The present invention is for inputting Korean characters using a small keypad included in a telephone or a remote control. More specifically, it provides a basic handwriting character input method that can input Korean phonemes by handwriting using only one finger, and a short form input method that reduces the number of key button presses, and selects a user's desired input method. The Korean input device is configured to use.

Recently, due to the popularization of mobile phone terminals and the emergence of new media such as Internet TV, character input is also performed through a keypad (for example, a keypad for numeric input) which has reduced key button numbers much more than conventional character input devices such as computer keyboards. There was a demand for it to be possible. In order to meet these demands, various input methods have been proposed in the related art, in which Korean characters are inputted in particular through a small keypad. Examples of such conventional Hangul alphabet input method, Korean patent registration number 10-0201211 (registration date March 12, 1999, patent holder Jo Kwan-hyun) "Korean code input device of a compact keyboard" and Korea Patent Registration No. 10 -0291839 (Registration date March 16, 2001, the patent holder is a language science Co., Ltd.) "Hangul input device and method based on the principle of Cheonjiin disciple". These two technologies are also the text input method currently employed in domestic mobile phones.

1A and 1B show a keypad of a current mobile phone employing the two conventional techniques. The keypad 10 illustrated in (a) of FIG. 1 is an example of adopting a so-called 'Cheonjiin' vowel input method disclosed in the registration publication of Jo Kwan-hyun's "Hangul code input device of a compact keyboard". The illustrated keypad 10 has a vowel input area 12 for vowel input and a multi-tap consonant input area 14 for consonant input. In the case of consonants, for example, pressing the number button 4 once a is input, pressing twice is the input ㅋ, and pressing the input 3 times is a multi-tap method in which the character is input. In the case of vowel, character input is performed according to a certain drawing rule by using only three buttons which are allocated by simplifying the shape of the vowel stroke into ㅣ, ㅡ, ·. In this way, three buttons for vowel input can be configured. Accordingly, in particular, it is widely used in a mobile phone that must input both consonants and vowels using a numeric keypad including 12 key buttons. However, in the vowel input method of the present invention, since there are three vowels that can be input by one button, there is an inconvenience in that the number of key button presses increases in response to the number of strokes of the vowel in the other vowels.

Meanwhile, the keypad 20 illustrated in (b) of FIG. 1 is disclosed in the registration publication of "Hangul input device and method based on the Cheonjiin Disciples Principle" of Linguistic Science Co., Ltd. Hangul input method, which is called 'method, is applied. The illustrated keypad 20 has a basic consonant / vowel input area and an area for plotting and writing for the 'basic-grasp-dose' scheme. Specifically, the keypad 20 includes a basic vowel input area 22 consisting of four buttons, a basic consonant input area 26 consisting of six buttons, and a complex double vowel or horn which is not present in the basic input areas 22 and 26. An additional tab area 28 is provided to allow input of the same character. In the 'basic-capture-dose' approach of linguistic science, each number button is assigned some basic phonemes of consonants or vowels as fixed as possible. Phonemes that are not the default phonemes, such as unassigned listening, voicing, horning, and other vowels, can be entered by pressing the * button or the # button more than once, once the default phoneme has been entered.

In the conventional text input method using the small keypad, there is no correlation between the actual written form of the consonant or the vowel and the position of the key button pressed. Therefore, the user had to memorize consonants or vowels corresponding to the respective numeric key buttons, and in the case of not being able to memorize, the user was forced to enter a character while viewing the marking printed on the surface of each numeric key button.

Accordingly, similarly to a writing method that a user is already familiar with, an input method for easily inputting with one finger has been proposed. In this 'handwritten' input method. Such methods are disclosed, for example, in Korean Patent Application No. 1994-0035027 of LG Electronics Co., Ltd., Korean Patent Application No. 2002-0000126 of Son Mira, and Korean Patent Application No. 2002-0072567 of Kim Kuk-hwan. . Such a handwriting input method has proposed a method of inputting a corresponding character by sequentially inputting a plurality of buttons arranged adjacently according to the handwriting form of a character to be input using a numeric keypad, but its practicality is questionable. there was. Accordingly, according to Korean Patent Application No. 10-2003-0013754 (Applicant Song Woo-chan, filed March 5, 2003), "Korean input device using a numeric keypad and its input method", such a conventional simple handwriting input method A handwritten Hangul input method has been proposed.

