[HMD system configuration]
The configuration of the HMD system 100 will be described with reference to FIG. FIG. 1 is a diagram illustrating an outline of a configuration of an HMD system 100 according to an embodiment. In certain aspects, the HMD system 100 is provided as a home system or a business system.

The HMD system 100 includes an HMD 110, an HMD sensor 120, a controller 160, and a computer 200. The HMD 110 includes a monitor 112, a gaze sensor 140, a speaker 115, and a microphone 119. The controller 160 may include a motion sensor 130.

In one aspect, the computer 200 can connect to the Internet or other network 19 and can communicate with the server 150 or other computer connected to the network 19. In another aspect, the HMD 110 may include the sensor 114 instead of the HMD sensor 120.

The HMD 110 may be mounted on the head of the user 190 and provide the virtual space 2 to the user 190 during operation. More specifically, the HMD 110 displays an image for the right eye and an image for the left eye on the monitor 112, respectively. When each eye of the user 190 visually recognizes the respective image, the user 190 can recognize the image as a three-dimensional image based on the parallax of both eyes.

The monitor 112 is realized, for example, as a non-transparent display device. In one aspect, the monitor 112 is arranged in the body of the HMD 110 so as to be located in front of both eyes of the user 190. Therefore, the user 190 can immerse himself / herself in the virtual space 2 when he / she visually recognizes the three-dimensional image displayed on the monitor 112. In certain embodiments, the virtual space 2 includes, for example, a background, an object operable by the user 190, and an image of a menu selectable by the user 190. If the configuration is such that a plurality of computers 200 can experience a virtual experience in one virtual space 2 by passing a signal based on the operation of each user, the avatar object corresponding to each user is presented in the virtual space 2. Will be done.

In another aspect, the monitor 112 may be configured to display the image for the right eye and the image for the left eye as a unit. In this case, the monitor 112 includes a high speed shutter. The high-speed shutter operates so that the image for the right eye and the image for the left eye can be alternately displayed so that the image is recognized by only one of the eyes.

The gaze sensor 140 detects the direction in which the line of sight of the right eye and the left eye of the user 190 is directed (line-of-sight direction). Detection in that direction is achieved, for example, by a known eye tracking function. The gaze sensor 140 is realized by a sensor having the eye tracking function. In certain aspects, the gaze sensor 140 preferably includes a sensor for the right eye and a sensor for the left eye. The gaze sensor 140 may be, for example, a sensor that irradiates the right eye and the left eye of the user 190 with infrared light and detects the angle of rotation of each eyeball by receiving the reflected light from the cornea and the iris with respect to the irradiation light. .. The gaze sensor 140 can detect the line-of-sight direction of the user 190 based on each detected rotation angle.

The microphone 119 outputs voice data corresponding to the utterance of the user 190 to the computer 200. The user 190 can use the microphone 119 to speak to another user, while the speaker 115 can hear the voice (utterance) of the other user.

More specifically, when the user 190 speaks into the microphone 119, the voice data corresponding to the utterance of the user 190 is input to the computer 200. The computer 200 outputs the voice data to the server 150 via the network 19. The server 150 outputs the voice data received from the computer 200 to another computer 200 via the network 19. The other computer 200 outputs the voice data received from the server 150 to the speaker 115 of the HMD 110 worn by another user. As a result, other users can hear the voice of the user 190 through the speaker 115 of the HMD 110. Similarly, utterances from other users are output from the speaker 115 of the HMD 110 worn by the user 190.

The computer 200 displays on the monitor 112 an image that moves another avatar object corresponding to the other user according to the voice data received from the computer 200 of the other user. For example, in a certain situation, the computer 200 displays an image that moves the mouth of another avatar object on the monitor 112, so that the virtual space 2 is displayed as if the avatar objects are talking to each other in the virtual space 2. Express. By transmitting and receiving voice data between the plurality of computers 200 in this way, a conversation (chat) between a plurality of users is realized in one virtual space 2.

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. The HMD sensor 120 uses this function to detect the position and tilt of the HMD 110 in the real space.

