Description

Character input method of terminal {METHOD FOR INPUTTING LETTER IN TERMINAL}

The present invention relates to a character input method in a terminal, and more particularly, to a method of inputting Hangul using vowels in a terminal.

As modern science develops, various handsets are being developed. These terminals have functions to store or exchange data. Accordingly, users can create documents, messages, mails, and the like using various terminals, and can exchange documents, messages, mails, and the like with other users.

When creating a document, a message, an e-mail, etc. in the terminal, the user inputs a phoneme through the keypad, and in the terminal, the phoneme is combined and displayed as one character. The keypad provided in the terminal such as a computer combines phonemes one by one, and when the user inputs Hangul, the user inputs a combination of phonemes to be input. However, in a device in which a keypad is limited in size, such as a mobile terminal, several phonemes are combined in the keypad.

When only a vowel is input from a phoneme when inputting a character using Hangul, the terminal does not recognize the input vowel as a character but recognizes that a typo is generated. In this case, it is inconvenient for the user to delete the input phonemes or characters and re-enter them.

An object of the present invention for solving the above problems is to provide a method for automatically inputting a completed character when the Hangul vowel input in the terminal.

Another object of the present invention is to provide a method for inputting a character using a vowel in a Hangul terminal.

In order to achieve the above object, the character input method of the terminal according to an embodiment of the present invention comprises the steps of determining whether the alphabet is input in the Hangul character writing mode; Determining whether a consonant exists in the initial consonant of a character in which the vowel is located if the inputted vowel is a vowel; And if the consonants do not exist, adding and displaying the consonants set in the initial consonant.

According to the present invention, when a character is input in the terminal, a character in which the consonant 'o' is displayed on the initial consonant may be automatically input even without separately inputting the consonant 'o'. Also, even if only a vowel is input, the consonant 'ㅇ' is automatically displayed, so the user may not modify the letter with only the vowel.

In the present invention, the terminal refers to an information processing device capable of creating or storing data, and when the communication unit 110 is provided, it refers to a device that can exchange data with another terminal. The terminal may be a computer, a laptop, an mp3, a digital camera, a portable terminal, or the like. Here, the terminal will be described as an example of a portable terminal.

'Zamo' is a single letter that can be written down by dividing one syllable into consonants and vowels. In the present invention, each letter such as a, b, c, ㅏ, ㅑ is a Jamo alphabet. Also, 'letter' is a letter consisting of letters.

The 'automatic consonant addition function' refers to a function for automatically adding consonants set when only a vowel is inputted when a character is input in the mobile terminal. The consonant set here may be set to a consonant included in a character frequently used by the user.

'Character writing mode' refers to a mode in which a character can be input in the terminal. For example, it includes document writing, memo, to-do, and file name storage. In the case of a mobile terminal, a text message (short message, multimedia message, etc.) is further included.

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

1 is a block diagram showing the configuration of a terminal according to the present invention.

Referring to FIG. 1, the terminal includes a communication unit 110, an input unit 120, a control unit 130, a display unit 140, and a storage unit 150.

The communication unit 110 performs a communication function between the terminals. The communication unit 110 may include a duplexer for separating transmission and reception functions, a transmitter for up-converting the frequency of the transmission signal, and a receiver for down-converting the frequency of the received signal.

The input unit 120 includes input keys for inputting numbers or letters and function keys for setting various functions. The function keys may include direction keys, side keys, shortcut keys, and the like, which are set to perform specific functions.

The controller 130 controls each component of the terminal, and controls the interaction of each component. Therefore, when the character is input through the input unit 120, the controller 130 determines whether the input character is a vowel. If the input vowel is a vowel, the controller 130 determines whether there is a consonant in the consonant of the character where the input vowel is to be located, and if there is no consonant, the controller 130 may automatically add a consonant set before the input vowel. Here, the set consonants will be described using 'ㅇ' as an example.

The display unit 140 displays various information related to the state and operation of the terminal. In particular, the display unit 140 may display a character input through the input unit 120 under the control of the controller 130.

The storage unit 150 stores various programs for controlling general operations of the terminal and various data generated during operation of the terminal.

When a character is input through the input unit 120 in the terminal having such a configuration, the controller 130 may control the display unit 140 to display the input character. In addition, when the input character is a vowel, the controller 130 determines whether there is a consonant in the initial consonant of the character in which the input vowel is located. If there is no consonant in the place of the initial, the controller 130 may add the consonant 'ㅇ' and display it on the display unit 140.

