Description

Hangul input method and communication terminal device therefor {METHOD FOR INPUTTING HANGUL AND COMMUNICATION TERMINAL APPARATUS FOR THE SAME}

The present invention relates to a Hangul input terminal, and more particularly, to a Hangul input method that can more easily and quickly input the consonants, vowels of Hangul.

As the performance of computer systems becomes more complex and up-leveled, usability issues are now more important than functional competition. In addition, there is a problem of which type of input device is more efficient in using a system having the same performance, and a problem in which interface is more usable in the same input device. One of the issues is the touchscreen method. The touch screen method is the most direct method among existing input devices, and a user performs a task by directly selecting a menu or an icon on the display with his finger or a stylus pen.

Recently, touch screen phones have been released one after another, and products in various fields such as MP3 players, TV remote controls, and GPS as well as mobile phones are adopting touch screen technology to introduce new UI (User Interface) and designs. Softkeys, unlike conventional hardkeys, do not have a fixed physical structure, but are supported by a specific program or system operating system. Recently, softkeys have been in the spotlight with the development of touch screen technology. As many devices such as mobile phones adopt the touch screen method, the development of the touch screen and the use of the softkeys for input therein also increase. The soft key input method is different from the conventional hard key input method, and by using both hands, the user selects one by one finger or a stylus pen while pressing a key of a predetermined position for each finger. Therefore, despite the need to support different interfaces depending on the input method difference, most devices still follow the existing hard key input method.

Unlike a hard key, a soft key has no standard, and thus is limited in its application by its learning and popularity, and does not have a physical structure, thereby freeing its configuration. Therefore, if you configure the optimal key arrangement, you can expect better usability.

In the conventional method of inputting Hangul consonants by hard keys, the number of phonemes to be input when the consonants (for example, 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ') are included in the initial consonant or the final consonant It took a lot of time to input Korean consonants. In addition, Fujong consonants such as 'ㄳ', 'ㄵ', 'ㄶ', 'ㄺ', 'ㄻ', 'ㄼ', 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ', 'ㅄ' ), The number of phonemes to be input increased due to the combination of consonants.

In addition, the Hangul vowel input method using the Cheonjiin (eg '·', 'ㅡ', 'ㅣ') method through hard keys increases the number of phonemes to be input due to the combination of the vowels, and thus it takes a long time to input the Hangul vowels. Was taken. As another example, the Hangul vowel input method using the hard key may be a basic short vowel (eg 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ') or a basic double vowel (neutral) in the neutral (vowel). For example, a short vowel such as "ㅐ", "ㅔ", or a double vowel such as "ㅒ", "ㅖ", but not a "ㅑ", "ㅕ", "ㅛ", "ㅠ"), or a double vowel (eg 'ㅘ', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅢ') increases the number of phonemes that need to be entered due to the combination of vowels. This took

As the number of phonemes increases in this way, it takes a lot of input time (usually 0.5 ~ 1 second delay time is needed to select one phoneme (consonant or vowel)). In Korean consonants, Bokja consonants, double vowels, double vowels, etc.), Korean expressions are often impaired.

An object of the present invention is to provide a Hangul input method and a communication terminal device for the Hangul syllable that can be input easily and quickly.

According to one aspect of the present invention, a Hangul input method and a communication terminal device therefor that can easily and quickly input consonants and vowels of Hangul are disclosed. According to the first embodiment of the present invention, the consonant key and the consonant information input through the activated consonant key in the Hangul input mode-In this case, the consonant information, the terminal to recognize the input consonant After inputting the consonant so that the user inputs additional information-check whether the consonant is a consonant, and if the input consonant is a consonant, the first key is switched to activate the vowel key, and the activated vowel key If is input, the second key is switched to activate the consonant key. According to the second embodiment of the present invention, the consonant key is activated in the Hangul input mode, the consonant inputted through the activated consonant key is recognized as an initial consonant and the first key is switched to activate the vowel key, and the activated vowel key is activated. The vowel and syllable composition information input through the syllable composition information-The syllable composition information is the Hangul composition information of the currently input syllable and the next syllable to be input, and is additionally input by the user after the vowel input. The consonant key is activated by maintaining the activated vowel key or switching the second key.

Here, the first key switch deactivates the consonant key activated upon confirming the initial input and activates the inactive vowel key, and the second key switch deactivates the activated vowel key upon confirming the neutral input and activates the inactive consonant key. It is to let.

In particular, the structure of the vowel key in the present invention, in the Korean input mode, eight short vowels ('ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ', 'ㅐ', 'ㅔ' ), Six double vowels ('ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', 'ㅒ', 'ㅖ'), seven double vowels ('ㅘ', 'ㅙ', 'ㅚ', 'ㅝ' A total of 21 neutral vowels including ',' ㅞ ',' ㅟ ',' ㅢ ') can be expressed as one phoneme without any combination of vowels.

According to the present invention, it is possible to shorten the input time of Hangul phonemes by reducing the number of inputs of Hangul phonemes, and to increase the efficiency of the entire Hangul input method by allowing easy and fast input of all Hangul syllables.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions will not be described in detail if they obscure the subject matter of the present invention.

1 is a diagram showing the configuration of a communication terminal to which the present invention can be applied.