In the improved handwriting input method, as an example is illustrated in FIG. 2, in the consonant input, a method of inputting audible sound (a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ) It is divided into a method of inputting a vowel and a vowel sound (ㅋ, ㅌ, ㅍ, ㅎ) and a method of inputting the rhythm (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) and has the characteristic of being input by handwriting. Specifically, first, the hearing is input using the listening input area including key buttons arranged in four squares. In actual input, the key buttons in the listening input area are sequentially pressed in an input pattern similar to the handwritten form of the hearing to be input. The sound is input through a sound input area in which two key buttons of the sound input area and two key buttons adjacent to the sound input area are arranged in a square. The input pattern of the vowel is substantially the same as the input pattern of similar hearing. For example, the input pattern for listening 'a' and the input pattern for 'bee' are the same type, but only the input area is different. The horn is input in the horn input area, and the horn is input by pressing a key button for horn once more. For example, in order to input the rhythm 'ㄲ', a pattern for inputting the vowel 'ㅋ' is drawn and then the horn key button is pressed once more. In the case of a vowel, as illustrated in FIGS. 4 and 5, the vowel is input through a vowel input area including five key buttons arranged in a cross form based on the vowel form.

In this method, although the number of key buttons to be input can be increased, the user can easily enter text because the text input can be made by drawing gold on a plurality of buttons as if drawing with one finger or fingernail. It has the advantage of being able to. Furthermore, this method is close to the actual writing method, and it is easy to input all the Hangul alphabets by simply applying additional rules. Therefore, it can be easily used by young people as well as middle-aged people. However, in the case where the shape of the key button is inconvenient to press several key buttons in sequence as if the finger is cracked with a fingernail (for example, when the height of the key button is high or large), the number of times of actually inputting the key button is high. Character input is difficult.

Therefore, there has been a technical demand for a new method that can reduce the number of key button inputs while using a handwriting method.

It is an object of the present invention to provide a Korean input device using a small keypad having a shortened handwriting input method that can reduce the number of key button inputs while being able to use the improved handwriting method as described above.

Another object of the present invention is to provide a Korean input device using a small keypad having various handwriting input methods that allow a user to select from a basic handwriting input method or a shortened handwriting input method.

In order to achieve these objects, according to one aspect of the present invention, an apparatus for inputting Korean using a small keypad is provided. The apparatus includes: a keypad configured with a plurality of key buttons arranged to identify six key button areas arranged in a rectangular shape and five key button areas arranged in a cross shape; At least one key button signal generated by each key button of the keypad includes at least one consonant-key list corresponding to one phoneme of Hangul consonants and one phoneme of Hangul vowels. A memory storing one or more vowel-key lists; And generate a temporary key sequence each time a key button signal generated by the key button of the keypad is input, search for and extract a phoneme corresponding to the temporary key sequence from the phoneme-key list, and extract the extracted phonemes into Korean syllables. It is configured to include a control unit for controlling to combine according to the combination rule.

Herein, the control unit allows the user to select a consonant and vowel input mode, in which case the user selects a consonant input mode by selecting one of the one or more consonant-key lists, and the one or more vowel-key lists. You can select the vowel input mode by selecting one.

According to a preferred embodiment of the present invention, the one or more consonant-key lists include: six key button regions arranged in the rectangular form are sequentially divided into a sound input region and a vowel / horn input region to write a predetermined character. A basic consonant-key list in which a predetermined consonant corresponds to a predetermined key sequence including one or more input key button signals; And an abbreviated consonant-key list corresponding to consonants in a shortcut key sequence including only a key button signal of a part of key button signals constituting a key sequence of the basic consonant-key list.

