Abstract

A method for inputting Korean characters in parallel by using a special key, a keypad and a mobile communication terminal therefor are provided to reduce a consonant inputting speed by two times at its maximum and a vowel inputting speed by three times at its maximum by using a concurrent pushing scheme of corresponding consonant or vowel keys and the special key in inputting Korean characters. A method for inputting Korean characters in parallel by using a special key comprises the following several steps. If a specified consonant key among plural consonant ones and the special key are pushed concurrently, a fortis of the first consonant between the first consonant and the second consonant allocated to the specified consonant key is outputted wherein the first consonant has a corresponding fortis and aspiration and the second consonant does not have a corresponding fortis or aspiration. If the specified consonant key and the special key are pushed continuously, an aspiration of the first consonant is outputted. If the specified consonant key is pushed repeatedly, the second consonant between the first consonant and the second consonant allocated to the specified consonant key is outputted.

The present invention relates to a Korean character parallel input method using a special key, a keypad and a mobile communication terminal therefor. More specifically, in inputting Hangul characters into a mobile communication terminal, the consonants are arranged in Hangul order in order to make it easier to remember the Hangul character composition of the pad and to speed up the input of Hangul characters. Create consonants and vowels, configure the keypad to visually recognize the vowels from the user's point of view, and input consonants and vowels simultaneously or consecutively, or consonants and vowels simultaneously or continuously The present invention relates to a method of inputting Korean characters by using simultaneous input and continuous input simultaneously by inputting a consonant or a vowel or a consonant or a composite vowel of a corresponding consonant, a keypad, and a mobile communication terminal therefor. .

As the use of mobile communication services becomes popular, mobile communication terminals have various additional functions. Although these additional functions are very diverse, one of them is a short message service function for inputting a simple sentence, a phone book function for inputting, storing, and retrieving a plurality of phone numbers for each user, and a schedule function. It is a function that uses the text input function to receive, output and save and transmit as needed.

On the other hand, since the mobile communication terminal is made compact for easy portability, a key input device that receives characters, that is, a keypad is also made compact, and the key buttons provided on the keypad are also limited to a few buttons. Typically, a keypad of a mobile communication terminal includes a function button for selecting a function, a numeric button for inputting a number such as a telephone number, and a character button for inputting a character such as Korean, English, or special characters. Here, the numeric button and the character button are typically configured to input one number and a plurality of characters in one key button.

Here, unlike English, which has a one-dimensional arrangement, Hangeul forms a single character by combining two-dimensionally, the first, the neutral, and the two-dimensionally, thus making the input method more complicated than English. Therefore, it has been required to develop a Hangul input method to simplify the process of inputting Hangul in a mobile communication terminal, and various Hangul input methods such as Cheonjiin and EZ (EZ) Hangul have been developed and widely used.

FIG. 1 is a diagram illustrating a configuration of a keypad for inputting Korean characters using Cheonjiin, which is a typical Korean input method.

A typical mobile communication terminal using Cheonjiin is provided with a total of 12 key buttons on the keypad as shown in the figure, and numbers or letters (English, Korean, special characters) are appropriately placed on the 12 keypads to display numbers or letters. Receive input.

In the case of Cheonjiin, as shown in Fig. 1, three Cheonjiin vowels ('ㅣ, ·, ㅡ') are assigned to the three key buttons at the top, and the six key buttons at the middle of two rows and the bottom Allocate consonants ('ㄱㅋ, ㄹ, ㄷㅌ, ㅂㄷ, ㅎㅎ, ㅈㅊ, ㅇㅁ') to one key button in the center, and assign special characters ('*, #') to the bottom left and right key buttons Press the key and the vowel key once or repeatedly to select and enter consonants and vowels.

Here, a total of 18 Hangul consonants are allocated to a total of seven numeric buttons, namely, 4, 5, 6, 7, 8, 9 and 0, that is, a key button on the middle of the keypad and the bottom of the keypad as shown in FIG. That is, the number button 4 has the letters 'ㄱ, ㅋ, ㄲ', the number button 5 has the letters 'b, ㄹ', the number button 6 has the letters 'ㄷ, ㅌ, ㄸ', and the number buttons 7 ', ,, ㅃ' character, '8', 'h' and '' 'in number button 8,' ',', '' in number button 9, '', '' in number button 0 Assign a character to

Table 1 shows a combination of key buttons for inputting consonants using Cheonjiin.

