[Configuration of HMD system]
The configuration of an HMD (Head-Mounted Device) system 100 will be described with reference to FIG. FIG. 1 is a diagram showing a schematic configuration of an HMD system 100 according to the present embodiment. The HMD system 100 is provided as a home system or a business system.

  The HMD system 100 includes a server 600, HMD sets 110A, 110B, 110C, 110D, an external device 700, and a network 2. Each of the HMD sets 110A, 110B, 110C, and 110D is configured to be able to communicate with the server 600 and the external device 700 via the network 2. Hereinafter, the HMD sets 110A, 110B, 110C, and 110D are collectively referred to as an HMD set 110. The number of the HMD sets 110 configuring the HMD system 100 is not limited to four, and may be three or less or five or more. The HMD set 110 includes the HMD 120, the computer 200, the HMD sensor 410, the display 430, and the controller 300. The HMD 120 includes a monitor 130, a gaze sensor 140, a first camera 150, a second camera 160, a microphone 170, and a speaker 180. Controller 300 may include a motion sensor 420.

  In one aspect, the computer 200 is connectable to the Internet and other networks 2 and can communicate with the server 600 and other computers connected to the network 2. As other computers, for example, a computer of another HMD set 110 and an external device 700 can be mentioned. In another aspect, the HMD 120 may include the sensor 190 instead of the HMD sensor 410.

  The HMD 120 may be worn on the head of the user 5 and provide a virtual space to the user 5 during operation. More specifically, HMD 120 displays a right-eye image and a left-eye image on monitor 130, respectively. When each eye of the user 5 visually recognizes each image, the user 5 can recognize the image as a three-dimensional image based on the parallax of both eyes. The HMD 120 may include any of a so-called head-mounted display having a monitor, and a head-mounted device to which a smartphone or other terminal having a monitor can be attached.

  The monitor 130 is realized, for example, as a non-transmissive display device. In one aspect, monitor 130 is disposed on the main body of HMD 120 so as to be located in front of both eyes of user 5. Therefore, when the user 5 visually recognizes the three-dimensional image displayed on the monitor 130, the user 5 can immerse in the virtual space. In one aspect, the virtual space includes, for example, a background, an object that can be operated by the user 5, and an image of a menu that can be selected by the user 5. In a certain aspect, the monitor 130 can be realized as a liquid crystal monitor or an organic EL (Electro Luminescence) monitor included in a so-called smartphone or other information display terminal.

  In another aspect, monitor 130 may be implemented as a transmissive display. In this case, the HMD 120 may be an open type such as a glasses type instead of a closed type that covers the eyes of the user 5 as illustrated in FIG. The transmissive monitor 130 may be temporarily configurable as a non-transmissive display device by adjusting its transmittance. The monitor 130 may include a configuration that simultaneously displays a part of an image forming the virtual space and the real space. For example, the monitor 130 may display an image of the real space captured by a camera mounted on the HMD 120, or may make the real space visually recognizable by setting a high transmittance for a part.

  In one aspect, monitor 130 may include a sub-monitor for displaying a right-eye image and a sub-monitor for displaying a left-eye image. In another aspect, the monitor 130 may be configured to display the image for the right eye and the image for the left eye integrally. In this case, the monitor 130 includes a high-speed shutter. The high-speed shutter operates so that an image for the right eye and an image for the left eye can be displayed alternately so that the image is recognized only by one of the eyes.

  In one aspect, the HMD 120 includes a plurality of light sources (not shown). Each light source is realized by, for example, an LED (Light Emitting Diode) that emits infrared light. The HMD sensor 410 has a position tracking function for detecting the movement of the HMD 120. More specifically, HMD sensor 410 reads a plurality of infrared rays emitted by HMD 120, and detects the position and inclination of HMD 120 in the real space.

  In another aspect, the HMD sensor 410 may be realized by a camera. In this case, the HMD sensor 410 can detect the position and the inclination of the HMD 120 by executing image analysis processing using the image information of the HMD 120 output from the camera.

  In another aspect, the HMD 120 may include a sensor 190 as a position detector instead of, or in addition to, the HMD sensor 410. The HMD 120 can detect the position and inclination of the HMD 120 itself using the sensor 190. For example, when the sensor 190 is an angular velocity sensor, a geomagnetic sensor, or an acceleration sensor, the HMD 120 can detect its own position and inclination by using any of these sensors instead of the HMD sensor 410. As an example, when the sensor 190 is an angular velocity sensor, the angular velocity sensor detects the angular velocity around the three axes of the HMD 120 in the real space over time. The HMD 120 calculates a temporal change of an angle around three axes of the HMD 120 based on each angular velocity, and further calculates a tilt of the HMD 120 based on a temporal change of the angle.

  The gaze sensor 140 detects a direction in which the line of sight of the right eye and the left eye of the user 5 is directed. That is, the gaze sensor 140 detects the line of sight of the user 5. The detection of the direction of the line of sight is realized by, for example, a known eye tracking function. The gaze sensor 140 is realized by a sensor having the eye tracking function. In one aspect, it is preferable that the gaze sensor 140 includes a sensor for the right eye and a sensor for the left eye. The gaze sensor 140 may be, for example, a sensor that irradiates infrared light to the right and left eyes of the user 5 and detects the rotation angle of each eyeball by receiving reflected light from the cornea and the iris with respect to the irradiated light. . The gaze sensor 140 can detect the line of sight of the user 5 based on the detected rotation angles.

  The first camera 150 photographs the lower part of the face of the user 5. More specifically, first camera 150 captures the nose and mouth of user 5 and the like. The second camera 160 captures an image of the user 5's eyes and eyebrows. The case of the user 5 of the HMD 120 is defined as the inside of the HMD 120, and the case of the HMD 120 opposite to the user 5 is defined as the outside of the HMD 120. In some aspects, the first camera 150 may be located outside the HMD 120 and the second camera 160 may be located inside the HMD 120. The images generated by the first camera 150 and the second camera 160 are input to the computer 200. In another aspect, the first camera 150 and the second camera 160 may be realized as one camera, and the face of the user 5 may be photographed by the one camera.

  The microphone 170 converts the utterance of the user 5 into an audio signal (electric signal) and outputs it to the computer 200. The speaker 180 converts the audio signal into audio and outputs the audio to the user 5. In another aspect, HMD 120 may include an earphone instead of speaker 180.

