As described above, the virtual pad providing apparatus 10 can be implemented in the form of either an electronic terminal or a server-client system. When the virtual pad providing apparatus 10 is implemented as a server-client system, Some of the parts can be performed only on the server or only on the client.

The virtual pad providing apparatus 10 may include an input / output unit 110, a control unit 120, a communication unit 130, and a memory 140 according to an embodiment of the present invention.

The input / output unit 110 may include an input unit for receiving an input from a user, and an output unit for displaying information such as a result of performing a task or a state of the virtual pad providing apparatus 10. [ For example, the input / output unit 110 may include an operation panel for receiving user input and a display panel for displaying a screen.

Specifically, the input unit may include devices capable of receiving various types of user input such as a keyboard, a physical button, a touch screen, a camera or a microphone. Also, the output unit may include a display panel or a speaker. However, the present invention is not limited to this, and the input / output unit 110 may include various input / output support structures.

The control unit 120 controls the overall operation of the virtual pad providing apparatus 10 and may include a processor such as a CPU. The control unit 120 may control other components included in the virtual pad providing apparatus 10 to perform an operation corresponding to a user input received through the input /

For example, the control unit 120 may execute a program stored in the memory 140, read a file stored in the memory 140, or store a new file in the memory 140. [

The control unit 120 may provide a virtual pad for controlling an object located in a game space by identifying a control direction of the user based on a relative position with respect to a touch input at a position of the touch screen as a reference point.

For example, the control unit 120 may provide a virtual pad at a position where the touch input of the first user is detected on the touch screen.

At this time, the virtual pad may include a reference point, which is a reference position for acquiring the control direction according to the position where the touch input is generated, and the virtual pad providing apparatus 10 may include a virtual pad And the control direction corresponding to the touch input of the user can be identified.

According to one embodiment, the control unit 120 may move the viewpoint to the game space when the moving direction of the object is changed based on the touch input generated in the virtual pad.

That is, the controller 120 can maintain the viewpoint of the game space in the same direction as the moving direction of the object, and can move the viewpoint to the game space in the moving direction of the changed object when the moving direction of the object is changed.

For example, when the user moves the moving direction of the object by performing a touch input to the right of the virtual pad to move the moving direction of the moving object to the right, the controller 120 moves the moving object The viewpoint for the space can be rotated 90 degrees clockwise to move the viewpoint to the game space in the same direction as the movement direction of the object.

According to another embodiment, the controller 120 may move the viewpoint to the game space according to predetermined conditions.

For example, when the terrain or object of the game space obscures the object, the control unit 120 can move the viewpoint to the game space regardless of the touch input of the user.

For example, the control unit 120 can move the viewpoint to the game space when a specific event occurs according to the setting of the game even if the terrain of the game space or the object does not block the object.

According to the above-described embodiment, the controller 120 can control the virtual pad so that the moving direction of the object is maintained even when the viewpoint of the game space is changed.

For example, when the user touches the right side of the virtual pad and moves forward to the right, the controller 120 can rotate the viewpoint on the game space in the same direction as the moving direction of the object moving to the right .

At this time, the object advances at the changed point, but the user holds the touch of the virtual pad in the right direction, and the object moves to the right. Accordingly, the controller 120 controls the virtual pad according to the change of the viewpoint of the virtual space, thereby preventing the moving direction of the object from being further changed even if the position of the touch input of the user is maintained.

For this, the controller 120 can adjust the relative position between the touch input and the reference point of the virtual pad according to the movement of the viewpoint.

According to the embodiment, the control unit 120 may move the reference point of the virtual pad in the direction opposite to the moving direction of the viewpoint at an angle corresponding to the angle of rotation of the viewpoint with respect to the game space.

For example, when the viewpoint of the game space moves clockwise by 90 degrees, the control unit 120 moves the reference point of the virtual pad counterclockwise at an angle equal to the moving angle of the viewpoint around the position of the user's touch input And the direction of the user's touch input may be the same direction as the moving direction of the object based on the moved reference point.

