Description

Apparatus and method for implementing movement of virtual objects using 3 DOF controllers {APPARATUS AND METHOD FOR MAKING MOVEMENT OF VERTUAL OBJECT USING 3 DOF CONTROLLER}

Embodiments disclosed herein relate to a device for implementing a motion of a virtual object and a method for implementing the motion of a virtual object, and more particularly, to a virtual object in a three-dimensional virtual reality using a three degree of freedom controller capable of measuring two-dimensional positions. An apparatus and method for implementing the movement of the.

As hardware devices such as HMD (Head Mounted Display) are popularized along with 3D graphics technology, services using virtual reality or augmented reality technology are also becoming more diverse. Particularly, the population enjoying leisure activities such as games and sports through virtual reality is increasing, and as the technology related to virtual reality is gradually developed, the population is expected to increase more explosively.

On the other hand, in relation to the virtual reality technology, in order for the user to interact with the virtual environment, not only the change in the virtual environment must be recognized by the five senses, but also the user's behavior is influenced within the virtual environment. Should give. To this end, interface technology for interaction between virtual reality and a user is required. In particular, in order to implement a virtual reality service such as a game or sports, a controller for detecting a user's movement so that the user's action, for example, the user's hand movement is reflected in the virtual reality, and transmitting the same to the virtual reality system is required.

These controllers use sensors to detect movement caused by user actions. The sensors can detect the position, speed, acceleration, direction of rotation or speed of the controller. Specifically, such a controller may be classified into a controller having three degrees of freedom capable of measuring a two-dimensional position and a controller having six degrees of freedom capable of measuring a three-dimensional position. The six-degree of freedom controller can measure the position of the controller more precisely because it can measure the position in three dimensions, but it is more complicated and the price is significantly higher than the three degree of freedom controller because the various sensors must be used in combination. there is a problem.

Although technological advances and various attempts have been made to implement virtual reality for a long time, price barriers are a big reason why virtual reality has not been popularized. The recent explosive growth in smartphone usage has led to the introduction of very inexpensive HMDs that replace displays with smartphones, resulting in lower price hurdles and the popularity of virtual reality technology. However, in order to implement 3D virtual reality, a controller having 6 degree of freedom capable of measuring position in 3D is required, and even if the HMD is inexpensively configured, the popularization of the technology is delayed because it does not solve the price problem of the controller.

Therefore, low-cost controller technology is required to enable interaction between 3D virtual reality and users.

In this regard, Korean Patent No. 10-1752595 "Control method of the smart phone controller for the user's three-dimensional position control in the virtual space" In addition to the signal detected by the gyro sensor for the user's three-dimensional position control in the virtual space Character manipulation signals input to the touch pad are separately received and used. However, such an operation method has a problem that it is very inconvenient in requiring the user to apply a delicate touch input while controlling the movement of the smartphone. In addition, character control using a touch input has a problem of impairing the sense of realism that it belongs directly to a game environment in a process of playing a game.

Therefore, there is a demand for a technology that enables interaction with a three-dimensional virtual environment with only a low-cost controller and does not impair realism in the virtual environment.

On the other hand, the controller 200 is a device for wired or wireless communication with the motion implementing apparatus 100 of the virtual object, and detects a user's input or movement and transmits the same to the motion implementing apparatus 100 of the virtual object.

Referring to FIG. 1, the apparatus 100 for implementing movement of a virtual object may include a storage 110, a communicator 120, an input / output unit 130, and a controller 140.

First, the storage 110 may store various information such as data for management of the apparatus 100 for implementing the movement of a virtual object. In addition, the storage 110 may store an application for providing a service using a virtual reality space. The storage unit 110 may store various types of information necessary to implement an image of the virtual reality space. The storage unit 110 may hold attributes or images of various graphic objects arranged in the virtual reality space and store data required for various operations for interacting with a user.

In this case, the storage unit 110 is not necessarily provided as a means for physically forming a single device within the virtual object motion embodying apparatus 100, and is detached from the virtual object motion embodying apparatus 100, or wired or wireless communication. Any other means for providing the stored data to the apparatus 100 for implementing the movement of the virtual object is sufficient.

Meanwhile, the communication unit 120 may perform wired or wireless communication with another electronic terminal or a network. To this end, the communication unit 120 may include a communication module supporting at least one of various wired and wireless communication methods. For example, the communication module may be implemented in the form of a chipset.

