A concept keyboard is a flat board which contains a grid of switches. Each switch can be
programmed to do whatever you want. An overlay
image is placed on top of the grid so that the user can tell what pressing on different
areas of the keyboard (switches) will do.
Example uses of concept keyboards include :
- Piano : The overlay image could be of a piano
keyboard. Pressing on the piano keys will cause the computer to play the note that is pressed.
- Country Information : The overlay image could be a map of
an area of the world. Pressing on a country would cause the computer to display information about that
country on a monitor.
- Tills in restaurants/pubs : The overlay
contains a list of all of the meals that can be purchased. Instead of typing in prices
the waiter simply presses on the appropriate meal name on the keyboard when a meal is
purchased.
Concept keyboards are particularly useful for users such as children who would find using a
QWERTY keyboard difficult and in locations where an ordinary keyboard might be damaged,
e.g. by spillage or dust.