When the user inputs a consonant, as shown in Table 1, the user can select the desired consonant by pressing a specific number button once or three times. For example, 'ㄱ' is selected by pressing number button 4 once, 'ㅋ' is selected by pressing number button 4 twice, and 'ㄲ' is selected by pressing number button 4 three times.

As described above, using Cheonjiin, which is a conventional Hangul input method, in order to input a specific consonant, it is troublesome to press the number button to which the corresponding consonant is assigned two or more times up to three times. In other words, the consonants 'ㅋ, ㅌ, ,, ㅎ, ㅋ' need to press the number button twice, while the hard sounds 'ㄲ, ㄸ, ㅃ, ㅆ, ㅉ' need to press the number button three times, There is a problem that the speed is slow.

In addition, in the case of Cheonjiin, there is a problem in that consonant collision occurs because continuous input is impossible in case of the consonants assigned to the same key or the same consonant or the initial letter of the initial letter. For example, in case of entering 'Country', it is impossible to input continuously because the last letter of the first letter and the first letter of the last letter are 'A' and 'A'. 'Was forced to separate or wait for a preset time (for example, about 2 seconds) to continue typing characters.

The above-described problem of Cheonjiin, a conventional Korean input method, occurs not only in consonants but also in vowels. Hereinafter, a method of inputting a vowel using Cheonjiin will be described.

In the case of Cheonjiin, the vowels are assigned with 'ㅣ' to the number button 1, ' · ' to the number button 2 and '-' to the number button 3 as shown in FIG. Enter a vowel based on a combination of basic vowels ('ㅣ, ·, ㅡ').

Table 2 shows a combination of key buttons for inputting a vowel using Cheonjiin.

As shown in Table 2, 'ㅣ' is entered by pressing number button 1, 'ㅏ' is entered by pressing number button 1 and then number button 2, and 'ㅑ' is entered by pressing number button 1 Press twice in succession to enter. The remaining vowels are similarly entered. As described above, in the case of Cheonjiin, it is necessary to press the key button twice or three times according to the number of strokes of the vowels to be input, so that the selection of the desired vowels occurs and the input speed is slow.

On the other hand, as the Hangul input method, in addition to the above-described Cheonjiin, easy (EZ) Hangul is also widely used. In the case of Easy Hangul, 6 Hangul terminals ('ㄱ, ㄴ, ㄹ, ㅁ, ㅅ, ㅇ') are assigned to the consonant buttons, and 6 Hangul short vowels ('ㅏ, ㅓ, ㅗ) are input for Hangul short vowels. , TT, ㅣ, ㅡ ') and assign them to three vowel buttons. Consonant keys and consonants and vowels not assigned to vowel keys are consecutively combined with capture buttons (' * ') and consonant buttons and vowel buttons. Enter consonants and vowels.

However, similar to the above-mentioned Cheonjiin, easy Hangul also has a lot of consonants and vowels that are not entered at one time, so you have to press two or three key buttons to enter them, and many Hangul inputs are not displayed on the keypad. There is a problem that the learning time for learning is quite long. In addition, since the catch button ('*') and the consonant button ('#') must be frequently used, the fingering distance is long. Here, since easy Hangul is a widely used Hangul input method, a detailed description thereof will be omitted.

In order to solve this problem, the present invention, in inputting the Hangul characters into the mobile communication terminal, in order to make it easier to remember the Hangul character composition of the pad and to increase the input speed of the Hangul characters, according to the Hangul order Arrange and generate consonants and consonants according to Hangul characteristics, configure the keypad to visually recognize the vowels from the user's point of view, and input consonants and vowels simultaneously or consecutively, When inputted simultaneously or consecutively, the method of inputting Hangul characters by using simultaneous and continuous inputs simultaneously by recognizing the consonant or vowels of the consonants or the vowels or compound vowels of the vowels, the keypad and movement for them.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are designated as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

2 is a block diagram schematically illustrating a mobile communication terminal capable of inputting Korean characters in parallel using a special key according to an exemplary embodiment of the present invention.

A mobile communication terminal capable of inputting Korean characters in parallel using a special key according to an embodiment of the present invention includes a key input unit 210, an output unit 220, a memory unit 230, and a wireless communication processing unit 240. And a controller 250.

