Definitions

  • the present invention relates to a method of encoding alphabetic characters for a chord keyboard. More specifically, the present invention relates to a method of encoding alphabetic characters for a chord keyboard and generating electrical signals identifying the alphabetic characters to a word processor or the like.
  • Chord keyboards are known in the art and generally include at least five character keys, one for the thumb and each of the four fingers of a single hand of an operator.
  • chord keyboards are designed so that keys may be actuated either individually or in chord combinations to selectively generate the 26 letters of the English alphabet.
  • chord keyboards In order to make these chord keyboards practical, the codes or conventions for generating the alpha characters should be easy to learn and remember. Chord keyboards of the type described are disclosed in U.S. Patents 4,443,789 and
  • a primary object of the present invention is to provide an improved method for encoding the alphabetic characters of a chord keyboard which is learnable and usable. It is a further object of the present invention to provide a method of encoding a chord keyboard which facilitates fast one-hand typing speed.
  • a method of encoding alphabetic characters and inputting electrical signals defining those characters to a computer comprising the steps of: 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; 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; designating combinations of alpha input keys to represent each consonant letter of the alphabet; and 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 computer.
  • chord combinations designated to represent a consonant in a preferred embodiment include an alpha input key designated to represent the last vowel preceding that consonant in alphabetical order.
  • successive consonants moving in alphabetical order are defined by a chord combination which includes the addition of the next successive alpha key moving seriatim from the thumb to the little finger (pinky) of the typist's hand, whereby the sequential movement of the operator's fingers functions as a mnemonic to the typist for the chord combinations.
  • Fig. 1 is a schematic block diagram illustrating a chord keyboard and a standard keyboard coupled to a microprocessor in order to illustrate the hardware of the system in which the method of the present invention would be utilized;
  • Fig. 2 is a top plan view of a one-handed, five key chord keyboard usable in the system of Fig. 1.
  • chord keyboard 10 which could be of the type described in the aforementioned Endfield and Heusinkveld patents.
  • the chord keyboard is utilized to generate alphabetic character signals and input the signals to a microprocessor 14 in response to individual or chord combination key actuations.
  • the chord keyboard 10 may be used as a supplement to a standard keyboard 12 or it may be used in place of the standard keyboard 12 as desired.
  • Microprocessor 14 would in most instances be part of a word processing system and would be coupled to peripheral components such as monitors and printers through an input/output bus 16.
  • a chord keyboard 10 includes 5 alpha input keys dedicated for actuation by the thumb, index, middle, ring and pinky fingers, respectively.
  • the thumb is still the number 1 key and the rest of the fingers follow in succession in mirror image.
  • these keys are numbered 1 to 5, respectively, so that the thumb is 1, the index finger is 2, the middle finger is 3, the ring finger is 4, and the pinky or little finger is 5.
  • the method of the present invention relates in part to Applicants discovery that if each of the individual keys of the chord keyboard 10 are designated to correspond, respectively, to the 5 vowels, ''a", “e", “i”, “o”, “u” that the key associations with the vowels and in fact all associated consonants of the English alphabet are easier to remember. That is key “l” corresponds to the vowel • ⁇ a"; key “2” corresponds to the vowel "e”; key “3 n corresponds to the vowel "i 1 "; key “4" 1 corresponds to the vowel "o''; and key "5" corresponds to the vowel "u”. This is easily and readily remembered because the five vowels correspond to each of the five fingers of the operator's hand. Therefore, the feel associated with respect to fingers of the hand, as they depress keys on a keyboard, actually assist in the memory of these conventions.
  • vowels of course are the most often used letters in the typing of words. Therefore, it is important to have a simple method of remembering the vowels, and to associate each vowel with one of the five keys provides this simplicity. Furthermore, actuation of the vowels is the simplest of any of the actuations because only a single key actuation is required for generating an electrical signal representative of a vowel.
  • the designation of the vowels as corresponding to the respective five keys of the keyboard is an important aspect of the present invention and these vowels can be used as landmarks or roots for determining the chords (key actuation combinations) which represent the remaining consonants of the alphabet.
  • chord combination designated to represent a consonant is more easily learnable if an alpha input key designated to represent the last vowel preceding that consonant in alphabetical order is included in the chord combination. For example, referring to Fig. 2 if key "1" associated with the thumb is the vowel "a”, consonants B,C,D are generated by chord combination key actuations as follows:
  • chords relating to consonants B, C, D that successive consonants moving in alphabetical order are 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.
  • this arrangement and the rolling motion of one's fingers from left to right functions as a mnemonic to the operator of the chord combinations.
  • the encoding method of the present invention enables relatively fast typing speeds for a one-handed, five key keyboard which is easy to use, learn and memorize.

Abstract

Un procédé de codage des caractères de l'alphabet et d'introduction de signaux électriques définissant ces caractères dans un ordinateur (14) comprend un clavier (10) composé de cinq touches (1-5) individuelles d'introduction de lettres de l'alphabet, une touche d'introduction se trouvant, en fonctionnement, associée au pouce de l'opérateur et les autres touches (2-5) étant chacune réservée pour chaque doigt de la main de l'opérateur. Chacune des touches d'introduction (1-5) alpha représentant une des cinq voyelles. Par conséquent, lorsque ces touches (1-5) sont actionnées individuellement, elles génèrent des signaux électriques correspondant aux voyelles. Les consonnes correspondent aux combinaisons s'effectuant par actionnement simultané des touches. Des signaux électriques uniques sont générés en réponse à l'actionnement d'une ou plusieurs touche(s) alpha (1-5) afin d'introduire sélectivement les signaux électriques définissant les caractères de l'alphabet dans l'ordinateur (14).