  The controller 300 is connected to the computer 200 by wire or wirelessly. Controller 300 accepts an input of a command from user 5 to computer 200. In a certain aspect, the controller 300 is configured to be graspable by the user 5. In another aspect, the controller 300 is configured to be attachable to a part of the body or clothing of the user 5. In yet another aspect, the controller 300 may be configured to output at least one of vibration, sound, and light based on a signal transmitted from the computer 200. In still another aspect, controller 300 receives an operation from user 5 for controlling the position and movement of an object placed in the virtual space.

  In one aspect, controller 300 includes a plurality of light sources. Each light source is realized by, for example, an LED that emits infrared light. The HMD sensor 410 has a position tracking function. In this case, the HMD sensor 410 reads a plurality of infrared rays emitted from the controller 300 and detects the position and the inclination of the controller 300 in the real space. In another aspect, the HMD sensor 410 may be realized by a camera. In this case, the HMD sensor 410 can detect the position and the inclination of the controller 300 by executing image analysis processing using the image information of the controller 300 output from the camera.

  In a certain situation, the motion sensor 420 is attached to the hand of the user 5 and detects a movement of the hand of the user 5. For example, the motion sensor 420 detects a rotation speed, a rotation speed, and the like of the hand. The detected signal is sent to the computer 200. The motion sensor 420 is provided in the controller 300, for example. In one aspect, the motion sensor 420 is provided in, for example, the controller 300 configured to be grippable by the user 5. In another aspect, for safety in the real space, the controller 300 is mounted on a glove-shaped object that is not easily fly by being mounted on the hand of the user 5. In yet another aspect, a sensor that is not worn by the user 5 may detect the movement of the hand of the user 5. For example, a signal from a camera that captures the user 5 may be input to the computer 200 as a signal representing the operation of the user 5. The motion sensor 420 and the computer 200 are mutually connected by wireless as an example. In the case of wireless communication, the communication mode is not particularly limited, and for example, Bluetooth (registered trademark) or another known communication method is used.

  The display 430 displays an image similar to the image displayed on the monitor 130. This allows a user other than the user 5 wearing the HMD 120 to view the same image as the user 5. The image displayed on the display 430 need not be a three-dimensional image, but may be a right-eye image or a left-eye image. Examples of the display 430 include a liquid crystal display and an organic EL monitor.

  The server 600 can transmit a program to the computer 200. In another aspect, server 600 may communicate with other computers 200 to provide virtual reality to HMD 120 used by other users. For example, when a plurality of users play a participatory game in an amusement facility, each computer 200 communicates a signal based on the operation of each user with another computer 200 via the server 600, and transmits a plurality of signals in the same virtual space. Of users can enjoy a common game. Each computer 200 may communicate a signal based on the operation of each user with another computer 200 without passing through the server 600.

  The external device 700 may be any device as long as it can communicate with the computer 200. The external device 700 may be, for example, a device capable of communicating with the computer 200 via the network 2 or a device capable of directly communicating with the computer 200 through short-range wireless communication or wired connection. Examples of the external device 700 include a smart device, a PC (Personal Computer), and peripheral devices of the computer 200, but are not limited thereto.

[Computer hardware configuration]
With reference to FIG. 2, a computer 200 according to the present embodiment will be described. FIG. 2 is a block diagram illustrating an example of a hardware configuration of computer 200 according to the present embodiment. The computer 200 includes a processor 210, a memory 220, a storage 230, an input / output interface 240, and a communication interface 250 as main components. Each component is connected to the bus 260.

  The processor 210 executes a series of instructions included in a program stored in the memory 220 or the storage 230 based on a signal provided to the computer 200 or based on satisfaction of a predetermined condition. In one aspect, the processor 210 is realized as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an MPU (Micro Processor Unit), an FPGA (Field-Programmable Gate Array), or another device.

  The memory 220 temporarily stores programs and data. The program is loaded from the storage 230, for example. The data includes data input to computer 200 and data generated by processor 210. In one aspect, the memory 220 is realized as a random access memory (RAM) or other volatile memory.

  The storage 230 permanently stores programs and data. The storage 230 is realized, for example, as a ROM (Read-Only Memory), a hard disk device, a flash memory, or another nonvolatile storage device. The programs stored in the storage 230 include a program for providing a virtual space in the HMD system 100, a simulation program, a game program, a user authentication program, and a program for realizing communication with another computer 200. The data stored in the storage 230 includes data for defining a virtual space, objects, and the like.

  In another aspect, the storage 230 may be realized as a removable storage device such as a memory card. In still another aspect, a configuration using programs and data stored in an external storage device may be used instead of the storage 230 built in the computer 200. According to such a configuration, for example, in a situation where a plurality of HMD systems 100 are used as in an amusement facility, it is possible to update programs and data collectively.

  The input / output interface 240 communicates signals with the HMD 120, the HMD sensor 410, the motion sensor 420, and the display 430. The monitor 130, the gaze sensor 140, the first camera 150, the second camera 160, the microphone 170, and the speaker 180 included in the HMD 120 can communicate with the computer 200 via the input / output interface 240 of the HMD 120. In one aspect, the input / output interface 240 is implemented using a USB (Universal Serial Bus), DVI (Digital Visual Interface), HDMI (registered trademark) (High-Definition Multimedia Interface), or other terminal. The input / output interface 240 is not limited to the above.

  In certain aspects, input / output interface 240 may further communicate with controller 300. For example, the input / output interface 240 receives signals output from the controller 300 and the motion sensor 420. In another aspect, the input / output interface 240 sends the instruction output from the processor 210 to the controller 300. The command instructs the controller 300 to perform vibration, sound output, light emission, and the like. Upon receiving the command, the controller 300 executes any of vibration, sound output, and light emission according to the command.

  The communication interface 250 is connected to the network 2 and communicates with another computer (for example, the server 600) connected to the network 2. In one aspect, the communication interface 250 is implemented as, for example, a LAN (Local Area Network) or other wired communication interface, or a wireless communication interface such as WiFi (Wireless Fidelity), Bluetooth (registered trademark), NFC (Near Field Communication), or the like. Is done. The communication interface 250 is not limited to the above.

