[Task management number: 2006-X-001-03, Task name: Real-time postal logistics element technology development].

When inputting a standardized Korean character string such as an address of a mail, a double type keyboard having separate Korean characters and numbers is used. However, the two-bolt type keyboard does not reflect the characteristics of the Korean address of the mail.

On the other hand, in order to efficiently input a standardized Korean character string, a method of showing the character strings closest to the input character string as a candidate has been proposed. This method selects a candidate by using a direction key, a mouse, or the like, or assigning a sequential number to the candidate and inputting the candidate number. In this case, the method of selecting a candidate using a direction key or a mouse requires repetitive input of a direction key or moves a scroll when a desired character string is in a lower candidate. In addition, the method of assigning a number to a candidate and inputting a candidate number has a hassle of switching to a candidate selection mode using a special key or the like in order to distinguish between a character string to be input or a number for selecting a candidate.

The technical problem to be solved by the present invention is to provide an input device that can easily input a standardized Hangul string, such as an address.

1 is a diagram illustrating an input device according to an exemplary embodiment of the present invention.

Referring to FIG. 1, in the input device 10 according to an exemplary embodiment of the present invention, consonants and vowels are allocated to 28 regions except for the edge region of each row among 34 regions consisting of three rows. Hangeul consists of 19 consonants and 14 vowels. At this time, 14 consonant keys except for 5 consonants (ㅃ, ㄸ, ㅌ, ㅌ, ㄲ) are assigned to the left 14 of the 28 areas, 12 vowels are assigned to the right 14 areas. At this time, consonants are assigned to the consonants and vowels in the left 14 regions and the right 14 regions, respectively, in the same manner as the consonants and vowels are allocated in the two-bulk Korean keyboard.

Specifically, the left 5 of the 10 areas except the edge of the first row are assigned 'ㅂ', 'ㅈ', 'ㄷ', 'ㄱ' and 'ㅅ' in order from the left, and the right 5 areas Are assigned 'ㅔ', 'ㅐ', 'ㅑ', 'ㅕ' and 'ㅛ' in order from the right. In this case, all five consonants (ㅃ, ㄸ, ㅌ, ㅌ, ㄲ) are inputted by combining the corresponding consonant and 'shift' key, and 'ㅒ' and 'ㅖ' of the double vowels are respectively 'ㅐ' And the combination of 'ㅔ' and 'shift' key.

Of the nine areas except the edge of the second row, the left five areas are assigned 'ㅁ', 'ㄴ', 'ㅇ', 'ㄹ' and 'ㅎ' from the left, and the right four areas from the right 'l', 'ㅏ', 'ㅓ' and 'ㅗ' are assigned.

Of the nine areas except the edge of the last third row, the four left areas are assigned 'ㅋ', 'ㅌ', 'ㅊ' and 'ㄷ' from the left, and 'ㅠ' in order from the left of the five right areas. , 'TT' and 'ㅡ' are assigned. In this case, punctuation marks such as '-' may be allocated to the two remaining areas to the right. In FIG. 1, the right two regions except the edge of the first row are not used.

The left edge of the first row is assigned the 'Reject' key, the right edge is assigned the 'Backspace' key, and the left row of the second row has the 'Mode Switch' key. The "edge" key is assigned to the right edge area and the "shift" key is assigned to the left and right edges of the third row. At this time, the 'dismiss' key is used to cancel or discard the input string, and the 'confirm' key is used to confirm the input string. Also, 'Mode Switch' key is used to input meaningful numbers after Hangul.

The input device 10 according to an embodiment of the present invention assigns a number from 0 to 9 to a part of the 14 areas to which the vowel is assigned. For example, except for the edge area in the right area of the first row, four areas from the right, that is, 'TT', 'ㅡ' are allocated, and '0', '1', '2' and '3' are assigned, and '4' is assigned to three areas from the right, ie 'ㅓ', 'ㅏ' and 'l', except for the edge area in the right area of the second row. Assigns', '5' and '6', and has three areas from the right, ie 'ㅕ', 'ㅑ' and 'ㅐ', except for the two edges in the right area of the third row. '7', '8' and '9' may be respectively assigned to. The numbers assigned in this way do not use the 'shift' key.

In this way, the hand movement distance can be reduced when inputting a standardized Korean character string such as an address, so that the number can be entered quickly.

Referring to FIG. 2, the automatic input character converting apparatus 100 includes an automata processing unit 110, a string search unit 120, a string output unit 130, and a dictionary database 140.

Referring to FIG. 3, the automata processing unit 110 analyzes key values of input characters continuously input by a user using the input device 10 (S310), initial entry mode, Korean input mode, candidate selection mode, and numbers. A mode corresponding to the input character is selected among the input modes (S320). In this case, the automata processing unit 110 selects the initial consonant input mode when the input character is composed of consonants, selects the Korean input mode when the input character is composed of consonants and vowels, and the input character is composed of consecutive numbers. Select the numeric input mode.

