[0023] The recording medium of the present invention is a computer-readable recording medium that stores the program of the present invention.

[0024] In this invention, "virtual travel" refers to a technology that provides tourists with a virtual travel experience using the internet. Virtual travel is also called, for example, a virtual tour, simulated travel, remote sightseeing, or online tour. Virtual travel is carried out, for example, by real-time communication between a guide's terminal and a tourist's terminal. The guide, for example, provides a guide to the tourist while distributing videos and images of tourist destinations around the world to the tourist. This allows the tourist to experience virtual travel. On the other hand, the virtual travel may also be a tour that is carried out without real-time communication between the guide's terminal and the tourist's terminal. The virtual travel that communicates in real time can also be described as a technology that is held at a predetermined date and time and provides tourists with a travel experience online. Furthermore, the guide may or may not participate in the virtual travel. The videos and images are not particularly limited as long as they relate to the tourist destination, and may include, for example, 360-degree videos (videos that capture 360 ​​degrees in all directions).

[0025] The aforementioned virtual travel may take place in, for example, real space and virtual space. A virtual travel held in the real world is, for example, a travel experience that is completed on a terminal. More specifically, this could be a travel experience in which a guide streams videos and images on a terminal, and tourists view the streamed videos and images. A virtual travel held in virtual space is, for example, a travel experience that takes place in a space such as VR (virtual reality) or the metaverse.

[0026] Next, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments. In the following drawings, the same parts are denoted by the same reference numerals. Furthermore, unless otherwise specified, the descriptions of each embodiment can be used interchangeably with those of the others, and unless otherwise specified, the configurations of each embodiment can be combined.

[0027] [Embodiment 1] Figure 1 is a block diagram showing an example configuration of the interest level estimation device 10 of this embodiment. As shown in Figure 1, the device 10 includes an acquisition unit 11, an analysis unit 12, and an interest level estimation unit 13.

[0028] The device 10 may be, for example, a single device including the aforementioned parts, or it may be a device in which each of the aforementioned parts can be connected via a communication network. Furthermore, the device 10 can be connected to an external device described later via the communication network. The communication network is not particularly limited and can use a known network, for example, it may be wired or wireless. Examples of the communication network include the Internet, WWW (World Wide Web), telephone lines, LAN (Local Area Network), SAN (Storage Area Network), DTN (Delay Tolerant Networking), LPWA (Low Power Wide Area), L5G (Local 5G), etc. Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, LPWA, etc. The wireless communication may be in the form of direct communication between devices (Ad Hoc communication), infrastructure communication, indirect communication via an access point, etc. The device 10 may be, for example, incorporated into a server as a system. Furthermore, the device 10 may be, for example, a personal computer (PC, e.g., desktop or notebook type), smartphone, tablet terminal, etc., on which the program of the present invention is installed. Moreover, the device 10 may be in a form such as cloud computing or edge computing, where, for example, at least one of the aforementioned parts is on a server and the other aforementioned parts are on a terminal.

[0029] Figure 2 shows an example block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, memory 102, bus 103, storage device 104, input device 105, output device 106, communication device 107, etc. Each part of the device 10 is interconnected via the bus 103 through its respective interface (I / F). These are examples only, and the hardware configuration of the device 10 is not limited to this, as long as each part can perform its respective processing. Also, the number of central processing units 101 etc. included in the device 10 is not limited to the example in Figure 2; for example, multiple central processing units 101 may be included in the device 10.

[0030] The central processing unit 101 is responsible for the overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program of the present invention and other programs, and also reads and writes various types of information. Specifically, for example, the central processing unit 101 functions as an acquisition unit 11, an analysis unit 12, and an interest level estimation unit 13.

[0031] Bus 103 can also be connected to external devices, for example. Examples of such external devices include external storage devices (external databases, etc.), printers, external input devices, external display devices, and external imaging devices. The device 10 can be connected to an external network (the aforementioned communication network) via a communication device 107 connected to bus 103, for example, and can also be connected to other devices via the external network.

