Description

Editing method of character for cellular phone}

The present invention relates to a method of inputting a character of a mobile phone terminal, and more particularly, to display a character input on a liquid crystal display, and input a character specified in advance on a keypad in order to create a desired sentence of a mobile phone It is about a method.

The mobile communication system sends a call message containing the unique number of the mobile terminal called through the call channel of the base station to call the mobile terminal, and when a response comes from the specified mobile terminal, a call is established between the sender and the receiver. It is a system that makes it possible.

In addition, such a mobile phone terminal has been able to communicate data as the digital method is adopted, it is possible to provide a variety of services such as text services by using such data communication.

In order to input characters required for such data communication, the mobile phone terminal is provided with characters that are assigned to each keypad in addition to numbers to keypads for inputting numbers, as in conventional telephones. Special characters, etc., the user can express almost anything you want.

The present invention relates to a text input method of a mobile phone that allows a user to use a mobile phone more conveniently by inputting a text or the like in the mobile phone terminal as described above.

A conventional character input method will be described with an example using the keypad shown in FIG. 1.

In order to input an alphabetic character, the keypad includes two to three corresponding buttons of the respective numeric buttons and the corresponding English alphabet.

That is, QZ is set to 1, ABC is set to 3, DEF is set to 4, GHI is set to 5, JKL is set to 6, MNO is set to 6, PRS is set to 7, TUV is set to 8, and WXY is set to 9.

In the conventional character input method using a keypad in which English letters are written together, numbers are inputted by dialing the buttons in which the corresponding numbers are written in the same way as the number input button of a telephone when a number is first input. .

In case of entering letters, the function assigned to the button is displayed by pressing the same number button several times in succession after switching from call mode to letter input mode by operating a separate function button. Depending on whether you have operated the number of times, the English characters written on the corresponding button are sequentially changed and input.

For example, pressing the number button [3] once will display the first letter, D, on the LCD display, pressing [3] two times in succession, E three times in succession, and F will appear. When pressed consecutively, 3 is displayed.

That is, if you keep pressing [3], D, E, F, 3, D, E…. Appears sequentially on the liquid crystal display, and if desired characters appear, allow a certain time to elapse, allowing the current character to be input to the mobile phone terminal, and moving the cursor on the liquid crystal display to receive the next character. Using the same method as before, you can continue typing to produce sentences.

However, in the conventional method of inputting a character, in order for a desired character to be input, the user presses each number button to sequentially search for a number entered in one button to find a desired character. Wait as much as possible.

Therefore, this method must not only remember exactly how many times the user has pressed a number, but also wait to check and display the displayed characters when the desired characters appear on the LCD display, and to enter characters different from those desired during this process. There is a problem that the input is often a sentence that is different from the sentence that the receiver wants.

In view of the above problems, the present invention, in the case of inputting a desired character from a plurality of characters allocated in parallel to one button, by pressing the button only once without multiple button operations, it is possible to enter characters more easily and simply It aims to provide a way to prevent typographical errors.

In order to achieve the above object, a text input method of a mobile phone according to the present invention comprises: a text input mode selection step of selecting a text input mode to input a text corresponding to a sentence desired by a user; Pressing a button to find a button in which a desired character is written in the character input mode and pressing a button; A character scroll step of causing the characters written in the corresponding button pressed in the button pressing step to be sequentially scrolled and displayed at regular intervals; And a button press releasing step of releasing the pressed state of the button to fix the desired character when the user finds a desired character in the character scrolling step.

That is, according to the present invention, if a button is kept pressed, a character is automatically displayed after a predetermined time has elapsed, so that another character written in the button can be inputted, thereby allowing the user to enter a character more conveniently.

However, in the description of the character input method, previously known parts will be omitted.

The character input method according to the present invention will be described with reference to the arrangement of the keyboard as shown in FIG. 1. FIGS. 2A to 2C are sequentially applied to express the English word “boy” by applying the method according to the present invention. It is a figure explaining that an input method is used.

Referring to FIG. 2A, a user first changes a work mode to a mode in which a user can input a text, and then enters a letter “b” written in a numeric button “2” on the keypad 2. To do this, press the "2" button in English input mode.

Thus, the letter "a" corresponding to the first display of the number button "2" is displayed on the liquid crystal display 1, but conventionally, in order to input another letter written in the button, the button is removed. Afterwards, the button had to be pressed again, but in the present invention, if the button is kept pressed, the display automatically goes to the next letter of the button, and when the button is removed, the corresponding letter is input.

