Description

Exhibition support system, questionnaire processing method, service processing method, and effect presentation processing method for exhibition support system

[0001] The present invention relates to an exhibition support system, a questionnaire processing method, a service processing method, and an effect presentation processing method for an exhibition support system.

[0002] In Japan, various exhibitions held in real space are often held in major cities, for example, at Tokyo Big Sight (registered trademark) and other venues.

[0003] For this reason, when a person residing in a rural area is interested in the exhibition, it is necessary for the person to travel to Tokyo by some means of transportation, then transfer between trains and buses to arrive at the destination, go through gate procedures, and complete the check-in process to enter the main exhibition hall.

[0004] As a system that reduces the burden on such distant visitors and allows them to easily browse the exhibition venue while staying in their local area, opportunities to use virtual exhibition systems and the like are increasing, and various virtual exhibition systems have been developed in response to the demands for convenience, profitability, and business negotiation performance (such as contract conclusion performance) from organizers, exhibitors, and on-site visitors.

[0005] The following Patent Document 1 discloses that "In order to improve the presentation effect and convenience of a virtual space system, the virtual space system 1 includes a server 21 provided by an operating organization that operates the exhibition, a plurality of exhibitor-side information terminals 31-1, 31-2... 31-m that respectively set up a plurality of booths for the exhibition using the virtual space, and visitor-side information terminals 4-1, 4-2... 4-n used by visitors attending the exhibition. When a visitor performs an attendance operation on the visitor-side information terminals 4-1, 4-2... 4-n, the server 21 performs control to display a plurality of selection areas respectively corresponding to the plurality of booths on the visitor-side information terminals 4-1, 4-2... 4-n. When a visitor performs an operation of selecting one selection area from the plurality of selection areas on the visitor-side information terminals 4-1, 4-2... 4-n, the server 21 performs control to move the display to the booth corresponding to the selected selection area on the visitor-side information terminals 4-1, 4-2... 4-n."

[0006] Furthermore, Patent Document 2 discloses that, "In order to reduce the costs and effort involved in holding an exhibition and to make it easier to hold an exhibition, the organizer's terminal sends data of the virtual exhibition venue to be rented, data of the exhibits to be exhibited, and order data, which is the rental conditions such as the rental period, to a virtual exhibition venue reception terminal via the network. The virtual exhibition venue reception terminal receives this data and generates contract data such as the rental fee, and once confirmed, sends exhibition specification data, which includes three-dimensional image data (exhibition venue data and exhibit data), to a virtual space provision terminal. When the date and time of the exhibition arrive, the exhibition specification data on the virtual space provision terminal becomes accessible. Viewers access the virtual space provision terminal from their viewing terminals via the network and view the exhibition in the three-dimensional virtual space. When the rental period expires, the exhibition specification data automatically becomes inaccessible."

[0007] Furthermore, Patent Document 3 discloses "a user-participatory internet site guidance system 100 that aims to provide an internet site guidance system that can promote user browsing, comprising a user terminal 1 equipped with a web browser 1a, an event participation site server 20, and a net event host site computer 10, wherein the net event host computer 10 comprises a web server 11, an application server 12, a database server 13, and an administrator terminal 16, and when a user accesses the net event gate page of the net host computer 10, a time-series changing guidance screen is sent to the user terminal, and the information displayed on the time-series changing guidance screen induces the user to search for event participation sites where time-series changing display information is displayed, thereby promoting browsing of event participation sites."

[0008] Japanese Patent Publication No. 2022-089597, Japanese Patent Publication No. 2002-342673, Japanese Patent Publication No. 2003-108465

[0009] Patent Document 3, mentioned above, describes how, in exhibitions and the like in a virtual space, a questionnaire can be prepared in advance so that visitors can point out useful reactions and points for consideration to exhibitors, and the responses from visitors to the questionnaire can be directly fed back to the exhibitors and organizers.