[0032] Memory 102 may be, for example, main memory. When the central processing unit 101 performs processing, memory 102 reads various operational programs, such as the program of the present invention, stored in the storage device 104 (described later), and the central processing unit 101 receives data from memory 102 and executes the program. The main memory may be, for example, RAM (random access memory). Alternatively, memory 102 may be, for example, ROM (read-only memory).

[0033] The storage device 104 is also called an auxiliary storage device, for example, in relation to the main memory (primary memory). As described above, the storage device 104 stores an operating program including the program of the present invention. The storage device 104 may be, for example, a combination of a recording medium and a drive for reading and writing to the recording medium. The recording medium is not particularly limited and may be internal or external, for example, an HD (hard disk), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, memory card, etc. The storage device 104 may be, for example, a hard disk drive (HDD) in which the recording medium and the drive are integrated, or a solid state drive (SSD).

[0034] In this device 10, the memory 102 and storage device 104 can also store various types of information, such as log information, information obtained from an external database (not shown) or external devices, information generated by this device 10, and information used by this device 10 when executing processing. At least some of this information may be stored, for example, on an external server other than the memory 102 and storage device 104, or it may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0035] The device 10 may further include, for example, a user interface such as an input device 105 and an output device 106. The input device 105 is a device for inputting, for example, characters, numbers, the position of objects displayed on the screen, images, sounds, etc. Specifically, examples include a digitizer (touch panel, etc.), keyboard, mouse, scanner, imaging device, microphone, sensor, etc. The output device 106 is a display device (LED display, liquid crystal display), printer, speaker, etc. The input device 105 and the output device 106 may also be a user interface such as a touch panel that combines them.

[0036] Next, an example of the interest level estimation method of this embodiment will be explained based on the flowchart in Figure 3. The interest level estimation method of this embodiment is carried out as follows, for example, using the interest level estimation device 10 in Figure 1. Note that the interest level estimation method of this embodiment is not limited to the use of the interest level estimation device 10 in Figure 1.

[0037] In the interest level estimation method of this embodiment, the process performed by the acquisition unit 11 is the acquisition process, the process performed by the analysis unit 12 is the analysis process, and the process performed by the interest level estimation unit 13 is the interest level estimation process.

[0038] First, the acquisition unit 11 acquires reaction data relating to the reactions of tourists participating in the virtual tour (S11). The reaction data may include, for example, video data (including video data and audio data, etc.) of the tourists, text data in chats, audio data, and responses to questionnaires. The reaction data may be acquired during the virtual tour or after the virtual tour. The reaction data may be recorded by, for example, an input device 105 such as an imaging device or microphone, and an external device (for example, an imaging device on the tourist's terminal). The video data may be, for example, live video in which the provision of the virtual tour and the imaging of the tourists are performed in real time. The virtual tour may be provided (distributed) by, for example, this device 10, by the advertising information generation device 20 described in embodiments 3 and 4 below, or by an external device. The method for providing the virtual tour is not particularly limited, and known methods can be used. Furthermore, the acquisition unit 11 may, for example, acquire reaction data related to the guide (video data (including video data and audio data, etc.), text data, responses to questionnaires, etc.) linked to the reaction data related to the tourist, as well as videos and images displayed to the tourist during the virtual trip.

[0039] The video data includes, for example, a video containing the tourist's face and a video containing an avatar representing the tourist. The avatar may, for example, trace the tourist's face and be capable of expressing the tourist's facial expressions in real time or not. By using an avatar capable of expressing the tourist's facial expressions, it is possible to grasp the tourist's reactions even in a virtual trip held in a virtual space such as the metaverse. On the other hand, the avatar may also be, for example, an avatar that does not trace the tourist's face or an avatar that does not express the tourist's facial expressions. The video containing the avatar may, for example, be a video containing the face of an avatar corresponding to the tourist's face, or a video containing the full body of an avatar corresponding to the tourist's full body. Note that the tracing of the tourist's face and the avatarization of the tourist may be performed when the acquisition unit 11 acquires the video data, or it may be performed by the tourist's terminal or another device that mediates between the tourist's terminal and this device 10. By using the avatar, for example, the anonymity of the tourist can be improved. The video data may also include, for example, a selfie video or a live video. The aforementioned live video is, for example, a video in which the tourists are filmed (and turned into avatars) in parallel with the provision of the virtual tour. The video may, for example, be a video with sound.

