Description

  The present disclosure relates to distribution of image data, and more particularly to distribution of image data that can be provided via a head mounted device (HMD).

  A technique for providing image data to a user wearing an HMD and providing a three-dimensional image or 360-degree image in a virtual space is known. A user wearing the HMD can visually recognize an image displayed on the terminal as a three-dimensional image or a 360-degree image. On the other hand, in the case of a user not wearing an HMD, for example, a three-dimensional image or 360-degree image is displayed in a two-dimensional manner on a flat display, and the displayed image is a three-dimensional image or 360-degree image. By displaying characters or icons indicating the effect, these images can be recognized as a planar image by the user. Non-Patent Document 1 displays an image captured in VR (Virtual Reality) as a two-dimensional demo video. Then, the word “VR Demo” indicating that the demo video originally corresponds to virtual reality (VR) is displayed in the title of the demo video. Non-Patent Document 2 discloses a technique in which both a left-eye image and a right-eye image are arranged in a screen on a monitor screen of a terminal.

  Before the moving image disclosed in Non-Patent Document 1 is captured as a two-dimensional demo moving image, the visual field image is updated in conjunction with the movement of the head of the user wearing the HMD. It is expensive. However, it is difficult for a user who browses a two-dimensional demo video on the video distribution site to determine at a glance that the video displayed on the display is a demo video that originally captured VR. In addition, since the moving image disclosed in Non-Patent Document 2 displays the image for the left eye and the image for the right eye on one screen, each image becomes smaller. Therefore, there is a need for a technique that easily recognizes that an image viewed without an HMD is a stereoscopically viewable image.

  The present disclosure has been made in order to solve the above-described problems, and an object in one aspect is that a two-dimensional image is displayed and the image can be stereoscopically viewed. It is to provide a technology that can be easily recognized by a user.

  According to an embodiment, a computer-implemented method for presenting content is provided. In this method, content data capable of presenting content on a display is loaded into a memory of a computer, and a mask image is overlaid on content assumed to be viewed other than two-dimensional display for a user wearing a head mounted device. A step of detecting an instruction to perform, and a step of displaying, on the monitor, content other than content assumed to be a viewing mode other than two-dimensional display in a state where the mask image is overlaid based on detection of the instruction. Including.

  In one aspect, the user can easily recognize that the image is a stereoscopically viewable image in a state where the two-dimensional image is displayed.

[Configuration of HMD system]
A configuration of an HMD (Head Mounted Device) system 100 will be described with reference to FIG. FIG. 1 is a diagram representing an outline of a configuration of an HMD system 100 according to an embodiment. In one aspect, the HMD system 100 is provided as a home system or a business system. In the present embodiment, the HMD may include both a so-called head mounted display including a monitor and a head mounted device on which a terminal having a smartphone or other monitor can be attached.

  The HMD system 100 includes an HMD 110, an HMD sensor 120, a controller 160, and a terminal 200. The HMD 110 includes a monitor 112 and a gaze sensor 140. The controller 160 can include a motion sensor 130.

  In one aspect, the terminal 200 can be connected to the Internet and other networks 19, and can communicate with the server 150 and other computers connected to the network 19. The terminal 200 is an information processing device such as a personal computer, a tablet terminal, or a smartphone, and includes at least a processor, a monitor, and a communication interface.

  In another aspect, instead of the HMD system 100 including the HMD sensor 120, the HMD 110 may include the sensor 114.

  The server 150 includes a processor 151, a memory 152, and a communication interface 153. The server 150 is realized by a computer having a known configuration.

  The HMD 110 may be worn on the user's head and provide a virtual space to the user during operation. More specifically, the HMD 110 displays a right-eye image and a left-eye image on the monitor 112, respectively. When each eye of the user visually recognizes each image, the user can recognize the image as a three-dimensional image based on the parallax of both eyes.

  The monitor 112 is realized as, for example, a non-transmissive display device. In one aspect, the monitor 112 is disposed on the main body of the HMD 110 so as to be positioned in front of both eyes of the user. Therefore, when the user visually recognizes the three-dimensional image displayed on the monitor 112, the user can be immersed in the virtual space. In one embodiment, the virtual space includes, for example, a background, an object that can be operated by the user, and an image of a menu that can be selected by the user. In an embodiment, the monitor 112 may 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 one aspect, the monitor 112 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 112 may be configured to display a right-eye image and a left-eye image together. In this case, the monitor 112 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.

  The HMD sensor 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 120 has a position tracking function for detecting the movement of the HMD 110. Using this function, the HMD sensor 120 detects the position and inclination of the HMD 110 in the real space.

  In another aspect, HMD sensor 120 may be realized by a camera. In this case, the HMD sensor 120 can detect the position and inclination of the HMD 110 by executing image analysis processing using image information of the HMD 110 output from the camera.