Therefore, in order to finally input the letter "b", it is necessary to keep pressing the number button "2", and then automatically move to "b" which is the next letter of the letter "a", and the liquid crystal display 1 displays "b". b " is displayed and after the letter " b " is displayed, the pressing state of the " 2 " button is restored to the original state so that " b &quot; is fixed to the liquid crystal display 1;

After "b" is displayed on the liquid crystal display 1, the cursor moves to the next and waits for the input of the next character. Since the current state is not pressed, the user waits for the input. The number button "6", which is a button for inputting a button, is pressed, which is shown in FIG. 2B.

However, even in this state, since "m" appears as the first letter on the numeric button "6", the "b" entered earlier and the "m" entered next are added to the liquid crystal display 1 so that "bm" appears. When the number button "6" is kept pressed in this state, the next character "bn" written together with the number button "6" is displayed, and then "bo", which is a desired character, is displayed on the liquid crystal display. In this case, when the number button "6" is removed, "bo" is fixed and appears on the liquid crystal display 1.

However, if the button is kept pressed even after "bo" is displayed, other preset characters such as 6 of "b6" are displayed, and eventually the display returns to the initial input state and "m" is inputted to display the liquid crystal display. "Bm" is displayed in (1).

As such, if another special character or number is written next to the letter “o” in this input mode, “m” is not displayed on the liquid crystal display 1, but other special characters or numbers may be displayed. will be.

In this way, even if a button contains English as well as other characters on the button, at the end of the staging character, the character is returned to the first character displayed so that the user may accidentally modify the character entered. do.

In addition, referring to FIG. 2C, this means that in the same manner as the salping in FIG. 2A and FIG. 2B, the number button "9" in which the letter "y" is written is kept pressed, so that "bow", " After the box "," boy "is displayed sequentially, the user can complete the character" boy "by releasing the pressing state of the number button" 9 ".

After the user inputs the desired character correctly, the user can save or enter a phone number that matches the input character so that the user can continue the desired operation.

As described above, the method may be used to input several characters longer, so the user may write a longer sentence if desired.

However, the characters written in the numeric buttons can be inputted in advance in various modes, if necessary, by changing the mode from time to time. May be different as desired by the user.

In addition, the same method can be applied to the Hangul character input method of the mobile phone terminal as described above, Figures 3a to 3c is an illustration illustrating this.

Referring to FIG. 3A, if the user wants to input the character "half", the user must input "ㅂ", "ㅏ", and "b" in sequence by using the keypad (see FIG. 1). After changing the input mode to Korean input mode, press the number button "3" with the letter "ㅂ" written in parallel.

When the numeric button "3" is pressed, "ㅁ", which is written first in sequence among the characters stored sequentially, is first displayed on the liquid crystal display 1, but if the numeric button "3" is kept pressed, the "ㅁ" Next, the display is displayed on the liquid crystal display 1 when the display is moved to the stage of "ㅂ", and when the release state is immediately released, the character "1" is fixedly displayed on the liquid crystal display 1.

After the character "ㅂ" is entered using the number button "3", the user enters the number button "6" with the letter "ㅏ" to enter "ㅏ" without any number button being pressed. Is pressed, and the character "bar" is automatically displayed on the liquid crystal display 1, at which time the user releases the pressing state of the number button "6" to the "bar" displayed on the liquid crystal display 1; To be fixed, as shown in FIG. 3B.

Figure 3c is a view showing that the last support "b" of the "half" character wanted to enter in the first place, the user enters the "b" character after the "bar" is not pressed any button "b" character Press the number button "1" on the side of the screen and release it. Then "half" is entered and fixed.

In this case, since the input of the button displaying all the characters is terminated, the user can continue the desired work by inputting or storing a telephone number corresponding to the input characters.

As described above, the present invention is a method of inputting a character, without having to press a button several times in order to input a desired character from a button having several characters written together, one button is automatically pressed continuously. Since the characters written in SCR are displayed scrolling sequentially, the user can more conveniently create the desired character or sentence.

In addition, according to the type of characters to be input, the user inputs the sentence in different forms, such as English, Korean, and special characters, so that various types of sentences can be realized. The time replaced by another character can be adjusted to the desired level according to the user's age or position.

On the other hand, in the specific idea of the present invention, if the button is continuously pressed, the letters are automatically scrolled at regular intervals so that the letters corresponding to one button are sequentially displayed on the liquid crystal display. By completing the sentence by releasing the corresponding character by releasing the corresponding character, it is irrelevant to the type of the character previously inputted to each button or the method of forming such a character, and in addition to the methods already known. The present invention may be used more effectively by applying an input method.

Character input method of the mobile phone terminal according to the present invention, after selecting a specific mode in the text input mode of English or Korean previously inputted to the respective buttons to help the user to conveniently find and input the desired character, By preventing a mistake that may occur during the input process of the button, the user can use the mobile phone more conveniently.