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

In another aspect, the HMD 110 may include the sensor 114 as the position detector instead of the HMD sensor 120. The HMD 110 may use the sensor 114 to detect the position and tilt of the HMD 110 itself. For example, if the sensor 114 is an angular velocity sensor, a geomagnetic sensor, an acceleration sensor, or a gyro sensor, the HMD 110 uses any of these sensors instead of the HMD sensor 120 to determine its position and tilt. Can be detected. As an example, when the sensor 114 is an angular velocity sensor, the angular velocity sensor detects the angular velocity around the three axes of the HMD 110 in real space over time. The HMD 110 calculates the temporal change of the angle around the three axes of the HMD 110 based on each angular velocity, and further calculates the inclination of the HMD 110 based on the temporal change of the angle.

Further, the HMD 110 may be provided with a transmissive display device. In this case, the transmissive display device may be temporarily configured as a non-transparent display device by adjusting its transmittance. Further, the visual field image may include a configuration for presenting the real space as a part of the image constituting the virtual space 2. For example, an image taken by a camera mounted on the HMD 110 may be superimposed on a part of the field image and displayed, or by setting a high transmittance of a part of the transmissive display device, the field image may be displayed. The real space may be visible from a part.

The server 150 may send the program to the computer 200. In another aspect, the server 150 may communicate with another computer 200 to provide virtual reality to the HMD 110 used by another user. For example, in an amusement facility, when a plurality of users play a participatory game, each computer 200 communicates a signal based on the operation of each user with another computer 200, and the plurality of users are common in the same virtual space 2. Allows you to enjoy the game. Further, as described above, the plurality of computers 200 transmit and receive signals based on the actions of each user, so that a plurality of users can enjoy a conversation in one virtual space 2.

The controller 160 receives an instruction input from the user 190 to the computer 200. In one aspect, the controller 160 is configured to be grippable by the user 190. In another aspect, the controller 160 is configured to be wearable on a part of the body or clothing of the user 190. In another aspect, the controller 160 may be configured to output at least one of vibration, sound, and light based on the signal sent from the computer 200. In another aspect, the controller 160 accepts operations given by the user 190 to control the position and movement of objects placed in the space providing virtual reality.

The motion sensor 130 is attached to the hand of the user 190 in a certain aspect and detects the movement of the hand of the user 190. For example, the motion sensor 130 detects the rotation speed, the number of rotations, and the like of the hand. Data representing the detection result of the hand movement of the user 190 obtained by the motion sensor 130 (hereinafter, also referred to as detection data) is sent to the computer 200. The motion sensor 130 is provided in, for example, a glove-shaped controller 160. In certain embodiments, for safety in real space, it is desirable that the controller 160 be attached to something that does not easily fly by being attached to the user 190's hand, such as a glove type. In another aspect, a sensor not attached to the user 190 may detect the movement of the user 190's hand. For example, the signal of the camera that captures the user 190 may be input to the computer 200 as a signal representing the operation of the user 190. The motion sensor 130 and the computer 200 are connected to each other by wire or wirelessly. In the case of wireless communication, the communication mode is not particularly limited, and for example, Bluetooth (registered trademark) or other known communication method is used.

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 2.

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

[Computer hardware configuration]
The computer 200 according to the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing an example of the hardware configuration of the computer 200 according to one aspect. The computer 200 includes a processor 10, a memory 11, a storage 12, an input / output interface 13, and a communication interface 14 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 the signal given to the computer 200 or based on the condition that a predetermined condition is satisfied. In a certain 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 storage 12, for example. The data includes data input to the computer 200 and data generated by the processor 10. In a certain aspect, the memory 11 is realized as a RAM (Random Access Memory) or other volatile memory.

Storage 12 permanently retains programs and data. The storage 12 is realized as, for example, a ROM (Read-Only Memory), a hard disk device, a flash memory, or other non-volatile storage device. The program stored in the storage 12 includes a program for providing the virtual space 2 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 12 includes data and objects for defining the virtual space 2.

In another aspect, the storage 12 may be realized as a removable storage device such as a memory card. In still other aspects, configurations may be used that use programs and data stored in an external storage device instead of the storage 12 built into the computer 200. With such a configuration, it becomes possible to collectively update programs and data in a situation where a plurality of HMD systems 100 are used, for example, in an amusement facility.

