Touch screens

Touch screens are sensitive display screens that enable the computer to react to the touch of a finger or stylus. These can aid learners who may prefer to make simple selections on screen, rather than use a keyboard.

Touch screens are excellent access devices for children with learning difficulties and, in some situations, for children with physical difficulties. The most effective touch screens are those where the touch-sensitive surface is built into the monitor, but touch screens are also available to fit over existing displays.

Touch screens have been used as assistive technology for many years, providing an alternative to standard input devices for users who need access to standard applications. Specially designed applications have also been developed specifically for touch screen use. These applications typically include large icons and a simple intuitive design layout.