  In another aspect, the HMD 110 may include a sensor 114 instead of the HMD sensor 120 as a position detector. The HMD 110 can detect the position and inclination of the HMD 110 itself using the sensor 114. For example, when the sensor 114 is an angular velocity sensor, a geomagnetic sensor, an acceleration sensor, a gyro sensor, or the like, the HMD 110 detects its own position and inclination using any one of these sensors instead of the HMD sensor 120. Can do. As an example, when the sensor 114 is an angular velocity sensor, the angular velocity sensor detects angular velocities around the three axes of the HMD 110 in real space over time. The HMD 110 calculates a temporal change in the angle around the three axes of the HMD 110 based on each angular velocity, and further calculates an inclination of the HMD 110 based on the temporal change in the angle. The HMD 110 may include a transmissive display device. In this case, the transmissive display device may be temporarily configured as a non-transmissive display device by adjusting the transmittance. Further, the visual field image may include a configuration for presenting the real space in a part of the image configuring the virtual space. For example, an image captured by a camera mounted on the HMD 110 may be displayed so as to be superimposed on a part of the field-of-view image, or by setting the transmittance of a part of the transmissive display device to be high. Real space may be visible from a part.

  The gaze sensor 140 detects a direction (gaze direction) in which the gaze of the right eye and the left eye of the user 190 is directed. The detection of the direction 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 the left eye of the user 190 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 direction of the user 190 based on each detected rotation angle.

  The server 150 can send a program to the terminal 200. In another aspect, the server 150 may communicate with other terminals 200 for providing virtual reality to HMDs used by other users. For example, when a plurality of users play a participatory game in an amusement facility, each terminal 200 communicates a signal based on each user's operation with another computer, and a plurality of users share a common game in the same virtual space. Allowing you to enjoy.

  The controller 160 receives an instruction input from the user 190 to the terminal 200. In one aspect, the controller 160 is configured to be gripped by the user 190. In another aspect, the controller 160 is configured to be attachable to the body of the user 190 or a part of clothing. In another aspect, the controller 160 may be configured to output at least one of vibration, sound, and light based on a signal sent from the terminal 200. In another aspect, the controller 160 accepts an operation given by the user 190 to control the position and movement of an object arranged in a space that provides virtual reality.

  In one aspect, the motion sensor 130 is attached to the user's hand and detects the movement of the user's hand. For example, the motion sensor 130 detects the rotation speed, rotation speed, etc. of the hand. The detected signal is sent to terminal 200. The motion sensor 130 is provided in a glove-type controller 160, for example. In some embodiments, for safety in real space, it is desirable that the controller 160 be mounted on something that does not fly easily by being mounted on the hand of the user 190, such as a glove shape. In another aspect, a sensor that is not worn by the user 190 may detect the hand movement of the user 190. For example, a signal from a camera that captures the user 190 may be input to the terminal 200 as a signal representing the operation of the user 190. The motion sensor 130 and the terminal 200 are connected to each other by wire or 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.

[Hardware configuration]
With reference to FIG. 2, terminal 200 according to the present embodiment will be described. FIG. 2 is a block diagram illustrating an example of a hardware configuration of terminal 200 according to one aspect. The terminal 200 includes a processor 10, a memory 11, a storage 12, an input / output interface 13, a communication interface 14, and a monitor 16 as main components. Each component is connected to the bus 15.

  The processor 10 executes a series of instructions included in the program stored in the memory 11 or the storage 12 based on a signal given to the terminal 200 or when a predetermined condition is established. In one aspect, the processor 10 is realized as a CPU (Central Processing Unit), an MPU (Micro Processor Unit), an FPGA (Field-Programmable Gate Array), or other device.

  The memory 11 temporarily stores programs and data. The program is loaded from the storage 12, for example. The data includes data input to the terminal 200 and data generated by the processor 10. In one aspect, the memory 11 is realized as a RAM (Random Access Memory) or other volatile memory.

  The storage 12 holds programs and data permanently. The storage 12 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 12 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 terminal 200. The data stored in the storage 12 includes data and objects for defining the virtual space.

  In another aspect, the storage 12 may be realized as a removable storage device such as a memory card. In still another aspect, instead of the storage 12 built in the terminal 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.

  In some embodiments, the input / output interface 13 communicates signals with the HMD 110, HMD sensor 120, or motion sensor 130. In one aspect, the input / output interface 13 is realized using a USB (Universal Serial Bus) interface, a DVI (Digital Visual Interface), an HDMI (registered trademark) (High-Definition Multimedia Interface), or other terminals. The input / output interface 13 is not limited to that described above.

