Hangul input device and method using number keys

The present invention relates to a Hangul input using a Ten Key in an electronic device, and in particular, Hangul is input through a minimum configuration of a letter without scrolling a key input table corresponding to one numeric key input provided in the electronic device. It is about how to.

In general, wireless telephones, wired telephones, and facsimile have become smaller. Therefore, since the telephone cannot be provided with many keys, it is difficult to provide a separate key as an input means for storing the caller's name and the like when setting up the automatic dial. In addition, when the user is provided with a large number of keys in the small electronic device is difficult when the user presses the key. Therefore, in the case of inputting Hangul in the small electronic device as described above, a character is read and displayed corresponding to the number of times of input of the numeric keys. If the table at the time of inputting Hangul using the numeric keys in the electronic device can be shown as Table 1 below.

TABLE 1

As shown in Table 1, when the electronic device proceeds to the Hangul input mode, consonants and vowels of different Hangul characters are input according to the number of times the user inputs the numeric keys. For example, if you input “Korean input is easy”, the user inputs '55611, 1 * 2, 33 ** 222, 2771, 33 * 11, 39 * 222, 1116' according to the table above. Each character entry requires a procedure to confirm the correct entry. In addition, the input method has a disadvantage in that it is difficult for a user to recognize because it does not have an association between numbers and letters. Therefore, a user who uses an electronic device that needs to input Korean by using a numeric key such as a telephone or a facsimile has a tendency to avoid Korean input and has inconvenience in inputting Korean.

Accordingly, an object of the present invention is to provide an apparatus and method for inputting using the minimum consonants and vowels of Korean characters when inputting Korean characters using a numeric key in an electronic device.

Another object of the present invention is to provide an apparatus and method for synthesizing and inputting consonants and vowels expressed in the input of Hangul into a combination of a set minimum consonant and a vowel.

In order to achieve the above objects, the present invention provides at least twelve keys provided in an electronic device, 'a', 'b', 'c', 'ㅂ', 'ㅅ', 'o', 't', ' ㆍ It consists of nine keys that input and combine consonants in one-to-one correspondence with ','-'and three keys that input and combine vowels in one-to-one correspondence with' ㅡ ',' ㅣ ',' · ' Completing and inputting Hangul, it is characterized in that the device is configured to further include a separate key for inputting distinguishing the last syllable of the last syllable and the first syllable when two or more syllables are connected to one input.

The present invention for achieving the above object is one-to-one correspondence with 'a', 'b', 'c', 'ㅂ', 'ㅅ', 'ㅇ', 'p', '·', '-' A Hangul input method of an electronic device having nine keys for inputting and combining a key and three keys for inputting and combining a vowel in a one-to-one correspondence with 'ㅡ', 'ㅣ', '·' In the input mode, the consonant input is input as the consonant input key for inputting each of the set consonants, and when the combination of the consonants is input consecutively by the input key of 'a' and the input key of 'c', 'ㄹ' When the input key of '-' and the input key of '-' are consecutively inputted, the combination of '-', the input key of '·', the input key of '-' and the ' When the input keys of ㅅ 'are consecutively inputted, they are combined into the letter' z ', and the input key and the When the input key of "a" is continuously inputted, it is combined into "ㅋ", and when the input key of "*" and the input key of "c" is inputted continuously, it is combined by "ㅌ", When the input key of '-' and the input key of '-' are continuously inputted, the consonant is inputted by combining 'ㅎ', the input of the vowel inputs the basic vowel with the input key of the set vowel, and the combination of the vowel is When the input key of 'ㅣ' and the input key of '·' are continuously inputted, they are combined into 'ㅏ', the input key of 'ㅣ', the input key of '·' and the input key of '·' Is combined with 'ㅑ' when continuously input, and when the input key of '·' and the input key of 'ㅣ' are continuously input, it is combined with 'ㅓ', and the input key of '·' and ' 'And the input key of' ㅣ ' When the input key of the 'Shinger' · 'and the input key of the'-'are consecutively inputted, the combination is' ㅗ', and the '·' input key and the '·' When the input key and the input key of '-' are continuously inputted, they are combined into 'ㅛ', and when the input key of '-' and the input key of '·' are continuously input, they are combined into 'TT'. When the input key of '-', the input key of '·' and the input key of '·' are consecutively inputted, the Korean consonants and vowels are input and combined by combining with 'ㅠ', The input method is performed through the consonant input and the consonant combination, and the input method of the composite vowel is composed of a Korean input method using a numeric key that can further input a complex consonant and a composite vowel through the vowel input and the vowel combination. It is characterized by.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The controller 111 controls the overall operation of the phone, and in particular, performs control when inputting Korean characters using the numeric keys according to the present invention. The Line Interface Unit (LIU) 112 is connected to a telephone station or an equivalent switch, and the user connects a line when the user hooks off the Hand Set 113 or dials using a speaker under the control of the control unit 111. Block it. The ringer unit 114 receives and outputs ringing tones received from the line interface 112 to notify the user of a call or outputs ringback tones received from the line interface 112 when dialing through a speaker. The memory unit 113 comprises a memory for storing data necessary for the control operation of the control unit 111 and a memory for temporarily storing the data generated during the control, in particular, the Hangul consonants according to the input of the number in accordance with the present invention In case of auto dialing setting, it saves auto dialing key, phone number and Korean name. The display unit 116 displays the state of the phone under the control of the control unit 111 or displays the Hangul in response to a key input when the Hangul is input according to the present invention. The key input unit 117 generates a key input signal in response to a key pressed by the user and outputs the generated key input signal to the controller 111. In addition, the key input unit 117 has a key matrix structure, and is composed of 3 × 4 numeric keys for dialing and function keys that require shortcut keys and settings required for automatic dialing.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 2.

