It is assumed that when an input is made through the virtual keyboard, an event in which the speed of the car increases more rapidly is executed.

At this time, the command table holding unit 122 may store and maintain a plurality of predetermined character sets and an instruction table in which control event commands corresponding to the plurality of selected character sets are recorded.

Regarding this, information may be recorded in the command table as shown in Table 1 below.

A plurality of selected character sets Control event command POWER-UP! Control event command 1 POWER-DOWN! Control event command 2 CHANGE Control Event Command 3 ... ...

At this time, if a selection input for a character set called "POWER-UP!" Is received from the plurality of selected character sets by the user, the character display unit 111 displays a message "POWER-UP ! "Can be displayed on the first point 211 on the touch screen.

Here, each of the characters included in the character set "POWER-UP!" May be assigned an order number associated with the order to be input to the touch-screen electronic device 110.

2, it is assumed that the characters constituting "POWER-UP!" Are to be sequentially inputted from the left to the right in the touch-screen electronic device 110, Quot ;, and the last "!" Is assigned the sequence number "9 ".

When the character set "POWER-UP!" Is displayed at the first point 211 on the touch screen, the virtual keyboard display unit 112 displays a plurality of keypads (each of the plurality of keypads includes a touch- 110) is allocated to the virtual keyboard 218 to display the virtual keyboard 218 at the second point on the touch screen.

At this time, the coincidence judging unit 113 judges whether or not the character corresponding to each character constituting the character set "POWER-UP! &Quot; is selected in accordance with the order assigned to each character constituting" POWER-UP! Quot ;, one by one through the keyboard 218, it is possible to judge whether or not the characters inputted one by one by the user coincide with the letters "POWER-UP! &Quot;, respectively.

According to an embodiment of the present invention, the coincidence determining unit 113 may include a keypad check unit 115, a character recognition area generation unit 116, a detection determination unit 117, and an input character correction recognition unit 118 .

When the predetermined first character among the characters constituting the character set of "POWER-UP! &Quot; is the character of the sequence number to be inputted to the touch-screen electronic device 110, the keypad check unit 115 determines that the virtual keyboard 218 ) Of the plurality of keypads included in the first keypad.

2, as the character "P" and the character "O" are already input by the user among the characters constituting the character set "POWER-UP!", The " If the character " W "(212) is the first character to be input to the touchscreen electronic device 110 in this turn, the keypad validator (115) Quot; W "(212) of the first keypad (215) to which the first character is assigned.

At this time, the character recognition area generation unit 116 can generate a virtual predetermined character recognition area 216 around the first keypad 215.

According to an embodiment of the present invention, the character recognition area generation unit 116 displays a virtual selected character recognition area 216 on the touch screen, thereby allowing the user to select a virtual predetermined character recognition area 216, The touch input can be induced to apply the touch input.

Then, when the first touch input 217 for inputting the first character "W" 212 is applied to the touch screen by the user, the detection determination unit 117 outputs the first touch input 217, It is possible to determine whether or not it is detected within the virtual selected character recognition area 216. [

If it is determined that the first touch input 217 is sensed in the virtual predetermined character recognition area 216, the input character correction recognizing unit 118 recognizes that the character inputted according to the first touch input 217 Quot; W "(212) matches the first character.

If it is determined by the coincidence determining unit 113 that the character input according to the first touch input 217 coincides with the first character "W" (212), the animation display unit 114 displays, Quot; W "(212) on the first character can be displayed.

In this regard, if the character input by the user is determined to correspond to the first character of "W" (212), the animation display 114 displays "POWER Quot; W "(212) by displaying an animation of changing the color of the first character from white to black among the characters constituting the character set " -UP!" It is possible to know that the first character is correctly input.

In this way, the coincidence determining unit 113 according to the present invention generates a virtual predetermined character recognition area 216 on the virtual keyboard 218 for each of the characters constituting the character set "POWER-UP!" And judges whether or not the touch input is applied in the virtual selected character recognition area 216 to determine whether or not the characters inputted by the user coincide with the characters constituting the character set "POWER-UP!" Can be determined.

Accordingly, in order for the user to input characters constituting the character set "POWER-UP!", The touch input is not applied to the keypad to which the corresponding character is assigned, It is determined that the character is correctly input in the touch-screen electronic device 110, so that when the character input should proceed rapidly in a game or the like, the user can input the desired character without error without any error.

