Description

Method of inputting Hangul characters and its input device {Method and Apparatus of Inputting Han Gul Character}

The present invention relates to a method of inputting Hangul characters and its input device, and more particularly, to reduce consonant collisions by arranging all consonants except the consonant consonants, and to recognize syllables by recognizing stepwise drag directions on a touch screen when inputting vowels. The present invention relates to a Hangul character input method and an input device capable of reducing the number of input strokes of a vowel, providing the convenience of input, and improving the input speed well.

Conventionally, there are a number of ways of inputting Hangul through various information communication terminals such as mobile communication terminals, PDAs, personal computers or navigation. As a software keyboard applied to a mobile communication terminal for Korean input, a software keyboard having a QWERTY type keyboard layout is common. However, the screen is too small to display the entire keyboard, which inconveniences the user. Although only some keyboards are displayed and the user presses a special key, a method of displaying the remaining keyboards is adopted. However, there is still an inconvenience of having to input several keys in inputting Korean characters.

Other software keyboards applied to information communication terminals for Hangul input include a software keyboard having a keyboard layout of the heaven and earth style and a keyboard layout of the naragle style.

First, the vowel input in the Cheonjiin method is a method of completing vowels forming syllables by combining 'ㅣ', '·' and '-'. Consonant input in the Cheonjiin method requires the input of a delimiter to avoid consonant collisions, and when the vowel input has to be input for each stroke, the number of inputs is increased. If such consonants are not continuous input, it is inconvenient to input the separation signal by pressing the direction key or wait for a certain time to input the first syllable consonant.

Next, in the narrative method, the basic vowel 'ㅏ', 'ㅓ', 'ㅗ', 'TT' and 'ㅡ' are placed on one key when entering the vowel, and the '*' key and the '#' key are used to divide the sound and the sound Make a consonant and add a stroke to the consonants 'AB', 'B', 'B', '', ','. Although the input method has a relatively small number of strokes, the learning time is relatively long because there are not many consonants in the keyboard, and the fingering distance is long by using '*' and '#' keys frequently.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to place all the consonants except the consonant consonants on the touch screen to reduce the consonant collision when inputting consonants and its consonant To provide an input device.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, embodiments of the present invention illustrated below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

1A is a schematic flowchart of a Hangul character input method according to an embodiment of the present invention, FIG. 1B is an exemplary view showing a Hangul character input method on a touch screen according to the embodiment of FIG. 1A, and FIG. 1C is A specific example of Hangul input using the Hangul character input method illustrated in FIG. 1B is shown.

First, a user input is waited through the touch screen (110).

Thereafter, it is determined whether one consonant of one of the consonant regions displayed on the touch screen by the user input is in a continuous contact state for a predetermined time (120).

Then, if one consonant is in a continuous contact state, the basic vowel centered on the consonants in contact state, in this embodiment 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or 'ㅡ' Display substantially radially (130). Here, the basic vowels displayed radially are preferably arranged at a predetermined position. The arrangement of the basic vowels will be described later with reference to FIG. 1B. Here, if one consonant is not in a continuous connection state, it is determined whether a double click is detected in one consonant on the touch screen (125). Then, when a double click is detected on one consonant, it is determined whether the contact state is continuous for a predetermined time after the double click (127). Meanwhile, in the double click detection determination step 125, if the double click is not detected, the consonant first touched on the touch screen is displayed (180). In addition, when a double click is detected on one consonant, the sound of the consonant is displayed. Then, if the state of continuous contact after double-click (125 127), the basic vowel around the consonants of the sound in contact, in the present embodiment 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or Display '-' substantially radially (130). Here, the basic vowels displayed radially are preferably arranged at a constant position. On the other hand, in the continuous contact state determination step after the double click (127), if it is not the continuous contact state, only the consonants double-clicked on the touch screen is displayed (180).

Thereafter, a first continuous drag from the first contacted consonant 120 or the double clicked consonants 125 and 127 to a radially displayed basic vowel about the consonant is detected (140).

