Description

Hangul input method {METHOD FOR INPUTTING THE HANGUL ALPHABET}

The present invention relates to a preferred Hangul input method to be applied to a telephone such as a mobile communication terminal, and more particularly, by assigning one or more Hangul alphabets to a plurality of keys, respectively. It relates to a Hangul input method for inputting in combination.

The mobile communication system transmits a call message including the unique number of the mobile communication terminal through the call control channel of the base station and provides a communication path wirelessly when a response is received from the corresponding terminal, thereby providing convenience and mobility of the telephone call at a long distance. The purpose is to seek.

In particular, such a mobile communication system has been able to provide data communication in recent years by adopting a digital communication method, thereby providing various services such as short message service, e-mail, and chat through data communication. .

As a result, several methods for inputting English, Korean, and special characters as well as numbers using a dialing keyboard have been proposed in mobile communication terminals, and Cheonjiin can enter all vowels using three keys among Korean input methods. Hangul input method is currently recognized as the most efficient Hangul input method.

4 is a layout diagram of the Hangul alphabet of the dialing keyboard to which the Korean input method is applied according to the prior art.

On the dialing keyboard, one or two Hangul consonants or vowels corresponding to the corresponding key can be entered in the dialing keyboard. For example, "ㅣ" for 1, "·" for 2, "ㅡ" for 3, and 4 for "ㄱ, ㅋ", 5 "ㄴ, ㄹ", 6 "ㄷ, ㅌ", 7 "ㅂ,", 8 "ㅅ, ㅎ", 9 "ㅈ, ㅉ", 0 "ㅇ , ㅁ "is indicated.

In such a state, when a telephone number is input for a call, a number is inputted by dialing a key designated with the number in the same manner as using a numeric input key of another device.

In case of inputting Hangul, a character is input by using a key arranged with a letter after switching from call mode to Hangul input mode by operating a separate function key.

In the case of inputting consonants, consonants written in the corresponding keys are sequentially selected according to how many times the numeric keys in which the consonants are arranged are continuously operated in the Hangul input mode.

For example, pressing the numeric key [4] once will display the first consonant "ㄱ" on the LCD, pressing [4] twice in succession will show "ㅋ", and pressing it three times in succession will return " "A" is displayed. If you press it four times in succession, "ㅋ" is displayed again.

In other words, if you keep pressing [4], "ㄱ", "ㅋ", "ㄱ", "ㅋ", "ㄱ", "ㅋ"…. These sequentially appear on the liquid crystal display, and when the desired consonant appears, the next consonant is input, a moving key ([*] / [#], etc.) is pressed, or when a certain time elapses, the currently selected consonant is input to the mobile communication terminal.

In the case of inputting vowels, in Korean input mode, one or three of the three digit keys on which vowels (thousand, ji, in) are arranged are inputted. .

However, the above-described Korean Hangul input method also has a limitation on the Hangul input speed, and the user of the mobile communication terminal expects the appearance of a better Hangul input method.

In particular, the vowel input procedure in Cheonjiin Hangul input method provides the function to input all vowels using three keys, but among the cloth (·), ji (ㅡ), and in (ㅣ) arranged on the vowel keys Since cloth (·) is a symbol rather than a complete vowel, vowels that require the input of cloth (·), such as ㅓ, ㅛ, 혼란, ㅛ, etc., are confusing to novice users because intact characters are not displayed. .

The present invention has been proposed to solve the problems of the above and the prior art, by assigning one or more alphabets of the Hangul alphabet to a plurality of keys, respectively, by inputting the Hangul alphabet by the input of the corresponding key, It is possible to input all vowels using only the key, which shortens the moving distance during key operation for character input. Also, any vowel input always displays the complete character so that novice user can use it easily. The purpose is to provide a method.

In the Hangul input method according to the present invention for realizing the above object, one or more consonants or vowels of the Hangul are assigned to a plurality of keys, respectively, and the Hangul is combined by inputting consonants and vowels through the corresponding keys. In the Hangul input method, “ㅣ” is named as a stem and “ㅡ” is called as a horizontal stem based on the shapes of the Hangul vowels, and other shapes of the shape following the stem are left and right based on the direction. When naming branches, branches, and branches, one or more stem input functions or branch input functions are assigned to the plurality of keys, respectively, and “ㅣ” and “ㅡ” in the vowels are vertical stem input functions, respectively. And the lateral stem input function, and other vowels except for “ㅣ” and “ㅡ” are inputted by combining at least two of the stem input functions and the branch input functions. It is characterized by.

