The Hangul input device 100 includes a polyhedron generating unit 110, a display control unit 120, an input unit 130, and a storage unit 140.

The polyhedron generation unit 110 generates a polyhedron having one or more vowels disposed on each surface. Here, the polyhedron includes a three-dimensional figure enclosed by a planar polygonal plane, and the polyhedron generator 110 includes, for example, a virtual three-dimensional shape such as a tetrahedron, a cube, an octahedron, a dodecahedron, and an icosahedron on the screen. I can display it. Hereinafter, the polyhedron is described as an example, but may be configured in the form of a cube as well as a cube of a cube.

And, vowels include 'ㅏ', 'ㅐ', 'ㅑ', 'ㅒ', 'ㅓ', 'ㅔ', 'ㅕ', 'ㅙ', 'ㅗ', 'ㅘ', 'ㅙ', 'ㅚ' It can include Korean vowels of ',' ㅛ ',' ㅜ ',' ㅝ ',' ㅞ ',' ㅟ ',' ㅠ ',' ㅡ ',', ', and' ㅣ '. And, it is a short vowel ('ㅣ', 'ㅡ', 'ㅗ', 'TT', 'ㅏ', 'ㅓ', 'ㅐ', 'ㅔ') and a double vowel ('ㅛ', 'ㅠ', ' ㅑ ',' ㅕ ',' ㅒ ',' ㅖ ',' ㅘ ',' ㅙ ',' ㅝ ',' ㅞ ',' ㅢ ',' ㅚ ',' ㅟ ').

The display controller 120 displays the polyhedron on the screen, and displays a collection arranged on one surface of the polyhedron in front of the polyhedron according to the touch type for the screen. For example, the user may touch the screen through a touch means such as a finger or a touch fan. In addition, the display controller 120 may display a reference collection of 'ㅡ' or 'ㅣ' on the front of the polyhedron and display a collection of one or more strokes added to the reference bar on one surface of the polyhedron.

In addition, when the front surface of the polyhedron is touched once and then slides to the left or right side of the polyhedron, the display control unit 120 displays the vowel in which one or more strokes are added to the 'ㅣ' vowel on the front of the polyhedron. In addition, when the front surface of the polyhedron is touched once and then slides to the top or bottom surface of the polyhedron, a vowel in which one or more strokes are added to the 'ㅡ' vowel may be displayed on the front of the polyhedron.

Here, a collection in which one or more strokes are added to the 'ㅣ' collection may include any one of 'ㅏ', 'ㅓ', ',', and 'ㅔ', and one or more strokes are added to the 'ㅡ' collection. The vowel may include any one of 'ㅗ', 'TT', 'ㅚ', and 'ㅟ'.

In addition, when the front surface of the polyhedron is touched twice, and then sliding to the left or right side of the polyhedron, the display control unit 120 displays a double vowel in which one or more strokes are added to the 'ㅣ' vowel on the front of the polyhedron. In addition, when the front surface of the polyhedron is touched twice and then slides to the top or bottom surface of the polyhedron, a double vowel in which one or more strokes are added to the 'ㅡ' vowel may be displayed on the front of the polyhedron.

In addition, when the display control unit 120 simultaneously touches two different points on the front face of the polyhedron and then slides to the left or right side of the polyhedron, the display control unit 120 adds one or more stroke numbers to the front of the polyhedron. In the case of simultaneously displaying two different points of the front face of the polyhedron and sliding to the top or bottom face of the polyhedron, a double vowel in which one or more strokes are added to the '-' vowel may be displayed on the front of the polyhedron.

Here, the vowel vowel having one or more strokes added to the 'ㅣ' collection may include any one of 'ㅑ', 'ㅕ', 'ㅒ', and 'ㅖ', and one or more strokes added to the 'ㅡ' collection. The collected double vowels may include any one of 'ㅛ', 'ㅠ', 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', and 'ㅢ'.