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

In certain embodiments, the input / output interface 13 may further communicate with the controller 160. For example, the input / output interface 13 receives an input of a signal output from the motion sensor 130. In another aspect, the input / output interface 13 sends an instruction output from the processor 10 to the controller 160. The command instructs the controller 160 to vibrate, output voice, emit light, and the like. Upon receiving the command, the controller 160 executes either vibration, audio output, or light emission in response to the command.

The communication interface 14 is connected to the network 19 and communicates with another computer (for example, a server 150, another user's computer 200, etc.) connected to the network 19. In a certain aspect, the communication interface 14 is realized as, for example, a LAN (Local Area Network) or other wired communication interface, or a WiFi (Wireless Fidelity), Bluetooth (registered trademark), NFC (Near Field Communication) or other wireless communication interface. Will be done. The communication interface 14 is not limited to the above.

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 contained in the program. The one or more programs may include an operating system of the computer 200, an application program for providing the virtual space 2, game software that can be executed in the virtual space 2 using the controller 160, and the like. The processor 10 sends a signal for providing the virtual space 2 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 shown in FIG. 2, the computer 200 is configured to be provided outside the HMD 110, but in other aspects, the computer 200 may be built in the HMD 110. As an example, a portable information communication terminal (for example, a smartphone) including a monitor 112 may function as a computer 200.

Further, the computer 200 may have a configuration commonly used for a plurality of HMD 110s. According to such a configuration, for example, the same virtual space 2 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 2.

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

In one aspect, the HMD sensor 120 includes an infrared sensor. When the infrared sensor detects 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 a temporal change in the position and inclination of the HMD 110 by using each value detected over time.

The global coordinate system is parallel to the coordinate system in real space. Therefore, each inclination of the HMD 110 detected by the HMD sensor 120 corresponds to each inclination of the HMD 110 around three axes in the global coordinate system. The HMD sensor 120 sets the uvw field coordinate system to the HMD 110 based on the tilt of the HMD 110 in the global coordinate system. The uvw field-of-view coordinate system set in the HMD 110 corresponds to the viewpoint coordinate system when the user 190 wearing the HMD 110 sees an object in the virtual space 2.

[Uvw field coordinate system]
The uvw field coordinate system will be described with reference to FIG. FIG. 3 is a diagram conceptually representing the uvw field coordinate system set in the HMD 110 according to an embodiment. The HMD sensor 120 detects the position and tilt of the HMD 110 in the global coordinate system when the HMD 110 is activated. The processor 10 sets the uvw field coordinate system to the HMD 110 based on the detected values.

As shown in FIG. 3, the HMD 110 sets a three-dimensional uvw visual field coordinate system centered (origin) on the head of the user 190 wearing the HMD 110. More specifically, the HMD 110 defines the global coordinate system in the horizontal, vertical, and front-back directions (x-axis, y-axis, z-axis) by the inclination of each axis of the HMD 110 in the global coordinate system. The three directions newly obtained by tilting each about the axis are set as the pitch direction (u axis), the yaw direction (v axis), and the roll direction (w axis) of the uvw field coordinate system in the HMD 110.

In a certain aspect, when the user 190 wearing the HMD 110 is upright and visually recognizing the front, the processor 10 sets the uvw field coordinate system parallel to the global coordinate system to the HMD 110. In this case, the horizontal direction (x-axis), the vertical direction (y-axis), and the anteroposterior direction (z-axis) in the global coordinate system are the pitch direction (u-axis) and the yaw direction (v-axis) of the uvw 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 (change amount of the 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, respectively. The pitch angle (θu) represents the tilt angle of the HMD 110 around the pitch direction in the uvw visual field coordinate system. The yaw angle (θv) represents the tilt angle of the HMD 110 around the yaw direction in the uvw visual field coordinate system. The roll angle (θw) represents the tilt angle of the HMD 110 around the roll direction in the uvw visual field coordinate system.

