`ABSTRACI‘
`
`A method and apparatus for entering data into a com-
`puter including an abbreviated keyboard wherein each
`key represents a plurality of characters. Depression of a
`key of the keyboard causes the generation and transmis-
`sion of a first electronic signal to a computer. The com-
`puter receives the signal and according to a predeter-
`mined algorithm, generates a best guess of which one of
`the plurality of alphanumeric characters represented by
`the key and signal sent to the computer is desired to be
`ultimately entered into the computer. A second elec-
`tronic signal is generated by the computer and transmit-
`ted to a display to cause the display to indicate the
`guess. By subsequent stroke or strokes of the keyboard,
`the guess is either selected if correct, or if incorrect
`changed until the correct alphanumeric character is
`guessed.
`
`The computer programmed with the algorithm for
`making the guesses may be remote to the keyboard or
`contain within the keyboard such as by the incorpora-
`tion of an appropriate microchip. If remote, the com-
`puter may be the same computer to which data will be
`transferred or may be an associated apparatus. Such
`associated apparatus may include display means for
`displaying the guess.
`
`In one embodiment the keyboard and display means are
`integral with a telephone. A secondary display means is
`provided to show an accumulation of characters previ-
`ously transmitted, or accumulated in buffer for subse-
`quent transmission.

`COMPUTER DATA ENTRY METHOD AND
`APPARATUS
`
`BACKGROUND
`
`The present invention relates generally to a method
`and apparatus for entry of data into a computer. More
`particularly, the present invention relates to the entry of
`data into a computer with an abbreviated keyboard
`using two or more strokes to enter a single character
`into the computer.
`A number of apparatus are known for the entry of
`data into a computer with an abbreviated keyboard.
`Morely, et al., U.S. Pat. No. 4,005,388 disclosed a hand-
`held system having a keyboard, a portion of which is
`similar to a telephone dialing system. Each of the keys
`in the keyboard have several alphanumeric_ characters.
`By actuating one of the keys on the keyboard and then
`actuating a set of keys on the side of the keyboard, one
`of the characters of each key can be selected for input
`into the computer.
`-
`U.S. Pat. No. 3,772,597 to Stover discloses a nine-key
`keyboard in which each key can be used for entering
`any one of four different letters. Each of the keys is set
`up as a rocker key so that when pushing the key to any
`one if its sides a different letter will be activated.
`U.S. Pat. No. 3,967,273 to Knowlton discloses a key-
`board on a telephone in which each key has a plurality
`of letters, numbers or other symbols. By first pressing
`one of the keys on the keyboard and then pressing a
`second key which indicates a particular location of the
`particular character on the first key pressed, a particular
`character can be entered into the computer.
`U.S. Pat. No. 4,029,915 to Ogima and U.S. Pat. No.
`4,449,839 to Bleuer disclose keyboards having a set of
`rocker keys in which each rocker key can be used for
`entering any one of several different characters into a
`computer.
`
`U.S. Pat. No. 4,385,291 to Piguet discloses a system
`for entering information into a small computer within a
`watch. In this system a range of digits are displayed in
`display window 2. Key 7 can select a particular range to
`be displayed and a larger segment of the range is se-
`lected by a key 5 and the particular letter within the
`range is selected by key 6. In this manner, various char-
`acters can be entered into the computer utilizing a mini-
`mum number of keys.
`U.S. Pat. Nos. 4,486,741 to Nozawa, et al., 4,481,508
`to Kamei, et al., 4,340,887 to Dias II, 4,202,038 to Peter-
`sson, 4,201,489 to Zapp, and 4,124,843 to Bramson, et al.
`that illustrate additional keyboard art.
`
`SUMMARY OF THE INVENTION
`
`The present invention involves an abbreviated key-
`board wherein each key represents a plurality of char-
`acters. Depression of a key of the keyboard causes the
`generation and transmission of a first electronic signal
`to a computer. The computer receives the signal and,
`according to a predetermined algorithm, generates a
`best guess of which one of the plurality of alphanumeric
`characters represented by the key and the signal sent to
`the computer is desired to be ultimately entered into the
`keyboard. A second electronic signal is generated by
`the computer and transmitted to a display to cause the
`display to indicate the best guess. By subsequent stroke
`or strokes of the keyboard, the guess is either selected if

`
`correct, or, if incorrect, changed until the correct alpha-
`numeric character is guessed.
