The present invention relates to a method for inputting Hangul by using a character input means provided in a small terminal such as a mobile phone, and more specifically, 5 basic consonants of 10 Hangul consonants {ㄱㅁ, ㄴㄷ, ㄹㅂ, ㅅㅎ, ㅇㅈ } Separated consonant keyboard part, six Hangul basic vowels divided into three sets {ㅏㅗ, ㅣ ㅡ, ㅓ TT}, the vowel keyboard part arranged separately, the five keys and the basic vowels arranged 3 A character input device is configured as the first preceding combination key located at the shortest distance from the two keys and the second preceding combination key always set at the key position 0 regardless of the configuration of the keyboard portion. To generate a, but through a single character input means relates to a method for implementing two character input method.

In recent years, as the era of small-sized handsets, personal devices such as mobile phones, general telephones, walkie-talkies, and the like, integrated home remote control for home network realization, industrial controllers used in industrial sites, karaoke selectors, digital lock dials, and game machines Various industrial devices such as controllers, and many kinds of devices such as PDAs, smartphones, web pads, handheld PCs, etc., which will become the quintessences of the post PC era, will be equipped with small keyboards. There is also a need to develop a character input system that can be applied to various devices.

In order to meet the demands of the times, the character input method of Baekan Baekchul has been devised. Among them, representative patent applications related to the character input method using a small digital terminal keyboard are Korean Patent Application Registration No. 1998-0159191 (aka ' Cheonjiin 'method), Republic of Korea Patent Application No. 10-291838 (aka' Naratgle 'method), Republic of Korea Patent Application Publication No. 2002-0054059 (aka' Sky-2 'method) and the like.

Among the published applications disclosed in this way, Korean Patent Application No. 1998-0159191 (aka 'Cheonjiin' method), the vowels are arranged in the upper part of the keys are two fingers holding the terminal with both hands when typing with two hands There is a problem that this crossover is not natural, and when the character array format is changed, such as 6x2 array type, there is a problem that the balance of the vowel key array is broken, and when the consonant is generated, the method of pressing the same key continuously is used. In addition, forms such as 'ㅋㅋㅋ (= ク ク)' and 'ㅎㅎㅎ (= ㅎㅎ)', where consonants are listed as independent forms, are not entered in the battering method, but the battering forms such as 'ㅝ, ㅘ' are also battering methods. There is a problem that is not entered.

Republic of Korea Patent Application No. 10-291838 (also known as 'naratgle' method), after the two special keys (*, #) located in the lower corner of the keyboard portion back to the general numeric keys to generate a letter, If you hold in one hand and type in one hand, your fingers will need to frequent the bottom corners of the keyboard (*, # keys) frequently, so the one-finger fingering is unnatural and the vowels are arranged in a standalone fashion. There is a problem that a form such as 'ㅜㅜ' is not input in a battering method.

Republic of Korea Patent Application Publication No. 2002-0054059 (aka 'Sky-2' method), because the letters are arranged on all 12 keys provided on the keyboard, when you hold the terminal in one hand and type in one hand Since you have to travel back and forth to the bottom corner of the keyboard (* key, # key), one finger fingering is not natural, and the consonants are listed as independent 'ㅋㅋㅋ (= ク ク)', 'ㅎㅎㅎ (= ㅎㅎ)' Not only does not enter the form such as the battered method, there is a problem that the form, such as the vowel enumeration type 'TT TT, ㅗㅗ' is not also entered in the battering method.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and includes five basic Korean consonants in twelve-key character input means typically provided in a small digital terminal such as a mobile phone. ㅇ, ㅇㅇ}, and 6 Korean basic vowels separated into 3 sets {조, ㅣ ㅡ, ㅓㅜ}, and the central key located at the shortest distance from the consonants and vowels is the first key. As the precombination key, key 0 is set as the second precombination key to constitute the keyboard unit.

The first precombination key and eight keys (5 consonant keypads and 3 vowel keys) are combined to form a single independent character input method, and a second precombination key and 9 (consonants). A combination of five keys on the keyboard, three keys on the keyboard, and the first precombination key) is used to form one independent character input method.The two independent character input methods allow the user to Can be used at will according to the typing environment.

As described above, in the state where the five keys arranged with the basic consonants and the three keys arranged with the basic vowels are provided, the first to second pre-combined keys are provided to be pressed and combined before the eight keys.