According to a preferred embodiment of the present invention, the one or more vowel-key lists include: one or more key button signals sequentially inputted in a manner of writing a predetermined character in the five key button areas arranged in the cross shape. A basic vowel-key list in which a predetermined vowel corresponds to a predetermined key sequence; A shortcut type vowel-key list in which a vowel corresponds to a shortcut key sequence including only a key button signal of a part of the key button signals constituting the key sequence of the basic consonant-key list; And a four-button shortening inputted from four key button regions except for a central key button among the five key button regions arranged in the cross shape and including only a key button signal of a part of the key button signals constituting the shortcut key sequence. The key sequence may include a four-button shortcut vowel-key list to which the vowel corresponds.

According to the present invention, a Korean input device may be provided in which any one of the above-described handwritten basic type or shortened consonant input method is combined with one of the conventional vowel input methods, that is, a assorted input method such as a celestial vowel input method.

According to a specific embodiment of the present invention, the keypad is preferably a keypad for numeric input including an arrangement of three horizontal x four vertical key buttons (1 to 9, 0, *, #). According to another specific embodiment, the keypad includes three horizontal × four vertical (1-9,0, *, #) key button arrangements for entering numbers, and five front, rear, left, right, and center key buttons for indicating directions. (→ ← ↑ ↓ ◎) may be a keypad including key buttons arranged in a cross shape.

According to the present invention, a Korean input device using a small keypad having a shortened handwriting input method capable of reducing the number of key button inputs while being able to use a conventional improved handwriting method can be provided.

In addition, according to the present invention, a Korean input device using a small keypad having various handwriting input methods for allowing a user to select from a basic handwriting input method or a shortened handwriting input method may be provided.

The configuration and operation of the present invention as described above, will be clearly understood by the detailed description made through the specific embodiments of the present invention with reference to the accompanying drawings.

The Korean input device according to the present invention includes a keypad including a plurality of buttons, a controller for receiving and processing a signal input through the keypad and outputting the processed input signal as a character (phoneme, syllable) representation, and a keypad. It may include a memory for storing data such as, for example, look-up table having a predetermined rule for matching the input key button signal to the character. The processing unit may be connected to devices for further processing, such as an LCD display device or a speaker or a data transmission unit provided in the mobile phone. Such an input device may be applied as a small keypad implemented in a small electronic device, such as a mobile phone or a PDA. Furthermore, it can be applied as a small keypad implemented in a remote control for remotely controlling the operation of home appliances such as a TV.

In the Korean input device according to the present invention, the user sequentially presses the key buttons according to a predetermined pattern described in detail below, that is, an input pattern similar to a handwritten form of a character to be input. More preferably, the user " writes " like drawing gold over a plurality of key buttons with one finger in accordance with the input pattern.

In this way, each key button pressed when the user "writes" generates a corresponding key button signal. The control unit receives the key button signal and generates a key sequence consisting of the received key button signal. Thereafter, the controller may retrieve a phoneme-key list stored in the memory and extract a phoneme corresponding to the generated key sequence. The extracted phonemes may then be combined according to Korean's consonant, neutral, and final combination rules. The phoneme extraction process, as described in Korean Patent Application No. 10-2003-0013754 filed by the applicant can be applied as it is. Therefore, for the sake of simplicity, the detailed description of the phoneme extraction process will not be given herein.

2 and 3 illustrate a basic type and a short form of a Korean consonant handwriting input method applied to a numeric keypad having a 3 × 4 key button arrangement according to an embodiment of the present invention.

As can be seen, only six rectangular key button arrangements are required for the handwritten consonant input according to the present invention, both basic type (FIG. 2) and short form (FIG. 3). The consonant input area is divided into a listening area and a horn / horn area. Specifically, the listening-only input area for inputting only the listening expressions (a, b, c, r, ㅁ, ㅂ, ㅅ, ㅈ, ㅇ) may consist of four square key buttons. In the example shown, it can be seen that the listening only input area consists of 1,2,4,5 numeric buttons. It can be seen that the area for inputting the vowel sound (vo, ㅌ, ㅌ, ,, ㅎ) and the horn (ㄲ, ㄸ, ㅃ, ㅉ, ㅆ) also consists of four square key buttons.