In addition, when the display control unit 120 touches the front face of the polyhedron once, and continuously combines the lateral sliding of the polyhedron and the vertical sliding of the polyhedron, the display control unit 120 combines the vowels arranged on the polyhedron according to the combination form to front the polyhedron. One of 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', 'ㅢ', 'ㅚ' and 'ㅟ' may be displayed on the screen.

Meanwhile, the display controller 120 may display a polyhedron having one or more vowels disposed on each side of the polyhedron according to a vowel classification scheme or internal setting on the screen. Here, the vowel classification system may include a single vowel, a double vowel, a high vowel, a middle vowel, a low vowel, a round vowel, a flat vowel, a positive vowel, a vowel vowel, and a vowel.

In addition, the display control unit 120 may rotate the polyhedron by a distance sliding on the screen. In addition, the display controller 120 may rotate the polyhedron in a preset direction whenever the user touches the front face of the polyhedron with a time interval. For example, each time the front face of the polyhedron is touched once, the polyhedron rotates in a left or right direction, and a vowel displayed on one side of the polyhedron may be displayed on the front side.

In addition, the polyhedron may be configured to rotate in the corresponding direction whenever the user touches the upper, lower, left, or right point with respect to the center point of the front face of the polyhedron.

When the vowel input is completed, the display control unit 120 may position the polyhedron to an initial state. For example, the display control unit 120 may position the polyhedron to face the front when one vowel is input.

The input unit 130 inputs a vowel displayed in front of the polyhedron. For example, if the polyhedron is positioned to the front for a threshold time, the input unit 130 may input a collection displayed on the front of the polyhedron positioned for the threshold time.

In addition, the input unit 130 may immediately input the corresponding vowel displayed on the front of the rotated polyhedron when the finger is removed from the screen after sliding.

In addition, the input unit 130 may directly input the corresponding vowel displayed on the front of the polyhedron when the front surface of the polyhedron is touched after sliding. In addition to the above-described input method, the input unit 130 may input a vowel displayed on the front of the polyhedron when the user presses a predetermined button through a key input device (eg, a mouse or a keyboard).

The storage unit 140 stores information about the shape of a polyhedron, consonants and vowels in Korean, various setting values, input vowel input values, and algorithms. Hereinafter, a method of inputting a Korean vowel through a polyhedron in which vowels are arranged through FIGS. 2 to 5 will be described in detail.

2 and 3 show examples of short vowel input through a single touch in accordance with one embodiment of the present invention.

As illustrated in FIG. 2, for example, a reference collection of 'ㅡ' or 'ㅣ' may be displayed in front of the polyhedron, and a collection in which one or more strokes are added to the reference bar may be displayed on one surface of the polyhedron.

In this case, the vowel input may be started by a touch on the front face of the polyhedron, and may be configured such that the polyhedron is initially positioned when the vowel input is completed. Here, the front face of the polyhedron may be defined as one surface of the polyhedron facing the front of the screen.

First, when the user touches the front face of the polyhedron once with one finger in FIG. 2 (a), one or more strokes are added to the 'ㅣ' collection on the side of the polyhedron. At least one of ',' and 'ㅔ' is disposed, and one or more strokes are added to the '-' vowel on a vertical (or up and down) plane, and among 'ㅗ', 'TT', 'ㅚ', and 'ㅟ'. At least one may be arranged.

In the present embodiment, the 'ㅏ', 'ㅓ', 'ㅐ', and 'ㅔ' vowels are arranged on the side, and the 'ㅐ' and 'ㅔ' vowels are arranged on the rear side, depending on the sliding direction of the left or right side. 모음 ', or' ㅔ 'vowels are displayed in front, and' ㅗ ',' TT 'vowels are arranged on the upper and lower surfaces, respectively.

When the user touches the front face of the polyhedron once and then slides a finger in the left direction, the polyhedron is rotated as shown in FIG. As shown in (c) of FIG. 2, when the 'ㅓ' collection is located at the front, the 'ㅓ' collection is input.