According to another aspect of the present invention, the Hangul input method is a Hangul input method in which one or more consonants or vowels of the Hangul are assigned to a plurality of keys, respectively, and the Hangul is combined by inputting consonants and vowels through the corresponding keys. Based on the shapes of the Hangul vowels, "ㅣ" is named as a stem and "-" is called as a transverse stem. The other shapes of the shape following the stem are left, right, upper, In the naming, the stem input function or branch input function for inputting the short vowels of the vowels is assigned to the plurality of keys, respectively, and for inputting the number of strokes according to the shape of the double vowels in the vowels. A double vowel input function is assigned to any one of the plurality of keys, and " ㅣ " and "-" And the other short vowels except for the "|" and "-" are inputted by combining at least two of the stem input functions and the branch input functions, and when the double vowel is input from the vowels, the single vowels In the separated state, the first short vowel is input by the short vowel input method, and the remaining vowels are characterized by inputting a corresponding number of strokes to be additionally input using a double vowel input key.

There may be a plurality of embodiments of the present invention. Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

In addition, the technique of the present invention can be applied to various products capable of inputting characters by operating a dialing keyboard (or a numeric keyboard) such as a general telephone, a calculator or an automatic teller machine as well as a PCS phone and a cellular phone.

Thus, the reference drawings used in the description are not limited to a specific mobile communication terminal but are drawn from various character input apparatuses capable of inputting characters using a keyboard provided with numeric keys.

1 is a block diagram of a mobile communication terminal to which the Hangul input method according to the present invention can be applied.

Looking at the configuration-specific functions of the mobile communication terminal, the control unit 10 controls the overall operation of the mobile communication terminal. The memory 20 stores a character input program and a program for controlling the overall operation through the key input unit 70 of the mobile communication terminal, and data input and output when the overall operation of the mobile communication terminal is performed by the controller 10. And text message data transmitted from the text service system center in a predetermined area. The duplexer 30 communicates with the base station through the antenna AT, and separates a transmitted / received signal. The receiver 40 receives a radio signal input through the antenna AT under a predetermined control, receives a radio signal separated by the duplexer 30, amplifies, filters, and outputs a weak signal. The transmitter 50 filters, amplifies, and amplifies a radio signal output from the audio unit 60 under a predetermined control, and transmits it through the duplexer 30 through the antenna AT. The audio unit 60 modulates the voice signal input through the microphone MIC into a wireless signal under the control of the controller 10, and demodulates the wireless signal received through the receiver 40 to the speaker SP. It sends out as a signal. In addition, when a ring signal is generated from the base station, it detects the ring signal through the receiver 40 and transmits it through a ringer. The key input unit 70 includes a plurality of numeric keys and function keys. When the user presses a predetermined key, the key input unit 70 generates corresponding key data and outputs the corresponding key data to the controller 10 to enable input of numbers and characters. The display unit 80 includes a liquid crystal display (LCD) for displaying various kinds of information, is controlled by the controller 10, and the key data generated by the key input unit 70 and various information of the controller 10. The signal is received and displayed. The key input unit 70 is a dialing keyboard (see FIG. 2) to which the Korean input method of the present invention, which will be described below, and a key data generator for generating corresponding key data according to a user's operation and transmitting the generated key data to the controller 10 (not shown). It is done.

2 is a layout diagram of the Hangul alphabet of the dialing keyboard to which the Hangul input method according to the present invention is applied.

In the dialing keyboard according to the present invention, one or two Hangul consonants or vowels corresponding to the corresponding keys are provided in the dialing keyboard according to each numeric key, that is, "ㅣ" for 2, "ㅡ" for 3, and "ㄱ" for 4 , ㅋ "," ㄴ, ㄹ "for 5," ㄷ, ㅌ "for 6," ㅂ, ッ "for 7," ㅅ, ㅎ "for 8," ㅈ, ㅉ "for 9," ㅇ, ㅁ "Is indicated.

All vowels can be entered using two keys ("ㅣ" key, "ㅡ" key), so the key corresponding to the number 1 is a few special characters (".", " , ","！ ","? ").

Of course, the consonants, vowels, special characters, etc. of Korean characters assigned to the respective numeric keys can be changed as much as possible. This is just one embodiment and should be considered for ease of use.

