Abstract

PURPOSE: A character inputting method of a mobile communication terminal is provided to easily and quickly input a character by adding a shift function key. CONSTITUTION: If a terminal is in a character input mode(S11), it is first judged whether a shift key has been depressed(S12) to determine how many letters assigned for a button to be next depressed should be passed by. If a first shift key is depressed(S13), the second letter assigned to the button is selected(S14). If the first shift key has not been depressed, it means that a second shift key has been depressed, so a third assigned letter is selected(S15). If the shift key is not depressed but a character button is directly depressed, the number of how many times the character button has been depressed is counted(S16) and a letter corresponding to the number of times is inputted(S17). If there is no shift-only key, when a current mode is changed to the character input mode, a corresponding key is switched to a shift key(S18).

Description

Character input method of mobile communication terminal {CHARACTER INPUT METHOD FOR MOBILE COMMUNICATION DEVICE}

The present invention relates to a character input method of a mobile communication terminal. Particularly, in case of pressing a button to which a plurality of characters are assigned together with the shift key by adding a shift function key to the terminal, one or two digits of the allocated characters are provided. The present invention relates to a text input method of a mobile communication terminal that enables text input at a skipped position so that text can be input quickly and easily.

In recent years, mobile communication terminals have been gradually developed into portable information devices by adding various additional functions to simple telephone functions, and input functions such as SMS (Short Message Service), telephone number, schedule, memo and other information are basically provided. Not only that, but now it is possible to chat and surf the web.

However, most of the additional functions are performed by inputting a character, and are configured to input a character by using a keypad attached to the terminal.

Therefore, in addition to improving the call quality, the terminal manufacturer has also become an important field for improving the user's convenience by easily inputting characters.

In general, each button on the keypad is matched with three or more characters in Korean and English, and each time the button is pressed, the characters matched with the button are cyclically outputted.

However, in the case of inputting a character by the conventional method, when inputting the character assigned to the last (for example, the third allocated character) in each button, the desired character must be pressed three times in succession. Because it can be, there is a problem that takes a lot of time to complete the sentence.

Accordingly, the present invention has been made to solve the above-mentioned problems. When a button having a plurality of characters assigned to the terminal is pressed with a shift function key added to the terminal, one digit of the allocated characters is used. Another object of the present invention is to provide a character input method of a mobile communication terminal that enables a character to be input quickly and easily by inputting a character at a position skipped by two digits.

The present invention for achieving the above object, the first mode of the terminal, if the character input mode, the first step of determining whether the character input button is pressed first or the shift key is pressed first; A second step of determining, when the shift key is pressed first, a number of skips among the letters allocated to the letter input button to be pressed subsequently; A third step of, after skipping the determined number of characters assigned to the pressed character input button while the shift key is pressed, outputting the next sequence of characters; When the character input button is first pressed in the first step, the number of times of pressing is counted, and among the letters assigned to the character input button, a fourth step of outputting a sequence of characters corresponding to the count may be performed.

1 is an exemplary view illustrating a character input method of a terminal in which a plurality of characters are assigned to each button of a keypad according to the present invention.

2 is a flowchart illustrating a character input method using a shift key according to the present invention.

The present invention has one or more shift function keys to be used for character input, and depending on which shift key is pressed, the character at one or two shifted positions among the characters assigned to the button is directly input. There is a characteristic.

If the button is pressed without pressing the shift key, the same button may be continuously pressed in the order in which the characters are assigned, as in the conventional character input method.

That is, the shift key of the present invention is effective only while pressing like a keyboard of a computer, but when two or more shift keys are provided, for example, when the corresponding button is pressed while the first shift key is pressed, the button is pressed. If a letter shifted from one of the assigned letters is selected, and the corresponding button is pressed while holding the second shift key, the letter shifted from the letter assigned to the button is selected.

In this case, the shift key may be provided with a dedicated key in the terminal body, but when a character is input, a specific button may be converted into a shift key in software.

Although it depends on the type of the terminal, as shown in FIG. 1, two volume control keys are added to the side of the terminal as side keys, and it may be appropriate to use the volume control key as a shift function key.

For example, when three letters 'A', 'B', and 'C' are assigned to button 2 of the terminal, in order to continuously input 'ABC' in a conventional manner without a shift key, You have to press 6 key 2 times with '2 key + (2 key + 2 key) + (2 key + 2 key + 2 key)'.

However, in order to input 'ABC' according to the present invention, it is necessary to press a total of 2 times with '2 key + (Shift_1 + 2 key) + (Shift_2 + 2 key)'.

In other words, to input 'A', only press No.2, and to enter 'B' and 'C', press the second key simultaneously while pressing the first shift key (Shift_1) and the second shift key (Shift_2), respectively. .

2 is a flowchart illustrating a character input method using a shift key according to an embodiment of the present invention. As shown in FIG. 2, a key is distinguished from a case in which a shift key is pressed and a case in which the shift key is not pressed. Characters are cycled by the number of times they are pressed, and when a shift key is pressed, one or two digits are skipped to be entered.

That is, when the current mode of the terminal is the character input mode (S11), it is first determined whether the shift key is pressed (S12), and the number of skips among the letters allocated to the next pressed button is determined.

That is, when the first shift key is pressed (S13), the second allocated character is selected by skipping one of the letters assigned to the next pressed button (S14), and if the shift key is not the first shift key, Since the second shift key is pressed, the second shift character is selected so that the third assigned character is selected (S15).

If the character button is pressed immediately without pressing the shift key, the number of times of pressing is counted (S16) and the sequence of characters corresponding to the number of times is input (S17).

If there is no shift dedicated key, that is, if a dedicated key is assigned to a shift key among existing keys, the method further includes converting the corresponding key into a shift key when the current mode is switched to the character input mode (S18). ).

Accordingly, the user can input characters by pressing only the character button or by inputting characters by a combination with a shift key or by entering a character in a manner convenient for the user.

As described above, the character input method of the mobile communication terminal according to the present invention adds a shift function key to the terminal and presses a button assigned with a plurality of characters together with the shift key. By inputting the characters in the skipped position, there is an effect that can be entered quickly and easily.