Thereafter, after the first drag is detected, it is determined whether the contact is continuously made on the touch screen for a predetermined time (150). On the other hand, if the direction of the first drag detected is not the preset drag direction, that is, if the first drag is detected in a direction other than the direction of the default bar arranged radially, the input of the default bar is released. Only consonants without vowels are displayed on the touch screen (145, 180). In addition, if there is no continuous contact on the touch screen for a predetermined time, the syllables composed of consonants and basic vowels located in the first drag direction are displayed (150, 170).

Then, if the touch screen is continuously in contact for a predetermined time (150,130), the second drag direction to one of the radially displayed basic vowels around the consonant or the consonant is detected and an additional vowel derived from the basic vowel is detected. It forms (130, 140, 150 steps repeat). That is, it is determined whether the number of drags is three times by counting the number of drags on the touch screen (160). If the number of drags is not three, the second drag direction is detected to form additional collections. Here, additional vowels derived from the default vowel can be 'ㅐ', 'ㅑ', 'ㅔ', 'ㅕ', 'ㅘ', 'ㅚ', 'ㅛ', 'ㅝ', 'ㅟ', 'ㅠ' or Contains 'ㅢ'.

Thereafter, one syllable by the additional vowel is displayed through the touch screen (180).

Subsequently, after detecting a second drag and a drag direction to one of the basic vowels displayed radially around the consonant or consonant (140), the dragged vowel displayed on the touch screen is continuously It is determined whether the contact (150). On the other hand, if the detected second drag direction is not a preset drag direction, i.e., if a second drag is detected in a direction other than the default vowel direction disposed at a radial position, the input of the additional vowel is released. One syllable consisting of consonants and a basic vowel is displayed (145, 180). In addition, if there is no continuous contact on the touch screen for a predetermined time (150), one syllable formed of consonants and additional vowels composed or combined with the basic vowel and the basic vowel located in the second drag direction is displayed through the touch screen. (170).

Then, repeatedly, if the dragged consonant or vowel is in constant contact with the vowel for a period of time, it detects the third drag and drag direction to one of the radially displayed basic vowels to form a double vowel derived from the additional vowel ( 130,140,170). On the other hand, if the detected third drag direction is not a preset drag direction, i.e., when a third drag is detected in a direction other than the default vowel direction arranged at a radial position, the input of the double vowel is released. One syllable consisting of consonants and additional vowels is displayed (145, 180). In addition, if there is no continuous contact on the touch screen for a predetermined time (150), a consonant and a single vowel formed of a double vowel composed of the main vowel, the main vowel in the second drag direction, and the main vowel in the third drag direction The syllable is displayed (170, 180).

In addition, if the number of drags on the touch screen is three times (160), one syllable composed of consonants and double vowels (170) is displayed (180) without repeating the aforementioned steps (130, 140, 150, 160). Here, double vowels derived from additional vowels include 'ㅞ', 'ㅙ', 'ㅒ' or 'ㅖ'.

Referring to FIG. 1B, a method of inputting Korean characters is as follows.

A, B, C, L, K, K, K, K, K, K, K, K, and H are displayed on the touch screen. When contacted with a predetermined pen, the basic vowel 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or 'ㅡ' are displayed in a substantially radial form, centering on 'B'. On the other hand, ① at the position '위치', ② at the position 'ㅏ', ③ at the position 'TT', ④ at the position 'ㅓ', ⑤ at the position 'ㅡ', ⑥ at the position 'ㅣ' at radial position It is desirable to be.

Therefore, the rules for forming additional vowels and double vowels derived from the basic vowels are as follows.

Among the additional vowels, 'ㅠ, ㅕ, ㅛ' is formed by dragging in the direction of 'TT, ㅓ, ㅗ', and then continuously dragging them back to their original positions (consonants). For example, 'ㅛ' can be synthesized or formed by the continuous drag order of ① + [-①].

Among the additional vowels, 'ㅢ' can be combined or formed by dragging in the direction ⑤ and then continuously dragging in the direction ⑥. Subsequently, if it is necessary to enter the vowels afterwards, it is promised as ⑤ + ⑥.

ㅐ: ② + ⑥

ㅔ: ④ + ⑥

ㅝ: ③ + ④

ㅟ: ③ + ⑥

ㅚ: ① + ⑥

ㅞ: ③ + ④ + ⑥

ㅙ: ① + ② + ⑥

ㅒ: ① + [-①] + ⑥

ㅖ: ④ + [-④] + ⑥

Referring to FIG. 1C, a method of inputting "OK" according to the above-described input rule of Hangul characters will be described.

