[0003] In the virtual space, participants can interact with other participants by operating virtual characters called avatars. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] "VR Event "Sword Art Online Synthesis -The Period of Alicization Project-"", [online], Kayac Inc., [Retrieved October 12, 2021], Internet<URL:https: / / www.kayac.com / service / client / 1773> Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, in such virtual spaces, there are cases where an avatar (first avatar) operated by a human using a terminal interacts with an avatar (second avatar) operated independently by the terminal.

[0006] In such cases, it is difficult for conventional systems to distinguish between a first avatar operated by a human using a terminal and a second avatar operated independently by the terminal.

[0007] Therefore, the present invention has been made in consideration of the above circumstances, and aims to provide a determination system that can distinguish between an avatar operated by a human using a terminal and an avatar operated independently by the terminal. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, a determination system according to the present invention comprises a plurality of terminals connectable to a network, and a server connectable to the plurality of terminals via the network, the server having a server recording device capable of recording data, and a server control device that forms a virtual space on the network based on the data recorded in the server recording device, each of the plurality of terminals having a terminal control device that comprehensively controls the terminal, and a terminal recording device that can record the data, and the plurality of terminals include a first terminal that causes a first avatar to act in the virtual space in response to an operation by an operator, and a second terminal that causes a second avatar to act in the virtual space based on the data recorded in the terminal recording device. and two terminals, wherein the server control device forms the first avatar and the second avatar in the virtual space, causes the first avatar and the second avatar to act in the virtual space using each of the multiple terminals, records the actions of the first avatar in the server recording device, and records the actions of the second avatar in the server recording device, transmits judgment information that can only be identified by either the operator of the first terminal that operates the first avatar or the second terminal that operates the second avatar to each of the multiple terminals, and records the reaction of the first avatar to the judgment information and the reaction of the second avatar to the judgment information in an operation server recording device.

[0009] In the determination system according to the present invention, the server control device transmits, to each of the plurality of terminals, determination information that can be identified only by the second terminal operating the second avatar.

[0010] In the determination system of the present invention, the first terminal has a first output device that outputs sound in the virtual space to an operator, and the determination information is the sound that the operator cannot hear but can hear the second terminal.

[0013] [Embodiment] Modes (embodiments) for carrying out the present invention will be described in detail below with reference to the drawings. The present invention is not limited to the contents described in the following embodiments. Furthermore, the components described below include those that can be easily imagined by a person skilled in the art and those that are substantially the same. Furthermore, the configurations described below can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the configuration can be made within the scope of the gist of the present invention.

[0014] First, the configuration of a determination system 1 according to an embodiment will be described below. FIG. 1 is a block diagram conceptually explaining the determination system 1 according to this embodiment. FIG. 2 is a block diagram conceptually explaining each of the terminals 2 provided in the determination system 1 shown in FIG. 1. FIG. 3 is a block diagram conceptually explaining the operation server 3 provided in the determination system 1 shown in FIG. 1. FIG. 4 is a block diagram conceptually explaining the management server 4 provided in the determination system 1 shown in FIG. 1. FIG. 5 is a perspective view showing a virtual space VS formed by the operation server 3 shown in FIG. 3. FIG. 6 is an explanatory diagram showing a first avatar AV1 and a second avatar AV2 in the virtual space VS shown in FIG. 5.

[0015] As shown in Figure 1, the determination system 1 in this embodiment includes, for example, a plurality of terminals 2 connectable to a network (for example, the Internet) NT1, an operation server 3 connectable to the plurality of terminals 2 via the network NT1, and a management server 4 connectable to the operation server 3 via the network NT1.

[0016] Each of the plurality of terminals 2 is, for example, an electronic computer such as a personal computer, etc. Each of the plurality of terminals 2 is connected to the network NT1 via a connection line W, for example.

[0017] Each of the multiple terminals 2 includes a terminal control device 21 and a terminal recording device 22. The terminal control device 21 comprehensively controls each unit of the terminal 2. The terminal recording device 22 stores various data such as programs that operate each unit of the terminal 2. In addition, the terminal control device 21 can record various data in the terminal recording device 22.

[0018] The terminal 2 also includes a terminal input device 23 such as a mouse 23a and a keyboard 23b, and a terminal output device 24 such as a display 24a and a speaker 24b.

