Description

How to input Hangul using a mobile terminal and a mobile terminal {HANGUL INPUTTING METHOD BY USING MOBILE TERMINAL AND MOBILE TERMINAL}

The present invention relates to a method of inputting Hangul, and more particularly, to a Hangul input method using a portable terminal capable of easily and accurately inputting long Hangul sentences and a portable terminal to which the method is applied.

In general, a keypad adopted for a portable terminal has 12 4 * 3 combinations of ten numeric keys 0 to 9 and two control keys of '*' (hereinafter referred to as * key) and '#' (hereinafter referred to as #key). The matrix structure is used as the basic structure, and two or three alphabetic characters are arranged in duplicate on nine numeric keys 1 to 9 for English character input.

The number and arrangement of these keys is internationally standardized with respect to numbers and alphabetic characters input, hereinafter referred to as 'tenkey keypad' or 'keypad' for short. Each of the buttons is arranged a Hangul consonants from a to ㅎ and vowels, consonants and special characters designated by the manufacturer.

1A and 1B are diagrams for explaining an example of a portable terminal according to the prior art.

In the portable terminal shown in Fig. 1a, and it introduces the concept of a Hangul cloth (·) student principle of the bar, not (Ao), the (l) according as the input the Hangul bar. In other words, Cheonjiin method can input the desired vowel by selecting each key in the order of vowel writing by combining the three constituent strokes of the vowel, Cheon ( · ) stroke, Ji (ㅡ) stroke, and phosphorus (ㅣ) stroke. .

The input method of Hangul of FIG. 1A is easy to learn because it adopts the principle of Hangeul vowels as it is, while inputting a vowel having a large number of vowels constituting a vowel requires a large number of key button presses. For example, the double vowel 'ㅒ' is inputted by the sequential selection of the 'ㅣ', ' · ', ' · ' and 'ㅣ' keys, so the key button on which each key is placed must be sequentially pressed four times, and the ''ㅖ' is 4 times as' · ',' · ',' ㅣ 'and' ㅣ ',' ㅙ 'is 5 times as' · ', 'ㅡ', 'ㅣ', ' · ' and 'ㅣ', ''ㅞ','ㅡ',' · ', ' · ', 'ㅣ' and 'ㅣ' require five key button presses.

On the other hand, in the portable terminal shown in Figure 1b, for the input of the Hangul consonants 'AB', 'B', 'ㄹ', 'ㅁ', 'ㅅ', 'ㅇ' are arranged respectively, '입력', 'ㅗ', 'ㅣ', 'ㅡ' are placed on each of the four key buttons for inputting Korean vowels, but each key button with vowel 'ㅏ' and 'ㅗ' is placed 'ㅓ' and 'TT' is overlapping each other. In addition, for input of a double consonant and a stroke addition, a 'contrastance conversion' key and a 'add stroke' key are arranged on separate # keys and * keys. At this time, the vowels 'ㅓ' and 'TT' arranged in one key button are selected by pressing the corresponding key button twice consecutively.

In the Korean input method of FIG. 1B, since a plurality of vowel keys and consonant keys are arranged in one key button, several key button presses are required for inputting a consonant sound and a vowel sound. For example, since the double vowel 'ㅒ' is input by the sequential selection of the 'ㅏ', 'add stroke' and 'ㅣ' keys, the key button on which each key is placed must be sequentially pressed three times. 4 times with 'ㅓ', 'addition' and 'ㅣ', 'ㅙ' with 'ㅗ', 'ㅏ' and 'ㅣ' 3 times, 'ㅞ' with 'TT', 'ㅓ', and 'ㅣ Four key button presses are required.

As described above, the Hangul input method according to the prior art requires a large number of key button presses to input the Hangul, which not only causes inconvenience to the user, but also satisfies the user in terms of the input speed and accuracy of the Hangul. There was a difficult problem.

In an embodiment of the present invention, a candidate word matching the first consonant may be searched by first inputting only the first consonants corresponding to each syllable of one or more Hangul words, or a candidate word matching the initial consonant and the neutral by additionally inputting the second secondary. It provides a Hangul input method using a portable terminal that can search for.

