[Configuration of HMD system]
A configuration of an HMD (Head-Mounted Device) system 100 will be described with reference to FIG. FIG. 1 schematically shows a configuration of 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, and 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 the HMD set 110. The number of HMD sets 110 constituting the HMD system 100 is not limited to four, and may be three or less or five or more. The HMD set 110 includes an HMD 120, a computer 200, an HMD sensor 410, a display 430, and a 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. The controller 300 can include a motion sensor 420.

  In one aspect, the computer 200 can be connected to the Internet and other networks 2, and can communicate with the server 600 and other computers connected to the network 2. Examples of other computers include computers of other HMD sets 110 and external devices 700. In another aspect, the HMD 120 may include a 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, the HMD 120 displays a right-eye image and a left-eye image on the 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 between both eyes. The HMD 120 can include both a so-called head mounted display including a monitor and a head mounted device to which a terminal having a smartphone or other monitor can be attached.

  The monitor 130 is realized as, for example, a non-transmissive display device. In one aspect, the monitor 130 is disposed on the main body of the HMD 120 so as to be positioned in front of both eyes of the user 5. Therefore, the user 5 can immerse in the virtual space when viewing the three-dimensional image displayed on the monitor 130. 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 one aspect, the monitor 130 can be realized as a liquid crystal monitor or an organic EL (Electro Luminescence) monitor provided in a so-called smartphone or other information display terminal.

  In another aspect, the monitor 130 can be realized as a transmissive display device. In this case, the HMD 120 may be an open type such as a glasses type instead of a sealed type that covers the eyes of the user 5 as shown in FIG. The transmissive monitor 130 may be temporarily configured as a non-transmissive display device by adjusting the transmittance. The monitor 130 may include a configuration that simultaneously displays a part of an image constituting the virtual space and the real space. For example, the monitor 130 may display a real space image taken by a camera mounted on the HMD 120, or may make the real space visible by setting a part of the transmittance high.

  In one aspect, the monitor 130 may include a sub-monitor for displaying an image for the right eye and a sub-monitor for displaying an image for the left eye. In another aspect, the monitor 130 may be configured to display a right-eye image and a left-eye image together. 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 rays. The HMD sensor 410 has a position tracking function for detecting the movement of the HMD 120. More specifically, the HMD sensor 410 reads a plurality of infrared rays emitted from the HMD 120 and detects the position and inclination of the 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 inclination of the HMD 120 by executing image analysis processing using image information of the HMD 120 output from the camera.

  In another aspect, the HMD 120 may include a sensor 190 instead of the HMD sensor 410 or in addition to the HMD sensor 410 as a position detector. 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 using any one 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 angular velocities around the three axes of the HMD 120 in real space over time. The HMD 120 calculates the temporal change of the angle around the three axes of the HMD 120 based on each angular velocity, and further calculates the inclination of the HMD 120 based on the temporal change of the angle.

  The gaze sensor 140 detects the 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, the gaze sensor 140 preferably includes a right eye sensor and a left eye sensor. The gaze sensor 140 may be, for example, a sensor that irradiates the right eye and left eye of the user 5 with infrared light and detects the rotation angle of each eyeball by receiving reflected light from the cornea and iris with respect to the irradiated light. . The gaze sensor 140 can detect the line of sight of the user 5 based on each detected rotation angle.

  The first camera 150 captures the lower part of the face of the user 5. More specifically, the first camera 150 photographs the nose and mouth of the user 5. The second camera 160 photographs the eyes and eyebrows of the user 5. The housing on the user 5 side of the HMD 120 is defined as the inside of the HMD 120, and the housing on the opposite side to the user 5 of the HMD 120 is defined as the outside of the HMD 120. In one aspect, the first camera 150 may be disposed outside the HMD 120 and the second camera 160 may be disposed inside the HMD 120. 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 a single camera, and the face of the user 5 may be photographed with the single camera.

  The microphone 170 converts the utterance of the user 5 into an audio signal (electrical signal) and outputs it to the computer 200. The speaker 180 converts the sound signal into sound and outputs the sound 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 wireless. The controller 300 receives input of commands from the user 5 to the computer 200. In one aspect, the controller 300 is configured to be gripped by the user 5. In another aspect, the controller 300 is configured to be attachable to the body of the user 5 or a part of clothing. 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 yet another aspect, the controller 300 receives an operation from the user 5 for controlling the position and movement of an object arranged in the virtual space.

  In one aspect, the controller 300 includes a plurality of light sources. Each light source is realized by, for example, an LED that emits infrared rays. 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 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 tilt of the controller 300 by executing image analysis processing using the image information of the controller 300 output from the camera.

  In a certain aspect, the motion sensor 420 is attached to the hand of the user 5 and detects the movement of the user 5 hand. For example, the motion sensor 420 detects the rotation speed, the number of rotations, 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 the controller 300 configured to be gripped by the user 5, for example. In another aspect, for safety in real space, the controller 300 is attached to something that does not fly easily by being attached to the hand of the user 5 such as a glove shape. In yet another aspect, a sensor that is not worn by the user 5 may detect the movement of the user's 5 hand. 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. As an example, the motion sensor 420 and the computer 200 are connected to each other wirelessly. In the case of wireless communication, the communication form is not particularly limited, and for example, Bluetooth (registered trademark) or other known communication methods are used.

  Display 430 displays an image similar to the image displayed on monitor 130. Thereby, a user other than the user 5 wearing the HMD 120 can view the same image as that of the user 5. The image displayed on the display 430 need not be a three-dimensional image, and 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.

  Server 600 may send a program to computer 200. In another aspect, the server 600 may communicate with other computers 200 for providing virtual reality to the 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 each user's operation with another computer 200 via the server 600, and the plurality of users in the same virtual space. Users can enjoy a common game. Each computer 200 may communicate a signal based on each user's operation with another computer 200 without passing through the server 600.

  The external device 700 may be any device that can communicate with the computer 200. For example, the external device 700 may be a device that can communicate with the computer 200 via the network 2, or may be a device that can directly communicate with the computer 200 by short-range wireless communication or wired connection. Examples of the external device 700 include, but are not limited to, a smart device, a PC (Personal Computer), and a peripheral device of the computer 200.

[Computer hardware configuration]
A computer 200 according to the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing 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 given to the computer 200 or based on a predetermined condition being satisfied. 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 other 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 the computer 200 and data generated by the processor 210. In one aspect, the memory 220 is realized as a RAM (Random Access Memory) or other volatile memory.

  The storage 230 permanently holds programs and data. The storage 230 is realized as, for example, a ROM (Read-Only Memory), a hard disk device, a flash memory, and other nonvolatile storage devices. 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 and objects for defining a virtual space.

  In another aspect, the storage 230 may be realized as a removable storage device such as a memory card. In yet another aspect, instead of the storage 230 built in the computer 200, a configuration using a program and data stored in an external storage device may be used. According to such a configuration, for example, in a scene 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, the input / output interface 240 may further communicate with the 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 command output from the processor 210 to the controller 300. The instruction instructs the controller 300 to vibrate, output sound, emit light, and the like. When the controller 300 receives the command, the controller 300 executes vibration, sound output, or light emission according to the command.