  In one aspect, the processor 210 accesses the storage 230, loads one or more programs stored in the storage 230 into the memory 220, and executes a series of instructions included in the program. The one or more programs may include an operating system of the computer 200, an application program for providing a virtual space, game software executable in the virtual space, and the like. The processor 210 sends a signal for providing a virtual space to the HMD 120 via the input / output interface 240. HMD 120 displays an image on monitor 130 based on the signal.

  In the example illustrated in FIG. 2, the configuration in which the computer 200 is provided outside the HMD 120 is illustrated. However, in another aspect, the computer 200 may be built in the HMD 120. As an example, a portable information communication terminal (for example, a smartphone) including the monitor 130 may function as the computer 200.

  The computer 200 may have a configuration commonly used by a plurality of HMDs 120. According to such a configuration, for example, the same virtual space can be provided to a plurality of users, so that each user can enjoy the same application as another user in the same virtual space.

  In one embodiment, in the HMD system 100, a real coordinate system that is a coordinate system in the real space is set in advance. The real coordinate system has three reference directions (axes) parallel to the vertical direction in the real space, a horizontal direction orthogonal to the vertical direction, and a front-rear direction orthogonal to both the vertical direction and the horizontal direction. The horizontal direction, vertical direction (vertical direction), and front-back direction in the real coordinate system are defined as x-axis, y-axis, and z-axis, respectively. More specifically, in the real coordinate system, the x-axis is parallel to the horizontal direction of the real space. The y-axis is parallel to the vertical direction of the real space. The z-axis is parallel to the front-back direction of the real space.

  In one aspect, the HMD sensor 410 includes an infrared sensor. When the infrared sensor detects infrared rays emitted from each light source of the HMD 120, the presence of the HMD 120 is detected. The HMD sensor 410 further detects the position and the inclination (direction) of the HMD 120 in the real space according to the movement of the user 5 wearing the HMD 120, based on the value of each point (each coordinate value in the real coordinate system). I do. More specifically, the HMD sensor 410 can detect a temporal change in the position and the inclination of the HMD 120 using each value detected over time.

  Each inclination of the HMD 120 detected by the HMD sensor 410 corresponds to each inclination around three axes of the HMD 120 in the real coordinate system. The HMD sensor 410 sets the uvw visual field coordinate system to the HMD 120 based on the inclination of the HMD 120 in the real coordinate system. The uvw visual field coordinate system set in the HMD 120 corresponds to a viewpoint coordinate system when the user 5 wearing the HMD 120 views an object in a virtual space.

[Uvw visual field coordinate system]
The uvw visual field coordinate system will be described with reference to FIG. FIG. 3 is a diagram conceptually showing a uvw visual field coordinate system set in HMD 120 according to an embodiment. The HMD sensor 410 detects the position and the inclination of the HMD 120 in the real coordinate system when the HMD 120 starts. The processor 210 sets the uvw visual field coordinate system to the HMD 120 based on the detected value.

  As illustrated in FIG. 3, the HMD 120 sets a three-dimensional uvw visual field coordinate system centered on the head (origin) of the user 5 wearing the HMD 120. More specifically, the HMD 120 adjusts the horizontal direction, the vertical direction, and the front-rear direction (x-axis, y-axis, z-axis) that define the real coordinate system by tilts around the respective axes of the HMD 120 in the real coordinate system. Three directions newly obtained by tilting around the axes are set as a pitch axis (u axis), a yaw axis (v axis), and a roll axis (w axis) of the uvw visual field coordinate system in the HMD 120.

  In a certain situation, when the user 5 wearing the HMD 120 is standing upright and viewing the front, the processor 210 sets the uvw view coordinate system parallel to the real coordinate system to the HMD 120. In this case, the horizontal direction (x-axis), the vertical direction (y-axis), and the front-rear direction (z-axis) in the real coordinate system are the pitch axis (u-axis) and the yaw axis (v-axis) of the uvw visual field coordinate system in the HMD 120. , And the roll axis (w-axis).

  After the uvw view coordinate system is set to the HMD 120, the HMD sensor 410 can detect the inclination of the HMD 120 in the set uvw view coordinate system based on the movement of the HMD 120. In this case, the HMD sensor 410 detects the pitch angle (θu), the yaw angle (θv), and the roll angle (θw) of the HMD 120 in the uvw visual field coordinate system, respectively, as the inclination of the HMD 120. The pitch angle (θu) represents the inclination angle of the HMD 120 around the pitch axis in the uvw visual field coordinate system. The yaw angle (θv) represents the inclination angle of the HMD 120 around the yaw axis in the uvw visual field coordinate system. The roll angle (θw) indicates the inclination angle of the HMD 120 about the roll axis in the uvw visual field coordinate system.

  The HMD sensor 410 sets the uvw view coordinate system of the HMD 120 after the HMD 120 has moved to the HMD 120 based on the detected inclination of the HMD 120. The relationship between the HMD 120 and the uvw visual field coordinate system of the HMD 120 is always constant regardless of the position and inclination of the HMD 120. When the position and the inclination of the HMD 120 change, the position and the inclination of the uvw visual field coordinate system of the HMD 120 in the real coordinate system change in conjunction with the change in the position and the inclination.

  In one aspect, the HMD sensor 410 determines the HMD 120 based on the light intensity of the infrared light acquired based on the output from the infrared sensor and the relative positional relationship between a plurality of points (for example, the distance between the points). May be specified as a relative position with respect to the HMD sensor 410. The processor 210 may determine the origin of the uvw view coordinate system of the HMD 120 in the real space (real coordinate system) based on the specified relative position.

[Virtual space]
The virtual space will be further described with reference to FIG. FIG. 4 is a diagram conceptually showing one mode of expressing virtual space 11 according to an embodiment. The virtual space 11 has a spherical structure that covers the entire center 12 in the 360-degree direction. FIG. 4 illustrates the upper half celestial sphere of the virtual space 11 in order not to complicate the description. In the virtual space 11, each mesh is defined. The position of each mesh is defined in advance as a coordinate value in an XYZ coordinate system which is a global coordinate system defined in the virtual space 11. The computer 200 associates each partial image forming the panoramic image 13 (still image, moving image, or the like) that can be developed in the virtual space 11 with each corresponding mesh in the virtual space 11.

