INTRODUCTION TO THE TECHNOLOGY
http://ambeelectronics.com/
Introduction A touch screen is computer display screen that is sensitive to
human touch. The display screen has a sensitive glass overlay placed on it
and we could give the desired input by touching it. A touch screen kit includes a touch screen panel, a controller
and a software driver. Internal touch screen kits are available but require
professional installation because the must be installed inside the monitors.

Working of TouchscreenMain Components : -
Touch Sensor Controller Drivers

Touch SensorA touch screen sensor is a clear glass panel with a touch responsive surface
The sensor generally has an electrical current or signal going through it and touching the screen causes a voltage or signal change

ControllerThe controller is a small PC card that connects between the touch sensor and the PC
The controller determines what type of interface/connection you will need on the PC

DriversThe driver is a software that allows the touch screen and computer to work together
Most touch screen drivers today are a mouse-emulation type driver.

Public Information Displays::: Tourism displays, Trade show display
Customer Self-Services::: Stores, Restaurants, ATMs, Airline ticket terminals and Transportation hubs.
More uses... Digital jukeboxes, Computerized gaming, Student Registration systems, Multimedia software , Scientific applications etc.
Applications

Direct pointing to the objects.
FastFinger or pen is usable (No cable required)
No keyboard necessary
Suited to: novices, application for information retrieval etc
Low precision by using finger
User has to sit or stand closer to the screen
The screen may be covered more by using hand
No direct activation to the selected function

Though the touch screen technology contains some limitations it’s very user friendly, fast, accurate, easy for the novices & fun to operate. It has been widely accepted. And now by just modifying a little it can replace the mouse and key board completely in near future
