Description

Korean character input in mobile communication terminal

The present invention relates to a method of inputting Hangul characters using a keypad in a mobile communication terminal, and in particular, a character including at least Hangul using a keypad of a mobile communication terminal in which at least Hangul consonants and Hangul vowels are adaptively arranged. It relates to a Hangul character input method that can be input conveniently and efficiently.

In recent years, with the expansion of general wired communication services, technical development and subscription to personal wireless communication services such as Personal Communication Service (PCS) based on Code Division Multiple Access (CDMA) technology. Thanks to the drastic increase in embroidery, various additional services have been developed and are currently being actively serviced.

In particular, among these additional services, the Hangul transmission service is of particular interest to users due to the specificity of performing the Hangul transmission function through a voice communication terminal.

In order to provide such a Hangul transmission service, a useful Hangul input system that can easily input a Hangul through a Hangul keyboard such as a keypad of a mobile communication terminal is required, and the Hangul input system can display all Hangul syllables that can be represented by the Hangul alphabet. The degree of convenience of comprehensive operation such as rich character expressive ability to express uniquely, simple key operation and easy understanding of Hangul keyboard layout when the user directly reproduces the character expressive ability. The higher the number, the better its availability.

In addition to the Hangul transmission service, the application field using the Hangul code input method using the keypad part is connected to the stock information telephone service via telephone, and then, when the desired company name is entered, it can be applied to the stock information service that informs the price. Applications include various telephone voice information retrieval systems such as library collection guides, ticket reservations, and unattended 114 services. Other applications include small notebooks, such as electronic notebooks and palm top computers. And a keyboard system as a substitute for a general keyboard system, an operation such as an Internet TV, a digital still camera, and an input device, and an input system having a similar structure and function, such as an electronic lock and an automatic teller machine.

In order to provide Hangul transmission service using a reduced size Hangul keyboard with a limited number of key buttons, such as the keypad of a mobile communication terminal, the alphabet of the language to be supported can be effectively duplicated on an electronic telephone keypad or a function key can be operated. By the user's intention, it should be able to quickly extract or combine the desired Hangul alphabet.

The method used for inputting Korean characters in such a general mobile terminal is to store all completed characters in memory and use them, and to input the consonants and vowels of "Cheon (·) 지 (ㅡ) 인 (ㅣ)" separately. It is a general view that a method of completing letters is used, and that the "Cheonjiin" method is much more convenient than the method of storing all completed letters in a memory and using them.

FIG. 1 is a diagram illustrating an arrangement relationship between a keypad, a consonant, and a Korean character of a vowel of a general mobile communication terminal.

As shown in the figure, the "Cheonjiin" input method, in the keypad 200 of the mobile communication terminal 100 distinguishes the buttons of consonants and vowels, "1, 2, 3" button corresponding to the vowel | ·, ㅡ ”character is assigned, and“ 4 ~ 9, 0 ”button assigns consonants to input Hangul.

On the other hand, "ㄲ, ㄸ, ㅆ, ㅉ" is to press the number three times (in the case of 'ㄲ', '4' button three times in a row). In the input of the vowels, all vowels are composed of a combination of a vertical line (ㅣ), a horizontal line (ㅡ) and a dot (·), and "ㅏ" denotes the number key button "1" of the keypad 100 of the terminal 100. -2 "," ㅓ "is" 2-1 "," ㅐ "is" 1-2-1 "and so on. For example, to complete the text "My", you must press "5-1-2-1" consecutively. To complete the text "Release", press "5-2-3-1-2" consecutively. Should give.

As described above, the Korean character input method using "Cheonjiin" completes the letter by a combination of consonants and vowels, and in particular, since all three vowels can be expressed with only three buttons, it is easy to input letters on the mobile communication terminal 100. On the side.

However, since various vowels must be represented by only three buttons, it is inconvenient to press a button from at least two times up to five times. For example, in order to input "Lyn" in "Lynx", you have to press "4-4-2-3-1-2-1-0" in order and you need 5 buttons to input vowel. Has a very inconvenient and inefficient problem in that the same key must be repeatedly pressed several times to use the input key for inputting Korean characters.

In addition, in the case of other methods, consonants should be input up to three times and vowels up to four times, and the problem of pressing a maximum of ten times to complete a letter.