In addition, an embodiment of the present invention inputs only the first consonants corresponding to each syllable of one or more Hangul words to search for candidate words matching the first consonants, or additionally inputs neutral to search for candidate words matching both initial and neutral. Provides a Korean input method using a portable terminal that can classify and search each candidate word by part of speech.

As a technical means for achieving the above-described technical problem, a first aspect of the present invention is the step of receiving a first consonant of each syllable of the word for one or more words belonging to the Hangul sentence from the user, the word corresponding to the input consonant Receiving the part-of-speech classification information of the user from the user, based on the received part-of-speech classification information and the input initial consonant, searching for a candidate word from a word storage unit, and searching the list of the retrieved candidate words according to preset criteria. And displaying the selected candidate words in the input area when sorting and displaying the selected candidate words in the input area when one of the displayed list of candidate words is selected by the user.

As a technical means for achieving the above-described technical problem, the second aspect of the present invention is a word storage unit for classifying and storing the Hangul word input by the user based on the part-of-speech classification information in a portable terminal capable of Hangul input, A key input unit configured to receive a consonant of each syllable of the Hangul word and part-of-speech classification information of the Hangul word from the user, and based on the input part-of-speech classification information of the Hangul word and the input consonant, a candidate word from the word storage unit; Provided is a portable terminal including a word search unit for searching and a word display unit for sorting and displaying the list of searched candidate words according to preset criteria.

According to one of the above-described problem solving means of the present invention, by entering only the first consonant corresponding to each syllable of one or more Hangul words to search for candidate words matching the first consonant, or by additionally entering the second secondary to the first consonant and By searching for candidate words matching neutral, one or more Hangul words to be input can be quickly and easily entered.

According to another one of the above-described problem solving means of the present invention, by entering only the first consonant corresponding to each syllable of one or more Hangul words to search for candidate words matching the first consonant, or by additionally entering the neutral to match the initial and neutral When searching for candidate words, it is possible to find a desired word more quickly by classifying each candidate word by parts of speech.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

Hereinafter, an apparatus and a method for inputting Korean characters using a portable terminal according to an embodiment of the present invention will be described with reference to FIGS. 2 to 5.

2 is a diagram for describing a method and a portable terminal for inputting Korean using a portable terminal according to an embodiment of the present invention.

Referring to FIG. 2, the mobile terminal 100 to which the Korean input method is applied according to an embodiment of the present invention may include an input area 110, a selection area 120, a function key area 130, and a keypad area 140. ).

The input area 110 displays Hangul consonants, Hangul vowels, numbers, special characters, and the like input by the user.

The selection area 120 displays a list of candidate words corresponding to the user's input consonant or corresponding to the consonant and the neutral in a form selectable by the user according to a user's request.

For example, when a user primarily inputs and searches only the first consonants corresponding to each syllable of one or more Korean words, such as "ㄱㄹ" in the input area 110, a list of candidate words matching the input consonants is preset. It is displayed in the selection area 120 according to the criteria.

The selection area 120 sorts the candidate words having the highest matching rate with the input first constellation, and ranks them in the order of the most frequently used candidate words or the most frequently used candidate words. Can be displayed.

For example, you can sort in order of candidate words with the highest match with the initial consonant "ㄱㄹ" entered, with the highest "horizontal" entered, followed by the most recently entered "copper". "Can be located. In addition, "ring", "path", "disturbance", etc., which are matched with "ㄱㄹ" and do not have high input frequency, may be located as a post-order.

It will be apparent to those skilled in the art that the above-described sorting order is merely illustrative, but not limited to.

