Method of encoding alphabetic characters for a chord keyboard

A method of inputting electrical signals relating to alphabetic character data to a computer comprising the steps of:

• a) providing a keyboard having five individual alpha input keys, one alpha input key being operatively associated with an operator's thumb and the remaining keys each being dedicated for operation by one finger of the operator's hand, said keys being actuable either individually or in chord combinations for encoding said alphabetic characters and inputting said signals to the computer;
• b) designating each alpha input key to represent one of the five vowels "a", "e", "i", "o", "u" when actuated individually without actuation of any other alpha keys in combination therewith, the designation of the alpha input keys being such that in an operative position of the operator's hand the thumb activates the "a" or first key, the index finger actuates the "e" or second key, the middle finger activates the "i" or third key, the ring finger activates the "o" or fourth key and the pinky activates the "u" or fifth key;
• c) designating cord combinations of the same five alpha input keys to represent each consonant letter of the alphabet, said chord combinations designated to represent a consonant including an alpha input key representing the last vowel preceding that consonant in alphabetical order, successive consonants moving in alphabetical order being defined by a chord combination which includes the addition of the next successive alpha key moving seriatim from the thumb to the little finger of the operator's hand, whereby the sequential movement of the operator's fingers functions as a memory aid to the operator of the chord combinations;
• and
• d) generating unique electrical signals in response to the actuation of one or more of said alpha keys to selectively input the electrical signals defining the alphabetic characters to the word processor.

• b) designating each alpha input key to represent one of the five vowels "a", "e", "i", "o", "u" when actuated individually without actuation of any other alpha keys in combination therewith, the designation of the alpha input keys being such that in an operative position of the operator's hand the thumb activates the "a" or first key, the index finger actuates the "e" or second key, the middle finger activates the "i" or third key, the ring finger activates the "o" or fourth key and the pinky activates the "u" or fifth key and designating chord combinations of alpha input keys to represent each consonant letter of the alphabet, whereby electrical signals defining letters A to K are generated by individual or combined actuation of said keys "1" to "5" as follows,
• A=1
• B=1,2
• C=1,2,3
• D=1,2,3,4
• E=2
• F=2,3
• G=2,3,4
• H=2,3,4,5
• I=3
• J=3,4
• K=3,4,5
• c) designating individual or combined actuations of keys "1" to "5" to represent the remaining letters of the alphabet as follows:
• L=1,3
• M=1,3,4
• N=1,3,4,5
• O=4
• P=1,4
• Q=1,2,4
• R=1,2,4,5
• S=2,4,5
• T=4,5
• U=5
• V=1,5
• W=1,2,5
• X=1,2,3,5
• Y=2,3,5
• Z=3,5;
• and
• d) generating unique electrical signals in response to the foregoing individual or combined actuations of said alpha keys to selectively input the electrical signals defining the alphabetic characters to a computer.
