The present invention relates to a character input method of a mobile communication terminal, and more particularly, to a character input method of a terminal using a pattern for inputting a character according to a pattern of a character.

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 Code to the Hangul Completion 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.The first key is' ㄱ, ㄴ ', the second key is' ㄷ, ㄹ, ㅋ', the third key is' ㅁ, ㅂ, ㅌ ', and the fourth key is' ㅅ, ㅇ ',', 'Key', 'key', 'key', key '6', 'key', 'key', key '7', key, 'key', key, '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.

In addition, the keys 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 have consonants and vowels assigned to one key each of three consonants and corresponding phonemes according to the number of times of pressing a specific key. As the input is changed, the user finds and inputs the required phonemes.

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

"Yes" is completed by continuous input of number keys 4, 4, 0, 0 and #.

"" Is completed by continuous input of number keys 2, 2, 8, 2, 2 and #.

"S" is completed by successive input of numeric keys 2 and 8 and 2, 2 and #.

"Side" is completed by successive input of numeric keys 3, 7, and 7, and 7, and 1, 1 and #.

3 is a conceptual diagram illustrating the input mapping group in FIG. 2, in which a phoneme (Korean or English input) that a user wants to input is set as a group 10 and a corresponding group is referred to as an input mapping group. In order to select a phoneme of the desired group 10 as a group (20), a mapping corresponding to the phoneme is selected only by pressing a numeric key corresponding to the input mapping group 20 so that the phoneme is displayed on the display screen. do. In other words, if you want to input 'b', select '1' of the input mapping group 20, and if you want to select 'A', press 2 + 2 + 2 + 2.

However, as in the diagram of FIG. 2, since almost three keys are assigned to almost every letter, it is difficult for the user to remember the keyboard, and the characters are processed by counting the repeated number of specific numbers. The type of input that can input specific characters is limited.

Therefore, in the input method where the number of buttons like the current terminal is limited, the consonants are distinguished according to the number of presses of a specific keyboard. If the user is not familiar with the position of the keyboard, the keyboard should be reported at all times. There is a problem that you cannot input.

The present invention has been made to solve the above-mentioned conventional problems, and the user can add a predefined basic input group and a user-defined pattern that matches the character pattern so that the user can search and input a character matching the pattern pressed. It is an object of the present invention to provide a character input method of a terminal using a character pattern to display matching patterns and select a matching pattern after comparison through one additional user group.

Character input method of the terminal using a character pattern according to the present invention for achieving the above object,

Comparing whether the pattern matching the desired group with respect to the pattern for which the user wants to input a specific character corresponds to the input matching group;

Displaying patterns when there is a matching pattern as a result of the comparison;

And searching for a matching pattern among the displayed character patterns, and selecting a pattern if there is a matching pattern.

In detail, the input matching group includes a basic input group storing patterns matched with different patterns of each character, and a user adding group storing arbitrary character patterns according to a user input method. .

In detail, the user adding group stores a group added by the user when there is no matching pattern, and a group matching a letter or a character string.

In detail, if there is no pattern matching the character pattern input by the user, the user may define and add the input pattern item.

Referring to the accompanying drawings, a character input method of a terminal using a character pattern according to an embodiment of the present invention configured as described above is as follows.

FIG. 4 is a diagram illustrating matching between a desired input group and an input method group according to an embodiment of the present invention, FIG. 5 is a diagram showing an example of character input using a character pattern according to an embodiment of the present invention, and FIG. A flowchart illustrating a character input method using a pattern in a terminal according to an embodiment of the present invention.

Referring to FIGS. 4 and 5, a desired letter (a Korean letter / vowel, an alphabet) is used for a 3 × 4 key assigned to a key matrix of a mobile communication terminal by using a plurality of key groups in the shape of the letter. It is possible to express, and can use the patterns to express Hangul alphabet and alphabet.

The input matching group group 200 uses the basic input group 201 and 211 and the additional group of users 202 and 212 for various patterns as the shapes of the characters of the group 100 who wants to input such patterns. Can be entered.

