Morse Keyboard

[Morse Keyboard is hear.]
This is a personal computer input device intended for the peoples with disabilities who can't use a standard keyboard ( muscular dystrophies with limited mobility of fingers and cerebral palsies incapable of sophisticated movements).

The new device applies Morse codes for input of characters. Each character is expressed by a combination of dot and dashes(e.g. "¥-" for "a") and is entered by pressing the "input" key. Three keys minimum are required for input of all characters. The number of keys and their types can be modified according to the disabilities.

There are two type,type M(memorized-based ) and type D(display-based).
