The present invention relates to a character input device and method of a communication terminal, and more particularly, to a character input device and method of a communication terminal for easily inputting Hangul using the Hangul creation principle, Cheonjiin, Bagua principle.

Along with technology expansion of wired communication services, technological advances in personal wireless communication services such as Personal Communication Service (PCS) based on code division multiple access (CDMA) technology and the rapid increase in the number of subscribers Various additional services have been developed and are currently being actively serviced.

Among these additional services, a short message service for inputting and transmitting text through an input button configured in the terminal and a chat service of a wireless communication terminal capable of accessing the Internet occupy the largest portion.

In addition, recent communication terminals are configured with an electronic notebook function for storing daily, weekly or monthly schedule information and contact information as well as a voice call function and a message function.

As described above, as the communication terminal is used for various purposes such as Internet chat, text message transmission, electronic notebook, etc., it has become an important problem to input texts more simply and quickly. In particular, it is not easy to input Hangul by combining consonants and vowels using input buttons configured in an increasingly smaller communication terminal. Various methods for inputting Hangul more conveniently and quickly have been proposed.

FIG. 1 is a view illustrating a character input of a communication terminal according to the prior art. When a function for inputting Korean is selected according to the menu button 102 of the communication terminal 100, the liquid crystal display 104 is selected. A plurality of consonants are displayed and the desired consonants are selected using the direction keys 106 and 108. Subsequently, a plurality of vowels are displayed on the liquid crystal display 104 of the communication terminal 100, and the desired vowels are selected using the direction keys 106 and 108 in the same manner as the consonant selection.

On the other hand, Figure 2 is a view showing another embodiment of the character input of the communication terminal according to the prior art.

As shown in FIG. 2, the numeric keys 210 of 1 to 3 of the communication terminal 200 are assigned '-', 'ㅣ', '·' for displaying a vowel, and the numeric keys 4 to 0. Two consonants are allocated to the 220.

Here, a vowel is input by combining '-', 'ㅣ', '·' assigned to the numeric keys 210 of 1 to 3. For example, press 'ㅣ' and press '·' once to enter 'ㅏ', and press 'ㅣ' and press '·' twice to enter 'ㅑ'.

In addition, two consonants assigned to the number key 220 of the 4 to 0 to select the desired consonant by successive presses, pressing the 4 number key once 'b', pressing the 4 number key twice in a row 'ㅋ 'Is entered.

In the above-described conventional technology, when an English or special character is to be input in addition to Korean, special character input is performed by selecting an English or special character input function according to a menu button.

Therefore, in the prior art, since consonants and vowels are displayed on the liquid crystal display in the inputting of Hangul, a desired character is selected or consonants or vowels assigned to the button are simply assigned. There is a problem that the copper wire according to the input is long.

In addition, since a function conversion for inputting English or special characters other than Korean must select a desired function by using the menu button, too many input buttons are used for text input, and thus there is a problem that a user may cause confusion in using a communication terminal. .

Accordingly, an object of the present invention is to provide a character input device and method for a communication terminal for performing Korean input by means of a fold input key and a comment input key. .

Another object of the present invention is to provide a character input device and method of a communication terminal for performing Korean, English or special character switching by a shortcut key.

First, by continuously pressing and holding the five numeric keys 300 of the communication terminal having the character input arrangement button configuration as shown in Figure 5 (S1100).

Subsequently, a consonant is input by selectively pressing any one of the basic consonant input buttons 1, 3, 7, 9, and 0 numeric keys (322, 324, 326, 328, 332) for initial entry among the syllables of the first, middle, and final syllables in Korean (S1102). ).

It is determined whether a comment or a double consonant is input according to a comment or a double number key 2, 4, 6, and 8 numeric keys 312, 314, 316 and 318 (S1104). When the comment or the double consonant is input, the inputted in the above step (S1102) A consonant of the syllable according to the comment or the overlapping consonant corresponding to the comment or the overlap of the consonant is configured and displayed on the liquid crystal display 420 (S1106).

On the other hand, if a comment or overlapping consonants are not input, the initial consonants of the syllables by the basic consonants input in step S1102 are configured to be displayed on the liquid crystal display 420 (S1108).

Subsequently, it is determined whether the vowel selection signal by the 5 digit key 300 is input (S1110), and when the vowel selection signal is input, the 2, 4, 6, and 8 numeric keys 312,314, 316, 318 used as a comment or overlap input button are input. Is operated as a vowel input key (S1112).

The vowels input by any one of the 2, 4, 6, and 8 numeric keys 312, 314, 316, and 318 form a neutral of syllables and are displayed on the liquid crystal display 420 (S1114).

Subsequently, according to the basic consonant input buttons of the 1, 3, 7, 9, and 0 numeric keys 322, 324, 326, 328, 332, it is determined whether a consonant signal for the final composition of the syllable is input (S1116), and the consonant signal for the final configuration of the syllable is input. If it is not input, it is determined that the syllable is composed of only initial and neutral, and the operation ends.

On the other hand, if the consonant signal for the final composition of the syllable is input in the above step (S1116), it is determined whether the comment or the double consonant signal according to the 2, 4, 6, 8 numeric keys (312,314, 316, 318), which is a comment or a fold input key, is input. It is determined again (S1118).

When the comment or the overlapped consonant signal is input, the completed syllable by the final configuration according to the comment or the overlapped consonant of the consonant input in the above step (S1116) is displayed on the liquid crystal display 420 (S1120).

On the other hand, when a comment or a double consonant signal according to the comment or the overlap button is not input, the completed syllable by the final configuration according to the consonant input in the above step (S1116) is displayed on the liquid crystal display 420 (S1122). .

Character input device of the communication terminal according to the present invention carried out through such a process is the terminal sound according to whether the consonants or vowels are input to the consonants of the subsequent syllables when two different consonants are input when configuring the final syllables Since the process of determining whether it is composed of a consonant or a consonant is common, a detailed description thereof will be omitted.

As described above, the character input device and method of the communication terminal according to the present invention assigns the consonant signal and the comment consonant signal to the 2, 4, 6, and 8 numeric keys of the communication terminals 0 to 9, and is located at the center. The basic vowel signal is assigned to the 5 digit keys, and the basic consonant, the single comment consonant of the basic consonant and the buzzer signal are assigned to the 1, 3, 5, 7, 9, and 0 numeric keys.

Also, 2, 4, 6, and 8 numeric keys to which the overlap consonant signal and the comment consonant signal are assigned are operated in association with the 5 numeric keys to allocate the remaining vowel signals other than the basic vowels.

Here, the residual vowel signals assigned to the 2, 4, 6, and 8 numeric keys for the input of the residual vowels are intuitively assigned according to the shape of the residual vowels.

Therefore, in the present invention, a comment consonant and a double consonant signal or a residual vowel signal are assigned to the 2, 4, 6, and 8 numeric keys, and the consonant signal and the vowel signal input are selected according to the input of the 5 numeric keys. It is effective to input Hangul.

In addition, the communication terminal allocates consonant and vowel signals respectively by three concentric circles according to Cheonjiin among the principles of Hangeul creation, and inputs the overlap and comment of the consonant signal in eight directions, that is, by eight strokes. There is also an effect that can reduce.

In addition, the residual vowel signals assigned to the 2, 4, 6, and 8 numeric keys have an intuitive arrangement according to the shape of the vowel signal, thereby shortening the copper wire for inputting Korean characters.

In addition, by assigning a 5 number key as a shortcut key for switching between Korean, English, or special character modes, and assigning 2, 4, 6, 8 number keys as special character selection moving keys, it is also possible to easily perform character input.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