The HMD sensor 120 sets the uvw field coordinate system in the HMD 110 after the HMD 110 has moved based on the detected tilt angle of the HMD 110 in the HMD 110. The relationship between the HMD 110 and the uvw field coordinate system of the HMD 110 is always constant regardless of the position and tilt 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 obtained based on the output from the infrared sensor and the relative positional relationship between the points (eg, the distance between the points). The position of the above in the real space may be specified as a relative position with respect 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 2 will be further described with reference to FIG. FIG. 4 is a diagram conceptually representing one aspect of expressing the virtual space 2 according to a certain embodiment. The virtual space 2 has an all-sky spherical structure that covers the entire center 21 in the 360-degree direction. In FIG. 4, the celestial sphere in the upper half of the virtual space 2 is illustrated so as not to complicate the explanation. Each mesh is defined in the virtual space 2. The position of each mesh is predetermined as a coordinate value in the XYZ coordinate system defined in the virtual space 2. The computer 200 associates each partial image constituting the contents (still image, moving image, etc.) expandable in the virtual space 2 with each corresponding mesh in the virtual space 2, and the virtual space image visible to the user 190. The virtual space 2 in which 22 is expanded is provided to the user 190.

In a certain 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, the vertical direction (vertical direction), and the front-back direction in the XYZ coordinate system are defined as the X-axis, the Y-axis, and the 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, and the Y-axis (vertical direction) of the XYZ coordinate system is parallel to the y-axis of the global coordinate system. The Z-axis (front-back direction) is parallel to the z-axis of the global coordinate system.

At the time of starting the HMD 110, that is, in the initial state of the HMD 110, the virtual camera 1 is arranged at the center 21 of the virtual space 2. The virtual camera 1 moves in the virtual space 2 in the same manner as the movement of the HMD 110 in the real space. As a result, changes in the position and orientation of the HMD 110 in the real space are similarly reproduced in the virtual space 2.

As in the case of the HMD 110, the virtual camera 1 is defined with the uvw field-of-view coordinate system. The uvw field-of-view coordinate system of the virtual camera in the virtual space 2 is defined to be linked to the uvw field-of-view 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. Further, the virtual camera 1 can also move in the virtual space 2 in conjunction with the movement of the user 190 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 190 visually recognizes the virtual space image 22 depends on the orientation of the virtual camera 1. Is decided. The processor 10 of the computer 200 defines the field of view 23 in the virtual space 2 based on the reference line of sight 5. The field of view 23 corresponds to the field of view of the user 190 wearing the HMD 110 in the virtual space 2.

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

[User's line of sight]
The determination of the line-of-sight direction of the user 190 will be described with reference to FIG. FIG. 5 is a top view of the head of a user 190 wearing an HMD 110 according to an embodiment.

In one aspect, the gaze sensor 140 detects each line of sight of the user 190's right and left eyes. In one 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 computer 200.

When the computer 200 receives the detection values of the lines of sight R1 and L1 from the gaze sensor 140 as the detection result of the line of sight, the computer 200 identifies the gaze point N1 which is the intersection of the lines of sight R1 and L1 based on the detected values. On the other hand, when the computer 200 receives the detected values of the lines of sight R2 and L2 from the gaze sensor 140, the computer 200 identifies the intersection of the lines of sight R2 and L2 as the gaze point. The computer 200 specifies the line-of-sight direction N0 of the user 190 based on the position of the specified gazing point N1. For example, the computer 200 detects the midpoint of the straight line connecting the right eye R and the left eye L of the user 190 and the extending direction of the straight line passing through the gazing point N1 as the line-of-sight direction N0. The line-of-sight direction N0 is the direction in which the user 190 actually directs the line of sight with both eyes. Further, the line-of-sight direction N0 corresponds to the direction in which the user 190 actually directs the line of sight to the field-of-sight area 23.

[Visibility area]
The view area 23 will be described with reference to FIGS. 6 and 7. FIG. 6 is a diagram showing a YZ cross section of the field of view 23 as viewed from the X direction in the virtual space 2. FIG. 7 is a diagram showing an XZ cross section of the field of view 23 as viewed from the Y direction in the virtual space 2.

As shown in FIG. 6, the field of view region 23 in the YZ cross section includes the 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.
