The server may be implemented as a computing device capable of communicating with an electronic terminal equipped with a client for interacting with a user via a network N, and may include a storage device capable of storing data, or a third server Quot;). ≪ / RTI >

According to an embodiment of the present invention, the input means providing apparatus 100 implemented in the form of an electronic terminal or a server-client as described above may include a touch screen capable of acquiring a touch input The virtual input means can be displayed on the touch screen so that the executed application can be controlled and the application can be controlled by acquiring the touch input generated on the displayed virtual input means as the user input.

In addition, when the application to be executed is a game, the input means providing apparatus 100 stores various information related to game progress, such as game space information, game scenario information, and game quest information, and detects and records various events occurring in the game Thereby enabling the game to progress in a time-wise manner.

Meanwhile, the input device providing apparatus 100 according to an embodiment of the present invention may include an input means display unit 110, a touch input obtaining unit 120, and a position changing unit 130.

In addition, the input means providing apparatus 100 enables communication between the internal components, that is, the input means display unit 110, the touch input obtaining unit 120, and the position changing unit 130, And a communication unit (not shown).

Meanwhile, an input means providing apparatus 100 according to an embodiment of the present invention may include an input means display unit 110. [ The input means display unit 110 may display a virtual input means having an input region for acquiring a touch input within a certain region as a user input on a touch screen.

That is, the input means display unit 110 may display an input area for acquiring a user input by displaying a virtual input means of a shape intuitively recognizable by the user on the touch screen.

For example, the input means display unit 110 may display a circle having a joystick shape in the lower left corner of the touch screen, and may indicate a range in which a circle indicating the joystick can be operated. In addition, the input means display unit 110 may display at least one input button on the lower right of the touch screen.

At this time, the position at which the virtual input means is displayed may be displayed at a predetermined position or at a position set by the user.

According to one embodiment, the input means display unit 110 may display the keypad at a position set in the application by default.

For example, the input means display unit 110 may arrange a virtual input means that forms a joystick in a shooting game at a lower left side of the touch panel, and a virtual input means that shapes a button at a lower right side of the touch panel.

According to another embodiment, the input means display unit 110 can set the display position of the virtual input means from the user.

For example, when the game application is installed and executed for the first time, the input means display unit 110 may request the user to arrange the position of the joystick and the button as the virtual input means. At the position set by the user, Can be arranged.

When the position of the virtual input means is changed by the position changing unit 120, which will be described later, the input means display unit 110 can move and display the virtual input means to the changed position.

At this time, the input means display unit 110 may control the transparency of the virtual input means whose position is changed and displayed according to an embodiment.

For example, when the joystick located on the lower left of the input unit display unit 110 is moved in the center direction of the touch screen, the joystick can be displayed in a transparent state by increasing the transparency of the joystick from 40% to 90%.

For example, when the joystick positioned at the lower left of the input unit display unit 110 moves in the center direction of the touch screen and displays the joystick, the joystick's transparency can be adjusted according to the distance from the center. For example, You can lower the transparency of the joystick.

For example, when the joystick located at the lower left of the input unit 110 is displayed in the center direction of the touch screen, the input unit display unit 110 calculates the distance between the joystick position and the moved position, The transparency of the joystick can be adjusted, for example, the greater the calculated distance, the higher the transparency of the joystick.

Meanwhile, the input means providing apparatus 100 may include a touch input obtaining unit 120. The touch input obtaining unit 120 may obtain the position of the touch input sensed through the touch screen.

That is, the touch input obtaining unit 120 can obtain the position of the touch input and determine whether the touch input is within the input area of the virtual input means displayed through the input means display unit 110, and acquire the generated touch input as the user input.

For example, the joystick, which is a virtual input means displayed on the touch screen, may include a direction key for selecting a direction and a movable area for a direction key, and when a touch input is generated within an input area that is an area where the joystick is displayed, 120 can acquire the position where the touch input is generated as a user input by operating the joystick, and can reflect the acquired touch input to the application.

At this time, when the touch input is generated in a position other than the input area, the touch input obtaining unit 120 may not reflect the corresponding touch input in the application.