2 is a flowchart illustrating a character input method according to an embodiment of the present invention. 2 will be described with reference to FIGS. 3A to 3G. 3A to 3G are diagrams illustrating screens illustrating a text input method according to the present invention.

In order to automatically add consonants in the text writing mode, the user sets an automatic consonant adding function through the input unit 120 in the portable terminal 100. The automatic consonant addition function may be set through a menu, and the automatic consonant addition function may be set by using a function key provided in the input unit 120. Accordingly, when only the vowel is added in the text writing mode in the mobile terminal 100, the consonant may or may not be added depending on whether the automatic consonant addition function is set.

The mobile terminal 100 assumes that the automatic consonant addition function is set by the user. Referring to FIG. 2, when the user selects the text writing mode through the input unit 120, the controller 130 detects this in step 210 and switches the mode of the terminal to the text writing mode. The text writing mode may be a mode for writing a document in the terminal, and may include a mode for inputting a file name when storing a file. In the case of a mobile terminal, the text writing mode may include a message writing mode for writing a text message. Next, the controller 130 displays the text input window on the display unit 140 in step 215. After that, when the controller 130 inputs the letter of the character to be input by the user through the input unit 120 in step 220, the controller 130 determines whether the letter is input in step 225. If the input alphabet is a consonant, the controller 130 displays the input character in step 250. However, if the input vowel is a vowel, the controller 130 determines whether a consonant exists in the initial consonant of the character where the input vowel is located in step 230. In a text, letters consist of primary, neutral, and final. First and last are composed of consonants, and neutrals are composed of vowels. Therefore, when the vowel is input, the controller 130 must determine whether there is an input consonant in the place of the initial.

If there is no consonant in the initial consonant, the controller 130 determines whether the next consonant is input through the input unit 120 in step 235. When the next letter is input, the controller 130 adds a consonant 'ㅇ' to the initial consonant of the letter where the vowel inputted in step 245 is located. In addition, the controller 130 displays a character in which the consonant 'ㅇ' is added to the initial consonant of the character including the input vowel in operation 250.

On the other hand, if the next letter is not input, the controller 130 determines whether a character input completion signal is input in step 240. In other words, when the cursor indicating the position where the letter is displayed is moved, the controller 130 recognizes this as a character input completion signal. Also, even if the next letter is not input for a preset time after the letter is input, the controller 130 recognizes this as a character input completion signal. The controller 130 recognizes this as a character input completion signal even if the next letter is input after the input vowel.

When the character input completion signal is input, the controller 130 adds the vowel 'O' to the initial letter of the character where the vowel inputted in step 245 is located. In addition, the controller 130 displays a character in which the consonant 'ㅇ' is added to the initial consonant of the character including the input vowel in operation 250.

Steps 235 to 250 will be described in detail with reference to FIGS. 3A to 3F.

3A to 3B are exemplary views illustrating a case in which a character to be input for the first time includes a consonant 'O'. When the text writing mode is selected through the input unit 120, the controller 130 displays a text input window on the display unit 140. When the user inputs the vowel 'ㅗ' through the input unit 120 to input the letter 'o', the controller 130 detects this and displays the vowel 'ㅗ' on the display unit 140 as shown in FIG. 3A. Then, the user moves the cursor displayed at the position where the letter 'ㅗ' is input through the input unit 120 to input the next character. Then, the controller 130 detects the cursor movement as a character completion signal. As shown in FIG. 3B, the controller 130 adds a consonant 'ㅇ' to the initial place of the vowel 'ㅗ' and displays the letter 'O'.

'을 표시부(140)에 표시한다. 제어부(130)는 모음 'ㅡ' 다음에 자음 'ㄴ'이 입력되었음을 감지하고 3d와 같이 문자 '

'의 초성에 자음 'ㅇ'를 첨부하여 문자 '은'으로 표시한다. 3C to 3D are diagrams illustrating screens illustrating screens when a character including consonants 'ㅇ' and finality is input. For example, when the user wants to input 'today' on the terminal. The user inputs the character 'today' through the input unit 120 and then moves the cursor indicating the position where the character is to be displayed. Then, the controller 130 detects the cursor movement and determines it as a character input completion signal. Next, the user inputs the vowel 'ㅡ' through the input unit 120 to input the letter 'silver', and then inputs the consonant 'ㄴ'. The control unit 130 detects this, and the character 'inputted through the input unit 120'

'Is displayed on the display unit 140. The controller 130 detects that the consonant 'b' is input after the vowel 'ㅡ' and the letter 'as shown in 3d.