First, the first precombination key at the shortest distance from the five keys arranged with the basic consonants and the three keys arranged with the basic consonants becomes the center key, and the eight adjacent keys are pressed at the center thereof. It's easy to hold with one hand and hit with one hand.

Second, the first precombination key is always located at the center of the keyboard regardless of the type of the keyboard, and the second precombination key is always located on one side of the keyboard regardless of the type of the keyboard. Even formats (3x4, 4x3, 6x2, 2x6, etc.) can be flexibly applied.

Third, since the first precombination key located at the center of the keyboard and the eight adjacent keys have already formed a complete set of character input methods, characters are combined using the remaining key 0 as the second precombination key. To increase the number of more, let's be able to enter all the Hangul alphabet standalone in the case of the increase. In this way, all Hangul alphabets, which were not possible in the conventional Hangul input method, can be input independently.

Therefore, in the present invention, any type of typing conditions (one-handed typing, two-handed typing), also the type of the keyboard part (3x4, 4x3, 6x2, 2x6), and any Korean type (syllable type, self-independent type) Whether or not everything is possible, the goal is to set and be devised.

In the present invention, in order to achieve the above object, the key located at the center of the keyboard portion of the small digital terminal is used as the first precombination key, and the zero key located at the bottom or the right side of the keyboard as the second precombination key. It is designed to implement an independent character input method, and a preferred embodiment for deriving the result of the implementation will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a character input system according to the present invention.

The character input system shown in FIG. 1 is composed of an input means 10 in the form of a keyboard part of a mobile phone and a control means 31 including a font and a character table 32. The display means 20 is added thereto. can do. Herein, the input means in the form of a mobile phone keyboard means a form in which 10 numeric keys and two special keys (*, #) are regularly provided, and is not necessarily limited to the shape of a mobile phone keyboard. Accordingly, the input means in the form of a keyboard part of a mobile phone according to the present invention is a concept including general telephones, portable communication terminal devices, information processing terminals and various remote controllers, and all the character input devices including the input means of this type. Applicable to

The Hangul input unit 10 shown in FIG. 1 is a 12-key type keyboard unit consisting of ten number buttons (1 to 9,0) and special function keys (*, #) normally provided on the keyboard. Hangul alphabet necessary to implement the present invention is arranged / assigned only to the number buttons, and the first precombination key and the second precombination key serve as preliminary combining keys of the numeric keys pressed next to the numeric keys.

The display unit 20 is a device capable of displaying an input character or graphic such as an LCD, and the corresponding letter is output whenever the letter is input so that the user inputs the letter correctly. Particularly, the input letter is displayed. In consideration of the context of the relationship between the consonants of the independent form, or consonants and vowels are displayed separately.

In addition, the controller 31 checks the signal input from the Hangul input unit 10 and controls the Korean consonants and vowels in the font and the character table to be composed and output as Hangul syllables according to a predefined combination rule. It is made of function.

2 is a diagram illustrating a principle of disposing Korean consonants and vowels on each numeric key that is the input unit 10 of the character input system according to the present invention.

Among the terms used in the following description, the term 'array' refers to a state in which characters are printed on a button and is visible, and the term 'array' refers to a state in which a plurality of keys on which characters are disposed are formed in a predetermined form. 'Assignment' refers to a character that is not printed on the button due to spatial constraints such as a small keyboard is placed in the position of the primary key having close morphological and phonetic correspondence.

In the arrangement of the Hangul consonants in the input unit 10, as shown in FIG. 2, in the present invention, letters are placed only on eight keys out of ten numeric keys, and the first precombination key is located at the center of the keyboard and the zero key is used. The second precombination key is set and configured.

One to three Korean alphabets are assigned to each button. In each button, '1' is the first character, '2' is the second character, '3' is the third character, and '4' is the fourth character. to be. Preferably, the first and second characters are printed on the button, and the third and fourth characters are preferably configured in a state allocated to the corresponding button, that is, in an assigned state, due to spatial constraints of the keyboard. Here, the letter not assigned to the keyboard is generated by combining the first to fourth characters.