`The computer programmed with the algorithm for
`making the guesses may be remote to the keyboard or
`contained within the keyboard such as by the incorpo-
`ration of an appropriate microchip. If remote, the com-
`puter may be the same computer to which data will be
`transferred or may be an associated apparatus. Such
`associated apparatus may include display means for
`displaying the guess. In one embodiment the keyboard
`and display means are integral with a telephone. A
`secondary display means is provided to show a string of
`characters previously transmitted, or accumlated in
`buffer for subsequent transmission.
`In another embodiment, a monogram pattern is uti-
`lized wherein each key of the keyboard corresponds to
`one portion of the monogram pattern. The mosaic pat-
`tern is displayed on the keyboard or associated appara-
`tus. Depression of the key will change the state of the
`corresponding portion of the displayed monogram pat-
`tern between illuminated and not illuminated. The com-
`puter or microchip in communication with the key-
`board receives the signal and determines one or more
`best guesses of the desired character according to a
`predetermined algorithm. These best guesses are dis-
`played on a display provided on the keyboard, or alter-
`natively, on associated apparatus. Subsequent strokes of
`the keyboard select one of the best guesses or change
`the mosaic pattern to initiate the generation of a second
`round of best guesses.
`The present invention allows communication with
`and entry of data into a computer from a standard tele-
`phone utilizing a standard telephone keyboard. The
`computer is connected to a phone line and processes the
`signals generated by the standard twelve telephone
`keys. Return signals from the computer are received by
`auxiliary apparatus provided in line to accept and pro-
`cess the signals between the keyboard and the com-
`puter. Alternatively, the computer may generate second
`electronic signals which cause audible enunciations
`through the phone handset which are simulative of
`human speech, prerecorded human speech, or at least
`human understandable code such as Morse code.
`An object of the present invention is a method of
`entering data into a computer.
`Another object of the present invention is a method
`of entering data into a computer wherein an operater
`causes a first signal which corresponds to a plurality of
`characters to be transmitted to the computer, the com-
`puter generates a second signal corresponding to a best
`guess of which of the plurality of characters is intended
`and the operator causes a third signal to be transmitted
`to the computer to initiate the transmission of the
`guessed character or the generation of a second guess.
`A further object of the present invention is an appara-
`tus for entering data into a computer.
`A still further object of the present invention is an
`apparatus for entering data into a computer wherein an
`abbreviated keyboard is used.
`Yet another object of the present invention is an ap-
`paratus having the foregoing advantage and which uses
`a standard telephone keyboard.
`Other objects and advantages of the present invention
`will be readily apparent from the following description
`and drawings which illustrate the preferred embodi-
`ments of the present invention.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`Refer now to FIG. 1, there being shown a preferred
`embodiment of a telephone incorporating a keyboard
`according to the present invention and generally desig-
`nated by reference numeral 10. Telephone 10 includes a
`standard size housing 34 and keyboard 18. Standard
`telephone line 30 provides a communication access line
`to a computer to which data is to be transferred. Key-
`board 18 includes the standard twelve telephone but-
`tons with character designations added where space
`permits such that each key carries four alphanumeric
`characters. Keyboard 18 includes, in addition, control
`buttons 17 and 19 and character buttons 32 and 33.
`Displays 11, 12, 13, and 14 are one character alphanu-
`- meric displays for displaying the best guess generated
`by the programmed algorithm. Display 15 is provided
`to display a symbol or a letter to indicate status such as
`whether the keyboard is in upper case, upper caselock,
`or control mode. Display 16 is a running input/output
`display for displaying an accumulation of characters
`that have been previously transmitted across line 30, or
`stored in a provided buffer for later transmission.
`The operation of the keyboard is a multistroke pro-
`cess. The person operating the keyboard first presses
`one of the keys, each representing four alphanumeric
`. characters. These characters are displayed in displays
`11, 12, 13 and 14. The computer receives the first signal
`generated by the depression of the key, recognizes the
`first signal and according to a predetermined algoritm,
`generates a best guess of which which one of the four
`» alphanumeric characters represented by the key and the
`first signal is desired to be ultimately entered into the
`computer. A second electric signal is generated by the
`computer and transmitted to display 11 to cause display
`of the best guess. The remaining characters are dis-
`played in displays 12, 13 and 14in order of their likeli-
`hood of being chosen, according to the algorithm, as the
`character desired to be ultimately entered into the com-
`puter.
