FIG. 2 is a block diagram illustrating an internal configuration of a keyboard control system in an embodiment of the present invention, and FIG. 3 is a flowchart illustrating a keyboard control method in an embodiment of the present invention.

2, the keyboard control system 200 according to the present embodiment may include a processor 210, a bus 220, a network interface 230, a memory 240, and a database 250 . The memory 240 may include an operating system 241 and a keyboard control routine 242. The processor 210 may include a searching unit 211, a classifying unit 212, and a display unit 213. [ In other embodiments, the keyboard control system 200 may include more components than the components of FIG.

The memory 240 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. In addition, the memory 240 may store program codes for the operating system 241 and the keyboard control routine 242. [ These software components may be loaded from a computer readable recording medium separate from the memory 240 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 240 via the network interface 230 rather than from a computer readable recording medium.

The bus 220 may enable communication and data transfer between components of the keyboard control system 200. [ The bus 220 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or other suitable communication technology.

The network interface 230 may be a computer hardware component for connecting the keyboard control system 200 to a computer network. The network interface 230 may connect the keyboard control system 200 to a computer network via a wireless or wired connection.

The database 250 is a word database (DB) for storing and maintaining lexical information, which can be utilized to classify valid characters and effective characters for an input character string. At this time, not only dictionary DB but also all word DBs applied to speech recognition, word learning, autocomplete, etc. can be utilized as database 250. Although FIG. 2 shows that the database 250 is built and included in the keyboard control system 200, it is also possible to exist as an external database built on a different system. Here, the external database may include, in addition to the database included in the keyboard control system 200, a database included in another function (for example, a dictionary function, a voice recognition function, etc.) that can be interlocked with the keyboard control system 200 in the local environment It may mean a database as well as a database built on the Internet. For example, if the keyboard control system 200 is implemented as a terminal-specific application, a word DB stored on the user terminal or a word DB accessible through online can be used as the database 250. [

The processor 210 may be configured to process instructions of a computer program by performing input / output operations of a basic arithmetic, logic, and keyboard control system 200. The instructions may be provided by the memory 240 or the network interface 230 and to the processor 210 via the bus 220. The processor 210 may be configured to execute the program code for the searching unit 211, the classifying unit 212, and the display unit 213. [ Such program code may be stored in a recording device such as memory 240. [

The search unit 211, the classifying unit 212, and the display unit 213 may be configured to perform the steps S310 to S330 of FIG.

In step S310, the search unit 211 may search for a word including an input character using a word DB with respect to a character (input string) being input through the keyboard by the user. At this time, the search unit 211 can search for words starting with the input string in the word DB. For example, as shown in FIG. 4, when the user inputs 'A', the user can search the word DB using the input string 'A' as a search word, and a word list beginning with 'A' can be obtained at this time. The search unit 211 can perform a real-time search of the word DB while the search word is updated each time a phoneme is added according to a continuous character input by the user. For example, when a user continuously inputs the phonemes 'a', 'a', 'a', and 't', the search term is updated in the order of 'a', 'a', 'a' will be.

In addition, the search unit 211 may continuously input characters on a phoneme-by-phoneme basis, and initialize a search term for a DB search when a character spacing code or other characters are input. At this time, the character spacing code means a code that can input blank or new line characters such as space, enter, tap, shift, etc., It can mean a character that can not be combined with a syllable or word, such as a symbol (~,!, @, Etc.) or a number. For example, when 'furniture' is input as a continuous character input from a user, 'furniture' is searched for as a search word, while 'furniture' including a space is input, the search word is reset immediately after the space At this time, the keyboard is provided in the default state.) The word DB can be searched by using the character string 'i' as a search word after the space.

The search unit 211 can determine a search term for the DB search based on the position of the cursor appearing in the input string. For example, the search unit 211 can search a word DB by using a character string from the input character string to the immediately preceding cursor as a search word. 5, when the user inputs 'Korean Min' into the input window 520 using the keyboard 510, a cursor 521 is positioned after the last character, and 'Korean Min' is used as a search term If the user moves the position of the cursor 521 between 'Korean' and 'Min' using a direction key or the like, the user can search the word DB again using 'Korean' as a search term.