  In certain embodiments, the input / output interface 13 may further communicate with the controller 160. For example, the input / output interface 13 receives a signal output from the motion sensor 130. In another aspect, the input / output interface 13 sends the instruction output from the processor 10 to the controller 160. The command instructs the controller 160 to vibrate, output sound, emit light, and the like. When the controller 160 receives the command, the controller 160 executes vibration, sound output, or light emission according to the command.

  The communication interface 14 is connected to the network 19 and communicates with other computers (for example, the server 150) connected to the network 19. In one aspect, the communication interface 14 is realized as, for example, a local area network (LAN) or other wired communication interface, or a wireless communication interface such as WiFi (Wireless Fidelity), Bluetooth (registered trademark), NFC (Near Field Communication), or the like. Is done. The communication interface 14 is not limited to the above.

  The monitor 16 can include, for example, a liquid crystal monitor and an organic EL monitor. In another aspect, the monitor 16 may be an external monitor that can be connected to the terminal 200.

  In one aspect, the processor 10 accesses the storage 12, loads one or more programs stored in the storage 12 into the memory 11, and executes a series of instructions included in the program. The one or more programs may include an operating system of the terminal 200, an application program for providing a virtual space, game software that can be executed in the virtual space using the controller 160, and the like. The processor 10 sends a signal for providing a virtual space to the HMD 110 via the input / output interface 13. The HMD 110 displays an image on the monitor 112 based on the signal.

  In the example illustrated in FIG. 2, the terminal 200 is configured to be provided outside the HMD 110. However, in another aspect, the terminal 200 may be incorporated in the HMD 110. As an example, a portable information communication terminal (for example, a smartphone) including the monitor 112 may function as the terminal 200.

  Further, the terminal 200 may be configured to be used in common for a plurality of HMDs 110. 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 global coordinate system is set in advance. The global 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. In the present embodiment, the global coordinate system is one of the viewpoint coordinate systems. Therefore, the horizontal direction, the vertical direction (vertical direction), and the front-rear direction in the global coordinate system are defined as an x-axis, a y-axis, and a z-axis, respectively. More specifically, in the global 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 120 includes an infrared sensor. When the infrared sensor detects the infrared rays emitted from each light source of the HMD 110, the presence of the HMD 110 is detected. The HMD sensor 120 further detects the position and inclination of the HMD 110 in the real space according to the movement of the user 190 wearing the HMD 110 based on the value of each point (each coordinate value in the global coordinate system). More specifically, the HMD sensor 120 can detect temporal changes in the position and inclination of the HMD 110 using each value detected over time.

  The global coordinate system is parallel to the real space coordinate system. Therefore, each inclination of the HMD 110 detected by the HMD sensor 120 corresponds to each inclination around the three axes of the HMD 110 in the global coordinate system. The HMD sensor 120 sets the uvw visual field coordinate system to the HMD 110 based on the inclination of the HMD 110 in the global coordinate system. The uvw visual field coordinate system set in the HMD 110 corresponds to a viewpoint coordinate system when the user 190 wearing the HMD 110 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 a uvw visual field coordinate system set in HMD 110 according to an embodiment. The HMD sensor 120 detects the position and inclination of the HMD 110 in the global coordinate system when the HMD 110 is activated. The processor 10 sets the uvw visual field coordinate system to the HMD 110 based on the detected value.

  As shown in FIG. 3, the HMD 110 sets a three-dimensional uvw visual field coordinate system with the head (origin) of the user wearing the HMD 110 as the center (origin). More specifically, the HMD 110 includes a horizontal direction, a vertical direction, and a front-rear direction (x-axis, y-axis, z-axis) that define the global coordinate system by an inclination around each axis of the HMD 110 in the global coordinate system. Three directions newly obtained by tilting around the axis are set as the pitch direction (u-axis), yaw direction (v-axis), and roll direction (w-axis) of the uvw visual field coordinate system in the HMD 110.

  In a certain situation, when the user 190 wearing the HMD 110 stands upright and is viewing the front, the processor 10 sets the uvw visual field coordinate system parallel to the global coordinate system to the HMD 110. In this case, the horizontal direction (x-axis), vertical direction (y-axis), and front-back direction (z-axis) in the global coordinate system are the pitch direction (u-axis) and yaw direction (v-axis) of the uvw visual field coordinate system in the HMD 110. , And the roll direction (w axis).

  After the uvw visual field coordinate system is set to the HMD 110, the HMD sensor 120 can detect the inclination (the amount of change in inclination) of the HMD 110 in the set uvw visual field coordinate system based on the movement of the HMD 110. In this case, the HMD sensor 120 detects the pitch angle (θu), yaw angle (θv), and roll angle (θw) of the HMD 110 in the uvw visual field coordinate system as the inclination of the HMD 110. The pitch angle (θu) represents the inclination angle of the HMD 110 around the pitch direction in the uvw visual field coordinate system. The yaw angle (θv) represents the inclination angle of the HMD 110 around the yaw direction in the uvw visual field coordinate system. The roll angle (θw) represents the inclination angle of the HMD 110 around the roll direction in the uvw visual field coordinate system.