[0010] However, because the questionnaires are created in a uniform manner, they often do not reflect the exhibitors' desire to obtain in-depth responses. As a result, the probability of the feedback from the questionnaires being adopted and reflected in the next exhibition is low. It has also been pointed out that the questionnaires do not adequately function as useful resources for exhibitors, organizers, and visitors who wish to improve them, such as by addressing linguistic elements including the expression, format, and readability of the questionnaire text.

[0011] In particular, there was a challenge in presenting questionnaires with appropriate timing and content in line with visitors' movement patterns, and in failing to obtain responses that encompassed a wide range of factors, such as trendiness, foresight, and market potential for product development.

[0012] The first invention was made to solve the above problems, and aims to provide an exhibition support system and a method for processing questionnaires for an exhibition support system that can identify visitors who can be guided to business negotiations as much as possible by prompting them to complete questionnaires at the optimal timing adapted to the viewing status, movement range, and movement trajectory of visitors who have made reservations to attend a virtual exhibition or virtual showroom business, which mutually links virtual space and real space and has excellent operability.

[0013] The second invention was made to solve the above problems, and aims to provide an exhibition support system and service processing method for an exhibition support system that offers excellent operability, allowing visitors to freely and clearly view explanations of the items displayed in the virtual exhibition booths, simply by selecting the booth they want to move to and moving to the exhibition booths displayed within the virtual exhibition booth, in conjunction with large panel displays, as a way to present the virtual exhibition.

[0014] The third invention was made to solve the above problems, and aims to provide an exhibition support system and a method for processing the presentation of an exhibition support system that allows visitors to a virtual exhibition or virtual showroom to view highly realistic exhibition information that cannot be reproduced in a virtual exhibition or virtual showroom by reproducing the exhibition information of a real showroom using a digital twin.

[0015] The exhibition support system that achieves the above objectives has the following configuration.

[0016] The first invention of the present invention is an exhibition support system that enables communication between a server device that provides a service of providing a virtual showroom built on the cloud via a predetermined communication medium, a first data terminal operated by a visitor to the virtual showroom, a second data terminal operated by a participant in the virtual showroom, and a third data terminal operated by the organizer presenting the virtual showroom, wherein the server device includes a questionnaire screen display means that displays a questionnaire screen prompting the visitor to respond to a questionnaire based on the movement status of an attendant to each exhibition booth displayed in the virtual showroom or the amount of text spoken about each exhibition booth, in accordance with instructions from the first data terminal, and an indexing means that analyzes the response content input from the first data terminal to the questionnaire screen displayed by the questionnaire screen display means, calculates evaluation values ​​for the visitor and the exhibitor, and indexes them.

[0017] The second invention of the present invention is an exhibition support system that enables communication between a server device that provides a service of providing a virtual space constructed on the cloud via a predetermined communication medium and a data terminal operated by a visitor visiting the virtual space, wherein the server device includes a generation means that causes an attendant to appear that can move freely within the virtual space upon receiving panel instructions displayed in the virtual space from the visitor via the data terminal, and an attendant control means that controls the actions of the attendant within the virtual space and the tone of the narration performed by the attendant based on panel operation instructions displayed in the virtual space, wherein the attendant control means initiates an operation to move the attendant walking to a spatial position set in the virtual space based on the panel operation instructions.

[0018] The third invention in the present invention is an exhibition support system that enables communication between a server device that provides a service of providing a virtual showroom built on the cloud via a predetermined communication medium, a first data terminal operated by a visitor to the virtual showroom, a second data terminal operated by an exhibitor exhibiting in the virtual showroom, and a third data terminal operated by an organizer presenting the virtual showroom, wherein the server device comprises a digital twin generation means that acquires 3D image information corresponding to a real exhibition booth captured by the exhibitor on the third data terminal and generates a digital twin of each of the exhibition booths, and a real exhibition booth display means that displays the digital twin generated by the digital twin generation means within the virtual exhibition booth.

[0019] According to the first invention, virtual exhibitions and virtual showroom businesses can connect virtual and real spaces in an easily usable way. By sending questionnaires at the optimal timing, adapted to the viewing status, movement range, and movement trajectory of visitors who have made reservations, it is possible to identify visitors who can be guided into business negotiations as much as possible.