The consonant 'ㅇ' is added to the consonant of 'and the letter'is'.

'을 입력한 다음, 문자의 위치를 표시하는 커서를 옆으로 이동시키면, 제어부(130)는 이를 문자 입력 완료 신호 로 감지한다. 그리고 제어부(130)는 문자 '

'의 초성에 자음 'ㅇ'을 추가하여 표시할 수도 있다. In addition, the user through the input unit 120 through the letter '

After inputting ', moving the cursor displaying the position of the character to the side, the controller 130 detects this as a character input completion signal. And the controller 130 is a letter '

You can also add the consonant 'ㅇ' to the consonant of '.

3E to 3G are diagrams illustrating screens illustrating screens when characters including consonants 'o' in a consonant are consecutively input.

 Referring to FIGS. 3E to 3G, for example, when a user wants to input characters 'Y' and 'E' consecutively. After the user inputs 'Rain today,' the user moves the cursor through the input unit 120 to write a space, the controller 130 detects this as a text input completion signal. The controller 130 waits for input of the next character. When the user inputs the collection 'ㅣ' through the input unit 120, the control unit 130 detects this and displays the collection 'ㅣ' on the display unit 140. The controller 130 determines whether a text input completion signal is input through the input unit 120. Here, the character input completion signal is when a certain time has passed after the vowel 'l' is input or when the vowel 'ㅔ' is input after the vowel 'l'. The controller 130 detects such a case as a text input completion signal. When the character input completion signal is input, the controller 130 adds a consonant 'O' to the initial place of the vowel 'l' and displays it on the display unit 140. Next, the controller 130 determines whether a character input completion signal is detected in the next input vowel 'ㅔ'. When the character input completion signal is detected, the controller 130 adds a consonant 'O' to the initial place before the vowel 'ㅔ' and displays the letter 'E' on the display unit.

Referring back to FIG. 2, in operation 255, the control unit displaying the character generated by combining the input letters on the display unit 140 determines whether a document creation completion signal is received through the input unit 120. In other words, the user inputs all the characters to be input, and then inputs a confirmation key provided in the input unit 120 to execute a desired function. Then, the controller 130 detects this as a document creation completion and performs the corresponding function in step 266. That is, when the text writing mode is the text message writing mode of the mobile terminal, when the controller 130 detects the completion of the text writing, the controller 130 transmits the message using the created texts. Alternatively, if the character creation mode for storing a file or the like, the controller 130 stores the created character as a file name when detecting the completion of the character creation. The method may further include a process of correcting a written character in determining whether a document creation completion signal is received. Accordingly, a user may correct a typo or an incorrectly input character in the input character.

In the present invention, when the consonant does not exist in the initial consonant of the letter, the consonant 'ㅇ' is added as a method of displaying the letter. However, if there are no consonants in the consonant of the character where the vowel is located, the input consonants may be set differently according to the user. The user may store the frequently used consonants so that the stored frequently used consonants are displayed when there is no consonant input in the first letter of the next letter after the vowel is input.

In the present invention, when there is no consonant in the initial consonant of the letter, when the vowel is input, the consonant is automatically added and the method of completing the letter has been described. In addition, in the method of adding automatic consonants, the controller 130 may not add the set consonants even when there are no consonants in the initial consonants of letters when the vowel input is selected by the user. For example, it is assumed that a toggle key for text input is provided in the input unit 120 of the mobile terminal 100. After the user inputs a toggle key, inputs a vowel or inputs a vowel, and then enters a toggle key, the controller 130 detects this and displays only the vowel without displaying the consonant automatically added to the character. .

In addition, even in the case of automatically added consonants, when the user inputs a cancel key or a delete key provided in the input unit 120, the controller 130 may cancel the added consonants and display only a vowel. In this case, when the cancel key or the delete key is input twice, the character may be deleted. Here, the method of automatically canceling the consonants added may be performed differently according to the setting method. For example, if the cancel key is input once, the character is deleted, and if the cancel key is input twice, it is possible to delete only the consonants automatically input. Accordingly, the controller 130 may selectively add consonants by a toggle key or a cancel key input to the input unit 120, or selectively add consonants by selecting an option menu.

In the above, specific preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention attached to the claims. .
