Description

Method for inputting letters korean character in radio communication terminal}

The present invention relates to a method of inputting Hangul using a numeric button of a keypad in a Personal Communications Service (PCS) terminal or a mobile phone terminal. The present invention relates to a Hangul consonant / vowel input method of a mobile communication terminal which inputs a Hangul syllable by a combination.

In general, a mobile communication system transmits a call message including a unique number of a mobile communication terminal through a call control channel of a base station, and provides a communication path wirelessly when a response is received from the corresponding terminal, thereby providing convenience of a telephone call at a long distance. And the pursuit of mobility.

In particular, such a mobile communication system has been able to provide data communication by adopting a digital communication method in recent years, and thus can provide various services such as a short message service through data communication.

Along with this, various methods for inputting English, Korean, and special characters as well as numbers using a keypad in a mobile communication terminal have been proposed. In order to realize this, a predetermined character in addition to the numbers is input to the keypad as illustrated in FIG. 1 or 2. The characters are entered in parallel.

A Hangul input method using the keypad shown in FIG. 1 will be described as an embodiment of the prior art.

In the keypad, two or three Hangul consonants or vowels corresponding to the corresponding buttons are written on the number pad, that is, "a, ㅏ, ㅑ" for 1, "b, ㅓ, ㅕ" for 2 , 3 for "ㄷ, ㄹ, ㅁ", 4 for "ㅂ, ㅗ, ㅛ", 5 for "ㅅ, TT, ㅠ", 5 for "ㅇ, ㅡ", 7 for "ㅈ, ㅁ, ㅣ", 8 "ㅋ, ㅌ" in the "9," ッ, ㅎ "is written.

In such a state, when a telephone number is input for a call, the number is inputted by dialing a button in which the corresponding number is specified in the same way as the number input button of other devices.

In case of inputting Hangul, the consonants or vowels written on the button are sequentially selected according to how many times the same number button is operated after switching from the call mode to the Hangul input mode by operating a separate function button. Lose.

For example, pressing the number button [3] once will display the first character “ㄷ” on the LCD, pressing [3] twice in succession will show “ㄹ”, and pressing three times in succession will display “ㅁ”. Is displayed.

That is, if you keep pressing [3], you will see "ㄷ", "ㄹ", "ㅁ", "ㄷ", "ㄹ"…. Appears sequentially on the LCD, and when the desired consonant or vowel appears, pressing the navigation key ([*] / [#], etc.) or when a certain time elapses, the currently selected consonant or vowel is input to the mobile terminal, and the next syllable The cursor of the liquid crystal display is moved to receive the input.

A Hangul input method using the keypad shown in FIG. 2 will be described as another embodiment of the related art.

Hangul consonants / vowels are arranged on the keypad according to the Adjacent Touch-Tone Assembly Code for Hangul (ATTACH), and the conventional Korean input method using the ATTACH includes 12 with 12 different signal values. Hangul is input by the adjacent button relationship of the dog buttons.

For example, to enter "a", press [1] first, then [2] next, then [2], then press [1] next to it, and "b" is entered.

In the case of "c", it is input diagonally by pressing [1] first and then [5] next. In other words, each Korean consonant / vowel represented by this method is set to two adjacent button values.

In the above-described conventional Korean input method, it can be seen that all consonants and vowels of the Korean alphabet should be marked between the numeric buttons or the buttons and the buttons.

Therefore, the appearance is not beautiful as a large number of characters are densely printed, and in particular, there is a problem in that it is difficult to print characters in a size large enough to be easily recognized by a person with ordinary eyesight.

Moreover, it is obvious that as the mobile communication technology develops day by day, terminals become smaller and smaller, and as the size of the terminals decreases, the size of the buttons and the distance between the buttons and the buttons are reduced, which is larger for specifying all consonants and vowels in Korean. Difficulties will follow.

Therefore, a method of inputting Korean consonants / vowels of a mobile communication terminal that can reduce the number of characters displayed on the keypad as much as possible while creating effects equivalent to those of the conventional one in terms of Korean input speed or the like is preferable.