  The communication interface 250 is connected to the network 2 and communicates with other computers (for example, the server 600) connected to the network 2. In one aspect, the communication interface 250 is, for example, a LAN (Local Area Network) or other wired communication interface, or a WiFi (registered trademark), Bluetooth (registered trademark), NFC (Near Field Communication), or other wireless communication interface. Realized as a communication interface. 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 that can be executed 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. The HMD 120 displays an image on the monitor 130 based on the signal.

  In the example shown in FIG. 2, a configuration in which the computer 200 is provided outside the HMD 120 is shown. 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 be configured to be used in common for 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 other users in the same virtual space.

  In an 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, the horizontal direction orthogonal to the vertical direction, and the front-rear direction orthogonal to both the vertical direction and the horizontal direction. The horizontal direction, vertical direction (vertical direction), and front-rear direction in the real coordinate system are defined as an x-axis, a y-axis, and a 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-rear direction of the real space.

  In one aspect, HMD sensor 410 includes an infrared sensor. When the infrared sensor detects the 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 inclination (orientation) 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). To do. More specifically, the HMD sensor 410 can detect temporal changes in the position and 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 the 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 the 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 the uvw visual field coordinate system set in HMD 120 according to an embodiment. The HMD sensor 410 detects the position and inclination of the HMD 120 in the real coordinate system when the HMD 120 is activated. The processor 210 sets the uvw visual field coordinate system to the HMD 120 based on the detected value.

  As shown in FIG. 3, the HMD 120 sets a three-dimensional uvw visual field coordinate system with the head (origin) of the user 5 wearing the HMD 120 as the center (origin). More specifically, the HMD 120 includes a horizontal direction, a vertical direction, and a front-rear direction (x-axis, y-axis, z-axis) that define the real coordinate system by an inclination around each axis of the HMD 120 in the real coordinate system. Three directions newly obtained by tilting around the axis are set as the pitch axis (u-axis), yaw axis (v-axis), and 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 stands upright and is viewing the front, the processor 210 sets the uvw visual field coordinate system parallel to the real coordinate system to the HMD 120. In this case, the horizontal direction (x-axis), vertical direction (y-axis), and front-rear direction (z-axis) in the real coordinate system are the pitch axis (u-axis) and yaw axis (v-axis) of the uvw visual field coordinate system in the HMD 120. , And the roll axis (w axis).

  After the uvw visual field coordinate system is set to the HMD 120, the HMD sensor 410 can detect the inclination of the HMD 120 in the set uvw visual field 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 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) represents the inclination angle of the HMD 120 around the roll axis in the uvw visual field coordinate system.

  The HMD sensor 410 sets the uvw visual field coordinate system in the HMD 120 after the HMD 120 moves based on the detected inclination of the HMD 120 in 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 inclination of the HMD 120 change, the position and inclination of the uvw visual field coordinate system of the HMD 120 in the real coordinate system change in conjunction with the change of the position and inclination.

  In one aspect, the HMD sensor 410 uses the HMD 120 based on the infrared light intensity 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 visual field 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 aspect of expressing virtual space 11 according to an embodiment. The virtual space 11 has a spherical shape that covers the entire 360 ° direction of the center 12. In FIG. 4, the upper half of the celestial sphere in the virtual space 11 is illustrated 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 coordinate values in an XYZ coordinate system that is a global coordinate system defined in the virtual space 11. The computer 200 associates each partial image constituting the panoramic image 13 (still image, moving image, etc.) that can be developed in the virtual space 11 with each corresponding mesh in the virtual space 11.

  In one aspect, the virtual space 11 defines an XYZ coordinate system with the center 12 as the origin. The XYZ coordinate system is, for example, parallel to the real coordinate system. The horizontal direction, vertical direction (up and down direction), and front and rear 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 XYZ coordinate system The Z axis (front-rear 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 disposed 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, changes in the position and inclination of the HMD 120 in the real space can be similarly reproduced in the virtual space 11.

  As with the HMD 120, the uvw visual field coordinate system is defined for the virtual camera 14. The uvw visual field coordinate system of the virtual camera 14 in the virtual space 11 is defined so as to be interlocked with the uvw visual field 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 field-of-view area 15 in the virtual space 11 based on the position and tilt (reference line of sight 16) of the virtual camera 14. The visual field area 15 corresponds to an area of 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 a direction in the viewpoint coordinate system when the user 5 visually recognizes the object. The uvw visual field coordinate system of the HMD 120 is equal to the viewpoint coordinate system when the user 5 visually recognizes the monitor 130. The uvw visual field coordinate system of the virtual camera 14 is linked to the uvw visual field 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 line of sight]
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 one aspect, 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 line-of-sight detection result, the computer 200 identifies the point of sight N1 that is the intersection of the lines of sight R1 and L1 based on the detection value. On the other hand, when the detected values of the lines of sight R2 and L2 are received from the gaze sensor 140, the computer 200 specifies the intersection of the lines of sight R2 and L2 as the point of sight. The computer 200 specifies the line of sight N0 of the user 5 based on the specified position of the gazing point N1. For example, the computer 200 detects, as the line of sight N0, the extending direction of 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 pointing the 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 with respect to the view field area 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 field-of-view area 15 will be described with reference to FIGS. FIG. 6 is a diagram illustrating a YZ cross section of the visual field region 15 as viewed from the X direction in the virtual space 11. FIG. 7 is a diagram illustrating an XZ cross section of the visual field region 15 as viewed from the Y direction in the virtual space 11.

  As shown in FIG. 6, the field-of-view region 15 in the YZ section includes a region 18. The region 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 field-of-view region 15 in the XZ section includes a region 19. The region 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 angle 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 (orientation) 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 visual field image 17 is an image corresponding to a portion corresponding to the visual field region 15 in the panoramic image 13. When the user 5 moves the HMD 120 worn on the head, the virtual camera 14 also moves in conjunction with the movement. As a result, the position of the visual field 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 that is superimposed on the view region 15 in the direction in which the user 5 faces in the virtual space 11 in the panoramic image 13. The user 5 can visually recognize a desired direction in the virtual space 11.

  Thus, the inclination of the virtual camera 14 corresponds to the line of sight of the user 5 (reference line of sight 16) in the virtual space 11, 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 tilt 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 give the user 5 a high sense of immersion in the virtual space 11.

  In one aspect, the processor 210 can 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 region (view region 15) projected on the monitor 130 of the HMD 120 based on the position and inclination of the virtual camera 14 in the virtual space 11.

  In one aspect, the 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 in 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 concerning this indication is illustrated as what is constituted.

  In the state of FIG. 12 (B), the user 5A can communicate with the user 5B through the virtual space 11A through communication (communication). More specifically, the voice of the user 5A acquired by the microphone 170A is transmitted to the HMD 17120B of the user 5B via the server 600 and output from the speaker 180B provided in the HMD 120B. The voice of the user 5B is transmitted to the HMD 120A of the user 5A via the server 600, and is output from the speaker 180A provided in the HMD 120A.