The string search unit 120 includes a consonant-based string dictionary search unit 122, a Hangul-based string dictionary search unit 124, and a number-based string dictionary search unit 126, and includes a mode selected by the automata processor 110. Accordingly, the corresponding string dictionary search unit among the initial-based string dictionary search unit 122, the Hangul-based string dictionary search unit 124, and the number-based string dictionary search unit 126 operates, and the corresponding string dictionary search unit 122, 124, and 126 are operated. ) Searches for the string dictionary 142, 144, and 146 stored in the dictionary database 140 to search for a character string corresponding to the input character (S330).

The string output unit 130 outputs the searched string (S340).

The dictionary database 140 stores a string dictionary corresponding to each mode. That is, the dictionary database 140 includes a consonant-based string dictionary 142 corresponding to a consonant input mode, a Hangul-based string dictionary 144 corresponding to a Hangul input mode, and a number-based string dictionary 146 corresponding to a numeric input mode. The number-based string dictionary 146 stores postal codes and addresses.

4 is an operation state diagram of the automata processing unit shown in FIG. 2.

Referring to FIG. 4, after the consonant is input by the user (S401), when the consonants are continuously input (S402-S403), the automata processing unit 110 selects the initial input mode and switches to the initial input mode. Then, the consonant-based string dictionary search unit 122 operates to switch to the consonant-based search mode.

After switching to the initial input mode, if a vowel or number is input by the user (S404), the automata processing unit 110 selects the candidate selection mode because it is for selecting candidates for a character string corresponding to consecutively input consonants. And switch to the candidate selection mode. At this time, if the 'confirmation' key is input by the user (S405), the valid character string of the candidate corresponding to the input number is output.

If the vowels or numbers are continuously input after switching to the candidate selection mode (S406-S407), or if the vowels or numbers are continuously input (S408-S409, S407), this is because the user inputs a number, so that the automata processing unit 110 ) Selects the numeric input mode and switches to the numeric input mode. Then, the number-based string dictionary search unit 126 operates to switch to the number-based search mode. At this time, when the 'confirmation' key is input by the user (S410), a valid character string corresponding to the number input by the user is output.

If a vowel or number is input after the consonant is input by the user (S411), since the consonant and the vowel are combined, the automata processing unit 110 selects the Korean input mode and switches to the Korean input mode. Then, the Hangul-based string dictionary search unit 124 operates to switch to the Hangul-based search mode. The Hangul-based string dictionary search unit 124 searches for a string corresponding to a character input by the user in the Hangul-based string dictionary, and in this case, when the 'confirmation' key is input by the user (S412), The valid string corresponding to the number is printed.

If a vowel or number is input by the user after switching to the Hangul input mode (S413), the automata processing unit 110 selects the candidate selection mode and selects the candidate selection mode because it is for selecting a candidate for the consonant and the vowel string. Switch to The operation after switching to the candidate selection mode is performed in the same manner as described above.

On the other hand, if the 'change mode' key is input by the user after switching to the Hangul input mode (S414), since it is used when entering a meaningful number, the automata processing unit 110 selects the number input mode, the number Switch to input mode. The operation after switching to the numeric input mode is performed in the same manner as described above.

In addition, after switching to the Hangul input mode, the candidate selection mode, or the numeric input mode, if consonants are continuously input (S415-S417), the automata processing unit 110 switches to the initial input mode and then switches to the initial input mode. The operation is also performed as described above.

In addition, when the 'mode change' key is input by the user in the numeric input mode (S418), since this means selecting from a postal code candidate or address candidates, the automata processing unit 110 switches to the candidate selection mode. Then, when a vowel or number is entered by the user, the zip code or address corresponding to that number in the zip code candidate or address candidates is selected.

For example, when 's' and 'a' are sequentially input (S401 and S402), since consonants are continuously input, the automata processing unit 110 selects the initial input mode and switches to the initial input mode. Then, the initial consonant-based string dictionary search unit 122 operates, and the initial consonant-based string dictionary search unit 122 searches the initial consonant-based string dictionary consisting of 'ㅅ' and 'ㄱ' and outputs the string 130. ) Prints the search results. At this time, the string output unit 130 is' 1. Private life ',' 2. Offsetting, '3. Can be outputted as a candidate of three songs.

As such, after the candidate is output by the string output unit 130, when a user inputs a vowel or a number (S404), the candidate is selected from the candidates output by the string output unit 130. The automata processing unit 110 switches to the candidate input mode. At this time, when the user inputs the 'confirmation' key (S405), the string output unit 130 outputs a string corresponding to the number input by the user as a valid string.

For another example, when a user inputs 'ㅏ', 'ㅓ' and 'ㅣ' in sequence (S408-S409, S407), the automata processing unit 110 inputs 'ㅏ', 'ㅓ' and 'ㅣ'. Since it cannot be Hangul, it is judged as the number input mode and switches to the number input mode. Then, the string output unit 130 outputs the number '456' corresponding to 'ㅏ', 'ㅓ' and 'ㅣ'. At this time, the number-based string dictionary search unit 126 operates, and the number-based string dictionary search unit 126 searches for a postal code or address. Then, the string output unit 130 outputs a search result. If there is a candidate in the search result, when the 'change mode' key is input by the user, the number corresponding to the candidate is output, and when the user inputs the 'confirm' key (S410), the string output unit 130 may display the user. Prints the postal code or address corresponding to the selected candidate.
