Abstract

A method for inputting a text message in a portable terminal is provided to allow a user to correct text conveniently through addition or substitution of alphabets in the text without the need to delete all of the text and input new text. If a user selects a text message input mode(211), a controller senses the text message input mode to display a text message input window. The controller determines whether an alphabet is inputted through a key input unit. If the alphabet is inputted, the controller checks the position of a cursor(215) and then determines whether the inputted alphabet is for text correction or text input. If the cursor is positioned adjacently to the last alphabet of a text message, the controller performs the text message input mode normally(223). If the cursor is positioned between alphabets of the text message, the controller performs a text correction mode(217).

 The present invention relates to a text message writing method of a mobile terminal, and more particularly, to a method for correcting an error text that may occur during text message writing.

The mobile terminal includes a short message service (SMS) capable of transmitting a message to the other party in addition to a voice call, and a multimedia message service (Multimedia Message Service) capable of exchanging various data such as voice, still image, and video as well as text; Provides a text messaging service such as MMS.

The text message service can deliver accurate information in a simple sentence, and can repeatedly check the message by recording and storing the message in the mobile terminal. In addition, the text message service has an advantage that the user can transmit the message at any time regardless of the operation state of the counterpart mobile terminal. As a result, more users are using text messaging services.

In the method of creating a text message in a mobile terminal, a text is generated by combining the basic letters input from the mobile terminal, and the written texts are gathered into a text message. However, if a letter is incorrectly entered by mistake of the user's key manipulation, the user must delete the wrong letter and type the letter again to create a new letter. This method is inconvenient to delete the written character and write a new letter even if only one letter is wrongly entered.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a method for correcting an error character generated during text message writing in a portable terminal with an input letter.

In order to achieve the above object, a text message modification method of a mobile terminal according to an embodiment of the present invention comprises the steps of: determining the position of a cursor when a letter is input when a text message is written; If the cursor is located between characters, generating the modified characters by matching the input letter with the characters input to the cursor, and displaying them as a character list; And modifying a character at which the cursor is located to a character selected from the character list.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible.

In the present invention, the term "portable terminal" refers to a terminal portable by a person and capable of wireless communication such as a mobile communication terminal, a personal digital communication terminal (PCS), a personal digital terminal (PDA), and a smart phone.

'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 in the case of Hangul is called Jamo, and in the case of English, each letter such as a, b, c, d, e is called Jamo. 'Text' is a combination of letters, and 'text message' is a collection of characters.

'Text message' means anything that can be written in text on a mobile terminal. For example, it can be a task, memo, phone number registration, photo file name, and so on. In the present invention, text messages such as SMS and MMS are described as examples.

'Pointer' is a mark indicating the position of a text when a text message is written in the mobile terminal. The pointer may move between characters to indicate the position of the character, or move down below the character to indicate the position of the character, or display the entirety of the character to indicate the position of the character. In the present invention, a method of modifying a text message proposes a method of determining based on the position of a pointer when checking a text to be modified. In the following description, it is assumed that the pointer is a cursor. In the present invention, a vertical cursor is described as an example of a cursor indicating a position of a character, but all types of cursors displayed on a portable terminal may be used. That is, when the cursor moves between characters with the vertical cursor to display the character position, the mobile terminal checks the neutrality, the finality of the character before the cursor, and the initiality of the character behind the cursor. If the cursor is a horizontal cursor and a square cursor, the mobile terminal can check the neutrality, the finality of the character in front of the cursor, and the initiality of the character where the cursor is located.

In the present invention, 'match' means that when the letters are corrected by the input letter, the letter is added to each letter to replace or replace the letter.

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

Referring to FIG. 1, the controller 110 controls each component of the mobile terminal 100 and controls interaction of each component. In the present invention, the control unit 110 controls to modify the text message. In other words, the controller 110 determines the position of the cursor when writing a text message and checks the character before the cursor. That is, when the text written at the time of writing the text message is Korean and the consonant inputted at the position of the cursor is the consonant, the controller 110 checks the finality of the character located in front of the cursor and the first consonant located behind the cursor. In addition, when the letter is input to the position of the cursor is a vowel, the controller 110 checks the neutrality and the finality of the character located in front of the cursor. The controller 110 confirming the created character displays the character generated by matching the alphabet input at the position of the cursor on the display unit 130 as a character list.

The key 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 key input unit 120 receives a character from the user and transmits the text to the controller 110.