  The HMD sensor 120 sets the uvw visual field coordinate system in the HMD 110 after the HMD 110 has moved to the HMD 110 based on the detected tilt angle of the HMD 110. The relationship between the HMD 110 and the uvw visual field coordinate system of the HMD 110 is always constant regardless of the position and inclination of the HMD 110. When the position and inclination of the HMD 110 change, the position and inclination of the uvw visual field coordinate system of the HMD 110 in the global coordinate system change in conjunction with the change of the position and inclination.

  In one aspect, the HMD sensor 120 is 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). The position in the real space may be specified as a relative position to the HMD sensor 120. Further, the processor 10 may determine the origin of the uvw visual field coordinate system of the HMD 110 in the real space (global 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 2 according to an embodiment. The virtual space 2 has a spherical structure that covers the entire 360 ° direction of the center 21. In FIG. 4, the upper half of the celestial sphere in the virtual space 2 is illustrated in order not to complicate the description. In the virtual space 2, each mesh is defined. The position of each mesh is defined in advance as coordinate values in the XYZ coordinate system defined in the virtual space 2. The terminal 200 associates each partial image constituting the content (still image, moving image, etc.) that can be developed in the virtual space 2 with each corresponding mesh in the virtual space 2, and the virtual space image 22 that can be visually recognized by the user. Is provided to the user.

  In one aspect, the virtual space 2 defines an XYZ coordinate system with the center 21 as the origin. The XYZ coordinate system is, for example, parallel to the global coordinate system. Since the XYZ coordinate system is a kind of viewpoint coordinate system, the horizontal direction, vertical direction (vertical direction), and front-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 global coordinate system, the Y axis (vertical direction) of the XYZ coordinate system is parallel to the y axis of the global coordinate system, and The Z axis (front-rear direction) is parallel to the z axis of the global coordinate system.

  When the HMD 110 is activated, that is, in the initial state of the HMD 110, the virtual camera 1 is disposed at the center 21 of the virtual space 2. The virtual camera 1 similarly moves in the virtual space 2 in conjunction with the movement of the HMD 110 in the real space. Thereby, changes in the position and orientation of the HMD 110 in the real space are similarly reproduced in the virtual space 2.

  As with the HMD 110, the uvw visual field coordinate system is defined for the virtual camera 1. The uvw visual field coordinate system of the virtual camera in the virtual space 2 is defined so as to be linked to the uvw visual field coordinate system of the HMD 110 in the real space (global coordinate system). Therefore, when the inclination of the HMD 110 changes, the inclination of the virtual camera 1 also changes accordingly. The virtual camera 1 can also move in the virtual space 2 in conjunction with the movement of the user wearing the HMD 110 in the real space.

  Since the orientation of the virtual camera 1 is determined according to the position and inclination of the virtual camera 1, the reference line of sight (reference line of sight 5) when the user visually recognizes the virtual space image 22 depends on the orientation of the virtual camera 1. Determined. The processor 10 of the terminal 200 defines the view area 23 in the virtual space 2 based on the reference line of sight 5. The visual field area 23 corresponds to the visual field of the user wearing the HMD 110 in the virtual space 2.

  The gaze direction of the user 190 detected by the gaze sensor 140 is a direction in the viewpoint coordinate system when the user 190 visually recognizes the object. The uvw visual field coordinate system of the HMD 110 is equal to the viewpoint coordinate system when the user 190 visually recognizes the monitor 112. Further, the uvw visual field coordinate system of the virtual camera 1 is linked to the uvw visual field coordinate system of the HMD 110. Therefore, the HMD system 100 according to a certain aspect can regard the line-of-sight direction of the user 190 detected by the gaze sensor 140 as the line-of-sight direction of the user in the uvw visual field coordinate system of the virtual camera 1.

[User's line of sight]
With reference to FIG. 5, determination of the user's line-of-sight direction will be described. FIG. 5 is a diagram showing the head of user 190 wearing HMD 110 according to an embodiment from above.

  In one aspect, gaze sensor 140 detects each line of sight of user 190's right eye and left eye. In a certain aspect, when the user 190 is looking near, the gaze sensor 140 detects the lines of sight R1 and L1. In another aspect, when the user 190 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 direction w is smaller than the angle formed by the lines of sight R1 and L1 with respect to the roll direction w. The gaze sensor 140 transmits the detection result to the terminal 200.