The control unit 30 performs a function set in the communication terminal. In the present invention, the consonant soft key (Figs. 2A to 2J) or the vowel soft key (Figs. 3A to 3C), Alternatively, the consonant and vowel integration softkeys (FIG. 4A or 4B) are displayed to display the input result on the display unit 40 as the user touches a corresponding character (consonant and vowel in Korean). In addition, as the user presses the letters (consonants and vowels) displayed on the keypad 10, the display results on the display unit 40.

The keypad 10 is composed of a plurality of key buttons for inputting numbers and special characters or letters for a call, for example, in a mobile phone. In addition, a function button and a general button for storing, modifying, or importing the input text are further provided, and perform a function of a medium for transmitting a user's instruction to the controller 30. Of course, it is also possible to input text input from the touch screen unit 20 using the keypad 10, and input text input from the keypad 10 using the touch screen unit 20. Do. The object of the present invention may be a terminal having only the keypad 10, a terminal having only the touch screen unit 20, or a terminal having both the keypad 10 and the touch screen unit 20.

The touch screen unit 20 is an object-oriented text information input means. When the user applies a predetermined pressure to a character (consonant, vowel) on the upper surface of the panel by using a writing instrument such as a hand or a stylus pen, the character is required to recognize the corresponding character. Data, that is, touch screen data is generated and transmitted to the controller 30, and the controller 30 extracts character code data corresponding to the applied touch screen data from the memory unit 50 and combines the character code data to display the display unit ( 40). Soft keys of the touch screen unit 20 for text input will be described later. Since the character recognition and combination method through the touch screen unit 20 can be configured by applying a known technique, a detailed description thereof will be omitted.

The memory unit 50 stores a program for driving a function processed by the controller 30, a predetermined program for implementing convenience and basic functions of a user, and the like. For example, it is implemented as a volatile memory such as a RAM or a nonvolatile memory such as a flash memory, and a program that collectively controls the overall operation of the communication terminal or an operation program that processes data input from the keypad 10 or the touch screen unit 20. Etc. are stored. In particular, the memory unit 50 basically stores character information inputted and processed by the practice of the present invention, and has font data and character code data for a plurality of characters registered in advance.

The display unit 40 performs a display operation under the control of the controller 30, and the character information displayed on the display unit 40 is character information input through the keypad 10 or the touch screen unit 20. That is, when a user inputs a character, character code data corresponding to the character is extracted, font data is output together with the code data, and displayed on the display screen of the display unit 40.

In the Hangul input mode, the number of consonants of the Hangul can be expressed if the total number of consonants is 19. Therefore, the 14 consonants ('ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', 'ㅊ', 'ㅋ', 'ㅌ', 'ㄷ', 'ㅎ') and 5 consonants ('ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ') is enough. In addition, since the number of neutral vowels can be expressed in total of 21, these neutrals have 8 short vowels ('ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅣ', 'ㅐ', ' 이중 ') and 6 double vowels (' ㅑ ',' ㅕ ',' ㅛ ',' ㅠ ',' ㅒ ',' ㅖ '), 7 double vowels (' ㅘ ',' ㅙ ',' ㅚ ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅢ') are sufficient. In addition, since the total number of consonants is 27, it is possible to express 14 consonants, 5 consonants, and 11 consonants ('ㄳ', 'ㄵ', 'ㄶ', 'ㄺ', 'ㄻ', 'ㄼ'). , 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ', 'ㅄ').

The consonant softkey displayed on the touch screen unit 20 may be configured as shown in FIGS. 2A to 2J. 2a shows fourteen terminal sounds and five pairs of consonants ('ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ') and their terminal sounds ('a', 'c', 'ㅂ', ' 2 'is a consonant soft key separately configured for 14 terminal sounds and a pair of consonants. 2A and 2B show not only the terminal sound of Korean but also the consonant sound as one phoneme. In addition, as shown in FIG. 2C, not only 14 terminal sounds and 5 double consonants, but also 11 double consonants may be additionally allocated to the consonant softkey. Fig. 2C is regarded as one phoneme for not only the terminal sound and the double consonant of Korean but also the consonant sound. The consonant softkey may also have a 'collection' key that can be converted to a vowel softkey.

The consonant softkeys of FIGS. 2A to 2C show an example in which at least one consonant (one or two or three consonants are assigned to one button) is assigned to one button, but as shown in FIG. You can also assign one terminal tone and one twin to each button. 2D considers not only the terminal sound of Korean but also the consonant as one phoneme. Also, as shown in FIGS. 2E to 2G, one terminal sound, a double consonant, and a double consonant sound may be allocated to one button. 2E to 2G are regarded as one phoneme for not only the terminal sound and the double consonant of Korean, but also the consonant sound. At this time, the number of buttons should be 31 (14 terminal tone keys, 5 double consonant keys, 11 double consonant keys, and 1 vowel key). In FIG. 2E and FIG. 2F, fourteen terminal sounds and five pairs of consonants are embodied in a one-to-one button manner on the left side and eleven double consonants are embodied in a one-to-one button method on the right side. The one-to-one button method is implemented, and eleven consonants are implemented by one-to-one button method on the lower side. In Figs. 2E to 2G, an identification (eg, 'thick lines') may be given to the boundary portion so as to easily distinguish between terminal sounds and double consonants that can be used for both initial and final sounds, and a double consonant used only for final sounds.

