Touch Screen Integration-Image

TOUCH SCREENS

Touch screens are often used as an alternative—or in addition to—more traditional human-machine interface technologies, such as a membrane switch or keyboard. The use of a touch screen allows the keypad to be reconfigured as desired to suit the application. Because of their intuitive nature, touch screens are often used in applications where the user cannot be trained to interface with the device. Kiosks and point-of-sale devices exemplify these applications. Also read: Touch Feedback for Touch Screens