The display unit 130 displays various information related to the state and operation of the mobile terminal 100. In particular, the display unit 130 displays characters input when a text message is created under the control of the controller 110, and displays a list of characters created by matching the letters to each character when the letter is input at the cursor position.

The storage 140 stores various programs for controlling general operations of the mobile terminal 100 and various data generated during the operation of the mobile terminal 100. In particular, the storage unit 140 stores a program such as a combination code for generating letters by matching letters with each letter when the letter is input at the cursor position.

The communication unit 150 performs a frequency communication function between the mobile terminal 100 and the base station. The communication unit 150 may include a duplexer for separating transmission and reception functions, a transmitter for up-converting a frequency of a transmission signal, and a receiver for down-converting a frequency of a reception signal. In particular, the communication unit 150 transmits a text message under the control of the control unit 110.

2 is a flowchart illustrating a text message writing method according to an embodiment of the present invention.

Referring to FIG. 2, when the user selects a text message writing mode, the controller 110 detects the text message writing mode in step 211, displays a text message input window, and then moves the key input unit 120 in step 213. Determine if the letter is entered. When the letter is input, the controller 110 checks the position of the cursor in step 215 to determine whether the input letter is a letter for letter correction or a letter for letter writing. In the present invention, it is determined whether the text is modified by the position of the cursor while creating the text message. That is, when the letter is input while the cursor is positioned between the letters, the controller 110 may correct the letters located before and after the cursor by using the input letter. If the cursor is adjacent to the last character of the text message, the normal text message writing mode is performed. Therefore, when the cursor is adjacent between the characters in step 215, the controller 110 performs the character modification mode in step 217.

3 is a detailed flowchart illustrating a text correction method executed in step 217 of FIG. 2 according to an embodiment of the present invention. 4A through 4D are exemplary views illustrating a method of modifying a Hangul text message executed in FIG. 3. Also, FIG. 5A to FIG. 5C are diagrams illustrating a method of modifying an English text message executed in FIG. 3.

Referring to FIG. 3, the controller 110 that detects that the cursor is adjacent between characters checks the type of the character created in step 310. The character type may be any character that can be used in the mobile terminal. In the present invention, it is assumed that the character is written in Korean and English.

If the character type identified in step 310 is a Hangul text message as shown in FIG. 4A, the controller 110 determines the input alphabet type in step 320. In this case, the type of the Jamo type may be classified into vowels and consonants. 4A illustrates an example in which an error occurs in 'nucleus bridge' and 'ilmer', in particular, the 'nuclear bridge' is an example in which an error is generated in a vowel, and the 'ilmer' is an example in which an error occurs in a consonant. to be.

If the input letter type is vowel ('ㅏ') in step 320, the controller 110 displays the character ('nucleus' placed in front of the cursor among the characters adjacent to the cursor ('nucle' and 'bridge') in step 331). Check the neutral ('ㅐ') and the finality ('ㄱ') of '). In step 333, the controller 110 confirming the neutral ('ㅐ') and the finality ('ㄱ') of the character ('core') inputs the neutral ('ㅐ') and the finality ('ㄱ') of the character. Matched vowels ('ㅏ') to produce a first modified character ('school') and a second modified character ('Haegashi'). Thereafter, the controller 110 lists the generated first and second modified characters as a character list and displays the pop-up window on the display unit 130. In operation 350, the controller 110 checks the corrected character selected from the first corrected character and the second corrected character of the displayed character list. In this case, when the corrected character displayed on the popup window is selected, the controller 110 detects this in step 350, corrects the character in which the error occurs in step 360 with the selected corrected character, and returns to step 219. An error correction method of the Hangul text message according to an embodiment of the present invention will be described with reference to FIGS. 4A to 4D.

For example, when the letter 'ㅏ' for correcting the 'nucleation bridge', which is the cursor position shown in FIG. 4A, is input through the key input unit 120, the controller 110 confirms that the input letter 'ㅏ' is a vowel. Thereafter, the controller 110 checks the neutral 'ㅐ' and the final 'B' of the character 'nucleus' located in front of the cursor. In addition, the controller 110 generates a first modified character 'hak' by replacing the identified 'neutral' of the 'nucleus' with the input letter ''. The controller 110 inserts the input letter '모' into the final character 'a' of the identified character 'nucleus' to generate a second modified character 'harm'. Thereafter, the controller 110 generates a list of letters consisting of 'school' and 'Haegyo bridge' by combining the letters 'bridge' located behind the cursor with the letters 'hak' and 'sunga'. In addition, the controller 110 controls the display unit 130 to display the generated character list as a pop-up window as shown in FIG. 4B. Subsequently, when the user selects 'school' in the displayed pop-up window, the controller 110 detects this and converts the character 'core bridge' adjacent to the cursor to the selected character 'school' and displays it as shown in FIG. 4D.

