  4. DEFINITION • 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. 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 • 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.

  16. ASSISTIVE TECHNOLOGY

  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.