In this case, the wireless communication supported by the communication unit 120 may be, for example, wireless fidelity (Wi-Fi), Wi-Fi Direct, Bluetooth, UWB (Ultra Wide Band), or NFC (Near Field Communication). In addition, the wired communication supported by the communication unit 120 may be, for example, USB or High Definition Multimedia Interface (HDMI).

The communication unit 120 may communicate with the controller 200 described above to receive various information from the controller 200. In particular, the communication unit 120 may receive the two-dimensional position coordinates of the controller 200, and may also receive the direction vector of the controller 200. At this time, the communication unit 120 may periodically and continuously receive the current position coordinates and the direction vector information of the controller 200. Furthermore, the communication unit 120 may additionally receive a speed value of the controller 200.

Furthermore, the communication unit 120 may perform wired or wireless communication with other devices. For example, when the input / output unit 130 to be described later is configured as a separate physical device, the communication unit 120 performs communication with the input / output unit 130. You may.

The input / output unit 130 may receive or display information necessary for providing a game from a user. Specifically, the input / output unit 130 may include an input unit and an output unit. The input unit may include, for example, devices capable of receiving various types of user inputs such as a keyboard, a mouse, a touch screen, a camera or a microphone, and receive an input for a graphic user interface in an image displayed by the output unit. And physical devices capable of doing so. The output unit may include a display panel, a speaker or a headset.

2, an embodiment of the image P output by the input / output unit 130 is illustrated. According to FIG. 2, the input / output unit 130 may display various graphic objects included in the three-dimensional virtual reality space S and the virtual reality space S through the image P. FIG. In this case, for example, the graphic objects may include various menu objects M selected by the user to perform a predetermined function, and may include a virtual object O moving in response to the movement of the user.

In this case, the virtual object O may be a graphic object which is a control target of the controller 200 described above, and may be controlled to move together in synchronization with a movement of the controller 200 moving together according to a user's operation. For example, the virtual object O may be a graphic object configured in the shape of a user's hand as illustrated in FIG. 2, and moves to the user by moving together according to the movement of the controller 200 held in the user's hand. Allow users to perceive themselves as if they are located in the virtual reality space.

In the example as shown in FIG. 2, the input unit of the input / output unit 120 is fixed to the user's head to detect the direction of the user's head or collect information about the user's gaze direction by detecting the movement of the user's pupil. And means for doing so. Accordingly, the output unit of the input / output unit 120 may output an image of the virtual reality space configured according to the user's gaze direction.

However, the input / output unit 120 is not limited to the above-described example and may include a configuration supporting various input / output.

Meanwhile, the controller 140 controls the overall operation of the apparatus 100 for implementing the movement of the virtual object, and may include a processor such as a CPU.

According to an embodiment, the controller 140 renders an image of the virtual reality space to be displayed to the input / output unit 130 so that the user can interact with the virtual reality, but at the same time the user's user through the input / output unit 130 The image may be configured to change the image of the virtual reality space according to an input or data received from the controller 200. In particular, the controller 140 may configure the above-described image of the virtual object O based on the data received from the controller 200.

For example, as shown in FIG. 3, when the arm of the user character and the item held by the character in the virtual reality space are set to be synchronized with the movement of the controller 200 as one virtual object O, the controller ( When the position and direction of the 200 change from the A state to the B state, the controller 140 controls the arm and the item of the character, which is the virtual object O, in the A 'state corresponding to the A state of the controller 200. It can be switched to the B 'state corresponding to the B state of). To this end, the controller 140 may change the position where the virtual object O is displayed and the displayed image of the virtual object O. FIG.

In detail, the controller 140 may determine the position and blending image of the virtual object to be controlled by the controller 200 using the position coordinates and the direction vector of the controller 200. The controller 140 may arrange the determined blending image at the determined position of the virtual object so that one frame is configured and periodically repeat this to generate an animation of the virtual object. That is, the controller 140 may continuously receive data from the controller 200, generate each frame for composing the animation of the virtual object based on the received data, and compose the animation using the periodically generated frames. In this case, the virtual object image to be included in each frame may be a blending image selected by the controller 140 for the corresponding frame among a plurality of blending images previously stored for the virtual object. In addition, the position where the selected blending image is to be disposed in each frame may be a position of a virtual object that the controller 140 calculates using the data received from the controller 200.

In this case, the controller 140 may use values of two-dimensional position coordinates of the controller 200 continuously received from the controller 200 to determine the position of the virtual object.

