At this time, one consonant button 110 may represent one consonant. Also, one consonant button 110 may display two or more consonants, and the displayed consonant may be selected by a predetermined input method. The arrangement of the consonants can be made in a manner appropriate to a total of nine buttons as shown in 110 of FIG. 1 based on the representative consonant arrangement order of the Hangul 2 bearded keyboard. At this time, the consonant consonant is a consonant with a high frequency of use and close to the basic type, and a, b, c, d, k, f, g, The sub-consonants can be included in the following buttons:,, ㅌ, ㅋ,,, ㅎ,, 에,, and ㅅ respectively. When one consonant button 110 displays two or more consonants, the representative consonant in the button is displayed at the center, and the lower consonants in the button are positioned at the upper right, upper left, lower right, or lower left And its size may be smaller than the representative consonant. The consonant button 110 may further include a consonant sound (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) and a special character. The consonant consonant and the special character are positioned on the upper right side, , The lower right or lower left, and its size may be smaller than the representative consonant.

The vowel button 120 may be composed of two horizontal and three vertical buttons (2X3 structure) based on the upper right of the virtual keyboard. The arrangements of the vowels can be made in a suitable manner for a total of six buttons as shown in 120 of FIG. 1 based on the arrangement order of the representative vowels of the Hangul 2 bearded keyboard. In this case, the representative vowel is a vowel close to the basic type, and may correspond to a, ㅓ, ㅗ, ㅜ, ㅡ, ㅣ. The sub-vowels are ㅑ, ㅕ, ㅛ, ㅠ, ㅑ can be included in a button, ㅕ in ㅓ button, ㅛ in ㅗ button, ㅠ in ㅜ button respectively. At this time, one vowel button 120 may represent one vowel.

When one vowel button 120 displays two or more vowels, the representative vowel in the button is displayed at the center, and the lower vowel in the button is positioned at the upper right, upper left, lower right, and lower left And its size may be smaller than the representative vowel. In addition, the vowel buttons 120 may further include special characters in addition to the vowels, and the special characters may be displayed at the upper right, upper left, lower right, or lower left of the center of the representative vowel, May be smaller than the representative vowel.

The special character change button 130 may be a button for switching from a Korean keypad or an English keypad to a special character keypad for inputting a special character displayed or not displayed on a Korean keypad or an English keypad. In addition, the special character change button 130 may be located at the lower left of the virtual keypad structure 100.

The Korean-English conversion button 140 may be a button for switching from the Korean-language keypad to the English-language keypad. At this time, the Korean-English conversion button 140 may be located in the same column as the special character change button 130 and may be located on the right side of the special character change button 130. [

The interval button 150 may be a button for inputting a space between a character and a character. At this time, the interval button 150 may be located on the right side of the Korean-English conversion button 140 and may be located in the same column as the special character conversion button 130 and the Korean-English conversion button 140.

The delete button 160 may be a button for deleting one spelling in the English keypad, one vowel or consonant in the Korean keypad, or one character. In addition, the special character keypad may be a button for deleting one special character or a plurality of special characters. At this time, the erase button 160 may be located in the same column as the interval button 150. [

The input button 170 may be a button serving as an enter key. Further, the input button 170 may be located in the same column as the erase button 170.

The preview button 180 may be a button for displaying a selected key in order to reduce a typo caused when a user does not properly view a character selected by the user because the user presses the finger when the keypad is selected. The preview button 180 may be a button that can be selected. For example, in the case of a button including a plurality of keys, in the case of selecting twice, another key included in one button can be selected. Therefore, when the same character is repeatedly input, Can be used.

In this case, "Select" is defined as meaning that a button is touched or clicked, and "Input" is defined as meaning that a selected character on the screen is output as an input according to a selection.

Meanwhile, a virtual keypad according to an embodiment of the present invention may include a virtual keypad providing server (not shown) or another server (not shown) operating in cooperation with a virtual keypad providing server, When transmitting a program, an app page, a web page, etc., the mobile terminal may install or open a virtual keypad application, a program, an app page, a web page, Also, a service program may be run on a mobile terminal using a script executed in a web browser.

The virtual keypad providing server or other interworking server can exchange data with each other through the communication object.

2 is a diagram illustrating a keypad for explaining a Hangul keypad in the virtual keypad structure of FIG. Referring to FIG. 2, the virtual keypad structure 100 of the present invention includes a fewer number of buttons than a QWERTY keyboard, i.e., a keyboard including one character in one button, (Consonants, vowels, alphabets, etc.) of the user. A key may be input in which one button shares a plurality of keys or a combination of keys or one button is shared according to a long touch.

For example, we can share a button with a button located at (2,1) coordinates, and a button can be created by a combination of a and l, Press and hold the button for a long time. In summary, when consonants, consonant sounds, and consonant sounds share one button in the consonant button 110, one touch or selection is required to input a consonant and a preview button 180 (To be described later in detail), the user can input a sound by pressing and holding the consonant button 110 for a long time. Accordingly, even if the number of keypads is reduced, one key is shared by a plurality of keys, and a plurality of keys can be input by one button according to the input method.