In the dialing keyboard according to the present invention, when a telephone number is input for a call, the number is inputted when the corresponding key is dialed in the same manner as the method of using a numeric input key of another device.

In case of inputting Hangul, a character is input by using a key arranged with a letter after switching from call mode to Hangul input mode by operating a separate function key.

In the case of inputting consonants, consonants written in the corresponding keys are sequentially selected according to how many times the numeric keys in which the consonants are arranged are continuously operated in the Hangul input mode.

For example, pressing the numeric key [4] once will display the first consonant "ㄱ" on the LCD, pressing [4] twice in succession will show "ㅋ", and pressing it three times in succession will return " "A" is displayed, and if you press it four times in succession, "ㅋ" is displayed again.

In other words, if you keep pressing [4], "ㄱ", "ㅋ", "ㄱ", "ㅋ", "ㄱ", "ㅋ"…. These sequentially appear on the liquid crystal display, and when the desired consonant appears, the next consonant is input, a moving key ([*] / [#], etc.) is pressed, or when a certain time elapses, the currently selected consonant is input to the mobile communication terminal.

It can be seen that the Korean consonant input method described so far is the same as the Korean input method described with reference to FIG. 4 in the prior art description, which corresponds to a known technique that is the most basic of the character input methods using a mobile communication terminal. Detailed descriptions thereof will be omitted. The signal flow of the key input unit 70, the controller 10, and the memory 20 during Hangul consonant input will be easily understood through the signal flow during Hangul vowel input, which will be described below.

When entering a vowel, one or two of the two numeric keys where the vowels ("ㅣ", "ㅡ") are arranged are entered in the Korean input mode.

First, in describing the Hangul input method according to the present invention, terms to be used below will be defined to help convenience and understanding of the description.

As shown in Fig. 3, "ㅣ" is named as a stem and "-" is called as a lateral stem based on the shapes of the Hangul vowels, and other shapes of the shape following the stem are left and right based on the direction. Branches, upper branches, and branches are named.

Based on this, the Hangul input method according to the present invention has a vertical stem input key, a horizontal stem input key, a left branch input key, a right branch input key, an upper branch input key, and a lower branch input key. At least one of the six input keys is combined, but the stem input key is input first, followed by the branch input key. First, when the input process of "ㅓ" is described as an example, the vertical stem input key and the left branch input key are sequentially inputted.

<First Embodiment>

According to the preferred embodiment shown in Fig. 2, the numeric key [2] doubles as a vertical stem input key, a left branch input key and an upper branch input key, and the numeric key [3] has a horizontal stem input key and a right branch. It also functions as an input key and one input key.

First, when the vowel input process using only one key is described, the key data generator (not shown) of the key input unit 70 generates the corresponding key data according to the user's operation when the numeric key [2] is pressed once. The control unit 10 performs a vertical stem input function according to a result of comparison with a collection table for each key data based on a character input program stored in the memory 20. "Is displayed on the liquid crystal display window (display section).

Press [2] two times in succession to the left input function according to the same signal flow as above and “ㅓ” is displayed. Press three times in succession to perform the left input function again. If you press it four times in succession, it will go back to the beginning and only the seed stem input function will be executed.

In other words, keep pressing [2] to select “ㅣ”, “ㅓ”, “ㅕ”, “ㅣ”, “ㅓ”, “ㅕ”…. Appears sequentially on the liquid crystal display, and when the desired vowel appears, the next vowel is input, the shift key ([*] / [#], etc.) is pressed, or the selected vowel is input to the mobile terminal when a certain time elapses.

The signal flows of the key data generator (not shown) of the key input unit 70, the control unit 10, the memory 20, and the liquid crystal display (display unit) in all the vowel input processes to be described below are described above. Since the signal flow is the same as that of the vowel input, the description thereof will be omitted.

Next, press the numeric key [3] once to perform the horizontal stem input function. The first vowel “ㅡ” is displayed on the LCD, and press [3] twice in succession to perform the lower input function. ㅜ "is displayed, and if you press it three times in succession, one of the input functions is performed once more, and“ ㅠ ”is displayed, and if you press it four times in succession, it will go back to the beginning and only the horizontal stem input function is performed. Is displayed.