[0019] The multiple terminals 2 include a first terminal 2α that causes a first avatar AV1 (AV (see FIG. 6)) to act in the virtual space VS in response to operations by a human operator, and a second terminal 2β that causes a second avatar AV2 (AV (see FIG. 6)) to act in the virtual space VS based on data recorded in a terminal recording device 22. In other words, the second terminal 2β causes the second avatar AV2 to act in the virtual space VS based only on the data recorded in the terminal recording device 22, without operations by a human operator.

[0020] In the determination system 1 according to this embodiment, the configuration of the first terminal 2α and the configuration of the second terminal 2β are the same, so the same reference numerals are used and the description thereof is omitted. In addition, in the determination system 1 according to this embodiment, the settings of the first terminal 2α are unchanged, and the settings of the second terminal 2β are also unchanged. In other words, in the determination system 1 according to this embodiment, the settings of the first terminal 2α are never changed to the second terminal 2β, and the settings of the second terminal 2β are never changed to the first terminal 2α.

[0021] On the first terminal 2α, for example, initial registration is completed by downloading the software or application (hereinafter simply referred to as "app") for the virtual space VS from the homepage about the virtual space VS described below, and entering specified data such as the operator's email address into the specified field on the homepage using the terminal input device 23.

[0022] Furthermore, at the time of initial registration, a password for each first terminal 2α to enter the virtual space VS is set between the operator of each first terminal 2α and the management server control device 31.

[0023] Thereafter, when the operator inputs a password or the like into the terminal input device 23, the first terminal 2α is connected to the management server 3, allowing the operator to operate the first avatar AV1 in the virtual space VS, and the virtual space VS is displayed on the display 24a.

[0024] The first avatar AV1 can be operated by the operator via the terminal input device 23 and is a person who serves as the operator's alter ego in the virtual space VS. The operator who operates the first terminal 2α may, for example, use an online shopping service at multiple virtual stores located in the virtual space VS. The operator who operates the first terminal 2α may also interact with operators of other first avatars AV1 who are active in the virtual space VS.

[0025] Next, the relationship between the operation of the terminal input device 23 and the first avatar AV1 will be described. When the operator presses "↑" on the keyboard 23b, the first avatar AV1 moves forward in the forward / backward direction in the virtual space VS. When the operator presses "↓" on the keyboard 23b, the first avatar AV1 moves backward in the forward / backward direction in the virtual space VS. When the operator presses "→" on the keyboard 23b, the first avatar AV1 moves right in the left / right direction in the virtual space VS. When the operator presses "←" on the keyboard 23b, the first avatar AV1 moves left in the left / right direction in the virtual space VS.

[0026] Furthermore, the operator operating the first terminal 2α of the first avatar AV1 can interact with operators operating other first avatars AV1 by inputting information on the keyboard 23b or the like.

[0027] The second terminal 2β has been registered in advance with the operation server 3. The second terminal 2β is connected to the operation server 3 at an appropriate timing, and the second avatar AV2 can be operated in the virtual space VS by the terminal control device 21 based on data previously recorded in the terminal recording device 22. In other words, the second avatar AV2 can perform actions such as movement in the virtual space VS.

[0028] In the second terminal 2β, the audible range of the terminal control device 21 can be set appropriately. For example, the audible range of the terminal control device 21 is 20 Hz to 50 kHz.

[0029] The operation server 3 is, for example, an electronic computer such as a workstation. For convenience of explanation, the operation server 3 according to this embodiment will be described as a single electronic computer, but it may also be configured as a cloud system in which multiple workstations operate in cooperation. Furthermore, for convenience of explanation, the operation server 3 according to this embodiment will be described as having a function of providing online shopping services through an EC site (electronic commerce site) and a function of forming a virtual space VS in the network NT1, but it is also possible to provide separate operation servers 3 having each of these functions.

[0030] The management server 3 is connected to the network NT1 via a connection line W, for example. The management server 3 is connected to each of the terminals 2 via the network NT1. The management server 3 includes an management server control device 31 and an management server recording device 32.

