Description

Korean character input device and method thereof of mobile communication terminal

The present invention relates to a Korean character input device and method of a mobile communication terminal, and more particularly, to input a Korean character in a mobile communication terminal such as a mobile phone or a PDA with one hand. The present invention relates to a Korean character input device and method for a mobile communication terminal which has a keypad arrangement optimized for one-handed use by minimizing the number of buttons and minimizing the number of button operations when inputting a vowel.

With the spread of mobile phones, PDAs, and text messaging services, Korean characters are increasingly input in handheld mobile communication terminals, which makes users more familiar with them and minimizes the number of button operations for input. Input methods are required.

In order to meet the needs of users, various methods for inputting Korean characters in a portable mobile communication terminal and a button arrangement method for simple recognition of input methods have been proposed.

With the rapid spread of the mobile communication terminals as described above, mobile communication terminal manufacturers such as Samsung Electronics, LG Information Communication, SKT and Motorola have developed and applied their own Korean character input method. Currently, the Hangul character keypad applied to the mobile communication terminal has the basic consonants such as' ㄱ ',' ㄴ ',' ㄷ ',' ㅂ ',' ㅅ ',' ㅈ ',' ㅇ 'and vowel' l ',' ㅇ ',' ㅡ 'is the way of heaven and earth, and the basic consonant is' ㄹ', 'ㅇ', 'ㅁ', 'ㄱ', 'ㄴ', 'ㅅ' and the basic vowel is' ㅏ ' Typical examples are naraggle, which are 'ㅗ', 'ㅡ', 'l'.

1A to 1D are views illustrating a keypad arrangement of Samsung Electronics, a keypad arrangement of LG information communication, a keypad arrangement of SK Sky terminal, and a keypad arrangement of Motorola terminal, respectively.

As shown in Figure 1a, the Korean character input method of Cheonjiin method assigns the vowels to the top three 'l', 'ㅇ', 'ㅡ' key, and the seven consonants below 'ㄱㅋ', After assigning to the 'ㄴㄹ', 'ㄷㅌ', ', ㄴ', 'ㅅㅎ', 'ㅈㅊ' and 'ㅇㅁ' keys, the user can enter 14 consonants and 10 vowels.

The Korean character input method of the Cheonjiin method uses a multi-tap method in which a button for inputting a consonant to be input is pressed one to three times to input the consonant. In the above, press the '4' once, 'b', press twice, 'ㅋ' and the button is not displayed, but press three times 'ㄲ' is input. In addition, when you enter a vowel, you do not have to memorize the vowel keyboard separately because you can press the button as you write. However, because you enter the vowel separately, you want to enter 'ㅙ'. If you press the button five times in total, the number of strokes is increased.

As shown in Fig. 1b, the Hangul method of Hangul character input method has a high error rate due to the high ratio of three characters to the initial consonant, and the neutral is distributed from one to six other characters. It's inefficient, so you can't help but reduce the number of strokes. Only in the finality, ㅁ, ㄴ, ㄹ is entered as 1 stroke, so only the number of strokes can be reduced. In this way, in the narrative method, since many strokes are used when inputting consonants and vowels, there is a problem in that the efficiency of input decreases. In addition, the vowel ㅑ, ㅕ, ㅛ, ㅠ input is a combination of ㅏ, ㅓ, ㅗ, TT and a function key (*), so there is a disadvantage that the association is not good when input.

As shown in FIG. 1C, the Hangul character input method of the sky method has a problem in that a consonant part is very vulnerable by dedicating a large number of keys to a vowel among 12 keypads. There is a slow problem.

As shown in FIG. 1D, the Korean character input method of the Motorola method is a combination of ㅏ, ㅓ, ㅗ, TT and a function key (#), similar to the narrative method in the case of the vowel ㅑ, ㅕ, ㅛ, ㅠ input. As a result, there is a disadvantage in that the association is not good at the time of input, and in the case of consonants, the input speed is slow because many consonants require two or more inputs.

On the other hand, in the Hangul character input method as described above, in the arrangement of consonants and vowels in the 3 ㅧ 4 keypad arrangement, the vowels are arranged in 1 to 3 and the consonants are arranged in 4 to 0, and the consonants are arranged. In the method, vowels are placed at 3, 6, 9 and 0 and consonants are placed in the rest. In the sky method, vowels are placed in 2, 3, 6, 7 and the function keys (#), and consonants are placed in the rest. In the Motorola method, the vowels are arranged in the 3 to 6 times and the consonants are arranged in the rest, and the respective Korean character input methods are the best Korean characters when using the keypad with both hands. It has a keypad arrangement for input.

