Abstract

A Korean character input apparatus and method of a mobile terminal are provided to improve Korean character input speed so that the user can input a consonant with high frequency by one stroke and a consonant with low frequency by two or three times of strokes. A keypad(120) includes six consonant input keys with 'giok', 'nyeun', 'digeut', 'mieum', 'siot' and 'ieung' assigned thereto and a special key to be used together with one of the six consonant input keys to input one of consonants of 'ryeul', 'bieup', 'gieut', 'tigeut', 'pieup' and 'hieut'. A consonant/vowel code table(321) stores code values of each formant inputted from the keypad(120). A consonant/vowel separating unit(311) converts an input signal generated by a key, among the keys of the keypad(120), into a corresponding code value stored in the consonant/vowel code table(321). An automata(320) generates Hangul codes of an initial sound, a medial vowel, and a final consonant by combining the converted code value. When the special key is pressed twice consecutively, 'chiut' is inputted.

The present invention relates to a Hangul input device and method of a portable terminal to enable easier input of Hangul in a portable terminal, and more particularly, to a Hangul input device of a portable terminal for inputting Hangul with a minimum of key operation. And to a method.

In recent years, the penetration rate of the portable terminal is rapidly increasing and it is becoming a living necessity of modern people. Such a portable terminal is provided with a function of inputting or transmitting a variety of information as well as a telephone function. Recently, a short message service (SMS) has been used a lot. To this end, the caller inputs characters such as Korean or English using a plurality of keys formed on the keypad of the portable terminal.

However, in the case of a portable terminal, all consonants and vowels of the Hangul must be input using a very limited number of keys. Therefore, in order to input one consonant or vowel, it is necessary to press the same key at least once and up to four times. It became.

Meanwhile, with the rapid spread of portable terminals, terminal manufacturers such as Samsung Electronics, LG Information and Communications, Hyundai Electronics, and Motorola have developed and applied their own Hangul input method. Currently, Hangul keypads that are applied to portable terminals are divided into two methods, a cheonjiin method and a naragle method.

The Cheonjiin method is divided into seven phonemes, the basic consonants of "a, b, c, ㅂ, ㅅ, ㅈ, ㅇ" is assigned to each key of the terminal, the basic vowel is "ㅣ, ㆍ, ㅡ" It is classified into three phonemes and assigned to each key of the terminal. In the narrative method, the basic consonants of consonants are classified into six phonemes of “ㅇ, ㅁ, a, b, ㅅ, ㄹ” and assigned to each key, and the basic vowels of “vowels” are “ㅏ, ㅗ, ㅡ, ㅣ”. It is classified as a phoneme and assigned to each key of the terminal.

According to the method of classifying the basic consonants and the basic vowels of the consonant and the method of assigning the classified basic characters to each key on each keypad formed in the portable terminal, the method of inputting Korean characters is greatly different. Alternatively, when entering a sentence, the stroke at which the key of the portable terminal is pressed varies greatly.

The Hangul input method of the conventional portable terminal will be described in detail as follows.

The "Cheonjiin way" is divided into seven basic characters (a, b, c, ㅂ, ㅅ, ㅈ, ㅇ), and the vowels are classified into three basic characters (ㅣ, ㆍ, ㅡ) to the portable terminal After assigning to each key of the formed keypad, it is possible to selectively input 14 consonants and 10 vowels respectively. By the way, in this natural input method, 14 consonants are assigned to 7 keys, each of which is input by one or two presses, while 10 vowels have to be inputted several times with only three keys. As a result, when the vowel input is inevitable, the number of key presses are inevitably large, which is cumbersome and causes a waste of time.

For example, in a vowel, you must press two keys once for "ㅏ" and two keys for "ㅑ" with one key pressed twice while the other key pressed twice. You should press a total of three times, and in the case of "ㅙ" you should press as many times as close to a total of five times. Since vowels are essential to any sentence with a consonant for each Hangul character, the ease of vowel input can have a huge impact on the overall efficiency of Hangul input. This "Cheonjiin" method has a large number of vowel input strokes. There was discomfort.