Accordingly, the present invention is proposed to solve the above problems of the prior art,

It is an object of the present invention to conveniently and efficiently complete characters containing at least Korean characters in all kinds of telephones by using a keypad of a mobile communication terminal of a telephone type in which at least Korean consonants and Korean vowels are uniformly arranged. The present invention provides a method of inputting Hangul characters in a mobile communication terminal that enables input, arranges consonants and vowels that are easy to remember or find, and facilitates input of Hangul characters using the same.

The present invention for achieving the above object,

Press “a, ㄲ, ㅗ / ㅚ” for button 1 of the keypad of the mobile communication terminal, “b, ㄶ, ㅛ / ㅘ” for button 2, and “b, ㄸ, NA / ㅙ” for button 3 , Button 4, "ㄹ, ㅀ, TT / ㅟ", button 5 "ㅁ, ㅠ / ㅝ", button 6 "ㅂ, ㅃ, ㅡ / ㅞ", button 7 and "ㅅ , ㅆ, ㅏ / ㅐ "," #, ㅑ / ㅒ "for button 8," ㅈ, ㅉ, ㅣ / ㅢ "for button 9," 1st collection mode switch button,, for button 0, / ㅖ ", * Function buttons" ·, ㅓ / ㅔ ", # Function buttons" Second vowel mode switch button ", and Hangul characters are input using this method. It is done.

In addition, each numeric key of the keypad portion of the mobile communication terminal corresponds to a consonant and "ㅋ, ㅌ,,, ㅎ" is input by pressing the "*" after pressing the consonant as a feature of the method configuration do.

In addition, by applying the "first vowel mode" button assigned to the numeric key 0 of the keypad in the mobile communication terminal, input of a single vowel "ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ" Press the first vowel mode switching button (0) once, and then input a single vowel by pressing the number key corresponding to each single vowel, and apply the "second vowel mode" button assigned to the function key # of the keypad. When the double vowel “ㅐ, ㅔ, ㅒ, ㅖ, ㅚ, ㅘ, ㅙ, ㅟ, ㅝ, ㅞ, ㅢ” is pressed, the second vowel mode switching button (#) is pressed once and corresponds to each of the double vowels. Entering a double vowel by pressing a numeric key is characterized by its methodological construction.

In addition, "ㄶ" and "ㅀ" assigned to the 2nd and 4th keys of the keypad, respectively, are the most commonly used double support consonants when inputting Korean characters, and double support by reducing the time required to input each of the consonants. It is characterized in that the method configuration that can be changed and input according to the user.

Hereinafter, preferred embodiments of the method for inputting Korean characters in a mobile communication terminal according to the above technical concept will be described in detail with reference to the accompanying drawings.

First, it is difficult to input Korean characters in a mobile communication terminal. To express various consonants and vowels, the consonant input and vowel input keys are separated separately. The number of keystrokes is increased. Accordingly, the present invention uses the input keys of the consonants and vowels without being separated, and sets two "modes" in the vowel input to prevent confusion between the consonants and the vowels.

Figure 2 is an exemplary view showing a preferred embodiment of the keypad unit in the mobile communication terminal according to the present invention, the arrangement of consonants and vowels used in the present invention with respect to the keypad (keypad) of the mobile communication terminal.

As shown in the figure, each numeric key of the keypad unit 300 corresponds to a consonant, and "ㅋ, ㅌ, ㅊ, ッ, ㅎ" is inputted by pressing the "*" button after pressing the corresponding consonant, In the display, the single vowel "ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ" is inputted using the number button "0", which is the "first vowel mode 310" button. , Double bar "ㅐ, ㅔ, ㅒ, ㅖ, ㅚ, ㅘ, ㅙ, ㅟ, ㅝ, ㅞ, ㅢ" is entered using the function key "#" key button which is the "second vowel mode 320" button .

On the other hand, "NA" displayed on the key button "3" of the keypad unit 300 means Not Applicable, which means that when there is an input of the second collection mode switching button 320, It indicates that there is no character designated for a single vowel, and is to prevent an error in input of the first and second switch buttons 310 and 320.

In addition, the reason why "ㄶ" and "ㅀ" are arranged on the key button is for convenience in key input.