  In a certain situation, in the virtual space 11, an XYZ coordinate system having the center 12 as the origin is defined. The XYZ coordinate system is, for example, parallel to the real coordinate system. The horizontal direction, the vertical direction (vertical direction), and the front-back direction in the XYZ coordinate system are defined as an X axis, a Y axis, and a Z axis, respectively. Therefore, the X axis (horizontal direction) of the XYZ coordinate system is parallel to the x axis of the real coordinate system, the Y axis (vertical direction) of the XYZ coordinate system is parallel to the y axis of the real coordinate system, and The Z axis (front-back direction) is parallel to the z axis of the real coordinate system.

  When the HMD 120 is activated, that is, in the initial state of the HMD 120, the virtual camera 14 is arranged at the center 12 of the virtual space 11. In one aspect, the processor 210 displays an image captured by the virtual camera 14 on the monitor 130 of the HMD 120. The virtual camera 14 similarly moves in the virtual space 11 in conjunction with the movement of the HMD 120 in the real space. Thereby, the change of the position and the inclination of the HMD 120 in the real space can be similarly reproduced in the virtual space 11.

  The uvw visual field coordinate system is defined for the virtual camera 14 as in the case of the HMD 120. The uvw view coordinate system of the virtual camera 14 in the virtual space 11 is defined so as to be linked to the uvw view coordinate system of the HMD 120 in the real space (real coordinate system). Therefore, when the inclination of the HMD 120 changes, the inclination of the virtual camera 14 changes accordingly. The virtual camera 14 can also move in the virtual space 11 in conjunction with the movement of the user 5 wearing the HMD 120 in the real space.

  The processor 210 of the computer 200 defines the view area 15 in the virtual space 11 based on the position and the inclination (reference line of sight 16) of the virtual camera 14. The view area 15 corresponds to an area in the virtual space 11 that is visually recognized by the user 5 wearing the HMD 120. That is, the position of the virtual camera 14 can be said to be the viewpoint of the user 5 in the virtual space 11.

  The line of sight of the user 5 detected by the gaze sensor 140 is the direction in the viewpoint coordinate system when the user 5 visually recognizes the object. The uvw view coordinate system of the HMD 120 is equal to the viewpoint coordinate system when the user 5 views the monitor 130. The uvw view coordinate system of the virtual camera 14 is linked to the uvw view coordinate system of the HMD 120. Therefore, the HMD system 100 according to a certain aspect can regard the line of sight of the user 5 detected by the gaze sensor 140 as the line of sight of the user 5 in the uvw visual field coordinate system of the virtual camera 14.

[User's eyes]
The determination of the line of sight of the user 5 will be described with reference to FIG. FIG. 5 is a diagram showing the head of user 5 wearing HMD 120 according to an embodiment from above.

  In a certain situation, the gaze sensor 140 detects each line of sight of the right eye and the left eye of the user 5. In a certain situation, when the user 5 is looking near, the gaze sensor 140 detects the lines of sight R1 and L1. In another aspect, when the user 5 is looking far away, the gaze sensor 140 detects the lines of sight R2 and L2. In this case, the angle formed by the lines of sight R2 and L2 with respect to the roll axis w is smaller than the angle formed by the lines of sight R1 and L1 with respect to the roll axis w. The gaze sensor 140 transmits the detection result to the computer 200.

  When the computer 200 receives the detection values of the lines of sight R1 and L1 from the gaze sensor 140 as the detection result of the line of sight, the computer 200 specifies the gazing point N1 which is the intersection of the lines of sight R1 and L1 based on the detection values. On the other hand, when the computer 200 receives the detection values of the sight lines R2 and L2 from the gaze sensor 140, the computer 200 specifies the intersection of the sight lines R2 and L2 as the gazing point. The computer 200 specifies the line of sight N0 of the user 5 based on the specified position of the gazing point N1. The computer 200 detects, as the line of sight N0, for example, the direction in which the straight line passing through the midpoint of the straight line connecting the right eye R and the left eye L of the user 5 and the gazing point N1. The line of sight N0 is a direction in which the user 5 is actually turning his or her line of sight with both eyes. The line of sight N0 corresponds to the direction in which the user 5 is actually pointing the line of sight to the field of view 15.

  In another aspect, the HMD system 100 may include a television broadcast receiving tuner. According to such a configuration, the HMD system 100 can display a television program in the virtual space 11.

  In still another aspect, the HMD system 100 may include a communication circuit for connecting to the Internet or a call function for connecting to a telephone line.

[Visibility area]
The visibility area 15 will be described with reference to FIGS. FIG. 6 is a diagram illustrating a YZ cross section of the visual field 15 viewed in the X direction in the virtual space 11. FIG. 7 is a diagram illustrating an XZ cross section of the visual field 15 in the virtual space 11 viewed from the Y direction.

  As shown in FIG. 6, the visibility region 15 in the YZ section includes a region 18. The area 18 is defined by the position of the virtual camera 14, the reference line of sight 16, and the YZ section of the virtual space 11. The processor 210 defines a range including the polar angle α around the reference line of sight 16 in the virtual space as the region 18.

  As shown in FIG. 7, the visibility region 15 in the XZ section includes a region 19. The area 19 is defined by the position of the virtual camera 14, the reference line of sight 16, and the XZ cross section of the virtual space 11. The processor 210 defines a range including the azimuth β around the reference line of sight 16 in the virtual space 11 as the region 19. The polar angles α and β are determined according to the position of the virtual camera 14 and the inclination (direction) of the virtual camera 14.

  In one aspect, the HMD system 100 provides the user 5 with a view in the virtual space 11 by displaying the view image 17 on the monitor 130 based on a signal from the computer 200. The view image 17 is an image corresponding to a portion corresponding to the view area 15 in the panoramic image 13. When the user 5 moves the HMD 120 mounted on the head, the virtual camera 14 also moves in conjunction with the movement. As a result, the position of the view area 15 in the virtual space 11 changes. As a result, the view image 17 displayed on the monitor 130 is updated to an image of the panoramic image 13 that is superimposed on the view area 15 in the direction in which the user 5 is facing in the virtual space 11. The user 5 can visually recognize a desired direction in the virtual space 11.

  As described above, the inclination of the virtual camera 14 corresponds to the line of sight of the user 5 in the virtual space 11 (the reference line of sight 16), and the position where the virtual camera 14 is arranged corresponds to the viewpoint of the user 5 in the virtual space 11. Therefore, by changing the position or the inclination of the virtual camera 14, the image displayed on the monitor 130 is updated, and the field of view of the user 5 is moved.

