Apparatus and method for inputting alphabet characters on keypad

Claim Score by NHIP

Read claim 19, the broadest

Abstract

The invention is to efficiently input characters on a keypad and, more particularly, to input various symbols by using the hiding control processing method, thereby maintaining a simple arrangement of the keypad. Furthermore, the present invention produces simple codes using the relation between characters allocated to the keypad and numerals, implements the short-cut input method using the simple codes, and enters target characters and words or phrases with a small number of strokes using the concurrent input method. With a switching server for interpreting simple codes, the user can input simple codes even when the third server requests words or phrases other than simple codes, and the switching server interprets simple codes input by the user and sends the words or phrases corresponding to the simple codes to the third server, which does not store the simple codes and the words or phrases corresponding to the simple codes.

33 claims: 19 independent, 14 dependent

  1. 1
    A method for entering characters from a keypad, which uses a repeat selection method, the method comprising:determining a successive stroke delay time (a time for first recognizing two strokes of a button as a second character) differently from a discrete stroke delay time (a time for first recognizing two strokes of a button as two inputs of a first character).
  2. 2
    A method for entering characters from a keypad, comprising:grouping the characters into groups each assigned to a button, the characters of a corresponding group comprising a representative character and its succession characters;selecting a “next control” by pressing a control button;and entering the succession characters through a combination of the previous character and the “next control”.
  3. 3
    A method for entering characters from a keypad, which uses a control processing method, the method comprising:regarding a control as nonexistent if the control to be associated with a representative character is meaningless (wherein a combination of the selected control and the representative character does not form a meaningful character).
  4. 4
    A method for entering characters from a keypad, which uses a control processing method, the method comprising:regarding numerals and English alphabet assigned to each button as succession characters, and control processing the succession characters.
  5. 5
    A method for entering characters from a keypad, which is to input Arabic characters, the method comprising:grouping characters having meanings of numerals into nine groups of about three characters, the nine groups comprising a first group of characters having the meaning of a numeral starting with 1 on the keypad (i.e., 1, 10, 100 or 1, 10, 100, 1000), a second group of characters having the meaning of a numeral starting with 2 on the keypad (i.e., 2, 20, 200), and third to ninth groups of characters having the meaning of a numeral starting with 3 to 9 on the keypad, respectively;assigning the individual groups to buttons [1] to [9], respectively;designating characters of a unit as representative characters in each of the nine groups, the characters of a unit comprising 1-unit characters meaning 1, 2, 3, . . . , or 9, 10-unit characters meaning 10, 20, 30, . . . , or 90, and 100-unit characters meaning 100, 200, 300, . . . , or 900;and regarding the characters of the other units as succession characters of the representative character and control processing succession characters.
  6. 6
    A method for entering characters from a keypad, which is to input Korean characters, the method comprising:grouping ten basic consonants and ten basic vowels into ten pairs of a basic consonant and a basic vowel;selecting a consonant with one stroke and a vowel with two strokes;assigning an aspirated consonant control to either a button [*] or a button [#], and a tense consonant control to a button not designated for the aspirated consonant control;and control processing aspirated consonants and tense consonants.
  7. 7
    A method for entering characters from a keypad, in which consonants and vowels are grouped into pairs of a consonant and a vowel and are assigned to each button, and a consonant is selected with one stroke of the button, a vowel being selected with two strokes of the button, the method comprising:grouping consonants and vowels so as to entirely minimize the frequencies of vowel-consonant transition (vowel-consonant coupling in a syllable comprising “consonant+vowel+consonant”) and consonant-vowel transition (consonant-vowel coupling in a syllable comprising “consonant+vowel”), which utmost causes ambiguity.
  8. 8
    A method for entering characters from a keypad, which is to input Korean characters by selecting characters or controls on the keypad using a repeat selection method, the method comprising:optionally assigning nine of ten basic consonants other than one destitute of an aspirated consonant or a tense consonant to numeral buttons [1] to [9], respectively;optionally assigning three vowel elements “—”, “.” and “ ” to the three other buttons [*], [0] and [#];and arranging each of the basic consonants and vowel elements to be selected with one stroke of the corresponding button.
  9. 14
    A method for entering characters from a keypad, which is to input characters through the keypad, the method comprising:looking up correct words in an index provided on a client or a server in the unit of words (i.e., at the end of each word) when ambiguity occurs while inputting a full code.
  10. 16
    A method for using a simple code on a keypad, the method comprising:designating a corresponding numeral on the keypad as the simple code, the numeral being associated with a consonant included in a given word or phrase.
  11. 17
    A method for using a simple code on a keypad, the method comprising:designating a corresponding numeral on a keypad as the simple code, the numeral being associated with initial consonants or vowels of syllables in a given word or phrase.
  12. 18
    A method for using a simple code on a keypad, the method comprising:designating a corresponding numeral on a keypad as the simple code, the numeral being associated with initial characters of words in a given phrase.
  13. 19
    Broadest claimClaim Score 98, very broad(NHIP)The method as claimed in claims 16 , the method comprising:marking in bold the characters associated with the simple code in the word or phrase.
  14. 21
    The method as claimed in claims 16 , the method comprising:a client or a server searching characters corresponding to an input value of the simple code and providing them to the user, thereby making it possible to input a target word or phrase.
  15. 27
    A method for entering characters from a keypad, which is to input various symbols through the keypad, the method comprising:dividing the symbols into symbol groups;assigning the meaning of a specific symbol group to a button on the keypad (i.e, associating a specific symbol group with a button on the keypad;arranging a plurality of symbol controls (i.e., symbol 1, symbol 2, . . . ) on a button on the keypad;selecting the symbol controls by using a repeat selection method;and inputting the symbols of the specific symbol group through a combination of the button, endowed with the meaning of the specific symbol group, and the symbol controls.
  16. 28
    A method for entering characters from a keypad, which is to input characters with a terminal having up/down/right/left move buttons, the method comprising:using the up/down/right/left move buttons, not frequently used in a character input mode, as various control buttons.
  17. 30
    A method for entering characters from a keypad, which is to input characters on the keypad by using various control processing methods, the method comprising:simplifying the functions of control buttons into icons and displaying the icons on a screen (liquid crystal display).