The key input unit 210 includes a key pad composed of a plurality of key buttons, detects a key input using the key pad, and converts the key input signal into a key input signal, which is an electrical signal, and transmits it to the controller 250. According to an exemplary embodiment of the present invention, the key input unit 210 may include five key buttons (hereinafter, referred to as 'b', 'b', 'c', 'd', '', ',', ',', ','). 4 key buttons (hereinafter referred to as 'vowel keys') to which a total of 4 basic vowels (left, right, lower, and upper) are assigned, and special keys are assigned. Key pad having one key button (hereinafter referred to as 'special key') and two key buttons (hereinafter referred to as 'special character key') to which a total of two special characters ('*, #') are assigned It converts the key input sensed using the keypad to a key input signal and delivers it.

The output unit 220 outputs various information such as letters, numbers, voices, and images under the control of the controller 250. The memory unit 130 is data storage means for storing a plurality of software required for operating the mobile communication terminal. When the memory unit 130 according to the preferred embodiment of the present invention is executed under the control of the control unit 250, the memory unit 130 analyzes a key input signal received from the key input unit 210 according to a predetermined algorithm to recognize and output a designated Korean character. A parallel Hangul input program, which is software output by using the unit 220, is stored.

The wireless communication processor 240 is a wireless communication means for providing a communication interface for the mobile communication terminal to perform wireless communication with a user terminal such as a mobile communication network or a computer that provides a mobile communication service.

The controller 250 is a control means that operates according to a key input signal input from the key input unit 510 to control the overall operation of the mobile communication terminal. The control unit 250 according to the preferred embodiment of the present invention, when the mobile communication terminal is switched to the Hangul input mode according to the user's key operation, and the key input signal is transmitted from the key input unit 210, parallel to the memory unit 230 The Hangul input program is executed to control the output unit 220 according to a predetermined algorithm of the parallel Hangul input program to output the input characters.

In this case, the parallel Hangul input program is a software for selecting and outputting a designated Hangul character according to a key input signal as described above. Unlike,, Hangeul, etc.), the state of pressing the special key is defined as a separate input state, so that the special key ('·') and the consonant key ('ㄱ, ㄷ, ㅂ, ㅅ, ㅈ') or vowel key (left) When ㅣ,, 하, ,, 상 'are input at the same time, each of the preset consonants (' ㅋ, ㅌ,, ㅎ, ') or a composite vowel (' ㅏ, ㅓ, ㅗ, ㅜ ') If the special key ('·') and the basic consonant key are sequentially input, it is recognized as the consonant sound ('ㄲ, ㄸ, ㅃ, ㅆ, ㅉ'). Here, when different basic vowel keys are input continuously, each basic vowel key is recognized as a synthesized vowel and output. For example, if 'left' and 'down' or 'up' are entered at the same time, 'ㅢ' is entered, and 'right' and 'down' or 'up' are entered simultaneously. Prints ㅢ '

In addition, the parallel Hangul input program is referred to as a consonant key ('ㄱ, ㅂ, ㅂ, ㅅ', hereinafter referred to as 'second consonant key') to which a second consonant ('b, ㄹ, ㅁ, ㅇ') of the basic consonant keys is assigned. ) Is input twice in succession, that is, if it is duplicated, it is recognized as the second consonant and is output. If different basic consonant keys ('ㄱ, ㄷ, ㅂ, ㅅ, ㅈ') are continuously inputted, If the combination is a compound consonant ('ㄳ, ㄵ, ㄶ, ㄺ, ㅄ') regardless of the order, it is recognized and output as the corresponding consonant, and if it is not the compound consonant, the first consonant of the basic consonant key is output continuously. . Here, the first consonant and the second consonant are consonants divided in the order of consonants assigned to each key button of the keypad, and the first consonants are five of the 'a, c, ㅂ, ㅅ, ㅈ' in the five key buttons. Dogs are assigned, and the second consonants are assigned four of 'a', 'c', 's' and 's' to the five key buttons, respectively. The first consonant and the second consonant will be described in detail with reference to FIG. 3.

In addition, a parallel Hangul input program has the same compound vowels ('ㅏ, ㅓ, ㅗ, ㅜ') inputted twice in succession, that is, duplicated inputs or compound vowels ('ㅏ, ㅓ, ㅗ, ㅜ') and special keys. In the case of continuous input, it is recognized as a double vowel ('ㅑ, ㅕ, ㅛ, ㅠ') of the corresponding compound vowel and outputs. ('Left' or 'Right') is recognized as a combination vowel ('ㅐ, ㅔ, ㅚ, ㅟ') that combines a compound vowel and its specific basic vowel, and outputs it. Combination of a combination of a specific vowel and a specific basic vowel when a specific vowel ('ㅑ, ㅕ') of the above-mentioned vowels and a specific basic vowel ('left' or 'right') of the basic vowels are continuously input. Print a vowel ('ㅒ, ㅖ'). The same rules apply when creating other collections.

