This document discusses different types of touch screen technologies, including resistive, capacitive, surface acoustic wave, and infrared touch screens. It then provides details on how touch screen technology works, with the touch sensor detecting voltage or signal changes when the screen is touched. A controller connects the touch sensor to the computer and determines the interface. Touch screen drivers allow the screen and computer to work together, often emulating a mouse. The document concludes by listing common uses of touch screens and noting that while the technology has some limitations, it is widely accepted and may replace mice and keyboards in the future.

Types of Touch Screen Technologies:

4. Resistive Touch Screen

5. Capacitive Touch Screen

6. Surface Acoustic Wave Touchscreen

7. Infrared Touch Screen

8. INTRODUCTION TO THE TECHNOLOGY

11. How it Works

13. A 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

14. The 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

15. The 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.

16. 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.

17. 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
