<Embodiment>
[Overall configuration example of virtual space control system]
1 shows an example of the overall configuration of a virtual space control system according to this embodiment. The virtual space control system according to this embodiment includes a virtual space control device 100 and one or more user terminals 200.
The virtual space control device 100 and the user terminal 200 are communicably connected via a network.

The virtual space control device 100 constructs a three-dimensional virtual space (metaverse) in which three-dimensional art objects that are reproductions of artworks are arranged. Such a virtual space may be, for example, a reproduction of a real or virtual museum in which artworks are exhibited.
The virtual space control device 100 provides an environment in which an avatar of a user corresponding to the user terminal 200 can view artworks in a virtual art museum (virtual art museum) by having the avatar exist in the virtual space.

The user can also use the user terminal 200 to perform various operations related to the corresponding avatar, such as instructing the actions of the corresponding avatar that exists in the virtual space.

The virtual space control device 100 may be provided as a single server or other device present on a network, or may be realized by multiple servers or other devices distributed on a network, each having a specific function, coordinating with each other to execute processing.

The user terminal 200 may be a smartphone, a tablet terminal, a personal computer, a wearable VR terminal, etc.

[Overview of Art Object Extension]
The user can operate the user terminal 200 to make the avatar act as if appreciating artworks in the virtual museum. The user can see the avatar corresponding to the user appreciating artworks in the virtual museum through the image of the virtual museum displayed on the user terminal 200, and can thus appreciate the artworks in the virtual museum.

In this embodiment, when an avatar views an object artwork in a virtual art museum, the object artwork is changed so that it expands over time within the virtual art museum.

In this embodiment, two examples of the manner in which an object serving as a work of art is expanded (expansion state) are given: planar expansion and space inner wall expansion.
Planar expansion is an expansion state in which a planar object, such as a painting, expands along the plane direction over time.
The space inner wall expansion is an expansion state in which an object, which is a two-dimensional painting, expands three-dimensionally over time along the inner wall of a three-dimensional space of a predetermined shape set in the virtual art museum.

[Example of plane expansion]
An example of one aspect of plane expansion will be described with reference to FIGS.
2 shows an image of an art object OBJ, which is a painting, hung on a wall in a virtual art museum, and an avatar AVT approaching the art object OBJ. Also, in FIG. 2, an expansion trigger area AR (a trigger region, an example of an expansion state indicator) is shown at a position on the floor a predetermined distance in front of the art object OBJ.

When a user wishes to expand an art object OBJ exhibited in the virtual art museum of FIG. 2, the user operates the user terminal 200 to move the avatar AVT so that it is positioned in the expansion trigger area AR. The expansion trigger area AR indicates that planar expansion is possible for the corresponding art object OBJ, and indicates that this is the position at which a planar expansion trigger will be generated.

In response to the avatar AVT being positioned in the expansion trigger area AR, the artwork object OBJ starts expanding, starting from the state of the original artwork object OBJ shown in FIG.
3 shows the state of the artwork object OBJ after a certain time has passed since the expansion started. Arrows A to D in the figure show the directions in which the artwork object OBJ is expanded.
As shown in the figure, the artwork object OBJ is expanded in all directions, up, down, left and right, along the wall surface on which it is displayed, from the initial state in Fig. 2. In other words, the artwork object OBJ is expanded along the planar direction corresponding to the wall.

The expansion of the artwork object OBJ shown in the figure does not involve enlarging the initial painting shown in Figure 2, but rather extending it by drawing new depiction parts that are connected to the initial painting.

FIG. 4 shows a state in which the artwork object OBJ has been further expanded from the state in FIG. 3 in response to the passage of a certain amount of time since the time corresponding to the state in FIG.
In this figure, the artwork object OBJ has been expanded in all directions, up, down, left and right, from the state in Figure 3. Furthermore, as for the expanded portion in the downward direction, when it is expanded to a position corresponding to the floor, as shown by arrow B, it continues to expand further by extending forward along the floor.

FIG. 5 shows a state where a certain amount of time has elapsed since the state shown in FIG. 4, and where the expansion of the artwork object OBJ has been completed.
The artwork object OBJ in this figure has been expanded in all directions from the state in FIG. 4, and in the floor portion, it has been extended to include the expanded trigger area AR in which the avatar AVT was located.
In this state, the avatar AVT appears to be present in the environment represented by the painting, and the user viewing the video of the figure through the user terminal 200 can also have the sensation of being present in the environment represented by the painting. In other words, by expanding the art object OBJ, an environment is obtained in which the user can easily immerse himself in the worldview of the painting as the art object OBJ exhibited in the virtual art museum.