Here, the character list is described as an example of being composed of the first modified character and the second modified character, but all the modified characters that can be generated according to the input vowel may be displayed as the character list. Although not shown in the drawings of the present invention, when the user inputs a 'samija', a case of incorrectly written 'three characters' because 'ㅣ', which is a collection of letters 'S.' The user inputs the letter 'ㅣ' to correct it, and the controller 110 confirms that the input letter 'ㅣ' input through the key input unit 120 is a vowel. After that, the controller 110 checks the neutral 'ㅏ' and the final letter 'ㅁ' of the character 'three' located in front of the cursor. The control unit 110 generates the first modified character 'sim' by replacing the identified 'neutral' 'neutral' with the input letter 'ㅣ', and also the input letter 'ㅣ' and the The neutral 'ㅏ' is synthesized to generate a second correction character 'sam'. Then, the inserted letter 'ㅣ' is inserted into the identified character 'sam' of the finality 'ㅁ' to generate a third modified character 'Sami'. Thereafter, the controller 110 combines the characters 'sim', 'sam' and 'sami' with the characters 'characters' located after the cursor to form the characters 'simmon', 'samja', and 'sami'. Create a list. The controller 110 controls the display unit 130 to display the generated character list as a popup window. Thereafter, when the user selects 'samija' from the character list through the key input unit 120, the controller 110 converts the 'three characters' into 'samija' and displays it on the display unit 130.

On the other hand, if the type of consonant is consonant ('ㅇ') in step 320, the controller 110 displays the character ('day') located in front of the cursor among the characters ('one' and 'mer') adjacent to the cursor in step 335. ) And the initial consonant ('ㅁ') of the character ('mer') located behind the cursor. The control unit 110 confirms the finality ('ㄹ') and the initiality ('ㅁ') of the letters ('day' and 'mer') at step 337, respectively. ') Matches the input consonant (' o ') to generate a first correction character (' inger ') and a second correction character (' Japanese '). Thereafter, the controller 110 lists the generated first and second modified characters as a character list and displays the pop-up window on the display unit 130. In operation 350, the controller 110 checks the corrected character selected from the first corrected character and the second corrected character of the displayed character list. In this case, when the corrected character displayed on the popup window is selected, the controller 110 detects this in step 350, corrects the character in which the error occurs in step 360 with the selected corrected character, and returns to step 219. An error correction method of the Hangul text message according to an embodiment of the present invention will be described with reference to FIGS. 4A to 4D.

For example, when the letter 'o' for correcting 'ilmer' is input through the key input unit 120, the controller 110 confirms that the input letter 'o' is a consonant. After that, the controller 110 checks the finality of the letter 'yl' and the initial 'ㅁ' of the character 'il' located in front of the cursor. The controller 110 generates the character 'ying' by replacing the confirmed character 'l' with the final letter 'l' with the input letter 'o' and generates the initial character 'ㅁ' of the identified character 'mer'. The letter 'word' is generated by replacing the input letter 'o'. The controller 110 generates a list of characters consisting of a first modified character 'inger' and a second modified character 'Japanese' by combining the generated characters 'ing' and 'er' with the characters where the cursor is located. . In addition, the controller 110 controls the display unit 130 to display the generated character list as a pop-up window as shown in FIG. 4B. Subsequently, when the user selects 'Japanese' in the displayed pop-up window, the control unit 110 detects this and converts the adjacent character 'ilmer' to the selected character 'Japanese' and displays it as shown in FIG. 4D.

However, if the type of the character identified in step 310 is an English text message as shown in FIG. 5A, the controller 110 checks adjacent characters 'a' and 't' adjacent to the cursor in step 341. 5A illustrates an example in which 'a' occurs in 'togather'. In step 343, the controller 110 confirms that the cursors adjacent characters 'a' and 't' are replaced with or inserted into the input letter 'e'. Generates the first modification character 'et' and the second modification character 'aet'. Thereafter, the controller 110 lists the generated first and second modified characters as a character list, and displays the character list as a pop-up window by controlling the display unit 130. In operation 350, the controller 110 checks the corrected character selected from the first corrected character and the second corrected character of the displayed character list. In this case, when the corrected character displayed on the popup window is selected, the controller 110 detects this in step 350, corrects the character in which the error occurs in step 360 with the selected corrected character, and returns to step 219. An error correction method of the English text message according to an embodiment of the present invention will be described with reference to FIGS. 5A to 5C.