For example, if a touch input is generated outside the operating area of the joystick displayed on the touch screen, the touch input obtaining unit 120 may obtain the touch input, but may not reflect the input as a user input in the application, To-be-changed position changing unit 130. [

Alternatively, there may be a case where an input intended by a touch in the input area or a touch input deviates from an input area of the touch input.

For example, there may be a case where a touch is not properly performed in an input area or an input area intended for a touch in an input area, such as when a touch input is generated at an input area boundary. When the touch input is generated only at the boundary of the input area, the touch input obtaining unit 120 transmits the position located closest to the touch input as a position outside the input area to the position changing unit 130 to be described later, It can be determined that a touch input is generated at a position closest to the touch input, and the application can be notified that a user input has occurred at the corresponding position. Further, the touch input acquisition unit 120 can reflect the touch input generated in the input area during the touch input to the application as the touch input is generated across the boundary of the input area, And may transmit the position of the input to the position changing unit 130 to be described later.

In another example, there may be a case where a touch is not properly performed in an input area or an input area intended for a touch in an input area, such as when a touch input is generated at a position close to the input area. Accordingly, for example, when the touch input is generated within a predetermined distance from the input area as a touch input outside the input area, the touch input obtaining unit 120 transmits the position of the touch input to the position changing unit 130, It can be determined that a touch input is generated at a position nearest to the touch input as a position in the input area, and it can be reflected in the application that a user input has occurred at the corresponding position.

If the user intends to touch input to the virtual input means as described above but the touch input is not the input region, the input means providing apparatus 100 may actively change the position of the virtual input means according to the position of the touch input So that the application can be operated according to the user's intention.

On the other hand, the input means providing apparatus 100 may include a position change unit 130. The position changing unit 130 may change the position of the virtual input means based on the position of the obtained touch input.

That is, when the position of the touch input of the user is out of the input area, the position changing unit 130 may change the position of the virtual input means to the position where the touch input of the user occurs.

For this, the position changing unit 130 may calculate the distance between the position of the virtual input means and the position where the touch input is generated, and calculate the position of the touch input based on the position of the virtual input means.

For example, the position changing unit 130 may calculate the distance and the direction from the existing virtual input means to the position where the touch input is generated by using the X-axis and Y-axis distance difference of the touch screen.

The position changing unit 130 can determine a weight for calculating a position to be changed of the virtual input means based on at least one of the calculated distance and direction, thereby actively controlling the degree of position change of the virtual input means can do.

In this case, the position changing unit 130 may determine the weight based on the direction of the touch input based on the position of the virtual input unit.

For example, when the virtual input means is located at the lower left of the touch screen and the position of the touch input occurs in the center direction of the touch screen based on the virtual input means, the position change unit 130 may determine the weight to be less than 1 have.

For example, if the position of the touch input occurs in the corner direction of the touch screen based on the virtual input means, the position change unit 130 may determine the weight value to be 1 or more.

According to another embodiment of determining the weight, the position changing unit 130 may determine the weight in inverse proportion to the distance from the virtual input means to the position of the touch input.

For example, when the position of the touch input is located in the center direction of the touch screen based on the virtual input means and the distance is 0.5 cm, the position changing unit 130 can determine the weight to be 0.8, , The position changing unit 130 may determine the weight to be 0.5.

Accordingly, the input means providing unit 100 provides a virtual input means at a position where a touch input of a user occurs, restricts the virtual input means from changing the position in the center direction of the touch screen through the weight, The position of the virtual input means may be restricted from being shifted from one area of the touch screen to the center of the touch screen by reflecting the position change in the corner direction of the screen.

On the other hand, according to another embodiment for determining the weight, the position changing unit 130 may extract a change pattern of the position of the touch input based on the position at which the touch input is generated, and determine the weight based on the extracted change pattern have.

For example, the position changing unit 130 can group change positions where a plurality of touch inputs are generated to extract a change pattern, and based on the extracted change pattern, the touch input of the user is mainly directed toward the center of the touch screen The position change unit 130 may determine that the weight value reflected in the separation distance of the virtual input means is less than 1.