  When the terminal 200 receives the detection values of the lines of sight R1 and L1 from the gaze sensor 140 as the detection result of the line of sight, the terminal 200 specifies the gazing point 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 terminal 200 identifies the intersection of the lines of sight R2 and L2 as the point of sight. The terminal 200 specifies the line-of-sight direction N0 of the user 190 based on the specified position of the gazing point N1. For example, the terminal 200 detects, as the line-of-sight direction 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 190 and the gazing point N1. The line-of-sight direction N0 is a direction in which the user 190 is actually pointing the line of sight with both eyes. The line-of-sight direction N0 corresponds to the direction in which the user 190 actually directs his / her line of sight with respect to the field-of-view area 23.

  In another aspect, the HMD system 100 may include a microphone and a speaker in any part constituting the HMD system 100. The user can give a voice instruction to the virtual space 2 by speaking to the microphone.

  In another aspect, 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 2.

  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]
With reference to FIGS. 6 and 7, the visual field region 23 will be described. FIG. 6 is a diagram illustrating a YZ cross section of the visual field region 23 viewed from the X direction in the virtual space 2. FIG. 7 is a diagram illustrating an XZ cross section of the visual field region 23 viewed from the Y direction in the virtual space 2.

  As shown in FIG. 6, the visual field region 23 in the YZ cross section includes a region 24. The region 24 is defined by the reference line of sight 5 of the virtual camera 1 and the YZ cross section of the virtual space 2. The processor 10 defines a range including the polar angle α around the reference line of sight 5 in the virtual space as the region 24.

  As shown in FIG. 7, the visual field region 23 in the XZ cross section includes a region 25. The region 25 is defined by the reference line of sight 5 and the XZ cross section of the virtual space 2. The processor 10 defines a range including the azimuth angle β around the reference line of sight 5 in the virtual space 2 as a region 25.

  In one aspect, the HMD system 100 provides the virtual space to the user 190 by displaying the view field image 26 on the monitor 112 based on a signal from the terminal 200. The view image 26 corresponds to a portion of the virtual space image 22 that is superimposed on the view region 23. When the user 190 moves the HMD 110 worn on the head, the virtual camera 1 also moves in conjunction with the movement. As a result, the position of the visual field area 23 in the virtual space 2 changes. As a result, the view image 26 displayed on the monitor 112 is updated to an image that is superimposed on the view region 23 in the direction in which the user faces in the virtual space 2 in the virtual space image 22. The user can visually recognize a desired direction in the virtual space 2.

  While wearing the HMD 110, the user 190 can view only the virtual space image 22 developed in the virtual space 2 without visually recognizing the real world. Therefore, the HMD system 100 can give the user a high sense of immersion in the virtual space 2.

  In one aspect, the processor 10 can move the virtual camera 1 in the virtual space 2 in conjunction with the movement of the user 190 wearing the HMD 110 in the real space. In this case, the processor 10 specifies an image region (that is, a view field region 23 in the virtual space 2) projected on the monitor 112 of the HMD 110 based on the position and orientation of the virtual camera 1 in the virtual space 2.

  According to an embodiment, the virtual camera 1 preferably includes two virtual cameras, that is, a virtual camera for providing an image for the right eye and a virtual camera for providing an image for the left eye. Moreover, it is preferable that appropriate parallax is set in the two virtual cameras so that the user 190 can recognize the three-dimensional virtual space 2. In the present embodiment, the virtual camera 1 includes two virtual cameras, and the roll direction (w) generated by combining the roll directions of the two virtual cameras is adapted to the roll direction (w) of the HMD 110. The technical idea concerning this indication is illustrated as what is constituted.

  The frame 31 includes a plurality of infrared LEDs 35 arranged along the circumferential direction. The infrared LED 35 emits infrared light in accordance with the progress of the program during the execution of the program using the controller 160. The infrared rays emitted from the infrared LED 35 can be used to detect the positions and postures (tilt and orientation) of the right controller 800 and the left controller (not shown). In the example shown in FIG. 8, infrared LEDs 35 arranged in two rows are shown, but the number of arrays is not limited to that shown in FIG. An array of one or more columns may be used.

  The top surface 32 includes buttons 36 and 37 and an analog stick 38. The buttons 36 and 37 are configured as push buttons.

  In an embodiment, the display control module 220 and the virtual space control module 230 are realized by the processor 10. In another embodiment, multiple processors 10 may operate as the display control module 220 and the virtual space control module 230. The memory module 240 is realized by the memory 11 or the storage 12. The communication control module 250 is realized by the communication interface 14.

  In one aspect, the display control module 220 controls image display on the monitor 112 of the HMD 110. The virtual camera control module 221 arranges the virtual camera 1 in the virtual space 2 and controls the behavior, orientation, and the like of the virtual camera 1. The view area determination module 222 defines the view area 23 according to the direction of the head of the user wearing the HMD 110. The view image generation module 223 generates a view image 26 to be displayed on the monitor 112 based on the determined view area 23.