For example, when the letter 'e' for modifying 'a' is input through the key input unit 120 at the cursor position 'togather' shown in FIG. 5A, the controller 110 may display the letter 'a' located in front of the cursor. And the character 't' located after the cursor. Thereafter, the controller 110 generates the first modified letter 'e' by replacing the checked letter 'a' with the inputted letter 'e', and also the input letter 'e' before the checked letter 't'. Add 'to create a second modification character' et '. The controller 110 combines the generated letter 'e' with the letter 't' located after the cursor, and combines the letter 'et' with the generated letter 'et' with the letter 'a' located in front of the cursor. Create 'aet' Next, the controller 110 lists the generated characters as a character list and controls the display unit 130 to display the character list as a popup window as shown in FIG. 5B. Subsequently, when the user selects 'et' in the displayed popup window, the controller 110 detects this and converts the adjacent character 'at' to the selected character 'et' and displays the same as in FIG. 4D.

FIG. 6 is a flowchart illustrating a method of modifying an English text message, in particular in the method of text editing executed in step 217 of FIG. FIG. 7 is an exemplary diagram illustrating a method of modifying an English text message executed in FIG. 6.

When the controller 110 determines the type of the text in which the text message is written in step 310, if the type of the checked text is an English text message as illustrated in FIG. 7, the controller 110 determines that the cursor is adjacent to the text in step 611. Check ('f' and 't'). 7 illustrates an example in which an error occurs because 'f' is incorrectly input in 'togfther'. In operation 613, the controller 110 confirms that the cursors have adjacent characters 'f' and 't', and determines whether the input letter is input from a key mapped with the character. If the key mapped with the character is input, the controller 110 displays the character mapped after the character in step 615. In step 617, the controller 110 determines whether the key mapped with the letter is input again. If the key mapped with the character is not input again, the controller 110 returns to step 219. An error correction method of the English text message according to another embodiment of the present invention will be described with reference to FIG. 7.

For example, when a key corresponding to the letter 'e' for modifying 'f' is input through the key input unit 120 at the cursor position 'togfther' shown in FIG. 7, the controller 110 is located in front of the cursor. Note the character 'f' and the character 't' located after the cursor. Thereafter, when the input key is a key mapped to the letter 'f', the controller 110 converts the letter 'f' to a letter 'd', and if the key mapped to the letter 'f' is input again, the letter Convert 'f' to the letter 'e'. This method uses a method that maps alphabetic characters to each key of key input unit. For example, the numeric keys 3 are mapped with the letters 'd, e, f'. When you write an English text message, press the numeric key 3 once to enter the letter 'd', or press twice to enter the letter 'e' and three times. Pressing it enters the letter 'f'. Therefore, when the cursor checks the adjacent English characters, the controller 110 should determine how many times a key mapped with the English characters is inputted to display the input English characters.

On the other hand, if the key to which the character is mapped is not input in step 613, the controller 110 replaces or inserts the checked character with the inputted letter in step 619 to generate a first modified character and a second modified character. do. Thereafter, the controller 110 lists the generated first and second modified characters as a character list, and displays the character list as a pop-up window by controlling the display unit 130. In operation 619, the controller 110 checks the corrected character selected from the first corrected character and the second corrected character of the displayed character list. In this case, when the corrected character displayed on the popup window is selected, the controller 110 detects this in step 621, and in step 623 corrects the character in which the error occurs with the selected corrected character and returns to step 219.

 After that, the control unit 110 returns to step 219 to determine whether a text message creation completion is selected. When the text message creation completion is selected through the key input unit 120, the controller 110 detects this as a text transmission selection and transmits the created text message to a number set by the user in step 221.

However, when the letter is input in step 215, if the cursor is located at the last letter, the controller 110 determines that the letter is not a letter for correcting the letter, and performs letter writing in step 223.

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 embodiment, and various modifications can be made by those skilled in the art without departing from the gist of the present invention attached to the claims. will be.

According to the present invention, a user may modify a character by adding or replacing a letter to a character to be edited, without having to delete all the characters and then newly writing the character in order to correct the wrongly written character in the text message.