As pointed out above, the arrangement of consonants in the celestial way is seven characters long, for example, because the sound (타, ㄸ, ㅃ, ㅆ, ㅉ) has to hit three strokes in a row, there is a high probability of a typo. The relations of "," ㅎ "and" ㅁ "are arbitrarily arranged without following the necessary associations, and the user is likely to make a mistake in character association. Also, the array of vowels is simple because the base has three characters, but one stroke per stroke is used, so many strokes are used to enter the vowel. For example, in the case of a double vowel, as described above, since there are 4 to 5 strokes, there is a high probability of a typo, and according to the distribution of the strokes, three phonemes are used and eight phonemes occupy a high ratio, so the method of heaven and earth is in the vowel. Overall, the typo rate is high.

Meanwhile, in the naragle method, consonants are classified into six phonemes of “ㅇ, ㅁ, a, b, ㅅ, ㄹ” to reduce one phoneme compared to the Cheonjiin method, and the basic vowels of the vowel “ㅏ, ㅗ, ㅡ, ㅣ” 4 The phoneme was classified into phonemes and assigned to each key formed on the keypad of the portable terminal by increasing one phoneme than the Cheonjiin method. This has the advantage that the number of strokes for inputting vowels is greatly reduced than the cheonjiin method, but the disadvantage is that the number of strokes for inputting consonants is relatively larger than the cheonjiin method.

The naragle method has a high error rate because of the high ratio of three letters to initial characters. In addition, since neutrality is distributed from 1 stroke character to 6 stroke characters, 3 or more strokes may be required in order to input the said neutrality. When three or more strokes are required to input one phoneme as described above, the error rate is high and the input efficiency is inevitably reduced. Only in the finality, "ㅁ", "ㄴ", and "ㄹ" are input as 1 stroke, so only the number of strokes can be reduced. In this way, in the narrative method, since a large number of strokes are used when inputting consonants and vowels, there is a problem in that the efficiency of input decreases.

As described above, in the Korean input method of a conventional portable terminal, it is difficult to properly assign a limited key as a key for inputting a consonant and a key for inputting a vowel. Therefore, there is an urgent need for an effort to improve the conflicting part of the number of strokes inputting consonants and the number of strokes inputting vowels, as in the above-described cheonjiin or naratgle.

Accordingly, an object of the present invention is to efficiently classify and assign a key for inputting consonants and a key for inputting a vowel to a key of a portable terminal having a limited number, so that the mobile terminal can be input with only minimal key manipulation. It is to provide a Hangul input device and method of.

Apparatus for achieving the above object; In the apparatus for inputting Hangul by using a key input means formed outside the portable terminal, the key input means may include six of "ㄱ", "b", "c", "ㅁ", "ㅅ" and "ㅇ". Each of the six consonant input keys and one of the six consonant input keys assigned to each of the different consonants are assigned to one of the six consonant input keys, which are then used with the letters "ㄹ", "ㅂ", "ㅈ", "ㅌ", " A keypad configured to include a special key for inputting a consonant of any one of ㅋ "," ㅍ "and" ㅎ "; A consonant code table that stores code values for each phoneme input from the keypad; A consonant separator for converting a key generated from an input signal among a plurality of keys included in the keypad into a corresponding code value from a code value stored in the consonant code table; And an automata that combines the converted code values to generate Hangul codes of initial, neutral, and longitudinal.

In addition, the keypad is used together with any one of the four keys of "a", "c", "ㅁ", and "ㅅ" to be used among "ㄲ", "ㄸ", "ㅃ" and "ㅆ". It further comprises a repeating key for inputting any one consonant.

In addition, the keypad has a pair of "ㅏ" and "ㅓ", "ㅗ" and "TT" are paired, "ㅣ" and "쌍" are paired, and "ㅡ" and "ㅠ" are paired. The pairs may further include four vowel input keys each pair assigned to different keys except for the consonant input key.

In addition, if the "c" key is pressed after the special key is pressed consonant "d" is characterized in that is input.

In addition, when the special key is pressed twice in a row, the consonant "vo" is characterized in that it is input.

In addition, if the special key is pressed after the "ㅁ" key is pressed consonant "pl" is characterized in that is input.

The method for achieving the above object; In the method for inputting Hangul by using a key input means formed outside the portable terminal, each key included in the key input means is a "b", "b", "c", "ㅁ", "ㅅ", Assign one of six different consonants of "ㅇ" one by one, and use any of the six keys together with a special key to make "ㄹ", "ㅂ", "ㅈ", "ㅌ", "ㅋ", Characteristic input of any one of "et", "ㅎ".