3, when the user touches the front face of the polyhedron once to continue sliding the finger in the left direction to input the 'ㅔ' vowel, FIGS. In turn, the polyhedron is rotated to the left and the 'ㅔ' gradually is located in front. And, as shown in (e) of FIG. 3, when the 'ㅔ' collection is located in front, the 'ㅔ' collection is input.

The vowels 'ㅏ' and 'ㅐ' can be entered in a similar way. That is, when the user touches the front face of the polyhedron once and then slides a finger in the right direction, the polyhedron is rotated and the 'ㅏ' collection is gradually located at the front, and the 'ㅏ' collection is input. Then, in order to input the '모음' vowel, if the user touches the front face of the polyhedron once and then slides the finger in the right direction, the polyhedron rotates to the right and the 'ㅐ' vowel gradually moves to the front side. And the vowel is entered. Hereinafter, a method of inputting a double vowel through FIG. 4 will be described later.

4 illustrates an example of a double vowel input through multiple touches according to an embodiment of the present invention.

As shown in (a) of FIG. 4, when the front face of the polyhedron is touched twice or two different points on the front face of the polyhedron are simultaneously touched, '복', ' At least one of ㅕ ',' ㅒ ', and' ㅖ 'is placed on the side, and one or more strokes are added to the' ㅡ 'vowel, and the' ㅛ ',' ㅠ ',' ㅘ ',' ㅝ ',' At least one of V ',' V ', and' V 'may be disposed in the vertical plane.

In this embodiment, 'ㅑ', 'ㅕ', 'ㅒ', and 'ㅖ' are arranged on the side, and 'ㅒ' and 'ㅖ' are arranged on the rear side, and 'ㅒ' depending on the sliding direction of the left or right side. , Or 'ㅖ' is displayed in front, and 'ㅛ' and 'ㅠ' are arranged in a vertical plane.

For example, if the user touches the front face of the polyhedron twice and then slides a finger downward, the polyhedron is rotated downward as shown in FIG. And, as shown in (c) of Figure 4 when the 'ㅠ' collection is located in front of the 'ㅠ' collection is input.

In this case, any one of 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', and 'ㅢ' may be displayed on the upper surface 12 according to a setting value. Such double vowel input of 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', and 'ㅢ' may be input in the same manner as in FIG. 5 to be described later.

5 illustrates an example of a double vowel input composed of a vowel combination according to an embodiment of the present invention.

In the form of a double vowel such as 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', and 'ㅢ', for example, 'ㅘ' is a combination of short vowels 'ㅗ' and 'ㅏ', 모음 'vowel is a combination of short vowel' TT 'and' ㅔ '. Using this vowel combination form, a double vowel such as 'ㅘ', 'ㅝ', 'ㅙ', 'ㅞ', and 'ㅢ' may be input.

For example, in FIG. 5 (a), the user touches the front face of the polyhedron once with a finger and slides it, and as shown in FIGS. 5 (b) and 5 (c), the 'ㅗ' collection is faced upward. Rotate until it is at

Then, again sliding to the right direction, as shown in (d) and (e) of Fig. 5, by rotating the polyhedron until the 'ㅏ' collection is located in front of the 'ㅗ' and 'ㅏ' collection 'Vowel' collection is entered. At this time, a 'ㅘ' collection may be displayed on the front of the polyhedron, and at least one of '' and 'ㅟ' may be displayed on the upper surface 14.

