DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

1 is a block diagram of a character input apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the character input apparatus 100 includes a polyhedron generator 110, a display controller 120, an inputter 130, and a storage 140.

The polyhedron generator 110 generates a polyhedron having one or more characters disposed on each side thereof. Here, the polyhedron may include a three-dimensional figure enclosed by a plane polyhedron, and the polyhedron generator 110 may generate a virtual three-dimensional shape such as a tetrahedron, a cube, an octahedron, a dodecahedron, or a icosahedron. 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.

In addition, the character disposed on the polyhedron may include any one of alphabetic characters (ie, English alphabet), consonants, vowels, numbers, and symbols. Here, the alphabetic characters include the small and small alphabetic characters of 'a' to 'z', and the Korean consonants are 'ㄱ', 'b', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', It includes the basic forms of 'ㅇ', 'ㅈ', 'ㅊ', 'ㅌ', 'ㄷ', 'ㅋ' and 'ㅎ'. In the following embodiment of the present invention will be described by taking the English alphabet and Hangul consonants as an example, of course, it is not limited thereto.

In addition, the above-described polyhedron generation unit 110 may generate a polyhedron in which a plurality of characters are arranged in groups of characters. In this case, each character may be assigned to a corresponding character group according to a set rule, and the corresponding characters may be grouped and displayed in a form of an object representing each character group. For example, in the case of the English alphabet, four to five alphabetical letters are assigned to each character group in alphabetical order, and the corresponding character groups may be arranged in the form of speech bubbles on each side of the polyhedron.

In the case of English letters, since it consists of 26 letters 'a' to 'z', in the case of a six-sided polyhedron, four letter groups consisting of five English letters and two letter groups consisting of three English letters Each may be disposed on each side of the polyhedron. At this time, according to the characteristics of each word may be grouped into a single letter group, for example, vowel 'a', 'e', 'i', 'o', 'u' are grouped into a single letter group on one side of the polyhedron Can be deployed.

In addition, when the user touches a polyhedron and slides to select any one character group, the characters included in the character group are preferably distributed one by one on each side of the polyhedron, so that subsequent character input is more efficiently performed. Do it.

Then, a character is input by a single touch of touching the screen on which the front face or the face of the polyhedron is displayed with one finger and the screen on which the face or face of the face is displayed two or more times with one finger, or a screen or facet with two fingers. In the case of a character input by a plurality of touches simultaneously touching the front surface of the character, the characters may be displayed to be distinguished from each other by a difference in size, color, font, and thickness of the character.

In addition, when characters input by a single touch or a plurality of touches are grouped into character groups, respectively, shapes of objects (eg, speech bubbles, etc.) displaying each character group may be differently displayed.

In addition, the polyhedron generator 110 may generate a first polyhedron and a second polyhedron in which a character group including one or more characters is disposed on each side.

The display control unit 120 displays the polyhedron on the screen, and displays the characters distributed on one surface of the polyhedron in front of the polyhedron according to the type of touching the front face of the polyhedron or the screen on which the polyhedron is displayed.

Here, the display controller 120 recognizes the case of simultaneously touching the front face of the polyhedron or the screen on which the polyhedron is displayed with two fingers, and recognizes the same as the case of touching the front face of the polyhedron or the screen on which the polyhedron is displayed twice with one finger. You can control the direction.

That is, the “touch on, touch off, touch on” operation performed by one finger is recognized in the same manner as touching two fingers simultaneously. This is to make it easy to enter a character with one finger even when operating the mobile device with only one hand.

In addition, when more than one polyhedron is required, the display controller 120 may display the first polyhedron generated through the polyhedron generator 110 on the left side of the screen, and display the second polyhedron on the right side of the screen.

Hereinafter, the configuration of the display control unit 120 will be described in more detail with reference to FIG. 2.

2 is a detailed block diagram of a display controller included in the character input device.

As shown in FIG. 2, the display controller 120 includes a rotation controller 122, a character distributor 124, a character switcher 126, and a state detector 128.

