Introduction
Touch screen is a touch-sensitive transparent panel which is used to point the objects on the screen by simply using your finger.
Evidently, the first touch
screen was a capacitive type
A touch Screen is based on
CRT(Cathode Ray Tube) Technology,
That accepts direct On-screen input
The Display Screen Has A Sensitive
Glass Placed on it And We Could the Desired Input By
Touching It.
The first ever touch screen was
developed by E.A Johnson at the Royal Radar
Establishment
A touch screen is an electronic visual display capable of ‘detecting’
and effectively ‘locating’ a touch over
its display area.
History
E.A. Johnson at the Royal Radar Establishment,
Malvern, UKPeriod of Study

Inspiration led to PLATO project (1972)

Applications
For the people worried about hygiene,
most devices are easy to clean, some are even dirt, dust and grease resistant
Touch screen devices have limited buttons that will possibly break after 3 – 4
years
Having less or not buttons means that you can put
more effort into having a big screen
Touch screen devices usually have more simple user interfaces Ex. IPod
Apps
Touch screens are easy to use helping more people
get used to using computers
In direct sunlight it is much less effecting and most of the time very difficult to read the screen
The screen has to be big enough to be able to touch the
buttons without missing
The screens will get very dirty
If a touch screen devise were to crash the whole screen would be
unresponsive, and because of the lack of buttons revoering it would be very
difficult
Having a big bright screen and needing massive computing
power to run this means a very low battery life

Statistical Approach
Future
“ Tomorrow’s touch screens will not only recognize finger pressure, but interact with a
host of touch sensors wrapped around the body of the phone. ”
In the near future touch screen would conquer every
aspect of technology
