Korean Patent Registration Publication No. 0159191

The present invention relates to a method of generating a character using a key and processing a phoneme using the generated character. More particularly, the present invention relates to a method of inputting a consonant using the same consonant key, which is a problem of Korean characters. The present invention relates to a Hangul input method that eliminates the inconvenience of having to wait or press a direction key disposed at a considerable distance from the Hangul input keypad.

Devices that display and enter text, such as computers, cell phones, and personal digital assistants (PDAs), have a plurality of keys corresponding to the phonemes of each letter, and each of the keys has a particular type of code. And combinations thereof display characters on the display of the character input apparatus or store them in the memory of the character input apparatus. Therefore, such a computer or similar input / display devices must be provided with a keyboard having a plurality of keys arranged for inputting the characters. As a conventional character input device, at least 26 or more keys must be provided to smoothly input Korean or English characters in a desired form, and codes corresponding to the keys must be provided.

However, the conventional character input device as described above has a very large volume and is difficult to carry, and it is difficult to be applied to a compact system due to a problem of installing a plurality of keys for inputting characters. For example, they could not be used in systems with less keys, such as cell phones, calculators, and organizers.

Another conventional character input method is a method of inputting / displaying a character using a push button switch installed in a telephone. Such a method is disclosed in a character input code (hereinafter referred to as a dissertation) using an electronic telephone, published on page 271 of the 4th Korean & Korean Information Processing Society Proceedings. The Multiple Depression method, Single Depression method, Shift Key method, Code Table method, Adjacent button combination method, etc. disclosed in the paper display at least one or more characters on the digit button of the keypad of the telephone for dialing. It generates a character code that is input in advance according to the number of inputs or the '*', '0', and '#' keys.

In addition to the above method, strokes such as the writing stroke order are assigned to the minimized numeric keys, such as Patent Application No. 93-12632, filed July 6, 1993, and the stroke keys in the writing stroke order and the writing direction. There has been developed a method and apparatus for generating code for character input by manipulating.

However, the character input method in the telephone using the multiple depression method as described above is complicated because the number of consonants assigned to one key is too large. In addition, the adjacent button combination method has a problem that it is difficult to master the input method. In addition, the character input method pre- filed by the applicant of the present application has a problem in that it is somewhat inconvenient to use when the input number of keys is large when a consonant is input. In particular, when it is necessary to search for the character input by patent application No. 93-12632, the number of times of input increases and there is a disadvantage in that the delimiter key must be pressed.

According to Korean Patent Registration Publication No. 0149191, which is another conventional Korean input method for solving the above problems, it is possible to assign a phoneme of a Korean consonant to a plurality of keys and input a desired character as a minimum stroke key. It provides a character input device and method for inputting a vowel of a letter, and assigns a plurality of consonants of Korean characters to a key of a minimized number, assigns strokes according to two handwritten strokes, and inputs Korean characters by inputting the keys. An apparatus and method for generating code are provided.

Korean Patent Registration Publication No. 0159191 discloses an apparatus and method for generating a character input code. According to the above patent publication, there is disclosed an apparatus for generating codes of consonants and vowels for Korean input, having only a plurality of stroke keys in the horizontal and vertical directions and a plurality of numeric keys assigned with a plurality of at least two consonants.

A terminal based on the Hangul input method as described above and currently distributed in the market is a Hangul keyboard as shown in FIG. 1. However, according to the method disclosed in the above patent publication, when the consonant is input using the same consonant key, it is inconvenient to wait for a certain time or press a direction key disposed at a considerable distance from the Hangul input keypad. For example, to enter "by mail" you must generate a phone number of "ㅁ. ㅣ ㅇ ㅣ ㄹ ㄹ ㅗ" and press "002110155 (Standby or arrow keys) 5523". If 5,5 (without pressing the standby or direction key) is pressed 5,5, the previous consonant key 'ㄹ' is recognized as 'b' and becomes 'Meino'.

In addition, in "we (blank) ethnic (blank) revival", we need to use the arrow keys to enter a space, which means that the user has to press a direction key placed at a considerable distance from the keypad for inputting the text. There is a problem.

The technical problem to be solved by the present invention is to solve the above problems, the direction key is waiting for a certain time when input the consonant using the same consonant key, which is a problem of the so-called cheonji Hangul or arranged a considerable distance from the Hangul input keypad It is to provide a Hangul input method that eliminates the inconvenience of pressing.

Another object of the present invention is to provide a Hangul input method that eliminates the inconvenience of pressing a direction key disposed at a considerable distance from the Hangul input keypad in order to input a space.

