College(CSE) dizizjyothi@gmail.com Slide 2: What is a Touch Screen? A touch screen is an Electronic Visual Display that responds when it detects a touch on its Surface Evolution of Touch screen : The touch screen was derived from the digitizing tablet. The digitizing tablet was invented by Sam Hurst in 1971. It was designed to allow scientists to record data from graphs by placing the graph on the tablet and pressing the paper against the tablet with a stylus. Elographics became the first commercial producer of digitizing tablets Evolution of Touch screen How Does a Touchscreen Work? : How Does a Touchscreen Work? A basic touchscreen has three main components: 1 Touch sensor; 2 Controller; 3 Software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system. Touchscreen Technology : Resistive touchscreen Capacitive touchscreen Infrared touchscreen Surface acoustic wave (SAW) touchscreen Touchscreen Technology Resistive touchscreen : Resistive touchscreen Capacitive touchscreen : Capacitive touchscreen Infrared touchscreen : Infrared touchscreen SAW touchscreen : SAW touchscreen Applications : Public information displays Customer self service Computer based training Assistive technology Applications Advantages : Touching a visual display of choices requires little thinking and is a form of direct manipulation that is easy to learn. Touch screens are the fastest pointing devices. Touch screens have easier hand eye coordination than mice or keyboards. No extra work space is required as with other pointing devices. Advantages Disadvantages : User's hand may obscure the screen. Screens need to be installed at a lower position and tilted to reduce arm fatigue. Some reduction in image brightness may occur. They cost more than alternative devices. Disadvantages So What ‘s Next? : So What ‘s Next? Slide 14: You do not have the permission to view this presentation.