The vowel softkey displayed on the touch screen unit 20 may be configured as shown in FIGS. 3A to 3C. Normal short vowels (eg 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅡ', 'ㅑ') or basic double vowels (eg 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ' ), Even if you combine vowels (heavenly), or complete a single vowel or double vowel with a single keystroke, a single vowel of "의", "ㅔ", or a double vowel of "ㅒ", "ㅖ", or For the vowels of "ㅘ", "ㅙ", "ㅚ", "ㅝ", "ㅞ", "ㅟ" and "ㅢ", a combination of vowels is required. However, in the present invention, as shown in Figs. 3a and 3b, a total of 21 neutral vowels used in Hangul are represented on the vowel softkey, so that all the vowels can be expressed by one key input. 3A and 3B show not only the short vowels of Hangul but also the double vowels and the double vowels as one phoneme. The vowel softkey may also have a 'consonant' key that can be converted to a consonant softkey.

Although the vowel softkey of FIG. 3A shows an example in which at least one vowel (one or two vowels are assigned to one button) is assigned to one button, one short vowel is assigned to one button, as shown in FIG. 3B. You can also assign one double vowel and one double vowel. FIG. 3C shows a consonant (eg, 'a') input as a consonant on the vowel softkey of FIG. 3A. In addition, although not shown in the drawing, a method of showing consonants inputted as initials together in the vowel softkey of FIG. 3B may also be possible.

Therefore, according to Fig. 2a (or Fig. 2b or 2d) and Fig. 3a (or Fig. 3b or Fig. 3c), all syllables of Hangeul except for Bokjaum (ie, no support) or three (ie support) (When there is a finality), the phoneme can be configured. Examples of phonemes to be input according to FIGS. 2A (or 2B or 2D) and 3A (or 3B or 3C) are shown in Table 1 below.

word Initiality neutrality Jongseong Phoneme count you N ㅓ 2 River A A ㅇ 3 king ㅇ ㅘ ㅇ 3 chicken C A ㄺ 4 Whack ㄲ ㅘ ㅇ 3

According to Fig. 2c (or Fig. 2e or Fig. 2f or Fig. 2g) and Fig. 3a (or Fig. 3b or Fig. 3c), all syllables of Hangul including a consonant can be composed of two or three phonemes. Examples of phonemes to be input according to FIGS. 2c (or 2e or 2f or 2g) and 3a (or 3b or 3c) are shown in Table 2 below.

word Initiality neutrality Jongseong Phoneme count you N ㅓ 2 River A A ㅇ 3 king ㅇ ㅘ ㅇ 3 chicken C A ㄺ 3 Whack ㄲ ㅘ ㅇ 3

In one embodiment, the phoneme candidate group (consonant softkey or vowel softkey) is totally 3 horizontally and 4 vertically without page switching in consideration of the screen size as shown in FIGS. 2A to 2C, 3A, and 3C. 12 can be configured. In this case, two or three phonemes (consonants or vowels) are assigned to one key. It should be noted that the same effect can be obtained even if the phoneme candidate group is composed of four horizontally and three vertically, and various variations (4 × 4, 3 × 5, 5 × 3, etc.) are possible.

In another embodiment, the phoneme candidate group (consonant softkey or vowel softkey) assigns one phoneme (consonant or vowel) to one key as shown in Figs. 2D to 2G and 3B, with a page switching key separately. can do.

In another embodiment, candidate groups of phonemes (consonant softkeys or vowel softkeys) as shown in FIGS. 2D-2G and 3B may assign one phoneme (consonant or vowel) to one key without page switching. have. In this case, all consonants or vowels may not be displayed in view of the screen size, and thus, it may be desirable to scroll the screen up and down or left and right by moving the screen up and down.

As an example according to the first embodiment of the present invention, when two to three phonemes are assigned to one key, pressing the corresponding key once selects the first consonant (or vowel), and pressing two times in succession The third consonant (or vowel) is selected, and three consecutive presses select the third consonant (or vowel). For example, in the consonant softkey of any one of Figs. 2A to 2G, when entering “ac” as a consonant, touch it with a finger or a stylus pen, and then lightly drag it up (or down). Or drag to the left soft key or to the right soft key to switch to the Vowel softkey. In addition, in the case of inputting "ㄲ" as the initial consonant in the consonant softkey of FIG. 2A, the touch bar can be touched twice with a finger or a stylus pen in succession, and then dragged up / down / left / right or switched to a vowel softkey. 'Key.

In the first embodiment of the present invention, each of the consonants and vowels of the Hangul is configured to configure each softkey, and in the text input mode (strictly, the Hangul input mode) through the softkey, the controller 30 first consonants. By displaying the soft key on the touch screen unit 20, when the user's initial entry is input, the vowel soft key is automatically switched to the touch screen unit 20 and displayed. When the vowel is input, the consonant soft key is displayed again on the touch screen unit 20. ) To automatically switch. If there is no support (jongjong) and there is a support (jongjong), the two characters may be combined in the case of the Bongja consonant even if there is a support (jongjong) because of the characteristics of Hangul (Figs. 2c and 2e to 2g, 2A, 2B and 2D do not support double consonants), if the initial input is not confirmed, the vowel softkey is not activated (not automatically switched and displayed). If consonants are entered with the consonant softkey enabled, letters are formed (recognized as the final syllables), and consonants are listed insignificantly if no consonant input is confirmed for subsequent consonants.