Figure 3 is configured to correspond to the character assignment position of Figure 2, the consonant is {a, b, ㄹ, ㅅ, ㅇ} among the five basic consonants {ㄱㅁ, ㄴ, ㄹㅂ, ㅅㅎ, ㅇ} as shown in the drawing Arranged at the position of the first character of each button, {ㅁ, ㄷ, ㅂ, ㅎ, ㅈ} is arranged at the position of the second character, with four sensations (ㅋ, ㅌ, ,, ㅊ) and five consonants (ㄲ , ㄸ, ㅃ, ㅆ, ㅉ) are assigned to the key on which the basic person is placed, and are all assigned to the numeric key normally equipped with 19 consonants.

The vowel is composed of three basic vowels {ㅏㅗ, ㅣ ㅡ, ㅓㅜ}, {ㅏ, ㅣ, ㅓ} is arranged at the first character position, {ㅗ, ㅡ, ㅜ} is arranged at the second character position, and the double vowel {ㅘ , ㅢ, ㅝ} are assigned to the third character position, {ㅙ, ㅞ} is assigned to the fourth character position, and all 11 of the vowels are assigned to the button. The remaining 10 vowels (ㅑ, ㅕ, ㅛ, ㅐ, ㅐ, ㅔ, ㅒ, ㅖ, ㅟ) that are not assigned to the keyboard are generated by combining the first to fourth vowels, respectively.

In arranging the Hangul vowels in the input unit 10, as shown in FIG. 3, the vowels of 6 {ㅏㅗ, ㅣ ㅡ, ㅓ TT} with the highest frequency of occurrence among 21 Hangul vowels are arranged on the keyboard, and the remaining 15 vowels are arranged. Is assigned to the corresponding primitive position where the font's morphological correlation is tight. As a result, the key input unit 10 is arranged with 16 each of 8 numeric keys that are normally provided with 40 Korean alphabets, and the remaining alphabets are assigned to their basic key positions.

The character arrangement of the keyboard unit according to the present invention has been described with reference to FIG. 3, but the four-row by three-column array type as shown in FIG. 4A can be used as a four-way key type as shown in FIG. 4B.

As shown in FIG. 4C, the array of three rows by four columns with the {*, 0, #} key set to the right may be arranged, or the four rows may be arranged in the four direction key type as shown in FIG. It may be performed in an x6 column array type or in a 6 row x 2 column array type as shown in FIG. 4F. When the arrangement of the characters is performed in the four-way key type as shown in Fig. 4B / 4D, the first precombination key is located at the center of the keyboard portion as in the arrangement of Fig. 4A / 4C, and the key No. 0, which is the second precombination key, is the keyboard. Since it is formed in a line with the first precombination key located in the center of the negative, it will be recognized as the basic array type in terms of the arrangement form. 4e / 4f, when the arrangement form of the characters is configured to be two lines horizontally or vertically, the first precombination key located at the center of the keyboard is configured to be at the center of the vowel keys so that the balance of the basic form is maintained. do.

4A and 4B are exemplary views showing an example in which characters are arranged in four rows by three columns on the keyboard portion.

As illustrated in the above description, according to the present invention, the input means having at least ten buttons can be applied in various ways regardless of the form, and even if the arrangement of the letters is changed, Does not change

Therefore, although the character input system implemented from the present invention may be modified in such a way that the positions of the basic consonants or vowels arranged on the same key are interchangeable, the present invention pursues the above-described character arrangement principle. The practical and effective features of the character arranging method will never be modified.

5 to 7 illustrate input rules that can be commonly applied to the character arrays of FIGS. 4A to F. Among them, FIG. 5 is a rule for inputting 19 Hangul consonants, and FIGS. 6 to 7 show Hangul vowels 21. It is a figure explaining 15 input rules among the dogs.

As shown in FIG. 5, among 19 Korean consonants, {a, b, d, s, ㅇ} arranged at the first consonant position are inputted when the key on which the corresponding consonants are arranged is pressed once, and the second {ㅁ, ㄷ, ㅂ, ㅎ, ㅈ} arranged at the consonant position is inputted after the first precombination key is pressed once and the key with the corresponding consonant is pressed once, and assigned to the third consonant position. {ㅋ, ㅌ, ㅍ, ㅆ, ㅋ} is input when the first concatenation key is pressed two times in succession and then the first consonant key is pressed in turn, or when the first consonant key is pressed once and the first consonant key is pressed in turn. The {ㄲ, ㄸ, ㅃ, ㅉ} assigned to the fourth consonant position is inputted when the first consonant key is pressed three times in succession and then the first consonant key is pressed in sequence, or the zero key is pressed twice in succession. When the first consonant key is pressed in turn, it is inputted.