  The reference line-of-sight identifying module 224 identifies the line of sight of the user 190 based on the signal from the gaze sensor 140.

  The virtual space control module 230 controls the virtual space 2 provided to the user 190. The virtual space definition module 231 defines the virtual space 2 in the HMD system 100 by generating virtual space data representing the virtual space 2.

  The virtual object generation module 232 generates an object placed in the virtual space 2. In one aspect, the virtual object generation module 232 generates, for example, a virtual user object corresponding to the user 190 in addition to the 360-degree moving image content.

  The overlay instruction detection module 233 detects an instruction to overlay a mask image on the image data received from the server 150. For example, in an aspect, the overlay instruction detection module 233 detects the instruction from a signal received from the server 150. In another aspect, the overlay instruction detection module 233 detects the instruction based on an operation given to the controller 133 or based on an operation on a keyboard or a touch panel (not shown) included in the terminal 200.

  The mask overlay module 234 generates image data in which the mask image is superimposed on the image data received from the server 150 based on the detection of the instruction by the overlay instruction detection module 233. The mask image is stored in advance in terminal 200 in a certain aspect. In another aspect, the mask image may be received from the server 150 with the image data or separately from the image data. The image data on which the mask image is superimposed is output to the monitor 112 as a demo image. In yet another aspect, the mask image may be incorporated as part of image data distributed from the server 150.

  The memory module 240 holds data used for the terminal 200 to provide the virtual space 2 to the user 190. In one aspect, the memory module 240 holds content data 241, mask image data 242, and user information 243.

  The content data 241 includes image data. The image data includes, for example, image data for three-dimensional display in addition to two-dimensional images, image data that can be displayed 360 degrees (including data for defining a virtual space and providing virtual reality to the user). Including. The two-dimensional image includes an image stored as a two-dimensional image by, for example, capturing an image displayed on a display such as the HMD 110 in a system that originally provides virtual reality. These image data are received from the server 150, for example.

  Mask image data 242 represents a mask imitating the contour of HMD 110. Mask image data 242 is superimposed on an image based on image data for three-dimensional display or image data that can be displayed 360 degrees. When the monitor 112 displays an image with a mask, the user 190 displays two-dimensional content for viewing the image using the HMD 110 (for example, an image provided in virtual reality). Can be recognized as a demo image).

  The user information 243 includes identification information of the user 190 of the HMD 110, authority associated with the user 190, and the like.

  The communication control module 250 can communicate with the server 150 and other information communication devices via the network 19.

  In an aspect, the display control module 220 and the virtual space control module 230 may be realized using, for example, Unity (registered trademark) provided by Unity Technologies. In another aspect, the display control module 220 and the virtual space control module 230 can also be realized as a combination of circuit elements that realize each process.

  The processing in the terminal 200 is realized by hardware and software executed by the processor 10. Such software may be stored in advance in a memory module 240 such as a hard disk. The software may be stored in a CD-ROM or other non-volatile computer-readable data recording medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to the Internet or other networks. Such software is read from a data recording medium by an optical disk drive or other data reader, or downloaded from the server 150 or other computer via the communication control module 250 and then temporarily stored in the storage module. . The software is read from the storage module by the processor 10 and stored in the RAM in the form of an executable program. The processor 10 executes the program.

  The hardware that constitutes the terminal 200 is general. Therefore, it can be said that the most essential part according to the present embodiment is a program stored in terminal 200. Since the hardware operation of terminal 200 is well known, detailed description will not be repeated.

  The data recording medium is not limited to a CD-ROM, FD (Flexible Disk), and hard disk, but is a magnetic tape, cassette tape, optical disk (MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital Versatile Disc)). ), IC (Integrated Circuit) card (including memory card), optical card, mask ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), flash ROM, etc. It may be a non-volatile data recording medium that carries a fixed program.

  The program here may include not only a program directly executable by the processor 10, but also a program in a source program format, a compressed program, an encrypted program, and the like.

  The control structure of the HMD system will be described with reference to FIG. FIG. 10 is a flowchart representing a part of processing executed by terminal 200 and server 150 according to an embodiment. The example shown in FIG. 10 represents processing when an instruction to add a mask image is detected by terminal 200 and a mask image is added at terminal 200 based on the instruction.

  In step S1010, processor 10 of terminal 200 transmits a content distribution request to server 150 based on the fact that user 190 has selected the content. The distribution request is sent to the server 150 via the network 19.