[0020] According to the second invention, explanations of items displayed in the virtual space are linked with large panel displays, allowing visitors to focus on the attendant's explanations and easily and clearly understand the exhibits. This enables visitors staying in the virtual space to share the sense of presence as if they were at a real exhibition or showroom.

[0021] According to the third invention, explanations of items displayed in a virtual exhibition booth are linked with large panel displays, allowing viewers to clearly understand the exhibits by focusing on the attendant's explanations.

[0023] Next, the best mode for carrying out the present invention will be described with reference to the drawings.

[0024] <System Configuration Description> [First Embodiment] Figure 1 is a block diagram illustrating the configuration of the exhibition support system shown in this embodiment. This example is an exhibition support system that enables communication between a server device 1 that provides a service of providing a virtual space built on the cloud via a predetermined communication medium, first data terminals 3-1 to 3-N and second data terminals 4-1 to 4-N operated by visitors to the virtual space, third data terminals 5-1 to 5-N operated by exhibitors who exhibit in the virtual space, and fourth data terminals 2-1 to 2-N operated by the organizer who opens the virtual space and deploys video services.

[0025] Furthermore, the server device 1 is configured to provide virtual space services and real space services to the first to fourth data terminals 3-1 to 3-N, 4-1 to 4-N, and 5-1 to 5-N, and 2-1 to 2-N, as described later, via platform 1A. This configuration allows for the mutual and dynamic switching and control of virtual showrooms, virtual exhibitions, real showrooms, and real exhibitions on a single system on the cloud (a specific URL), thereby enabling the provision of services that can be freely viewed using both virtual and real spaces.

[0026] Furthermore, this system uses publicly accessible virtual showrooms and virtual exhibitions as examples of virtual spaces, as well as publicly accessible real showrooms and real exhibitions.

[0027] [Server Device 1] Figure 2 is a block diagram illustrating the configuration of server device 1 shown in Figure 1, and components identical to those in Figure 1 are denoted by the same reference numerals.

[0028] In Figure 2, 11 is the communication unit, which connects the server device 1 with the first data terminals 3-1 to 3-N, the second data terminals 4-1 to 4-N, the third data terminals 5-1 to 5-N, and the fourth data terminals 2-1 to 2-N, which are connected to the network 21 as a communication medium, and controls communication.

[0029] 13 is the CPU, which starts the operating system (OS) stored in the external memory 18 connected to the internal bus 12 and launches various applications. The CPU 13 also executes the processing of various programs loaded on the RAM 16.

[0030] 15 is the keyboard, used for numerical input, text input, and icon selection for running applications.

[0031] 16 is a RAM with expandable capacity that stores the basic program for disclosing platform 1A installed in external memory 18. 17 is a display that shows the program's startup status via various UI screens (not shown).

[0032] The basic program in this embodiment includes a generation unit 16-1 that generates an attendant who can move freely within the virtual space in response to panel instructions displayed on the virtual space accessible on platform 1A from the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N when visitors receive these instructions, and an attendant control unit 16-2 that controls the attendant's actions and mannerisms within the virtual space and the tone of the narration performed by the attendant (pitch of vocal frequency, speaking speed, speaking rhythm, intonation, etc.) based on panel operation instructions displayed in the virtual space. The attendant control unit 16-2 is configured to initiate an action that causes the attendant to walk to a spatial position set in the virtual space based on the panel operation instructions. Furthermore, the display control unit 16-3 is configured to control the switching of spatial display modes so that different spaces are displayed as real space or other virtual spaces (assuming multiple virtual spaces are managed).

[0033] Here, the CPU 13 is configured to activate the generation unit 16-1 and the attendant control unit 16-2, which are deployed in the RAM 16, at appropriately set timings, and to guide visitors from the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N connected to the platform 1A to the virtual showroom and virtual exhibition, and to have attendants narrate about the items (including tangible objects and programs as software) displayed in the virtual showroom and virtual exhibition, thereby controlling the promotion of new products and the guidance of business negotiations.