To combine "okay", drag continuously from the "a" (a) to ① + ② + ⑥ direction and then touch the final "b" (b) to complete a syllable.

In order to combine "bad", drag continuously in the direction of 'ec' (c) and then touch 'b' (d) and 'ㅎ' (e) in order to complete one syllable.

In order to combine 'D', 'D' (f) is continuously dragged in the direction of ② to complete one syllable.

As illustrated in FIG. 1C,

In the above-described Hangul character input method, if it is not continuous contact after dragging to the basic vowel form one syllable to display through the touch screen. On the other hand, if the basic vowel is not selected after continuous contact, the step of receiving a vowel input end command is added to form additional vowels or double vowels from the basic vowel, or as in the above-described Korean character input method. After forming and displaying one syllable, the Hangul character input method of another embodiment may be implemented as follows to determine whether to proceed to the next syllable input step. That is, a schematic flowchart of a Hangul character input method including the step of receiving a vowel input end command is as follows.

First, a consonant is input through the touch screen.

Then, the basic vowel is displayed substantially radially around the input consonant.

Then, one of the basic vowels displayed radially from the consonant is selected.

Thereafter, it is determined whether to receive a vowel input end command through the touch screen.

Then, when the vowel input end command is input, the syllable is formed by the selected basic vowel and the input consonant and displayed.

On the other hand, if the vowel input termination command is not input, the basic vowel forming the additional vowel derived from the selected basic vowel is additionally selected. Thereafter, it is determined whether to receive a vowel input end command through the touch screen. Thereafter, when the vowel input end command is input, the syllable is formed by the additional vowel and the input consonant which are formed and displayed. Here, in the previous step, if the vowel input end command is not input, the basic vowel forming the double vowel is additionally selected. Thereafter, syllables are formed by double vowels and input consonants and displayed.

Here, the default vowel includes' ㅓ ',' ㅏ ',' ㅗ ',' TT ',' ㅣ ', or' ㅡ ', and additional vowels derived from the default vowel include' ㅐ ',' ㅑ ',' ㅔ, 'ㅕ', 'ㅘ', 'ㅚ', 'ㅛ', 'ㅝ', 'ㅟ', 'ㅠ' or 'ㅢ', and the double vowels are 'ㅞ', 'ㅙ', ' ㅒ 'or' ㅖ '.

2A is a schematic flowchart of a Hangul character input method according to another embodiment of the present invention, and FIG. 2B is an exemplary view showing a Hangul character input method on a touch screen according to the embodiment of FIG. 2A.

First, a user input is waited through the touch screen (210).

Thereafter, it is determined whether one of the consonant regions displayed on the touch screen by the user input is in a continuous contact state for a predetermined time (220).

Then, if one consonant is in a continuous contact state, the basic vowel centered on the consonants in contact state, in this embodiment 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or 'ㅡ' Display substantially radially (230). Here, the basic vowels displayed radially are preferably arranged at a predetermined position.

Here, if one consonant is not continuously connected, it is determined whether a double click is detected on one consonant on the touch screen (225). Then, when a double click is detected on one consonant, it is determined whether the contact state is continuous for a predetermined time after the double click (227). Meanwhile, in the double click detection determination step (225), if the double click is not detected, the first consonant input on the touch screen is displayed (280). In addition, when a double click is detected on one consonant, the sound of the consonant is displayed. Then, if a continuous contact state after a double click, the basic vowels around the consonant of the sound in contact, in this embodiment 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or 'ㅡ' Display substantially radially (230). Here, the basic vowels displayed radially are preferably arranged at a predetermined position. On the other hand, in the continuous contact state determination step after a double click for a certain period of time (227), if it is not the continuous contact state, the consonants double-clicked on the touch screen is displayed (280).

Then, the first continuous drag and the direction of the drag from the first consonant 220 or the double clicked consonants 225 and 227 to the basic vowel displayed based on the consonants are determined 240.