  In step S1020, server 150 receives the distribution request transmitted from terminal 200 via communication interface 153. The processor 151 of the server 150 reads content data specified by the distribution request from the memory 152 or an external storage device. In one aspect, the content is originally content data generated as a two-dimensional image by capturing an image based on data for providing virtual reality (including data defining a virtual space), or 360-degree video Information indicating that is included in the management information of the content. This information is used as an instruction for mask overlay when the HMD 110 is not used. The processor 151 associates the identification information of the user 190 with the identification information of the content requested to be distributed, and stores it in the memory 152.

  In step S1030, processor 151 transmits the read content data and management information to terminal 200 via communication interface 153.

  In step S1040, terminal 200 receives content data and management information transmitted from server 150.

  In step S1050, processor 10 of terminal 200 determines whether an instruction to overlay a mask image is detected. In one aspect, this determination is made based on whether or not the instruction is included in the management information received from the server 150. In another aspect, this determination is based on whether the content is content that was originally generated as a two-dimensional image based on data for providing virtual reality or 360-degree video content (the content depends on the head-mounted device). Based on whether or not it relates to viewing). For example, if the data is not originally data for providing virtual reality or 360-degree video content, the content creator keeps in mind that the content is viewed in two dimensions. For this reason, it is not necessary to suggest that the content is originally data that provides virtual reality or 360-degree moving image content, and therefore no additional mask image is required. In yet another aspect, this determination is made based on whether or not the operation given to terminal 200 by user 190 is the instruction. When processor 10 determines that the instruction has been detected (YES in step S1050), control is switched to step S1060. Otherwise (NO in step S1050), processor 10 switches control to step S1070.

  In step S1060, processor 10 generates data in which the mask image is overlaid on the content. In one aspect, data for displaying a mask image is stored in the terminal 200 as data received in advance from a service that distributes the content, for example. In another aspect, data for displaying a mask image may be included in data received from server 150.

  In step S1070, processor 10 outputs the received content data to monitor 16. When the user 190 is not wearing the HMD 110 in which the terminal 200 is incorporated, the monitor 16 displays the content in a normal manner (without adding a mask image) based on the data. In another aspect, if the user 190 is wearing the HMD 110 in which the terminal 200 is incorporated, or if the user 190 is wearing the HMD 110 in which a monitor is incorporated, the user can enjoy virtual reality content or a 360-degree video. be able to.

  In step S1080, processor 10 outputs the generated data to monitor 16. The monitor 16 displays the content with the mask image added. Even if the user 190 who views the content visually recognizes the mask image without using the HMD 110, the user 190 can easily understand that the content is content presented in the virtual space 2 using the HMD 110.

[The server detects an instruction to add a mask image]
The control structure of the HMD system will be described with reference to FIG. FIG. 11 is a flowchart representing a part of processing executed by terminal 200 and server 150 according to an embodiment. The example shown in FIG. 11 represents a case where an instruction to add a mask image is given from server 150 to terminal 200 and a mask image is added at terminal 200 based on the instruction. Note that the same step numbers are assigned to the same processes as those described above. Therefore, the description of the same process will not be repeated.

  In step S1110, processor 151 of server 150 determines whether or not the content requested by terminal 200 is assumed to be a viewing mode other than two-dimensional display by the content creator. That is, the processor 151 of the server 150 determines whether the content requested by the terminal 200 is content originally generated as a two-dimensional image or 360-degree moving image content based on data for providing virtual reality. In some embodiments, the content assumed to be a viewing mode other than the two-dimensional display may include, for example, virtual reality content, 360-degree moving image content, and the like. If processor 151 determines that the content is content that is assumed to be a viewing mode other than two-dimensional display (the content is “content other than two-dimensional display”) (YES in step S1110), control is performed in step 1120. Switch to. Otherwise (NO in step S1110), processor 151 switches control to step S1130.

  In step S1120, processor 151 transmits an instruction to synthesize a mask image to terminal 200.

  In step S1130, processor 151 transmits the requested content data to terminal 200. Terminal 200 receives this data (step S1040).

  In step S1140, processor 10 of terminal 200 determines whether the data received from server 150 includes an instruction to synthesize a mask image. When processor 10 determines that the data includes the instruction (YES in step S1140), processor 10 switches control to step S1060. The terminal 200 generates data on which the mask image is overlaid (step S1060), and outputs the data to the monitor 16 (step S1080). By visually recognizing the image output to the monitor 16, the user 190 can recognize that the content is originally a virtual reality content two-dimensionally displayed or a 360-degree moving image. Otherwise (NO in step S1140), processor 10 switches control to step S1070. The terminal 200 displays an image with no mask image added on the monitor 16 (step S1070). The user 190 can visually recognize the content for two-dimensional display in a normal manner.