At this time, according to an embodiment of the present invention, the coincidence judging unit 113 judges whether or not each of the plurality of characters and each of the plurality of predetermined character recognition areas corresponding to the plurality of characters, And a ratio table holding unit 119 for storing and holding the recorded ratio table.

Regarding this, in the above ratio table, information as shown in Table 2 below may be recorded.

Multiple characters enlargement/ Reduction ratio  value P 0.7 times O 1.4 times W 1.1 times ... ...

At this time, the character recognition area generation unit 116 generates a character recognition area in which the first character 'W' 212 is input to the touch screen electronic device 110, 215), a virtual selected character recognition area 216 is generated around the first keypad 215, and a character string corresponding to the first character "W" (212) 1 magnification ratio value "1.1 times" and determines the virtual predetermined character recognition area 216 generated around the first keypad 215 according to the first enlargement / reduction ratio value "1.1 times" Can be enlarged.

On the other hand, as the character recognition area generation unit 116 becomes the order in which the character "O" is to be input to the touch-screen electronic device 110, When the confirmation of the keypad 220 is completed, a virtual selected character recognition area 219 is generated around the second keypad 220, and a second enlarged / reduced character recognition area 219 corresponding to the character "O "Quot; 1.4 times "as the reduction ratio value and enlarge the virtual predetermined character recognition area 219 generated based on the second keypad 220 according to the second enlargement / reduction ratio value" 1.4 times & have.

In this way, the coincidence judging unit 113 holds the ratio table in which a predetermined enlargement / reduction ratio value is recorded in consideration of possibility of occurrence of mischaracterization of each character with respect to a plurality of characters, It is possible to adjust the size of the virtual predetermined character recognition area according to the type of characters to be input so that the user can input each character included in the character set displayed on the first point 211 on the touch screen more easily .

According to an embodiment of the present invention, the coincidence determining unit 113 may further include a symbol checking unit 120 and a symbol matching determining unit 121. [

The symbol check unit 120 checks whether or not a character other than a letter is included among the characters constituting the character set "POWER-UP!".

In the "POWER-UP!", Since "-" 213 and "!" 214 exist as symbols other than letters, the symbol check unit 120 checks each character Quot; - " 213 and "!" 214 exist as symbols other than letters.

Thereafter, the symbol match determiner 121 determines that the characters corresponding to the characters "-" 213 and "!" 214 are to be input on the touch screen electronic device 110, Even if characters corresponding to "-" 213 and "!" 214 are not inputted through the keyboard 218, characters matching both of "-" 213 and "!" .

That is, when the symbol matching determination unit 121 determines that the characters corresponding to "-" and "!" 214 are to be input on the touch screen electronic device 110, 213 and "214 " are normally entered on the touch screen electronic device 110 by the user even if" - " 213 and " , Even if the user correctly inputs only the letter "POWERUP" among the characters included in the character set "POWER-UP!", It is determined that the entire character "POWER-UP! .

In this manner, if it is determined by the coincidence determining unit 113 that all the characters included in the character set "POWER-UP!" By the user are normally input on the touch-screen electronic device 110, the event executing unit 123) can extract a "control event command 1" corresponding to the character set "POWER-UP!" From the command table shown in Table 1 and execute a control event according to the extracted "control event command 1".

That is, when an application related to a predetermined car game is being driven on the touch-screen electronic device 110 and a "control event command 1" is a control event command that increases the speed of the car more rapidly, When all the characters included in the character set "POWER-UP!" Have been input by the user, the event execution unit 123 extracts "control event command 1" from the command table, The speed of the automobile can be increased more rapidly.

As a result, the touch screen electronic device 110 according to the present invention does not allow a user to input a touch input on a keypad corresponding to a related character in a game or a language learning program in which a user has to perform character input using a virtual keyboard The convenience of the user can be obtained by determining the intention of the user and judging that the corresponding character is input on the touch screen electronic device 110. When the user inputs the same character as the character displayed on the touch screen , A specific control event is executed, thereby giving a fun to the user, and at the same time, helping the user to improve their language ability.

3 is a flowchart illustrating an operation method of a touch screen electronic device according to an exemplary embodiment of the present invention.

In step S310, a character set consisting of at least one character that is to be input to the touch screen electronic device by the user (each of the at least one character is assigned an order number associated with a sequence to be input to the touch screen electronic device) To the first point on the touch screen.
