Standard applications
Most of the touch screens offered by GGI International operate similarly to a computer mouse. Once the software driver for the touch screen is installed, it emulates computer mouse-like functions. Touching the screen is basically the same as clicking a computer mouse at a similar point on the screen. The user-friendly touch screen interface can be less intimidating and easier to use than some other input devices in certain specific applications such as:
- Information Terminal (tourist or commercial)
- Retail and restaurant systems
- Control and automation systems
- Financial applications
- Interactive guide for museum or other scientific application
- Computerized gaming
Standard characteristics
Three components are typically included with a touch screen display: a software driver, a touch sensor and a controller. The touch screen, being strictly an input device, requires to be combined with a display and a computer processor to be considered a complete tactile input system.
- Touch Sensor: A touch screen sensor is, among other things a clear glass panel with a touch responsive surface. The touch sensor panel is mounted above the LCD display diffusing the visual contents so that the active area of the panel covers the viewing area of the LCD display. The active area of the touch screen needs to completely cover the LCD viewing area so that the programming of the contact areas can be effective over the whole viewing area of the display.
- Controller: A small computer card that connects between the touch sensor and the computer. It takes information from the touch sensor and translates it into information that the processor can interpret.
- Software Driver: The driver is a software update for the processor system allowing for the touch screen and computer to work together. It tells the computer's operating system how to interpret the touch event information that is sent from the controller.
