If one of the four vowel / special character keys is selected at the same time, one of the vowels and double vowels other than the basic vowel group is generated. Create and display on the screen. If any one of the special characters assigned to the eight consonants / special character keys and four vowels / special character keys is selected, create the special characters assigned to the key and display the screen. Show on Characterized in that.

Hereinafter, a Hangul input method of a mobile communication terminal and a mobile communication terminal of the present invention will be described in detail with reference to the accompanying drawings.

Hangul is based on the unification of Korean spelling, a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ,, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ Twenty-one of the four foramen, ,, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅔ, ㅖ, ㅚ, ㅟ, ㅢ, ㅘ, ㅝ, ㅙ, ㅞ Neutral, a, b, c, d, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k It consists of 28 species,, ㅀ, ㅯ, ㅄ. Therefore, the number of letters that can be theoretically formed by combining initial, neutral, and final is 11,172 (19 × 21 × 28) characters. However, the actual number of characters commonly used is about 2,500 characters, and in the case of commonly used completed codes or combined codes, 1800 to 1900 characters can be expressed in Korean.

In the present invention, consonants, vowels, and special characters are respectively assigned to 12 keys (1, 2, 3, 4, 5, 6, 7, 8, 9, 0, *, #) of 3 rows and 4 columns provided in the mobile communication terminal. Assigns, selects consonants, vowels, and special characters assigned to each key, and shows how to combine the characters; general functions such as up, down, left, and right movement for quick character input, and cancellation to erase the entered character. Special characters follow the basic settings commonly applied to mobile communication terminals.

1 is a block diagram schematically showing the configuration of a Hangul input device of a mobile communication terminal to which the Hangul input method according to the present invention is applied.

As shown, a key input unit 12 for outputting consonant, vowel, and special character selection signals assigned to each of the 12 keys selected by the user to the control unit 14, and controls driving of the mobile communication terminal, The controller 14 controls to generate a font of a character corresponding to a consonant, vowel, and special character selection signal inputted from the input unit 12, and to display it on the screen, and fonts for Korean consonants, vowels, and special characters are embedded.

FIG. 2 is a diagram illustrating a keypad structure applied to a Korean input method of a mobile communication terminal according to the present invention. When a consonant, a vowel, and a special character are assigned to a keypad of a mobile communication terminal, a coding method is input (consonant two) Inputting dogs at the same time or inputting two vowels simultaneously) is designed so that there are no overlapping consonants.In case of vowels, Korean is easily input by using the method used by Koreans when learning Korean and English phonetic notation. The principle is to design the method so that it can be learned.

As shown, the three-row, four-column keypad of the mobile terminal according to the present invention includes eight consonant / special character keys 22 to which basic consonant groups and / or special characters are assigned, and basic vowel groups and / or special characters. It consists of four vowel / special character keys 24 assigned to. For example, consonants / special character keys are assigned to 1, 2, 3, 4, 5, 6, 7, and 9, and vowel / special character keys are assigned to 8, 0, *, and #.

At this time, the basic consonant group is composed of a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ and ㅎ, and the basic vowel group is composed of ㅏ, ㅓ, ㅗ, TT, ㅡ and ㅣ.

Eight consonants / special character keys 22 are assigned up to two consonants and / or special characters such as consonants and consonants, consonants and special characters, and four vowels / special character keys 24 are assigned to vowels, vowels, vowels Up to two vowels and / or special characters, such as special characters, may be assigned. Then, when the user enters consonants, vowels, and special characters assigned to each key, pressing the key once displays the first assigned letter on the screen, and pressing the same key twice in succession, the second assigned letter. Is displayed on the screen.

The special characters assigned to some of the eight consonants / special character keys 22 and the four vowel / special character keys 24 are set to special characters that are commonly used in the mobile terminal manufacturing stage. Of course, it can be used to change arbitrarily at your convenience. That is, when the user selects to change the special character, the control unit 14 of the mobile communication terminal displays all the registerable special characters on the display unit 18, and the user who confirms the new special characters and the key to which the special characters are assigned are displayed. When selected, changes the special character assigned to the key to a new special character selected by the user.

When two consonant / special character keys of the eight consonant / special character keys 22 are selected by the user at the same time, the mobile communication terminal is the sound of ㅋ, ㅌ, ㅌ, ㅍ, or ㄲ, ㄸ, ㅆ, ㅉ, ㅃ. 경, or 합, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅯ, 생성 and create a combination statement on the screen.

That is, a consonant function is assigned to a key to which a consonant is assigned to the consonant / special character key 22, and the user is assigned to the key to which the consonant function is assigned and a, c, r, ㅂ corresponding to the flat sound of each consonant. When the basic consonant group of is selected simultaneously with the assigned key, the mobile communication terminal displays the sound of k, k, k, k on the display unit 18. In addition, a consonant function is assigned to a key to which consonants are assigned to the consonant / special character key 22, and the user is assigned to the consonant function and the a, c, ㅅ, r If the basic consonant group of, ㅂ is selected at the same time, the mobile communication terminal displays the beep on the display unit 18 of k, k, k, k, k. In addition, when the user selects two keys of the consonant / special character key 22 at the same time, the mobile communication terminal checks whether the two consonants simultaneously selected by the user are a key combination that can generate a combined disease statement, and then generates a combined disease statement. If this possible key combination is displayed on the display unit 18, a combination statement of ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅯ, ㅄ will be displayed at the same time.

If two vowel / special character keys of the four vowel / special character keys 24 are selected by the user at the same time, the mobile communication terminal has a half vowel of ㅑ, ㅕ, ㅛ, ㅠ, or ㅐ, ㅒ, ㅔ, ㅖ, ㅚ. Create a double vowel of, ㅟ, ㅢ, ㅝ, ㅝ, ㅙ, ㅞ and display it on the screen.

