The document discusses different aspects of touchscreen technology. It begins with an introduction and overview of how a touchscreen works, including that it uses a touch-sensitive clear glass panel and controller to determine inputs. It then describes four main types of touchscreen technologies - resistive, capacitive, surface acoustic wave, and infrared. Applications of touchscreens are discussed such as displays, self-service kiosks, gaming, and mobile phones. Both advantages like ease of use and disadvantages like low battery life are outlined. The document concludes by stating that though touchscreens have limitations, the technology is widely accepted and being improved.

6. 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

7.  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

16. ADVANTAGES
User friendly
Fast response
Use finger, fingernail , stylus or any soft tip
pointer
Easy to clean
Does not interfere mouse and keyboard
Make computing easy, powerful and fun

17.  DISADVANTAGES
Having a big bright screen and needing massive
computing power to run this means a very low
battery life
In direct sunlight it is much less efficient and most
of the time very difficult to read the screen
If a touchscreen device are to crash the whole
screen would be unresponsive, and because of the
lack of buttons recovering it would be very
difficult.
 Fingerprints of the user obscure the screen if not
handled carefully.Touchscreen

18. Though the touch screen technology contains some
limitations but 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