Furthermore, after the art object OBJ starts expanding, the expansion of the art object OBJ may continue even if the avatar AVT moves outside the expansion trigger area AR. In this case, the user can view the art object OBJ expanding on the floor of the virtual art museum by moving the avatar AVT and also moving the viewpoint. This allows the user to get the feeling, through the actions of the avatar AVT, that they are viewing the expanded art object OBJ right in front of them.

It should be noted that there may be avatars other than the avatar AVT that has reached the expansion trigger area AR and started expanding the art object OBJ around the art object OBJ that is the target of expansion.
In this case, the expanded state of the art object OBJ may be displayed in the same manner on the user terminal 200 of a user corresponding to an avatar other than the avatar AVT. Alternatively, conversely, the expanded state of the art object OBJ may not be reflected on the user terminal 200 of a user corresponding to an avatar other than the avatar AVT, and may be displayed as if the art object OBJ is not expanded.

When the user has finished viewing the art object OBJ, the user may perform an operation to move the avatar AVT out of the expanded art object OBJ, thereby causing the art object OBJ to return to the state shown in Figure 2 before expansion.

Note that, while the art object OBJ is being expanded, if the avatar AVT moves to a position at a predetermined distance or more from the art object OBJ, the expansion of the art object OBJ may be interrupted and the art object OBJ may be returned to the state shown in FIG. 2 before the expansion.

[Examples of space interior wall expansion]
Next, an example of the expansion of the inner wall of the space will be described with reference to FIGS.
FIG. 6 shows a state in which the avatar AVT is positioned close to one of the art objects OBJ exhibited in the virtual art museum, the art object OBJ being capable of expanding the interior wall of the space.
The artwork object OBJ in the figure is a painting that is displayed hanging on a wall in a virtual art museum. The contents of the painting as the artwork object OBJ are moved in a spiral shape around the artwork object OBJ (an example of an expansion state indication), which indicates that the interior wall of the space can be expanded for the artwork object OBJ.

When the user wishes to view the art object OBJ in the figure with the interior space wall expanded, the user performs an operation (space entry operation) on the user terminal 200 to move the avatar AVT as if moving the avatar AVT into the frame in which the art object OBJ is housed. In response to the space entry operation being performed, the avatar AVT enters the object expansion space (an example of a trigger area), which is a three-dimensional space in which the interior space wall expansion is performed.

The manner of entry into the object extension space is not limited to the above example. The manner of entry into the object extension space may be, for example, entering a room of a predetermined shape provided in a virtual art museum. In addition, the avatar AVT may be allowed to enter the object extension space in response to the user (or the avatar AVT acting in response to user operations on the user terminal 200) operating an entry button provided near the art object OBJ in the virtual art museum.

Fig. 7 shows the state when the avatar AVT enters the object extension space. In this figure, an example is shown in which the object extension space has a shape with a hemispherical top surface and a flat bottom surface. As shown in this figure, in the object extension space, the original (before extension) art object OBJ shown in Fig. 6 is used as a starting point, and the object extension space is extended so as to extend along the inner wall of the object extension space.
The object extension space is not limited to a shape having a hemispherical top surface and a flat bottom surface. The object extension space may be, for example, a rectangular parallelepiped, a cube, a triangular pyramid, a cone, or a shape having a curved surface other than a sphere.

FIG. 8 shows the state of the object extension space during extension when a certain time has elapsed from the state shown in FIG.
FIG. 9 shows the state of the object extension space during extension when a certain time has elapsed since the state shown in FIG.
FIG. 10 shows the state of the object extension space during extension when a certain time has elapsed since the state shown in FIG.
As shown in FIGS. 7 to 10, the artwork object OBJ is expanded so as to extend over time along the hemisphere of the expanded object space and the bottom surface of the inner wall.

11 and 12 show the state of the expanded object space after the expansion of the artwork object OBJ is completed.
11 and 12, the avatar AVT can move and change the viewpoint within the object extended space in which the artwork object OBJ is extended. As the avatar AVT moves within the object extended space, the viewpoint from which the artwork object OBJ is observed also changes, so the field of view of the scenery as the artwork object OBJ being observed differs between FIG. 11 and FIG. 12.

Images of the types shown in Figures 6 to 12 as described above are displayed on the user terminal 200. By viewing images displayed in this manner, the user can experience the worldview and image of the painting as the artwork object OBJ in 360 degrees in flat space. For this reason, an environment in which the user can easily become immersed can be obtained even by expanding the interior walls of the space.

In the object extension space, an exit may be provided for the avatar AVT to leave the object extension space and return to the floor of the virtual art museum. In response to the avatar AVT returning from the exit to the floor of the virtual art museum, the extension of the artwork object OBJ in the space inner wall extension space may be released.

In addition, for example, in a case where other avatars are acting together with avatar AVT, when the other avatar enters the object extension space after avatar AVT, the state of the extended art object OBJ may be made visible to the user of the other avatar in the same way as it is visible to the user of the avatar AVT that has already entered.
Alternatively, if another avatar enters the object expansion space after the avatar AVT, the user of the other avatar may be able to see the start of expansion of the art object OBJ, regardless of the avatar AVT.

