Description

Hangul input method of mobile communication terminal {Method for inputing Hangul in a mobile station}

The present invention relates to a Hangul input method of a mobile communication terminal, and more particularly to a Hangul input method of a mobile communication terminal that can improve the efficiency of Hangul input by separately setting a consonant-only, vowel-only conversion key and a pair of consonants. will be.

Hangul is based on the unification of Korean spelling, the initial consonants a, b, c, d, d, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k ㅉ, neutral ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅚ, ㅟ, ㅓ, ㅘ, ㅝ, ㅙ, ㅞ, finality a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ,, ,, ㅋ, ㅌ, ,, ㅎ, ㄲ, ㅉ, ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅯ, ㅄ have.

The theoretical number of letters that can be formed by combining initial, neutral, and final is 11,172 (19 × 21 × 28) characters. However, the actual number of characters commonly used is about 2,500 characters, and in the case of commonly used completed codes or combined codes, 1800 to 1900 characters can be expressed in Korean. The existing code system assigns ㄲ, ㄸ, ㅃ, ㅆ, ㅉ and ㅑ, ㅕ, ㅛ, ㅠ, ㅒ, ㅖ, ㅔ, ㅐ when inputting from the keyboard.

In order to display the Hangul as a complete Hangul using the keys of the terminal, about 12 numeric keys (1,2,3,4,5,6,7,8,9,0, *, # provided in the terminal) ) To input corresponding to each vowel and consonant.

Recently, liquid crystal displays (LCDs) of mobile communication terminals are installed in many sizes in the main body, and data services such as the Internet, short message service, and mail are available, so that not only Korean display but also Korean input can be provided. It also becomes more important.

The Hangul input device of such a general terminal, as shown in Figure 1, the central processor (1) for controlling the system of the personal mobile communication terminal; A key input unit (2) connected to the central processor (1) and composed of a plurality of keys such as a screen change key, a numeric key, and an input completion key to allow a user to input a key value; A liquid crystal display (3) connected to the central processor (1) and the key input unit (2) to display a result processed by the central processor (1) and to display a key value input from the key input unit (2). )Wow; The memory 4 is connected to the central processor 1 and contains a Korean font.

In the general personal mobile communication terminal configured as described above, when a user inputs a number or Korean through the key input unit 2, the central processor 1 processes the input key value, and the input number is displayed on the screen 3 as it is. The inputted Hangul is searched for the key value input using the Hangul font built into the Hangul font memory (4), and converted from the Hangul Combination type code to the Hangul Completion type code according to the Hangul input internal automata by the Hangul input key. Display on the device (3).

2 is a diagram illustrating a key matrix as a first embodiment for showing a Korean input method of a conventional mobile communication terminal.

First, look at the phonemes assigned to each of the numeric keys: 'ㄱ, ㄴ' for the 1st key, 'ㄷ, ㄹ, ㅋ' for the 2nd key, 'ㅁ, ㅂ, ㅌ' for the 3rd key, and 'ㅅ, ㅇ for the 4th key. ',', 'Key', 'key', 'key', key '6', 'key', 'key', key '7', key '8, key' There is a structure in which 'ㅣ, ㅖ', etc. are arranged in 'TT, ㅠ, ㅒ' 0 key, and * key supports Korean English conversion and English capitalization, and # key is input between character strings.

The keys 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 are assigned consonants and vowels to one key each, corresponding to the number of presses of a specific key. Is changed and input, the user will find the required phonemes (字 素) to enter.

If you use these keys to complete the Hangul "for example" in a row, you need the following keystrokes:

Example: [4 [[4] [0] [0] [#]

To: [2] [2] [8] [2] [2] [#]

S: [2] [8] [2] [2] [#]

Pages: [3] [7] [7] [7] [1] [1] [#]

The completed string "for example" would require a total of 23 keystrokes.

However, as shown in the diagram of FIG. 2, since almost three keys are assigned to almost every letter, it is difficult for a user to remember the keyboard, and the number of times that a user must press a key when typing the phoneme naturally increases. As a result, the input time is long.

3 is a view showing a second embodiment of a Korean input method of a conventional mobile communication terminal, showing a key matrix of a terminal.

First, look at the phonemes assigned to the numeric keys in the key matrix. ','#'On the 3rd key,' ㄱ, ㅋ 'on the 4th key,' b, ㄹ 'on the 5th key,' ㄷ, ㅌ 'on the 6th key,' ㅂ, ㅍ 'on the 7th key,' ㅅ 'on the 8th key , ㅎ ', and' 9 'key,' ㅈ, ㅁ '' 0 ',' ㅁ ', etc. are arranged. * Key supports Korean English conversion and English capitalization, and # key is entered between letters.

Here, the vowels are combined using 'ㅣ', '·', 'ㅡ' arranged on the 1, 2, and 3 keys. That is, the combination of 'ㅏ' and '·' into a continuous input of 'ㅏ' and the combination of 'ㅣ' and '·' and '·' into a 'ㅑ' and the '·' And 'ㅣ' as a continuous input of 'ㅓ', the input input of '·', '·' and 'ㅣ' as a combination of 'ㅕ', the '·' and '-' Combination into 'ㅗ' as the normal input, Combination into 'ㅛ' as the continuous input of '·', '·' and 'ㅡ', 'TT' as the continuous input of 'ㅡ' and '·' Are combined, and '?' And '·' and '·' are continuously combined as 'ㅠ'.

When the string "for example" is completed using the numeric keys of FIG. 2, the following key input is required.

Example: [0] [2] [2] [1] [1]

: [5] [5] [3] [5] [5]

S: [6] [3] [5] [5]

Face: [0] [0] [2] [2] [1] [5]

The completed string "for example" would require a total of 20 keystrokes.

However, the Korean input method described with reference to the example of FIG. 2 has a simple vowel input method, which is good to be remembered. However, since the vowel must be repeated several times, selected, and combined, the user has to press more keys. . In addition, even a user who uses frequently has a problem that it is difficult to shorten the input time.

Therefore, in the related art, the scientific system of the initial, neutral, and final characters of Hangul is adapted to the English system to express the desired letter only by repeatedly pressing and selecting keys that the user does not recognize, and which do not greatly improve the characteristics of the initial, neutral, and final characters. Could.

In addition, the user is inconvenient to use, there is a problem that can not be easily learned.

The present invention has been made to solve the above-described problems, and provides a Hangul input method of a mobile communication terminal that can increase the efficiency of Hangul input by separately setting a consonant-only, vowel-only conversion key and a pair of consonants. Has its purpose.