  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 operation 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 in the same manner as the HMD sets 110A, 110B, and 110C. In the following description, A is added to the reference symbol of each component relating to the HMD set 110A, B is added to the reference symbol of each component relating to the HMD set 110B, and C is assigned to the reference symbol of each component relating to the HMD set 110C. It is assumed that D is added to the reference symbol of each component relating 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 related to the avatar such as motion information, face tracking data, and voice data. The motion information includes information indicating temporal changes in the position and inclination of the HMD 120A, information indicating the motion of the hand of the user 5A detected by the motion sensor 420A and the like. The face tracking data includes data that specifies 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 voice data includes data indicating the voice of the user 5A acquired by the microphone 170A of the HMD 120A. The avatar information may include information for specifying the avatar object 6A or the user 5A associated with the avatar object 6A, information for specifying the virtual space 11A in which the avatar object 6A exists, and the like. User ID is mentioned as information which specifies avatar object 6A and user 5A. Room ID is mentioned as information which specifies 11 A of virtual spaces 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, similarly to the process in step S1310A. Similarly, in step S1310C, the processor 210B in the HMD set 110B acquires avatar information for determining the operation of the avatar object 6C in the virtual space 11C and transmits it 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 avatar information of all users (users 5A to 5C in this example) 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. Thereby, a synchronous process is performed. With such synchronization processing, the HMD set 110A, the HMD set 110B, and the HMD 11020C can share each other's avatar information at substantially the same timing.

  Subsequently, based on the avatar information transmitted from the server 600 to the HMD sets 110A to 110C, the HMD sets 110A to 110C execute the processes 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 avatar objects 6C of the other users 5B and 5C in the virtual space 11A. Specifically, the processor 210A updates the position and orientation 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 210 </ b> A updates information (position and orientation, etc.) of the avatar object 6 </ b> B included in the object information stored in the memory module 530. Similarly, the processor 210A updates the information (position, orientation, etc.) 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 of the avatar objects 6A and 6C of the users 5A and 5C in the virtual space 11B, similarly to the process in step S1330A. Similarly, in step S1330C, the processor 210C in the HMD set 110C updates information on the avatar objects 6A and 6B of the users 5A and 5B in the virtual space 11C.

  The virtual camera control module 1421 arranges the virtual camera 14 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 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.

  The reference line-of-sight specifying module 1423 specifies the reference line of sight 16 based on the output of the sensor 190 or the HMD sensor 410. The reference line-of-sight specifying module 1423 further specifies the line of sight of the user 5 based on the signal from the gaze sensor 140. The face organ detection module 1424 detects organs (for example, mouth, eyes, eyebrows) constituting the face of the user 5 from the images of the face of the user 5 generated by the first camera 150 and the second camera 160. The motion detection module 1425 detects the motion (shape) of each organ detected by the face organ detection module 1424.

  The virtual space definition module 1426 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 1427 generates an object placed in the virtual space 11. The objects may include, for example, forests, mountains and other landscapes, animals, etc. that are arranged according to the progress of the game story.

  The operation object control module 1428 arranges an operation object for accepting a user operation in the virtual space 11 in the virtual space 11. For example, the user operates an object placed in the virtual space 11 by operating the operation object. In one aspect, the operation object may include, for example, a hand object corresponding to the hand of the user wearing the HMD 120. In one aspect, the operation object may correspond to a hand portion of the avatar object 6.

  The avatar control module 1429 generates data for placing an avatar object of a user of another computer 200 connected via the network 2 in the virtual space 11. In one aspect, the avatar control module 1429 generates data for arranging the avatar object of the user 5 in the virtual space 11. In one aspect, the avatar control module 1429 generates an avatar object that imitates the user 5 based on the image including the user 5. In another aspect, the avatar control module 1429 displays, in the virtual space 11, an avatar object that 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). Generate data for placement.

  The avatar control module 1429 reflects the movement of the HMD 120 detected by the HMD sensor 410 on the avatar object. For example, the avatar control module 1429 detects that the HMD 120 is tilted and generates data for tilting and arranging the avatar object. In one aspect, the avatar control module 1429 reflects the movement of the controller 300 on the avatar object. In this case, the controller 300 includes a motion sensor for detecting the movement of the controller 300, an acceleration sensor, or a plurality of light emitting elements (for example, infrared LEDs). The avatar control module 1429 reflects the movement of the facial organ detected by the motion detection module 1425 on the face of the avatar object arranged in the virtual space 11. That is, the avatar control module 1429 reflects the movement of the face of the user 5 on the avatar object.

  The control module 510 detects the collision when each of the objects arranged in the virtual space 11 collides with another object. The control module 510 can detect, for example, the timing when a certain object and another object touch each other, and performs a predetermined process when the detection is performed. The control module 510 can detect the timing when the object is away from the touched state, and performs a predetermined process when the detection is made. The control module 510 can detect that the object is touching the object. 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 spatial information 1431, object information 1432, user information 1433, and face information 1434.

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

  The object information 1432 holds content played in the virtual space 11, objects used in the content, and information (for example, position) for arranging the objects in the virtual space 11. The content can include, for example, content representing a scene similar to a game or a real society.

  The user information 1433 includes dimension data 1439. The dimension data 1439 represents the dimension of the body of the user 5. Details of the dimension data 1439 will be described later. The user information 1433 further holds information for identifying the user 5, a program for causing the computer 200 to function as a control device of the HMD system 100, an application program that uses each content held in the object information 1432, and the like. Yes.

  The face information 1434 holds a template stored in advance for the face organ detection module 1424 to detect the face organ of the user 5. In one aspect, the face information 1434 holds a mouth template 1435, an eye template 1436, and an eyebrow template 1437. Each template may be an image corresponding to an organ constituting the face. For example, the mouth template 1435 may be an image of the mouth. Each template may include a plurality of images.

[Technology]
FIG. 15 is a diagram illustrating an outline of processing according to an embodiment. In the example shown in FIG. 15, the user 5A intends to distribute a video including an avatar reflecting his / her movement to the user 5B.

  The user 5A wears the HMD 120A and holds the right controller 300RA and the left controller 300LA. The HMD 120A includes a sensor 190 that functions as a motion sensor. Each controller includes a motion sensor 420.

  The user 5A further wears motion sensors 1521 to 1523. The motion sensor 1521 is attached to the waist of the user 5A by a belt 1531. The motion sensor 1522 is attached to the back of the right foot of the user 5A. The motion sensor 1523 is mounted on the left instep of the user 5A. These motion sensors 1521 to 1523 are connected to the computer 200A by wire or wirelessly.

  In one aspect, the motion sensor attached to the user 5A detects the arrival time and angle of a signal (for example, an infrared laser) emitted from a base station (not shown). The processor 210A of the computer 200A detects the position of the motion sensor with respect to the base station based on the detection result of the motion sensor. The processor 210A may further normalize the position of the motion sensor with respect to the base station with reference to a predetermined point (for example, the position of the sensor 190 mounted on the head).

  In step S1510, the processor 210A of the computer 200A detects the positions of the head, waist, both hands, and both feet of the user 5A by a motion sensor attached to the user 5A. Hereinafter, the position of the part of the user 5 </ b> A detected by each motion sensor is also referred to as “position information”.

  In step S1520, processor 210A calculates the rotation direction of the joint of user 5A from dimension data 1439A and position information of user 5A acquired in advance.

  In step S1530, processor 210A reflects the rotation direction of the joint calculated in step S1520 on the joint of avatar object 6A arranged in virtual space 11A. Thereby, the movement of the user 5A is reflected in the avatar object 6A.