[0040] The content of the aforementioned questionnaire is not particularly limited and may include, for example, the number of tourists, age, gender, reason for participation, how they learned about the virtual tour, how they booked the virtual tour, what they consider a reasonable tour price for the virtual tour, whether they have prior sightseeing experience in the tour area, their evaluation score for each guided spot, their satisfaction level, spots they would have liked more explanation about, other spots they would like to be shown, other experiences they would like to be explained, areas for improvement in the guide, the type of device used to participate in the virtual tour, any problems with the device, whether they would like to participate in a real tour, and what they would consider a reasonable price for a real tour. Furthermore, the aforementioned questionnaire and its responses may be analog information written on printed media such as paper, or digital information written on a website, etc. In the case of analog information, the acquisition unit 11 may, for example, use technology such as optical character recognition to convert the questionnaire responses into digital information and acquire them.

[0041] Next, the analysis unit 12 analyzes the reaction data (S12, analysis step). Specifically, for example, the content of the tourist's remarks, the wavelength of the voice, facial expressions, etc., are analyzed from the reaction data. The method of analysis is not particularly limited and may include, for example, emotion analysis, impression analysis, scoring of the tourist's reaction, etc., and known algorithms may be used. The analysis unit 12 may, for example, convert the voice data into text data and use it for the analysis.

[0042] Then, the interest level estimation unit 13 estimates an interest level for each tourist, indicating the degree of interest in the actual trip, based on the results of the analysis (S13, interest level estimation process), and terminates (END). The interest level may be expressed as a numerical value, for example, or as words such as "interested" or "not interested." The words used are not particularly limited. If the interest level is expressed as a numerical value, for example, a higher numerical value means a higher level of interest. The interest level estimation unit 13 may, for example, estimate the interest level for each time period in the ongoing virtual trip.

[0043] Steps (S11) to (S13) may be repeated while the virtual trip is being delivered.

[0044] According to this embodiment, by analyzing the reactions (reaction data) of the tourists, it is possible to estimate the degree of interest that tourists participating in the virtual trip have in real-world travel. By utilizing this level of interest, the provider of the virtual trip can, for example, efficiently promote real-world travel, revise the content and price of the virtual trip, or plan new virtual trips.

[0045] [Embodiment 2] An example of the analysis performed by the analysis unit 12 and the estimation of interest level by the interest level estimation unit 13 will be specifically described. Note that these are illustrative examples, and the analysis performed by the analysis unit 12 and the estimation of interest level by the interest level estimation unit 13 are not limited to the content of this embodiment.

[0046] The following explanation uses text data (including converted audio data) as an example of reaction data, but as mentioned above, it is not limited to this. The analysis unit 12 stores, for example, the text data transmitted (spoken) by the tourist and the time the transmission (spoken) occurred, and scores the tourist's emotions and feelings by referring to dictionary information in which each word is recorded. Each word is linked to a score (posi-negative score) indicating the degree of positive and negative based on the meaning of the word. The dictionary information is not particularly limited and may be stored in memory 102 and storage device 104 in advance, or may be obtained from an external source by acquisition unit 11. The dictionary information may, for example, contain words specific to travel and tourism. The interest estimation unit 13 then identifies, for example, an event during the virtual trip corresponding to the time the transmission (spoken) occurred, and estimates the level of interest for each event by associating the event with the tourist's emotion and feelings score. This makes it possible to estimate, for example, what kind of spots, backgrounds, guide explanations, etc., the tourist was interested in.

