Description

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

The present invention relates to a character input method, and more particularly, to a character input method of a mobile communication terminal capable of quickly combining a minimum number of button inputs when entering Korean characters in a mobile communication terminal.

Recently, the mobile communication terminal is gradually developing into a portable information device by adding various additional functions in addition to a simple phone function, and is basically equipped with input functions such as SMS (Short Message Service), telephone number, schedule, memo and other information. 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, so that the character is input using a keypad attached to the terminal.

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

1 illustrates a number and a function key ('*', '#') used to input Korean characters in a conventional mobile communication terminal. The letter and function key ('*', '#') matched with a numeric key is shown. You can enter Korean by using).

Then, for example, the number of presses of the numeric keys and the function keys and the constitution of the letter corresponding to each keypad button may be illustrated in Table 1 below.

For example, if the user wants to enter shovel,

'7' + '3' + '5' + '*'-> shovel

'5' + '*' + '#' + '3'-> bar

You can input like this.

In addition, although not shown in Table 1, a compound consonant and a compound consonant can be combined combining the alphabet shown in Table 1. For example, in order to input 'ㅟ', a double vowel 'ㅟ' can be combined by pressing the number key '6' corresponding to 'TT' twice, followed by pressing the number key '9' once. In order to input the first, press the number key '4' corresponding to 'ㄹ' once, and then press the number key '1' corresponding to 'a' once, and the compound consonant 'ㄺ' may be combined.

However, in the character input method of the conventional mobile communication terminal as described above, since a character is input by using the stroke addition button (*) and the double consonant button (#), which are function keys, a number key is used to add a stroke or make a consonant. There was a troublesome problem of pressing (0 ~ 9) and pressing the function keys (*, #) again.

In addition, since pressing the numeric keys (0-9) and pressing the function keys (*, #) again, there is a problem in that the length of time required for inputting a character is increased due to widening of the active radius of the finger.

Therefore, in view of the above problems, the present invention eliminates the stroke-adding function and the consonant function of the function keys (*, #) of Hangul characters disposed on the keypad, and the numeric keys (0-9) and the function keys (*, #). By matching each key with consonants and vowels that correlate with shape or pronunciation characteristics, the user can eliminate the hassles of pressing the numeric keys and pressing the function keys again to add strokes and double consonants. It is an object of the present invention to provide a character input method of a mobile communication terminal that can be quickly combined with a minimum number of inputs.

1 is an exemplary view showing a keypad configuration of a conventional mobile communication terminal.

2 is an exemplary view showing a keypad configuration of a mobile communication terminal having a character arrangement structure according to the present invention.

Character input method of the mobile communication terminal of the present invention for achieving the above object is a mobile communication terminal configured to input the Hangul by pressing the letter matching the numeric key (0 ~ 9) and the function key (*. #) In the present invention, the consonants correlated with the shape or pronunciation characteristics, including the terminal sound and the double consonant on one side of the diagonal line connecting the numeric key '1' and the function key '#', are arranged to match the same button, and the other It is characterized in that the vowels having mutually correlated forms or pronunciation characteristics on one side can be inputted with characters by matching the same one button.

Referring to the accompanying drawings, a preferred embodiment of the character input method of the mobile communication terminal of the present invention having the above characteristics will be described in detail as follows.

First, the character input method according to the present invention eliminates the conventional stroke addition button (*) and the consonant button (#), and the numeric keys in the 12 buttons including the numeric keys (0-9) and the function keys (*, #) On the left side of the diagonal line connecting '1' and function key '#', the number key on the left side and the function key (*, #) match consonants of similar shape or pronunciation characteristics to one key, and the number on the right side Consonants of similar shape or pronunciation to a key match a key.

Consonants matched to the diagonal left key include a terminal sound and a double consonant.

That is, in the present invention, as shown in Figure 2, including the terminal sound and the consonant sound, etc. (a, ㄲ, ㅋ), (c, ㄸ, ㅌ), (g) , ㅆ), (ㅁ, ㅂ, ㅃ, ㅍ), (ㅈ, ㅉ, ㅊ), (ㅇ, ㅎ) for the numeric keys' 1 ',' 7 ',' 8 ',' 0 'and function keys' * (ㅏ, ㅑ), (ㅓ, ㅕ), (ㅗ, ㅛ), (ㅜ, ㅠ), (ㅡ, ㅣ), which are correlated vowels matching ',' # ' To match the numeric keys '2', '3', '5', '6', and '9', thereby reducing the number of presses of the button for inputting the desired alphabet.

Also, unrelated consonants (b, d) are matched to the numeric key '4'.

Of course, in the case of double consonants (ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ), it is necessary to press a button that matches each consonant.

For example, to input 'ㄳ', press the number key '1' corresponding to 'ㄱ' and then press the number key '8' corresponding to 'ㅅ'.

In addition, when entering a vowel, press the numeric key '2' once to print 'ㅏ' using the diagonal right number key, and print 'ㅑ' if it presses twice, and press the number key '3' once to ' 'ㅓ' and press twice to output 'ㅕ', press' 5 'once to print' ㅗ ', press twice to print' ㅛ ', press' 6' once to press' ㅜ 'output and press twice to output' ㅠ '.

Next, when inputting the vowel vowels (ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, 조합), the vowels are combined as in the case of inputting the consonant sound.

For example, 'ㅚ' is 'ㅗ' + 'ㅣ', 'ㅙ' is 'ㅗ' + 'ㅏ' + 'ㅣ', 'ㅟ' is 'TT' + 'ㅣ', 'ㅞ' Is composed of 'TT' + 'ㅓ' + 'ㅣ'.

Also, 'ㅢ' is configured by pressing 'ㅡ' and pressing 'ㅣ' after a predetermined time passes.

Then, for example, the number of pressing of the numeric keys and function keys shown in Figure 2 and the configuration of the letter to match each keypad button can be shown as Table 2 below.

For example, if the user wants to type 'cuddly',

Conventionally, '1' + '#' + '3' + '3' + '*'

In the present invention, '1' + '1' + '3' + '3'

You can input like this.

Also, to enter 'Sappa'

'8' + '2' + '*' + '*'-> shovel

'*' + '*' + '*' + '2'-> bar

In this way, the last '*' key for constructing the 'shovel' and the first '*' key for constructing the 'fast' must be entered after a preset time.

As described in detail above, the present invention eliminates the stroke-adding function and the consonant function of the function keys (*, #) of the Hangul characters arranged on the keypad, and the numeric keys (0-9) and the function keys (*, #). By matching each key with consonants and vowels that correlate with shape or pronunciation characteristics, you can eliminate the hassle of pressing the numeric keys and pressing the function key again to add strokes and double consonants. Minimize the number of times can be combined quickly.