[0031] The operation server control device 31 comprehensively controls each unit of the operation server 3. The operation server control device 31 also forms a virtual space VS on the network NT1 based on data recorded in the operation server recording device 32. More specifically, the operation server control device 31 forms a virtual space VS in which each avatar (registered trademark) AV of a terminal 2 connectable to the operation server 3 can act. Furthermore, the operation server control device 31 forms avatars AV (i.e., a first avatar AV1 and a second avatar AV2) in the virtual space VS. The operation server control device 31 also causes the first avatar AV1 and the second avatar AV2 to act in the virtual space VS via each of the multiple terminals 2. Furthermore, the operation server control device 31 records the actions of the first avatar AV1 in the virtual space VS in the operation server recording device 32, and also records the actions of the second avatar AV2 in the virtual space VS in the operation server recording device 32. In other words, the administration server control device 31 tracks the behavior of each avatar AV in the virtual space VS and records each of the avatar AV's behaviors (movement, interactions (communication) with other avatar AV) in the administration server recording device 32. Furthermore, as will be described later, the administration server control device 31 transmits to the multiple terminals 2 determination information that can only be identified by either the operator of the first terminal 2α operating the first avatar AV1 or the second terminal 2β operating the second avatar AV2. The administration server control device 31 then records the reaction of the first avatar AV1 to the determination information and the reaction of the second avatar AV2 to the determination information in the administration server recording device 32 and transmits the reactions to the management server 4.

[0032] As shown in Fig. 5, the virtual space VS includes a plurality of virtual stores VSh. For example, the virtual space VS includes a first virtual store VSh1, a second virtual store VSh2, and a third virtual store VSh3. The virtual space VS according to this embodiment is, for example, three-dimensional. More specifically, in the virtual space VS shown in Fig. 4, for example, the Z-axis direction, which is the up-down direction, the X-axis direction, which is the front-back direction, and the Y-axis direction, which is the left-right direction, are mutually orthogonal.

[0033] In other words, in the virtual space VS, a plurality of virtual stores VSh, including a first virtual store VSh1, a second virtual store VSh2, and a third virtual store VSh3, are formed by the operation server control device 31. An operator of the first terminal 2α, who operates the first avatar AV1, can purchase virtual products and real products in the virtual store VSh. Also, as shown in FIG. 6, in the virtual space VS, the first avatar AV1 and the second avatar AV2 can interact with each other. Furthermore, although not shown, in the virtual space VS, a certain first avatar AV1 can interact with another first avatar AV1.

[0034] The operation server recording device 32 stores various data such as programs that operate each part of the operation server 3. The operation server recording device 32 also stores data that forms a virtual space VS on the network NT1. Furthermore, the operation server control device 31 can record data in the operation server recording device 32.

[0035] The management server 3 also includes a management server input device 33 such as a mouse 33a and a keyboard 33b, and a management server output device 34 such as a display 34a.

[0036] The management server 4 is, for example, a computer such as a workstation, etc. The management server 4 has a function of managing the operation server 3.

[0037] The management server 4 is connected to, for example, a network NT1 via a connection line W. The management server 4 is connected to a plurality of terminals 2 via the network NT1. The management server 4 includes a management server control device 41 and a management server recording device 42.

[0038] The management server control device 41 comprehensively controls each unit of the management server 4. When data on the results of a determination process described below is transmitted from the operation server 3, the management server control device 41 determines, based on the reaction of each terminal 2, whether it is the first terminal 2α that causes the first avatar AV1 to act in the virtual space VS in response to the operator's operation, or the second terminal 2β that causes the second avatar AV2 to act in the virtual space VS based on the data recorded in the terminal recording device 22.

[0039] Then, if the management server control device 41 is the first terminal 2α that causes the first avatar AV1 to act in the virtual space VS in response to the operator's operation, the management server control device 41 assigns data to the first terminal 2α indicating that the operator is a human.

[0040] On the other hand, if the second terminal 2β is one that causes the second avatar AV2 to act in the virtual space VS based on the data recorded in the terminal recording device 22, the management server control device 41 assigns data to the second terminal 2β indicating that the operator is not human.

[0041] The management server recording device 42 stores various data, such as programs that operate the various components of the management server 4. Furthermore, the management server control device 41 can record data in the management server recording device 42. When performing a determination process (described later), the management server 4 according to this embodiment receives from the administration server 3 "the reaction of the first avatar AV1 to the determination information and the reaction of the second avatar AV2 to the determination information." The management server control device 41 then records the data in the management server recording device 42. Based on the reaction of the first avatar AV1 to the determination information and the reaction of the second avatar AV2 to the determination information, the management server control device 41 determines, for each terminal 2, whether the operator is the first terminal 2α that controls the first avatar AV1, or the second terminal 2β that controls the second avatar AV2 in the virtual space VS based on the data recorded in the terminal recording device 22.

[0042] The management server 4 also includes a management server input device 43 such as a mouse 43a and a keyboard 43b, and a management server output device 44 such as a display 44a.