If the desired group 100 is "a", the input matching group 200 matched thereto is numeric keys 1 + 2 + 4, numeric keys 1 + 2 + 5 (+8 (+0)), numeric keys 1+ 2 + 3 + 6 (+9) and the like and other patterns as the basic pattern of the phoneme,

If the desired group 100 is "ㄷ", the input matching group 200 is numeric keys 2 + 1 + 4 + 5, numeric keys 3 + 2 + 5 + 8 + 9, numeric keys 6 + 5 + 8 + 0 + # Patterns other than and other patterns as the basic pattern of the phoneme,

If the desired group 100 is "A", the input matching group 200 has a pattern of numeric keys 2 + 4 + 7 + 6 + 9 and numeric keys 5 + 2 + 4 + 7 + * + 6 + 9 + # + 8. And other patterns as the basic pattern of the alphabet,

If the desired group 100 is "a", the input matching group 200 is numeric keys 2 + 1 + 4 + 7 + 8 + 5 + 9, numeric keys 5 + 2 + 1 + 4 + 7 + * + 0 + 8 You can input the + # pattern and other patterns as the basic pattern of the alphabet.

In this way, basic patterns such as other Korean characters, alphabets, and special characters can be set.

Each of the basic patterns may be defined as a plurality of patterns for one letter or alphabet of the desired input group 100, and is defined as an input matching group 200 for distinguishing them.

 The input matching group 200 may be composed of basic input groups 201 and 211 and additional user groups 202 and 212. The basic input groups 201 and 211 set basic patterns of phonemes.

That is, the basic input groups 201 and 211 correspond to one-to-one matching patterns (a, a + a, b, b +) for any pattern of the desired input group 100 to be input by the user. b, c, c + c) and define one-to-one matching on the 'a' pattern.

In addition, when the user tries to express a specific phoneme by pressing a random pattern, the user adder group 202, 212 provides the user with a match item (phoneme) for the pattern when the phoneme is not set in the basic input group 201,211. If you choose, add the pattern for the phoneme to the additional group if you choose.                     

 When the user selects the desired input group 100 for the character pattern in the key matrix of the terminal, it is compared whether the corresponding pattern matches the phoneme in the basic input group 201, and if the basic input group 201, 211 exists. If it does not match, it can be represented, and if it does not match, the search is performed in the additional group 202, 212, and if not, the user can add the phoneme pattern.

In addition, in view of an extension of the matching of the phonemes, the input matching group 200 may define specific letter patterns or specific word patterns corresponding to specific characters.

That is, it can be defined one-to-one as one macro or another macro that groups each pattern of ㅎ + ㅗ + ㅏ + ㄹ called "bow", so that a specific character or a specific string may be defined in the user addition group 212. Can be.

6 is a flowchart of a character input method using a phoneme pattern of a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 6, if the current counter for the currently input key signal is stored in the basic input means 201 and 211 and the user addition group 202 and 212 when the counter is not exceeded and the time set in the counter is not exceeded. (S101, S102). If there is a match pattern, the match patterns are displayed on the screen (S103). If a match pattern is selected, the selected pattern is stored (S106) and the pattern is reset (S105).

Here, if there are no current patterns in the basic input groups 201 and 211 and the user additional groups 202 and 212, when the user selects a match item for the current pattern, the patterns are stored in the user additional groups 202 and 212.

If the counter does not exceed the set time (S101), if the key input signal is not the end signal (S107, S108), the counter is reset and it is searched whether the current pattern is in the basic pattern or the pattern stored by the user ( S110). If there is a current pattern, the matching patterns are displayed on the screen (S111), and the counter is restarted (S101).

Here, the setting time of the counter may be divided by the Hangul alphabet or the addition of a macro function, and according to the distinguishing function, the user may input a character pattern while using the set time.

In addition, since Hangul is composed of a combination of consonants and vowels, consonants and vowel inputs can be distinguished according to the current state, and can also be moved to the next syllable using another specific key.

In addition, since the input method is different for each user according to a specific character, it is recommended that there is a part that is similar or not similar to the pattern that is input from the user. If there is no similar pattern, it selects from the whole character or inputs to map to the desired string. In addition, the next syllable can identify the current state with a specific key (such as a side key).

In addition, although the user has described the general button in the present invention, it is also within the scope of the present invention that the character may be input according to the above-described character pattern in the touch button.

According to the Hangul input method of the present invention as described above, the character input method of the mobile communication terminal using the character pattern, while the user learns a group and additional groups that have the shape of the character and the character string and one-to-one matching the shape By making it selectable, if characters can be input without memorizing a keyboard separately, there is an effect that can be learned more easily and can be used conveniently.