As described above, the method of inputting the vowel can be summarized as shown in Table 1 below.

collection Touch type Sliding direction (side) A single Right ㅓ single Left ㅗ single Prize ㅜ single Ha ㅐ single Right (long sliding) ㅔ single Left (long sliding) ㅑ revenge Right ㅕ revenge Left ㅒ revenge Right (long sliding) ㅖ revenge Left (long sliding) ㅛ revenge Prize ㅠ revenge Ha ㅘ single Top + Right ㅝ single Lower + Left ㅙ single Up + Right (long sliding) ㅞ single Lower + left (long sliding) ㅚ single Up + 1 touch ㅟ single +1 touch ㅢ Multiple + Single none ㅣ single First touch ㅡ revenge none

In Table 1 above, a single touch is a touch type in which a single finger touches the front face or the screen of a polyhedron once, and a plurality of touches means a single finger touching the front face or screen of a polyhedron twice or two fingers. This includes the case where the front face of the polyhedron or two different points of the screen are simultaneously touched. The screen may be a screen on which a polyhedron is displayed or a touch area configured to correspond to a screen on which a polyhedron is displayed.

Specifically, in Table 1, for example, the notation of 'up + right' in the 'ㅘ' vowel input indicates a form in which the upward sliding of the polyhedron and the sliding of the rightward of the polyhedron are continuously combined. In addition, in the 'ㅚ' vowel input, after sliding a single direction, the sliding direction is slid upward until the 'ㅗ' collection is located at the front side, and then the 'ㅚ' collection is inputted when the front finger is touched once again. It can be.

In addition, the '모음' vowel input indicates that the '복수' vowel can be automatically input when a single touch is made after a plurality of touches of the front face of the polyhedron without additional sliding. Specifically, when the front of the polyhedron is touched twice, or the front of the polyhedron or two different points on the screen on which the polyhedron is displayed at the same time, and then touches the front or the screen of the polyhedron once, a 'ㅢ' vowel is input. Can be.

In addition, the 'ㅣ' vowel input indicates that when the user touches the front face once, the 'ㅣ' vowel can be input when the finger is removed from the screen or automatically after a threshold time.

In the vowel input of 'ㅡ', a plurality of touches of the front face of the polyhedron are not required, and the 'ㅡ' vowel can be automatically input when the finger is removed from the screen or after a threshold time.

However, the present invention is not limited thereto. After one touch on the front face of the polyhedron with a single finger, when the threshold time elapses automatically, the 'ㅡ' vowel is input or after one touch on the front face of the polyhedron, the threshold time automatically passes. It may be implemented that a 'ㅣ' vowel is input.

As an example, the vowel input method shown in Table 1 may be variously implemented according to the position of the vowel disposed on the polyhedron, the type of the polyhedron, the internal setting value, and the algorithm.

In addition, the above-described polyhedron may be composed of a transparent three-dimensional figure so that all of the vowels disposed on each side appear. In addition, the polyhedron may include a form in which various 3D characters are divided into virtual three-dimensional shapes, and as the characters rotate, collections disposed on each side of the character divided into virtual three-dimensional shapes may be displayed on the screen. .

In addition, not only the polyhedron is touched, but also the operation and vowel input of the above-described polyhedron may be performed according to the touch type of the user who is touched on the screen on which the polyhedron is displayed.

In addition, the aforementioned polyhedron may be displayed on a plurality of screens and provided to a user. For example, the above-mentioned polyhedron with a single vowel and the polyhedron with a double vowel can be displayed together on the screen. In addition, the above-described vowels arranged in the polyhedron may be displayed in a predetermined region of the Hangul input screen so that the user may recognize the vowels arranged in the corresponding polyhedron.

In addition, in the double vowel input in the form of a combination of the above-mentioned short vowels, not only a vowel combination form by a plurality of sliding directions, but also a polyhedron in which pre-combined double vowels are arranged on the screen, It may be implemented in the form of input.

In addition, the vowel input method using the above-described polyhedron may be used when inputting consonants and various other symbols and characters. Consonants include a, b, c, d, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k Forms such as ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ may be included. Like vowels, the vowel input method described above may be utilized by being disposed on each side of a polyhedron.

In addition to the form of directly touching a polyhedron, a terminal having a touch area configured separately may be configured to input Korean characters in a manner in which a virtual polyhedron moves according to a touch position and type in the corresponding touch area.

As described above, the Hangul input can be performed through the three-dimensional visual effect in the existing flat text input, thereby increasing the interest of the emotional users.