Thereafter, after detecting the first drag and determining the drag direction, it is determined whether the contact is continuously made on the touch screen for a predetermined time (250). On the other hand, if the direction of the first drag detected is not a preset drag direction, that is, if a drag is detected in a direction other than the direction of the main bar arranged in a radial position, the input of the main bar is released. Only consonants without vowels are displayed (245,280).

Then, if continuously contacted on the touch screen for a predetermined time, additional vowels and double vowels derived from the main vowel are displayed substantially radially about the contacted main vowel 230. Here, additional vowels derived from the default vowel can be 'ㅐ', 'ㅑ', 'ㅔ', 'ㅕ', 'ㅘ', 'ㅚ', 'ㅛ', 'ㅝ', 'ㅟ', 'ㅠ' or 'ㅢ', and the double vowel may include 'ㅞ', 'ㅙ', 'ㅒ' or 'ㅖ'.

Thereafter, a second drag and drag direction of one of the additional vowels and the double vowels radially displayed around the main vowel is sensed to form additional vowels or double vowels derived from the main vowel (230, 240, 250). That is, it is determined whether the number of drags is twice by counting the number of drags on the touch screen (260), and when the number of drags is twice, the second drag direction is detected to form or synthesize additional vowels or double vowels ( 270).

Then, one syllable by the additional vowel or double vowel is displayed through the touch screen (280). On the other hand, if there is no continuous contact on the touch screen for a predetermined time, the syllables consisting of consonants and the basic vowels located in the first drag direction are displayed (250, 270).

On the other hand, after repeatedly detecting the second drag and drag direction to one of the additional bar or the double bar displayed around the main bar (240), the detected direction of the second drag is a preset drag direction Alternatively, if a second drag is detected in a direction other than in the direction of additional vowels and dual vowels placed in a radial position, the input of the additional vowels or dual vowels is deactivated to produce one Syllables are displayed (245, 280).

Referring to FIG. 2B, a method of inputting Korean characters is as follows.

Continuously drag to '기본' from the basic bar displayed substantially radially around the consonant, and 'ㅘ', '이면', 'ㅚ' are substantially radially around 'ㅗ' if it is in contact for a certain time. Is displayed. That is, additional vowels and double vowels derived from the default vowel 'ㅗ' are displayed.

3 is a schematic flowchart of a Hangul character input method according to another embodiment of the present invention.

First, a user input is waited through the touch screen (310).

Thereafter, it is determined whether one consonant of one of the consonant regions displayed on the touch screen by the user input is in a continuous contact state for a predetermined time (320).

Then, if one consonant is in continuous contact, the vowel is displayed substantially radially around the consonant in contact (330). Here, it is preferable that the vowels displayed radially are arranged at a predetermined position, and in this embodiment, the vowels are 'ㅏ, ㅐ, ㅑ, ㅒ, ㅓ, ㅔ, ㅕ, ㅖ, ㅗ, ㅘ, ㅙ, ㅚ, ㅛ. , TT, ㅝ, ㅞ, ㅟ, ㅠ, ㅡ, ㅢ, |

Here, if one consonant is not in a continuous connection state, it is determined whether a double click is detected in one consonant on the touch screen (325). Then, if a double click is detected on one consonant, it is determined whether the contact state is continuous for a predetermined time after the double click (327). Meanwhile, in the double click detection determination step (325), if the double click is not detected, the first consonant input on the touch screen is displayed (360). In addition, when a double click is detected on one consonant, the sound of the consonant is displayed. Subsequently, in a continuous contact state after a double click for a predetermined time, the vowel is substantially radially displayed based on the consonants of the contacted sound (330). Here, it is preferable that the vowels displayed radially are arranged at fixed positions, respectively. On the other hand, in the step of determining the continuous contact state for a certain period after the double click (327), if it is not the continuous contact state, the consonant double-clicked on the touch screen is displayed (360).

Thereafter, the direction of continuous dragging and dragging from the first consonant 320 or the double-clicked consonants 325 and 327 to the vowel displayed around the consonant is determined (340).

Then, after detecting the drag and determining the drag direction, if the detected drag direction is not a preset drag direction, that is, if the drag is detected in a direction other than the vowel directions arranged at radially fixed positions, respectively, the vowel is detected. The input of is released and only consonants without vowels are displayed through the touch screen (345,360).