  In step S1540, processor 210A images avatar object 6A with virtual camera 14A arranged in virtual space 11A. More specifically, the processor 210A generates a visual field image 17A corresponding to the visual field region 15A that is the photographing range of the virtual camera 14A.

  In step S1550, processor 210A distributes video data including avatar object 6A generated by repeating steps S1510 to S1540 to computer 200B.

  In step S1560, processor 210B of computer 200B outputs the received video data to display 430B (or monitor 130B). As a result, the user 5B can visually recognize the video including the avatar object 6A in which the movement of the user 5A is reflected.

  Conventionally, in order to realize motion capture, the user has to wear a number (for example, 26) of motion sensors corresponding to the movable part (bone) of the avatar object. For this reason, there is a problem that the cost for realizing motion capture is high. In contrast, the computer 200A according to the embodiment can reflect the movement of the user 5A on the avatar object 6A by a small number of motion sensors by estimating the rotation direction of the joint of the user 5A. As a result, the user 5A can share the moving image including the avatar reflecting his / her movement with the user 5B more easily than before. Hereinafter, a more specific configuration and processing for realizing such a system will be described.

[Get dimension data]
FIG. 16 is a diagram for explaining a method of acquiring dimension data. FIG. 16A shows a state in which the user 5A is standing up facing both front and both hands horizontally. Hereinafter, the state shown in FIG. 16A is also referred to as a first posture. FIG. 16B shows a state in which the user 5A stands up with the front facing and both hands down on the thigh side. Hereinafter, the state illustrated in FIG. 16B is also referred to as a second posture.

  In one aspect, the processor 210A prompts the user 5A to take the first posture and the second posture. As an example, the processor 210A displays the characters of the first posture and the second posture on the monitor 130A, and displays a message indicating that the same posture is taken. As another example, the processor 210A may output a sound indicating that the first posture and the second posture are taken from the speaker 180A.

  The processor 210A acquires positional information of the head, waist, both hands, and both feet of the user 5A in each of the two postures (first posture and second posture) based on the output of the motion sensor worn by the user 5A. . These pieces of position information can be acquired as positions in the real coordinate system (x, y, z) as shown in FIG.

  The processor 210A calculates the dimension data 1439A of the user 5A from the position information corresponding to the two postures. In an embodiment, as shown in FIG. 18, the processor 210A calculates the height, shoulder width, arm length, foot length, and head-to-shoulder height of the user 5A as dimension data 1439A. The processor 210A may calculate the distance between both hands in the second posture as the shoulder width. The processor 210A may calculate half the value obtained by subtracting the shoulder width from the distance between both hands in the first posture as the arm length. The processor 210A may calculate the distance from the foot height to the head height as the height. The processor 210A may calculate the distance from the foot height to the waist height as the foot length. The processor 210A may calculate the height from the height of the hand to the head in the first posture as the height from the head to the shoulder.

  FIG. 19 is a flowchart showing processing for acquiring the dimension data 1439. In step S1910, the processor 210 places the virtual camera 14 in the virtual space 11. The processor 210 further outputs a view field image 17 corresponding to the shooting range of the virtual camera 14 to the monitor 130.

  In step S1920, processor 210 instructs user 5 to assume the first posture. For example, the processor 210 implements the process of step S1920 by placing an object with the instruction in the virtual space 11. In step S1930, processor 210 acquires position information corresponding to the first posture.

  In step S1940, processor 210 instructs user 5 to assume the second posture. In step S1950, processor 210 acquires position information corresponding to the second posture.

  In step S1960, processor 210 calculates size data of user 5 from position information corresponding to the first attitude and position information corresponding to the second attitude. The processor 210 stores the dimension data in the storage 230.

  Based on the above, the user 5 can easily input his / her dimensions to the computer 200 only by taking two postures. In another aspect, the user may input his / her dimensions into the computer 200 using an input device such as a keyboard.

[Rotation direction of joint]
In an embodiment, the computer 200 estimates the rotation direction of the joint of the user 5 based on the outputs (position information) of the six motion sensors attached to the user 5 and the dimension data 1439. As an example, the computer 200 estimates the position of the shoulder based on the position information of the head, the shoulder width, and the height from the head to the shoulder. The computer 200 estimates the elbow position from the shoulder position and the hand position information. This estimation can be performed by a known application utilizing Inverse Kinematics.

  In an embodiment, the computer 200 obtains the inclination (rotation direction) of the joints of the user 5's neck (head), waist, both wrists, and both ankles from the six motion sensors. In addition, the computer 200 estimates the rotational directions of the joints of both shoulders, both elbows, both hips (foot bases), and both knees based on inverse kinematics. As shown in FIG. 20, the computer 200 acquires or estimates the rotation direction of each joint in the uvw visual field coordinate system.

  When the rotation direction is calculated based on the position information and the dimension data, the computer 200 indicates that the user 5 is not facing the front (that is, the head and the waist are facing different directions). The position of the shoulder cannot be estimated accurately. Therefore, in another embodiment, the computer 200 may estimate the rotation direction of the joint in consideration of the inclination of the part of the user 5 detected by the motion sensor. For example, the computer 200 estimates the position of the shoulder based on the positional information of the head, the tilt of the head, the tilt of the waist, the shoulder width, and the height from the head to the shoulder. According to this configuration, the computer 200A can improve the accuracy of the rotation direction of the joint.

[Distribution of video including avatar]
FIG. 21 is a flowchart illustrating an example of processing in which the computer 200 distributes a video including the avatar object 6 reflecting the movement of the user 5.

  In step S2110, processor 210 of computer 200 changes the position and tilt of virtual camera 14 based on the input of user 5. Thereby, the user 5 can photograph the avatar object 6 from an arbitrary position and angle.

  In the above description, the virtual camera 14 is configured to be interlocked with the movement of the HMD 120. However, the HMD 120 and the virtual camera 14 may be configured not to be interlocked during execution of the processing illustrated in FIG. .

  The processor 210 further outputs the view image 17 corresponding to the shooting range of the virtual camera 14 to the monitor 130 of the HMD 120. In other aspects, processor 210 may output view image 17 to display 430. In such a case, the user 5 may wear a motion sensor on the head instead of the HMD 120.

  In step S2120, processor 210 acquires current position information from the six motion sensors attached to user 5 associated with computer 200.

  In step S2130, processor 210 calculates (estimates) the rotation direction of the current joint of user 5 based on the current position information and dimension data 1439.

  In step S2140, processor 210 moves avatar object 6 arranged in virtual space 11 based on the rotation direction obtained by the estimation and the rotation direction obtained from the motion sensor. For example, the processor 210 moves the upper right arm of the avatar object 6 based on the rotation direction of the right shoulder. The processor 210 further moves the position of the avatar object 6 in the virtual space 11 based on the current position information (for example, current position information of the waist). Thereby, the movement of the user 5 in the real space is reflected in the avatar object 6 in the virtual space.

  In step S2150, processor 210 receives an instruction to start recording from the user. In response to this instruction, the processor 210 continuously saves the view image 17 corresponding to the shooting range of the virtual camera 14 in the memory 220 or the storage 230. Thereby, the processor 210 generates video data including the avatar object 6 in which the movement of the user 5 is reflected (step S2160). At this time, the processor 210 may also store the voice of the user 5 acquired from the microphone 170.