In other words, if you keep pressing [3], "ㅡ", "TT", "ㅠ", "ㅡ", "TT", "ㅠ"…. Appears sequentially on the liquid crystal display, and when the desired vowel appears, the next vowel is input, the shift key ([*] / [#], etc.) is pressed, or the selected vowel is input to the mobile terminal when a certain time elapses.

Next, in order to explain the vowel input process using two keys, the input process of "ㅑ" and "ㅛ" will be described sequentially.

In the input process of "ㅑ", press the numeric key [2] once to perform the bell stem input function, and "ㅣ" is displayed on the LCD, and press [3] once to perform the four kinds of input functions. "ㅏ" is displayed. Press [3] again to perform the input function once more. Then "ㅑ" is displayed. At this time, if you press [3] again, that is, if [ㅣ] is pressed three times in succession while "ㅣ" is displayed on the liquid crystal display, "ㅣ" is maintained, the same as the state where the input function is not performed. .

The input process of "ㅛ" is performed by pressing the numeric key [3] once to perform the horizontal stem input function, and "-" is displayed on the LCD, and pressing [2] once in this state also performs the same function. "ㅗ" is displayed, and press [2] again to execute the upper-level input function once more, and then "ㅛ" is displayed. At this time, if [2] is pressed again, that is, if [o] is pressed three times in succession while “o” is displayed on the liquid crystal display, the same “o” is maintained as in the state where no branch input function is performed. .

Table 2 shows a combination method for each vowel based on the Hangul input method according to the present invention as described above.

When entering vowels according to the vowel input principle as described above, the vowels of "ㅑ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅝ, 입력" are entered without error. However, if the vowel of "ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅞ, ㅢ" is input according to the same vowel input principle as described above, an error that an unwanted vowel is input is generated unlike in Table 2.

Here, looking at the commonalities of the vowels in which an error occurs when the input is an error occurs when trying to continuously use the input function assigned to the same numeric key, for example, when you want to enter the "ㅔ" and the bell stem input function The left branch input function and the vertical stem input function should be performed sequentially, but the last vertical stem input function is performed as the left branch input function, and an error of inputting "ㅕ" occurs.

Accordingly, in case of inputting a double vowel in which an input error occurs, the next digit key must be continuously operated after inserting a vowel separation command using a predetermined pause time (□) in the input section in which the error occurs. Of course, if the user wants to input faster, such as known technology, do not use the pause time (□), but press the shift key ([*] / [#], etc.) or set the key input time to enter the next time. You can substitute them in a way that separates them from the vowels that become.

As such, the user may have an idle time (□) when inputting the corresponding vowels to avoid an error in a state in which the vowels in which the error does not occur and the vowels in which the error occurs are determined, but this may cause inconvenience in use. Therefore, when the user inputs all the vowels, the user divides the vowels to be input into short vowels and inputs the short vowels sequentially. Inconvenience to prevent the occurrence of errors during input is eliminated.

As an example, a case in which "ㅣ" [2], "-" [3], and "ㅣ" [2] is manipulated when inputting "ㅐ" will be described.

"ㅣ" [2] has a vertical stem input key function, a left branch input key function, and an upper branch input key function, but since the vowel key is operated for the first time, the control unit 10 performs the vertical stem input key function to display the display unit ( 80) is displayed as "ㅣ".

Next, "-" [3] has a horizontal stem input key function, a right input key function, and a lower input key function, but since the vertical stem is previously input, the horizontal stem cannot be input subsequently. Therefore, the control unit 10 should recognize either one of the right stem or the bottom stem, but since the previous input is the longitudinal stem, the controller 10 performs a right stem input key function and displays "ㅏ" on the display unit 80.

"ㅣ" [2] has a vertical stem key function, a left branch input key function, and an upper branch input key function. However, since the input "ㅏ" cannot include the left branch and upper branch, the control unit 10 has a vertical stem. "ㅐ" is displayed on the display unit 80 by performing an input key function.

Here, a case where the user manipulates "ㅣ" [2] after having a pause time (□) in the state of operating "ㅣ" [2] and "ㅡ" [3] sequentially, "ㅣ" [2] And "ㅏ" are displayed by the sequence of "-" [3]. If "ㅣ" [2] is operated following the elapse of the pause time (□) in this state, the "ㅏ" input so far is left. Since the branch and the upper branch cannot be included, the control unit 10 performs the vertical stem input key function among the vertical stem input key function, the left branch input key function, and the upper branch input key function. Even if the separation is commanded, no character begins with the vowel, so the control unit 10 includes the stem stem key input function in the previously separated character, so that "ㅐ" is displayed on the display unit 80.