Hereinafter, a configuration of a keypad for inputting consonants and vowels of Korean characters as described above with reference to FIG. 3 will be described.

3 is an exemplary diagram illustrating a keypad of a mobile communication terminal that can input Korean characters in parallel using a special key according to an embodiment of the present invention.

The keypad 302 according to the preferred embodiment of the present invention has five consonant keys 304 assigned with a total of nine basic consonants' ′, b, c, d, d, k, k, m, o, r. 306, 308, 310, 314), four vowel keys (312, 316, 318, 320) assigned a total of four basic vowels ('left', 'right', 'low', 'up'), and a special key One special key 318 and two special character keys assigned with a total of two special characters ('*, #').

That is, in the ten number buttons (hereinafter referred to as' numeric keys') in which the numbers from 0 to 9 are assigned to ten key buttons among the total of 12 key buttons of the keypad 302, the consonant ' A, b ', consonants' c, d' in number key 2 (306), consonants' ㅂ, ㅁ 'in number key 3 (308), and consonants' ㅅ, ㅇ' in number key 4 (310) , Vowel 'up ㅡ' in number key 5 (312), consonant 'ㅈ' in number key 6 (314), vowel 'left' in number key 7 (316), special in number key 8 (318). The key '·' is assigned to the numeric key 9 (320), the vowel 'right', and the numeric key 0 (324) is assigned the vowel 'ha-' to represent Korean characters according to the combination of each numeric and special key. . Here, two consonants are assigned to the numeric keys 1, 2, 3, and 4 (304, 306, 308, and 310, respectively), and the first consonant, 'a, c, ㅂ, ㅅ' is the first consonant, The next consonant, 'b, d, ㅁ, ㅇ', is called the second consonant.

Hereinafter, a process of inputting specific Korean characters will be described with reference to FIGS. 4 and 5.

4 is an exemplary diagram showing a combination of key buttons and the number of key inputs for inputting consonants according to a preferred embodiment of the present invention.

4A shows a combination of key buttons for inputting terminal tones. As shown, the first consonant ('a, c,, ㅅ, ㅈ') only needs to input the key button (1, 2, 3, 4, 6) to which each first consonant is assigned once. For the consonants of one consonant ('ㅋ, ㅌ,, ㅎ, ㅋ'), enter the key button (1, 2, 3, 4, 6) and the special key ('·') assigned to the first consonant at the same time only once. For the second consonant ('b, ㄹ, ㅁ, ㅇ'), the key button (1, 2, 3, 4) to which the second consonant is assigned need only be inputted twice, and the second consonant ( 'ㄲ, ㄸ, ㅃ, ㅆ, ㅉ') only need to press the key button (1, 2, 3, 4, 6) to which the first consonant is assigned, and then enter the special key ('·') only two times in succession. .

This rule is possible in the case of the second consonant ('b, ㄹ, ㅁ, ㅇ') in Hangeul because there is no voicing or sounding. Accordingly, the first consonant with the horn and the horn may display the horn by pressing the corresponding numeric key and the special key at the same time, and display the horn by pressing the digit key and the special key consecutively. This reduces the number of times you need to press a numeric key. That is, the first consonant ('ㄱ,, ㅂ, ㅅ, ㅈ') and the vowel ('ㅋ, ㅌ,, ㅎ, ㅋ') only need to be entered once, and the second consonant ('b,, ㅁ) , ㅇ ') and hom (' ㄲ, ㄸ, ㅃ, ㅆ, ㅉ ') only need to be entered twice.

4B shows a key button combination and the number of inputs for inputting a consonant sound. By the above-described method it can be represented by the consonant ('ㄳ, ㅄ, ㄵ, ㄶ, ㄺ, ㄽ, ㄻ, ㄼ, ㄿ, ㅀ, ㄾ'). That is, for example, a double consonant of 'ㄳ' and 'ㅄ' is inputted by pressing the numeric keys 1 and 4 simultaneously or by pressing the numeric keys 3 and 4 simultaneously. After pressing consecutively, press numeric key 1 to input, and 'ㄿ' is entered by pressing numeric key 2 two times in succession and pressing numeric key 3 and numeric key 8 simultaneously.