The Korean keypad of the virtual keypad structure 100 is composed of five horizontal buttons and four vertical buttons. The consonant buttons 110 are arranged up to (3, 3) with respect to the coordinates (1,1) (1, 4), (1,5), (2,4), (2,5), (3,4), and (3,5)

The strong consonant sounds are input by pressing the consonant button 110 twice while the consonant consonants are depressed by the consonant button 110 for a long time. Can be input by pressing the button 120 twice.

Here, the virtual keypad further includes a pre-view button 180 for previewing a selected character when a character included in the keypad is selected. The input key is displayed at the center of the preview button 180 , The upper left or upper right may display a different key than the one displayed in the center (if the key displayed at the center is a subkey, the subkey is displayed. If the key displayed at the center is a subkey, the representative key is displayed). The preview button 180 may be arranged at the same ratio in the partial areas of the selection where the characters are selected adjacent to the selected button, the selected button, and the diagonal line, with the letter centered on the upper right corner or the upper left corner of the selected button . At this time, the preview button 180 may be implemented in a shape such as a circle or a rectangle, and the preview button 180 may be a button for inputting a preview character when a preview character is selected.

For example, if you repeatedly enter the keys in the button, that is, if you want to enter the key, you can display the key if you type the button twice. That is, the repeated pressing of the button is a method for inputting the sub-key. In other words, if you double-click on a shortcut, the shortcut key will be selected, making it difficult to enter the shortcut.

Accordingly, if the user desires to input a title, the user selects one of the consonant buttons 110 indicating the user and the preview button 180 selected by the consonant button 110, .

In the case of inputting the shorthand, the user can input the shuffle button 110 by selecting the consonant button 110 once and pressing the preview button 180 displayed by selecting the consonant button 110 for a long time.

Meanwhile, in the case of inputting a song, the consonant button 110 of the song may be selected twice to input the song, and the song may be selected by pressing and holding the preview button 180 displayed at this time.

Also, in the case of inputting the hearing, it is possible to select the consonant button 110 twice and to select the preview button 180 displayed at this time in order to input the hearing first. In this case, if you press the button twice, you can enter the key.

In short, the preview button 180 allows the input key to be re-entered by pressing once, and inputs a different key than the input key by depressing the button for a long time. Also, the preview button 180 can be selected so that the influence of the selection of other buttons is minimized, so that the preview button 180, the consonant button 110, and the vowel button 120 can be selected at the same time.

The matters not described above regarding the virtual keypad structure of FIG. 2 can be easily deduced from the same or described contents of the virtual keypad structure through FIG. 1, and the description will be omitted.

The alphabetic character button 210 has five alphabetic character buttons 210 and two alphabetic characters buttons 210 from the top of the keypad of the mobile terminal and three alphabetic characters from the third alphabetic character button 210, And an uppercase conversion button 220 for converting uppercase letters. Also, the arrangement order of the alphabet is to follow the QWERTY keyboard as shown in FIG. 3 (210), to arrange two consecutive alphabets in one button (for example, q and w share one button) The alphabet with a low frequency of use can be set as a sub key by representing the alphabet having a high frequency. However, since a and e are frequently used, they can be set as a single button without a subkey. Also, since both e and r are frequently used, r is separated from e and placed with z so that r can be displayed at the center of the alphabet button 210 and z at the lower right of the alphabet button 210 . In this case, I removed 'r' from 'e' and moved it to 'z' button in English keyboard layout because 1) 'e' is used frequently, so 'r' The purpose is to use the 'representative key' instead of 'sub key' (the representative key is to press the button once), and 2) to prevent the preview button being pressed excessively (er words or re frequently used in English words) )to be.

The special character change button 230 may be a button for switching from the English keypad to the special character keypad for inputting a special character displayed on the English keypad or not. In addition, the special character change button 230 may be located at the lower left of the virtual keypad structure 200.

The Korean-English conversion button 240 may be a button for switching from the Korean-language keypad to the English-language keypad. At this time, the Korean character change button 240 may be located in the same column as the special character change button 230 and may be located on the right side of the special character change button 230.

The interval button 250 may be a button for inputting a space between characters and characters. At this time, the interval button 250 may be located on the right side of the Korean-English conversion button 240 and may be located in the same column as the special character conversion button 230 and the Korean-English conversion button 240.

The delete button 260 may be a button for deleting one spelling in the English keypad, one vowel or consonant in the Korean keypad, or one character. In addition, the special character keypad may be a button for deleting one special character or a plurality of special characters. At this time, the erase button 260 may be located in the same column as the interval button 250.

The input button 270 may be a button serving as an enter key. Also, the input button 270 may be located in the same column as the erase button 270.

The preview button 280 may be a button for displaying a selected key to reduce a typo caused by a user not properly viewing the selected character because the user presses the finger when the keypad is selected. The input key may be displayed at the center of the preview button 280, and a key different from the key displayed at the center may be displayed at the upper left or upper right (if the key displayed at the center is a representative key, A subkey displays a representative key). The preview button 280 may be a selectable button. For example, in the case of a button including a plurality of keys, in the case of selecting twice, another key included in one button can be selected. Therefore, when the same character is repeatedly input, Can be used.