In this case, when the initial input is performed, the user touches a specific phoneme (consonant) key (for example, 'ㄱ') on one of the consonant softkeys of FIGS. Touch the 'collection' key to give a small move to or switch to the Vowel softkey. Then, the controller 30 detects the up / down / left / right movement or vowel key touch, confirms the initial input, and then deactivates the consonant softkey (disappears from the touch screen unit 20). One vowel softkey is activated and displayed on the touch screen unit 20. However, if the initial input is not confirmed, the current consonant soft key is maintained on the touch screen unit 20. In addition, when the vowel input is confirmed, the control unit 30 deactivates the vowel softkey (disappears from the touch screen unit 20), and activates the consonant softkey of any one of FIGS. 2A to 2G and displays it on the touch screen unit 20. do. That is, if the initial input is confirmed in any of the currently activated consonant softkeys of Figs. 2A-2G, the consonant softkey is automatically switched to the vowel softkey, and the vowel softkey of any of the currently activated Figs. 3A-3C. Switches the Vowel softkey to the Consonant softkey when is confirmed, but keeps the state of the active consonant softkey in the active consonant softkey if it is not confirmed (ie, there may be a consonant input after the final input). do. If the consonant input is confirmed and the consonant softkey is automatically switched to the vowel softkey, the consonant softkey is activated again if you delete the incorrectly entered consonant. In addition, when the vowel (neutral) input is confirmed and the vowel softkey is automatically switched to the consonant softkey, the vowel softkey is activated again when the erroneous input neutral is deleted. In addition, when a button input corresponding to a next function such as SPACE is made during Korean input, the cursor moves to the right side, and activates the consonant softkey of any one of FIGS. 2A to 2G.

In the first embodiment, a pre-input (eg, a) may be displayed together with the vowel softkey automatically activated after the initial input is detected as shown in FIG. 3C. At this time, only the letters that can form the correct syllable can be activated by the Hangul software. Although the previously entered initiality is marked with "a" in the drawing, hereinafter, FIG. 3C will be described as an optional initial initiality together displayed on a vowel softkey.

Looking at the Hangul input method based on the consonant and vowel softkeys according to the first embodiment of the present invention.

Looking at the process of inputting the actual character "Sejong the Great" using the consonant / vowel softkey displayed on the touch screen 20, first, in order to enter the "three", the terminal in the character input mode (of course, the character input mode In order to be switched, there may be a method of selecting a specific button on the keypad 10 of the terminal and a method of selecting a menu displayed on the touch screen unit 20, but the above-mentioned two methods generate the same result). do. When the terminal proceeds to the Hangul input mode of the character input mode, any consonant soft key of FIGS. 2A to 2G is activated and displayed on the touch screen unit 20.

First, in the consonant softkey of any one of FIGS. 2A to 2G, after the user touches “”, the user may make a small movement to “up” or “down” or “left” or “right” or switch to the vowel softkey. When the user presses the 'collection' key, the terminal recognizes the input "s" as an initial consonant and activates any one of the vowel softkeys of FIGS. 3a to 3c and displays it on the touch screen unit 20. When the user touches "ㅔ" in any one of the vowel softkeys of FIGS. 3a to 3c, the terminal checks the vowel input and activates the consonant softkey of any one of FIGS. 2a to 2g to the touch screen unit 20. Display. At this time, the letter "three" is recognized and displayed on the display unit 40.

Here, the user enters the consonants and recognizes that the terminal is consonant (up / down / left / right movement or mode switch key), but after the vowel input, the terminal automatically uses the consonant softkey even if there is no user action. It is activated and displayed on the touch screen unit 20.

Then, in the consonant softkey of any one of Figs. 2A to 2G, after the user touches "", the user may make a small movement to 'up' or 'down' or 'left' or 'right' or switch to the vowel softkey. When the user touches the 'collection' key, the terminal recognizes the input “” as an initial consonant and activates the vowel softkey of FIGS. 3A to 3C to display it on the touch screen unit 20. When the user touches "ㅗ" in any one of the vowel softkeys of FIGS. 3a to 3c, the terminal checks the vowel input and activates the consonant softkey of any one of FIGS. 2a to 2g to the touch screen unit 20. Display. After the user touches "o" in any of the consonant softkeys in FIGS. 2a-2g, the user may not move the vowel softkey with little movement to the 'up' or 'down' or 'left' or 'right'. If the 'vowel' key is not touched, the terminal recognizes the input "o" as a finality and maintains the currently activated consonant softkey on the touch screen unit 20 as it is. At this time, the character "Sejong" is recognized and displayed on the display unit 40.

Next, after the user touches "c" while the consonant softkey of any one of FIGS. 2a to 2g is maintained, the user moves or collects a small movement toward 'up' or 'down' or 'left' or 'right'. Touching the 'collection' key, which can be switched to a softkey, the terminal recognizes the input "c" as the initial consonant and activates the vowel softkey of FIGS. 3a to 3c and displays it on the touch screen unit 20. . When the user touches "ㅐ" in any one of the vowel softkeys of FIGS. 3a to 3c, the terminal checks the vowel input and activates the consonant softkey of any one of FIGS. 2a to 2g to the touch screen unit 20. Display. At this time, the character "Sejongdae" is recognized and displayed on the display unit 40.

Subsequently, in the consonant softkey of any of FIGS. 2A-2G, the user may touch “o” and then move the vowel softkey with a small movement to “up” or “down” or “left” or “right”. When the user touches the "collection" key, the terminal recognizes the input "o" as an initial consonant and activates the vowel softkey of FIGS. 3a to 3c and displays it on the touch screen unit 20. When the user touches "ㅘ" in any one of the vowel softkeys of FIGS. 3a to 3c, the terminal checks the vowel input and activates the consonant softkey of any one of FIGS. 2a to 2g to the touch screen unit 20. Display. Then, when the user touches "o" in any of the consonant softkeys of FIGS. 2a to 2g, the character "Sejong the Great" is recognized and displayed on the display unit 40. Thereafter, the user may click or touch an input confirmation button to complete text input.