  While wearing the HMD 120, the user 5 can visually recognize only the panoramic image 13 developed in the virtual space 11 without visually recognizing the real world. Therefore, the HMD system 100 can provide the user 5 with a high sense of immersion in the virtual space 11.

  In one aspect, the processor 210 may move the virtual camera 14 in the virtual space 11 in conjunction with the movement of the user 5 wearing the HMD 120 in the real space. In this case, the processor 210 specifies an image area (view area 15) projected on the monitor 130 of the HMD 120 based on the position and the inclination of the virtual camera 14 in the virtual space 11.

  In one aspect, virtual camera 14 may include two virtual cameras, a virtual camera for providing an image for the right eye and a virtual camera for providing an image for the left eye. Appropriate parallax is set for the two virtual cameras so that the user 5 can recognize the three-dimensional virtual space 11. In another aspect, the virtual camera 14 may be realized by one virtual camera. In this case, a right-eye image and a left-eye image may be generated from an image obtained by one virtual camera. In the present embodiment, the virtual camera 14 includes two virtual cameras, and the roll axis (w) generated by combining the roll axes of the two virtual cameras is adapted to the roll axis (w) of the HMD 120. The technical idea according to the present disclosure will be exemplified as having such a configuration.

  The operation of the user 5B (the operation of the HMD 120B and the operation of the controller 300B) is reflected on the avatar object 6B arranged in the virtual space 11A by the processor 210A. Thereby, the user 5A can recognize the action of the user 5B through the avatar object 6B.

  FIG. 13 is a sequence chart showing a part of processing executed in HMD system 100 according to the present embodiment. Although the HMD set 110D is not shown in FIG. 13, the HMD set 110D operates similarly to the HMD sets 110A, 110B, and 110C. Also in the following description, A is attached to the reference numeral of each component related to the HMD set 110A, B is attached to the reference numeral of each component related to the HMD set 110B, and C is added to the reference numeral of each component related to the HMD set 110C. It is assumed that D is added to the reference numeral of each component related to the HMD set 110D.

  In step S1310A, the processor 210A in the HMD set 110A acquires avatar information for determining the operation of the avatar object 6A in the virtual space 11A. The avatar information includes, for example, information about the avatar such as motion information, face tracking data, and audio data. The motion information includes information indicating a temporal change in the position and inclination of the HMD 120A, information indicating a hand motion of the user 5A detected by the motion sensor 420A and the like. The face tracking data includes data for specifying the position and size of each part of the face of the user 5A. The face tracking data includes data indicating the movement of each organ constituting the face of the user 5A and line-of-sight data. The audio data includes data indicating the audio of the user 5A acquired by the microphone 170A of the HMD 120A. The avatar information may include information specifying the avatar object 6A or the user 5A associated with the avatar object 6A, information specifying the virtual space 11A where the avatar object 6A exists, and the like. The information for specifying the avatar object 6A and the user 5A includes a user ID. Room ID is given as information for specifying the virtual space 11A in which the avatar object 6A exists. The processor 210A transmits the avatar information acquired as described above to the server 600 via the network 2.

  In step S1310B, the processor 210B in the HMD set 110B acquires avatar information for determining the operation of the avatar object 6B in the virtual space 11B, and transmits the avatar information to the server 600, as in the process in step S1310A. Similarly, in step S1310C, the processor 210C in the HMD set 110C acquires avatar information for determining the operation of the avatar object 6C in the virtual space 11C, and transmits the avatar information to the server 600.

  In step S1320, server 600 temporarily stores player information received from each of HMD set 110A, HMD set 110B, and HMD set 110C. The server 600 integrates the avatar information of all the users (in this example, the users 5A to 5C) associated with the common virtual space 11, based on the user ID and the room ID included in each avatar information. Then, the server 600 transmits the integrated avatar information to all users associated with the virtual space 11 at a predetermined timing. As a result, a synchronization process is performed. By such a synchronization process, the HMD set 110A, the HMD set 110B, and the HMD 110C can share their avatar information at substantially the same timing.

  Subsequently, based on the avatar information transmitted from the server 600 to each of the HMD sets 110A to 110C, each of the HMD sets 110A to 110C executes the processing of steps S1330A to S1330C. The process in step S1330A corresponds to the process in step S1180 in FIG.

  In step S1330A, the processor 210A in the HMD set 110A updates information on the avatar objects 6B and 6C of the other users 5B and 5C in the virtual space 11A. Specifically, the processor 210A updates the position, the orientation, and the like of the avatar object 6B in the virtual space 11 based on the motion information included in the avatar information transmitted from the HMD set 110B. For example, the processor 210A updates information (position, orientation, etc.) of the avatar object 6B included in the object information stored in the memory module 530. Similarly, the processor 210A updates information (position, orientation, and the like) of the avatar object 6C in the virtual space 11 based on the motion information included in the avatar information transmitted from the HMD set 110C.

  In step S1330B, the processor 210B in the HMD set 110B updates the information on the avatar objects 6A, 6C of the users 5A, 5C in the virtual space 11B, similarly to the processing in step S1330A. Similarly, in step S1330C, the processor 210C in the HMD set 110C updates information on the avatar objects 6A, 6B of the users 5A, 5B in the virtual space 11C.

[Detailed configuration of module]
The details of the module configuration of the computer 200 will be described with reference to FIG. FIG. 14 is a block diagram showing a detailed configuration of a module of computer 200 according to an embodiment.

The rendering module 520 includes a view image generation module 1438. The memory module 530 holds space information 1431, object information 1432, and user information 1433.

  The virtual camera control module 1421 arranges the virtual camera 14 (virtual viewpoint) in the virtual space 11. The virtual camera control module 1421 controls the arrangement position of the virtual camera 14 in the virtual space 11 and the direction (tilt) of the virtual camera 14. The view area determination module 1422 defines the view area 15 (view) according to the orientation of the head of the user wearing the HMD 120 and the arrangement position of the virtual camera 14. The view image generation module 1438 generates the view image 17 displayed on the monitor 130 based on the determined view area 15 and virtual space data described below.

  The reference line of sight specification module 1423 specifies the line of sight of the user 5 based on the signal from the gaze sensor 140. The motion detection module 1424 detects an organ (for example, a mouth, an eye, and an eyebrow) constituting the face of the user 5 from the image of the face of the user 5 generated by the first camera 150 and the second camera 160, and The movement (shape) of the organ is detected.