In the Hangul input method according to the present invention for achieving the technical problem as described above in the Hangul input method for a mobile terminal using a keypad,

(h) identifying whether the second phoneme is a vowel if the first phoneme is identified as an incomplete "-"; And

(i) if the second phoneme is a vowel, replacing the incomplete "-" which is the first phoneme with a space;

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

2 is a flowchart illustrating main steps of a Hangul input method for a mobile terminal according to an exemplary embodiment of the present invention. Referring to FIG. 2, the Hangul input method for a mobile terminal according to an embodiment of the present invention is based on a conventional automata, but to solve the above-described problem, when a consonant comes in, the phoneme immediately before the consonant is pre-provisioned. The key is to identify and correct stroke keys or vowels that are incomplete.

)인지를 식별한다(단계 S104). 본 명세서에서는 초성 직전의 음소를 제1 음소라 칭한다. 만일, 단계(S104)에서 이전 음소, 즉, 제1 음소가 불완전한 아래아(

)인 것으로 식별되면 그 이전 음소가 종성인지를 식별(단계 S106)한다. 본 명세서에서는 상기한 그 이전 음소를 제2 음소라 칭한다. 제2 음소가 종성이 아닌 경우에는 앞의 음소와 결합하여 새로운 모음을 형성하기 때문에 잘 못 변환되는 것을 방지하기 위함이다. 단계(S106)에서 제2 음소가 종성인 것으로 식별되면 상기 제2 음소가 초성과 동일한지를 식별한다(단계 S108). 단계(S108)에서 제2 음소가 초성과 동일하다고 식별되면 불완전한 아래아(

)를 무시하여 제거(단계 S110)하고 초성을 유용한 자음으로 처리한다. 반면에, 단계(S108)에서 제2 음소가 초성과 동일하지 않은 것으로 식별되면 불완전한 아래아(

)를 공백(" ")으로 대체한다(단계 S112).First, it is discriminated whether or not the phoneme that has entered the automata is initial (step S102). If the phoneme that enters the automata is identified as an initial, the previous phone, that is, the phone immediately before the initial, is incomplete.

(Step S104). In the present specification, the phoneme immediately before the initial generation is referred to as a first phoneme. If, in step S104, the previous phone, that is, the first phone is incomplete,

Is identified), it is identified whether the previous phoneme is final (step S106). In the present specification, the previous phoneme described above is referred to as a second phoneme. When the second phoneme is not the final phoneme, the second phoneme is combined with the previous phoneme to form a new vowel, so as to prevent the wrong conversion. If it is identified in step S106 that the second phoneme is the last one, it is identified whether the second phoneme is the same as the initial number (step S108). In step S108, if it is identified that the second phoneme is the same as the first consonant, it is incomplete.

) Is ignored and removed (step S110), and the initial consonants are processed into useful consonants. On the other hand, if it is identified in step S108 that the second phoneme is not the same as the initial,

) Is replaced by a space ("") (step S112).

)를 제거하고, 제2 음소가 모음인 경우에는 제1 음소로써 "ㅡ"가 입력된 경우에만 제1 음소인 불완전한 "ㅡ"를 공백으로 대체한다. 즉, 단계(S104)에서 이전 음소, 즉, 제1 음소가 불완전한 "ㅡ"인지를 식별하고, 제1 음소가 불완전한 "ㅡ"인 것으로 식별되면, 그 이전 음소, 즉, 제2 음소가 모음인지를 식별(단계 S114)하여, 제2 음소가 모음이면 고의로 잘 못 입력된 제1 음소인 불완전한 "ㅡ"를 공백으로 대체한다.Meanwhile, as described above, the second phoneme may be a vowel, not a consonant. In this case, a conversion error may occur because the second phoneme is not vertical and may combine with the previous phoneme to form a new vowel. In order to prevent this, incomplete undertone (first phoneme intentionally input only when the second phoneme is final)

), And when the second phoneme is a vowel, the incomplete "-" which is the first phoneme is replaced with a space only when "-" is input as the first phoneme. That is, in step S104, if the previous phone, i.e., the first phone is identified as incomplete "-", and if the first phone is identified as incomplete "-", then the previous phone, i.e., the second phone is a vowel. (Step S114), if the second phoneme is a vowel, it replaces the incomplete "-" which is the first phoneme, which is intentionally incorrectly input, with a blank.

Therefore, according to the present invention, '-' is intentionally input to separate from the previous vowel. In other words, conventionally, 'ㅎ ㅣ

In general, people entering letters not only recognize the consonants, the neutrals, and the final consonants, but also clearly recognize the consonants and vowels. "Inputting spaces with the intention of inputting a space with sufficient intention is that if you are a little familiar with it, you can enter Korean characters very quickly and conveniently compared to pressing a direction key placed in a relatively distant position.

As described above, according to the present invention, when the consonant is input using the same consonant key, which is a problem of the so-called Korean alphabet, the inconvenience of waiting for a certain time or pressing a direction key arranged at a considerable distance from the Hangul input keypad is eliminated.