Further, any one of the four keys of "a", "c", "ㅁ" and "ㅅ" and a repeating key may be used together to select any of "ㄲ", "ㄸ", "ㅃ" and "ㅆ". It is characterized by inputting one consonant.

In addition, "ㅏ" and "ㅓ" are paired, "ㅗ" and "TT" are paired, "ㅣ" and "ㅕ" are paired, and "ㅡ" and "ㅠ" are paired. Each pair is assigned to different keys except for the consonant input key to input vowels.

In addition, if the "c" key is pressed after the special key is pressed consonant "d" is characterized in that is input.

In addition, when the special key is pressed twice in a row, the consonant "vo" is characterized in that it is input.

In addition, if the special key is pressed after the "ㅁ" key is pressed consonant "pl" is characterized in that is input.

In the above description, a method of inputting 14 consonants of Korean alphabet "a, b, c, d, k, k, k, k, k, k, k, k, k, p, h" has been described. An input method of X, Y, Y, Y "will be described later.

The consonants "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ" has a shape in which the corresponding consonants "a, c, ㅂ, ㅅ, ㅈ" are used twice in succession. This can be easily input using the repeat key 127 shown in FIG. The consonant "ㄲ, ㄸ, ㅆ" is input by pressing the repeating key 127 after pressing the corresponding consonants "a" (121), "c" (123), "s" (125).

)(128), "ㅁ"(124)키 및 반복키(127)를 순차적으로 누름으로써 입력이 가능하게 구현할 수도 있다. However, since "ㅂ" and "ㅈ" are consonants that can be input by synthesis rather than the basic elements in the present invention, "ㅃ" is input by pressing the "ㅁ" 124 key and then repeatedly pressing the repeat key 127. . Meanwhile, as described above, a special key for inputting the consonant "ㅂ" (

) 128, the "ㅁ" (124) key and the repetition key 127 may be sequentially pressed to implement the input.

) 128, the " s " 125 key, and the repeat key 127 can be input sequentially.

Hereinafter, a method of inputting a vowel (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ) will be described with reference to <Table 2>.

collection Input key ㅏ "ㅏ" ㅑ "ㅏ" + "Repeat Key" ㅓ "ㅏ" + "ㅏ" ㅕ "ㅣ" + "ㅣ" ㅗ "ㅗ" ㅛ "ㅗ" + "Repeat Key" TT "ㅗ" + "ㅗ" ㅠ "ㅡ" + "ㅡ" ㅡ "ㅡ" ㅣ "ㅣ"

In Table 2, the vowels “ㅏ, ㅏ, ㅡ, ㅣ” are shown in FIG. 1 as “ㅏㅓ” (129) key, “ㅗ TT” (130) key, “ㅡ ㅠ” (131) key, and “ㅣ ㅕ”. It is possible to input by pressing the corresponding key to which the phoneme, such as the vowel, of the "132" key is assigned once. Four vowels of “ㅏ, ㅗ, ㅡ, ㅣ” are assigned to each of the vowels among the plurality of keys formed on the keypad 120 of the terminal, so that the vowels can be input by pressing the corresponding key only once. . On the other hand, the vowel of "ㅑ, ㅓ, ㅕ, ㅛ, TT, ㅠ" has no key assigned to be entered at a time, so the number of strokes to be entered must be two or more times.

In Table 2, the vowel “ㅑ” can be input by pressing the “ㅏㅓ” 129 key shown in FIG. 1 and then pressing the repeat key 127.

In Table 2, the vowel "ㅓ" can be input by pressing the "ㅏㅓ" 129 key shown in FIG. Since the "ㅏㅓ" 129 key is a key in which the vowel "ㅏ" and the vowel "ㅓ" are alternately inputted each time, the "ㅏㅓ" 129 key is preferably marked with "ㅏㅓ" on one key.

In Table 2, the vowel "ㅕ" can be input by pressing the "ㅕ" 132 key shown in FIG. Since the "ㅣ ㅕ" 132 key is a key that alternates the vowel "|" and the vowel "ㅕ" with each press, it is preferable to mark one key as "ㅣ ㅕ". In addition, another method of inputting the "ㅕ" may be implemented by pressing the "누른" (132) key twice in succession and then pressing the repeat key 127.