In the above state, when the consonant input is confirmed and the consonant softkey of any one of Figs. 2A to 2G is automatically switched to the vowel softkey of any one of Figs. The consonant softkey of any of Figs. 2G is activated, and the vowel (neutral) input is confirmed, and the vowel softkey of any of Figs. 3A to 3C is automatically switched to the consonant softkey of any of Figs. 2A to 2G. In the state, when the typo entered neutral is deleted, the vowel softkey of FIGS. 3A to 3C is activated again.

In the second embodiment of the present invention, each of the consonants and vowels of the Hangul is configured to configure each softkey, and in the text input mode (strictly, the Hangul input mode) through the softkey, the controller 30 first consonants. By displaying the soft key on the touch screen unit 20, when the initial consonant (consonant) is input from the user, the vowel soft key is automatically switched to the touch screen unit 20 and displayed. In this case, when the vowel (neutral) is input, the vowel input method Depending on the vowel softkeys (e.g. for Hangul input with no corresponding syllables and the consonant of the next syllable consisting of a specific consonant (eg 'ㅇ')), the consonant softkeys are automatically To display by switching (for example, Hangul input consisting of a terminal sound or a double consonant support even if the syllable has no support or a support), or the Bokjaja softkey is automatically switched to the touch screen unit 20 And (e. G. The base of the corresponding syllable for Hangul input configured to bokjaeum). If there is no support (Jongsung) due to the characteristics of Hangul, and there is a support (when Jongsung consists of terminal or double consonants), if there is no support, the first syllable of the next syllable is a certain consonant (for example 'ㅇ'), In the case of double consonants, the two may be combined, so activate the appropriate softkey according to the vowel (neutral) input method.

In the initial input, the user may use the consonant softkey of any one of FIGS. 2A to 2G (or the consonant only corresponds to the final consonant), so that the consonant softkey of the terminal sound and the double consonant except for the consonant sound as shown in FIGS. 2A, 2B, and 2D. It is only required to touch the phoneme (consonant) key (for example, 'a') in the above method (in contrast to the first embodiment, the user does not need to perform an action that the terminal can recognize as first). Then, after confirming the initial input, the control unit 30 deactivates the consonant softkey (disappears from the touch screen unit 20) and activates the vowel softkey of FIGS. 3A to 3C to the touch screen unit 20. Display. In particular, when the vowel input is confirmed (eg, 'ㅏ'), the controller 30 maintains the currently activated vowel softkey on the touch screen unit 20 according to the vowel input method, or deactivates the vowel softkey (touch screen). 2a to 2g to activate the consonant softkey of any one of Figs. 2a to 2g to display it on the touchscreen unit 20, or to disable the vowel softkey (disappears from the touchscreen unit 20). 2J to activate the soft consonant softkey of any one of the display on the touch screen (20). In the vowel input method, a small movement is made to 'up' or 'down' or 'left' or 'right' while the vowel key (for example, 'ㅏ') is touched. That is, if consonant input is confirmed on the currently active consonant softkey, the consonant softkey is automatically switched to the vowel softkey; when vowel input is confirmed on the currently active vowel softkey, the current vowel softkey is retained according to the vowel input method. Or switch to the Consonant softkey. If the consonant input is confirmed and the consonant softkey is automatically switched to the vowel softkey, the consonant softkey is activated again if you delete the incorrectly entered consonant. In addition, if the vowel (neutral) input is confirmed and the vowel softkey is maintained or the vowel softkey is automatically switched to the consonant softkey, the vowel softkey is activated again by deleting the mistyped neutral. In addition, when a button input corresponding to a next function such as SPACE is made during Korean input, the cursor moves to the right side, and activates the consonant softkey of any one of FIGS. 2A to 2G.

In the second embodiment of the present invention, when the consonant softkey is automatically switched to the vowel softkey, the current vowel softkey can be maintained or switched to the consonant softkey according to the vowel input method. The reason for the differentiation is that the Hangul syllable of the current Hangul syllable has no support (finality) and the consonant of the next syllable is composed of a specific consonant (for example, 'ㅇ') (Example 2-1), or the Hangul Syllable currently being input This case is composed only of a consonant and a neutral without the support (finality) (Example 2-2), or the support (finality) of the Hangul syllable to be input currently consists of a terminal sound or a double consonant sound. For example, the Hangul syllables to be input currently (jongseong) is due to a variety of Hangul constitution as in the case of the consonant consonants (Example 2-4). Embodiments 2-3 and 2-4 assume that the consonant is composed of a separate consonant softkey. Accordingly, when the consonant softkey of any one of FIGS. 2C, 2E, and 2G is configured together with a terminal sound, a consonant sound, and a consonant sound, the distinction between the second embodiment and the second embodiment may be meaningless. In the following description, both will be described separately.