In the handwritten consonant input method according to the present invention, since the consonant input area is separated in this way, it provides an advantage of allowing the user to input the sound between the sound and the hard sound according to the rule as simple as possible.

According to the present invention, when a character is input, the user may sequentially press key button patterns arranged similarly to the handwritten form of the character. In other words, you can "write" the character pattern with one finger as if you were drawing gold.

As illustrated in FIG. 2, in the basic handwritten consonant input method, for example, the user inputs 1, 2, 5 key buttons to input the listening sound "a". In this case, since each key button is arranged in the form of "a", the user can press the corresponding key buttons arranged in the form of a handwritten character of "a" as if one finger draws gold. On the other hand, in the case of entering the beep "ㅋ", the user, in the same pattern as in the case of entering "ac" which is audible, but in the other input area, the key buttons arranged in the form of "a", that is, 2, 3, 6 Press the key button. And if the user wants to enter the horn "ㄲ", the user inputs the vowel "ㅋ" and presses another additional key button for the horn. That is, in the example shown, press 2, 3, 6 and press the 6 key button, which is a key button for sound.

The shorthand handwritten consonant input method as illustrated in FIG. 3 is similar to the basic handwritten consonant input method described above, except that the input pattern is shortened as compared with the basic type. According to this short form, it is obvious that the number of key button inputs can be greatly reduced. However, in the shortened form, since it is not similar to the handwritten form of the input character, it is preferable that a person skilled in the handwritten form shown in FIG. 2 select and use it. According to this short form, the user inputs 1, 2 key buttons, for example, in order to input the listening sound "a". In this case, since each key button is a form of shortening 1,2,5 key buttons for inputting the basic type "a", it can be expected that a person who is familiar with the basic type input method can use this short form more easily. On the other hand, in the case of entering the beep "k", the user presses the abbreviated key buttons, i.e., the 2,3 key button, in the same pattern as in the case of entering the "a" which is the acoustic sound but in another input area. And if the user wants to enter the horn "ㄲ", the user inputs the vowel "ㅋ" and presses another additional key button for the horn. That is, in the illustrated example, 2 and 3 are pressed and 6 key buttons, which are the key buttons for the sound, are pressed.

In the consonant input method according to the present invention described above with reference to FIGS. 2 and 3, the key sequence consisting of key button signals corresponding to the input consonant phoneme is summarized in Table 1 below. This table may be stored in the memory as a 'phone-key list' and used by the controller when phoneme extraction. Each number constituting the key sequence in the table represents a key button signal generated by the key button for inputting the corresponding number. It is to be understood that Table 1 is presented here by way of illustration for illustrative purposes and is not intended to limit the invention to the examples listed.

phoneme Basic Handwritten Key Sequences Shorthand Handwritten Key Sequences A 1-2-5 1-2 N 1-4-5 1-4 C 2-1-4-5 2-1 D 1-2-4-5 4-5 M 4-1-2-5 4-1 ㅂ 1-4-2-5 2-5 S 4-1-5 or 4-2-5 4-2 ㅇ 1-1 or 1-5 1-1 or 1-5 ㅈ 2-4-1-5 2-4 H 3-5-2-6 3-5 Lol 2-3-6 2-3 ㅌ 3-2-5-6 3-2 ㅍ 2-5-3-6 3-6 ㅎ 2-2 or 2-6 2-2 or 2-6 ㄲ (2-3-6) -6 (2-3) -6 ㄸ (3-2-5-6) -6 (3-2) -6 ㅃ (2-5-3-6) -6 (3-6) -6 ㅉ (3-5-2-6) -6 (3-5) -6 ㅆ 4-2-6 4-2-6

As described above, according to the shortened handwriting input method provided, since the number of times the key button is pressed can be minimized, the character input speed can be improved. In addition, since the shorthand input method is shortened from the basic handwritten input method, a user who has acquired the basic handwritten input method has an advantage of not requiring additional learning. Accordingly, it is possible to provide an environment in which the user can select the consonant input method step by step according to his or her character input proficiency.

