Touch screen technology allows users to interact directly with digital displays using only finger touches. There are three main types of touch screens: resistive, capacitive, and surface wave. Resistive touch screens use pressure, capacitive uses finger touch, and surface wave offers highest clarity but is most expensive. Touch screens are used for public displays, self-service kiosks, training, mobile devices, and assistive technologies. They provide simple, intuitive interfaces but can have short battery life and dirty screens. Overall, touch screens provide a user-friendly experience.

Touch Screen Technology

2.  INTRODUCTION
 A touchscreen is an electronic visual display that
the user can control by touching it.
The touchscreen enables the user to interact
directly with what is displayed, rather than using
a mouse touchpad or any other intermediate
device

CONCLUSION

4.  A touch screen is a computer display
screen that is also an input device.
 A user interacts with the computer by
touching pictures or words on the
screen.

5. Resistive
Capacitive
Surface Wave

6. Resistive touchscreens are pressure
sensitive, so they can be operated with any
input device, including a gloved hand or
stylus.
easily damaged by sharp objects.
they offer only 75% clarity.

7.  RESISTIVE TOUCH SCREEN

8.  Capacitive screens are resistant to
outside elements, making them very
durable.
 capacitive panels must be touched with
a finger.
 maintains high clarity.

9.  CAPACITIVE TOUCH SCREEN

10. Surface wave touch screen are more
advanced technology that provides
high durability and can be operated by
either human touch or stylus.
offers highest clarity.
considerably more expensive.

11.  SURFACE WAVE TOUCH SCREEN

12.  Public Information Displays
 Customer Self-Services
 Computer Based Training
 Assistive Technology

13.  PUBLIC INFORMATION DISPLAYS

14. TOUCH SCREEN MOBILE

15.  ASSISTIVE TECHNOLOGY

16. Ideal for web browsing, picture and movies.
Simple user interfaces, which are more easy to
use. (iPhone once again is a good example).
Touchscreen devices have fewer buttons .
No extra peripherals are needed.
Time saving.

17.  Big screen leads to low battery life.
 Screens get very dirty.
 These devices require massive computing power
which leads to slow devices and low battery life.
More expensive than alternative devices.

18. Though the touch screen technology contains
some limitations but it’s very user friendly, fast,
accurate, easy for the novices & fun to
operate.
