The video / audio data generation unit 120 generates various data for the virtual scenarios generated in the scenario processing unit 110, for example, video and audio data related to the virtual object, and outputs the data to the scenario main output device 200 and the user device (500).

The data management unit 130 may store various data used to implement the virtual scenario.

The communication unit 140 may exchange data with devices and interfaces existing in the mixed reality experience space using various wire / wireless communication methods.

3 is a block diagram illustrating a scenario main output device according to an embodiment of the present invention. 3, a scenario main output device 200 according to an exemplary embodiment of the present invention includes a main display 210, a main speaker 220, and a communication unit 230. At least some of the elements described above may be omitted according to the embodiment.

In the mixed reality experience space, at least one main display 210 may be disposed. The main display 210 can visualize the virtual objects in the mixed reality experience space based on the image data received from the scenario operating server 100. [

The main display 210 may be a 2D screen or a 3D screen, or a device for visualizing only specific information, such as a display for signage output. The output state of a virtual object output to one of the main displays 210 can be controlled through a device capable of being simulated by a computer or the like in accordance with the intention of the planner constituting the scenario environment.

4 is a block diagram illustrating a user interface according to an embodiment of the present invention. 4, a user interface 300 according to an embodiment of the present invention includes a sensor unit 310 and a communication unit 320. At least some of the elements described above may be omitted according to the embodiment.

The sensor unit 310 may include various sensors for measuring the position of the user interface or for sensing the user's interaction. The sensor unit 310 may transmit the measured and sensed information to the scenario operating server 100 through the communication unit 320. [

The communication unit 320 may exchange data with the scenario operating server 100 using various types of wire / wireless communication methods.

5 is a block diagram illustrating a user device according to an embodiment of the present invention. 5, a user device 500 according to an exemplary embodiment of the present invention includes a user display 510, a user speaker 520, an image acquisition unit 530, an image control unit 540, a sensor unit 550 And a communication unit 560. Depending on the embodiment, at least some of the aforementioned components may be omitted.

The user display 510 can display a virtual object under the control of the image control unit 540. The user display 510 may be a physical display or a virtual screen.

The user display 510 may include a perspective optical system. If the user display 510 comprises a perspective optics, the user may view objects present on the opposite side of the user display 510 via the user display 510.

Generally, in the case of an optical system that forms a virtual image in a space, a virtual image is formed at a certain distance from the user's viewpoint. Therefore, it can be assumed that the virtual screen on which the user display 510 displays the virtual object is formed at the focal length L1 from the user's viewpoint. If the scenario main output device 200 is mixed around the user, a virtual screen (or physical screen) in which the scenario main output device displays the virtual object is formed at the focal distance L2 from the user's viewpoint can do. Here, L1 and L2 may be the same value or different values.

The stereoscopic optical system can embed a display filter (e.g., a stereoscopic filter) corresponding to each of a virtual screen formed by the scenario main output device 200 and a virtual screen formed by the user display 510 . Therefore, the perspective optical system can selectively transmit / block a plurality of input images and provide the images to a user. The display filter incorporated in the perspective optical system may be the same filter as the filter provided in each image output source. Meanwhile, the virtual screen formed by the user display 510 is determined by the structure of the perspective optical system. Thus, the focal length L1 can be controlled by adjusting the lens structure or employing an optical module having a variable focus, such as a liquid lens.

The user speaker 520 may provide a voice to the user based on voice data received from the scenario operating server 100. [

The image acquisition unit 530 may include a camera module and may acquire image information of the user's surroundings. The obtained image information of the user's vicinity is transmitted to the scenario operating server 100 and can be used as information for interaction with the virtual object.

The image controller 540 receives the image data from the scenario operating server 100 and outputs the virtual object to the user display 510 based on the received image data. In outputting the virtual object to the user display 510, the image controller 540 can adjust the position of the image based on the 6-degree-of-freedom information received from the sensor unit 550. Accordingly, an accurate three-dimensional image can be output to the user display 510.

The sensor unit 550 may include an acceleration sensor, a gyro sensor, and the like, and may acquire 6 degrees of freedom (6 DeFrees of Freedom) information of the user in real time. The acquired 6-degree-of-freedom information may be transmitted to the image controller 540.

The communication unit 560 can exchange data with the scenario operating server 100 using various wire / wireless communication methods.

6 and 7 are illustrations for explaining a mixed reality experience space for virtual shooting training according to an embodiment of the present invention.

Conventional shooting training (or game) involves visualizing a virtual target on a small number of image screens disposed on the front side of the user, and allowing a user, who is located remotely from the image screen, to shoot a virtual target with a weapon .

In the embodiments of the present invention, a space capable of expressing a virtual target can be extended to a space outside the screen. For example, N screens technology can be used to implement multiple screens within a mixed reality experience space. In addition, each of the users U1, U2, U3 may wear a user device, for example an HMD or an EGD. As described above, the 6DOF information of the user measured at the user device can be transmitted to the scenario operating server 100, whereby the scenario operating server 100 can calculate the 6DOF information of the user device and the position of the scenario main output device And transmit the image to be displayed on the virtual screen formed by the user device 500 to the user device 500 in consideration of the user.

Thus, the users U1 and U2 can see through the user device a virtual target that can not be output to the screen formed by the scenario main output device 200. [

It is assumed that the target T3 being visible on the main display 210 approaches the body of the user U3 and a collision occurs. In this case, it is more realistic and natural to visualize the target T3 on the display of the user device worn by the user U3, rather than visualizing the target T3 on the main display 210. [ For this, the focal lengths L1 and L2 described above can be used. For example, the target T3 may be output to the user display 510 when the position to output the target T3 is closer to the focal length L1 than the focal length L2. Conversely, when the position to output the target T3 is closer to the focal distance L2 than the focal distance L1, the target T3 may be output to the main display 210. [

On the other hand, it is assumed that users U2 and U3 interact with virtual targets using a real user interface (for example, a real model rifle). At this time, the image corresponding to the user's hand can be acquired through the image acquisition unit (or the sensor for extracting the depth information) built in the user device worn by the users U2 and U3, Can be transmitted to the scenario operating server. Accordingly, the scenario operating server can overlap and visualize a virtual user interface (e.g., a space laser gun) at the location of the real user interface used by the users U2 and U3. Similarly, for a user U1 using a real user interface with a built-in bare hand or switch or the like, a virtual user interface (e.g., a space laser gun) Can be superimposed and visualized.

Since the virtual user interface is also controlled by computer simulation, the result of the interaction between the virtual weapon and the virtual target (e.g., whether the target is hitting) can be expressed. In addition, natural voice output can be performed based on the position of the user device existing in the mixed reality experience space and the position of the main speaker. The location of the user device may be obtained from a sensor mounted on the user device, and the location of the main speaker may be provided by the system operator. The scenario operating server can control the channel and volume of each speaker in consideration of the positions of the speakers located in the mixed reality experience space, thereby realizing a natural sound output.

The embodiments of the invention described above may be implemented in any of a variety of ways. For example, embodiments of the present invention may be implemented using hardware, software, or a combination thereof. When implemented in software, it may be implemented as software running on one or more processors using various operating systems or platforms. Additionally, such software may be written using any of a number of suitable programming languages, and may also be compiled into machine code or intermediate code executable in a framework or virtual machine.

Also, when embodiments of the present invention are implemented on one or more processors, one or more programs for carrying out the methods of implementing the various embodiments of the invention discussed above may be stored on a processor readable medium (e.g., memory, A floppy disk, a hard disk, a compact disk, an optical disk, a magnetic tape, or the like).