The control unit 111 maintains the standby state in step 200 and checks whether an automatic dial input request signal is received from the key input unit 117. When the automatic dial input request signal is received as a result of the test, the controller 111 proceeds to step 204 and displays an automatic dial key selection request message on the display unit 116. The controller 111 proceeds to step 206 to determine whether an automatic dial key is selected. In step 206 to step 222, if the auto dial key is not selected for a predetermined time, the control unit 111 ends. If the auto dial key is selected, the control unit 111 proceeds to step 208 and displays a telephone number input request message on the display unit 116. The controller 111 receives a phone number in response to a key input signal received from the key input unit 117 in step 210. In this case, the control unit 111 recognizes the key input signal received from the 3 × 4 key matrix of the key input unit 117 as a numeric key and does not recognize the character input according to the present invention.

The control unit 111 receives the telephone number in step 210 and checks whether a confirmation key is input in step 212. When the check result confirmation key is input, the controller 111 proceeds to step 214 and outputs an input message of a Hangul name to the display unit 116. In step 216, the control unit 111 inputs Hangul in response to an input of a numeric key having a 3 × 4 matrix structure of the key input unit 117. In this case, a basic alphabet of Korean inputted in correspondence with the numeric key is shown in FIG. 3.

3 is a diagram showing a Hangul minimum alphabet of a 3 × 4 numeric key matrix according to the present invention.

As shown in FIG. 3, when the numeric key 1 is input 'ㄱ', the numeric key 2 is input 'b', the numeric key 3 is combined as a first consonant to complete a letter '·', If you enter the number 4, 'ㄷ', if you enter the number 5, 'ㅂ', the number 6 is the second consonant to complete the letter by combining it with the consonant '―', the number key 7 is' '', The numeric key 8 is composed of 'ㅇ', the numeric key 9 is composed of 'ㅅ', the numeric key 0 consists of '·' to complete the vowel, the asterisk key * is composed of 'ㅣ', and the wells pavilion key 'ㅡ'. Here, the numeric keys 3 and 6 are used for the synthesis of consonants, and the numeric keys 0 are used for the synthesis of vowels. In addition, the completion of letters may be output to the controller 111 using the confirmation key of the key input unit.

If the consonants and vowels of the Hangul correspond to the numeric keys, they can be shown in Table 2 below.

TABLE 2

As shown in Table 2, consonants can be synthesized using the Korean consonants 1 to 9 keys. In addition to the consonants shown above, a compound consonant 'ㄲ', 'ㄳ', 'ㄵ', 'ㄶ', 'ㄸ', 'ㄺ', 'ㄻ', 'ㄼ', 'ㄽ', 'ㄾ', ' It can be seen that consonants such as 'ㄿ', 'ㅀ', 'ㅃ', 'ㅄ', 'ㅆ', and 'ㅉ' can also be synthesized using the numeric keys 1-9.

Next, when the input of the vowels of Hangul is shown as a table, it can be shown as Table 3 below.

TABLE 3

As shown in Table 3, the basic vowel can be implemented using the 0 key, the # key, and the * key. In addition, a collection of compound collections 'ㅐ', 'ㅒ', 'ㅔ', 'ㅖ', 'ㅘ', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅢ' It can also be input using the method shown in Table 3.

In addition, when the user wants to input 'sit' during the input, the control unit 111 may be configured to display such as 'anja'. In this case, for correct notation of 'sit', the confirmation key can be entered once to distinguish between the finality and the initiality of the Hangul input. When the input of the Hangul is finished, the confirmation key is input by adjusting the number of times or time. It may be configured differently from the confirmation key for distinguishing the letters. In addition, it may be configured with a separate key to distinguish between the final and the initial of the letter.

On the other hand, the control unit 111 receives the Hangul name and displays the Hangul in step 216. In addition, the control unit 111 proceeds to step 218 to check whether a confirmation key is input. The control unit 111 proceeds to step 220 when the confirmation key is input in the method set as a result of the test, and stores the telephone number and the Hangul name in correspondence with the automatic dial key selected in step 206.

The above has been described with an example of setting up an automatic dialing in a telephone mainly using numeric keys, but this is not limited to the telephone and can be used when inputting Hangul into all electronic devices having a numeric key of 3 × 4.

As described above, it is possible to input Hangul by operating only 0 to 9 keys, and the Hangul input process has the advantage of combining characters without scrolling the table for displaying and storing when one key is continuously input. . In addition, the input of Hangul is the same as the process of writing letters, so it is convenient to use.