However, Hangul input is composed of consonant first, vowel neutral, and consonant final. In general, mobile communication terminals are often held by one hand of the user. In many cases, especially in the case of consonant consonants should be arranged on the keypad of the number of 14 small numbers, it is inconvenient for the user to look at the consonant buttons at a glance, and thus the consonants and vowels of the keypad The arrangement is very inconvenient to use.

In addition, the keypad Korean character input methods as described above, assign a number 0 to 9 number keys for consonant and vowel input, and other function keys (*, By allocating up to #), the vowel conversion of the short vowels or the double consonant conversion of the terminal vowels is performed in addition to the input of the short vowel and the terminal vowels. There is a problem that the input of Hangul is required to learn, and also, the use of the keypad with one hand requires the user to use a keypad that is difficult to operate.

In addition, the keypad Korean character input methods as described above, the mobile communication terminal in addition to the number key and the function keys (*, #) provided in the keypad for the spacing function to prevent consonant collision generated when one button is used repeatedly. Because the use of the direction keys, the fingering distance increases due to the use of components other than the keypad when using the keypad with one hand, and the continuous input of Korean characters is disturbed when the keypad is used again after using the direction keys. There is a problem that it is difficult to input characters quickly.

In addition, the keypad Korean character input methods as described above, 10 basic vowel phonemes, 'ㅏ', 'ㅑ', 'ㅓ', 'ㅕ', 'ㅗ', 'ㅛ', 'TT', 'ㅠ', The input of 'ㅡ', 'ㅣ' is not made within 2 times, but sometimes it requires up to 3 inputs, and the double vowel phoneme, 'ㅐ', 'ㅔ', 'ㅘ', 'ㅚ', When the input of 'ㅝ', 'ㅟ', 'ㅖ', 'ㅢ', 'ㅞ', 'ㅒ', 'ㅙ' is not entered in the order of the vowel vowels, for example, in the case of the vowel 'ㅙ' Since 'ㅗ', 'ㅏ', 'l' or 'ㅗ', 'ㅐ' must be entered, '복', 'l', 'ㅗ' or 'ㅐ' If you input ',' ㅗ ', etc., a typo will be generated.Therefore, there is a hassle to operate the direction change key or the cancel or clear key of the mobile communication terminal other than the keypad. Hangul characters for low-ability children, senior citizens, or foreigners There are forces is very difficult.

Accordingly, the present invention has been invented to solve the above problems, an object of the present invention is to arrange the consonants at the top of the keypad and to arrange the vowels at the bottom of the keypad so that the user looks at the consonant buttons at a glance with one hand. Another object of the present invention is to provide a Korean character input device and method of a mobile communication terminal having a keypad arrangement optimized to enable simple Korean character input.

In addition, another object of the present invention is to reduce the keypad share of the phonemes for inputting Hangul characters in a position difficult to operate according to the hand used by the user, the user can easily learn the arrangement of the keypad and use the keypad It is to provide a Hangul character input device and method of the terminal.

In addition, another object of the present invention is to provide a function key having a cursor movement and a space input function to the next character position when inputting the Hangul characters are provided on the number keys of the keypad to minimize the fingering distance and to enable rapid character input It is to provide a Hangul character input device and method of a mobile communication terminal.

In addition, another object of the present invention is 10 basic collection phonemes, 'ㅏ', 'ㅑ', 'ㅓ', 'ㅕ', 'ㅗ', 'ㅛ', 'TT', 'ㅠ', 'ㅡ' It is to provide a Korean character input device and method of a mobile communication terminal that can reduce the number of strokes and enable rapid character input by allowing input of ',' to be made within two times.

Depending on the type, 'ㅈ', 'ㅎ', 'ㅊ' and 'ㅉ' are entered.

The consonant consonants inputted by the plurality of consonant buttons S as described above are shown in Table 1 below.

[Table 1 Consonant phoneme input method using a plurality of consonant buttons]

Consonant phoneme (same for both right and left handed users) Jaso Numeric Key Input Method Number of presses division A One One Terminal sound
(Basic consonant + sound) N 2 One C 3 One D 4 One M 44 2 ㅂ 22 2 S 55 2 ㅇ 5 One ㅈ 6 One H 666 3 Lol 11 2 ㅌ 33 2 ㅍ 222 3 ㅎ 66 2 ㄲ 111 3 Double consonants ㄸ 333 3 ㅃ 2222 or 252 4 or 3 ㅆ 555 3 ㅉ 6666 or 656 4 or 3 ㄻ 444 3 Consonant (double consonant) ㄳ 155 3 ㄵ 26 2 ㄶ 266 3 ㄺ 41 2 ㄼ 422 3 ㄽ 455 3 ㄾ 433 3 ㄿ 4222 4 ㅀ 466 3 ㅄ 2255 4

Therefore, according to the plurality of consonant buttons S as described above, a total of 30 consonant phonemes may be input by using only six numeric keys N in total.

