The present invention relates to a Hangul input device and method, and more particularly, to a Hangul input device and method for inputting the Hangul through the keys assigned according to the shape of the consonants and vowels of the Hangul.

Hangul is the initial consonant of a Korean syllable, the vowels consonant of a Korean syllable It is divided into the initial final of a Korean syllable and has a writing system forming a syllable while being two-dimensionally arranged consisting of initial and neutral or initial, neutral, and final.

When entering characters, one-dimensional characters have a relatively simple character input system because a single word is completed by simply phoneme order and space, whereas Hangul not only has to be arranged two-dimensionally, When more than one consonant is repeated except for yi, such as, you have to decide how to place these consonants, and since you can basically have 14 consonants and almost infinite vowels, you can enter more complex characters. A system is required.

With the rapid development of electric and electronic technology, various kinds of electronic devices such as CDM, PCS, TDMA, GSM, AMPS, IMT-2000, etc., miniaturized electronic devices such as mobile phones, personal digital assistants (PDAs), pagers, small game consoles, remote controllers, cameras, etc. have. In addition, with the miniaturization of electronic devices, as functions are gradually improved, the necessity of inputting characters in electronic devices has emerged.

1 is a diagram illustrating a keypad of a portable communication device according to the related art. As shown, a keypad of a portable communication device according to the prior art is composed of function keys having special functions such as numeric keys # and * from 0 to 9, and the like. In addition, each key is arranged with consonants from 'ㄱ' to 'ㅎ', vowels and special characters designated by the manufacturer.

(천)', 'ㅡ(지)' 및 'ㅣ(인)'과 같은 모음이 배치된 예로써, '

(천)', 'ㅡ(지)' 및 'ㅣ(인)'을 통해 원하는 모음을 조합할 수 있다.In the case of FIG. 1, the consonants from 'ㄱ' to 'ㅎ' and '

(Thousands), ㅡ (지), and ㅣ (in),

(Thousand), 'ㅡ (지)' and 'ㅣ (인)' can combine the desired vowels.

'이 배치된 숫자키 2를 1회 눌러 'ㅏ'를 입력하고, 'ㄴ', 'ㄹ'이 배치된 숫자키 5를 1회 눌러 'ㄴ'을 입력하는 순서를 통해 '한'을 입력하게 된다. 또한, 'ㄱ', 'ㅋ'이 배치된 숫자키 4를 1회 눌러 'ㄱ'을 입력하며, 'ㅡ'이 배치된 숫자키 3을 1회, '

'이 배치된 숫자키 2를 1회 눌러 'ㅜ'를 입력하고, 'ㄱ', 'ㅋ'이 배치된 숫자키 4를 1회 눌러 'ㄱ'을 입력하는 순서를 통해 '국'을 입력하게 된다.For example, in order to input 'Korea', first press the number key '8' with 'ㅅ' and 'ㅎ' two times in a row to enter 'ㅎ', and enter the number '1' with 'ㅣ' 1 Times,

Press '1' once with '2' to input 'ㅏ', and press '1' once with 'n' and 'ㄹ' to enter 'n'. do. In addition, by pressing the number key 4 is placed once 'ㄱ', 'ㅋ' is entered 'ㄱ', and the number key 3 '''is placed once,'

Press '1' once with '2' to input 'TT', and press '1' once with 'ㄱ', 'ㅋ' and press '1' to input 'station'. do.

However, in the portable communication device according to the related art, since the consonants and vowels are arranged on the numeric keys 0 to 9 of the Korean consonants and vowels, the user inputs the Korean syllables using the ten numeric keys. Therefore, even in the case of an electronic device that does not require a numeric key, 10 keys are required to input Korean syllables, which causes a limitation in miniaturization of the electronic device.

In addition, since the user must use all ten keys to input Korean syllables, the time required for inputting Korean syllables increases.

An object of the present invention is to provide a Hangul input device and method that can reduce the number of keys for inputting consonants and vowels of Hangul.

The object of the present invention is not limited to the above-mentioned object, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

Hereinafter, the Hangul input method according to an embodiment of the present invention will be described in detail.

4 is a diagram illustrating a Hangul input method according to an embodiment of the present invention.

As shown, first, the user inputs the consonants of the Hangul syllables by using the above-described input method (S110). At this time, the input of the initial can be input through the above-described first key 111 to the fourth key 114, the user is the first key 111 to the fourth key ( 114).

When the user inputs the consonants using the first keys 111 to the fourth keys 114, the controller 130 determines whether the consonant input is completed (S120). Specifically, the first consonants may be made of a terminal sound like 'a', or may be made of a consonant sound like 'ㄲ'. Accordingly, the controller 130 may determine the terminal sound when the vowel is input after the consonant input and the same consonant is input again after the consonant input, referring to Tables 1 and 2 above.

After the initial input, the user inputs the neutral corresponding to the vowel through the first key 111 to the fourth key 114 (S130). The user may input a desired collection with reference to Table 2 above.

When the user completes the neutral input (S140), the controller 130 determines whether the syllable input is completed (S150). In other words, the Hangul syllable may be composed of initial and neutral or initial, neutral and final. Therefore, when the user inputs syllables composed of initial and neutral, the user completes the input after the neutral input is completed.

On the other hand, when the syllable input is not completed, that is, when the syllable includes the final word, the user inputs the consonant corresponding to the final word through the first keys 111 to the fourth key 114 when the neutral input is completed. (S160). The user inputs the finality with reference to Table 1, as described above, and the controller 130 determines whether the finality is a terminal sound or a double-tone sound.

For example, the final word of the Hangul syllable may include a terminal sound such as 'ㄱ' or a bokja sound such as 'ㄲ' and 'ㄼ'. Accordingly, the controller 130 may determine whether the finality consists of one consonant or a plurality of consonants to complete the Hangul syllable together with the above-mentioned consonants and neutrals.

When the user completes the final input (S170), the controller 130 determines that the syllable input is completed, and completes the syllable through the initial, neutral, and final inputs input in steps S110, S130, and S160.

On the other hand, in the embodiment of the present invention has been described a case where the Hangul syllables are composed of the initial and neutral or the first, neutral and final, for example, but is not limited to this may also be applied to the case where the Hangul syllables are composed only of the first. .

As described above, the Hangul input method according to the embodiment of the present invention inputs all the consonants and vowels of Tables 1 and 2 described above through four keys, such as the first key 111 to the fourth key 114. Can be. Therefore, in the case of an electronic device that does not require a numeric key, it is possible to miniaturize the electronic device by forming only the first key 111 to the fourth key 114, which makes it possible to miniaturize a portable electronic device such as a portable communication device and a PDA. It becomes possible to realize anger.

As described above, the Hangul input device and method according to the present invention have been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and by those skilled in the art within the technical scope of the present invention. Of course, various modifications may be made.

According to the Hangul input device and method of the present invention as described above, since the consonants and vowels of the Hangul can be represented with only four keys, the electronic device using the Hangul input can be miniaturized.