Similar to the basic and short handwritten consonant input methods as described above, in the vowel input method, a shortened form is gradually defined from the form most similar to the handwritten form, and the user can select and use the text based on his / her proficiency level. It can be done.

Some examples according to the present invention that can be implemented in such a stepped vowel input scheme are shown in FIGS. 4 to 7. 4 shows a cross-type vowel input method as the simplest method, and FIG. 5 shows a 'medicine' vowel input method that is the simplest method as a handwriting form, and FIG. 7 illustrates an input method, and FIG. 7 illustrates a 'vowel' vowel input method that is the closest and most complicated method to the writing form.

The vowel input according to the present invention is characterized by using a key button area composed of five buttons in a cross-shaped arrangement, focusing on the shape of the vowels formed by straight lines of up, down, left and right. In the illustrated examples, in the keypad for numeric input having a 3 × 4 key button arrangement, an area consisting of 5, 7, 8, 9, and 0 key buttons forming a cross shape is used as a vowel input area. In addition, the vowel input method according to the present invention may be implemented using key buttons for indicating a direction, such as a remote controller or a game keypad.

4 illustrates a keyboard-type phoneme configuration, that is, a cross-array type vowel input method in which phonemes are assigned to key buttons of a vowel input area. The center key button (key button 8) similarly corresponds to the long horizontal and vertical strokes (━, ┃), and the up, down, left, and right key buttons (5, 0, 7, and 9 key buttons) are respectively vowels ( It can be comprised so that it may correspond to the form of ╇, 우, 어, 아, 아. In this method, for example, 'ㅏ' is a 9-key button for inputting the number 9, 'ㅓ' is a 7-key button, 'ㅗ' is a 5-key button, and 'TT' can be input by pressing the 0-key button once.

In this case, the user can easily input the vowel by inferring the position and shape of the vowel stroke number by the position of each key button. This method is also a vowel input method with fewer key button inputs in the vowel input method according to the present invention.

In the cross-array type input method, the key sequence consisting of key button signals corresponding to the input vowel phoneme is summarized in Table 2 below. This table may be stored in the memory as a 'phone-key list' and used by the controller when phoneme extraction. Each number constituting the key sequence in the table represents a key button signal generated by the key button for inputting the corresponding number. It is to be understood that Table 2 is presented here by way of illustration for illustrative purposes and is not intended to limit the invention to the examples listed.

phoneme Cross Keys Sequence ㅏ 9 ㅓ 7 ㅗ 5 TT 0 ㅘ 59 or 95 ㅝ 07 or 70 ㅡ 88 ㅐ 98 ㅔ 78 ㅚ 58 ㅟ 08 ㅙ 598 or 958 ㅞ 078 or 708 ㅣ 8 ㅑ 99 ㅕ 77 ㅛ 55 ㅠ 00 ㅒ 99-8 ㅖ 77-8 ㅢ 88-8

FIG. 5 shows an example of a stylus input method that is the simplest method as a writing form, that is, a stroke configuration closer to the writing method than the cross array type. In this method, the center key button (key button 8 in this example) corresponds to the long horizontal and vertical strokes (━, ┃), and the up, down, left, and right buttons (5, 0, 7, 9) ) Can be considered to be assigned to the upper, lower, left, and right sides of the cross, respectively. In this case, when inputting “ㅏ”, press the center key button and the right key button, that is, the 8 and 9 key buttons. At this time, even when pressing 9,8 can be set to input "ㅏ".

This correspondence between the key button and the stroke has the advantage that the user can easily infer the position of the key button even if it is not necessarily printed on the surface of the key button. Since the present method may be considered to be more similar to the cross-type handwriting type than the cross-type type and has a simple shape, it is referred to herein as a handwritten 'medical pen' method.