[0047] Let's take a hypothetical trip introducing Shibuya's scramble crossing as an example to illustrate an example of how the interest estimation unit 13 estimates interest levels. Suppose a tourist participating in the hypothetical trip asks, for example, "Why are people walking so neatly without bumping into each other, even though so many people are crossing paths?" In this case, the interest estimation unit 13 estimates that the tourist is interested in "people walking neatly at Shibuya's scramble crossing" (i.e., has a high level of interest). Furthermore, if, at the time the tourist asks the question, the gaze of other tourists on the screen converges on the intersection and shows a significant positive shift (for example, smiling or showing a surprised expression), the interest estimation unit 13 estimates that these other tourists are also interested in "people walking neatly at Shibuya's scramble crossing" (i.e., have a high level of interest).

[0048] Furthermore, the interest level estimation unit 13 may, for example, estimate the level of interest for each tourist attribute (also called a customer segment) based on the level of interest for each tourist. In this case, the acquisition unit 11 may, for example, acquire the attributes of the tourists. Examples of such attributes include gender, age, address, family structure, occupation, etc. This makes it possible to understand, for example, the relationship between the tourist's attributes and their level of interest.

[0049] [Embodiment 3] Figure 4 is a block diagram showing the configuration of an example of the advertising information generation device 20 of this embodiment. As shown in Figure 4, the device 20 includes an acquisition unit 21, an analysis unit 22, an interest level estimation unit 23, and an advertising information generation unit 24. The acquisition unit 21, the analysis unit 22, and the interest level estimation unit 23 are the same as the acquisition unit 11, the analysis unit 12, and the interest level estimation unit 13 described in Embodiments 1 and 2, and the above description can be applied. In other words, the device 20 includes the parts of the interest level estimation device 10.

[0050] The device 20 may be, for example, a single device including the aforementioned parts, or it may be a device in which each of the aforementioned parts can be connected via a communication network. Furthermore, the device 20 can be connected to the aforementioned external device via the communication network. The communication network is not particularly limited and may be, for example, the same as described above. The device 20 may also be, for example, a personal computer (PC, e.g., desktop or notebook type), smartphone, tablet terminal, etc., on which the program of the present invention is installed. Moreover, the device 20 may be in the form of cloud computing or edge computing, for example, in which at least one of the aforementioned parts is on a server and the other parts are on a terminal.

[0051] Figure 5 shows an example block diagram of the hardware configuration of the device 20. The device 20 includes, for example, a central processing unit (CPU, GPU, etc.) 101, memory 102, bus 103, storage device 104, input device 105, output device 106, communication device 107, etc. Each part of the device 20 is interconnected via the bus 103 through its respective interface (I / F). Unless otherwise specified, the description of each part can be based on the description of the hardware configuration of the interest estimation device 10 shown in Figure 2. Note that these are examples, and the hardware configuration of the device 20 is not limited to this, as long as each part can perform the processing. Also, the number of central processing units 101 etc. included in the device 20 is not limited to the example in Figure 5; for example, multiple central processing units 101 may be included in the device 20.

[0052] The central processing unit 101 functions, for example, as an acquisition unit 21, an analysis unit 22, an interest level estimation unit 23, and an advertising information generation unit 24.

[0053] Next, an example of the advertising information generation method of this embodiment will be described based on the flowchart in Figure 6. The advertising information generation method of this embodiment is carried out as follows, for example, using the advertising information generation device 20 in Figure 4. Note that the advertising information generation method of this embodiment is not limited to the use of the advertising information generation device 20 in Figure 4.

[0054] In the advertising information generation method of this embodiment, the process performed by the acquisition unit 21 is the acquisition process, the process performed by the analysis unit 22 is the analysis process, the process performed by the interest level estimation unit 23 is the interest level estimation process, and the process performed by the advertising information generation unit 24 is the advertising information generation process.

