Introduction:
A touch screen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touch or contact to the display of the device by a finger or hand. The ability to interact physically with what is shown on a display (a form of "direct manipulation") typically indicates the presence of a touch screen.
The touch screen has two main attributes.

  • It enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly with a mouse or touchpad.
  • It lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand.

Why touch Screen Technology?

  • Touch screens enable people to use computers instantly, without any training whatsoever.
  1. Touch screens eliminate keyboards and mice, which many find intimidating and cumbersome to use.
  2. Touch screens provide fast access to any and all types of digital media, with no text-bound interface getting in the way.
  3. Touch screens ensure that no space - on the desktop or elsewhere - is wasted, as the input device is completely integrated in to the monitors.

 

How Does a Touch Screen works:

A basic touch screen has three main components:

  • Touch Screen Sensor: It is a clear glass panel with a touch responsive surface. The touch sensor/panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the video screen.
  • Controller: I t is a small PC card that connects between the touch sensor and the PC. It takes information from the touch sensor and translates it into information that PC can understand.
  • Software Driver: The driver is a software update for the PC system that allows the touch screen and computer to work together. It tells the computer's operating system how to interpret the touch event information that is sent from the controller.

Construction:

Technologies used in the construction of touch screen are as follows.

  • Resistive
  • Surface Acoustics wave
  • Capacitive
  • Strain gauge
  • Optical imaging
  • Dispersive signal technology
  • Acoustic pulse recognition
  • coded LCD

Advantages:

  • User friendly
  • fast response
  • error free input
  • easy to install
  • Use finger, finger nail, gloved hand, stylus or any soft tip pointer to operate.
  • Compatible with windows, Macintosh and Linux.
  • Makes computing easy, powerful and fun.

 

Disadvantages:

  • Stress on human fingers when used for more than a few minutes at a time.
  • Touch screens can suffer from the problems of fingerprints on the display.
  • Touch screen devices usually has no additional keys (see the Iphone) and this???????? means when an app crashes, without crashing the OS, you cant get to the main

??????????? menu as the whole screen becomes unresponsive.

  • These devices require massive computing power which leads to slow devices??? and low battery life.
  • Screen has to be really big not to miss things when pressing them with your?????? finger.

???? Applications:

  • Public Access:? Museums, library resources guides, corporate information, public transportation schedule or status.
  • Business:? Restaurants, Grocery stores, Banks and financial reporting, hospital and hotel directories.
  • Entertainment: ??Interactive computer games, casino.
  • Government:? Military control system, scientific lab research.

 

Conclusion:
Today, a large share of population is pc literate, yet the touch screens have been adopted by computer users of all abilities because it is simple, fast and innovative. In future there would be no use of mouse and keyboard as they would be replaced by touch screens.