[0043] Next, the determination process performed by the operations server control device 31 of the operations server 3 will be described with reference to Fig. 7. Fig. 7 is a flow diagram of the determination process performed by the operations server control device 31 shown in Fig. 3.

[0044] First, the operation server control device 31 waits for a predetermined time to elapse (step S01). The "predetermined time" is, for example, one hour. The "predetermined time" can be changed by the operation server input device 33 or the management server input device 43.

[0045] Next, the operations server control device 31 determines whether or not a judgment test command has been sent from the management server control device 41 (step S02). If a judgment test command has been sent from the management server control device 41 (step S02: Yes), the operations server control device 31 proceeds to step S03. On the other hand, if a judgment test command has not been sent from the management server control device 41 (step S02: No), the operations server control device 31 returns to step S01.

[0046] The management server control device 41 transmits a judgment test command to the operation server 3, for example, once a day (for example, at the time when the number of avatars AV in the virtual space AV is the greatest).

[0047] Next, the administration server control device 31 transmits the determination information to all avatars AV existing in the virtual space VS (step S03), and proceeds to step S04.

[0048] Next, the administration server control device 31 records the avatar AV's reaction to the judgment information (step S04), and then ends this process.

[0049] More specifically, the administration server control device 31 records the reaction of the first avatar AV1 to the judgment information, and also records the reaction of the second avatar AV2 to the judgment information. Furthermore, the administration server control device 31 transmits to the management server 4 the reaction of the first avatar AV1 to the judgment information and the reaction of the second avatar AV2 to the judgment information.

[0050] The human hearing range is approximately 20 Hz to 20 kHz. Therefore, in the above-mentioned determination process, the determination information transmitted to each avatar AV is, for example, a sound of 30 kHz to 40 kHz. The content of the sound may be, for example, that the avatar that hears the sound raises its hand.

[0051] In response to such determination information, the operator of the terminal operating the first avatar AV1 cannot recognize the sound because it is beyond the audible range, and therefore will not perform an operation to make the avatar raise its hand.

[0052] In response to such determination information, the terminal operating the second avatar AV2 can hear sounds in the 30 kHz to 40 kHz range, and therefore can recognize the sound, causing the avatar to raise its hand.

[0053] In other words, the above-mentioned determination information is a sound that cannot be heard by the human operator of first terminal 2α, but can be heard by second terminal 2β. Then, management server control device 41 can easily determine whether the operator of the avatar AV is a human or not, based on the presence or absence of a response to the determination information.

[0054] As described above, the determination system 1 according to this embodiment includes a plurality of terminals 2 connectable to a network NT1 and an operation server 3 connectable to the plurality of terminals 2 via the network NT1. The operation server 3 includes an operation server recording device 32 capable of recording data and an operation server control device 31 that forms a virtual space VS on the network NT1 based on the data recorded in the operation server recording device 32. Each of the plurality of terminals 2 includes a terminal control device 21 that comprehensively controls the terminal and a terminal recording device 22 that can record data. The plurality of terminals 2 includes a first terminal 2α that causes a first avatar AV1 to act in the virtual space VS in response to an operation by an operator, and a second terminal 2β that causes a second avatar AV2 to act in the virtual space VS based on the data recorded in the terminal recording device 22. The operation server control device 32 forms the first avatar AV1 and the second avatar AV2 in the virtual space VS, and causes the first avatar AV1 and the second avatar AV2 to act in the virtual space VS using each of the plurality of terminals 2. The operation server control device 32 also records the behavior of the first avatar AV1 in the operation server recording device 32, and also records the behavior of the second avatar AV2 in the operation server recording device 32. Furthermore, the operation server control device 32 transmits determination information that can only be identified by the second terminal 2β operating the second avatar AV2 to each of the multiple terminals 2. Furthermore, the operation server control device 32 records the reaction of the first avatar AV1 to the determination information and the reaction of the second avatar AV2 to the determination information in the operation server recording device 32. Therefore, according to the determination system 1 of this embodiment, it is easy to determine for each terminal 2 whether the operator is the first terminal 2α operating the first avatar AV1 or the second terminal 2β causing the second avatar AV2 to act in the virtual space VS based on the data recorded in the terminal recording device 32, based on the reaction of the first avatar AV1 to the determination information and the reaction of the second avatar AV2 to the determination information. Therefore, the management server control device 41 of the determination system 1 of this embodiment can distinguish between the first avatar AV1 operated by a human operator using the first terminal 2α and the second avatar AV2 operated independently by the second terminal 2β.