[Example of functional configuration of virtual space control device]
Fig. 13 shows an example of the functional configuration of the virtual space control device 100. The functions of the virtual space control device 100 shown in the figure are realized by a central processing unit (CPU) included in the hardware of the virtual space control device 100 executing a program.
The virtual space control device 100 in the figure includes a communication unit 101, a control unit 102, and a storage unit 103.

The communication unit 101 is connected to the user terminal 200 via a network so that communication is possible.

The control unit 102 executes various controls in the virtual space control device 100. The control unit 102 includes an extended object data generation unit 121 and a virtual space control unit 122.

The extended object data generating unit 121 generates extended object data corresponding to the art object OBJ exhibited in the virtual art museum.
The extended object data is data obtained by extending an art object OBJ, as shown in Figures 2 to 10. The extended object data generating unit 121 may generate the extended object data by using data of an original art object (original object data).

The extended object data generating unit 121 may generate extended object data using a trained model that extends the content of a painting represented by the original object data in response to input of the original object data. Specifically, such a trained model may be constructed, for example, by training a trained model to generate data of surrounding objects that are naturally connected to the content of an original painting represented by the input original object, based on the content of the painting.
The extended object data generated by the extended object data generating unit 121 is stored in the extended object data storage unit 133 .

The function of the extended object data generation unit 121 may be provided by an external device other than the virtual space control device 100. In this case, the extended object data generated by the external device having the function of the extended object data generation unit 121 may be transmitted to the virtual space control device 100 via a specified transmission path, and the virtual space control device 100 may store the transmitted data in the extended object data storage unit 133.

The virtual space control unit 122 constructs the virtual art museum of this embodiment and controls the actions of the avatar AVT within the constructed virtual art museum. The virtual space control unit 122 also controls the expansion of the art object OBJ.

The storage unit 103 stores various information corresponding to the virtual space control device 100. The storage unit 103 includes a virtual space data storage unit 131, an original object data storage unit 132, and an extended object data storage unit 133.

The virtual space data storage unit 131 stores data (virtual space data) that the virtual space control unit 122 uses to construct a virtual space as a virtual museum. The virtual space construction data includes data for constructing structures as a virtual museum. It may also include audio data that reproduces sounds that are output along with the images of the virtual museum.

The original object data storage unit 132 stores original object data. The original object data is object data that reproduces an original, non-augmented artwork object OBJ exhibited in the virtual art museum.
The virtual space control unit 122 uses the original object data to reproduce the artwork object OBJ in its pre-expansion state to be exhibited in the virtual art museum.

Figure 14 shows an example structure of original object data stored by the original object data storage unit 132 in correspondence with one artwork object OBJ. As shown in the figure, the original object data corresponding to one artwork object OBJ has a structure in which an object ID that uniquely identifies the corresponding artwork object OBJ is associated with the original object data.

Returning to FIG. 13 for explanation, the extended object data storage unit 133 stores the extended object data generated by the extended object data generation unit 121.

FIG. 15 shows an example of the structure of extended object data stored in the extended object data storage unit 133 in association with one artwork object OBJ.
As shown in the figure, the extended object data corresponding to one original object has a structure in which an object ID that uniquely indicates the corresponding artwork object OBJ is associated with the extended object data.
The extended object data stored in the extended object data field in the same figure becomes planar extended object data that reproduces the planar expansion of the corresponding art object OBJ if the corresponding art object OBJ is configured to be extended in a plane, and becomes intra-space extended object data that reproduces the spatial inner wall expansion of the art object OBJ if the corresponding art object OBJ is configured to be extended in a space.

As can be seen from Figures 14 and 15, in this embodiment, the original object data and extended object data corresponding to the same artwork object OBJ are stored in association with the object ID assigned to the corresponding artwork object OBJ. This makes it possible to associate the original object data and extended object data corresponding to the same artwork object OBJ.

Note that not all artwork objects OBJ exhibited in the virtual art museum may be made extensible, and only some of the artwork objects OBJ exhibited in the virtual art museum may be made extensible. In this case, the extended object data storage unit 133 may store extended object data that corresponds to the original object data that is made extensible for the corresponding artwork object OBJ, among all the original object data stored in the original object data storage unit 132.

[Example of processing procedure]
An example of a processing procedure executed by the virtual space control device 100 of this embodiment in relation to the expansion of the artwork object OBJ will be described with reference to the flowchart in Fig. 16. The processing in the figure may be common to both the planar expansion and the space inner wall expansion.