In addition, the vowels of “ㅖ, ㅖ, ㅘ, ㅙ, ㅞ, ㅢ, ㅢ” may be implemented to be input in other ways. First, the shape combination sequence is summarized in Table 3.

collection Combination Order Key operation count ㅔ ㅣ (종), ㅣ (left), <ㅓ> (bok) 3 ㅖ ㅣ (종), ㅣ (left), ㅣ (left), <ㅕ> (bok) 4 ㅘ ㅡ (lateral), ㅣ (up), <ㅗ> (bok), (bok) 4 ㅙ ㅡ (lateral), ㅣ (up), <ㅗ> (bok), (bok), (bok) 5 ㅚ ㅡ (lateral), ㅣ (up), <ㅗ> (bok) 3 ㅞ ㅡ (lateral), ㅡ (하), <TT> (Bok), (Bok), (Bok) 5 ㅢ ㅡ (lateral), <ㅡ> (bok) 2

Referring to the input method of Table 3, six types of vowel input keys, such as the vertical stem input key, the horizontal stem input key, the left branch input key, the right branch input key, the upper branch input key, and the lower branch input key, are described. Is a method of using a double vowel input key separately.

In case of inputting a vowel vowel which may cause an error, the first vowel divided into vowels is input by combining the stem input key and the branch input key as described above, and the remaining vowels are the double vowel input key. Enter the number of strokes to be additionally typed using.

For example, looking at the input process of "ㅘ, ㅙ, ㅚ", if you select [3] ㅡ (horizontal) and [2] ㅣ (up), <ㅗ> is currently entered, and the vowel input key is 1 Once selected, the current "ㅗ" is changed to "ㅚ" and is entered. If the user selects the double vowel input key once more (total 2 times), the current "ㅚ" is changed to "ㅘ" and entered. If the key is selected again (3 times in total), the current "ㅘ" changes to "ㅙ" and is input. In this case, if the vowel input key is selected four times in total, the reset function is exerted to change the input state of the first vowel "ㅗ".

For this embodiment, when the vowel vowel input keys are arranged on the dialing keyboard as shown in FIG. 2, the vowel input keys may be assigned to other keys except for the numeric keys on which the consonants and vowels are arranged. Among the assigned number keys of [2] and [3], when inputting a specific double vowel, the remaining key other than the final key for inputting the first short vowel performs the function of the double vowel input key.

In other words, the double vowel input function for input of "ㅔ, ㅖ, ㅘ, ㅙ, ㅚ" is performed by the [3] key, and the double vowel input function for the input of "ㅞ, ㅢ" is performed by the [2] key. Is performed.

By the way, when [2] key is operated to input the double vowel in the state of inputting “ㅡ” by the horizontal stem input key during the input of “ㅢ”, an error occurs that short vowel “ㅗ” is inputted as shown in Table 2. do. Therefore, when the double vowel input key is applied, the input of "ㅗ" and "ㅛ" is different from the other short vowel inputs, thereby preventing an input error.

Specifically, in the input process of "ㅗ" and "ㅛ", when the numeric key [3] is pressed once, the horizontal stem input function is performed, and "-" is displayed on the liquid crystal display window, and [2] is pressed once in this state. Press to execute the upper branch input function and display "ㅗ". Press [2] again to execute the upper branch input function again and display "ㅛ". At this time, pressing [2] again, that is, pressing [2] three times in succession while "-" is displayed on the liquid crystal display causes the double vowel input function to be performed to display "ㅢ". At this time, if you press [2] again, that is, if you press [2] four times in succession while "-" is displayed on the LCD, the same as in the case where neither the upper branch input function nor the vowel input function is performed, ㅡ "is maintained.

It is also possible to use a dedicated input key for input of the "ㅢ" vowel. Preferably, the "ㅢ" dedicated input function is given to the numeric key [1] to which a special character is assigned in the dialing keyboard shown in FIG. Of course, the "ㅢ" input function and the special character input function can be given to the numeric key [1] so that the "ㅢ" vowel and the special character are sequentially changed and input according to the number of operations.

Second Embodiment

As described above, in the first embodiment, the numeric key [2] also functions as the vertical stem input key, the left branch input key and the upper branch input key, and the numeric key [3] enters the horizontal stem input key and the right branch input key. It also functions as a key and one input key.