The rotation control unit 122 controls the rotation direction of the polyhedron according to the type of touching the front face of the polyhedron or the screen on which the polyhedron is displayed. For example, a user may touch a single screen or a plurality of screens through a touch means such as a finger or a touch fan. And, if the user slides the polyhedron to one side, the rotation control unit 122 may rotate the polyhedron accordingly. For types of touching the screen, refer to Tables 2 and 3 to be described later.

The rotation controller 122 recognizes the same plurality of touches when the user touches the screen on which the polyhedron is displayed or the front face of the polyhedron twice or simultaneously touches two different points on the screen on which the polyhedron is displayed. The rotation of the polyhedron can be controlled.

In addition, the rotation controller 122 may rotate the polyhedron by a distance sliding on the screen. The rotation controller 122 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.

The character distributor 124 distributes the characters included in the character group to a predetermined surface. Specifically, the polyhedron is rotated along the direction in which the finger slides so that one or more characters included in the character group located on one side of the polyhedron positioned at the front face are distributed and displayed on each side of the polyhedron. In this case, when one surface of the polyhedron is rotated or completely positioned in front of the polyhedron, at least one or more characters included in the character group located on one surface of the polyhedron may be distributed and displayed.

Specifically, when the alphabets included in the letter group distributed on the front face are vowels 'a' to 'u', the letter distribution unit 124 may include 'a', 'e', on each side of the polyhedron. You can distribute the 'i', 'o', and 'u' collections one by one, and display the 'a' at the beginning of the character group in front of the polyhedron.

Here, when the character group is displayed by an icon such as a speech bubble, since the number of characters included in the speech bubble is reduced, the size of the speech bubble may be displayed accordingly. In addition, in the case of a character input by a single touch and a character input by a plurality of touches, the characters may be distinguished from each other by a difference in size, font, thickness, etc. of the characters.

In addition, the character distributing unit 124 may be input by using a plurality of touches included in a corresponding character group when the surface on which the character group including one or more characters input by a single touch or a plurality of touches is located in front of the polyhedron is positioned at the front. The characters to be distributed on each side of the polyhedron may be distributed, but the first alphabetical character in the corresponding character group may be distributed to the front of the polyhedron.

The character switching unit 126 may change and display the character displayed on the polyhedron by receiving the character switching signal. For example, when a user performs character conversion from English to Korean through an input device such as a keyboard, the character switching unit 126 may change each side of the polyhedron on which an English letter is displayed to Korean. Also, in another embodiment, the character switching unit 126 may receive the character switching signal and transmit the same to the polyhedron generator 110 to regenerate the polyhedron with the corresponding changed character.

Here, the user may directly perform the character switching on the touch screen, and a menu for character switching may be provided on the screen so that the character switching through the corresponding menu may be performed. In addition, character switching may be performed according to a combination of a preset touch type or a setting key.

Then, the state detection unit 128, after the screen in front of the polyhedron or the polyhedron is a single touch or a plurality of touches, if the finger is removed from the screen without sliding or the threshold time passes. The polyhedron can be placed in the initial state. For example, the state detector 128 may position the polyhedron if the polyhedron is not touched for a predetermined time after the English letter is input.

Referring back to FIG. 1, the input unit 130 inputs a character displayed on the front of the polyhedron. For example, if the polyhedron is positioned to the front for a threshold time, the input unit 130 may input an English letter displayed on the front of the polyhedron positioned for the threshold time.

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

The storage unit 140 stores information about the shape of the polyhedron, various characters (English letters, Korean consonants, etc.), various setting values, algorithms, and the like.

Hereinafter, a method of inputting a character through a polyhedron in which an English letter is distributed through FIGS. 3 to 4 will be described in detail.

3 and 4 illustrate a method of inputting an English letter through a polyhedron according to an embodiment of the present invention.