A more detailed description of the above-described Hangul character input is as follows.

First, the input method for consonants in the Hangul character input method using the keypad 300 in the mobile communication terminal 100 is as shown in Table 1 below, and the input order is numeric or "*, #". It means that press corresponding to consecutively.

As shown in Table 1, it can be seen that consonants used in the head of letters can be made by a maximum of two key inputs.

Next, the input method for the double consonant consonants in the Hangul character input method using the keypad unit 300 in the mobile communication terminal 100 is as shown in Table 2 below, where "ㄶ" and "ㅀ" Can be entered in two cases.

In other words, the "ㄶ" is input by pressing the number key '2' twice in the keypad part in succession to select the predetermined character (ㄶ), or the number key '2 (b)', the number key '8 (ㅇ) '', by pressing the function key '* (·)' in sequence can be input double support according to the user's convenience, the "ㅀ" is pressed twice in the keypad number 4 '4' consecutively Select and input the preset character (ㅀ), or double-tap by pressing the number key '4 (ㄹ)' number, '8 (o)' number key, '* (·)' function key sequentially Can be entered according to the user's convenience.

Next, the input method for the vowel in the Hangul character input method using the keypad 300 in the mobile communication terminal 100, a single vowel "ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, "|" Is input by first pressing the "first vowel mode (number '0' button) 310" "on the keypad 300 and then pressing a corresponding key, and the double bar" ㅐ, ㅐ, ㅒ, ㅖ, ㅚ, ㅘ, ㅙ, ㅟ, ㅝ, ㅞ, ㅢ "and the like are input by first pressing the" second vowel mode (function '#' button) 320 "and then pressing the corresponding key. Therefore, all kinds of vowels can be represented by only two keystrokes. To enter a vowel, you must first press "0" or "#".

Table 3 attached below is a table of the above-described vowel input method.

As shown in Table 3, all vowels can be completed by two keystrokes.

2, the reason for arranging the vowels in the arrangement of the vowels in the arrangement of the vowels without the order of the Korean dictionary is as follows: "1 (,)", "2 (ㅘ)", "3 (ㅙ)", etc. It is arranged according to the number of strokes so that it is easy to remember a relatively complicated arrangement, and the arrangement of the vowels can be changed in a more easily memorable manner.

As described above, Hangul characters have the form of "consonants-vowels" or "consonants-vowels-consonants", and confusion arises as to whether the consonants following the vowels will be used as a consonant or the consonants of the next letter. In this case, the rule follows the input rule of the "double" keyboard of the general Hangul word processor.

On the other hand, the Hangul character input method in the above-described mobile communication terminal according to the present invention follows the following input rules.

First, the beginning of a sentence always starts with the input of consonants, the first consonant character entered after the vowel is recognized as the first consonant, and the second consonant following the first consonant is recognized as the double consonant consonant. The consonant following the consonant is used as the consonant of the next letter, and if there is a vowel following the single consonant consonant or double consonant consonant, the first or second consonant used as a consonant has the principle of going to the next consonant.

On the other hand, an embodiment of the Hangul character input method according to the present invention as described above is briefly illustrated as follows.

<Example>

"Hello": "ㅇ (8)"-"ㅏ (0-7)"-"ㄴ (2)"-"ㄴ (2)"-"ㅕ (0-0)"-"ㅇ (8)"

"Lyn": "ㅋ (1- *)"-"ㅙ (# -3)"-"ㅇ (8)"

According to the present invention described above, the method for inputting Korean characters in a mobile communication terminal, the method of inputting Korean characters using a keypad of a mobile communication terminal is adaptively adapted to each numeric key button with a minimum of Korean consonants and a Korean vowel uniformly. Using the keypad of the arranged phone type has the advantage that it is possible to completely input the characters containing at least Hangul characters very conveniently and efficiently.

In addition, the character input method has a short fingering distance (편리), the number of strokes (打 件 數) is reduced and the usage method is intuitively understood, so it is very convenient to use and has the advantage of efficiently entering Korean characters. .

In addition, it has the advantage that it is easy to store and find the Korean keyboard, and has the advantage that it can be easily applied to all character input systems, such as a portable telephone terminal, a conventional wired telephone terminal and a terminal having a telephone type keypad. .
