Touch Screen Computer

Touch screen is one revolutionary concept in the information processing world where instructions can be transmitted or obtained not by the click of a button, but just by the power of a touch. The credit for the first touch sensor goes to Doctor Sam Herst, who was an instructor at the University of Kentucky. His sensor was called the ‘Elograph’ and was patented by the University of Kentucky Research Centre in 1971. Since the touch screen has made its mark as one of the easiest and innovative interfaces to date.

Touch screen computers have become highly popular tech-gadgets in the modenr society. Touch interfaces allow users to browse computer systems just by touching links or icons in the screen. A touch screen interface has three basic components – a touch sensor, controller, and software driver.

A touch sensor is a touch sensitive clear glass panel which is placed over ta display screen. The palcement is done in a manner to allow the responsive area of the touch screen panel to cover the viewable area of the video screen. The sensor panel has an electric current running through it. A change in voltage occurs when the screen is touched, and this change determines the location of the panel where it is touched.

A controller is a PC card that brdiges connection between a PC and a touch sensitive panel. The controller is generally built inside a touch screen monitor and is responsible to determine the kind of interface needed by the PC. Integrated controllers allow connection to USB ports or serial/COM ports, and some specialized ones work with DVD palyers as well.

A software driver is what allows the touch screen and PC to work together as a single device. It is the software driver that signals the operating system of the computer to interpret the information sent by the user through the touch event. Most touch-screen drivers found today are mouse-emulation type of drivers that makes the touch screen operation similar to how a mouse would work that that particular point. However, some specialized computer systems do not need software drivers as they have there own built-in driver for the touch screen.