In addition, in the case of 'ㅃ' and 'ㅉ' of the consonants of the consonant phoneme, respectively, the numeric keys (N) '2' and '6' are inputted a total of four times, but in order to reduce the number of times, the numeric keys (N ) '5' to have a conversion key function for converting to two consonants, for example, the number key (N) '2' or '6' once input of the number key (N) '5' once When the number key (N) '2' or '6' is input once again, the 'ㅃ' or 'ㅉ' is inputted so that all terminal sounds and double consonants are input through a total of three or fewer key inputs. You can do that.

In addition, when the numeric key (N) '4' of the consonant button (S) is input three times, 'ㄻ' is input in a situation in which a finality is input and 'ㄹ' is input in a situation in which a consonant is input. The input can be made quickly.

On the other hand, the plurality of vowel buttons (V), the digit 'N' is placed on the vowel 'ㅏㅓ' so that '되어', 'ㅓ' is displayed according to the number of presses, and the numeric key (N) ' The vowel 'ㅗ TT' is placed in '8' so that 'ㅗ' and 'TT' are displayed according to the number of pressing. The digit 'N' '9' is placed in the vowel 'ㅣ ㅡ' and the number of pressing 'ㅣ' , 'ㅡ', 'ㅢ' is displayed, and the function key (F) '*' or '#' is placed on the vowel 'ㅕ ㅠ' and '되어', 'ㅠ' is displayed depending on the number of times of pressing. Be sure to

The vowel elements represented by the plural vowel buttons V as described above are shown in Table 2 below.

TABLE 2 Multiple  By vowel button Vowel  Input method]

Therefore, according to the plurality of vowel buttons V as described above, all of the vowel elements can be input using only three numeric keys N and one function key F. FIG.

In addition, in the case of 'ㅑ' and 'ㅛ' among the vowels of the vowel phoneme, the button having the vowel 'ㅕ ㅠ' among the function keys '*' or '#' is arranged to reduce the number of inputs respectively. For example, the numeric key (N) '7' or '8' is entered once, and the function key (F) '*' or '#' of the vowel 'ㅕ ㅠ' is arranged. When the button is input once, the 'ㅑ' or 'ㅛ' is input so that 10 basic vowel phonemes, 'ㅏ', 'ㅑ', 'ㅓ', 'ㅕ', 'ㅗ', 'ㅛ', 'ㅜ', 'ㅠ', 'ㅡ', 'ㅣ' can all be entered.

On the other hand, the space button (SP) is disposed in the '0' of the numeric keys (N), when the number key (N) '0' is input when the phoneme of the consonants or vowels for entering Korean characters In the case of inputting the text, the cursor is moved to the next letter position without inputting a blank to prevent consonant collision. If the text is not being input, the blank input is made.

In other words, if you are typing a Hangul character, you need to enter the space button twice to open a space. First, press the space once to move the cursor to the next character position from the current letter, then press the space again to open a space. . The reason why the space press during character input does not immediately input a blank space but moves to the next character is to avoid consonant collision caused by the multi-tap input method. For example, in the multi-tap input method, the Korean character 'country' If you input 'station' after inputting 'ga' consecutively, 'guka' is input.In order to prevent the consonant collision, enter 'station' and then enter the space button (SP) once. By moving the cursor to the next letter position and entering 'ga', it can be entered as 'country'.

Therefore, according to the space button (SP) as described above, a button having a function of moving a cursor and a space input function is provided on the numeric key N '0' on the keypad input unit 110, and the next letter of Korean characters is input. It is possible to shorten the fingering distance by not using a direction change key (not shown) of the mobile communication terminal provided in addition to the keypad input unit 110 to move the cursor to a position and input a space.

In addition, by enabling the continuous input of Hangul characters, that is, entering the keypad and moving the cursor to the next character and pressing the direction switch key away from the keypad for the function of entering blank spaces By enabling, you can quickly input Korean characters.

In addition, when inputting a sentence and then adding new content in the middle of the sentence, it is difficult to input a space in Cheonjiin, Naratgle, etc., but the present invention can input a space using a direction key and a space button.

On the other hand, the special character button (SC), the special character '?.' Is placed on any one of the '*' or '#' in which the vowel button V for vowel input among the function keys F is not arranged. According to the number of pressing, '?' Is input once, '.' Is input twice, and 'Special Characters' window is opened three times.