[0034] In this case, the attendant control unit 16-2 is configured to comprehensively control the difficulty level, explanation speed, and language of the narration content based on the registration information of the visitors.

[0035] Similarly, the attendant control unit 16-2 is configured to comprehensively control the attendant's actions, including facial expressions, appearance, and hand gestures, based on responses from the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N.

[0036] Furthermore, the attendant control unit 16-2 is configured to control the attendant's narration service in response to multiple visitors.

[0037] Similarly, the attendant control unit 16-2, upon receiving notification that the attendant has started moving from a predetermined explanation start position and moved to a predetermined waiting position, is configured to cause the attendant to give an explanation guiding the user to move to a space different from the virtual space in which they were staying at the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N.

[0038] Furthermore, the attendant control unit 16-2 is configured to freely switch and control the appearance, demeanor, and attire of the attendants based on the responses to the items queried when the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N register as visitors.

[0039] [Configuration of the First to Fourth Data Terminals] Figure 3 is a block diagram illustrating the configuration of the first data terminals 3-1 to 3-N, the second data terminals 4-1 to 4-N, the third data terminals 5-1 to 5-N, and the fourth data terminals 2-1 to 2-N shown in Figure 1. Note that the second data terminals 4-1 to 4-N, the third data terminals 5-1 to 5-N, and the fourth data terminals 2-1 to 2-N are assumed to be devices such as tablet devices, PC devices, and smartphones.

[0040] In Figure 3(a), 301 is the CPU, which loads the OS and control programs stored in ROM 302 into RAM 303 and executes them to run various applications. Inputting various information and clicking icons displayed on the user interface screen (UI screen) are performed directly on the display 311 by operating the keyboard 310 or a pointing device (not shown). 304 is the communication unit, which controls communication for connecting to the server device 1 connected to the network 21.

[0041] In the RAM 303 shown in Figure 3(b), 303-1 is the login unit, which processes connection requests to platform 1A via the network 21. 303-2 is the upload / download unit, which executes the process of obtaining applications provided by server device 1.

[0042] Furthermore, the CPU 301 manages account information (user ID, password) registered by a user on the platform 1A publicly disclosed on the WEB by the server device 1 using an external storage device such as an unillustrated SSD.

[0043] 303-3 is a UI control unit, which executes control to display a UI screen presented from the platform 1A provided by the server device 1 shown in FIG. 1 on the display 311.

[0044] [Overview of Virtual Space] FIGS. 4 to 6 are drawing diagrams showing operation examples of the virtual space displayed on the display 311 of the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N shown in FIG. 1.

[0045] The virtual space panel display shown in FIG. 4 is a virtual space panel display that is first displayed after the attendance processing is completed, when a visitor operating the first data terminals 3-1 to 3-N has logged into the virtual space specified by a specific URL by selecting either a free attendance reservation mode or a reserved attendance reservation mode described later. That is, when the reservation processing has been completed normally, a reserved visitor can visually recognize the content described on the exhibition panel shown in FIG. 4 to confirm the overview of the current exhibition, the venue, the exhibition period, and that exhibited products (No. 1 to No. 6) are being displayed.

[0046] Furthermore, it is assumed that the appearance position of an attendant is configured to be controllable according to the panel size and the panel drawing position.

[0047] As described above, the appearance and the like of an attendant are configured such that the appearance, hair style, clothing, hairstyle, facial expression (whether it is gentle or not), actions and the like can be freely adjusted based on questionnaire responses and the requirements of the organizer and exhibitor.

[0048] Next, any exhibition booth can be selected by a visitor pointing with the pointing device of the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N operated by the visitor to the numerical buttons (display buttons on the virtual space) BT1 to BT6 of the exhibited products (No. 1 to No. 6) displayed on the panel.