As described above, according to the present invention, all consonants that can be expressed in Korean can be expressed by pressing the numeric key up to two times. This means that you should press up to three times in the common Hangul input method, Cheonjiin or Easy Hangul, all the phonemes ('ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅌ, ッ, ㅊ, ㅎ, ㄲ , 입력, ㅃ, ㅆ, ㅉ ') can improve the input speed. In addition, according to the present invention, as in the case of Cheonjiin can be expressed up to four times, but the four consonants can be expressed only four times to express only one ('ㄻ'), the remaining four consonants can be entered by pressing only three times. . On the other hand, in the case of Cheonjiin, various consonants such as 'ㄿ, ㅀ, ㄾ' are inputted by pressing the numeric key four times.

5 is an exemplary diagram illustrating a combination of key buttons and the number of key inputs for inputting a vowel according to a preferred embodiment of the present invention.

As shown, the basic vowel ('ㅣ, ㅡ') can be pressed once by pressing the number key (7 or 9) once (for 'ㅣ') or by pressing the number key (5 or 0) once (' ㅡ '),' ㅢ 'is a combination of numeric keys (7 or 9) and numeric keys (5 or 0) at the same time press once.

For a composite vowel or compound vowel ('ㅏ, ㅓ, ㅗ,, ㅑ, ㅕ, ㅛ, ㅠ, ㅐ, ㅔ, ㅚ, ㅟ, ㅙ, ㅒ, ㅖ, ㅘ, ㅝ, ㅞ'), the default vowel is assigned It is possible to express by pressing a number key (7, 9, 5 or 0) at the same time, or pressing in combination, or pressing in combination or in succession.

For example, in the case of 'ㅏ', pressing the numeric key 7 and the special key 8 at the same time can be expressed by pressing only once, and the double vowel '눌러' is generated by pressing the numeric key 7 and the special key 8 simultaneously. It can be expressed by pressing the special key 8 consecutively only two times. In addition, 'ㅐ' can be expressed by pressing 7 and special key 8 at the same time as described above to generate 'ㅏ' and then pressing the numeric key 9 only two times, and 'ㅒ' by pressing 7 and special key 8 simultaneously. By creating 'ㅏ' and pressing number key 9 and then pressing number key 9 again, it can be expressed by pressing 3 times. In addition to this, the remaining vowels can be expressed by pressing only once or three times as in the key combination shown in FIG.

In this way, a combination of the basic vowel and a special key is used to express another vowel, and the vowel that can be expressed in Korean can be expressed by combining the special key and the basic vowel again. This has the advantage of expressing all vowels by pressing only up to 3 times, unlike Cheonjiin who can express all vowels by pressing up to 4 times, which is a typical Korean input method. In addition to the maximum number of inputs that can represent a vowel, the maximum number of inputs that can represent each vowel can be reduced according to each vowel. For example, 'ㅘ' should be pressed four times in the case of Cheonjiin, but according to a preferred embodiment of the present invention can be expressed by pressing only two times, 'ㅐ, ㅚ, ㅟ' should be pressed three times in the case of Cheonjiin, but the preferred embodiment of the present invention According to the advantage that can be expressed only by pressing once.

6 is a flowchart illustrating a method of simultaneously inputting Korean consonants using a special key according to an exemplary embodiment of the present invention.

When the user manipulates the mobile communication terminal by inputting a key through the key input unit 210 to input the Hangul, the control unit 250 of the mobile communication terminal executes a parallel Hangul input program stored in the memory unit 230 to predetermined The Korean character is output by analyzing the key input signal input from the key input unit 210 according to the algorithm.

When the parallel Hangul input program is started, the Hangul input mode is set (S602) to determine whether a key is input from the key input unit 210, that is, whether the key button of the keypad 302 is pressed (S604), When the key button is pressed, it is checked whether the corresponding key button is a consonant key (S606).

As a result of checking in step S606, when the consonant key is not input and the vowel key is input, the mobile communication terminal outputs a preset vowel in consideration of simultaneous input, continuous input, duplicate input, and the like (S608). Unlike consonants, vowels are omitted here because the combination of the basic vowel and the special key and the rules for determining the vowel output based on whether they are input simultaneously or continuously. However, as described with reference to FIG. 5, a vowel can be input quickly by combining a numeric key and a special key.

When the mobile communication terminal checks in step S606 that the consonant key is input, it checks whether it is simultaneously inputted with other keys, that is, whether it is a simultaneous input (S610). In other words, it is determined whether a special key is input (S612), and when a special key is input, the first consonant, that is, the first consonant of the consonant key other than the special key, is output (S614), and the special key is input. If not, check whether there is a consonant of the corresponding consonants (S616), if there is a consonant consonant, output the corresponding consonant (S618), and if there is no corresponding consonant, proceed to step S604 to check whether a key is input again. do. That is, when different consonant keys are input at the same time, when the consonant keys are combined to form a single consonant, the corresponding consonant is output, and when one consonant is not formed (combined with the consonants, If there is no double consonant sound, it is regarded as wrong input and another key button is input.