Therefore, according to the special character button SC as described above, a button having a function for inputting a special character is provided on any one of the function keys '*' or '#' on the keypad input unit 110 and the button Frequent use of '?' Or '.' Is directly input, by entering the Hangul characters do not need to open a special character window using the special character function keys of the mobile communication terminal provided in addition to the keypad input unit 110 to input the special characters among the Hangul characters. Can be enabled quickly.

Here, '*' or '#' of the function key (F), when the user mainly uses the left hand, the special character button (SC) is arranged in the '*' and the vowel button (V) in the '#' When the user mainly uses the right hand, a vowel button (V) is disposed at the '*' and a special character button (SC) is disposed at the '#', and the frequency of use is high in a position where the finger is easy to approach. The vowels can be arranged to enable easier Korean character input.

Arrangement of the consonant button (S), the vowel button (V), the space button (SP) and the special character button (SC) corresponding to the input of the numeric keypad (N) and the function key (F) as described above Table 3 shows an example of the number of times and the number of inputs accordingly and the phoneme displayed on the display 120 as follows.

Therefore, according to the keypad input unit 110 as described above, the plurality of consonant buttons S are arranged on the upper side of the keypad input unit 110, that is, '1' to '6' of the numeric keys N, The vowel button V is arranged on the lower side of the keypad input unit 110, that is, on any one of '7' to '9' of the numeric keys N and '*' or '#' of the function keys F. When using the mobile communication terminal by hand, the consonant button (S) for consonant input is placed on the part which is not covered by the finger so that the user who can not memorize the keyboard can quickly find the consonant phoneme. have.

In addition, the phonemes for inputting Hangul characters are prevented from being placed in a location that is difficult for the user to operate. That is, a frequently used vowel has a '*' or '#' among function keys F depending on the user's hand. Optionally placed in any one of the user can simplify the learning of the arrangement of the keypad and the use of the keypad.

In addition, a space button (SP) having a function of moving a cursor and a space input function is provided on the numeric key N '0' of the keypad when the Korean character is inputted. By not using it, the fingering distance can be minimized and quick character input can be performed.

Also, the input of 10 basic vowels, ',', ',', 'ㅓ', 'ㅕ', 'ㅗ', 'ㅛ', 'TT', 'ㅠ', 'ㅡ', 'ㅣ' It can be done within two times to reduce the number of strokes and to enable fast character input.

On the other hand, the display unit 120 is a display means such as a known LCD for outputting the Hangul characters input from the keypad input unit 110, it is preferably provided in the mobile communication terminal.

On the other hand, the Hangul character completion unit 130 reads the phoneme corresponding to the input of the keypad input unit 110 from the pre-stored database (DB) and combines the read phoneme into Hangul characters to provide it to the display unit 120 In the database DB, as shown in Tables 1 to 3, a consonant phoneme input, a vowel phoneme input, a cursor movement to the next letter position, a space input, and a special character corresponding to the input of the keypad input unit 110 are provided. Data for enabling input, 'ㅃ' or 'ㅉ' conversion input, and 'ㅑ' or 'ㅛ' conversion input are stored, and according to the input generated from the keypad input unit 110 by the user, It performs a function of completing the corresponding Hangul character by combining the cursor movement to a character position, inputting a blank space, a special character, and a conversion input and providing the same to the display unit 120.

Therefore, according to the Hangul character completion unit 130 as described above, the vowel vowel phoneme, 'ㅐ', 'ㅔ', 'ㅘ', 'ㅚ', 'ㅝ', 'ㅟ', 'ㅖ', 'ㅢ', ' When inputting ㅞ ',' ㅒ ',' ㅙ ', the input of the vowel is automatically completed so that the vowel is automatically completed.

Hereinafter, a method of inputting Korean characters of a mobile communication terminal having a keypad arrangement optimized for one-handed use according to a preferred embodiment of the present invention having the above configuration will be described.

4 is a control flowchart illustrating a Hangul character input method of a mobile communication terminal according to an embodiment of the present invention.

First, as shown in FIG. 4, a corresponding phoneme is input from the keypad input unit 110 while the user enters a mode for inputting Korean characters through a corresponding function key of the mobile communication terminal (S100).

Thereafter, the Hangul character completion unit 130 determines whether the phoneme input in the step is a consonant (S105).

If the inputted phoneme is a consonant as a result of the determination in step S105, continuous input of the same key or continuous input of the same key for the vowel function, the horn function, and the support function is performed by the Hangul character completion unit 130 after the phoneme character. It is determined whether it is generated (S110).