According to the embodiment 2-1, when the consonant is input in the Hangul input mode, the controller 30 deactivates the consonant softkey (disappears from the touch screen unit 20) and the vowel soft of any one of FIGS. 3A to 3C. The key is activated and displayed on the touch screen unit 20. Thereafter, when the user touches a vowel key (for example, 'ㅏ') on any one of the vowel softkeys of FIGS. 3A to 3C and makes a small movement toward 'up', the controller 30 moves to 'up'. While detecting and displaying the touched vowel on the display unit 40 and the initial syllable of the next syllable is not input, the initial consonant of the next syllable is considered to be input (for example, 'ㅇ') and the predetermined first consonant is displayed. ). Therefore, since the initial entry was automatically input, the current vowel softkey is maintained (activated) in the touch screen unit 20 as it is. Embodiment 2-1 is useful when inputting one syllable of a Hangul composed of only a consonant and a neutral without a support, and then inputting a Hangul composed of a specific consonant (for example, 'ㅇ') after the consonant of the next syllable. do.

According to the embodiment 2-2, when the consonant is input in the Hangul input mode, the controller 30 deactivates the consonant softkey (disappears from the touch screen unit 20) and the vowel soft of any one of FIGS. 3A to 3C. The key is activated and displayed on the touch screen unit 20. Thereafter, when the user touches a vowel key (for example, 'ㅏ') in any one of the vowel softkeys of FIGS. 3A to 3C and gives a small movement to the lower side, for example, the controller 30 detects the downward movement. The touched vowel is displayed on the display unit 40 as being input, and the current vowel softkey is deactivated, and the consonant softkey of any one of FIGS. The terminal sound, which can be a consonant soft key of a double consonant except for a consonant sound as in any one of FIG. 2D) is activated and displayed on the touch screen unit 20. At this time, if an initial consonant is input from the consonant softkey, the current consonant softkey is deactivated (disappears from the touch screen unit 20) and the vowel softkey of FIGS. 3A to 3C is activated to the touch screen unit 20. Display. Embodiment 2-2 is useful when inputting a Hangul composed of only the initial and the neutral without the support (finality). The difference from the embodiment 2-1 is when the consonant of the next syllable is not a specific consonant (for example, ㅇ).

According to the embodiment 2-3, when the consonant is input in the Hangul input mode, the controller 30 deactivates the consonant softkey (disappears from the touch screen unit 20), and the vowel soft of any one of FIGS. 3A to 3C. The key is activated and displayed on the touch screen unit 20. Thereafter, when the user touches a vowel key (for example, 'ㅏ') in any one of the vowel softkeys of FIGS. 3A to 3C and gives a small movement to the 'left', the controller 30 detects the movement to the 'left'. The touched vowel is displayed on the display unit 40 as being input, and the current vowel softkey is deactivated, and the consonant softkey of any one of FIGS. The terminal sound, which can be a consonant soft key of a double consonant except for a consonant sound as in any one of FIG. 2D) is activated and displayed on the touch screen unit 20. At this time, the two consonants and the consonant consonants must be continuously inputted in the consonant softkey to deactivate the current consonant softkey (disappears from the touch screen unit 20), and activate the vowel softkey in FIGS. 3A to 3C. It is displayed on the screen part 20. That is, after the final syllable of the current syllable and the first syllable of the next syllable are continuously input, the consonant softkey is switched to the vowel softkey. The second embodiment is useful when inputting a Hangul composed of a consonant, a neutral, and a terminal or double consonant.

According to the embodiment 2-4, when the consonant is input in the Hangul input mode, the controller 30 deactivates the consonant softkey (disappears from the touch screen unit 20) and the vowel soft of any one of FIGS. 3A to 3C. The key is activated and displayed on the touch screen unit 20. Thereafter, when the user touches a vowel key (for example, 'ㅏ') on any one of the vowel softkeys of FIGS. 3A to 3C and gives a small movement to 'right', for example, the controller 30 detects a movement to 'right'. The touched vowel is displayed on the display unit 40 as being inputted, the current vowel softkey is deactivated, and the vowel softkey of any one of FIGS. 2H to 2J is activated and displayed on the touch screen unit 20. In this case, when the final consonant is input in the consonant softkey, the current consonant softkey is deactivated, and the consonant softkey of any one of FIGS. 2A to 2G (or the consonant only corresponds to the final consonant), such as any one of FIGS. 2A, 2B, and 2D. Terminal sound, except for the consonant consonant, can be a consonant soft key of the consonant) to activate the display on the touch screen (20). Then, when the consonant is input from the consonant softkey, the controller 30 deactivates the current consonant softkey (disappears from the touch screen unit 20) and activates the vowel softkey of FIGS. 3A to 3C. (20). Embodiment 2-4 is useful when inputting a Hangul composed of the initial, neutral, and final consonants.

In the above-described embodiments 2-1 to 2-4, the previously inputted constellation (eg, a) may be displayed on the vowel softkey activated after the initial consonant is input as shown in FIG. 3C.

In addition, in the embodiment 2-4, the first consonant and the neutral of the previous syllable may be displayed together on the compound consonant soft key as shown in FIG. 2I. At this time, the user's perception is activated by activating only the letters (for example, 'chicken', 'similar', 'worn', etc.) that can constitute correct syllables by the Hangul software without displaying all meaningless Hangul syllables. It is easy to increase convenience and to induce proper use of Hangul.

Looking at the Hangul input method based on the consonant and vowel softkeys according to the second embodiment of the present invention.