In detail, the controller 140 determines a moving direction of the controller 200 using the values of the two-dimensional position coordinates of the controller 200, and determines the position of the virtual object to move the virtual object according to the determined moving direction.

In this case, according to an exemplary embodiment, the controller 140 may refer to the speed value of the controller 200 received from the controller 200. When the speed value of the controller 200 is less than the preset value, the controller 140 may consider that there is no movement of the controller 200 and maintain the position of the virtual object at the current position. However, when the speed value of the controller 200 is greater than or equal to a preset value, the controller 140 calculates the moving direction of the controller 200 according to the change of the two-dimensional position coordinate values of the controller 200, and the same as the calculated direction. The position of the virtual object may be determined so that the virtual object moves in the direction.

가 10 이상일 때의 컨트롤러(200)의 위치 좌표의 집합을 연산에 이용할 수 있다. Specifically, for example, the controller 140 is a speed value of the controller 200 when the preset speed value of the controller 200 is 10.

Is a set of position coordinates of the controller 200 when 10 or more can be used for calculation.

Accordingly, if the set of position coordinates of the controller 200 collected is as shown in FIG. 4, the operation may be performed as follows.

The controller 140 determines the position of the virtual object image in each frame of the virtual object animation according to the movement direction of the controller 200 determined as described above, such that the virtual object moves according to the movement of the controller 200. You can implement the image.

For example, if the position coordinate of the controller 200 moves from (-100, -100) to (100, 100), 200 is calculated by subtracting the first coordinate -100 from the last coordinate 100 for the x-axis component. Since 200 is calculated by subtracting the first coordinate -100 from the last coordinate 100 for the y-axis component, both the computed value for the x-axis component and the computed value for the y-axis component are greater than zero. Therefore, the moving direction of the controller 200 is determined to be upper right, that is ↗.

Therefore, the controller 140 may determine the display position of the virtual object to move the virtual object O in the corresponding direction.

Meanwhile, the process of selecting the blending image for the virtual object O by the controller 140 will be described in more detail. As described above, even when the controller 140 determines the position at which the virtual object O is to be displayed, the blending image of the virtual object O to be displayed at the corresponding position in each frame does not change according to the tilt of the controller 200. The animation of the virtual object O and the movement of the controller 200 may not transmit a sense of reality. Therefore, the controller 140 may select the blending image of the virtual object O for each frame so that the virtual object O may be visually recognized as the controller 200 is tilted in the same direction.

In this case, the storage unit 110 may store images of the virtual object in a state where the virtual object is inclined in a different direction in advance as a blending image of the virtual object, in which a range of corresponding inclination values is preliminarily included in each blending image. Can be matched.

In detail, the controller 140 may calculate an axis tilt value of the virtual object based on the direction vector of the controller 200 and select a blended image corresponding to the determined axis tilt value. In this case, the axis tilt value may include a horizontal axis tilt value and a vertical axis tilt value of the virtual object, and the controller 140 may calculate the horizontal axis tilt value and the vertical axis tilt value by using the direction vector of the controller and the direction vector of the virtual reality space. Can be.

In this case, the equation used to calculate the horizontal axis tilt value and the vertical axis tilt value may be set as follows, for example.

는 컨트롤러(200)의 방향벡터이며, 가상현실공간의 방향벡터인

는 각각 (-1.0,0.0,0.0),(1.0,0.0,0.0),(0.0,1.0,0.0),(0.0,-1.0,0.0)일 수 있다.

Is the direction vector of the controller 200 and is the direction vector of the virtual reality space.

May be (-1.0,0.0,0.0), (1.0,0.0,0.0), (0.0,1.0,0.0), (0.0, -1.0,0.0), respectively.

As shown in FIG. 5, when the controller 200 is inclined with respect to both the horizontal and vertical directions, as shown in FIG. 6, the virtual object O is also tilted according to the inclined direction of the controller 200. The controller 140 may calculate an axis tilt value of the virtual object O using the direction vector of the controller 200 to have a lost image.

At this time, the horizontal axis tilt value x represents the tilt value on the xy plane of the virtual object O, and the vertical axis tilt value y represents the tilt value on the yz plane of the virtual object O.

Referring to FIGS. 5 and 6, in response to the controller 200 ′ in a dotted line, when the blade ends of the sword objects of the virtual object O ′ are arranged to face forward, the controller 200 in a solid line is shown. As shown in FIG. 6, when the tilt direction is approximately rightward with respect to the horizontal axis and upwardly with respect to the vertical axis, the virtual object O is disposed so that the edge of the blade is slightly inclined relatively to the right, but the edge of the blade is directed upward rather than forward. Can be.