Subsequently, when the determination result of the step S110 is a continuous input of the same key or multiple keys for the voicing function, the horn function, and the supporting function after the phoneme character, the lattice of the phoneme input by the Hangul character completion unit 130 is generated. A sound or a hard consonant or a consonant consonant is output to the display unit 120 (S115), otherwise, the basic consonant corresponding to the input phoneme is output to the display unit 120 by the Hangul character completion unit 130. (S120).

In other words, the Hangul character completion unit 130, 'a', 'ㄷ' at the time of entering the number key (N) '1', '3', '4', '5' of the consonant button (S), respectively , 'ㄹ', 'ㅇ' are printed, and when input twice, 'ㅋ', 'ㅌ', 'ㅁ', 'ㅅ' are output, respectively, and when input three times, 'ㄲ', 'ㄲ', ' ㄻ (in case of support) ',' ㅆ ' In addition, the Hangul character completion unit 130 is a number key (N) '2', '6' of the consonant button (S) is input once each, and after the number key (N) '5' is input once When the numeric keys 'N' '2' and '6' are inputted once, respectively, 'ㅃ' and 'ㅉ' are outputted, and when the numeric keys (N) '2' and '6' are inputted once Print 'b' and 'ㅈ' respectively, print 'ㅂ' and 'ㅎ' twice when input two times, print 'в' and 'ㅊ' after three input times, and enter '' Output ㅃ ',' ㅉ '. In addition, the Hangul character completion unit 130 outputs a consonant (double consonant) when a plurality of keys are continuously or singularly input following a single or multiple input of the same key among the consonant buttons (S).

On the other hand, if it is determined in step S105 that the input phoneme is not a consonant, the Hangul character completion unit 130 determines whether the input phoneme is a vowel (S125).

 As a result of the determination in step S125, if the input phoneme is a vowel, the Hangul character completion unit 130 determines whether the phoneme is a combination phoneme by a plurality of key inputs (S130).

Subsequently, if the phoneme is a combination element, that is, a vowel vowel by a plurality of key inputs (except the function key (F) input), the combination corresponding to the plurality of key inputs by the Hangul character completion unit 130 is determined. The vowel is output (S135), otherwise, the vowel corresponding to the input phoneme is output by the Hangul character completion unit 130 (S140).

In other words, the Hangul character completion unit 130, 'ㅏ' of the digit buttons (N) '7' to '9' and the function key (F) '*' or '#' of each of the 'ㅏ' It outputs', 'ㅗ', 'ㅣ', 'ㅕ', and when it enters twice, it outputs' ㅓ ',' TT ',' ㅡ ',' ㅠ 'respectively. When input 3 times, '입력' is output. In addition, the Hangul character completion unit 130 is the 'ㅑ' or when the function key (F) '*' or '#' is input once after the numeric key (N) '7' or '8' is input once Let 'ㅛ' be printed. In addition, the Hangul character completion unit 130, a single or multiple input of the same key of the numeric key (N) '7' to '9' and the function key (F) '*' or '#' of the vowel button (V) Subsequently, when a plurality of keys are repeatedly input in succession, a combination vowel, that is, a vowel vowel as shown in Tables 2 and 4 is output.

On the other hand, if the determined phoneme is not a vowel as a result of step S125, it is determined by the Hangul character completion unit 130 whether the input phoneme is a space (S145).

As a result of the determination of step S145, if the input phoneme is a space, the Hangul character completion unit 130 combines the Hangul characters (that is, to combine the consonants of the consonant and the vowels of the neutral and the consonants of the final consonant into one character. Input), and if the Hangul characters are being combined as a result of the determination of S150, the cursor is moved to the next character to prevent consonant collision (S155), and the Hangul characters are determined. If not in combination, a blank is input (step S160).

In other words, the Hangul character completion unit 130 moves the cursor to the next character when the characters are being combined in the character writing window of the current Hangul character input mode when the numeric key (N) '0' is inputted, If the combination is completed, input blanks.

On the other hand, if the inputted phoneme is not a space as a result of the determination of step S145, the inputted phoneme is determined as a special character by the Hangul character completion unit 130, and the corresponding special character is determined by the Hangul character completion unit 130. It is output (S165).

In other words, the Hangul character completion unit 130 outputs a '?' At any one time of the function key (F) '*' or '#' in which the vowel button is not disposed, and '.' ', And prints the special character collection window after entering 3 times.

Table 5 shows an example of inputting the same sentence in the Korean character input method and the conventional Korean character input method as described above.