  In step S2170, processor 210 accepts an instruction to end recording from the user. In response to this, the processor 210 stops storing the video data.

  In step S2180, processor 210 uploads the video data to server 600 that functions as a video sharing server. The viewer can view the uploaded video data by accessing the server 600.

  In this way, the user 5 can more easily share the moving image including the avatar reflecting his / her movement than before. In another aspect, the processor 210 may directly distribute the video data to the other computer 200 without passing through the server 600.

[When the server generates video]
In the example of FIG. 21, the computer 200 performs a process of generating an image including an avatar. However, the process may be executed by the server 600 instead of the computer 200. FIG. 22 is a flowchart illustrating an example of processing in which the server 600 generates an image including an avatar.

  In step S 2210, processor 610 of server 600 acquires dimension data 1439 of user 5 from computer 200.

  In step S2220, processor 210 of computer 200 transmits current position information acquired from the motion sensor attached to user 5 to server 600.

  After that, the processor 610 generates an image including an avatar by executing the processes of steps S2130, S2140, and S2160 described above. At this time, the processor 610 may execute processing for changing the position and tilt of the virtual camera 14 based on an instruction from the computer 200.

  In step S2230, processor 610 transmits the image including the avatar to computer 200. In step S2240, processor 210 displays the received video on display 430. Thereby, the user 5 can visually recognize the avatar object 6 in which his / her movement is reflected.

  In step S2250, processor 210 transmits a recording start instruction to server 600. In step S2260, processor 610 starts storing video in memory 620 or storage 630 in response to receiving the recording start instruction.

  In step S2270, processor 210 transmits a recording end instruction to server 600. In step S2280, processor 610 ends the storage of the video in response to receiving the recording end instruction.

  According to the above, complicated processing such as processing for moving an avatar based on position information is executed by the server 600. Therefore, even when the processing capability of the computer 200 is low, the user 5 can easily share a video including the avatar object 6 in which his / her movement is reflected.

[Select avatar object]
In the above example, the distributor himself / herself determines the type of the avatar object 6 that reflects the movement of the user 5 who is the distributor of the moving image. However, some viewers want to determine the type of avatar object that reflects the movements of others. Therefore, the server 600 according to an embodiment reflects the movement of the distributor in the avatar object selected by the viewer.

  FIG. 23 is a flowchart illustrating an example of processing of the computer 200 functioning as a viewer terminal. In the example shown in FIG. 23, the server 600 receives content data from another computer 200 that functions as a distributor's terminal, and stores the content data in the storage 630 in advance.

  The content data includes a panoramic image 13 developed in the virtual space 11, data for generating an object arranged in the virtual space 11, and a position information group representing a distributor's movement (that is, a motion sensor attached to the distributor). Continuous output), distributor dimension data 1439, and audio data.

  In step S2310, processor 610 of server 600 transmits to computer 200 a plurality of pieces of content specifying data (for example, thumbnail images of panoramic image 13 included in the content data, content titles, etc.) for specifying the content.

  In step S2320, processor 210 of computer 200 displays the received plurality of content specifying data on display 430. The user 5 (viewer) sees this and selects any one content. The processor 210 transmits the identification information of the selected content to the server 600.

  In step S2330, processor 610 transmits size data, position information group, and audio data associated with the selected content to computer 200. Note that the computer 200 may have acquired in advance dimension data associated with content (that is, dimension data of a content distributor). Therefore, in an embodiment, the processor 610 may transmit the distributor's identification information to the computer 200, and the computer 200 may acquire (specify) the distributor's dimension data based on the identification information.

  In step S2340, processor 210 accepts selection of the type of avatar object 6 from user 5. As an example, the user can select an arbitrary avatar object from among a male avatar object, a female avatar object, an animal avatar object, an avatar object imitating a popular character, and the like.

  Subsequently, the processor 210 executes the processes of steps S2130, S2150, and S2160 described above, and is the avatar object 6 selected by the user 5 (viewer) and reflects the movement of the distributor. A video including the avatar object 6 can be generated.

  In step S2360, processor 210 outputs the generated video to display 430 (or monitor 130) and outputs received audio data from speaker 180.

  According to this configuration, the viewer can reflect the movement of the distributor on any avatar object. For example, if the distributor is an instructor, the instructor records a lesson while wearing a motion sensor. The viewer can enjoy the lesson by watching a video including an arbitrary avatar object reflecting the movement of the lecturer.

  In an embodiment, the computer 200 or the server 600 may make a specific avatar object selectable when a predetermined condition is satisfied (for example, when billing processing is executed).

  In an embodiment, the content data may include information on the rotation direction of the distributor's joint instead of the position information group. In such a case, the viewer's computer 200 does not know how the center of gravity position of the distributor has moved. Therefore, the computer 200 can reflect the movement of the distributor's joint on the avatar object 6 arranged at a predetermined position (for example, the center 12) in the virtual space 11 or the avatar object 6 moving along a predetermined route.

  As another method of reflecting past movements of the distributor in the specific avatar object 6, it is considered to store the position information group of the distributor corresponding to the movable part (bone) of the specific avatar object 6 as content data. It is done. However, in this method, the size of the content data is increased. In addition, the viewer's computer 200 must standardize the position information group based on the size of the specific avatar object 6 and the size data 1439 of the distributor.

  On the other hand, content data including information on the rotation direction of the distributor is smaller in size than content data including the position information group of the distributor. Further, the viewer's computer 200 may not be normalized with respect to the rotation direction. As a result, the viewer's computer 200 can easily share the moving image including the avatar object 6 in which the movement of the distributor is reflected.

[Augmented reality]
In the above embodiment, the viewer visually recognizes that the avatar object 6 arranged in the virtual space 11 performs the same movement as the distributor. In the embodiment described below, the viewer visually recognizes that the avatar object 6 placed in the real space (the corresponding moving image) performs the same movement as the distributor.

  FIG. 24 is a diagram illustrating an outline of processing according to an embodiment. In the example shown in FIG. 24, the computer 200B with which the user 5B is associated functions as a portable information processing terminal (for example, a smartphone). The computer 200B further includes a camera 2431, a motion sensor 2433, and a display 2435.

  In the state (A) of FIG. 24, the user 5B images the rabbit 2421 with the camera 2431 mounted on the computer 200B. The computer 200B outputs the generated moving image to the display 2435. The computer 200B further transmits the moving image generated by the camera 2431 to the computer 200A.

  In the state (B) of FIG. 24, the computer 200A displays the received moving image on the monitor 130A of the HMD 120A. Thereby, the user 5A visually recognizes the rabbit 2421 photographed by the user 5B.

  The user 5A wears the HMD 120A and holds the right controller 300RA and the left controller 300LA. The user 5A further wears motion sensors 1521 to 1523.

  The user 5A speaks while moving while visually recognizing the received moving image. As an example, the user 5A utters “Please gently stroke the back of the rabbit” while making a gesture of touching the rabbit 2421.

  The computer 200A transmits a position information group corresponding to the gesture of the user 5A, audio data, and dimension data 1439 of the user 5A to the computer 200B.