The function button area 130 may include one or more function buttons, for example, a menu function button 131, a search function button 132, a call function button 133, an end function button 134, and an arrow key function button 135. It includes. One or more of these function buttons can be used as a candidate word search key for classifying and searching parts of parts of candidate words when searching for candidate words. For example, the menu function button 131 selects a candidate word to be searched for a noun group. The search function button 132 can be used as a "verb group search key" for searching from words belonging to the verb group for the candidate word to be searched. As such, when only the first consonant corresponding to each syllable of the word is first input and the candidate word search key is pressed, the position of the cursor on the input area 110 is moved to the neutral input position of the first letter of the word being input. A list of candidate words matching the input initials is displayed in the selection area 120. In addition, in the case of pressing a candidate word search key after additionally inputting a neutral corresponding to each syllable of a word, the position of the cursor on the input area 110 is moved to the final input position of the first letter of the word being input. A list of candidate words that match the input initial and neutral inputs is displayed in the selection area 120. In addition, one of these function buttons, for example, the call function button 133 can be used as a "selection area activation key" for activating the selection area 120. Detailed description thereof will be described later.

The keypad area 140 arranges a plurality of numeric keys and character keys for inputting Korean consonants, Korean vowels, numbers, and special characters.

3A to 3C are diagrams for describing a Hangul input method according to an embodiment of the present invention, respectively.

If the sentence that the user is trying to enter is, for example, "Jungjun goes to school", the user may write the sentence, for example, in a spacing unit, that is, "Jyungjun", "Go to school", " To enter.

As shown in FIG. 3A, a user primarily inputs only a consonant corresponding to each syllable of one or more words to be input, such as "AB" in the input area 110. When the initial entry is completed, the user inputs the part-of-speech classification information of the word being input using the "noun group search key" (for example, reference numeral 131 of FIG. 2). At this time, the position of the cursor on the input area 110 is moved to the neutral input position of the first letter of the word being input, and a list of candidate words matching the input first contiguous "ㄱㅈ" is displayed on the selection area 120. In this manner, in the state where only the first constellation is input, the desired word can be found more quickly by searching based on the part-of-speech classification information (noun group or verb group) without searching the entire candidate word.

The selection area 120 displays a list of candidate words searched from words belonging to the noun group, in which the list of candidate words is sorted by the rank of the candidate word having the highest matching rate with the input first entry "ㄱㅈ", of which The most frequently used "sticky" with the highest frequency of entry is located at the top, followed by the most recently entered "race". In addition, after the match with "ㄱㅈㅇ" in the ranking and the frequency of input is not high "millet", "eel", "princess" and the like can be located.

It will be apparent to those skilled in the art that the above-described sorting order is merely illustrative, but not limited to. That is, not only the candidate words corresponding to the part-of-speech classification information input by the user are displayed on the selection area 120, but words having a high matching rate with the inputted first consonant among words corresponding to other parts-of-speech classification information may be displayed together. have. That is, when a specific part-of-speech group information, for example, noun group information is input after receiving a consonant of each syllable of one or more words to be input by the user, the selection area 120 includes candidate words corresponding to the noun group. Candidate words that match 100% of the entered initials are displayed at the top, followed by candidate words that correspond to 100% of the entered initials among the other parts of speech, for example, verb groups. have. In the next rank, candidate words different from the candidate first name and one first name among candidate words corresponding to the noun group are displayed. Next, candidates different from the candidate first words and one first name among the candidate words corresponding to the verb group are different. The word may be located. In the next rank, candidate words different from the candidates entered in the noun group and the two selected first candidates are displayed. Next, candidates different from the candidate words entered in the verb group corresponding to the noun group and the two selected first candidates are listed. The word may be located.

In this manner, in the state in which only the first constellation is input, even if incorrect part-of-speech classification information is input by the user, the desired word can be found more quickly.

To select the "parallel" which the user wants to input from the list of candidate words displayed in the selection area 120, the selection area 120 is pressed by pressing the "selection area activation key" (for example, reference numeral 133 of FIG. 2). After activating, the numeric key “2” on the keypad area 140 may be selected, or the cursor on the input area 110 may be directly selected by using the direction key function button 135 on the function button area 130.

When one of the list of candidate words is selected by the user, the position of the cursor on the input area 110 moves to the initial entry position of the next word.