In the embodiment of the present invention, when the character input is a single touch, a character displayed on the front of the polyhedron is basically a touch on operation of touching a screen (a front of the polyhedron or a screen on which a polyhedron is displayed) with one finger and a corresponding touch on operation. The touch input may be input by removing a finger from the screen. Then, the character displayed on the right side of the polyhedron is input by touch on, left sliding once, and touch off operation. In addition, the character displayed on the upper side is input by touch on, sliding down once, and touch off operation. In other words, the characters displayed on each side can be selected according to the direction in which the virtual polyhedron is rotated.

As described above, the single touch includes a case in which one finger touches the screen on which the front face or the polyhedron is displayed with one finger. In addition, after sliding once to any one side of the polyhedron, the number of characters that can be input to the polyhedron is given in Table 1 below, considering that the polyhedron can continuously slide to any one side of the four directions.

Character input method The number of characters that can be entered Touch on, sliding 0 times, touch off One Touch on, sliding one time, touch off 4 Touch on, sliding twice, touch off 4 * 4 Touch On, 3 Sliding, Touch Off 4 * 4 * 4

On the other hand, when the character input by a plurality of touch may have the same number of characters that can be input as Table 1 described above. Here, the plurality of touches include a case in which the front surface of the polyhedron or the polyhedron is touched twice as described above, or two different points of the screen on which the front face or the polyhedron of the polyhedron are simultaneously touched.

Therefore, for the convenience of the user, the sliding is limited to two times, and when a plurality of touches are allowed, the total number of characters (1 + 4 + 4 * 4) * 2 = 42 may be input. That is, it can be seen that all English characters can be input as one polyhedron. Here, the “touch on, touch off, touch on” operation may be implemented in the form of touching two fingers simultaneously in the case of a touch screen supporting multiple touches.

On the other hand, Table 2 below summarizes the method for inputting English characters in a polyhedron. Here, the touch-on ('ON') to touch the finger on the screen, the touch-off ('OFF') to release the finger, the left sliding ('L'), the right sliding ('R'), the upper side relative to the front of the polyhedron Sliding (U) and lower sliding (D) will be referred to as abbreviations in parentheses for convenience. In addition, Table 2 is basically based on a single touch type, and ('ON, OFF, ON') may be replaced by a method of touching two fingers simultaneously on the screen ('TWO-FINGERS ON').

Input character Touch type Character group a ON, D, OFF One b ON, L, OFF 2 c ON, L, D, OFF 2 d ON, L, U, OFF 2 e ON, D, D, OFF One f ON, L, L, OFF 2 g ON, L, R, OFF 2 h ON, U, OFF 3 i ON, D, U, OFF One j ON, U, D, OFF 3 k ON, U, U, OFF 3 l ON, U, L, OFF 3 m ON, U, R, OFF 3 n ON, R, OFF 4 o ON, D, L, OFF One p ON, R, D, OFF 4 q ON, R, U, OFF 4 r ON, R, L, OFF 4 s ON, R, R, OFF 4 t ON, OFF, ON, D, OFF 5 u ON, D, R, OFF One v ON, OFF, ON, D, L, OFF 5 w ON, OFF, ON, D, R, OFF 5 x ON, OFF, ON, U, OFF 6 y ON, OFF, ON, U, L, OFF 6 z ON, OFF, ON, U, R, OFF 6 Space ON, OFF - Back-space ON, OFF, ON, L, OFF -

In Table 2, each alphabetic character is included in each character group 1-6. For example, (b), "c", "d", "f", and "g" are tied to the second character group. As such, the forms of classifying the alphabetic characters into each character group may be, for example, in accordance with the arrangement order of the alphabet, the pronunciation characteristics of the alphabet, or other set internal rules.

In Table 2, the characters belonging to the fifth and sixth character groups may start with a plurality of touches. In addition, the blank may be input in a process of 'touch on, touch off', and the back space may be input in a process of 'touch on, touch off, touch on, left sliding, touch off'. .

For example, when the input character is 'a', 'a' may be input in a process of touching a finger on the screen, sliding down, and then releasing the finger from the screen. Hereinafter, a method of inputting the above-described English letters 'a' and 'z' among English letters will be described with reference to FIGS. 3 and 4.

