Shouding Touch Screen Controllers
Touch screen controllers are devices that are used to interact with a touch screen display. They provide a tactile interface for the user to control what is seen on the screen, allowing a simplified way to interact with the device. Some controllers require physical contact with the screen in order to activate them, while others respond to finger proximity, providing a more natural way of interacting with a display. Touch screen controllers can be attached to a wall or a table, depending on the specific application. Many touch screen controllers now feature backlit keys, haptic feedback and voice input to provide a more intuitive user experience.
