Concept Keyboard

This is a keyboard-like device with a number of pictures instead of the usual keys. The user indicates input by pressing one of the pictures. It is used as an input device for young children in Computer Based Learning systems and it is sometimes used in cafés and pubs where there is a computerised till. A feature of this device is the capability to change the overlay to provide a different set of pictures. This is particularly useful in computer based learning as a single keyboard can then be used with a variety of overlays.

Concept keypads are faster but very limited They are used in shops for example balances where the goods are pictured. They are also used in pubs where the drink is named.