However, this is only an embodiment in which all vowels can be inputted with only minimal keys. The vertical stem and horizontal stem input functions are assigned to different keys, and the left and right input functions are different from each other. The above input functions may be assigned to any other key as long as it is assigned to another key and the principle of assigning the upper and lower input functions to the different keys is acceptable.

In the second embodiment to be described below, the numeric key [2] serves as the vertical stem key, the left branch key, and the lower branch key, and the numeric key [3] is the horizontal stem key. The case of serving as the function of the four input keys and the upper input key will be described.

Compared to the first embodiment, the second embodiment replaces the assignment keys of the upper branch input function and the lower branch input function. In the second embodiment, a single vowel “ㅗ, ㅛ” is input by one key. These vowels are much more frequently used in Korean sentences than the short vowels "TT, ㅠ" which can be input by one key in the first embodiment, thereby further improving the character input speed.

The vowel input principle of the second embodiment is the same as that of the first embodiment, and the vowel combination sequence for each vowel based on the Hangul input method according to the second embodiment of the present invention is summarized in Table 4 below.

General vowel input process will be easily understood with reference to the above-described first embodiment and Table 4, so a detailed description thereof will be omitted, and an exception rule will be described below.

If you enter the vowels according to the order of the shape combinations of Table 4, the vowels of "ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅘ, ㅙ, 없이" are without errors. Although it is possible to input the vowel of "ㅔ, ㅖ, ㅝ, ㅞ, ㅟ, ㅢ", unlike Table 4, an error that an unwanted vowel is input is generated.

Here, looking at the commonalities of the vowels in which an error occurs when the input is an error occurs when you want to continuously use the input function assigned to the same numeric key, for example, when you want to enter "ㅔ" The left branch input function and the vertical stem input function should be performed in sequence, but the last vertical stem input function is performed as the left branch input function and an error of "ㅕ" is inputted.

Accordingly, when inputting a vowel vowel in which an input error occurs, as described in the first embodiment, after the vowel separation command is inserted using a predetermined pause time (□) in the input section in which the error occurs, the next vowel is continued. Use the numeric keys. Of course, if the user wants to input faster, such as known technology, do not use the pause time (□), but press the shift key ([*] / [#], etc.) or set the key input time to enter the next time. You can substitute them in a way that separates them from the vowels that become.

As such, the user may have an idle time (□) when inputting the corresponding vowels to avoid an error in a state in which the vowels in which the error does not occur and the vowels in which the error occurs are determined, but this may cause inconvenience in use. Therefore, when the user inputs all the vowels, the user divides the vowels to be input into short vowels and inputs the short vowels sequentially. Inconvenience to prevent the occurrence of errors during input is eliminated. This has already been described through the first embodiment.

In addition, the vowels "ㅔ, ㅖ, ㅝ, ㅞ, ㅟ, ㅢ" may be implemented to be input in other ways. First, the shape combination sequence is summarized in Table 5.

collection Combination Order Key operation count ㅔ ㅣ (종), ㅣ (left), <ㅓ> (bok) 3 ㅖ ㅣ (종), ㅣ (left), ㅣ (left), <ㅕ> (bok) 4 ㅝ ㅡ (lateral), ㅣ (bottom), <TT> (bok), (bok) 4 ㅞ ㅡ (lateral), ㅣ (bottom), <TT> (bok), (bok), (bok) 5 ㅟ ㅡ (lateral), ㅣ (bottom), <ㅜ> (bok) 3 ㅢ ㅡ (lateral), <ㅡ> (bok) 2

The input method of Table 5 is the same principle as the input method of Table 3, and the vertical stem input key, horizontal stem input key, left branch input key, right branch input key, upper branch input key, lower branch input key and the like as described above In addition to the six vowel input keys, the method of using double vowel input keys.

In case of inputting a vowel vowel which may cause an error, the first vowel divided into vowels is input by combining the stem input key and the branch input key as described above, and the remaining vowels are the double vowel input key. Enter the number of strokes to be additionally typed using.

For example, if you look at the input process of "ㅝ, ㅞ, ㅟ", if you select [3] ㅡ (horizontal) and [2] ㅣ (bottom), <tt> is currently entered, then the vowel input key is 1 When selected times, the current "TT" is changed to "ㅟ" and is inputted. If the user selects the double vowel input key once more (total 2 times), the current "TT" is changed to "ㅝ" and inputted. If the key is selected again (3 times in total), the current "TT" is changed to "ㅞ" and entered. If the vowel input key is selected four times in total, the reset function is exerted to change the input state of the first vowel "TT".