As such, the controller 140 may calculate an inclination value of the horizontal axis and the vertical axis in order to reflect the inclined direction of the controller 200 to the virtual object O as it is, and select a blending image of the prestored virtual object corresponding thereto. . In this case, as described above, for each blended image, ranges of respective horizontal and vertical axis tilt values corresponding to the slope indicated by the corresponding image may be matched in advance. Accordingly, the controller 140 may select a blended image that is previously matched to a range including the calculated tilt value.

는 각각 0.623, 0.377. 0.5, 0.5로 산출된다. Referring to the axis tilt calculation process of the controller 140 with a specific example, when the direction vector of the controller 200 is (0.4, 0.0, 0.9),

Are 0.623 and 0.377, respectively. It is calculated as 0.5 and 0.5.

Accordingly, the horizontal axis tilt value may be calculated as 0.246, and the vertical axis tilt value may be calculated as 0.

In this case, the virtual object O may be rotated to the right and may appear to be not rotated on the vertical axis.

As described above, the apparatus 100 for implementing the movement of the virtual object generates each frame constituting the animation, and blends the blended image of the position where the virtual object O is to be arranged in each frame and the virtual object O to be arranged in each frame. The positional coordinates and the direction vectors of the three degree of freedom controller 200 are used for the determination.

Accordingly, the movement of the controller 200 may be synchronized with the virtual object in the three-dimensional virtual reality space as it is.

Next, a method of implementing a motion of a virtual object according to embodiments will be described with reference to FIG. 7. 7 is a flowchart illustrating a method of implementing a motion of a virtual object. The motion implementation method of the virtual object according to the embodiments shown in FIG. 7 includes steps that are processed in time series in the motion implementation apparatus 100 of the virtual object shown in FIG. 1. Therefore, even if omitted below, the above descriptions regarding the apparatus 100 for implementing the motion of the virtual object illustrated in FIG. 1 may also be applied to the method for implementing the motion of the virtual object according to the embodiments shown in FIGS. 9 to 12. Can be applied.

Referring to FIG. 7, the apparatus 100 for realizing motion of a virtual object may continuously receive information about a 2D position coordinate and a direction vector of the controller 200 (S710). In this case, the apparatus 100 for implementing the motion of the virtual object may additionally receive speed information of the controller 200.

In operation S720, the apparatus 100 for implementing movement of a virtual object may calculate a moving direction of the controller 200 using the position coordinates of the controller 200. The formula used at this time is as described above. It is a matter of course that the direction of movement may be determined in more detail than illustrated.

Subsequently, the apparatus 100 for implementing the movement of the virtual object may determine a position at which the virtual object is to be displayed such that the virtual object moves in the same direction as the determined movement direction of the controller 200 (S730). In this case, the position at which the virtual object is to be displayed may be determined as three-dimensional coordinates in the three-dimensional virtual reality space.

Meanwhile, in operation S720 and S730, the apparatus 100 for implementing the motion of the virtual object may additionally consider the speed value of the controller 200 and may not perform a position operation when the speed value is less than a preset value. .

On the other hand, before and after the parallel or serially in step S720 and S730 described above, the apparatus 100 for implementing the movement of the virtual object calculates the axis tilt value of the virtual object O by using the direction vector of the controller 200. can do. At this time, the axis tilt value may be calculated separately for the horizontal axis and the vertical axis, and the equation used is as described above. However, the formula for calculating the axis tilt value is only one embodiment, and any formula may be used as long as the formula for substantially synchronizing the tilt direction and the degree of tilt of the controller 200 with the virtual object.

Subsequently, the apparatus 100 for implementing the motion of the virtual object may determine the blended image of the virtual object based on the axis tilt value (S750). In this case, the apparatus 100 for implementing the motion of the virtual object may store a plurality of blending images representing the state in which the virtual object is inclined in different directions, and one of the pre-stored images may be selected in operation S750.

When both S720 and S730 and S740 and S740 are performed, the apparatus 100 for implementing the movement of the virtual object arranges the blending image selected in S740 and S740 at the position of the virtual object determined by performing the S720 and S730 steps. In operation S760, an animation of the virtual object may be configured by using the plurality of frames generated by repeatedly performing this process.