The control unit 120 may change the position of the reference point of the virtual pad to change the position of the user relative to the touch point of the virtual pad, thereby changing the control signal corresponding to the user's touch input .

In this way, when the viewpoint of the game space is changed, the controller 120 can provide a virtual pad in which the moving direction of the character is controlled according to the intention of the user without changing the touch input to the virtual pad.

According to the embodiment, the controller 120 can adaptively change the position of the virtual pad according to the position of the touch input of the user. When the virtual pad is moved in accordance with the change of the viewpoint on the game space, Can be moved to a predetermined position and provided to the user.

For example, the controller 120 can move the virtual pad to the center of the touch screen according to the position of the touch input of the user, and when the game is forced to move to the game space, 120 may move the virtual pad to a predetermined position.

According to the embodiment, when the reference point of the virtual pad is moved based on the area of the virtual pad, the controller 120 can change the distance between the reference point of the virtual pad and the touch input.

At this time, the control unit 120 may detect whether the area of the virtual pad is located within the touch screen while moving the reference point of the virtual pad in the direction opposite to the direction of movement of the viewpoint.

When the virtual pad area moves away from the touch screen as the virtual pad reference point moves, the control unit 120 can move the virtual pad reference point while reducing the distance between the virtual pad reference point and the touch input.

For example, the control unit 120 may move the reference point while reducing the distance between the reference point of the virtual pad and the touch input so that the area of the virtual pad does not deviate from the boundary of the touch screen.

Or when the virtual pad area is moved out of the touch screen as the virtual pad reference point is moved, the controller 120 may reduce the size of the area of the virtual pad according to the embodiment.

For example, when moving the reference point of the virtual pad, if the area of the virtual pad is out of the boundary of the touch screen, the controller 120 may reduce the size of the area of the virtual pad so that the distance between the reference point of the virtual pad and the touch input is maintained have.

Meanwhile, the controller 120 may control the rotation angle of the reference point of the virtual pad based on the position of the changed touch input when the position change of the touch input of the virtual pad is detected when the viewpoint of the game space is moved.

That is, the controller 120 can detect the change of the input position of the virtual pad according to the movement of the viewpoint, and can rotate the reference point of the virtual pad by reflecting the angle between the position of the touch input before the change and the position of the changed touch input. The angle can be adjusted,

For example, if the user moves the position of the touch input on the virtual pad in the counterclockwise direction by 40 degrees while the game environment is moved 90 degrees clockwise, the control unit 120 sets the reference point of the virtual pad It is not rotated by 90 degrees which is the rotation angle of the viewpoint but can be rotated by 50 degrees except 40 degrees which is the rotation angle according to the change of the position of the touch input of the user.

Accordingly, even when the user changes the touch input of the virtual pad according to the viewpoint change in the game space, the virtual pad can be adaptively controlled according to the change amount of the corresponding touch input, thereby more accurately reflecting the user's intention .

Meanwhile, the communication unit 130 can perform wired / wireless communication with other devices or networks. To this end, the communication unit 130 may include a communication module supporting at least one of various wired / wireless communication methods. For example, the communication module may be implemented in the form of a chipset.

The wireless communication supported by the communication unit 130 may be Wi-Fi (Wireless Fidelity), Wi-Fi Direct, Bluetooth, UWB (Ultra Wide Band), NFC (Near Field Communication), or the like. The wired communication supported by the communication unit 130 may be, for example, USB or High Definition Multimedia Interface (HDMI).

Various types of data such as files, applications, programs, and the like may be installed and stored in the memory 140. The control unit 120 may access the data stored in the memory 140 and use the data or store the new data in the memory 140. [ Also, the control unit 120 may execute a program installed in the memory 140. [ Referring to FIG. 1, a program for performing a virtual pad providing method may be installed in the memory 140.