Therefore, the present invention excludes the problem of having to write a large number of characters on the keypad in the above-described prior art, and divides the consonants and vowels of the Korean alphabet into geometrically smaller basic consonants / vowels than the number of consonants / vowels. After separating, only this basic letter is written on the number pad of the keypad, and when the basic letter is input sequentially, the syllable is completed by the combination, so that the Hangul is input.

First: to facilitate the printing of characters on the keypad, second: to improve the character recognition of people with low vision, third: to improve the beauty of the appearance of the terminal, and fourth: to improve the scalability of the text input. Its purpose is to.

3 is an external view of a keypad for performing a Korean consonant / vowel input method of a mobile communication terminal according to the present invention;

4 is a flowchart illustrating a Hangul recognition process of a mobile communication terminal associated with the Hangul consonant / vowel input method according to the present invention.

Korean consonant / vowel input method of the mobile communication terminal according to the present invention for achieving the above object, in the mobile terminal using the numeric keypad of the keypad to input:

The Korean consonants / vowels are geometrically divided into fewer basic shapes than the total consonants / vowels,

Corresponding to the basic shape and the number button,

Combining the number buttons according to the geometric shape of the consonant / vowels, characterized in that to input the basic shape sequentially.

Preferably, the basic shape and the number button, characterized in that corresponding to 1: 1.

Preferably, the end of the syllable by the sequential combination of the basic shape is divided into specific buttons.

Optionally, the basic consonant of the consonant is composed of a general consonant and a consonant special symbol including “a, b, ㅂ, ㅅ, ㅇ”, and the general consonant is combined with the special consonant symbol for another consonant. Characterized in that the input.

Optionally, the basic vowel shape of the vowel is composed of a general vowel and a special symbol for vowel, including “-a, ㅣ”, and the general vowel is combined with the special vowel for vowel and input into another vowel. .

In this way, even if the number of characters less than the number of consonants and vowels of Hangul can be written on the keypad, Korean characters can be input at a high speed. Identification ability is improved, and the appearance of the terminal is improved.

There may be a plurality of embodiments of the present invention. Hereinafter, the most preferred embodiment will be described in detail with reference to the accompanying drawings.

This preferred embodiment allows for a better understanding of the objects, features and advantages of the present invention.

In addition, the technology of the present invention can be applied to various products capable of inputting characters by operating keypads such as general telephones, calculators or automatic teller machines as well as PCS phones and mobile phones.

Therefore, FIG. 3 used in the description is not limited to a specific mobile communication terminal, and is a drawing of various text input devices capable of inputting characters using a keypad provided with numeric buttons. Consider an example applied to a PCS phone to help.

In the present invention, 14 Korean consonants and 10 vowels are geometrically divided into 6 basic consonants and 3 basic vowels, and a total of 9 basic consonants less than the total number of consonants / vowels are shown in FIG. 3. 1-1 corresponds to the number buttons 1 to 9 to specify.

The basic consonant of consonants consists of five general consonants (a, b, ㅂ, ㅅ, ㅇ) and one special consonant symbol (-). The basic vowels of the vowel are two general vowels (ㅣ, ㅡ) and 1 It consists of two special symbols (·) for vowels.

General consonants (ㄱ, ㄴ, ㅂ, ㅅ, ㅇ) and ordinary vowels (ㅣ, ㅡ) are entered as the corresponding consonants or vowels when they are entered alone. When entered sequentially with the symbol (-), it is combined with other consonants. When the normal vowel (ㅣ, ㅡ) is entered with the special symbol (·) for vowels sequentially, it is combined with other vowels. Ends of syllables by sequential combinations of basic shapes are separated by specific buttons (□).

Accordingly, in the present invention, the basic consonant / vowel combination principle of the Hangul is as follows.

1. Among the general consonants, "ㄱ" is input as "ㅁ" in combination with "ㄴ", is input as "ㅋ" in combination with the special consonant symbol (-) for consonants, and the special symbols (-) and "ㄴ" for consonant consonants. In combination with ".