By thus determining the changing position of the virtual input means on the basis of the pattern of the touch input by the user, it is possible to prevent the virtual input means from being tilted toward the center of the touch screen and to provide the user with convenience of using the virtual input means within a certain position have.

According to another embodiment for determining the weight, the location change unit 130 may determine the weight differently based on the screen configuration output to the touch screen.

That is, when the position of the virtual input means is changed according to the position of the touch input of the user, the position changing unit 130 may determine the weight according to the screen configuration output on the touch screen.

For example, when the character of the game screen displayed on the touch screen moves only at the bottom of the screen, the position change unit 130 moves the position of the user's touch input toward the center of the touch screen based on the virtual input means, Even if it is 1 cm, the weight can be determined as 0.9 instead of 0.5.

Then, the position changing unit 130 may determine the changed position of the virtual input means by reflecting the weight determined as described above to the separation distance between the position of the virtual input means and the position of the touch input.

Accordingly, the input means providing apparatus 100 changes the position where the virtual input means is adaptively provided based on the position of the user's touch input, prevents the position of the virtual input means from being shifted to the center of the touch screen, It is possible to prevent the game screen displayed on the touch screen from being obscured and allow the user to operate the game while viewing the game screen more comfortably.

On the other hand, as the position of the virtual input means is changed toward the center of the touch screen, the position changing unit 130 causes the input means display unit 110 to display the virtual input means transparently by increasing the transparency of the virtual input means displayed on the touch screen .

Further, as the virtual input means moves away from the center of the touch screen, the position change unit 130 causes the input means display unit 110 to lower the transparency of the virtual input means displayed on the touch screen so that the user can easily .

2 to 3 are flowcharts for explaining a method of providing input means according to an embodiment of the present invention.

The method of providing an input means according to the embodiment shown in FIGS. 2 to 3 includes the steps of time series processing in the input means providing apparatus 100 shown in FIG. Therefore, even if omitted from the following description, the above description of the input means providing apparatus 100 shown in FIG. 1 can also be applied to the input means providing method according to the embodiment shown in FIG. 2 to FIG.

4 to 6 will be described below with reference to Figs. 2 to 3 in conjunction with Figs. 4 to 6 are diagrams for explaining a method of providing an input means according to an embodiment of the present invention and show an example of a game screen appearing on the screen of the electronic terminal in which the input means providing apparatus 100 is implemented will be.

2 is a flowchart of a method of providing input means according to an embodiment of the present invention. In operation S2001, the input means providing apparatus 100 may display a virtual input means having an input region for acquiring a touch input within a certain region as a user input on the touch screen.

For example, the input means providing apparatus 100 may display a joystick composed of a direction key and a moving area of a direction key at the lower left of the touch screen, and may provide at least one input button in the lower right of the touch screen .

Then, the input means providing apparatus 100 can acquire the position of the touch input sensed through the touch screen (S2002).

For example, the input means providing apparatus 100 may obtain coordinates corresponding to the X-axis and Y-axis positions of the touch input generated on the touch screen.

Thereafter, the input means providing apparatus 100 can change the position of the virtual input means based on the obtained position of the touch input (S2003).

To this end, the input means providing device 100 may compare the position of the virtual input device displayed in one area of the touch screen with the position of the touch input area obtained in step S2002 in step S2001.

For example, the input means providing apparatus 100 may determine whether the position of the obtained touch input is within the input area of the joystick displayed at the lower left of the touch screen.

If the position of the obtained touch input is out of the input area or the input area boundary, the input means providing device 100 can display and change the position of the displayed virtual input means.

For example, when a touch input that is out of the movable range of the joystick is generated, the input means providing apparatus 100 may display the joystick so that the center of the joystick is positioned at the position where the touch input is generated.

Hereinafter, a method of providing the virtual input means by the input means providing apparatus 100 will be described in more detail.

FIG. 3 is a diagram illustrating an example in which the input means providing apparatus 100 changes a position of a virtual input means by reflecting a weight on a distance from a position of a virtual input means to a position of a touch input according to an embodiment of the present invention, Fig.