In this medicine-type input method, a key sequence consisting of key button signals corresponding to an input vowel phoneme is summarized in Table 3 below. This table may be stored in the memory as a 'phone-key list' and used by the controller when phoneme extraction. Each number constituting the key sequence in the table represents a key button signal generated by the key button for inputting the corresponding number. It is to be understood that Table 3 is presented here by way of illustration for illustrative purposes and is not intended to limit the invention to the examples listed.

phoneme Handwritten Key Sequence ㅏ 89 or 98 ㅓ 78 or 87 ㅗ 58 or 85 TT 08 or 80 ㅘ 589 or 985 or 58-89 or 85-89 or 85-98 ㅝ 087 or 780 or 08-87 or 80-78 or 80-87 ㅡ 88 ㅐ 89-8 or 98-8 ㅔ 78-8 or 87-8 ㅚ 58-8 or 85-8 ㅟ 08-0 or 80-8 ㅙ 589-8 or 985-8 or 58-89-8 or 85-89-8 or 85-98-8 ㅞ 087-8 or 780-8 or 08-87-8 or 80-78-8 or 80-87-8 ㅣ 8 ㅑ 998 or 899 or 889 ㅕ 778 or 877 or 887 ㅛ 558 or 855 or 885 ㅠ 008 or 800 or 880 ㅒ 998-8 or 899-8 or 889-8 ㅖ 778-8 or 877-8 or 887-8 ㅢ 88-8

6 illustrates an example of a 'short' vowel input method that is an intermediate method in a handwritten form. In the shorthand vowel input method, only four key buttons of up, down, left and right are used except for the center key button among the key buttons of the cross-shaped array. For example, in the case of a 3x4 numeric keypad, a vowel may be input using only 5, 7, 9, and 0 buttons. In this case, there is no center button (e.g., button 8) corresponding to the long horizontal and vertical strokes of the vowel. Instead, the long horizontal stroke (━) can be entered by pressing the 7, 9 buttons (left and right buttons), and the long vertical stroke (┃) by pressing the 5,0 buttons (up and down buttons). In this case, when inputting "ㅏ", press the 5,0 key button as the upper and lower long strokes, and press the 9 key button as the stroke projecting to the right. In other words, press 5,0,9 key button to input 'ㅏ'.

When the vowel is input according to the present method, it can be seen that the user's finger is almost close to the 'ㅏ' writing form. Since the present method is shortened as compared to the writing method using the eight key buttons in the center below, it is referred to as a vowel input method of the 'single-type' method in the present specification.

In this short-cut input method, a key sequence consisting of key button signals corresponding to the input vowel phoneme is summarized in Table 4 below. This table may be stored in the memory as a 'phone-key list' and used by the controller when phoneme extraction. Each number constituting the key sequence in the table represents a key button signal generated by the key button for inputting the corresponding number. It should be noted that Table 4 is presented here by way of illustration for illustration and is not intended to limit the invention to the examples listed.

FIG. 7 shows an example of a 'writing' vowel input method that is the closest to the handwriting form and the most complicated method. The stylus-type vowel input method has a characteristic of inputting in a manner most similar to the vowel form by using all five key buttons constituting the cross button-shaped key buttons. For example, in the case of a 3 × 4 numeric keypad, the vowel may be input using the 5, 7, 8, 9, 0 key buttons.

When the vowel is input according to the present method, it can be seen that the user's finger is very close to the writing form of 'ㅏ'. Since the present method is the most complicated and most similar to the handwriting form compared to the other handwriting input methods described above, it is referred to herein as a vowel input method of the 'writing' method.

In such a pen-type input method, a key sequence consisting of key button signals corresponding to an input vowel phoneme is summarized in Table 5 below. This table may be stored in the memory as a 'phone-key list' and used by the controller when phoneme extraction. Each number constituting the key sequence in the table represents a key button signal generated by the key button for inputting the corresponding number. It is to be understood that Table 5 is presented here by way of illustration for illustration and is not intended to limit the invention to the examples listed.

The key sequence for each phoneme representation described above may correspond to all phonemes without overlapping. This is possible because the number of combining a plurality of buttons is larger than each phoneme of Korean, which is a character to be expressed.