In step S320, the classification unit 212 may classify the valid character and the effective character for the input character string using the word list acquired through the search in step S310. For example, the classifying unit 212 extracts characters that can appear after the input string from the words included in the word list, and then extracts the extracted characters as effective characters and the remaining characters as the effective characters Can be classified.

In step S330, the display unit 213 can display characters constituting the keyboard by dividing them into valid characters and effective characters. At this time, the display unit 213 can constitute a key board in which a highlighting effect is applied to valid characters and an effective character is shrunk. For example, as shown in FIG. 6, the display unit 213 displays character buttons corresponding to valid characters among the characters constituting the keyboard 610 with a color or brightness different from those of the effective characters, It can be displayed with better visibility than color or brightness. As another example, the display unit 213 controls the size (or character size) of the character button corresponding to the valid character among the characters constituting the keyboard by adjusting the button size (or character size) of the keyboard to be larger than the effective character can do. As shown in FIG. 7, the display unit 213 may include a character button corresponding to a valid character string as a separate layer 730, and then a valid character key board 730 composed of only valid characters may be used as an existing character string Can be displayed on the keyboard 710 in an overlapping manner. In addition, the display unit 213 can display different characters from the buttons of the effective character by applying various display effects such as blinking to the character buttons corresponding to the valid characters among the characters constituting the keyboard. The display unit 213 can display the keyboard in a default state without distinguishing between valid characters and effective characters when a character spacing code or other characters are input during character input. In other words, when a continuous character string is displayed, a character string in which a valid character and an effective character are distinguished is displayed, and when a character spacing code or other character is input, all the characters of the character string can be in a valid input state.

As described above, in the keyboard control system and keyboard control method according to the present invention, the button color of a valid character that follows the input character string may be displayed differently from the effective character, or the touch range of the effective character may be widened and the touch range of the effective character may be reduced The effective character and the effective character are distinguished from each other by the method of FIG. 4, thereby helping the unfamiliar user to find the next input character more quickly and reducing the input of misspell.

8 to 10 are exemplary diagrams showing application examples of the keyboard control system according to the present invention.

8 and 9 illustrate a keyboard layout change in the process of inputting 'Korea'. The keyboard layout control system is a character string that can be followed by 'c' for the input string 'c' based on the word DB It is possible to provide a keyboard with emphasized buttons of 'ㅛ', 'ㅐ', 'ㅔ', 'ㅗ', 'ㅓ', 'a', 'び', 'ㅠ', ' The input character string 'Sub' can provide a keyboard that emphasizes the buttons 'ㅂ', 'ㄱ', 'ㅁ', 'ㄴ', 'ㅇ' Can provide a keyboard with emphasis on the 'a' button as a letter that follows 'Korean Min-gu'. In the case where the user continuously inputs up to 'Korean Min-gu', the keyboards emphasizing the effective characters can be sequentially provided for each input string in which the phonemes are added in the order shown in Figs. 8 and 9. In this case, The user can re-supply the keyboard shown at the bottom of FIG. 8 when the cursor is moved to 'Min-goo'.

FIG. 10 illustrates a keyboard layout change in the process of inputting 'england'. The keyboard layout control system uses 'e' as a character that can be followed by 'eng' with respect to the input string 'eng' , 'r', 'y', 'u', 'i', 'o', 'a', 's', 'g', 'h', 'k' , 'I', 'c', and 'n' for the input string 'engla', followed by 'engla'.

Accordingly, in the present embodiment, it is possible to classify a character which can be followed by a user in the input of a word DB and a non-corresponding character in real time using the word DB, emphasize a character string that can be inputted, , And such a keyboard layout is applicable to all language keyboards in which syllables or words can be input in Korean or English as well as in character combinations.