[0055] The administrator operating the management server 4 can, for example, send specified information via the management server 3 only to the second terminal 2β, whose operator is not human, or send specified information via the management server 3 only to the first terminal 2α, whose operator is human.

[0056] More specifically, the administrator who operates the management server 4 can investigate whether the terminal 2 is the first terminal 2α or the second terminal 2β at any timing by operating the management server input device 43. Then, based on that investigation, for example, when transmitting advertising data that only the human operator is interested in to an avatar AV existing in the virtual space VS, the administrator can prevent unnecessary advertising data from being sent by transmitting the advertising data only to the first terminal 2α while not transmitting the advertising data to the second terminal 2β.

[0057] Furthermore, in the determination system 1, the administration server control device 31 transmits to each of the multiple terminals 2 determination information that can identify only the second terminal 2β that operates the second avatar AV2.

[0058] In addition, in the determination system 1, the first terminal 2α has a terminal output device 24 that outputs sounds in the virtual space VS to the operator, and the determination information is sounds that the operator cannot hear but that the second terminal 2β can hear.

[0059] In the determination system 1 according to the embodiment described above, the determination information is information (sound) that can be identified only by the second terminal 2β operating the second avatar AV2. However, the determination information is not limited to the above.

[0060] Another example of the determination information is described below. In this example, the determination information is an email stating that if the avatar AV visits a specific virtual store VSh within the virtual space VS, a predetermined number of points will be presented free of charge.

[0061] In response to such determination information, the operator of the first terminal 2α operating the first avatar AV1 can receive points for free, and can therefore have the first avatar AV1 visit a specific virtual store VSh.

[0062] In response to such determination information, the second terminal 2β operating the second avatar AV2 is not interested in points and therefore does not cause the second avatar AV2 to visit the specific virtual store VSh.

[0063] Therefore, in the above example, the operation server control device 32 transmits determination information that can only be identified by the operator of the first terminal 2α operating the first avatar AV1 to each of the multiple terminals 2. Then, the operation server control device 32 records in the operation server recording device 32 the first terminal 2α operating the first avatar AV1 that responded to the determination information.

[0064] In other words, the determination information is information that can only be identified by the operator of the first terminal 2α operating the first avatar AV1. Therefore, in this example, the operation server control device 32 records in the operation server recording device 32 the first terminal 2α operating the first avatar AV1 that responded to the determination information.

[0065] In the determination system 1 according to the present embodiment, the settings of the first terminal 2α and the second terminal 2β are unchanged. However, the determination system 1 according to the present embodiment is not limited to this. For example, an operator can use the terminal input device 23 to perform a special operation at any time to set the terminal 2 set as the second terminal 2β to the first terminal 2α, and can also set the terminal 2 set as the first terminal 2α to the second terminal 2β. In this case, when the above-described determination process is performed, the management server control device 31 records data such as the date and time of the determination process and the avatar AV's reaction to the determination information in the management server recording device 32 and transmits the data to the management server 4. In the management server 4, the management server control device 41 records the data transmitted from the management server 4 in the management server recording device 42. It is also possible to provide a setting icon on the edge of the display 24a of the terminal 2 and perform a special operation at any time by operating the icon using the terminal input device 23.

[0066] The terminal 2 of the determination system 1 according to the above embodiment has been described as an electronic computer such as a personal computer, but the terminal 2 according to the present embodiment is not limited to this and may be, for example, a smartphone.

[0067] Furthermore, the terminal output device 24 of the terminal 2 according to the above-described embodiment has been described as including the display 24a and the speaker 24b. However, the terminal output device 24 according to the present embodiment is not limited to this. For example, the terminal output device 24 may include an HMD (head-mounted display).

[0068] In the determination system 1 according to the embodiment described above, the first terminal 2α and the second terminal 2β have the same configuration. However, the determination system 1 according to the present embodiment is not limited to this. For example, the first terminal 2α and the second terminal 2β may have different configurations. More specifically, the second terminal 2β may not have a terminal output device 24.

[0069] Furthermore, the determination system 1 according to the above-described embodiment has been described as including the operation server 3 and the management server 4. However, the determination system 1 according to the present embodiment is not limited to this. For example, in the determination system 1, the operation server 3 may have the functions of the management server 4.

[0070] In addition, in the initial registration of the determination system 1 according to the embodiment described above, other conditions such as the operator's credit card number may be added. [Explanation of symbols]