As shown in (a) of FIG. 3, in the case of the English alphabet of Table 2, since the alphabet consists of 26 letters 'a' to 'z', in the case of a six-sided polyhedron, five alphabetic characters are present on each side. Four letter groups consisting of two, and two letter groups consisting of three alphabets may be arranged in a speech bubble form on each side of the polyhedron. At this time, according to the characteristics of each word may be grouped into a single character group, for example, 'a', 'e', 'i', 'o', 'u' vowels are grouped into the first character group 302 polyhedron It can be displayed on the upper surface of.

Here, for the character group of the English characters that have multiple touches, the form of an icon such as a speech bubble enclosed by the character group is different from the character group of the English characters with a single touch, or by changing the color, thickness, etc. of the characters included in the character group. It may be easy to distinguish between a touch and a plurality of touches. For example, in the case of the fifth and sixth character groups 304 and 306 which are the character groups of the multi-touch alphabet letters, the speech bubble border may be dotted so as to be distinguished from the character groups of the single-touch alphabet letters.

On the other hand, as shown in (b) and (c) of Figure 3, in order to input the alphabet 'a' belonging to the first character group 302, after touching the screen on which the front or polyhedron of the polyhedron is displayed, When the character group to which a 'belongs is slid to the lower side of the disposed polyhedron, the polyhedron is rotated in the sliding direction, and each character of the character group to which' a 'belongs is distributed one by one based on a preset value on each side of the polyhedron.

For example, each of the alphabet letters 'a', 'e', 'i', 'o', and 'u' included in the first character group 302 is arranged on the left, right, bottom, and front sides of the polyhedron. Here, 'a' located at the front of the characters belonging to the character group may be distributed and input in front of the polyhedron (see 'a' input method in Table 2).

Here, each character belonging to the character group may be directly displayed on the face of the polyhedron, or a speech bubble containing each character may be displayed one on the face of each polyhedron while maintaining the shape of the speech bubble described above. In this case, the size of the speech balloon may be adjusted according to the number of characters included in the speech bubble, and the speech bubble of the character located in front may be removed.

In addition, the English letter 'u' may be input in a process of touch on, bottom sliding, right sliding, and touch off in FIG. 3 (a) (see 'u' input method of Table 2). That is, 'u' may be input in a continuous right sliding operation in a state in which 'a' is located at the front.

If the screen touch does not occur after the touch-off or for a predetermined time, the polyhedron may be positioned at the initial position.

On the other hand, as shown in (a) to (e) of Figure 4, the alphabet letter 'z' belonging to the sixth character group 304, after a plurality of touch ('ON, OFF, ON'), the upper sliding, the right It may be input by a process of sliding and touching off.

Here, referring to the input method of the alphabet letter 'z' in Table 2, in the case of a plurality of touches consisting of 'ON, OFF, ON', the screen may be 'touch on, touch off, touch on' with one finger, It can be performed in the form of touching with two fingers at the same time.

On the other hand, in addition to the above-described English letters, the consonants of the Hangul can be input through a three-dimensional polyhedron.

Table 3 summarizes the consonant input method of Hangul as a table. Table 3 is basically based on a single touch type, and ('ON, OFF, ON') may be replaced by a method of touching two fingers simultaneously on the screen ('TWO-FINGERS ON').

Input character Touch type Character group A ON, R, OFF One N ON, D, OFF 2 C ON, OFF, ON, R, OFF One D ON, D, D, OFF 2 M ON, OFF, ON, U, OFF 4 ㅂ ON, U, OFF 4 S ON, OFF, ON, L, OFF 3 ㅇ ON, OFF, ON, D, OFF 2 ㅈ ON, L, OFF 3 H ON, L, L, OFF 3 ㅌ ON, OFF, ON, R, R, OFF One ㅍ ON, U, U, OFF 4 Lol ON, R, R, OFF One ㅎ ON, OFF, ON, D, D, OFF 2 Space ON, OFF -

In Table 3, each basic consonant is included in each corresponding character group 1-4. For example, 'ㄱ', 'ㄷ', 'ㅌ', and 'ㅋ' are tied to the first character group. As such, the form of classifying the consonants into each character group may be based on the characteristics of each consonant (for example, sound position, presence or absence of sound, strength of the sound, articulation method, etc.) or other set internal rules. The blank may be input by a process of touching a finger and touching off the screen.

