Morse Code is inputted by varying the timing of the press of a single key, e.g., short press, pause, long press
Morse Code is variable length, giving it much less entropy than that of ASCII, i.e., it takes 1 key press to input an E in Morse Code, but 7 (assuming 7-BIT) in ASCII.
But, practically speaking, American Morse Code defines only 36 characters (26 letters, 10 digits), which obviously makes it not such a good code for a modern computer input device.
A more efficient “Binary Keyboard” would create a new variable length code based on frequencies of symbols, which could cut down significantly on keypresses.
How does this differ from Morse code? :-)
2 significant ways:
