[Overview of system configuration]
FIG. 1 is a block diagram showing a configuration of an image change system 1 according to an embodiment of the present invention. The system 1 includes a position designation unit 2, a timing designation unit 3, a display mode change information output unit 4, and an image output unit 5. Details of the functions performed by the components 2 to 5 of the system 1 will be described in detail below.

[Overview of overall system hardware configuration]
FIG. 2 is a conceptual diagram showing an overview of the hardware configuration of the entire system including an embodiment of the present invention. The hardware configuration of the entire system 100 includes an HMD 120 and an image generation apparatus 200. For example, the HMD 120 and the image generation apparatus 200 are electrically connected by a wired cable 150 and can communicate with each other. Instead of the wired cable 150, a wireless connection may be used.

  The HMD 120 is a display device that is used by being worn on the head of the user 101. The HMD 120 includes a display 122 and a sensor 126. The HMD 120 may further include a speaker (headphone) (not shown).

  The display 122 is configured to present an image to the field of view of the user 101 wearing the HMD 120. For example, the display 122 can be configured as a non-transmissive display. In this case, the external scene of the HMD 120 is blocked from the view of the user 101, and only the image displayed on the display 122 is delivered to the user's 101 eye. For example, an image generated using computer graphics is displayed on the display 122. An example of an image by computer graphics is a virtual reality space image obtained by imaging a virtual reality space, for example, a world created by a computer game.

  The sensor 126 is a sensor for detecting in which direction the head of the user 101 wearing the HMD 120 is facing. As the sensor 126, for example, any one of a magnetic sensor, an angular velocity sensor, an acceleration sensor, or a combination thereof may be used. When the sensor 126 is a magnetic sensor, an angular velocity sensor, or an acceleration sensor, the sensor 126 is built in the HMD 120 and outputs a value (magnetism, angular velocity, or acceleration value) corresponding to the direction or movement of the HMD 120. By processing the output value from the sensor 126 by an appropriate method, the head orientation of the user 101 wearing the HMD 120 is calculated. The orientation of the head of the user 101 can be used to change the display image of the display 122 so as to follow the movement when the user 101 moves the head. For example, when the user 101 turns his head to the right (or left, up, down), the display 122 displays a virtual scene in the right (or left, up, down) direction of the user in the virtual reality space. become.

  Note that a sensor provided outside the HMD 120 may be applied as the sensor 126. For example, the sensor 126 may be an infrared sensor installed at a fixed position in the room that is separate from the HMD 120. By using this infrared sensor to detect an infrared reflective marker provided on the surface of the HMD 120, the orientation of the head of the user 101 wearing the HMD 120 can be specified.

  The image generation apparatus 200 is a system for generating an image displayed on the HMD 120. The image generation apparatus 200 includes at least a processor 202, a memory 204, a user input interface 206, and a communication interface 208 as hardware configurations. The image generation apparatus 200 may be a dedicated apparatus, but can be realized as, for example, a personal computer, a game console, a smartphone, a PDA (Personal Digital Assistant), a tablet terminal, or the like.

  The memory 204 stores at least an operating system and an image generation program. The operating system is a computer program for controlling the overall operation of the image generation apparatus 200. The memory 204 can also store data generated by the operation of the image generating apparatus 200 temporarily or permanently. Specific examples of the memory 204 include a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, a flash memory, and an optical disk.

  The processor 202 is configured to read a program stored in the memory 204 and execute processing according to the program. Screen generation is performed by the processor 202 executing a program stored in the memory 204. The processor 202 includes a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit).

  The user input interface 206 is configured to receive an input for operating the image generating apparatus 200 from a user of the image display system 100. Specific examples of the user input interface 206 are a game controller, a touch pad, a mouse, a keyboard, and the like.

  The communication interface 208 is a network interface for communicating with other devices via a network.

  The image generation program may be constructed as a program independent of the SNS platform, or may be a program provided on the SNS platform. When the program is a program provided on the SNS platform, the program (application software) is mounted on a server, and the server performs arithmetic processing and data for image generation in accordance with each user's input operation. Processing will be executed. Therefore, in such a case, it is not necessary to store the image generation program in the memory 204.

[Basic operation of image generation device]
Next, the basic operation of the image generation apparatus 200 will be described. In the following description, the virtual space is a virtual reality (VR) space. However, it should be noted that the virtual space is merely an example and the virtual space is not limited to the VR space.