Subsequently, if the direction of drag is a vowel direction disposed at a predetermined radial position, the vowel is formed or synthesized 350 to display one syllable through the touch screen 360.

4 is a configuration diagram schematically illustrating a Hangul character input device according to another embodiment of the present invention. Here, descriptions that overlap with the above description will be omitted.

The Hangul character input device according to the present embodiment includes a user input unit 410, a controller 420, a vowel database 430, a vowel synthesizer 440, a consonant synthesizer 450, a syllable forming unit 460, and a display unit. 470.

The user input unit 410 selects and inputs one consonant among Korean consonants displayed on the touch screen. The user input unit 410 may further include an input area for inputting a vowel input termination command in a case where the above-described Korean character input method is not in a continuous contact state. The description of the vowel input end command input in this embodiment is omitted because it is duplicated with the aforementioned Korean character input method.

The display unit 470 displays the basic vowel substantially radially on the touch screen based on the consonants input through the user input unit 410. Meanwhile, the center of the consonant may be radially displayed at a predetermined position by randomly combining the main vowel, the additional vowel derived from the main vowel, or the double vowel. Here, the basic vowels include 'ㅓ', 'ㅏ', 'ㅗ', 'TT', 'ㅣ', or 'ㅡ', and additional collections are 'ㅐ', 'ㅑ', 'ㅔ', 'ㅕ' ',' ㅘ ',' ㅚ ',' ㅛ ',' ㅝ ',' ㅟ ',' ㅠ 'or' ㅢ ', and double vowels include' ㅞ ',' ㅙ ',' ㅒ 'or' ㅖ ' Contains' Meanwhile, the user input unit 410 and the display unit 470 may be implemented with substantially the same touch screen.

The control unit 420 causes the display unit 470 to display the basic vowel substantially radially based on the consonants input through the user input unit 410 or to display additional vowels and double vowels based on the basic vowel. To display. In addition, the control unit 420 determines the number of drags and the direction of the drag for a predetermined time on the user input unit 410 by one of the basic vowels or consonants displayed radially from the consonant through the display unit 470. . In addition, the controller 420 may determine a continuous drag direction and a drag direction on the user input unit 410 for a predetermined time from the additional bar and the double bar that are displayed substantially radially from one of the base bar.

The vowel synthesizing unit 440 synthesizes a basic vowel, additional vowels derived from the basic vowel, or a double vowel corresponding to the number of drags and the direction of dragging of the controller 420 and outputs the synthesized vowel to the syllable forming unit 460.

The consonant synthesizing unit 450 outputs the consonants of the consonant to the syllable forming unit 460 when the consonant synthesizing unit 450 is input by touching the same consonant substantially twice on the user input unit 410.

The syllable forming unit 460 combines vowels by the vowel synthesizer 440 or consonants by the consonant synthesizer 450 to form one syllable and outputs the syllables through the display 470. The syllable forming unit 460 may display only the consonants through the display unit 470 according to the number of drags and the drag direction.

The collection database 430 stores a basic collection, additional collections derived from the basic collection, or a double collection. The controller 420 may receive the vowels corresponding to the number of drags and the drag direction from the vowel database 430 and output the vowels to the vowel synthesizer 440.

The shapes of the vowels and the arrangement of the vowels in all the above-mentioned embodiments are exemplary, and the strokes and strokes that can form the vowels or vowels on the touch screen for vowel input for syllable formation are not particularly limited. This is preferred. For example, as a stroke capable of forming a vowel, '·', '-', and '|' may be arbitrarily arranged around the selected consonant. Also, the illustrated consonants and the arrangement of the consonants are exemplary, and the expression and arrangement of the consonants are not particularly limited to those shown in the drawings.

In addition, the substantially radial display of the vowel in the above-described embodiment is exemplary, and even if the vowel is not directly displayed on the touch screen, the syllable may be formed by judging the dragging and dragging directions to display the finally completed syllable. . For example, when the user is aware of the arrangement of the vowels in advance, it is possible to form a desired syllable without selecting the consonants without seeing the vowels displayed on the touch screen. Embodiments that do not display directly are also possible.