`If the guess diplayed by display 11 is correct, control
`key 19 is pressed and the character is stored in buffer
`and displayed at the end of a series of previous choices
`by display 16. Pressing the control key a second time at
`this point, causes the string of alphanumeric characters
`displayed by display 16 to be transmitted over line 30 to
`the computer being in phone-line communication with
`keyboard/telephone 10. Pressing the control key a. third
`time will cause the keyboard to shift into regular tele-
`phone mode.
`If‘, on the other hand, the guess displayed by display
`11 is incorrect, the original alphanumeric key is pushed
`again and a new guess is generated. In this embodiment,
`pressing the alphanumeric character key a second time
`
`4
`causes the guesses to shift to the left such that, for exam-
`ple, the alphanumeric character displayed in display 12
`will be shifted to display 11. If the new guess is correct,
`the control key 19 is pressed as indicated above.
`'
`The shift key 17 functions to shift between upper and
`lower case.
`One algorithm suitable for use with the present inven-
`tion is as follows:
`If the keystroke generating a first electric signal rep-
`resents the beginning of a word,
`the first consonant
`represented on the key is chosen as the best guess. Ap-
`propriate second electronic signals are generated and
`transmitted to the displays. If this guess is correct, a
`designated key, such as the control key is pressed gener-
`ating an electric signal recognized by the computer to
`indicate that the data should be transmitted to the com-
`puter or buffer storage. However, if this guess is not
`correct, the originally pressed alphanumeric character
`key is pressed again and the algorithm selects the next
`consonant. Again, if this is not correct the key is pressed
`again and the computer goes through the consonants in
`this manner and then the vowels and then the numerals
`- or other characters displayed on the particular key. As
`each key only represents a small number of characters,
`four to six characters generally at the most, this process
`would be quick.
`The algorithm could be expanded such that if the
`previous character entered into the computer was a
`consonant the first guess would be a vowel represented
`on the key and, vice-versa, if the previous character was
`a vowel the next letter would be a consonant. A further
`amplification of this algorithm could be that if the previ-
`ous character was not a letter but, rather, a number,
`then the first guess would also be a number. Many other
`algorithms and expansions of the foregoing algorithm
`are possible. For example, the probability of a letter
`appearing after another in the English language could
`be programmed into the microchip to fine tune the best
`guess.
`The algorithm could also be expanded such that not
`only the previous letter but the previous string of letters
`or previous word or words would be used to improve
`the guess by the computer.
`Moreover, the algorithm could guess not only a sin-
`gle character but one or more characters or one or more
`words, as well as punctuation, based on previous
`entries.
`Refer now to FIG. 2 illustrating an alternate embodi-
`ment of the present invention, wherein a standard tele-
`phone 54 is shown having overlay 19 laid over the
`telephone keyboard. Controller 58 is connected in the
`telephone line 60, 62 to provide display and control
`capabilty to the user. Controller 58 includes two dis-
`plays, display 64 which illustrates a monogram pattern
`and display 70 which illustrates the best guesses gener-
`ated by the computer. The computer may be integral to
`controller 58, in the form of a microchip, or may be in
`communication with the keyboard through controller
`58 through phoneline 62. Controller 58 also includes a
`control button 72 and a shift button 74.
`Refer now to FIG. 3 which illustrates a more detailed
`view of the abbreviated keyboard of FIG. 2 incorporat-
`ing a monogram display pattern. An overlay 19 may be
`placed over a standard keyboard as represented in FIG.
`3. Each key of the keyboard corresponds to one of the
`bars of the monogram pattern as shown.
`FIG. 4 illustrates the mosaic pattern showing selected
`bars lit to form the character 8. The keyboard controls

`the display by causing the bar to change state, to be-
`come lit or unlit, when the corresponding key is de-
`pressed. Keys 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 20, and
`31 correspond to monogram bars 41, 42, 43, 44, 45, 46,
`47, 48, 49, 50, 40 and 51, respectively, and the corre-
`sponding bar indications on overlay 19 are 41’, 42’, 43’,
`44', 45', 46', 47’, 48', 49’, 50', 40’ and 51’, respectively.
`In operation, when a character is to be entered into
`the computer, first the computer is accessed through the
`telephone line. Secondly, the monogram display 64 will
`display a predetermined first guess as illustrated. In the
`preferred embodiment this is the character 8. By strok-
`ing one of the keys, a signal is sent to controller 58.