That is, when the vowel / key, 24, ㅗ, ㅜ, and the vowels assigned to the basic vowel group corresponding to 'y' of the English phonetic notation among the vowel / special character keys 24 are selected at the same time, The communication terminal generates a half vowel of ㅑ, ㅕ, ㅛ, ㅠ and displays it on the display unit 18. In addition, if two keys of the vowel / special character key 24 are selected at the same time, the mobile communication terminal checks whether two vowels simultaneously selected by the user are a key combination capable of generating a double vowel, and then a double vowel can be generated. In the key combination, a double vowel of V, V, V, V, V, V, V, V, V, V and V is generated and displayed on the display unit 18 at the same time.

After one consonant / special character key of the eight consonant / special character keys 22 is selected by the user and the finality is input, the first character of the next character is not input for a preset time (for example, 2 seconds). Otherwise, the mobile communication terminal recognizes the character input as the last character as the first character of the next character.

When the user inputs any one of the eight consonant / special character keys 22 and the four vowel / special character keys 24 by a user for a preset time (for example, two seconds), the mobile communication terminal Generates a number assigned to the key and displays it on the screen.

Are assigned, consonants 'ㅂ' and special characters ':' are assigned to keys 4, consonants 'ㅅ' and 'ㅁ' are assigned to keys 5, 6 Key is assigned consonant 'ㅈ' and special character ';', key 7 is assigned consonant 'ㅇ' and sound function, key 8 is assigned vowel 'ㅏ' and 'ㅓ', and key 9 is assigned. Keys are assigned consonants 'ㅎ' and the sound function, * keys are assigned vowels 'ㅗ' and 'TT', keys 0 are assigned vowels 'ㅡ' and the special character '@', and # keys are vowels. 'ㅣ' and the special character '?' Are assigned.

An example of the Hangul input method according to the present invention will be described using the keypad of FIG. 3 as an example.

Mobile device users say, 'Cheol and Young-Hee are friends.' In the Korean input method according to the present invention, enter the following order (where + indicates simultaneous input).

Iron: (9 + 6) / 8/8/2/2 (5 strokes)

-Number: 5 / * / * (3 strokes)

-With: 7 / (8 + *) (2 strokes)

Space: Arrow keys (1 stroke)

Young: 7 / (# + 8) / (# + 8) / 7 (4 strokes)

-Hee: 9 / (# + 0) (2 strokes)

-Is: 2/0/2 (3 strokes)

Space: Arrow keys (1 stroke)

-Chin: (9 + 6) / # / 2 (3 strokes)

-Sphere: 1 / * / * (3 strokes)

Mouth: 7 / # / 4 (3 strokes)

-Knee: 2 / # (2 strokes)

-Everything: 3/8 (2 strokes)

-. (Special characters): 3/3 (2 strokes)

Taking the above sentence as an example, a total of 36 key inputs are performed by the Korean input method according to the present invention. However, when inputting Hangul according to Cheonjiin's most widely used method, 43 keystrokes are required except for the special character '.'.

That is, the Hangul input method of the mobile communication terminal according to the present invention can generate one character by pressing two keys simultaneously assigned with consonants, vowels, and special characters, and directly input the special characters. We can see that a much smaller number of keystrokes are required.

Next, the process of the Hangul input method of the mobile communication terminal according to the present invention will be described in detail with reference to FIG.

Figure 4 is a flow chart illustrating in detail the process of the Hangul input method of the mobile communication terminal according to the present invention.

After displaying the syllables of the syllable and the neutral on the screen, the mobile terminal determines whether the user selects the consonant / special character key 22 to input the final syllable (S110), and the consonant / special character key (22). ) Selects one consonant / special character key (22) for basic consonant input, or ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅯ, ㅄ It is determined whether two consonant / special character keys 22 for input are simultaneously selected (S120).

As a result of the determination, when the user selects two consonant / special character keys 22 for inputting the combined medical note at the same time, the mobile communication terminal displays the corresponding selected combined medical note on the screen with the finality of the syllable (that is, the above-described step S100). (S130) to complete the syllable by combining the consonant / neutral of the syllable displayed in the syllable (S130), and when the user selects one consonant / special character key (22), a, b, c, d, d, r, k , ㅅ, ㅇ, ㅈ and ㅎ by displaying the final consonants of the syllable on the screen to complete the syllable (S140).

After one syllable is completed, the mobile communication terminal determines whether the user ends the input of Hangul and special characters, and when the input of the Hangul and special characters ends, stops the text input mode and ends the input of the Hangul and special characters. If not, it is repeated after step S10 described above (S150).

On the other hand, the user does not select the consonant / special character key 22 in step S30, or the user does not select the vowel / special character key 24 after the syllable of the syllable is displayed in step S70, or the syllable in step S110. If the user does not select the consonant / special character key 22 after the initial / neutrality is displayed, the mobile terminal displays the character displayed in its current state as it is, regardless of whether the syllable is completed. Display of Korean characters or special characters.

In addition, after the user selects a specific consonant / special character key 22 and inputs the finality of the syllable, if the user does not input the initiality of the next character for a predetermined time, the mobile terminal automatically generates the finality as the initiality of the next character. Recognize and display on the screen.

In addition, when the user continuously presses the consonant / special character key 22 or the vowel / special character key 24 for a predetermined time, the mobile communication terminal displays the number assigned to the corresponding key on the screen.

In addition, if a user who wants to input English characters other than Korean / special characters selects the mode change, the mobile communication terminal changes the Korean / special character input mode to English input mode, and then displays the corresponding English characters according to the user's key operation. Mark on.

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.