  FIG. 3 is a block diagram showing the configuration of the basic functions of the image generation apparatus 200. Image generation processing realized by the processor 202 shown in FIG. 2 reading and executing the image generation program in the memory 204 is shown. Represents a function.

  The image generation unit 231 generates an image to be displayed on the HMD 120. For example, the image generation unit 231 acquires predetermined data from the storage unit 220 and generates an image by computer graphics processing based on the acquired data. As an example, the image generation unit 231 generates a virtual reality space image that allows the second user 101 wearing the HMD 120 to recognize a virtual reality space based on a computer game. The virtual reality space image represents a scene that the user can see in the virtual reality space. For example, the virtual reality space image generated by the image generation unit 231 includes characters appearing in a computer game, landscapes such as buildings and trees, interior furniture and wall interiors, items falling on the ground, and user operations. It includes various objects such as a body part (hand or foot) of an avatar (self) and an object (gun or sword) held by the avatar. Data necessary for generating a virtual reality space image, such as the arrangement position, shape, and color of each object constituting the virtual reality space, is stored in the storage unit 220 as virtual reality space configuration information 221. The image generation unit 231b generates a virtual reality space image of such a computer game based on the virtual reality space configuration information 221 acquired from the storage unit 220.

  The image generation unit 231 changes the image based on the output value from the sensor 126. For example, the image generated by the image generation unit 231 is an image representing a state in which the user's field of view in the virtual reality space changes following the movement of the head of the user 101 indicated by the output value from the sensor 126. Good. As an example, FIG. 4 schematically illustrates the movement of the user's head. As shown in the figure, the axis connecting the center of the head of the user 101 and the center of the HMD 120 (the center of the screen of the display 122) is the Z axis, the axis connecting the center of the head of the user 101 and the top is the Y axis, and the user 101 An axis that passes through the center of the head and is orthogonal to the Y axis and the Z axis is taken as the X axis. When the sensor 126 is, for example, an angular velocity sensor, the sensor 126 outputs angular velocity values of the pitch angle around the X axis, the yaw angle around the Y axis, and the roll angle around the Z axis. The image generation unit 231 changes the virtual reality space image based on the output values of these angular velocities, that is, the head direction of the user 101. For example, when the user 101 turns his head to the right, the yaw angle around the Y axis changes. The image generation unit 231 changes the virtual reality space image so that a scene in the right direction of the user is projected in the virtual reality space in accordance with the change in the angular velocity value of the Y axis. Similarly, when the user 101 tilts his / her head to the right, the roll angle around the Z axis changes. The image generation unit 231 changes the virtual reality space image so that the user's field of view in the virtual reality space is tilted to the right in accordance with the change in the angular velocity value of the Z axis.

  The image generation unit 231 changes the image based on the position of the user. For example, when the user walks around in the virtual reality space, the image generated by the image generation unit 231 may be an image representing a sight seen from a position where the user is currently standing in the virtual reality space. As an example, the user's temporal position information in the virtual reality space is stored in the storage unit 220. The image generation unit 231 acquires position information immediately before the user in the virtual reality space from the storage unit 220. Also, from the user input interface 206 such as a game controller, an instruction of the user's moving direction and moving speed is input as an operation input for the user to walk around in the virtual reality space. Based on the position information immediately before the user acquired from the storage unit 220 and the information on the moving direction and moving speed of the user input from the user input interface 206, the image generating unit 231 displays the current user's position in the virtual reality space. Calculate the position. Based on the calculated current position of the user, the image generation unit 231 changes the virtual reality space image so that the user's field of view changes as the user walks in the virtual reality space.

  In this way, the image generation unit 231 generates a virtual reality space image corresponding to the user's position and head orientation in the virtual reality space. The generated virtual reality space image is output to the HMD 120 via the image output unit 239 and displayed on the display 122. As a result, the user can see a virtual scene in the virtual reality space that is present in the direction of the head from the place where the user is currently standing.

As apparent from the comparison between the two figures, the display mode of the broken line region 502 representing the vicinity of the designated position 501 in the virtual reality space as shown in FIG. Is changed to a region 502 ′. As described above, the image change system has a function of appropriately changing an object and / or an action in the vicinity of a specified position in the virtual reality space at a specified timing and changing a display mode in the vicinity of the position.