Step S100: In the virtual space control device 100, the virtual space control unit 122 waits for an expansion trigger to occur.
When the target artwork object OBJ is a plane expansion type, the expansion trigger is generated in response to the avatar AVT reaching the expansion trigger area AR. When the target artwork object OBJ is a space inner wall expansion type, the expansion trigger is generated in response to the virtual space control unit 122 accepting a space entry operation performed on the user terminal 200.

Step S102: When an expansion trigger occurs, the virtual space control unit 122 acquires the expanded object data associated with the object ID of the target artwork object OBJ from the expanded object data storage unit 133.

Step S104: The virtual space control unit 122 expands the artwork object OBJ by expanding the plane or the interior wall of the space by playing back the acquired extended object data.

Step S106: The virtual space control unit 122 determines whether or not an operation for moving the avatar AVT within the expanded range has been performed while the artwork object OBJ is in the expanded range.
In the case of planar expansion, the expansion range here may be, for example, the range of the artwork object OBJ expanded on the floor of the virtual art museum. In the case of space inner wall expansion, the expansion range may be within the object expansion space.

Step S108: In response to an operation to move the avatar AVT within the extended range, the virtual space control unit 122 moves the avatar AVT within the extended range in a direction and at a speed according to the operation.

Step S110: If it is determined in step S106 that no operation to move the avatar AVT has been performed, or after the processing of step S108, the virtual space control unit 122 determines whether or not an operation to change the viewpoint (a viewpoint change operation) has been performed on the user terminal 200. The viewpoint changed by the viewpoint change operation may be specified as the line of sight direction of the avatar AVT, or may be specified arbitrarily regardless of the avatar AVT.

Step S112: When a viewpoint change operation is performed, the virtual space control unit 122 changes the viewpoint to the one specified by the viewpoint movement operation.

By processing steps S106 to S112, when the avatar AVT is present within the extended range, the user can operate the user terminal 200 to move the avatar AVT and change the viewpoint.

Step S114: If it is determined in step S110 that the viewpoint change operation has not been performed, or after the process of step S112, the virtual space control unit 122 determines whether or not the avatar AVT has moved outside the extension range.
If it is determined that the avatar AVT has not moved outside the expansion range, the process returns to step S106.

Step S116: When the avatar AVT moves outside the expansion range, the virtual space control unit 122 cancels the expansion of the artwork object OBJ.

<Modification>
Modifications of this embodiment will be described below. The following modifications may be combined as appropriate.

For example, when an art object OBJ such as a painting depicting a landscape is expanded, it may be possible to display, for example, the wind blowing grass and trees, a person's hair and clothing, moving clouds, etc. In this case, expanded object data generated to give movement to the expanded art object OBJ may be used.
Furthermore, by including sound data in the extended object data, sounds of people, animals, wind, a flowing river, rain, etc. that can be heard in the surroundings may be output by the user terminal 200 depending on the content of the art object OBJ.

For example, when an art object OBJ such as a painting depicting an outdoor scene is being expanded, the current real weather conditions may be reflected.
Specifically, as the appearance of the spatial range into which the art object OBJ is extended, if the current weather is sunny, for example, the sun and shade may be clearly defined to indicate that it is sunny, and if the current weather is rainy, it may be depicted as if it is raining in the spatial range into which the art object OBJ is extended.
To change the representation of the enlarged artwork object OBJ in accordance with the real weather in this manner, for example, the extended object data generation unit 121 may obtain the current weather from a website or the like that provides weather information via the communication unit 101, and generate extended object data that reflects the obtained weather. The virtual space control unit 122 plays back the generated extended object data, whereby the artwork object OBJ is expanded so that a depiction that reflects the current weather is added.

In the above embodiment, the expansion is performed starting from the entire original art object OBJ, but the expansion may be performed starting from a specified part of the original art object OBJ. Also, the art object OBJ in its original state exhibited in the virtual art museum may be exhibited in its entirety, or only a specified part of it.

In this embodiment, the art objects that are the subject of expansion are not limited to paintings, but may be, for example, sculptures, photographs, sculptures, calligraphy, ceramics, crafts, and other reproductions of art. Furthermore, the objects that are the subject of expansion are not limited to art, but may be, for example, photographs, drawings by young children, various plants such as flowers and fruits, and specified items that are provided in homes in the virtual space.

In addition, a program for realizing the functions of the above-mentioned virtual space control device 100 and the user terminal 200 may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform the processing of the above-mentioned virtual space control device 100 and the user terminal 200. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including the Internet, WAN, LAN, dedicated lines, and other communication lines. In addition, the "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as HDDs and SSDs built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. In addition, the recording medium also includes a recording medium provided inside or outside and accessible from a distribution server to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by the terminal device. In other words, as long as it can be downloaded from the distribution server and installed in a format executable by the terminal device, the format in which it is stored in the distribution server does not matter. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a memory that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or client when a program is transmitted over a network. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