For this embodiment, when the vowel vowel input keys are arranged on the dialing keyboard as shown in FIG. 2, the vowel input keys may be assigned to other keys except for the numeric keys on which the consonants and vowels are arranged. Among the assigned number keys of [2] and [3], when inputting a specific double vowel, the remaining key other than the final key for inputting the first short vowel performs the function of the double vowel input key.

In other words, the double vowel input function for input of "ㅔ, ㅖ, ㅝ, ㅞ, ㅟ" is performed by the [3] key, and the double vowel input function for the input of "ㅢ" is performed by the [2] key. .

By the way, when [2] key is operated to input the double vowel in the state of inputting “ㅢ” by the horizontal stem input key, the short vowel “TT” is inputted as shown in Table 4. do. Therefore, when the double vowel input key is applied, the input of "TT" and "ㅠ" is different from the other short vowel inputs, thereby preventing an input error.

Specifically, in the input process of "TT" and "ㅠ", when the numeric key [3] is pressed once, the horizontal stem input function is performed, and "-" is displayed on the liquid crystal display window, and [2] is pressed once in this state. If it is pressed, it executes up to one input function and "TT" is displayed. If you press [2] again, the input function is performed once again and "ㅠ" is displayed. At this time, pressing [2] again, that is, pressing [2] three times in succession while "-" is displayed on the liquid crystal display causes the double vowel input function to be performed to display "ㅢ". At this time, if you press [2] again, that is, if you press [2] four times in succession while “ㅡ” is displayed on the LCD, the same function as in the case where neither the input function nor the vowel input function is performed, ㅡ "is maintained.

In addition, as in the first embodiment, a dedicated input key for inputting a "의" vowel may be used. Preferably, "ㅢ" is dedicated to the numeric key [1] to which a special character is assigned in the dialing keyboard shown in FIG. Give an input function. Of course, the "ㅢ" input function and the special character input function can be given to the numeric key [1] so that the "ㅢ" vowel and the special character are sequentially changed and input according to the number of operations.

Third Embodiment

The third embodiment of the present invention is a case where the vowel vowel input keys applied at the time of inputting some vowel vowels in the first and second embodiments are extended to all the vowel inputs.

In the third embodiment, the vertical stem input function and the horizontal stem input function are assigned to different keys, the left branch input function and the right branch input function are assigned to different keys, and the upper branch input function and the lower branch input function are assigned. As long as the principle of assigning to the different keys is observed, the above input functions may be assigned to any key. For example, as in the second embodiment, the numeric key [2] is the vertical stem key and the left key. Functions as a lower input key, numeric key [3] also functions as a horizontal stem input key, a right input key and an upper input key, and uses a double vowel input key separately from the six vowel input keys. I will explain.

According to the third embodiment of the present invention, when inputting a single vowel, the input process is performed in the same principle and method as in the first or second embodiment, and when all the double vowels are input, the corresponding vowels are divided into short vowels. The first short vowel is input by combining the stem input key and the branch input key of the first and second embodiments, and the remaining vowels are inputted by using the vowel input key. will be.

Table 6 below shows the arrangement order of the vowel shapes for each vowel based on the Hangul input method according to the third embodiment of the present invention.

Comparing the vowel combination order of each vowel in Table 6, it can be seen that there is no duplicate vowel, which indicates that no error occurs during input of all vowels. Since each vowel-shaped combination process has been described through the first and second embodiments, a detailed description thereof will be omitted.

In addition, when the vowel vowel input keys are arranged on the dialing keyboard as shown in FIG. 2, the vowel input keys may be assigned to other keys except for the numeric keys where consonants and vowels are arranged. Preferably, six vowel input keys are assigned [2]. ] When inputting a specific double vowel among the numeric keys of [3], the remaining key other than the final key for inputting the first short vowel performs the function of the double vowel input key.

In other words, the double vowel input function for input of "ㅔ, ㅖ, ㅝ, ㅞ, ㅟ" is performed by the [3] key, and the double vowel input for the input of "ㅐ, ㅒ, ㅘ, ㅙ, ㅚ, ㅢ". The function is performed by the [2] key.