In Table 2, the vowel "ㅛ" may be input by pressing the "ㅗ TT" 130 key shown in FIG. 1 and then pressing the repetition key 127. In addition, in Table 2, the vowel "TT" may be input by pressing the "ㅗ TT" 130 key shown in FIG. 1 in succession twice. Since the "ㅗ TT" (130) key is a key to switch between the vowel "ㅗ" and the vowel "TT" alternately every time it is pressed, it is preferable to mark "ㅗ TT" on one key.

In Table 2, the vowel "?" Can be input by pressing the "-?" Key 131 shown in FIG. The ㅡ ㅠ (131) key is a vowel “ㅡ” and the vowel “ㅠ” are alternately switched each time it is pressed, so it is preferable to mark one key as “ㅡ”. In addition, another method of inputting the "ㅠ" may be implemented by pressing the "반복 tt" 130 key in succession twice and then pressing the repeat key 127.

As described above, in the embodiment according to the present invention, when the consonants and vowels excluding “3” are input, the number of strokes is 2 or less, thereby improving the Hangul input speed of the portable terminal. .

In particular, the keypad 120 including the keys made of the above arrangement provided in the embodiment according to the present invention has a high frequency of consonants "a", "b", "c", "ㅁ", "ㅅ" and "O" may input the six consonants with one input, and the consonants except the six consonants having a relatively low frequency of use may be input two or three times (mostly two times). This is to improve the consonant input speed by minimizing the number of inputs of high consonants.

The keypad 120 including the keys formed in the above arrangement may be used in portable terminals such as a portable telephone, a calculator, a PDA, an electronic organizer, and the device for inputting Korean characters may be applied to any apparatus.

Tables 3 and 4 show comparisons of strokes for the Korean input method and the conventional Korean input method in the present invention.

In Table 3, A represents the number of strokes for each consonant according to the present invention, B represents the number of strokes for each consonant according to the conventional cheonji method, and C represents the number of strokes according to the conventional naragle method for each consonant.

As shown in FIG. 3, the terminal includes a keypad 120, an input unit 300, a controller 310, a memory 320, an automata 330, a display unit 110, and the like. The controller 310 includes a consonant separator 310, and the memory 320 includes a consonant code table 321 and a program memory 322.

The consonant code table 321 included in the memory 320 stores codes for all consonants and vowels that can be input according to the present invention, and the program memory 322 provides various functions for the portable terminal 100. It stores the code programmed to do so.

)(128) 및 반복키(127)를 구비하여 형성되며, 상기 단말기(100)를 사용하는 사용자가 한글을 입력하기 위해 누를 수 있도록 상기 단말기(100)의 외부에 형성되어 있다.The keypad 120 may include a plurality of keys and special keys to which different consonants and vowels are assigned.

) And a repeating key 127 are formed outside the terminal 100 so that a user who uses the terminal 100 can press to input a Hangul.

When a predetermined key provided in the keypad 120 is pressed by the user of the terminal 100, the input unit 300 detects this and transmits an electric signal for the pressed key to the controller 310. The controller 310 includes a consonant separator 311, and the consonant separator 311 functions to classify the electrical signals received from the input unit 300 into initial, neutral, and final. In this case, the controller 310 matches the code pre-stored in the consonant code table 321 included in the memory 320 with a corresponding electrical signal received from the input unit 300, thereby receiving the received electrical signal. The consonants or vowels are classified and converted into codes corresponding to initial or neutral or final accordingly, and the codes are transmitted to the automata 330.

The automata 330 combines the received codes to generate a Korean code, and the Korean code is output as visible information through the display unit 110.

On the other hand, in the embodiment of the present invention has been described with respect to specific embodiments, various modifications are possible without departing from the scope of the invention. For example, it is obvious that the keypad may be used as a means for inputting conventional English. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below, but also by the equivalents of the claims.

According to the present invention, by efficiently classifying and assigning keys for inputting Korean consonants and keys for inputting vowels to a limited number of keys of a portable terminal, the user can input Korean characters with minimal key manipulation. The advantage is that speed can be improved.

In addition, the consonant with high frequency can be input in one stroke, and the low frequency consonant can be input in two or three strokes.

In addition, each key for inputting Hangul consonants is composed of a keypad including a key assigned only one of the six consonants (a, b, c, ㅁ, ㅅ, ㅇ), so that the keypad is visually simple It has the advantage of being expressed.