In general, in an input device such as a smart phone, a user often holds the device with both hands and inputs it with two thumbs. Therefore, the polyhedrons with the consonants in Table 3 and the vowels included in the character group are distributed to the screen, respectively, so that the left-hand thumb is a polyhedron for consonant input, and the right-hand thumb is a polyhedron for vowel input. Hangul input can be made by controlling.

Here, suppose that a polyhedron arranged with consonants included in a character group is located on the left side, and the user inputs consonants with the left thumb.

For example, when the input character is 'ㄱ', it indicates that the input may be performed by touching a finger on the screen, sliding the right side, and then releasing the finger from the screen.

In addition, the consonants 'ㄷ', 'ㅌ', 'ㅇ', 'ㅎ', 'ㅅ' and 'ㅁ' in Table 3 start with a plurality of touches of 'ON, OFF, ON', specifically, a screen with one finger. 'Touch On, Touch Off, Touch On'. Such a form may be recognized as the same operation by touching one's touch, touching off, or touching on, or by simultaneously touching two fingers with one finger.

Hereinafter, a method of inputting consonants 'ㄱ' and 'ㅂ' among Korean consonants will be described with reference to FIGS. 5 and 6. For reference, FIG. 5 and FIG. 6 refer to the character group notation shown in Table 3, and each character group is appropriately disposed on each side of the polyhedron. At this time, for example, the characters 'ㄱ' and 'ㅌ' are included in the same character group, but the touch types may be different as shown in Table 3, which means that when the polyhedron is rotated to the character group, the characters belong to the character group. Can be distinguished in the form arranged on each side of the polyhedron.

5 and 6 illustrate a method of inputting Korean consonants through a polyhedron according to an embodiment of the present invention.

As shown in (a) of FIG. 5, in the case of a Korean consonant, since it basically consists of 14 characters of 'a' to 't', three or four consonants are bound to four character groups, respectively, and a polyhedron It can be placed on each side of the. In this case, each character group may be grouped according to the characteristics of each consonant (for example, sounding position, presence or absence of sound, intensity of sound, modulation method, etc.).

As shown in (a) to (c) of FIG. 5, the consonant 'b' belonging to the first character group 502 may be input through a process of right sliding and touch off after a single touch on the screen. . Herein, 'ㅌ' and 'ㄷ' included in the same group 502 may be removed from the screen notation since the single touch is performed.

In addition, as shown in (a) to (c) of FIG. 6, the consonant 'ㅂ' belonging to the fourth group of characters 504 may be input by a process of sliding upward and touching off after a single touch on the screen. . Here, 'ㅁ' included in the same group 504 may be removed from the screen notation since it is after a single touch.

7 illustrates a method of distinguishing characters input by a single touch or a plurality of touches according to an embodiment of the present invention.

In the case of consonants having a plurality of touches, as illustrated in FIGS. 7A and 7B, font colors, sizes, and thicknesses of letters may be distinguished from other consonants, or as lower character groups 503. It can be bundled so that the user can distinguish it. In addition, in addition to the shape of the icon, such as a speech bubble grouping into a group of characters, or by changing the color, thickness, etc. can be easily distinguished between a single touch and a plurality of touch.

Meanwhile, the screen described above may be a screen on which a polyhedron is displayed or a touch area configured on the device in correspondence with a screen on which a polyhedron is displayed.

In addition, the character input method shown in Table 2 and Table 3 described above, as an example, variously implemented according to the position of each character group including the character or characters disposed on the polyhedron, the type of the polyhedron, the internal setting value and the algorithm. Of course it can be.

