The number 0 key 110 is added to the English input mode in the Hangul input mode.

2 is a schematic block diagram showing a configuration in which text input is performed using the keypad 100 according to a preferred embodiment of the present invention. Referring to FIG. 2, when a corresponding key is selected and pressed by a user in the keypad unit 22 including the keypad 100 and an input signal is generated, the input signal is transmitted to the controller 21 and the controller 21. Interacts with the memory unit 23 to display a character on the display unit 24 corresponding to the input signal generated by the corresponding key. Here, the memory unit 23 may be, for example, a memory chip embedded in a mobile phone, and the display unit 24 may be a display window provided in the mobile phone. The memory unit 23 further stores various characters such as symbols, as well as consonants and vowels related to the Hangul characters to be assigned to the keypad unit 22, and stores the characters of the specific key generated by the keypad unit 22. According to the input signal, the controller 21 refers to the memory unit 23 and displays characters on the display unit 24 according to the input signal.

According to the keypad 100 according to the present invention, Hangul input is performed using only nine keys of the first to nineth numeric keys 111 to 119. When the user needs to write a short message or an e-mail, for example, by pressing the "Menu" key 11 to switch from the call mode to the Hangul input mode, the user inputs consonants and vowels alternately by combining letters and vowels while looking at each numeric key. Write the text you want.

First, in inputting Korean consonants, the numeric keys 111, 113, 114, 116, 117 to 119 to which consonants are assigned are assigned two consonants having similar pronunciations, that is, consonants accompanied by hard consonants (that is, In the case of double consonants), the number (111, 114, 117 to 119) numbers 1, 4, 7, and 9 are used to display the sound (ie, double consonants) "ㄲ, ㄸ, ㅆ, ㅃ, ㅉ" Each of these is allocated further. Therefore, the consonants assigned to the numeric keys can be displayed independently, for example, by the number of presses or the difference in the pressing time, depending on the operation method of the numeric keys.

That is, if any one of the numeric keys 111, 113, 114, 116, 117 to 119 to which the consonants have been assigned is pressed once, the first consonant among the consonant groups assigned to each of the keys, that is, a, b, c, o, s , ㅂ, ㅈ ”is input, and when pressed twice in succession, any one of the second consonants among the consonant groups assigned to each of the keys, that is, ㅋ, ㄹ, ㅌ, ㅎ, ㅁ, ㅁ, ㅁ It is configured to be. In addition, when inputting a hard sound (double consonant), when one of the numeric keys 111, 114, 117 to 119 to which the hard sound (double consonant) is assigned is pressed, the third consonant among the consonant groups assigned to these keys, i.e. It is comprised so that any one of "k, k, k, k, k" is input.

The input form of the consonants is summarized in the following Table 2. In the column of the numeric key operation method of Table 2, only one number is displayed, which means that the corresponding number key is pressed once. ("11") means to press the number key twice in succession, and bold type (for example " 1 ") means to press and hold the number key.

Secondly, in the input of a vowel, the keypad 100 according to the present invention has only a vowel of "-" and "ㅣ" in the number 2 key 112 and the number 5 key 115 for input of the vowel. It is assigned and configured to represent all vowels using only these two vowels. In detail, the "-" collection assigned to the number 2 key 112 may be used as the "-" collection by itself or as a horizontal stroke of a vowel, and the "#" assigned to the number 5 key 115 may be used. The collection itself is configured to be used as a collection or as a vertical stroke of a vowel.

Therefore, when the user inputs a Korean vowel, the user only needs to input the horizontal and vertical strokes in order according to the vowel stroke order. Therefore, only two numeric keys are assigned to the vowel, thus simplifying the configuration of the keypad and inputting the actual vowel. The simplicity of input at is improved, and the user can easily understand the Hangul input method.

For example, when the vowel "ㅏ" is input, the first time the numeric key 115 is pressed, the vertical stroke of the vowel "ㅏ" is input, and when the digit "112" is pressed continuously, the horizontal stroke of the vowel "ㅏ" is input. It is configured to be input. Similarly, in the case of the vowel "ㅓ", when the number 2 key 112 is pressed first and the number key 115 continues, the Hangul of the vowel "ㅓ" is comprised so that it may be completed.

In addition, since horizontal or vertical strokes in a vowel consist of short and long strokes, as described above with regard to consonants, press the keys 112 and 115 to which the vowel has been assigned once, twice in succession, or long strokes. By pressing, it is configured to distinguish between short and long horizontal lines or short and long vertical strokes. Therefore, the user uses only two numeric keys to input Korean vowels and feels convenient. In addition, the user inputs the horizontal and vertical strokes alternately according to the vowel order of the vowels. The hassle of selecting one of them can be avoided.

In more detail, the input of the Hangul vowel is described in detail. When the number 5 key 115 where the vertical stroke is input is pressed once, a short vertical stroke (for example, "ㅗ, TT, ㅚ, ㅟ, ㅘ, ㅙ, ㅝ, ㅞ" Vertical stroke) or a long vertical stroke (e.g., a long vertical stroke of "ㅏ, ㅓ, |, ㅐ, ㅔ, ㅚ, ㅟ, ㅑ, ㅕ, ㅒ, ㅖ, ㅝ, ㅙ, ㅝ, ㅞ, ㅢ) is input. Here, in the latter case, a long horizontal stroke may be input by pressing the fifth numeric key 115 once when the consonant is input immediately after pressing the fifth numeric key 115. In addition, when the number five key 115 is pressed twice in succession, a vowel in which two vertical strokes of a double vowel are entered, for example, two vertical strokes of "ㅛ, ㅠ" can be input at a time.