  In the state (C) of FIG. 24, the computer 200B arranges the virtual camera 14B and the avatar object 6A corresponding to the user 5A in the virtual space 11B. The computer 200B acquires the rotation direction of the joint of the user 5A based on the received position information group and the dimension data 1439 (the process in step S2130 described above). The computer 200B further moves the avatar object 6A based on the rotation direction of the joint and the position information (the process in step S2140 described above).

  The computer 200B changes the position and tilt of the virtual camera 14B based on the output of the motion sensor 2433 (the position and tilt of the computer 200B). The computer 200B generates a visual field image 17B corresponding to the visual recognition area 15B that is the photographing range of the virtual camera 14B. In one aspect, the virtual camera 14B is set to capture only the avatar object 6A. In another aspect, objects other than the avatar object 6A arranged in the virtual space 11B (for example, a ground object on which the avatar object 6A stands) and the panoramic image 13B developed in the virtual space 11B may be set to be transparent. . As a result, the computer 200B can generate an image obtained by photographing the avatar object 6A reflecting the movement of the user 5A from an arbitrary position and angle.

  In the state (D) of FIG. 24, the computer 200B detects a plane in a moving image generated by the camera 2431 (that is, a moving image corresponding to the real space). This process can be realized by a known application (for example, ARkit).

  The computer 200B superimposes the video of the avatar object 6A on the detected plane and outputs the superimposed moving image to the display 2435. Thereby, the user 5B can feel as if the avatar object 6A is moving on the plane. The computer 200B further outputs the received audio data.

  According to this configuration, the computer 200B can add the avatar object 6A reflecting the movement of the user 5A to the real world information in real time. Thereby, for example, the user 5A can give an easy-to-understand instruction to the user 5B with gestures for matters that the user 5B is in trouble in the real world. As another example, the user 5B can photograph a sightseeing spot, and the user 5A can virtually report the sightseeing spot.

[Control structure]
FIG. 25 is a flowchart illustrating an example of processing in which the computer 200B outputs an image including the avatar object 6A in which the movement of the user 5A is reflected.

In step S2510, processor 210B of computer 200B transmits an image generated by photographing by camera 2431 to computer 200A. In step S2520, processor 210B accepts selection of the type of avatar object 6A from user 5B.

  In step S2530, processor 210A of computer 200A displays the image on monitor 130A or display 430A. In step S2540, processor 210A transmits dimension data 1439A of user 5A acquired in advance to computer 200B. In step S2550, processor 210A acquires the current position information from the motion sensor attached to user 5A. The processor 210A further acquires audio data from the microphone 170A. The processor 210A transmits the current position information and audio data to the computer 200B.

  Thereafter, the processor 210B generates the avatar object 6A in which the movement of the user 5A is reflected by executing the processes of the above-described steps S2130 and S2140.

  In step S2560, processor 210B changes the position and inclination of virtual camera 14B arranged in virtual space 11B based on the output of motion sensor 2433. For example, the processor 210B arranges the virtual camera 14B at a predetermined position (for example, the center 12B) in the virtual space 11B. The processor 210B reflects changes in the position and tilt of the computer 200B calculated from the output of the motion sensor 2433 in the position and tilt of the virtual camera 14B.

  In step S2570, processor 210B images avatar object 6A with virtual camera 14B.

  In step S2580, processor 210B superimposes the avatar object 6A photographed by virtual camera 14B on the image photographed by camera 2431. The processor 210B outputs an image on which the avatar object 6A is superimposed on the display 2435. The processor 210B further outputs the received audio data.

  The computer 200A and the computer 200B repeatedly execute the processes shown in FIG. 25 except for steps S2520 and S2540. As a result, the avatar object 6A reflecting the movement of the user 5A appears in the real world displayed on the display 2435.

  In the example shown in FIG. 25, the computer 200A and the computer 200B directly transmit / receive information, but the information may be transmitted / received via the server 600.

  In the example shown in FIG. 25, the computer 200B is configured to execute the process of step S2130 (a process of estimating the rotation direction), but the execution subject of the process is not limited to the computer 200B. For example, the server 600 may estimate the rotation direction as in the process shown in FIG. 22, or the computer 200A may estimate the rotation direction. The computer 200A may transmit the current position information and the estimation result of the rotation direction to the computer 200B, or only the estimation result of the rotation direction when the avatar object 6A does not reflect the movement of the center of gravity of the user 5A as described above. May be transmitted to the computer 200A.

  In the example shown in FIG. 25, the computer 200A transmits the dimension data 1439A to the computer 200B in step S2540. However, the computer 200B may acquire the dimension data 1439A in advance. In that case, the computer 200A can transmit the identification information of the user 5A or the computer 200A to the computer 200B in step S2540. The computer 200B can specify the dimension data 1439A corresponding to the user 5A according to the received identification information.

  In the above example, the user 5 wears motion sensors at a total of six locations including the head, waist, both hands, and both feet, but the number of motion sensors is not limited to six. The user 5 only needs to attach the motion sensor in at least one place.

[Embodiment 2]
[Automatic acquisition of dimension data]
In the present embodiment, a configuration for automatically acquiring the dimension data described in the above embodiment will be described. FIG. 26 is a diagram for explaining automatic acquisition of dimension data according to an embodiment.

  When the processor 210A executes a program for reflecting the movement of the user 5A on the avatar object 6A arranged in the virtual space, the processor 210A starts automatic acquisition of dimension data. The processor 210A prompts the user 5A to move to a predetermined position (first position). Hereinafter, the predetermined position is referred to as “home position”.

  The home position is preferably specified in the real space so that the user can recognize the home position. FIG. 26A shows an example of a mark that clearly indicates the home position. As an example, the mark 2641 shown in FIG. 26A may be formed by attaching a tape to a surface (such as a floor surface) that comes into contact with the sole of the user 5A when the user 5A stands up.

  As an example of a method for prompting the user 5A to move to the home position, the processor 210A displays a character standing on the same mark as the mark 2641 and a message indicating that the user stands on the mark 2641 on the monitor 130A. As another example, the processor 210A may output a sound of standing on the mark 2641 from the speaker 180A.

  The processor 210A detects that the user 5A is at the home position, that is, the user 5A is standing on the mark 2641. As an example, the detection of the state is realized by the processor 210 </ b> A determining whether or not the position of the head of the user 5 </ b> A is within a range stored in advance in the storage 230. In this case, the position of the head of the user 5A may be detected by tracking the position of the HMD 120A by the HMD sensor 410, or may be detected based on position information detected by a motion sensor included in the HMD 120A. . Further, as the above range, a range centering on the position of the head when the user 5A is standing at the home position may be set.

  When the processor 210A detects that the user 5A is at the home position, the processor 210A prompts the user 5A to take the posture shown in FIG. FIG. 26B illustrates a state in which the user 5A stands up at the home position with the front facing and both hands down on the thigh side. In the first embodiment, the state illustrated in FIG. 26B is referred to as the second posture, but in the present embodiment, the state is referred to as the first posture.

  As an example of a method for prompting the user 5A to take the first posture, the processor 210A displays a character in the first posture and a message indicating that the same posture is taken. As another example, the processor 210A may output a sound indicating the first posture from the speaker 180A.