In addition, the text input device 100 may be mounted in a mobile communication terminal. The mobile communication terminal is, for example, a wireless communication device that ensures portability and mobility, and includes a PCS (PeRonal Communication System), GSM (Global System for Mobile communications), PDC (PeRonal Digital Cellular), PHS (PeRonal Handyphone System), PDA (PeRonal Digital Assistant), International Mobile Telecommunication (IMT) -2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (WBRO) terminal, etc. It may include a handheld based wireless communication device.

In addition, the above-described polyhedron may be configured as a transparent three-dimensional figure so that all of the characters or groups of characters including the characters disposed on each side thereof 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, characters disposed on each side of the character divided into virtual three-dimensional shapes may be displayed on the screen. .

In addition, the aforementioned polyhedron may be displayed on the screen in plurality and provided to the user. For example, a polyhedron arranged with the terminal sound included in the character group, a polyhedron arranged with the compound sound included in the character group, and a polyhedron arranged with the vowel and the symbol included in the character group may be displayed together on the screen.

In addition, the characters distributed to the above-described polyhedron may be displayed on a predetermined area of the character input screen so that the user may collectively recognize the characters distributed to the corresponding polyhedron.

In addition, the character input method using the above-described polyhedron may be utilized when inputting vowels. Vowels are short vowels ('ㅣ', 'ㅡ', 'ㅗ', 'TT', 'ㅏ', 'ㅓ', 'ㅐ', 'ㅔ') and double vowels ('ㅛ', 'ㅠ', 'ㅑ' ',' ㅕ ',' ㅒ ',' ㅖ ',' ㅘ ',' ㅙ ',' ㅝ ',' ㅞ ',' ㅢ ',' ㅚ ',' ㅟ '). In this case, the vowels may be arranged on each side of the polyhedron in the appropriate number as in the above-described English letters or consonants, and may be input using the input methods of Tables 2 and 3.

In addition, the above-described character input method using a polyhedron may be utilized when inputting a consonant sound. Blessed consonants include 'ㄲ', 'ㄸ', 'ㅆ', 'ㅉ', 'ㅃ', 'ㄳ', 'ㄵ', 'ㄶ', 'ㄺ', 'ㄻ', 'ㄼ', 'ㄽ', 'ㄾ', 'ㄿ', 'ㅀ', and 'ㅄ' may be included. At this time, each of the four consonants are arranged in an appropriate number and arranged on each side of the polyhedron, and may be input using the input methods of Tables 2 and 3.

Specifically, 'ㄲ', 'ㄸ', 'ㅆ', 'ㅉ', 'ㅃ' as the first character group, 'ㄵ' as the second character group, 'ㄶ', 'ㅄ', and as the third character group ' ㄺ ',' ㄻ ',' ㄼ ',' ㄽ ',' 4 'character groups' ㄾ', 'ㄿ', 'ㅀ' are grouped and placed on each side of the polyhedron. Each consonant bound to may be disposed one or more on each side of the polyhedron.

In addition, the character input method using the above-described polyhedron may be utilized when inputting numbers and various other symbols. For example, a symbol may include a mathematical symbol and various types of special characters, and as described above, may be arranged in a polyhedron grouped with each character group.

In addition, a switching menu and a switching key may be used to convert the polyhedron with the terminal sound of Table 3 from the above-described polyhedron to the polyhedron with the double-tone sound. have.

In addition to the form of directly touching the polyhedron, in the case of a terminal configured with a separate touch area, the Hangul may be input in a manner in which the virtual polyhedron moves according to the touch position and the touch type in the corresponding touch area. .

In this way, by enabling the text input through the three-dimensional visual effect in the conventional flat text input can increase the interest of the emotional users. In addition, through the three-dimensional shape it is possible to increase the convenience, familiarity and learning effect of the character input of the disabled, senior citizens, foreigners or young children.

In addition, conventionally, when a character is input in the touch screen by a button method, it is necessary to accurately input the character with a finger that is relatively larger than the character on the touch screen, causing inconvenience such as a decrease in input speed and a typo. However, in the embodiment of the present invention, the character input can be made easier by only the sliding direction and the number of sliding.