  The virtual space definition module 1425 defines the virtual space 11 in the HMD system 100 by generating virtual space data representing the virtual space 11.

  The virtual object generation module 1426 generates one or a plurality of virtual objects arranged in the virtual space 11. The virtual object can include, for example, but not limited to, a member, a structure, and a person, and can include a landscape, an animal, and the like, including a forest, a mountain, and the like arranged according to the progress of the game story. The virtual object includes an avatar object to be described later.

  The shielding target specifying module 1427 specifies a target to be shielded by a shielding object described later. The shielding target may be at least a part (shielding target part) of the virtual object such as the above person or the entire virtual object. Further, the shielding target may be an object reflected on a 360-degree video. The objects displayed on the 360-degree image may include, for example, members, structures, and people, but are not limited to these, and may include landscapes, including forests, mountains, and other animals, and animals. The shielding target specifying module 1427 may specify the shielding target part of the virtual object when the virtual object generating module 1426 generates the virtual object or after generating the virtual object.

  The virtual object control module 1428 arranges a shielding target and a shielding object (first object) for shielding the shielding target in the virtual space 11. The virtual object control module 1428 controls the arrangement (for example, including at least one of the position and the inclination) of the first object such that the obstruction target is obstructed by the first object when the obstruction is included in the view. . Here, the shielding object (first object) is an object that can shield the shielding target. For example, a so-called mosaic image or an image colored black or the like so that the shielding target can be shielded is displayed. Including. Further, the shielding object may be an object simulating a member having a planar or three-dimensional shape, and the member may include frosted glass or another translucent member having a high refractive index.

  The virtual object control module 1428 generates data for arranging an avatar object of a user of another computer 200 connected via the network 2 in the virtual space 11. In one aspect, the virtual object control module 1428 generates data for arranging the avatar object of the user 5 in the virtual space 11. In an aspect, the virtual object control module 1428 generates an avatar object imitating the user 5 based on an image including the user 5. In another aspect, the virtual object control module 1428 converts the avatar object, which has been selected by the user 5 from a plurality of types of avatar objects (for example, an object imitating an animal or an object of a deformed person), into the virtual space 11. Generate data to be placed in

  The virtual object control module 1428 reflects the movement of the HMD 120 detected by the HMD sensor 410 on the avatar object. For example, the virtual object control module 1428 detects that the HMD 120 is tilted, and generates data for tilting and arranging the avatar object. In an aspect, the virtual object control module 1428 reflects the movement of the controller 300 on the avatar object. In this case, the controller 300 includes a motion sensor, an acceleration sensor, or a plurality of light emitting elements (for example, infrared LEDs) for detecting the movement of the controller 300. The virtual object control module 1428 reflects the motion of the face organ detected by the motion detection module 1424 on the face of the avatar object arranged in the virtual space 11. That is, the virtual object control module 1428 reflects the movement of the face of the user 5A on the avatar object.

  The operation object control module 1429 arranges an operation object for accepting a user operation in the virtual space 11 in the virtual space 11. By operating the operation object, the user can move, for example, a shielding target arranged in the virtual space 11. The operation object control module 1429 associates the operation object with a shielded object (second object) having a shield target portion, which is arranged in the virtual space 11. The virtual object control module 1428 controls the arrangement of the shielded object associated with the operation object according to the movement of the operation object by the operation object control module 1429. The virtual object control module 1428 changes the arrangement of the shielding object so that the shielding target part is shielded by the shielding object (first object) in response to the change in the arrangement of the shielding target part due to the movement of the shielded object. It may be controlled.

  In one aspect, the operation object may include, for example, a hand object corresponding to the hand of the user wearing the HMD 120 or the like. In one aspect, the operation object may correspond to the hand of the avatar object described above. For example, the operation object control module 1429 moves a hand object corresponding to the hand of the user wearing the HMD 120 according to the movement of the controller 300 shown in FIG. A collision area is set in the virtual space for each of the hand object and the occluded object, and when the collision areas of both of them touch, it is determined that the hand object and the occluded object have come into contact. Further, when the bending of the finger of the user's hand is detected by pressing various buttons 340, 350, 370, 380, etc. of the controller 300 shown in FIG. 8, the finger of the hand object also bends. For example, when the hand object is in contact with the occluded object, the occluded object can be grasped by the hand object by bending the finger of the user's hand. Then, when the placement of the hand object is controlled in a state where the covered object is grasped by the hand object, the placement of the covered object also changes so as to correspond to the change in the placement of the hand object. Thus, the user can operate the controller 300 to grip or move the covered object with the hand object in the virtual space.

  When each of the objects arranged in the virtual space 11 collides with another object, the control module 510 detects the collision. The control module 510 can detect, for example, the timing at which a certain object and another object touch each other, and when the detection is performed, perform a predetermined process. The control module 510 can detect a timing at which the object leaves the state where the object is in contact with the object, and when the detection is performed, performs a predetermined process. The control module 510 can detect that the objects are touching each other. Specifically, the operation object control module 1428 detects a touch between the operation object and another object when the operation object touches another object, and performs a predetermined process. .

  The memory module 530 holds data used by the computer 200 to provide the virtual space 11 to the user 5. In one aspect, the memory module 530 holds space information 1431, object information 1432, and user information 1433.

  The space information 1431 holds one or more templates defined for providing the virtual space 11.

  The object information 1432 holds content to be reproduced in the virtual space 11, objects used in the content, and information (for example, position information) for arranging the object in the virtual space 11. The content may include, for example, a game, a content representing a landscape similar to the real world, or the like.

  The user information 1433 holds a program for causing the computer 200 to function as a control device of the HMD system 100, an application program using each content held in the object information 1432, and the like.

[Control structure of HMD system]
The control structure of the HMD set 110 will be described with reference to FIG. FIG. 15 is a sequence chart showing a part of processing executed in HMD set 110 according to an embodiment. Steps S1110 to S1140 and S1160 to S1190 in FIG. 15 are the same as steps S1110 to S1140 and S1160 to S1190 in FIG.

  In step S1550, processor 210 executes the application program and specifies a shielding target from one or a plurality of virtual objects arranged in virtual space 11, based on an instruction included in the application program. In addition, the processor 210 may specify at least a part of the shielded object as a shielding target part.