Looking at the process of inputting the actual character "Sejong the Great" using the consonant / vowel softkey displayed on the touch screen 20, first, in order to enter the "three", the terminal in the character input mode (of course, the character input mode In order to be switched, there may be a method of selecting a specific button on the keypad 10 of the terminal and a method of selecting a menu displayed on the touch screen unit 20, but the above-mentioned two methods generate the same result). do. When the terminal proceeds to the Hangul input mode of the character input mode, any consonant softkey (or the consonant only corresponds to the final consonant of any one of Figs. 2a to 2g, except for the consonant sound like any one of Figs. , Which may be a consonant softkey of a double consonant) is activated and displayed on the touch screen unit 20.

First, when the user touches "s" on any one of the consonant softkeys of FIGS. 2a, 2b, and 2d, the terminal recognizes the input "s" as initial, and the vowel soft of any of FIGS. The key is activated and displayed on the touch screen unit 20. In the activated vowel softkey, when the user touches "ㅔ" and makes a small movement to "down" according to the embodiment 2-2, the terminal checks the vowel input and selects any one of FIGS. 2A, 2B, and 2D. One consonant softkey is activated and displayed on the touch screen unit 20. At this time, the letter "three" is recognized and displayed on the display unit 40.

Here, when the user inputs a vowel (neutral), the terminal recognizes that the current syllable input is a syllable composed of initial + neutral syllables (lower movement). Therefore, the terminal recognizes the consonant to be input as a consonant of the next syllable and immediately switches to the vowel softkey when the consonant is input.

That is, when the user touches the "Y" in the consonant softkey of any one of FIGS. 2A, 2B, and 2D, the terminal recognizes the input "Y" as the initial consonant and immediately selects the vowel soft of any one of FIGS. 3A-3C. The key is activated and displayed on the touch screen unit 20. In the activated vowel softkey, when the user touches "ㅗ" and makes a small movement to the "left" according to the embodiment 2-3, the terminal checks the vowel input and selects any one of FIGS. 2A, 2B, and 2D. One consonant softkey is activated and displayed on the touch screen unit 20.

Here, when the user inputs the vowel (neutral), the terminal recognizes that the current syllable input is a syllable composed of initial + neutral + final (including syllables and twin consonants) (left movement). Accordingly, the terminal recognizes the consonant input afterward as the final consonant and the next input consonant as the first consonant of the next syllable, and then converts the consonants into vowel softkeys.

That is, when the user touches "o" in any one of the consonant softkeys of FIGS. 2a, 2b and 2d, the terminal recognizes the input "o" as a finality and uses the currently activated consonant softkey in the touch screen unit ( 20) as it is. At this time, the character "Sejong" is recognized and displayed on the display unit 40. Also, when the user touches "c" while the consonant softkey of any one of FIGS. 2a, 2b, and 2d is maintained, the terminal recognizes the input "c" as a consonant and finally does not recognize any of FIGS. 3a to 3c. One vowel softkey is activated and displayed on the touch screen unit 20. In the Vowel softkey of any one of Figs. 3a to 3c, if the user touches "ㅐ" and makes a small movement to "up" according to the embodiment 2-1 above, the terminal confirms the vowel input and the current vowel. Keep the softkey.

Here, when the user inputs a vowel (neutral), the user may recognize that the terminal currently inputs a syllable composed of a consonant (for example, 'ㅇ') and a syllable composed of a consonant (eg, 'ㅇ'). Movement). Therefore, even if the first syllable of the next syllable is not input, the terminal regards the first syllable of the next syllable (for example, 'ㅇ') and automatically displays the corresponding first consonant on the display unit 40, and displays the currently activated vowel softkey on the touch screen. It keeps to the part 20 as it is. At this time, the character "Sejongdae o" is displayed on the display unit 40.

Then, when the user touches "ㅘ" according to the embodiment 2-3 in the vowel softkey of any one of FIGS. 3A to 3C and makes a small movement to the "left", the terminal confirms the vowel input and FIG. 2A. 2B and 2D, the consonant softkey is activated and displayed on the touch screen unit 20. FIG.

Here, when the user inputs the vowel (neutral), the terminal recognizes that the current syllable input is a syllable composed of initial + neutral + final (including syllables and twin consonants) (left movement). Therefore, the terminal recognizes the consonant input later.

Accordingly, when the user touches "o" in any one of the consonant softkeys of FIGS. 2a, 2b and 2d, the character "Sejong the Great" is recognized and displayed on the display unit 40. Thereafter, the user may click or touch an input confirmation button to complete text input.

Another method of Hangul input based on the consonant and vowel softkeys according to the second embodiment of the present invention is as follows.

For example, in the case of inputting the letter "Next", when the user touches "c" on any of the consonant softkeys of FIGS. 2a, 2b and 2d, the terminal recognizes the input "c" as the initial consonant. 3A to 3C, the vowel softkey is activated and displayed on the touch screen unit 20. In the vowel softkey of any one of FIGS. 3A to 3C, when the user touches "ㅏ" and makes a small movement to "up" according to the embodiment 2-1, the terminal does not have to enter the next syllable first syllable. The first syllable of the next syllable (eg, 'o') is regarded as input, and the first syllable is automatically displayed on the display unit 40, and the currently activated vowel softkey is maintained on the touch screen unit 20 as it is. At this time, the letter "da" is displayed on the display unit 40.

