  • 2. INTRODUCTION TO TOUCHSCREEN TECHNOLOGY 1. A touchscreen is an electronic visual display which is sensitive to touch or pressure. 2. It detects the presence & location of a touch. 3. It is also the sense of finger, hands or other passive objects like stylus, light pen etc. 4. Touchscreen provides an alternative user interface to mouse and keyboard.
  • 3. HISTORY 1. 2. 3. In 1971, Dr. Sam Hurst first developed touch sensor named “Elograph” at university of kentucky. In 1974 he developed the 1st real touchscreen. In 1983 1st touchscreen computer H.P150 reached market.
  • 4. WHY TOUCHSCREEN ? 1. Enable first-time users to interface with computers instantly, without any training. 2. Durability is tested over 35 million finger touches. 3. Eliminate keyboards and mice, which many novice users find difficult to use. 4. Ensure that no space is wasted since the input device is completely integrated into the monitor.

  • 7. CONSTRUCTION A basic touchscreen has three components. 1. Touch sensor A touchscreen sensor is a clear glass panel having a touch responsive surface. The sensor has generally an electrical current or signal going through it, touching screen causes a change to the voltage & current. This change is used to detect the location of the touch.
  • 8. 2. Controller  The controller is a hardware that connects between the sensor & the PC . It takes information from the touch sensor & translates it into information that PC can understand.
  • 9. 3. Software driver The driver is a software update that allows the touch screen & computer to work together. It tells the operating system how to interpret the touch event information that is sent from the controller.

  • 11. DISADVANTAGES  Screen has to be really big, not to miss things when pressing them with your finger.  Screen  Most gets very dirty. user interfaces are not optimized for thumb operation, so a stylus is necessary.
  • 12. CONCLUSION With the growing use of touchscreen, the marginal cost of touchscreen technology is routinely absorbed into the products that incorporate it and is nearly eliminated. Touchscreen now have proven reliability. Thus, touchscreen displays are found today in airplanes, automobiles, gaming consoles, machine control systems, appliances etc. And now by j ust m f yi ng a l i t t l e, i t can odi r epl ace t he m ouse and key boar d com et el y i n pl near f ut ur e.