  In step S1560, processor 210 executes the application program and controls the placement of the shielding object in virtual space 11 so that the shielding target is shielded by the shielding object based on the instructions included in the application program.

  FIG. 16 is a diagram for explaining control for shielding the shielded object 8A (shielding target) by the shielding object 8C. FIG. 16A is a diagram illustrating the view area 15 viewed from the Y direction in the virtual space including the occluded object 8A, and a view image 17B viewed from the virtual camera 14. FIG. 16B is a diagram showing a view area 15 viewed from the Y direction in the virtual space including the covered object 8A and the cover object 8C, and a view image 17B viewed from the virtual camera 14. In the example of FIG. 16B, compared to the example of FIG. 16A, the virtual camera 14 and the virtual camera 14 are blocked in the Z-axis direction so that the blocked object 8A is blocked by the blocked object 8C when viewed from the virtual camera 14. A shielding object 8C is newly arranged between the shielding object 8A and the shielding object 8A. The shielding object 8C has a shape having a plane S. The placement of the occluded object is performed according to the control of the virtual object control module 1428 shown in FIG.

  The virtual object control module 1428 also controls the direction of the shielding object (first object), and controls, for example, the plane S of the shielding object 8C to be perpendicular to the Z-axis direction of the virtual camera 14. In this case, a wider area can be shielded than when the plane S is not perpendicular to the Z-axis direction of the virtual camera 14.

  FIG. 17 is a diagram for explaining control for always shielding the shielded object 8A when the shielded object 8C (movement target) moves following the movement of the shielded object 8A. FIG. 17A is a diagram of the virtual space including the shielded object 8A and the shielded object 8C as viewed from the Y direction, and a view image viewed from the virtual camera 14 in which the shielded object 8A is shielded by the shielded object 8C. FIG.

  FIG. 17B shows a state after the shielded object 8A has moved from the example shown in FIG. 17A. In the virtual space including the shielded object 8A and the shielded object 8C, the view area is set in the Y direction. FIG. 3 is a diagram showing a view seen from a virtual camera 14 and a view image seen from a virtual camera 14. The shielded object 8A has moved from the position in FIG. 17A to the position in FIG. 17B. Following this movement, the shielded object 8C also moves under the control of the virtual object control module 1428 so that the shielded object 8A is shielded by the shielded object 8C. At this time, the shielding object 8C may be moved while always maintaining the positional relationship where the plane S of the shielding object 8C is perpendicular to the Z-axis direction of the virtual camera 14. In this example, the example in which the shielded object 8C follows the moved shielded object 8A has been described. However, the shielded object 8A does not move but the virtual camera 14 moves and the shielded object 8C moves out of the shielded area. When the shielding object 8A is likely to come off, the shielding object 8C may be moved to maintain the shielding state.

  Various methods can be employed for controlling the arrangement of the shielding object 8C. For example, virtual object control module 1428 may employ billboard control. The virtual object control module 1428 controls the shielding object 8C such that, for example, the plane of the shielding object 8C having a plane is always perpendicular to the line of sight of the virtual camera 14. That is, the virtual object control module 1428 controls the shielded object 8C such that the plane of the shielded object 8C having the plane always faces the front when viewed from the user 5 shown in FIG.

  According to this configuration, even when the arrangement of at least one of the virtual camera 14 and the shielded object 8A is changed, the shielded object 8A is appropriately shielded by the shielded object 8C.

FIG. 18A is a diagram of a view area viewed from the Y direction in a virtual space including a shielded object and a shielded object. FIG. 18B shows a state in which the distance between the virtual camera and the occluded object is larger than that in the example of FIG. As shown in each figure, the virtual object control module 1428 shown in FIG. 14 determines that the distance in the Z direction (depth direction) of the shielded object (first object) from the shielded object 8A (shielding target) is The arrangement of the shielding object is controlled so as to be a distance corresponding to the distance in the Z direction from the shielding object 8A. For example, when the distance between the virtual camera 14 and the occluded object 8A increases (when L3 in FIG. 18A increases to L4 in FIG. 18B), the virtual object control module 1428 The distance between the object 8A and the shielding object 8C is controlled from L1 to L2 longer than L1. More specifically, when calculating the distance L2, the virtual object control module 1428 refers to the following expression indicating the ratio of the distance between the virtual camera 14 and the shielded object 8A. Note that the method of calculating the distance L2 of the virtual object control module 1428 is not limited to the method referring to the following equation.
[formula]
L2 = (distance L4 between virtual camera 14 and occluded object 8A / distance L3 between virtual camera 14 and occluded object 8A) × L1

  According to this configuration, the distance between the covered object 8A and the covered object 8C is dynamically controlled according to the distance between the virtual camera 14 and the covered object 8A. Irrespective of a change in the distance from the object 8A, the shielded object 8A is appropriately shielded by the shield object 8C.

  The virtual object control module 1428 controls the distance between the shielded object 8A and the shielded object 8C according to the distance between the virtual camera 14 and the shielded object 8A. May be controlled. The virtual object control module 1428 controls the distance between the shielded object 8A and the shielded object 8C in accordance with the distance between the virtual camera 14 and the shielded object 8A. May be controlled. The virtual object control module 1428 may not only control the position of the shielding object 8C but also further control the inclination of the shielding object 8C.

  According to this configuration, since the shape of the occluded object 8C is controlled according to the distance between the virtual camera 14 and the occluded object 8A, the shape of the occluded object 8C is controlled by the change in the distance between the virtual camera 14 and the occluded object 8A. Instead, the shielded object 8A is appropriately shielded by the shield object 8C.

  FIG. 19 is a diagram illustrating a view image 17D in which the face (shielding target portion) of the shielded object 8A is shielded by the shield object 8C. As shown in FIG. 19, as the shielding object 8C, in order to shield the face of the shielded object 8A, a circular member in which “?” Is arranged at the center of the circle may be employed. The shielding object 8C is not limited to this, and may be a virtual object imitating a member having a planar or three-dimensional shape. The member may include frosted glass or another translucent member having a high refractive index, which can shield at least a part of the shielded object 8A. In addition, the shielding object 8C may include a mosaic image showing a picture or an icon image in which small pieces are brought together, or an image colored black or the like so that at least a part of the shielded object 8A can be shielded.