`Controller 58 senses the signal and changes the state of
`the corresponding bar in the display 64. Accordingly, if
`a predetermined first guess is the numeral 8 and key 1 is
`stroked, then the display will appear as in FIG. 5. The
`microchip, according to a predetermine algorithm, will
`sense the change in bar 41 and generate one or more
`20
`guesses of the character which is ultimately desired to —
`be transmitted to the computer. Such an algorithm may
`pick the characters 11, m, x and asterisk. If the first guess
`is correct, an appropriate button on controller 58 can be
`depressed and the signal sent.
`Alternatively, the 3 button could be pressed which
`would change the display to appear as in FIG. 6. The
`computer would then improve the guess and eliminate
`the choice of 11. Once the choices were narrowed to one
`in this manner, then the signal would automatically be
`sent. This would eliminate the need for any control keys
`on the controller 58 itself.

`
`A further alternate embodiment could incorporate a
`means of display that will be audible as well as, or rather
`than, visual. For example,
`the computer could be
`adapted to generate a second signal that included at
`least a portion that would generate a human voice simu-
`lation in the telephone handset coresponding to the
`spoken sound of the best guess character. Alternatively,
`this audible display could be morse code or other audi-
`bly recognizable display other than spoken human
`voice.
`
`As discribed above, the embodiment of FIG. 1 could
`be modified to utilize a separate rather than integral
`controller such as controller 58 of FIG. 2. Moreover,
`the embodiment of FIG. 2 could be modified to include
`integral displays on the keyboard of the monogram
`pattern and best guesses.
`A further embodiment of the present invention could
`utilize a controller such as controller 58 of FIG. 2,
`except the controller could be adapted to accept the
`telephone handset, such as a MODEM does, and to
`recognize and transmit through the telephone handset.
`This adaptation would be particularly useful with tele-
`phones having non-disconnectable phone line connec-
`tions, such as in public pay phones.
`In another alternate embodiment, selection keys may
`be provided corresponding to all of the characters dis-
`played, or all of the characters displayed except the best
`guess. If one of the selection keys is pressed, the corre-
`sponding character is entered into the computer. How-
`ever,
`if none of the selection keys are pressed, but
`rather, a second character key is pressed, then the best
`guess is automatically entered into the computer and a
`new best guess corresponding to the second character
`key is generated. In this way, the first character having
`been guessed correctly, is entered into the computer
`with, effectively only one stroke.

`board means and in electric communication with said
`keyboard means and the computer.
`15. An apparatus as in claim 14 wherein said key-
`board means is a standard telephone.
`16. An apparatus as in claim 1 wherein said prediction
`algorithm predicts a character as a function of the oc-
`currence probability of said character and as a function
`of said previously entered data.
`17. An apparatus as in claim 16 wherein said predic-
`tion algorithm predicts a sequence of characters or-
`dered in accordance with descending probability of
`occurrence thereof.
`18. An apparatus as in claim 17 wherein said display-
`ing means displays a sequence of characters ordered in
`accordance with descending probability of character
`occurrence.
`
`19. A method of entering data into a computer com-
`prising the steps of:
`(a) Providing a first signal generating means for selec-
`tively generating a first electric signal, storing pre-
`viously entered data using memory storage means,
`providing a processing means for receiving said
`first electric signal and for generating, according to
`a pre-determined prediction algorithm, a plurality
`of second electric signals corresponding to one or
`more alphanumeric characters in response to both
`the first electric signal and to said previously en-
`
`8
`tered data, providing display means for receiving
`said second electric signals and, responsive thereto,
`displaying said alphanumeric characters, and, pro-
`viding transmission means for selectively transmit-
`ting a third electric signal corresponding to one or
`more of said alphanumeric characters to the com-
`puter;
`(b) Operating said first signal generating means to
`send said first signal and to cause the generation of
`said second electric signal by said processing means
`and said display means;
`(c) Operating said transmission means to transmit a
`selected one or more of said alphanumeric charac-
`ters to the computer.
`20. A keyboard apparatus comprising: keyboard
`means for selectively generating a plurality of first elec-
`tric signals; memory means for storing previously en-
`tered data; processing means for receiving said first
`electric signals and, according to a pre-determined pre-
`diction probability algorithm, generating a plurality of
`second electric signals for corresponding to one or
`more alphanumeric characters predicted in response
`both to said generating means and to said previously
`entered data; and, displaying means for receiving said
`second signals and responsive thereto displaying said
`corresponding alphanumeric characters.
