A type of keyboard used a lot in the service industries. Each key on the keyboard can be programmed with a specific function. For example, a Concept Keyboard in a pub could have selected keys programmed to add in the price of a particular drink when pressed: thus the operator need only press a key indicating the price of a particular pint of beer, rather than using several keys to input exact price.

A Concept Keyboard is a flat, touch sensitive board, usually A3 or A4 in size, which you can plug into your computer and use as an addition to the QWERTY keyboard. A paper overlay is placed onto the board and the user presses the overlay to activate the board. Normally used for special purposes, eg. to help a disabled person, someone with learning difficulties or a young child.
