Description

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

The present invention relates to a character input method of a mobile communication terminal, and more particularly, to a character input method of a mobile communication terminal to minimize the number of button input when inputting Korean and other characters.

Recently, the mobile communication terminal is gradually developing into a portable information device by adding various additional functions to a simple telephone, and input functions such as SMS, phone number, schedule, memo, and other information are basically provided. Even chat and web surfing are possible.

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 research subject in order to easily input characters in order to increase user convenience.

Next, a method of using the additional function is outlined.

In general, most mobile communication terminals display a menu when a specific function key (menu button) of a keypad is pressed, as shown in FIG. 1, and when a user selects one desired function among the displayed menus, editing for character input is performed. It is supposed to switch to the screen.

Then, the user sees the Hangul or English alphabet written with the number on each button of the keypad and press the corresponding button to output the desired character to the screen.

In particular, in the case of Hangul, unlike English and other special characters, it is composed of a combination of initial, neutral, and final characters. Therefore, when one button is pressed, two or more characters are matched. Since the size of the button is small, even when three or more characters are matched, only typical consonants and vowels are displayed as shown in FIG. 2.

In other words, by using the above-described method, 10 buttons (<0> to <9>) on the keypad are used to express 2350 double-byte Korean standard code 2350 KSC 5601 and 11172 characters in combination.

Next, Table 1 shows the number of buttons to be pressed when entering each surname character using the keypad of the mobile communication terminal to edit the Hangul in the configuration as shown in FIG.

Last name Count Last name Count Last name Count Last name Count end Episode 2 phrase Episode 2 River 4 times Equal 5 times Kim 3rd time volume 5 times I 3rd time foil 4 times within 5 times side 7th Choi 5 times car 3rd time tablet 3rd time being 4 times sulfur 8th Hong 7th

Next, the Hangul character input method using the above-described keypad will be described with reference to the flowchart of FIG. 3.

Once a user presses a menu selection button to use an arbitrary additional function (S11), various additional functions according to the same are displayed on the screen.

Then, the user selects a desired function among them, presses the edit button of the corresponding function to switch to the edit mode (S12), and inputs a Hangul alphabet (S13).

Accordingly, the keypad of the keypad used for entering a phone number in the normal mode is switched to input characters. For example, when the keypad is configured as shown in Fig. 2, when the first <1> button is pressed, the '?? 'Is displayed, and then press once more to output' ?? '.

Therefore, when the user presses the first key, that is, enters the consonant (S14), the terminal checks whether the consonants (consonants and consonants) that can be entered as consonants are displayed, and if it is corrected, the terminal waits for the next key input. (S15).

Next, the user enters the neutral when the first star is displayed on the screen (S16), and at this time, the terminal checks whether it is a letter (vowel, double vowel) that can be entered as a neutral, if it is displayed on the screen, and inputs the next key. Wait for (S17).

Accordingly, when the character input is completed in neutral, the user ends the character input by pressing the 'done' button or the 'next' button without inputting the final character, or inputs all the final characters in the above manner. Terminate character input.

Of course, even at this time, when the finality is input (S18), the terminal checks whether it is a consonant (consonant, double consonant, double consonant) that can be input as the finality, and if it is displayed on the screen (S19) to complete the Hangul character combination ( S20), by repeating the above process to form a sentence.

By the way, in the case of inputting Korean characters by the conventional method, the maximum number of buttons pressed to input the desired alphabet according to the alphabet matched to the button is three times for vowels, four for vowels, three for consonants, The number of button consonants is 5 times, the double consonants is 4 times, and the number of key inputs is complicated. Also, the keypad layout is complicated. Because there is a problem that takes a lot of time to complete the character.

Therefore, the present invention was created to solve the above-mentioned conventional problems, and outputs a letter in the form of a matrix on the screen, which can be automatically entered as initial, neutral, and final according to the Hangul combination order, and each button of the keypad. The purpose of the present invention is to provide a character input method of a mobile communication terminal for minimizing the number of button inputs by moving the cursor to use a direction key indicating the front, back, left, right and diagonal directions.

6A and 6B are flowcharts illustrating a Hangul character input process of a mobile communication terminal according to the present invention.

According to an aspect of the present invention, a first step of displaying a letter that can be input in initial form according to a Hangul combination order on a screen when a terminal is switched to an edit mode; A second step of displaying, on a screen, a letter which can be automatically entered as a neutral when a user selects one of the displayed letters and inputs a consonant; A third step of displaying on the screen a letter which can be automatically entered as a final word when a user selects one of the displayed letters and inputs neutral; The user inputs one of the displayed letters to complete the character combination, or moves the character input position to complete the character combination with only the initial and neutral characters.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

First, the character input method according to the present invention does not sequentially press each button to match the letter of the conventional method until the desired letter is output, it can be input in the consonant, neutral, final according to the Hangul combination order The letter is automatically displayed on the screen, and the user moves the cursor using the mouse ball or the keypad as an arrow key and selects and inputs the desired letter from the letter arranged on the screen.

In this case, the cursor is always in the center of the array.

For example, if you have a three-row, three-column array, then the letters in the second, second, and second columns will be centered, so the cursor will be positioned at that location when the first screen is displayed. If it is less than or equal to, the letter in the second row and second column is centered on the upper left corner.

On the other hand, according to the present invention, the type of letters to be input (consonant, vowel, vowel consonant, double consonant, vowel consonant) according to the Hangul combination order, that is, initial, neutral, and final, is automatically displayed on the screen as shown in FIG. There is no need to find the letter written on the button.