[0055] In Figure 6, the acquisition of videos and questionnaire responses by the acquisition unit 21 (acquisition step (S21)), the generation of reaction information by the analysis unit 22 (analysis step (S22)), and the estimation of interest by the interest level estimation unit 23 (interest level estimation step (S23)) are the same as steps (S11) to (S13) shown in Figure 3, and the above description can be applied.

[0056] Then, after the above step (S23), the advertising information generation unit 24 generates advertising information related to the advertising of the actual trip based on the interest level (S24), and the process ends (END). Specifically, the advertising information generation unit 24 may, for example, generate advertising information including information about the tourist who has the interest level when the interest level satisfies a predetermined condition. The advertising information including information about the tourist is also referred to as, for example, a customer list. In other words, it can be said that the tourist is registered in the customer list. The customer list may be a list of people registered as targets for advertising an actual trip, or a list of people registered as targets for advertising a virtual trip. The predetermined condition is not particularly limited and can be set arbitrarily, for example, whether the value of the interest level is above a predetermined threshold, or whether the interest level is information indicating interest such as "interested". The threshold can also be set arbitrarily.

[0057] According to this embodiment, it is possible to estimate the degree of interest in real-world travel among tourists participating in virtual travel. Furthermore, by generating the aforementioned promotional information, it is possible to efficiently promote real-world travel.

[0058] [Embodiment 4] An example of how the advertising information generation unit 24 generates advertising information will be described in detail. Note that these are examples, and the generation of advertising information by the advertising information generation unit 24 is not limited to the content of this embodiment.

[0059] Specifically, an example of how the advertising information generation unit 24 generates advertising information will be explained using a virtual trip introducing Shibuya's scramble crossing as an example. The interest level estimation unit 23 estimates, similar to the description in Embodiment 2, that the tourist who asked the question is interested in (i.e., has a high level of interest in) "people who walk neatly at Shibuya's scramble crossing." The interest level estimation unit 23 also estimates, similar to the description in Embodiment 2, that the other tourists are interested in (i.e., have a high level of interest in) "people who walk neatly at Shibuya's scramble crossing." Next, the advertising information generation unit 24 aggregates the interest levels of multiple tourists, for example, and identifies the time period with the highest level of interest in the virtual trip. The aggregation method is not particularly limited, and for example, a total value, an average value, etc., may be calculated. Then, the advertising information generation unit 24 extracts video footage corresponding to the time period from the virtual trip video as advertising information. The video footage of the advertising information is used, for example, as a promotional video on the virtual trip sales site.

[0060] Furthermore, the advertising information generation unit 24 may generate a customer list as advertising information for each tourist, for example, by linking the application information such as the email address used when the tourist applied to participate in the virtual trip with the level of interest. In addition, the customer list may be further linked with the responses to the questionnaire. This allows the provider of the virtual trip to understand, for example, what kind of tours and spots the tourist is interested in and to what extent, and the tourist's values ​​regarding tours (virtual trips and real tours; the same applies hereinafter). Also, if the interest level estimation unit 23 estimates the level of interest for each attribute of the tourist (also called a customer segment), the advertising information generation unit 24 can, for example, segment the target customers.

[0061] Furthermore, the advertising information generation unit 24 may, for example, estimate the value the tourists have of the tour based on their responses to the questionnaire and their level of interest, and then set the price of the tour as advertising information based on those values.

[0062] [Embodiment 5] The program of this embodiment is a program that causes a computer to execute each step of the method of the present invention as a procedure. In the present invention, "procedure" may be read as "process". The program of this embodiment may also be recorded on a computer-readable recording medium, for example. The recording medium is, for example, a non-transitory computer-readable storage medium. The recording medium is not particularly limited and includes, for example, read-only memory (ROM), hard disk (HD), optical disc, etc.

[0063] Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above embodiments. Various modifications to the configuration and details of the present invention can be understood by those skilled in the art within the scope of the present invention.