  As described above, according to the present embodiment, in the view image, control is performed so that the shielding object is arranged between the virtual camera and the shielding object so that the shielding target portion of the shielding object is shielded by the shielding object. . Therefore, for example, depending on attributes such as the age of the player, it is possible to sufficiently respond to a request that it is necessary to conceal a specific part of the virtual object displayed in the VR space configuring the game. Thus, according to the present embodiment, the virtual experience of the user can be improved.

  Each of the above embodiments is intended to facilitate understanding of the present invention, and is not to be construed as limiting the present invention. The present invention can be modified / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  In the virtual object control module 1428 illustrated in FIG. 14, for example, the avatar object 6B associated with the user 5B wearing the HMD 120B illustrated in FIG. 12 may be a shielded object. In this case, the virtual object control module 1428 obtains motion data for operating the avatar object 6B from the computer 200B, and operates the avatar object 6B according to the obtained motion data. Then, the virtual object control module 1428 responds to the movement of the avatar object 6B by changing the arrangement of the shielding target portion that is at least a part of the avatar object 6B, so that the shielding target portion is shielded by the shielding object. The arrangement of the shielding object may be controlled. Here, the case where the occluded object is the avatar object 6B that operates in conjunction with the movement of the user B has been described. However, the present invention is not limited to this, and the occluded object is an avatar object controlled by NPC (Non Player Character). There may be.

  The virtual object control module 1428 may control the display mode of the occluded object at an arbitrary timing. In addition, the virtual object control module 1428 displays the shielded object (first object) before the predetermined condition is satisfied in the first mode, and displays the shielded object after the predetermined condition is satisfied more than the first mode. Are displayed in the second mode where the degree of shielding is low. Here, the mode in which the degree of shielding is low includes an aspect in which the shielding range is narrow, an aspect in which the transmittance of the shielding portion is high, and the like. The predetermined condition includes, for example, a condition relating to at least one of progress of a game formed by the virtual space, charging in the game, and use of an item in the game. Specifically, when the predetermined condition is satisfied, an event in the game is cleared, a charge (for example, cash or electronic money is paid or a money-sending action is performed) is executed in the game, or And consumption of items in the game (including billing items obtained by paying cash, electronic money, and the like).

  This embodiment is also applicable to the following games. For example, in the sample version or beta version, a predetermined shielding target site is shielded, but when the official version is obtained, the game is a game in which the shielding of the relevant site is released or a game in which the object covered by mosaic is applied. A game in which mosaics are released in stages according to the progress of other games or events, or a game in which mosaics are released as a reward for clearing a game or event Is mentioned.

  Note that the above-described view image is a 360-degree moving image, and the virtual object included in the view image may correspond to a person or the like included in the 360-degree moving image. For example, the computer 200 performs image recognition processing on a 360-degree moving image, and includes the image data in a 360-degree moving image based on predetermined setting information, for example, setting information indicating that a person's head is shielded in advance. At least a part of the shielding target site such as a person to be shielded may be specified. Further, the 360-degree moving image may be photographed with a marker or the like attached to a position to be shielded in advance, based on predetermined setting information, and may be acquired and recorded as image data by photographing.

  On the other hand, the computer 200 may specify at least a part of the shielding target part such as a person included in the 360-degree moving image based on an instruction from the user. For example, the user may confirm at least a part of a shielding target portion such as a person included in the 360-degree moving image while confirming the 360-degree moving image on a monitor or another display device, and may instruct the computer 200. Note that the user may notify the computer of the shielding target portion by designating the shielding target portion on the display device. In addition, the computer 200 may specify the shielding target part by detecting the user's line of sight using a line of sight sensor such as a gaze sensor mounted on the HMD.

  FIG. 20 shows a view image (first view image) in which the shielding target part of the shielded object is not shielded by the shielding object in the HMD set, and the shielding target part of the shielded object in the other HMD sets. FIG. 8 is a diagram illustrating an example in which a view image (a second view image) is displayed, which is blocked by a cover object. The HMD set 110A associated with the user 5 shown in FIG. 1 generates a view image in which a shield object 8C is arranged between a virtual camera (not shown) and the shielded object 8A, and generates a view object 8C in the view image. Is specified. The position information PI is information indicating the position of the shielding object 8C, and in the example of FIG. 20, the outer periphery of the shielding object 8C is shown. However, the present invention is not limited to this, and coordinate information such as the center point of the shielding object 8C is used. It may be.

  Then, as shown in FIG. 20, the HMD set 110A displays, for example, a view image 17E in which the display form of the shielding object 8C is in a transparent state, that is, the shielding object 8C is not displayed on the HMD 120A. In addition, regarding the display form of the shielded object 8C, it is sufficient that the shielded object 8A can be visually recognized. Therefore, not only the display form of the shielded object 8C is made transparent, but also the display form of the shielded object 8C is made translucent. A display mode can be adopted.

  In addition, the HMD set 110A transmits, to an HMD set associated with another user, a view image in which the shielding object 8C is arranged between the virtual camera and the shielded object 8A, and the position information PI. Therefore, in the HMD 120B of the HMD set associated with another user, the view image 17F in which the shielding object 8C is arranged between the virtual camera and the shielded object 8A is displayed. Note that the view image 17F may be displayed not on the HMD 120B but on another display device that can be visually recognized by one or more users other than the user 5.

  According to this configuration, when displaying the view image on the own HMD or display device, even if it is not necessary to conceal a specific part of a certain virtual object, it is appropriately concealed from other users. It is possible to

  In the above embodiment, the virtual space (VR space) in which the user is immersed by the HMD has been described as an example, but a transmissive HMD may be adopted as the HMD. In this case, an augmented reality (AR: Augmented Reality) space or a mixed reality (AR) space is output by outputting a view image in which a part of an image constituting the virtual space is synthesized into a real space visually recognized by the user via a transmission-type HMD. A virtual experience in an MR (Mixed Reality) space may be provided to the user. In this case, the action on the target object in the virtual space may be generated based on the movement of the user's hand instead of the operation object. Specifically, the processor may specify the coordinate information of the position of the user's hand in the real space and define the position of the target object in the virtual space in relation to the coordinate information in the real space. Thereby, the processor can grasp the positional relationship between the user's hand in the real space and the target object in the virtual space, and execute a process corresponding to the above-described collision control or the like between the user's hand and the target object. . As a result, it is possible to give an effect to the target object based on the movement of the user's hand.
