A user interacts with the computer by touching pictures or words on the screen.

5. TYPES OF TOUCH SCREEN
Resistive
Capacitive
Surface Wave

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

8. SURFACE WAVE

offers highest clarity.
considerably more expensive.

17. ADVANTAGES Ideal for web browsing, picture and movies.
Simple user interfaces, which are more intuitive (iPhone once again is a good example).
Touchscreen devices have fewer buttons .

18. DISADVANTAGES Big screen leads to low battery life.
Touchscreen means screen can’t be read too well in direct sunlight as it applies an additional not 100% transparent.
Screens get very dirty.
These devices require massive computing power which leads to slow devices and low battery life.
Finger stress.

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