Method of generating symbols from a chording keyboard

A method of generating symbols using a chording keyboard comprising n, at least two-position, keys;

• wherein the keyboard comprises at least 2^n possible keyboard chords;
• comprising the steps:
• a) creating a chord table containing at least 2^n lines, one line for each possible chord;
• b) associating one symbol, from a pre-defined first symbol set consisting of S unique symbols, with each line in the chord table;
• c) accepting a chord from the chording keyboard;
• d) outputting the symbol associated with the chord;
• e) repeating from step c);
• wherein n is at least 4 and less than 10;
• and
• wherein when the keyboard generates any first chord in the set of 2^n consisting of a first depressed subset of keys and the keyboard then generates immediately following any second chord in the set of 2^n chords comprising a second, different, depressed subset of the n keys,
• wherein the transition from the first chord to the second chord is free of any required key transitions other that those required to transition directly from the first depressed subset of n keys to the second depressed subset of n keys;
• wherein the chord table comprises the following partial chord table:
• Symbol
• Chord
• Space
• X O O O O
• Letter E
• X X X X O
• Letter T
• X X O O O
• Letter A
• O X O O X
• Letter O
• X X O O X
• Letter I
• X O X X O
• wherein the order of the keys for the chords shown above is, left to right, thumb, index finger, middle finger, ring finger, pinky finger, and wherein X means the corresponding key depressed and O means the corresponding key released.