On the other hand, if it is not a simultaneous input in step S608, the first consonant assigned to the key is output (S620), and it is checked whether the consonant key is re-input (S622). If the consonant key is not re-input, the mobile communication terminal waits for key input. If the consonant key is re-input, the mobile communication terminal continuously inputs the key. If it is a special key (i.e., that is, the consecutively pressed key is a special key), the first consonant of the preceding consonant, that is, the first consonant of the first consonant key which is not the special key, is output. S626). As a result of the check in step S624, if the consecutively input keys are not special keys, it is checked whether the same key is repeatedly input (S628), and if the same key is repeatedly input to the same key, that is, the consonant key. Check whether there is a second consonant (S630), and if there is a second consonant, output the second consonant (S632), and if there is no second consonant, output the first consonant of the preceding consonant twice ( S634). That is, if the consonant keys are continuously pressed but the keys consecutively pressed are not special keys, the same key is pressed. If the corresponding consonants have a second consonant, the second consonant is output, and there is no second consonant. Outputs the same consonant twice.

In addition, when different consonant keys are sequentially pressed instead of duplicate inputs in step S628, whether there is a consonant consonant corresponding to the combination of the consonants is checked (S636), and if there is a consonant consonant corresponding to the combination of the consonants If the consonant has no consonant, the first consonant of the preceding consonant and the first consonant of the next consonant are output (S640).

7 is an exemplary view showing a keypad of a mobile communication terminal that can input Korean characters in parallel using a cross-shaped special key according to an embodiment of the present invention.

As described with reference to FIG. 3, a keypad of a mobile communication terminal according to an embodiment of the present invention includes four vowel keys representing basic vowels, five consonant keys representing basic consonants, and one special key. The three special keys may be represented by '·' as shown in FIG. 3, but the center is cut off at a predetermined radius in the crosshairs shown in FIG. 7 so that a user may easily understand the principle of composing a composite vowel as a basic vowel. It is preferable to represent it by the cross-shaped special key 710 which is a symbol which is issued.

That is, in the keypad 302, a key button indicating a basic vowel, that is, a vowel key is 'up' (312), 'left' (316), 'right' (320), 'down' (324). Since it is arranged in four rooms, east, west, north, and south, the cross-shaped special key 710 is located at the center of the four vowel keys, and is displayed as a cross-type (actually, as if the center of the cross-shaped diagram is cut out at a certain radius). By being recognized by the user in the form, it is easy to associate 'ㅗ', 'TT', 'ㅏ' and 'ㅓ' respectively. Therefore, the user can easily know that the numeric key 7 and the special key 8 must be pressed in order to input 'ㅏ'.

In addition, using the cross-shaped special key 710 in the case of consonants as well as vowels as described above, it is possible for the user to easily associate which key to press in order to compose a sound or a sound. That is, the cross-shaped special key 710 has a shape that seems to spread light in all directions, reminiscent of flickering. Therefore, the user can easily recognize that a consonant key and a cross-shaped special key indicating blinking must be combined in order to input a horn or a horn.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention but to describe the present invention, and the scope of the technical spirit of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, the Korean input speed can be shortened by up to two circuits in the case of consonants (except in the case of double consonants) and up to three circuits in the case of vowels using a special key and a simultaneous input method.

In addition, since the basic consonants are arranged according to the Hangul order and the sound consonants and the consonants of the basic consonants are generated according to the Hangul characteristics, the user can more easily remember the keypad configuration. That is, in the case of consonants, a consonant without a horn and a horn is separated into a second consonant so that only one horn and a horn are assigned to one key button so that the key button can be used efficiently.

In addition, by dividing the collection into four basic collections and placing them all around the keypad, and by placing special keys in the center of the keys for the four basic collections, the user can visually easily recognize the position of the keypad to construct the collection. have.

In addition, by defining a special key by dividing it into continuous input and simultaneous input, the consonant consonants are used to distinguish between the consonants and the consonants, and in the case of vowels, to generate a consonant vowel. It's easy to see how.

In addition, by connecting the special key with the basic vowels arranged on the top, bottom, left, and right, it is easy to associate the composite vowels so that the user can easily create the vowels. You can easily recognize that you need to use a special key.
