Method for controlling inputted character

The present invention relates to a method of distinguishing input characters.

In particular, the present invention relates to a method of determining whether an input character is completed when a Korean character is input in a terminal so that a voice signal for the character is clearly output.

Recently, various ideas for outputting Hangul characters inputted by voice have emerged. However, in the process of inputting characters, any character (consonant or vowel) can be divided into one character and outputted as a voice. There is no clear description of whether this is the case.

The present invention has been made to solve the above problems, and the object of the present invention is to provide a method for supporting the Korean characters to be clearly output by voice by clearly determining the completion time of the character input of the Hangul input by the user. have.

According to an embodiment of the present invention for realizing the above object, in the method of distinguishing the input characters, the user inputs the Hangul input by the user as a voice. A character input determination step of determining whether the character is an input-completed character according to a combination relationship of initial, neutral, and longitudinal when forming; If the character is an input-completed character, it provides a method for distinguishing input completed characters, characterized in that comprises a notification means output step of outputting a set notification means for informing completion of the input of the character.

In the embodiment, the character input determination step, when another consonant is input after the consonant corresponding to the finality is input, the second input consonant if the second input consonant corresponds to the first consonant of the next character It is characterized by judging the previous character as one character.

In the embodiment, the character input determination step, when another consonant is input after the consonant corresponding to the finality is input, if the second input consonant is included in the finality of the corresponding character until the second input consonant It is characterized by judging by one character.

In the embodiment, the character input determination step, when the vowel is continuously input two or more times, if the last input vowel is not included in the vowel of the corresponding character to determine before the last input vowel as one character It is characterized by.

In the embodiment, the character input determining step is characterized in that, if the consonant is input after the neutral is input and the vowel is subsequently input, before the consonant is determined as one character.

In the embodiment, the notification means of the notification means output step, characterized in that it comprises one or more of voice, sound, light, vibration.

These objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

1 is a schematic configuration diagram of a mobile communication terminal according to an embodiment to which the present invention is applied, FIG. 2 is an embodiment diagram of a keypad for explaining the present invention, and FIGS. 3 and 4 are diagrams for explaining the present invention. Example Screens and flowcharts.

In particular, the present invention is a method for distinguishing the input completed character for the Hangul characters input by the user, it can be applied to all terminals equipped with a key input unit for inputting the Hangul characters, the following is a mobile communication terminal This will be described as an example.

The mobile communication terminal to which the present invention is applied includes a component as shown in FIG. 1, and a brief description of each component is as follows.

A key input unit 10 which is composed of a plurality of numbers and function keys and generates key data corresponding to a key selected by the user and transmits the key data to the control unit 20, a control unit 20 which performs overall operation control of the terminal, A radio frequency transmitter / receiver unit 30 for amplifying and filtering a radio frequency signal transmitted / received through an antenna and performing signal modulation / demodulation, and a display unit 40 for displaying information signals generated during an operation and operation of a terminal; The memory unit 50 stores data received through the radio frequency transmitter / receiver 30 and key data input through the key input unit 10, and a microphone and a speaker under operation control of the controller 20. The mobile communication terminal includes a voice processing unit 60 that performs modulation / demodulation of input / output voice signals.

The key input unit 10 includes a keypad for inputting Korean characters, and the controller 20 includes an algorithm of the present invention for distinguishing input characters when Korean characters are input.

Hangul is composed of consonants and vowels to form a single character (one letter).

For example, the letter 'sword' can be divided into 'b' as a consonant, 'ㅓ' as a neutral, and 'ㅁ' as a finality, and some characters do not include a star.

Therefore, in order to input Hangul, consonants and vowels must be combined, and each key of the keypad is assigned one or more consonants or vowels so that key data of the consonants or vowels is output according to the user's input.

2 illustrates an embodiment of a keypad to which consonants or vowels are assigned.

Depending on which Korean character input method is adopted by the terminal, a key to which consonants or vowels are assigned is different from the keypad. Hereinafter, the keypad of FIG. 2 will be described as an embodiment.

Consonants or vowels are printed one by one (or two) on the keys of the keypad as shown in FIG. 2, and the stroke may be added by '*', and the consonants may be input by entering '#'.

For example, the '1' key is printed with the consonant 'ㄱ', 'ㅋ' enters the '1' key, enters the '*' key, and 'ㄲ' enters the '1' key, followed by '#' Type '.