On the other hand, if there is no candidate word selected by the user from the list of candidate words displayed in the selection area 120, the neutral corresponding to each syllable of one or more words to be input from the user is secondarily input. That is, if an arbitrary character key on the keypad area 140 is selected after receiving the part-of-speech classification information from the user, the neutrality corresponding to the selected character key is displayed on the input area 110. Next, as shown in FIG. 3B, a method of inputting “in school” is primarily input only first consonants corresponding to each syllable of one or more words to be input, such as “ㅎㄱㅇ” in the input area 110. do. When the initial entry is completed, the user inputs the part-of-speech classification information of the word being input using the "noun group search key" (for example, reference numeral 131 of FIG. 2). At this time, the position of the cursor on the input area 110 is moved to the neutral input position of the first letter, and a list of candidate words matching the input first entry “ㅎㄱㅇ” is displayed in the selection area 120.

When one of the list of candidate words displayed in the selection area 120 is selected by the user, the position of the cursor on the input area 110 moves to the initial input position of the next word.

If the candidate word selected by the user does not exist in the list of candidate words, neutrality corresponding to each syllable of one or more words to be input from the user is secondarily input.

When neutral input is completed, the user inputs the part-of-speech classification information of the word being input using the "noun group search key". At this time, the position of the cursor on the input area 110 moves to the final input position of the word being input, and a list of candidate words matching the input primary and neutral "lower" is displayed on the selection area 120.

When one of the list of candidate words displayed in the selection area 120 is selected by the user, the position of the cursor on the input area 110 moves to the initial input position of the next word.

If the candidate word selected by the user does not exist in the list of candidate words, the finality corresponding to each syllable of one or more words to be input from the user is received in a third order.

Lastly, as shown in FIG. 3C, as shown in FIG. 3C, only an initial consonant corresponding to each syllable of one or more words to be input is primarily input to the input area 110, such as “ㄱㄷ”. . When the initial entry is completed, the user inputs the part-of-speech classification information of the word being input using the "verb group search key" (for example, reference numeral 132 of FIG. 2). At this time, the position of the cursor on the input area 110 is moved to the neutral input position of the first letter, and a list of candidate words matching the input initial letter "ㄱ" is displayed on the selection area 120.

When one of the list of candidate words displayed in the selection area 120 is selected by the user, the position of the cursor on the input area 110 moves to the initial input position of the next word.

If the candidate word selected by the user does not exist in the list of candidate words, neutrality corresponding to each syllable of one or more words to be input from the user is secondarily input.

When neutral input is completed, the user inputs the part-of-speech classification information of the word being input using the "verb group search key" (for example, reference numeral 132 of FIG. 2). At this time, the position of the cursor on the input area 110 moves to the final input position of the word being input, and a list of candidate words matching the input initial and neutral "go" is displayed in the selection area 120.

When one of the list of candidate words displayed in the selection area 120 is selected by the user, the position of the cursor on the input area 110 moves to the initial input position of the next word.

If the candidate word selected by the user does not exist in the list of candidate words, the finality corresponding to each syllable of one or more words to be input from the user is received in a third order.

So far, for convenience of explanation, it has been described as an example of classifying only noun group information and verb group information, but the present invention is not necessarily limited thereto, and may be classified into three or more parts, four or more parts of speech classification information. Do.

4 is a flowchart illustrating a Hangul input method using a portable terminal according to an embodiment of the present invention.

In operation S11, the portable terminal 100 classifies the Hangul word input by the user according to the part-of-speech classification information and stores the word in the word storage unit 150. In this case, the part-of-speech classification information may include, for example, noun group information including nouns, pronouns, investigations, investigations, interjections, adjectives, and adverbs, and verb group information including verbs and adjectives. In step S12, the portable terminal 100 sequentially receives the consonants of each syllable of the Hangul word to be input from the user. In this case, when the Korean word to be input is, for example, "Gyeong-Jun", the user may first input a consonant "AB" of each syllable corresponding to "Gyeong-Jun" in the input area 110.

In step S13, the portable terminal 100 receives the part-of-speech classification information (eg, noun group or verb group) of the word being input by the user, and then proceeds to step S14 to input each initial and part-of-speech input. The candidate word corresponding to the classification information is searched from the word storage 210. In this case, when the part-of-speech classification information of the word input by the user is noun group information, the candidate word is searched from the words classified as the noun group, and when the part-of-speech classification information of the word input by the user is verb group information, Candidate words can be searched from words classified into verb groups. In other words, when the part-of-speech classification information corresponding to the word "race" is being input from the user, that is, the noun group information is input, the portable terminal 100 searches for candidate words from words belonging to the noun group.