  In the example shown in FIG. 26, the user 5A wears motion sensors 2651 to 2654 as position sensors in addition to the HMD 120A, the right controller 300RA, the left controller 300LA, and the motion sensors 1521 to 1523. The motion sensors 2651 to 2654 have the same functions as the motion sensors 1521 to 1523. The motion sensor 2651 is attached to the right elbow of the user 5A. The motion sensor 2652 is attached to the left elbow of the user 5A. The motion sensor 2653 is attached to the right knee of the user 5A. The motion sensor 2654 is attached to the left knee of the user 5A.

  The processor 210A detects that the user 5A is in the first posture at the home position. In the present embodiment, “the user 5A is in the first position at the home position” means that the user 5A remains on the mark 2641 while staying in the first position for a predetermined time (for example, 3 seconds). Refers to the state of being. The detection that the user 5A is in the first posture at the home position is realized by the processor 210A specifying this state. Since the method for specifying that the user 5A is at the home position has already been described, the description will not be repeated here.

  As an example, the processor 210A, based on the position information detected by each motion sensor attached to the user 5A, the position information (first position) of the head, waist, both hands, both legs and elbows corresponding to the first posture. Information) is specified (acquired). The first position information can be acquired as a position in the real coordinate system (x, y, z). Subsequently, the processor 210A specifies that the posture of the user 5A is the first posture based on the positional relationship between the parts of the user 5A corresponding to the first posture. Specifically, when the processor 210A specifies that the legs, knees, hands, and elbows of the user 5A are aligned in a direction substantially perpendicular to the surface on which the mark 2641 is formed, the posture of the user 5A is Specify one posture. Then, the processor 210A calculates the acceleration of each part of the user 5A in the first posture. The acceleration can be calculated based on the temporal change of the position information detected by each motion sensor attached to the user 5A. If the acceleration continues for a predetermined time and falls within a predetermined error range, the processor 210A specifies that the user 5A remains stationary for a predetermined time while taking the first posture.

  When detecting the first posture, the processor 210A calculates the dimension data 1439A (see FIG. 18) of the user 5A from the identified first position information. Specifically, the processor 210A calculates the height, shoulder width, and foot length (first dimension data) of the user 5A among the dimension data 1439A shown in FIG. The processor 210A may calculate the distance from the position of one hand to the position of the other hand in the first position information as the shoulder width. Further, the processor 210A can calculate the height from the position of the foot to the position of the head as the height. The processor 210A may calculate the height from the foot position to the waist position as the leg length.

  After calculating the dimension data from the first position information, the processor 210A prompts the user 5A to take the second posture shown in FIG. FIG. 26C illustrates a state in which the user 5A stands up at the home position, facing front, spreading both hands horizontally. In the first embodiment, the state illustrated in FIG. 26C is referred to as a first posture, but in the present embodiment, the state is referred to as a second posture.

  As an example of a method for prompting the user 5A to take the second posture, the processor 210A displays a character in the second posture and a message indicating that the same posture is taken on the monitor 130A. As another example, the processor 210A may output a sound indicating the second posture from the speaker 180A.

  The processor 210A detects that the user 5A is in the second posture at the home position. In the present embodiment, “the user 5A is in the second position at the home position” refers to a state in which the user 5A is on the mark 2641 and is stationary for a predetermined time while maintaining the second position. . The detection that the user 5A is in the second posture at the home position is realized by the processor 210A specifying this state. Since the method for specifying that the user 5A is at the home position has already been described, the description will not be repeated here.

  As an example, the processor 210A, based on the position information detected by each motion sensor attached to the user 5A, the position information (third position) of the head, waist, both hands, both legs and elbows corresponding to the second posture. Information). The third position information can be acquired as a position in the real coordinate system (x, y, z), similarly to the first position information. Subsequently, the processor 210A specifies that the posture of the user 5A is the second posture based on the positional relationship of each part of the user 5A corresponding to the second posture. Specifically, when the processor 210A specifies that both hands and both elbows of the user 5A are aligned in parallel to the surface on which the mark 2641 is formed, the posture of the user 5A is the second posture. Identify. Then, the processor 210A specifies that the user 5A is stationary for a predetermined time while taking the second posture, in the same manner as the above-described identification of being stationary for a predetermined time while taking the first posture. To do.

  When the processor 210A detects the second posture, the processor 210A calculates the dimension data 1439A of the user 5A from the identified first position information and third position information. Specifically, the processor 210A calculates the arm length (second dimension data) of the user 5A in the dimension data 1439A shown in FIG. The processor 210A may calculate the distance from the position of one hand to the position of the other hand in the third position information, and calculate half the value obtained by subtracting the shoulder width from the distance as the arm length. In calculating the length of the arm, the shoulder width calculated based on the first position information can be eliminated, so that more accurate dimension data can be calculated by using the first position information and the third position information. can do.

  In addition, the processor 210A may correct the height and leg length calculated from the first position information based on the third position information. As an example, the processor 210A may calculate the height from the third position information, and may use an average value of the height calculated from the first position information and the height calculated from the third position information as the height of the user 5A. Similarly, the processor 210A calculates the leg length from the third position information, and calculates the average value of the leg length calculated from the first position information and the leg length calculated from the third position information as the user. The leg length may be 5A.

  The content of the dimension data 1439A is not limited to the example shown in FIG. As an example, the dimension data 1439A may further include a length from the hand to the elbow, a length from the elbow to the shoulder, a length from the foot to the knee, a length from the knee to the waist, and the like.

  The processor 210A may calculate the length from the hand to the elbow, the length from the foot to the knee, and the length from the knee to the waist from the first position information. Specifically, the processor 210A may calculate the distance from the right hand position to the right elbow position as the length from the right hand to the right elbow. The processor 210A can similarly calculate the length from the left hand to the left elbow. The processor 210A may calculate the distance from the position of the right foot to the position of the right knee as the length from the right foot to the right knee. The processor 210A can similarly calculate the length from the left foot to the left knee. The processor 210A may calculate the distance from the position of the right knee to the position of the waist as the length from the right knee to the waist. The processor 210A can similarly calculate the length from the left knee to the waist.

  In addition, the processor 210A can calculate the length from the elbow to the shoulder from the first position information and the third position information. Specifically, the processor 210A can calculate a value obtained by subtracting the length from the right hand to the right elbow from the length of the arm as the length from the right elbow to the right shoulder. The processor 210A can similarly calculate the length from the left elbow to the left shoulder.

  The processor 210A may correct the length from the hand to the elbow, the length from the foot to the knee, and the length from the knee to the waist calculated from the first position information based on the third position information. Since this correction method is the same as the above-described method for correcting the height and leg length, description thereof will not be repeated here.

  FIG. 27 is a flowchart showing an automatic acquisition process of dimension data 1439 according to an embodiment. In step S2750, processor 210 executes a program for reflecting the movement of user 5A on avatar object 6A arranged in the virtual space, and arranges virtual camera 14 in virtual space 11. The processor 210 further outputs a view field image 17 corresponding to the shooting range of the virtual camera 14 to the monitor 130.

  In step S2751, the processor 210 instructs the user 5 to stand at the home position. For example, the processor 210 realizes the process of step S2751 by placing an object with the instruction in the virtual space 11.