2. Among the general consonants, "b" is input as "ㄷ, ㅌ" in combination with a special symbol (-) for the consonant.

3. Among the general consonants, "ㅂ" is input as "" "in combination with a special symbol (-) for consonants.

4. Among the common consonants, "ㅅ" is entered as "ㅈ, ㅋ" in combination with the special consonant symbol (-).

5. Among general consonants, "ㅇ" is input as "ㅎ" in combination with the special symbol (-) for consonants.

6. Among the general vowels, "ㅡ" is input as "ㅗ, ㅛ, ㅜ, ㅠ" in combination with the special symbol (·) for vowels.

7. Among general vowels, "ㅣ" is input as "ㅏ, ㅑ, ㅓ, ㅕ" in combination with a special symbol (·) for vowels.

Based on the consonant / vowel combination principle described above, the operation sequence of the numeric buttons for inputting each consonant and a vowel is summarized as follows.

I. Consonant input

The Hangul consonants / vowels are input by the method as described above, and a control device such as a microprocessor that controls the overall functions of the mobile communication terminal recognizes the Hangul input sequentially through the processing shown in FIG. 4.

As an example for clarity of explanation, a process of inputting a short sentence “bright moon” and a process of recognizing it by the microprocessor will be described with reference to FIGS. 3 and 4.

First, when the user operates the corresponding function button on the keypad, the PCS general mode or the Hangul input mode is selected. In this case, when the Hangul input mode is selected to input the short text, the terminal waits for the Hangul type to be input. ST4).

Thereafter, when the user sequentially presses the number buttons “4, 7, 8, 1, 2, 3, 1”, basic shapes of “ㅂ, ㅣ, ·, ㄱ, ―, ㄴ, ㄱ” are sequentially input, and the terminal Whenever the basic shape is input, it determines whether it is possible to combine with the previously inputted shape sequentially.If the combination is possible, it recognizes by combining the currently inputted shape with the previously inputted shape. Recognizes the separated and previously entered shapes.

Therefore, "4" is entered as "ㅂ", "7, 8" is combined and entered as ",", "1, 2, 3" is combined and entered as "ㄹ", and "1" is " A "is inputted (ST5 to ST8).

When the user presses the number button "0", the terminal recognizes that one syllable has ended and recognizes the shapes of the input so far as one syllable "bright" and stores it in volatile memory and waits for the next syllable to be input. (ST9 to ST10).

Here, the end of the syllables by the sequential combination of basic shapes is distinguished by a specific button to distinguish between the last syllable and the first syllable.

Next, when the user sequentially presses the numeric buttons "6, 9, 3, 0", the terminal recognizes "silver" by the recognition process as described above and stores it in the volatile memory and waits for the next syllable to be input again. .

In addition, when the user presses the number button "0" again and again after successively pressing the number button "0" to distinguish the end of the syllable as described above, a space is input after the syllable "silver".

Then, when the user sequentially presses the number buttons "2, 3, 7, 8, 1, 2, 3", the terminal recognizes "moon" by the recognition process as described above and stores it in the volatile memory.

After the short text is completed through this process, when the user presses a specific selection button, the entire short text “bright moon” is stored in the nonvolatile memory and inputted to the terminal.

While specific embodiments of the present invention have been described and illustrated above, it will be apparent that various modifications may be made by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

Comparing the present invention and the prior art as described above, unlike the prior art in which both the Korean consonants / vowels are written together on the keypad or both the buttons and the buttons are written together, the present invention is less than the total number of consonants / vowels. It can be seen that Korean characters can be input at an input speed equal to or greater than the number of basic shapes written on the number buttons.

As a result, the present invention, the number of characters to be printed on the keypad is reduced, the printing operation is easy, as well as the beautiful appearance of the terminal is improved, and the characters can be printed larger, character recognition ability of people with low vision This is improved.

In addition, various characters may be added to the free space of the numeric button, thereby improving the scalability of character input.