When inputting the Hangul according to the Hangul input method in the terminal equipped with a keypad as shown in Figure 2, the method of distinguishing the input completed characters are as follows.

1) Another consonant is input after the consonant corresponding to the final consonant is input.

1-1) If the second input consonant corresponds to the first consonant of the next character, the second input consonant is determined as one character before the second input consonant.

When the user enters the letter 'when', the user's letter 'o', the neutral 'ㅓ' and the last word 'b' are entered, and the 'word' is formed.

If the final character 'ㅁ' is input and 'ㅈ' is input, the second input 'ㅈ' is not included in the final character of the first character and is moved to the first character of the next character.

In this case, it is determined that the character input before 'ㅈ' is regarded as an input completed character, and a voice signal corresponding to 'un' is output through the speaker.

The 'un', which is an input character, is searched in a mapping table to output a corresponding voice signal.

The mapping table stores voice signals for all characters that can be formed by combining consonants and vowels.

After it is determined that the input is completed, the voice signal may be output as described above, or a notification means such as sound, light, or vibration may be output to notify the user that the corresponding character is completed.

When the sound is set as the notification means, a beep sound may be output. When the light is set as the notification means, the LED or the backlight of the keypad may be blinked.

Alternatively, two or more notification means may be output at the same time.

1-2) When another consonant is input after the consonant corresponding to the finality is input, if the second input consonant is included in the finality of the corresponding character, the second input consonant is determined as one character. .

When you enter the letters 'sit', enter the initial 'ㅇ' and the neutral 'ㅏ' and the final 'b' and 'ㅈ' to form the 'sit' character.

After entering the finality of 'b' and 'ㅈ' and entering 'ㅇ' of the next character, 'b' and 'ㅈ' are included in the finality of the first character.

In other words, this case is the case where the finality consists of two consonants.

In this case, the character inputted before the letter ㅇ, which is the consonant of the next character, is determined as a completed character, and a voice signal corresponding to 'sit' is output through the speaker.

2) A vowel is entered more than once in a row.

If the last vowel that is input is not included in the vowel of the corresponding character, it is determined as one character before the last input vowel.

In order to enter the 'why' character, you need to enter 'ㅇ' which is a consonant and 'ㅗ', 'ㅏ', and 'ㅣ' as neutral.

After entering three vowels, if you enter another vowel, the last vowel is not included in the `` why '' vowel. Voice signal corresponding to 'is output through the speaker.

3) Consonants and vowels are input after neutral is input.

Before the consonant is determined as one character.

Referring to Figure 4, in order to enter the character 'mother' after entering the first letter 'ㅇ' and the neutral 'ㅓ' (S10, S20), the first letter of the second letter 'ㅁ' Input (S30).

In this case, the 'ㅁ' may be recognized as the last character of the first letter and may be formed of a letter 'Um'. However, when 'ㅓ', which is the neutral of the second letter, is input (S40), the 'ㅁ' is the first letter of the second letter. Is moved to.

As shown in FIG. 3, as the letter 'm' is formed, 'ㅁ', which is a vowel, is moved to form a letter of 'mother' by moving to the beginning of the second letter.

Therefore, it is determined that the character is inputted before 'ㅁ', and if the 'er' character is searched for in the mapping table (S50), a voice signal corresponding to the character is output through the speaker (S60).

As described above, when the vowel of the second character is input, the input consonant (regarded as the finality) is moved to the first consonant of the second character when the vowel of the second character is input.

4) A key is used to move the cursor on the display.

Before the key input is determined as one character.

In this case, the characters inputted by the user are distinguished.

When entering the character 'mother', as described above, 'ㅇ', 'ㅓ', 'ㅁ', 'ㅓ', etc. may be entered sequentially, but after entering 'ㅇ' and 'ㅓ' If you input a key to move and input 'ㅁ', 'ㅁ' is directly input as the first character of the next character.

The key for moving the cursor may be a direction key, an enter key, a space key, or the like.

The Korean input as described above may be used when inputting a name of the other party when registering a phone book in the mobile communication terminal or when writing a text message.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, when the user inputs Hangul in any terminal, according to the present invention, when the character input completion time of the Hangul input by the user is clearly determined, the voice can be output.