At this time, when the part-of-speech classification information of the word is input from the user, the portable terminal 100 moves the position of the cursor on the input area 110 to the neutral input position of the first letter of the word being input.

In step S15, the portable terminal 100 displays the list of retrieved candidate words in the selection area 120 in a form selectable by the user, and then proceeds to step S16, by the user among the displayed list of candidate words. It is determined whether the selected candidate word exists.

The searched candidate words are sorted in the order of high matching rate with the initial consonant "ㄱㅈ" entered among the words corresponding to the part-of-speech classification information input by the user. Can be displayed in sorted order.

In addition, the portable terminal 100 does not search only candidate words corresponding to the part-of-speech classification information input by the user, but searches for candidate words having a high match rate with the inputted first among the words corresponding to other parts-of-speech classification information. It may be displayed together with candidate words corresponding to the part-of-speech classification information input by the user. As such, the candidate words corresponding to other parts-of-speech classification information are also searched for and displayed together, so that even if an incorrect part-of-speech classification information is input by the user, a desired word can be found more quickly.

As a result of the determination in step S16, if there is a candidate word selected by the user, the flow advances to step S17 to display the selected candidate word in the input area 110, while the candidate word selected by the user is displayed. If it does not exist, the process proceeds to step S18 and the neutrality corresponding to the initial constellation input in step S12 is inputted from the user. That is, the portable terminal 100 receives the neutral "ㅕ ㅕ |" corresponding to each initial constellation inputted in step S12, for example, "AB", and displays it in the input area 110.

At this time, if one of the list of candidate words is selected by the user, the portable terminal 100 moves the position of the cursor on the input area 110 to the input position of the next word.

In step S19, the portable terminal 100 receives the part-of-speech classification information of the words corresponding to the initial and the neutral from the user, and then proceeds to the step S20 to input the initial and neutral parts and the input part-of-speech classification information. The corresponding candidate word is retrieved from the word storage 210.

In step S21, the portable terminal 100 displays a list of candidate words corresponding to the initial and neutral and the input part-of-speech classification information in the selection area 120, and then proceeds to step S22 and displays the displayed candidate words. It is determined whether there is a candidate word selected by the user from the list.

The retrieved candidate words are words that match the entered "muscle", and the sort order between these candidate words is based on the entered frequency or the selected frequency, as already described. In addition, the candidate words may be displayed in the order of high agreement between the initial and the neutral corresponding to each syllable of the input word.

As a result of the determination in step S22, if there is a candidate word selected by the user, the flow advances to step S23 to display the selected candidate word in the input area 110, while the candidate word selected by the user is displayed. If it does not exist, the flow advances to step S24 to receive a finality corresponding to each syllable of the word being input.

On the other hand, the portable terminal 100 according to an embodiment of the present invention does not search only the part-of-speech classification information of the noun group and the verb group. That is, the part-of-speech classification information according to the present invention merely distinguishes the central part-of-speech of the word to be input by the user as the noun group information or the verb group information. When the word being input consists of a combination of the noun and the verb, For example, "Night" is a core part-of-speech verb that performs a search from words classified as a verb group, but because it contains nouns, it can also search from words classified into a noun group. At this time, when searching for "night is" as the noun group information, it may be displayed at the bottom of the list of candidate words.

In addition, the portable terminal 100 according to an embodiment of the present invention classifies not only Korean words actually input by the user but also a plurality of Korean words registered in the Korean dictionary according to the part-of-speech classification information to the word storage unit 150. You can save it and use it when searching for candidate words. For example, when the Korean word “to school” that the user wants to input is a word that has never been used by the user, the portable terminal 100 may use the word “ㅎㄱㅇ from the words on the Korean dictionary stored in the word storage unit 150. The candidate word “school” matching ““ may be searched for and displayed on the selection area 120. In this case, the selection area 120 may display not only the noun “school” but also “e” to correspond to the user input “ㅎㄱㅇ” such as “to school”.