[Server adds mask image]
The control structure of the HMD system 100 will be further described with reference to FIG. FIG. 12 is a flowchart representing a part of processing executed by terminal 200 and server 150 according to an embodiment. The example shown in FIG. 12 represents a case where the mask image is overlaid by the server 150. Note that the same step numbers are assigned to the same processes as those described above. Therefore, the description of the same process will not be repeated.

  In step S1210, processor 151 of server 150 receives a content distribution request and attribute information from terminal 200. In one aspect, the attribute information includes information indicating that the terminal 200 is not attached to the HMD 110, information indicating that the terminal 200 is the HMD 110, information indicating that the terminal 200 is attached to the HMD 110, and the like. Including.

  In step S1220, processor 151 determines whether terminal 200 is HMD 110 or not. This determination is made based on attribute information, for example. If processor 151 determines that terminal 200 is HMD 110 or is attached to HMD 110 (YES in step S1220), control proceeds to step S1230. Otherwise, control is transferred to step S1110.

  In step S1230, processor 151 reads the content requested for distribution from memory 152 or an external storage device, and transmits the content to terminal 200 without adding an image for masking. When the terminal 200 receives this content (step S1040), an image is output to the HMD 110 (step S1070). A user 190 wearing the HMD 110 can enjoy a 360-degree moving image and the like. When the data transmitted from the terminal 200 is data of two-dimensional content, the user 190 can view the two-dimensional content with the HMD 110 attached.

  In step S1240, processor 151 generates content on which the mask image is overlaid. At this time, the processor 151 adjusts the mask image according to the specification of the HMD 110. The processor 151 transmits the generated data to the terminal 200.

  In step S1040, terminal 200 receives, from server 150, data without a mask image (step S1230) or content data with a mask image added (step S1240).

  In step S1140, processor 10 of terminal 200 determines whether the data received from server 150 includes an instruction to synthesize a mask image. When processor 10 determines that the data includes the instruction (YES in step S1140), processor 10 switches control to step S1060. The processor 10 generates data in which the mask image is overlaid on the content (step S1060), and outputs the generated data to the monitor 16 (step S1080). When the user 190 looks at the screen with the mask image attached, the user 190 can easily recognize that the screen is a demonstration screen for virtual reality or 360-degree moving image content. Otherwise (NO in step S1140), processor 10 switches control to step S1270. The instruction to synthesize the mask image may be specified when the content creator uploads the content to the server 150. That is, the content creator informs the user that the moving image to be uploaded to the server 150 is originally captured data for providing virtual reality into moving image data, etc., by an instruction to synthesize the mask image. Can be easily notified.

  In step S1270, processor 10 outputs the received data to monitor 16 or HMD 110. For example, when virtual reality content data or 360 moving image content data is received when the terminal 200 is attached to the HMD 110, the processor 10 outputs the data received from the server 150 to the HMD 110. The user 190 can enjoy the content presented in the virtual space 2 through the HMD 110. On the other hand, when the terminal 200 is not attached to the HMD 110, when the terminal 200 receives content data for two-dimensional display (data that does not capture data for providing virtual reality as two-dimensional data), the terminal 200 The data received from the server is output to the monitor 16. The monitor 16 displays the content for two-dimensional display in a normal manner.

  The display mode of the screen will be described with reference to FIG. FIG. 13 is a diagram showing the transition of the screen displayed on monitor 16 according to an embodiment. At this time, the terminal 200 is not attached to the HMD 110.

  As shown in the screen (A), when the user 190 operates the terminal 200 to access a service site that distributes content, the monitor 16 displays a screen that prompts the user to select content. The terminal 200 transmits data for identifying the content selected by the user 190 and a distribution request for the content to the server 150. The server 150 transmits content data to the terminal 200 in response to the request.

  As shown in the screen (B), the monitor 16 displays that the content is originally a virtual reality content or 360-degree moving image content, and issues a message inquiring whether or not the mask image should be used. indicate.

  As shown in the screen (C), when the user 190 selects “Yes” in response to the above inquiry, the terminal 200 generates data in which the mask image is added to the content. The monitor 16 displays a mask image 1300 and a content image 1310 based on the data. Since the mask image 1300 is reminiscent of the outline of the goggles of the HMD 110, when the user 190 visually recognizes the mask image 1300, the content image 1310 is originally a content for virtual reality or 360 video content. Can be easily recognized.

  As shown in the screen (D), in another aspect, the monitor 16 may indicate that the content with the mask image is displayed without waiting for an instruction from the user 190.

  In another aspect, terminal 200 may display the content to which the mask image is added without displaying a message such as screen (B) or screen (D) (screen (C)).

  Thereafter, when the user 190 attaches the terminal 200 to the HMD 110 or displays the content on a device capable of viewing virtual reality content or 360-degree video content, as shown in the screen (E). The mask image 1300 is not displayed and the image 1310 of the content is presented in the virtual space 2.