FIG. 8 is a schematic diagram illustrating providing a user with an environment for allowing a user to select one of the basic and short input methods described above. What is shown may be added, for example, as an 'input mode configuration' function to a mobile phone. Conventional mobile phones have been defined as one type of consonant and vowel input methods, but according to the present invention, a complicated and easy-to-use handwritten basic type and a simple but short form that requires knowledge of the existing basic type should be premised according to the user's character input proficiency The advantage is that any one of them can be freely selected.

In the illustrated example, the user can select the handwritten basic type and the handwritten short form as the consonant input method, and optionally select the 5-button multi-tap consonant input method or the conventional basic-capture-parallel method as described above. have. As a vowel input method, the user may select any one of a handwritten handwriting, a handwritten shorthand, a handwritten medicine pen, or a cross-array type. In some cases, the user may select a method that is heaven and earth.

9 to 12 illustrate various types of input keypads according to the present invention. The keypad 30 shown in FIG. 9 uses the upper three key buttons as an area 32 for inputting a vowel in a celestial manner, and the six key buttons below the handwritten basic type according to the present invention. This is an example used as the short consonant input areas 34 and 36. According to another exemplary embodiment, the vowel region in heaven and earth may use 1, 4 and 7 key buttons, and the handwritten consonant region may use 2, 3, 5, 6, 8 and 9 key buttons. Other arrangements are also possible. The keypad 40 shown in FIG. 10 is an area 44 for consonant input of six key buttons in a three-by-four horizontally-vertical four-key (1-9,0, *, #) keybutton array for inputting numbers. In this example, the front, rear, left, right, and middle key buttons (→ ← ↑ ↓ ◎) for indicating the direction are used for the vowel input. The keypad 50 illustrated in FIG. 11 is an example having a vowel input area 52 having a cross-shaped arrangement and a 5-button multi-tap consonant input area 54. In addition, the keypad 60 shown in FIG. 12 is an example in which six key buttons are used as the handwritten consonant input areas 64 and 66 and a cross-shaped key button array is used as the vowel input area 62. to be.

Combining such various input methods can be easily accomplished by the input mode setting function shown in FIG. 8 according to the present invention. For those who frequently type letters and are proficient, the letters can be entered even if the letters are not printed on the surface of the key button. Therefore, the function of setting different input modes makes sense. In particular, the handwritten consonant / vowel input method according to the present invention is particularly suitable for application to such an input mode setting function since the user can easily infer the pattern of the corresponding input key button by the handwriting form of the character.

In the above, the Korean input device has been described as using a 3x4 numeric keypad having 12 buttons. However, it will be readily apparent to one skilled in the art that the present invention does not necessarily apply only to this twelve button numeric keypad. For example, it is also applicable to small keypads including up (↑), down (↓), left (←), right (→) arrow key arrangements and other at least 3 × 3 button arrangements, such as game pads.

In the above, the present invention has been described through a specific embodiment using a 12-button numeric keypad of a mobile phone or the like, or a key button configuration of a remote controller or a pad for a game machine, but the present invention is not limited to the described example. Character input is sufficient in all electronic devices having six rectangular key button arrangements and / or five cross key button arrangements, as well as small electronic devices such as remote controls, cellular phones and PDAs. For example, it may be applied as an input device for a wearable telephone or a computer keyboard having a wristwatch shape and size. As such, those skilled in the art can readily make various modifications, changes, and combinations within the technical scope of the appended claims and the technical scope represented by the various claims without departing from the spirit of the present invention. Therefore, it should be pointed out that the protection scope of the present invention should be limited only by the technical scope and the equivalent technical scope claimed in the claims.

The present invention as described above can provide a Korean input device using a small keypad having a shortened handwriting input method that can reduce the number of key button inputs while being able to use the conventional improved handwriting method. Furthermore, the present invention provides a remarkable effect, such as providing a Korean input device using a small keypad having various handwriting input methods for allowing a user to select from a basic handwriting input method or a shortened handwriting input method.