Thereafter, when the user touches "-" in the vowel softkey of any one of FIGS. 3A to 3C and makes a small movement to the left side, according to the embodiment 2-3, the terminal checks the vowel input and FIG. 2A. 2B and 2D, the consonant softkey is activated and displayed on the touch screen unit 20. FIG. Then, when the user touches the "k" in the activated consonant softkey, the terminal recognizes the input "k" as the terminal and maintains the current activated consonant softkey in the touch screen unit 20 as it is. At this time, the character "next" is recognized and displayed on the display unit 40. In addition, when the user touches "o" while the consonant softkey of any one of FIGS. 2a, 2b and 2d is maintained, the terminal recognizes the input "o" as a consonant and selects any one of FIGS. 3a to 3c. Activate the vowel softkey of the display on the touch screen unit 20. In the activated vowel softkey, when the user touches "ㅔ" and makes a small movement to "down" according to the embodiment 2-2, the text "Next" is recognized and displayed on the display unit 40. Thereafter, the user may click or touch an input confirmation button to complete text input.

As another example, in the case of inputting the letter "chicken porridge", when the user touches "c" on any one of the consonant softkeys of FIGS. 2a, 2b, and 2d, the terminal recognizes the input "c" as an initial consonant. The vowel softkey of any one of FIGS. 3A to 3C is activated and displayed on the touch screen unit 20. In the vowel softkey of any one of FIGS. 3A to 3C, when the user touches "ㅏ" and makes a small movement to "right" according to the embodiment 2-4, the terminal deactivates the current vowel softkey. 2H to 2J activate the soft consonant soft key of any one and display it on the touch screen unit 20. In this case, as shown in FIG. 2H, only the consonant softkey may be displayed, or the entire consonant softkey including the previous consonant and the vowel may be displayed, and as shown in FIG. 2J, a letter (for example, ' 'Chicken', 'like', 'worn', etc.) can be activated and displayed.

When the final consonant of the consonant is input, the terminal recognizes the input "ㄺ" as the finality, deactivates the currently activated double consonant softkey, and presses the consonant softkey of any one of FIGS. 2A, 2B, and 2D to the touch screen unit 20. To be activated). At this time, the letter "chicken" is recognized and displayed on the display unit 40.

Subsequently, when the user touches the "Y" in the consonant softkey of any one of FIGS. 2A, 2B, and 2D, the terminal recognizes the input "Y" as an initial consonant and selects the vowel soft of any one of FIGS. 3A-3C. The key is activated and displayed on the touch screen unit 20. In the activated vowel softkey, after touching "TT" according to the embodiment 2-3 and making a small movement to the "left", the terminal checks the vowel input and selects one of FIGS. 2A, 2B, and 2D. The consonant softkey is activated and displayed on the touch screen unit 20. When the user touches "a" in the activated consonant softkey, the terminal recognizes the input "a" as the finality and displays the character "chicken porridge" on the display unit 40. Thereafter, the user may click or touch an input confirmation button to complete text input.

In the above first and second embodiments, when two or more consonants or vowels are assigned to one softkey button, one consonant or vowel is completed and the consonants or vowels assigned to the same button must be input again. If you need to do this, you need to press the button once or twice in succession to select consonants or vowels. You can enter it accordingly. For example, if a button has two consonants, "a" and "ㄲ", enter "a" and then enter "a" again. (E.g., 0.3 seconds), when "ㄲ" is pressed again, "a" and "ㄲ" are recognized as selected. This lead time interval is a time required for any phoneme selected by the user to be recognized as an input, and can be arbitrarily adjusted according to the user's key pressing skill.

The lead time interval is also useful for having one consonant or vowel complete when one softkey button is assigned two or more consonants or vowels. For example, if a button has two vowels, “ㅏ” and “ㅑ”, you can press once to enter “ㅏ” and two times to enter “ㅑ”. After the lead time interval (for example 0.3 seconds) has elapsed after pressing "or", "the vowel is recognized as selected. The same can be applied to consonants.

Meanwhile, the consonant and vowel softkeys may be implemented on the keypad 10. For example, as shown in FIG. 5, FIG. 2A and FIG. 3A are simultaneously implemented as hard keys on the keypad 10. For example, assign "a", "ㄲ", "ㅔ", and "ㅖ" to the first key. In character input mode (Hangul input mode) through hard keys, consonant keys are activated first. When the consonant key is active, press the 1 key once to enter the "" ", twice press" ㄲ ". After inputting the consonant, the user presses a mode switch key ('#' key) to activate the vowel key. After the vowel input, the user presses the mode switch key ('#' key) to activate the consonant key. When the vowel key is activated, pressing the 1 key once inputs "ㅔ", and pressing the key twice enters "ㅖ". Hangul input based on such hard keys can be performed similarly to the Hangul input method using soft keys. Requires user input.

Meanwhile, the consonant and vowel softkeys may also be configured on the touch screen 20 as shown in FIGS. 4A and 4B. Fig. 4A is a combination of the consonant softkey of Fig. 2A and the vowel softkey of Fig. 3A, and Fig. 4B is a combination of the consonant softkey of Fig. 2B and the vowel softkey of Fig. 3A. In this case, however, no mode switching key ('vowel' key or 'consonant' key) can be switched to the consonant or vowel softkey. Although not shown in the figures, it is also possible to configure the consonant softkey of FIG. 2A or FIG. 2B together with the vowel softkey of FIG. 3B and the consonant softkey of any of FIGS. 2C-2G and FIG. 3A or 3B. It is also possible to configure a vowel softkey together.

Although the method has been described through specific embodiments, the method may also be embodied as computer readable code on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the above embodiments can be easily deduced by programmers of the present invention.