By the way, when [2] key is operated to input the double vowel in the state of inputting “ㅢ” by the horizontal stem input key, the short vowel “TT” is inputted as shown in Table 6. do. Therefore, when the double vowel input key is applied, the input of "TT" and "ㅠ" is different from the other short vowel inputs, thereby preventing an input error.

Specifically, in the input process of "TT" and "ㅠ", when the numeric key [3] is pressed once, the horizontal stem input function is performed, and "-" is displayed on the liquid crystal display window, and [2] is pressed once in this state. If it is pressed, it executes up to one input function and "TT" is displayed. If you press [2] again, the input function is performed once again and "ㅠ" is displayed. At this time, pressing [2] again, that is, pressing [2] three times in succession while "-" is displayed on the liquid crystal display causes the double vowel input function to be performed to display "ㅢ". At this time, if you press [2] again, that is, if you press [2] four times in succession while "-" is displayed on the LCD, the same as in the case where neither the input function nor the vowel input function are performed, ㅡ "is maintained.

In addition, as in the first and second embodiments, a dedicated input key for inputting a "ㅢ" vowel may be used. Preferably, a numeric key [1] to which a special character is assigned in the dialing keyboard shown in FIG. Give "ㅢ" a dedicated input function. Of course, the "ㅢ" input function and the special character input function can be given to the numeric key [1] so that the "ㅢ" vowel and the special character are sequentially changed and input according to the number of operations.

Table 7 below shows the remaining keys other than the final key for inputting the first short vowel when inputting a specific double vowel among the numeric keys of [2] and [3] to which 6 types of vowel input keys are assigned as described above. When performing a function, the vowel combination order of each vowel is summarized to indicate that no erroneous combination sequence exists in all vowel inputs.

Or less, Table 8 summarizes the shape combination process for inputting the same example sentences in order to compare the present invention and the prior art.

-Conventional technology: Korean input method of the conventional heaven and earth described through FIG.

-In the present invention: As an example described in the third embodiment, the numeric key [2] functions as the vertical stem input key, the left branch input key and the lower branch input key, and the numeric key [3] is the horizontal stem input key and the right side. It also functions as the branch input key and the branch input key, and among the numeric keys of [2] and [3] assigned with six kinds of vowel input keys, the remainder other than the final key for inputting the first short vowel when a specific double vowel is input. Key performs the function of double vowel input key.

Comparing the prior art and the present invention in Table 8, it can be seen that the number of keys for inputting the example sentence is the same, and the present invention is superior in the continuity of the same key for inputting the same example sentence. As such, the present invention provides two sources that can improve the character input speed as compared to the prior art. That is, unlike the prior art in which the vowel input function is assigned to three numeric keys, all the vowel input functions are assigned to the two numeric keys, and the continuity of the same key is high when the vowel input is performed.

In the above description, but limited to one embodiment of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art. Such modified embodiments should be included in the technical spirit described in the claims of the present invention.

As described above, according to the preferred embodiment of the present invention, all vowels can be input using only two keys, so that the movement distance at the time of key manipulation for character input has the shortest distance.

Comparing Table 1, which summarizes the vowel combination order of the vowels in the Korean input method according to the prior art, and Table 2, which summarizes the vowel combination order of the vowels in the Korean input method according to the present invention, the number of key operations is the same in all vowels In terms of the number of keys used, it can be seen that the Hangul input method according to the present invention is significantly less. As a result, when moving the vowel, the movement distance of the key operation is shortened, thereby providing a fast character input speed.

In particular, in case of a sentence containing a large number of vowels that can be input by one key, the input speed is doubled. In most Korean sentences, the short vowel "ㅓ, ㅕ, ㅗ, ㅛ, (TT, ㅠ)" The frequency of use is much higher than that of vowels, which increases the speed of text input.

In addition, looking at the Hangul alphabet arrangement diagram according to the present invention shown in Figure 2 it can be seen that there is an extra one even if the Hangul alphabet is placed on the numeric keys 0 to 9. In the embodiment of the present invention, since a few special characters having a high frequency of use when inputting Korean characters are assigned to these extra keys, when inputting Korean sentences containing such special characters, they are relatively fast compared to the conventional Korean input method. Obviously, you can enter sentences.

In addition, the Hangul input method according to the present invention has an effect that even a novice user can easily use since the entire character is always displayed on the liquid crystal display window even when any vowel is input.