As shown in FIG. 6, {ㅏ, ㅣ, ㅓ} arranged at the first vowel position among 21 Korean vowels is inputted when the key on which the vowel is placed is pressed once, or the 0 key is entered once. After pressing, the key that is assigned to the vowel is pressed in order to be inputted, and the {ㅗ, ㅡ, ㅜ} placed at the second vowel position is entered when the key is pressed twice in succession, or the 0 key is pressed once. If the corresponding key is pressed twice in a row, {ㅘ, ㅢ, ㅝ} assigned to the third vowel position is entered if the key is pressed three times in succession, or if the number 0 key is pressed twice in a row, the first The vowels are placed in turn when they are pressed in sequence, and the {ㅙ, ㅞ} assigned to the fourth vowel position is entered when the key is pressed four times in succession, or after the third key is pressed three times in succession. When the keys arranged in turn are pressed, they are entered.

As shown in FIG. 7, {ㅑ, ㅕ} among the four re-collection vowels {ㅑ, ㅕ, ㅛ, ㅠ} is arranged with the corresponding main vowel {ㅏ, 회} after the first precombination key is pressed once. Key is entered in order, and {ㅛ, ㅠ} among the 4 re-vowels {키, ㅕ, ㅛ, ㅠ} is the key where {ㅣ ㅡ} is placed and the corresponding default vowel {ㅗ, ㅜ} is placed Pressed keys are pressed in sequence to be entered. The remaining six vowels (ㅐ, ㅔ, ㅒ, ㅖ, ㅚ, ㅟ), which are not placed / assigned on the keyboard, allow the first to fourth vowels to be combined.

Next, a combination method of six consonants {ㅐ, ㅔ, ㅒ, ㅖ, ㅚ, ㅟ} in addition to 19 consonants and 15 vowels in the above description will be described. A compound vowel is usually generated by combining the basic vowels.

ㅐ = ㅏ + ㅣ

ㅔ = ㅓ + ㅣ

ㅒ = ㅑ + ㅣ

ㅖ = ㅕ + ㅣ

ㅚ = ㅗ + ㅣ (= ㅏ + ㅏ + ㅣ)

ㅟ = ㅜ + ㅣ (= ㅗ + ㅗ + ㅣ)

Table 1 illustrates a rule for generating 40 Korean alphabets using the 3x4 format shown in FIGS. 4a / 4b and the 4x3 format shown in FIG. 4c / 4d among the various character array formats proposed by the present invention. According to the present invention, an independent character input method is established as a method of pre-input of the first precombination key, the fifth key, and another independent method of pre-input of the second precombination key, the zero key. Character input method is established.

For example, if you enter the word 'forearm', when you enter the first precombination key, (5-5-4) + ㅏ (3) + ㄹ (4) + ㄸ (5-5-5 -2) + TT (9-9) + ((1), and when entering the 2nd precombination key beforehand, ((0-4) + ㅏ (3) + ㄹ (4) + ㄸ (0 -0-2) + TT (9-9) As in the a (1), it is possible to make the result value obtained through one keyboard unit equal.

In addition, if you enter a form such as 'TT TT' to list the vowel standalone, press the '9' key twice like TT (9-9), and then return to the second precedent as TT (0-9-9). Only the vowels without consonants can be entered as stand-alone by inputting the key '0', which is a combination key, so that any type of vowel independent type can be entered continuously.

In the 6x2 format of FIG. 4E and the 2x6 format of FIG. 4F, like the 3x4 format or the 4x3 format, the first precombination key is located at the shortest distance from the consonant arrangement key and the vowel arrangement key, and the second precombination key '0'. Since the key is located at either end of the keyboard portion, the same typing condition is formed regardless of the type of the keyboard portion, and the principle of generating characters by combining the keys is maintained.

8 is a view for explaining the combined principle of the two bee method according to the present invention.

According to the present invention, an independent set of characters is input by a method of first inputting the first preceding combination key, and another independent character input method is performed by a method of inputting the second preceding combination key first. Depending on the user's typing environment or conditions, either one of these two input methods may be used, or both may be used in combination.