Referring to FIG. 3, the input means providing apparatus 100 may display the virtual input means on the touch screen (S3001).

At this time, according to the embodiment, the input means providing apparatus 100 can display the virtual input means at a predetermined position in the application or input the position at which the virtual input means is displayed from the user.

4 is an exemplary diagram showing a screen in which the input means providing apparatus 100 provides virtual input means.

The input means providing apparatus 100 may display a joystick 404 and an input button 405 constituted by a direction key 402 and a movable region 403 of a direction key 402 on the touch screen 401 .

Then, the input means providing apparatus 100 can determine whether a touch input has occurred in the input area of the virtual input means (S3003)

According to one embodiment, when the touch input is generated in the input area of the virtual input means, the input means providing apparatus 100 may not change the position of the separate virtual input means.

4, when the user's finger 406 touches the direction key 402 in the movable area 403, the position of the joystick 404 may not be changed.

However, if the generated touch input is not generated within the input area of the virtual input means, the input means providing apparatus 100 may calculate the separation distance from the virtual input means to the position of the touch input (S3004).

For example, the input means providing apparatus 100 can calculate the shortest straight line distance from the virtual input means to the position of the touch input when a touch input occurs in the input region other than the input region of the virtual input means.

Then, the input means providing apparatus 100 can determine the weight according to the direction of the touch input based on the position of the virtual input means (S3005).

That is, according to one embodiment, the input means providing apparatus 100 can calculate the weight differently based on the position of the touch input with respect to the center of the touch screen.

For example, when the position of the touch input is located close to the center of the touch screen based on the position of the virtual input means, the input means providing apparatus 100 may determine that the weight is less than one.

Alternatively, for example, the input means providing apparatus 10 may determine the weight to be 1 if the position of the touch input is closer to the edge of the touch screen based on the position of the virtual input means.

At this time, according to the embodiment, the input means providing apparatus 100 may determine the size of the weight differently based on the distance to the position of the touch input based on the position of the virtual input means.

For example, when the distance from the virtual input means to the position of the touch input exceeds a predetermined distance, the input means providing apparatus 100 may further reduce the size of the weight determined based on the direction of the touch input have.

Accordingly, the virtual input means can be changed within a predetermined distance, thereby changing the position of the virtual input means within a predetermined area, and at the same time guiding the user to the touch input region.

Thereafter, the input means providing apparatus 100 may change the position of the touch input by reflecting the determined weight (S3006).

5 is a diagram illustrating an example in which a position of a virtual input means is changed by making a touch input of a user in a center direction of a touch screen.

5, when the touch input by the finger 502 is generated in the center direction of the touch screen 503, the input means providing apparatus 100 receives the touch input from the first position 501 by the finger 502 The position of the input means may be changed from the first position 501 to the second position 504 by reflecting the weight of less than 1 determined in step S3005 in the separation distance 506 to the position of the input unit.

The distance 505 from which the joystick is changed from the first position 501 to the second position 504 is greater than the distance 506 between the position of the touch input by the finger 502 and the first position 501, .

FIG. 6 is an exemplary view illustrating a state in which the position of the virtual input means is changed by making the touch input of the user in a direction opposite to the center of the touch screen.

6, when the touch input by the finger 602 is generated in the corner direction of the touch screen 603, the input means providing apparatus 100 receives the touch input from the first position 604 by the finger 602 The position of the input means can be changed from the first position 604 to the second position 601 by reflecting the weight of 1 determined through step S3005 in the separation distance 606 to the position of the first position 604.

The range 605 of movement of the joystick from the first position 604 to the second position 601 is equal to the distance 606 between the position of the touch input by the finger 602 and the first position 604 can do.

Meanwhile, according to one embodiment, the input means providing apparatus 100 can control the transparency of the virtual input means in accordance with the change of the position of the virtual input means.

For example, the input means providing apparatus 100 can increase the transparency as the position of the virtual input means moves to the center of the screen of the touch screen, and in the opposite case, the transparency can be lowered so that the user can easily recognize the position.