  In step S2752, the processor 210 detects that the user 5 is in the home position. When the processor 210 detects that the user 5 is in the home position, the processor 210 instructs the user 5 to assume the first posture in step S2753. For example, the processor 210 realizes the process of step S2753 by arranging an object in which the instruction is described in the virtual space 11.

  In step S2754, the processor 210 acquires the first position information and detects that the user 5 is in the first posture. When the processor 210 detects that the user 5 is in the first posture, the processor 210 calculates dimension data from the first position information in step S2755.

  In step S2756, processor 210 instructs user 5 to assume the second posture. For example, the processor 210 realizes the process of step S2756 by arranging an object in which the instruction is described in the virtual space 11.

  In step S2757, the processor 210 acquires the third position information and detects that the user 5 is in the second posture. When the processor 210 detects that the user 5 is in the second posture, the processor 210 calculates dimension data from the first position information and the third position information in step S2758.

  According to the above, when the processor 210 executes the application, the dimension data of the user 5 is automatically acquired. The user 5 need only take two postures at a predetermined position in the real space in order to input his / her dimension data. As described above, the user 5 can easily input the dimension data by one person.

  Further, according to the above, the processor 210 instructs the user 5 to move to the home position, take the first posture, and take the second posture. Thereby, the user 5 can recognize what should be done next in the input of dimension data. As described above, the user 5 can input dimension data more easily by one person.

  The processor 210 acquires the current position information (second position information) corresponding to the user's current posture (third posture) from each motion sensor attached to the user 5 after executing the process of step S2758, The avatar object 6 is controlled based on the current position information and the calculated dimension data. As an example of this control, the processor 210 may move the avatar object 6 so as to take the current posture of the user. Further, the processor 210 may execute the processing shown in the flowchart of FIG. 21 after executing the processing of step S2758.

  According to the above, the user 5 can easily perform not only the input of the dimension data but also the reflection of the movement of the user 5 on the avatar object 6 by one person.

  Further, at the same time as moving the avatar object 6 in step S <b> 2140 shown in FIG. 21, the change in the facial expression of the user 5 may be reflected in the facial expression of the avatar object 6. In this process, a device having a face tracking function is fixed to the front of the face of the user 5 and the captured face image of the user 5 is synchronized with the current position information and rotation direction obtained from the motion sensor with a time stamp. This is realized.

  In addition, the processor 210 calculates the ratio between the dimension data of the user 5 and the dimension data of the avatar object 6 by using the dimension data of the user 5 calculated in steps S2755 and S2758 and the dimension data of the avatar object 6. May be. The processor 210 may use the ratio for controlling the avatar object 6. Even in this way, the processor 210 can control the avatar object 6 in consideration of the difference between the dimension data of the user 5 </ b> A and the dimension data of the avatar object 6. Therefore, when both dimension data differ greatly, for example, even if the avatar object 6 is a two-headed character, the movement of the user 5 can be reflected in the avatar object 6 naturally. Note that the dimension data of the avatar object 6 may be stored in the storage 230 in advance, for example.

  In the example described above, the posture shown in FIG. 26B is the first posture and the posture shown in FIG. 26C is the second posture. However, the posture shown in FIG. The posture shown in FIG. 26B may be set as the second posture.

  The processor 210 may be configured not to execute at least one of the processes of steps S2751, S2753, and S2756 shown in FIG. As an example, the processor 210 may be configured not to execute all the processes of these steps, that is, not to give an instruction to the user 5.

  Further, the processor 210 may be configured not to execute the processes of steps S2756 to S2758 shown in FIG. That is, the processor 210 may be configured to calculate the dimension data of the user 5 based only on the first posture. According to this configuration, the height, shoulder width, leg length, length from the hand to the elbow, length from the foot to the knee, length from the knee to the waist, and the like are acquired as the dimension data of the user 5. Can do. In this example, the first posture may be the posture shown in FIG. In this case, the dimension data of the user 5 includes height, arm length, leg length, head to shoulder height, hand to elbow length, elbow to shoulder length, foot to knee. The length from the knee to the waist can be acquired.

  In the example shown in FIG. 27, the calculation of the dimension data from the first position information (step S2755) and the calculation of the dimension data from the first position information and the third position information (step S2758) are performed respectively. Although described as being performed after the detection of one posture (step S2754) and the detection of the second posture (step S2757), it is not limited to this example. As an example, the dimension data calculation process may be performed at the same timing as the first attitude detection process and the second attitude detection process, respectively. Specifically, the processor 210 may start calculating the dimension data while detecting the first attitude or the second attitude when the first position information or the third position information is acquired. In this example, when the first posture or the second posture cannot be detected, the processor 210 may stop calculating the dimension data. The case where the first posture or the second posture cannot be detected includes, for example, a case where the user 5 is in a posture different from the first posture or the second posture before a predetermined time elapses.

  In the above-described example, the first posture and the second posture are specified based on the first position information and the third position information. However, the specification of the first posture and the second posture is not limited to this method. . For example, the image including the user 5 captured by the camera is compared with the reference image, and if the error of the user 5 in both images is within a predetermined range, the user 5 takes the first posture or the second posture. You may specify that The camera may be provided at a position where the whole body of the user 5 can be photographed and connected to the computer 200 by wire or wireless. In addition, as the reference image, it is only necessary to use an image obtained by photographing the user 5 in the first posture and the second posture in advance. The reference image acquired in advance may be stored in the storage 230. Further, in the example in which the first posture and the second posture are specified by this method, the processor 210 acquires the first position information and the third position information during or after the specification of the first posture and the second posture. That's fine.

  Also, instead of position detection using a motion sensor, motion detection using a high-precision gyro sensor can be used to acquire dimension data and reflect the movement of the user 5 on the avatar object 6. Good.

[Additional Notes]
The technical features disclosed above can be summarized as follows.

  (Item 1) The program for reflecting the movement of the user wearing the position sensor on the avatar arranged in the virtual space has been described. According to an aspect of the present disclosure, the program causes the computer to detect that the user is at the first position (S2752), and when detecting that the user is at the first position, the user takes the first posture. The first dimension of the user based on the first position information corresponding to the first posture acquired from the position sensor when detecting that the first posture is detected (S2754). A step of calculating data (S2755) and a step of controlling the avatar based on the second position information acquired from the position sensor after the calculation of the first dimension data and the first dimension data (S2140) are executed.

And a control unit (processor 210).

  (Item 9) A method for executing a program has been described. According to an aspect of the present disclosure, the program is executed by a computer (200) including a processor (210) and a memory (220). The method is a method in which the processor executes each step according to (Item 1).

In the embodiment described above, the virtual space (VR space) in which the user is immersed by the HMD has been described as an example. However, a transmissive HMD may be adopted as the HMD. In this case, an augmented reality (AR) space or mixed reality (AR) space or mixed reality (AR) is generated by outputting a visual field image obtained by synthesizing a part of an image constituting the virtual space to the real space visually recognized by the user via the transmissive HMD. A virtual experience in an MR (Mixed Reality) space may be provided to the user. In this case, instead of the operation object, an action on the target object in the virtual space may be generated based on the movement of the user's hand. 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. As a result, 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 can execute processing 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 act on the target object based on the movement of the user's hand.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