At this time, the type of the Hangul alphabet can be classified into five types, as shown in the following Table 2.

Kinds Configuration Double consonants ㄲ ㄸ ㅃ ㅆ ㅉ Lucky consonants (11 characters) ㄳ ㄵ ㄶ ㄺ ㄻ ㄼ ㄽ ㄾ ㄿ ㅀ ㅄ Double Vowels (11 Characters) ㅐ ㅒ ㅔ ㅖ ㅘ ㅙ ㅚ ㅝ ㅞ ㅟ ㅢ Consonant (14 characters) ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅇ ㅋ ㅋ ㅋ ㅋ ㅋ Vowel (10 characters) ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ ㅠ ㅡ ㅣ

Here, the consonants and twin consonants can be inputted as consonants, and the vowels and double consonants are inputted as neutral consonants, and the consonants, double consonants and twin consonants inputted as final consonants.

Also, Hangul means' ga, me… ', Only the first and neutral are used, or' river, moon… '. Since the initial, neutral, and final characters are all used together, such as', the characters that do not need to enter the final characters are moved by pressing the 'next' button on the keypad. In the moved position, the first letter of the next letter is printed on the screen so that you can input it.

In this case, the 'next' button and the 'before' button may use different buttons depending on the type of the terminal, but generally use the <*> and <#> buttons.

Next, the character input process of the mobile communication terminal according to the present invention will be described in more detail with reference to the flowcharts of FIGS. 5 and 6.

FIG. 5 is an exemplary view for explaining the use of each button of the keypad as a direction key indicating the front, rear, left, right, diagonal directions.

For the sake of simplicity, the process of switching to the edit mode of the corresponding additional function by pressing the menu selection button is the same as the conventional method, and thus, the text input process will be described immediately in the edit mode.

First, when switching to the edit mode (S31), the screen displays all the consonants, as shown in Figure 4 (a) of the consonants that can be entered as a consonant in the Hangul combination order (S32).

Of course, the position of the cursor that is first displayed at this time is the letter (??) in 2 rows and 2 columns regardless of the number of the matrix as described above, and the number of the keypad button corresponding thereto becomes <5>.

The <5> button is a button located at the center of the keypad, which matches the center of the alphabet letter array displayed on the screen, that is, the letters in the second row and the second column. The button does not indicate a direction and selects the letter with the current cursor. It is a button to.

Therefore, if you enter '??' as the initial constellation, press the <5> button immediately. If you enter the letter (??) in the diagonal direction on the right side, press the <3> button pointing in the diagonal direction. Likewise, if you enter a letter (??), press <6>, <6>, <2> or <2>, <6>, <6> sequentially or <3>, <6 depending on the direction. Press>.

If the first consonant is input instead of the consonant (S33), pressing the 'Next' button to display the twin consonants as shown in Figure 4 (b) (S34).

Of course, in the above case, the cursor is positioned at the center letter (??), and the desired letter is input by pressing a button pointing to the corresponding direction (S35).

Next, when the initial consonant is outputted on the screen by the above process, the terminal first displays all the vowels as shown in FIG. (S36).

Of course, the cursor position is the center of the array, i.e. the letter in the second row and the second column, as in the process of entering the initial consonant, and the number of the keypad that matches it is also the center position <5>. do.

Therefore, if you enter '??' for neutral, you can press the <5> button immediately. If you want to enter the letter in the diagonal direction, press the <3> button for the diagonal direction. If you want to enter the lower alphabet, press <7>, <8> in order.

If the user inputs a vowel vowel rather than a vowel (S37), pressing the 'next' button causes the vowel to be displayed as shown in FIG. 4 (d) (S38).

At this time, the cursor is positioned at the center letter and the desired letter is input by pressing a button pointing to the direction (S39).

Next, when the initial and neutral are outputted on the screen by the above process, as shown in (a), (b), and (e) of FIG. The consonant array is selected and displayed (S41).

Of course, in this case, the desired consonant may be selected by using a direction key or a mouse ball in the consonant array in the same process as when the initial consonant is input, and in the case of a consonant consonant as shown in FIG. In the same manner, since the desired letter is selected (S44), description thereof will be omitted.

At this time, if you press the 'previous' button to modify the combination of letters during the combination of the letters (S46), the letter is currently combined is canceled, the letter is displayed on the screen in the reverse of the letter combination depending on the number of times the button is pressed It is erased and allows new input.

For example, pressing the 'previous' button during the final input cancels the final input screen, switches to the neutral input screen, and pressing the 'previous' button once again switches to the initial input screen.

That is, it is necessary to determine where the part to be corrected (S47) is selected and input a new letter at the corresponding position by the above-described process.

When the character combination is completed, press the end key to end editing.

In addition, as described above, the Korean characters are combined, and the letters are displayed on the screen to be selected. However, in the case of non-combined English and special characters, the input may be inconvenient. You can also set the methods individually.

As described above, the character input method of the mobile communication terminal of the present invention does not need to print the Hangul alphabet on the keypad of the terminal and has the effect of reducing the number of inputs of the desired alphabet to about 2 times to 4 times.

In addition, according to the present invention, the corresponding letter is automatically displayed on the screen in the form of a matrix according to the Hangul combination order, so that the user can select the desired letter by using the arrow keys or the mouse ball. It is effective.
