first ever touch screen technology or what was known as the five wire resistant methods was invented.
In the recent past with the rapid development of science, this technology became the part and parcel of our everyday lives. From mobile phones to ipads to the tablets and ATMs, touch screen has today become one of the most preferred technology, which is used almost everywhere. The IPod Touch screen technology is one of the most advanced among all the leading mobile phone brands in India. The four inch retina display of iPod is just perfect for a one handed use of the gadget so that one can have complete control over it.
This feature is very interactive and at the same time enables a user to easily navigate through all the applications with a single touch of the finger. The sensors of the phone can easily detect the movement of fingers.
As far as the mobile phones are concerned, resistive or the pressure sensitive touch screen is used in most of the mobile phones. It is not in any way affected by water or dust. There are three types of pressure sensitive touch screens; they are 4-wire, 5-wire and 8-wire. Among these three, 5-wire is the most commonly used touch screen system. Here, small plastic dots are used in between two layers. Until and unless any pressure is used, the screen does not react to any kind of touch.
Whenever the screen is touched, electricity passes through each one of the layers and a chain is formed. The electricity is then measured which in turn determines the touch. This is sensitive to only one touch at a time and is one of the least expensive methods of all the technologies that are used.
With the convenience that the touch screen technology has provided to the human beings, one can be very sure of the fact that it is never going to be out of fashion. One can perform all the functions faster thereby saving a lot of time. A research done by Mitsubishi Electric Research Laboratories suggests that this technology has reduced about 20 percent of the response time.