For example, when holding the terminal with one hand and tapping with one hand, use only the first precombination key located at the shortest distance from the consonant arrangement and the vowel placement, that is, at the center of the keyboard. When typing with two hands, if one of the two hands is fixed to the second precombination key (No. 0) located at either end of the keyboard, and both hands are used, the input efficiency can be further increased.

In addition, it can be seen that the input rule of the consonant / vowel shown in FIG. 8 can be applied regardless of the type of the keyboard. Whatever format the keyboard part takes, i.e., the 3x4 format shown in Figs. 4a / 4b, the 4x3 format shown in Figs. 4c / 4d, the 6x2 format with the left and right keyboard parts extended, the 2x6 format with the up and down lengths, or another In any form, if the first precombination key is placed at the shortest distance from the consonant arrangement and the vowel placement section, and the second precombination key is positioned at either end of the keyboard section, the characters are entered using the same rules in the keyboard of any form. can do.

For example, in the case of inputting a sensation consonant 'ㅋ', the first preceding combination key is pressed two times in succession, and a key is arranged in which the corresponding basic consonant 'ㄱ' is placed in turn, or the second preceding combination key is pressed. After pressing once, the key with the basic consonant 'ㄱ' is placed in order. In the case of inputting the old consonant consonant '입력', the first precombination key is pressed three times in succession, and then the key is placed after the corresponding basic consonant 'ㄱ' is pressed, or the second precombination key is pressed twice. Keys with the corresponding basic consonant 'ㄱ' placed are entered in turn.

As described above, the Hangul alphabet input rule by the two-stroke method according to the present invention is always realized regardless of the type of the keyboard portion, so that the result values of the two input methods obtained through one keyboard portion are always the same. . Therefore, by using the principle of the two-fold method according to the present invention, the type of typing environment (3x4, 4x3) of the user's typing environment (holding the terminal with one hand, pressing the button with one hand, pressing with both hands) 6x2, 2x6), two input rules can be used together through one keyboard unit.

In addition, the character input method using the two preceding combination keys according to the present invention, in addition to the original function of the corresponding key for inputting the Hangul alphabet as described above, by combining two prior combination keys, or two preceding combination keys and special keys By combining two (*, #) with each other, it is possible to execute a mode or a function that must be provided in the character input method. Also, a character type can be configured by matching a special character with the above key combination type. It may be.

E.g,

Press the first precombination key once + the key combination of the second precombination key (No. 0) corresponds to the 'symbol mode',

Press the first precombination key twice + the key combination of the second precombination key (number 0) corresponds to 'load character table',

1st precombination key press once + key combination of # to correspond to the 'line break' function,

Press the second preceding combination key (No. 0) 1 or 2 times + The key combination of the first preceding combination key corresponds to the input of 'special character',

The key combination of the second preceding combination key (0) + * key corresponds to the 'cancel' function.

The key combination of the second precombination key (No. 0) + # key may be configured to correspond to the 'space' (move one space to the right of the cursor).

As described above, two precombination keys may be combined with each other, or two precombination keys and two special keys (*, #) may be used to execute a mode or a function or to input a special character. It is possible to execute both modes and functions without moving the finger to the function key part (usually placed on the upper part of the number plate) provided that the user does not have to move back and forth to the function key part. Needless to say, it is not convenient to press the button, and no matter how the terminal is changed, there will be no problem in entering characters and executing functions.

As described in detail above, according to the character input means having a small keyboard portion according to the present invention, and a method of inputting characters by combining Korean consonants and vowels according to code values input from the character input means, A combination of the five keys and the vowel keyboard, in which the first precombination key is always located at the center and the second precombination key is located at the bottom or the right of the keyboard, regardless of the arrangement of the keyboard. Two independent character input methods can be used together through the character input means of.

By allowing two independent input methods to be crossed and used, in the form of easily holding the device with one hand like a remote control and pressing keys with one hand, the first precombination key located at the center of the keyboard is used as a combiner. In a device that is easy to hold and press with two hands, the second precombination key can be used as a combiner, thereby allowing the user to freely take the two postures, one-handed hitter and two-handed hitter.

In addition, in the character array format according to the present invention, the first precombination key is located at the center of the keyboard unit, even if the keyboard unit takes any arrangement (3x4 array, 4x3 array, 6x2 array, 2x6 array, circular array). Key 0 is located at the bottom or right side of the keyboard, there is an advantage that the order of the keyboard layout is not disturbed.
