A flowchart for describing an embodiment of a text correction method according to the present invention.

As shown in FIG. 2, in the apparatus (terminal) of the present invention, two or more characters are marked on one key button, and the key input unit 10 outputs key data for the key button selected by the user. And a key data processor 20 for executing overall processing according to the key data input through the key input unit 10, a display unit 30 for outputting a signal according to the key data input through the key input unit 10, and Each menu screen includes a key map defining a function of a key used for each menu screen, and a memory unit 40 for storing the input data and the like.

The device of the present invention can be applied to all terminals capable of text input.

The key input unit 10 includes a 'modification key', and the modification key is a function key for changing the character to be modified into another character of the key button marked with the character.

For example, when the user wants to change the 'q' character previously input by the user in the key input unit illustrated in FIG. 3 to the 's' character, the cursor is placed before or after the 'q' character or on the 'q' character. Is located and can be changed by inputting a modification key. If the '7' key is pressed once, 'r' is pressed, and if pressed once, it is changed to 's' character.

That is, it is not necessary to press 'erase' to delete the 'q', and to find '7' to press 's' to press 's'.

As shown in FIG. 3A, when the modification key is in a text input mode, a keymap is set so that one of the keys already existing in the key input unit 10 functions as a modification key, so that the modification key can be used by the user. have. In FIG. 3A, a hot-key for wireless Internet access, which is positioned among moving keys for moving up, down, left, and right, is used as a modification key 110 in a text input mode.

In such a case, since the modification key can be simply used by upgrading the software of the terminal for keymap setting, it can be immediately introduced into the terminal currently used.

In addition, as shown in FIG. 3B, the modification key 100 may be provided in the key input unit 10 separately.

In FIG. 3B, two modification keys, one on each side, are provided to allow a user to conveniently use the modification key 100, but only one modification key may be provided.

When the modification key is input, the key data processing unit 20 checks where the current cursor is located according to a preset algorithm and changes one of the character in front of the cursor, the character behind the cursor, or the character in which the cursor is located.

When the character is modified, the character to be modified is set to be changed in the forward direction or the reverse direction of the marked key button, which may be set by the user.

Referring to FIG. 4, the text modification method using the modification key of the present invention will be described in detail.

First, since the modification key can be used in a text input mode such as sending a short message, registering a phone book (address book), or setting a standby screen, check whether the text input mode is used (S1).

As shown in FIG. 3B, the terminal is provided with a modification key separately, and in FIG. 3A, a keymap may be set such that a specific key among the existing keys functions as a modification key in the text input mode.

After the character is input in the text input mode (S2), if there is a character to be modified by the user among the input characters (S3), the cursor is positioned immediately after the character to be modified (S4).

Since the position of the cursor is specified in advance in which position of the character is to be modified, the cursor may be positioned at the position. In FIG. 4, the character immediately before the cursor is modified.

When the cursor is positioned at the corresponding position and a correction key is input (S5), the key data processing unit 20 determines which numeric key the character in front of the cursor is on, and is displayed next to the character in the numeric key in which the character is indicated. Let the character be changed to a character.

The user may be set to change the next (forward) or forward (reverse) character of the character from the numeric key in which the character is indicated.

If the character is corrected to the desired character by entering the modification key once (S6), if there is a character to be input further, the character is input (S7) and the process returns to the process S2.

If the correct key is input once but the character is not corrected to the desired character (S6), the correct key is input until the character is changed to the desired character by returning to step S5, such as inputting the correct key once more.

If the character to be modified is corrected to the desired character and there is no more character to input, the text input is terminated (No in S7).

As an example, a case of modifying z input through the key input unit as shown in FIG. 3 to y will be described in comparison with the conventional art.

Conventionally, to erase z, press the 'Erase' key once and press the 9 key labeled 'y' three times. That is, a total of four key button inputs must be made.

On the other hand, in the present invention, when it is changed in the reverse direction, the cursor is positioned after the letter z and the modification key is input once to correct it to y.

Even if it is changed in the forward direction, since the modification key is pressed only three times, it can be seen that the number of key button inputs is significantly reduced as compared with the related art.

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, the present invention can improve the user's convenience because it is possible to modify the input character using only one modification key in a terminal equipped with a key input unit in which several characters are indicated on one key button. There is an effect that can significantly speed up.
