  2. Overview • Introduction • How does touch screen monitor know where you are touching? • Basic working Principle for resistive technology. • Basic working principle for capacitive technology. • Basic working principle for Surface Acoustic Wave (SAW) • Technology Used in India for touch screen • Working of touch screen • Touch screens Add-ons and Integrated Touch screen Monitors • What Are The Advantages of Touch screen Solutions? • Touch screen used in ATM.

  3. Basic definition • A touchscreen is an input device that allows users to operate a PC by simply touching the display screen. • Touch input is suitable for a wide variety of computing applications. • A touchscreen can be used with most PC systems as easily as other input devices such as track balls or touch pads.

  4. Working of touch screen Touch screen has 3 main components: a touch sensor, a controller and a software driver. To make a complete touch input system, a touch screen is combined with a display and a PC or other device. • Touch screen sensor- A touch screen sensor is a glass plate having touch responsive surface • ControllerThe controller used in touch screen is a small PC card that interconnects between the touch sensor and the PC. • Software DriverThe driver is software for the PC system that permits the touch screen and computer to work together.

  5. Electronic devices and computer program products for controlling a touch screen Methods for controlling touch screen oftan electronic device include: providing a soft key on the touch screen; determining an update triggering event; and, responsive to the update triggering event, relocating the soft key and/or a label of the soft key from a first location on the touch screen to a second location on the touch screen, displaced from the first location. Representative

  6. How do touch-screen monitors know where you're touching? • Touch-screen monitors have become more and more common place as their price has steadily dropped over the past decade. There are three basic systems that are used to recognize a person's touch: • Resistive • Capacitive • Surface acoustic wave

  7. Basic working Principle for resistive technology

  8. Basic working principle for capacitive technology

  9. Basic working principle for Surface Acoustic Wave (SAW)

  10. Technology Used in India for touch screen • In India Capacitive Touch screen Technology is recommended for all application because of its ability to perform in contaminated environments. Contaminants such as grease, liquid and dust do not interfere with the touch screen's operation. It is the most durable and robust touch screen available today. • Capacitive Touch screen Technologies: ClearTek Touch ScreensFor use in all Indian Conditions • All-glass touch Solution • Superior optical clarity • unmatched durability, tested to over 225 million touches .

  11. Touch screens Add-ons and Integrated Touch screen Monitors We offer two main types of touch screen products, touch screen add-ons and integrated touchscreen monitors. Touchscreen add-ons are touchscreen panels that hang over an existing computer monitor. Integrated touch screen monitors are computer displays that have the touchscreen built-in. Both product types work in the same way, basically as an input device like a mouse or trackpad.

  12. What Are The Advantages of Touch screen Solutions? The touch screen is one of the easiest PC interfaces to use, making it the interface of choice for a wide variety of applications. Here are a few examples of how touch input systems are being used today: • Control and Automation Systems • Public Information Displays • Computer Based Training • Customer Self-Service • Assistive Technology

  13. DISADVANTGES • More Expensive. • Low Resolution. • Dirty Appearance. • Complex Setup. • Not portable.

  14. Touch screen used in ATM The business goals included increasing ATM preferences usage, reducingtransaction time and increasing customer satisfaction. several design guidelines were established to guide the project: 1. Limit one clear interaction or customer action per screen2. Use clear and concise language3. Use a consistent grid for button placement4. Move all interaction to touch screen when possible (example, keypad entry)5. Improve visual and auditory feedback cues when the customer interacts with the application.

  15. Conclusion • A touch screen is a computer display screen that is sensitive to human touch, allowing a user to interact with the computer by touching pictures or words on the screen. Touch screens are used with information, kiosks computer-based training devices, and systems designed to help individuals who have difficulty manipulating a mouse or keyboard. Touch screen technology can be used as an alternative user interface with applications that normally require a mouse, such as a Web browser. Some applications are designed specifically for touch screen technology, often having larger icons and links than the typical PC application. Monitors are available with built-in touch screen technology or individuals can purchase a touch screen kit.