On the other hand, pressing the number 2 key 112, the horizontal stroke is input once (for example, "ㅏ, ㅓ, ㅏ, ㅔ, ㅚ, ㅟ, ㅑ, ㅕ, ㅒ, ㅖ, ㅘ, ㅙ, ㅝ, ㅞ) Or a long horizontal stroke (e.g., a long horizontal stroke of "ㅗ, ㅛ, TT, ㅗ, ㅡ, 긴, ㅟ, ㅘ, ㅙ, ㅝ, ㅞ, ㅢ") may be input. Here, in the latter case, a long horizontal stroke may be input by pressing the number key 112 once when the consonant is input immediately after pressing the number key 112 twice. In addition, when the number key 112 is pressed twice in succession, a vowel in which two horizontal strokes of a double vowel are entered, for example, two horizontal strokes of “ㅑ, ㅕ, ㅒ, ㅖ” can be input at a time.

On the other hand, when the number 2 key 112 is pressed for a long time, when the long vertical stroke following the horizontal stroke is continuous, for example, a long horizontal stroke of “ㅚ, ㅟ, ㅘ, ㅙ, ㅝ, ㅞ, ㅢ” may be input. That is, by long pressing the number key 112, the problem that "ㅚ, ㅟ" is displayed as "ㅛ, ㅠ" can be prevented.

The example of the vowel input method described above is summarized in Table 3 below, and in the column of `` numeric key input method '' of Table 3, only one number is displayed, which means that the corresponding number key is pressed once. Duplicated expressions (e.g., "55") mean that the number key is pressed twice in succession, boldfaced bold type (e.g., " 2 ") means long press on the number key, Connected with “-” means press in order.

In addition, as mentioned above, there are three methods of operating the numbered keys 111 to 119, namely, simple one-time press, two consecutive presses, and long presses. In general, the one-time pressing time of users is about 0.1 seconds for adolescents or elderly users, and about 0.1 to 0.15 seconds for older users. Accordingly, in the character input method according to the present invention, when the key is pressed for a long time, the recognition time of the long press of the key is configured to be within a range of 0.3 seconds to 4 seconds. In addition, when the key is pressed twice in a row, it is recognized that even if the key is pressed twice in a row like a double-click operation of a computer mouse, the press is recognized twice even with a slight time difference. In particular, in the latter case, since the key pressed after two consecutive presses is different from the key pressed upon two consecutive presses, recognition of two consecutive presses is possible.

Meanwhile, referring to FIG. 1, the keypad 100 of a mobile communication terminal according to an exemplary embodiment of the present invention has keys 110 to 119, 121, and 122 arranged in four rows and three columns, and includes a first row and a second column. The vowel "-" for inputting the horizontal stroke of the vowel is assigned to the number 2 key 112, and the vowel "|" for inputting the vertical stroke of the vowel to the number 5 key of the second row of the second column. Is assigned, and the "*" function key, the "#" function key, and the number 0 key are arranged in the fourth row. However, the arrangement of the keypad according to the present invention is not limited to that shown in FIG. 1 and may be variously modified. For example, the "*" function key, the "#" function key, and the number 0 key arranged in the fourth row may be arranged in the first row, and the numeric keys of each column may be interchanged. Preferably, the vowel " ㅡ ”and vowel“ ㅣ ”should be configured to be assigned to the key of the second column. This is because when the user grabs the mobile phone with one hand and inputs Hangul, the movement distance of the thumb can be shortened.

Meanwhile, referring to FIG. 1, the Hangul input described above is performed after switching from the call mode to the Hangul input mode by operating a “menu” key, for example. When you want to call the special symbol, number or English input mode during Korean input, you can use "*" function key, 0 number key and "#" function key. For example, in the case of the "*" function key, when it is pressed once in the Hangul input mode state, it is comprised so that it may switch to the Hangul input mode by pressing it once more in the symbol input mode state. Also, in case of number 0 key, press once in Korean input mode to enter English uppercase input mode, press once more in English uppercase input mode to enter lowercase English input mode, and press once more in lowercase English input mode. It is configured to switch to Hangul input mode. In addition, the "#" function key is configured to switch to the numeric input mode when pressed once in the Korean input mode state and to the Korean input mode when pressed once again in the numeric input mode state.

In addition, in input mode conversion using the "*" function key, the number 0 key, and the "#" function key, the input mode switching may be variously performed between the modes. For example, if you want to enter uppercase English letters in the numeric input mode, press the number 0 key once, and if you want to enter the symbols in this state, press the "*" function key once, and then enter the lowercase English letters. If you want to press the number 0 key twice consecutively, if you want to switch to the Hangul input mode, press the number 0 key once.

As described above, according to the keypad and the character input method of the mobile communication terminal according to the present invention, since the various vowels can be divided into horizontal and vertical strokes in the vowel input, the vowels can be input in the order of stroke. A keypad and a text input method of a mobile communication terminal having no difficulty for a user to know a Hangul input method may be provided.

In addition, according to the present invention, since the input of the Hangul using only nine numeric keys 1 to 9, and the remaining zero numeric keys and the "*", "#" key is configured to be used as a function key for mode switching, A simpler keypad can be configured, and the use of the number 0 key, the "*" function key, and the "#" function key, which are unnatural to press during the Hangul input operation, can be greatly reduced from the user's point of view.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