[0049] In response to this, the CPU 13 of the server device 1 shown in Fig. 1 activates the attendant control unit 16-2, thereby controlling the operation of the attendant to automatically start moving to the position where the instructed exhibited product is drawn according to the layout information arranged in the virtual space. At this time, it is assumed that the moving speed of the attendant is configured to be freely adjustable by settings from the fourth data terminals 2-1 to 2-N operated by the organizer.

[0050] Hereinafter, description will be given on the assumption that visitors using the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N have instructed to press the numerical button BT2 corresponding to "2" among the numerical buttons functioning as exhibition hall selection buttons shown in Fig. 5, for example.

[0051] In addition, the attendant uses a panel showing an overview of the exhibition as a background and starts narration for explaining the panel. At this time, the fact that narration is being performed is displayed together with an audio output icon. In the present embodiment, a marker is displayed so as to connect the upper end and the left end of the panel.

[0052] It should be noted that the server device 1 is configured to be freely adjustable by finely setting the speed and tone of narration based on the parameters (male, female, anime voice, multi-language support) of the attendant personality setting table set by the visitor.

[0053] Figs. 7 and 8 are conceptual diagrams visualizing an example in which an attendant narrates the content while disclosing an installation example proposed by an exhibitor (a booth designer in this example) using the exhibition booth shown in Fig. 6, wherein Fig. 7 corresponds to a list of woodworking booths, and Fig. 8 corresponds to a list of system booths.

[0054] In this example, the exhibition panel screen shows a case where grouped screens (still screens of a real exhibition booth) grouped in response to the exhibitor's request are displayed as a digest.

[0055] Figures 9 to 11 are flowcharts showing the first data processing procedure in the exhibition support system according to this embodiment. This procedure corresponds to the display control procedure by the display control unit 16-3 of the server device 1 shown in Figure 1. (1) to (25) indicate each step, and each step is realized by the CPU 13 executing a program and the display control unit 16-3 executing a program.

[0056] First, if the CPU 13 determines that a visitor who has connected to platform 1A by operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is a person with a reservation (1), the CPU 13 reads the reservation information made by the person with a reservation from the external memory 18 (2).

[0057] Next, the CPU 13 activates the generation unit 16-1 and presents a virtual space based on the reservation information read on the browsers of the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (3). Next, the CPU 13 activates the attendant control unit 16-2 and makes the attendants appear at the spatial coordinates set on the virtual exhibition to be held (4).

[0058] At that time, the CPU 13 determines whether the spatial coordinates (appearance position) where the attendant appeared are the home position (5). If it determines that it is not the home position, the CPU 13 activates the display control unit 16-3 to adjust the drawing position (spatial coordinate value) of the attendant (7), and proceeds to step (8).

[0059] On the other hand, in step (5), if the CPU 13 determines that the spatial coordinates (appearance position) where the attendant appeared are the home position, the CPU 13 activates the display control unit 16-3 and displays the exhibition booth selection panel in the virtual space (6).

[0060] Next, the CPU 13 sets the booth selection number (in this embodiment, 1 to 6 is assumed) attached to the displayed exhibition booth selection panel to N (8). At this point, the CPU 13 determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has selected "1" as the booth selection number N by operating the pointing device (9). If the CPU 13 determines that "1" has been selected as the booth selection number N, it sets the display control unit 16-3 to mode 1, which indicates that the attendant is moving in the virtual space (10), and proceeds to step (21).

[0061] Meanwhile, in step (9), the CPU 13 determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has selected "2" as the booth selection number N by operating the pointing device (11). If the CPU 13 determines that "2" has been selected as the booth selection number N, it sets the display control unit 16-3 to mode 2, which indicates the attendant moving around in the virtual space (16), and proceeds to step (21).

[0062] On the other hand, in step (11), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has not operated the pointing device to select "2" as booth selection number N, it determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has operated the pointing device to select "3" as booth selection number N (12). If the CPU 13 determines that "3" has been selected as booth selection number N, it sets the display control unit 16-3 to mode 3, which indicates that the attendant is moving around in the virtual space (17), and proceeds to step (21).

[0063] On the other hand, in step (12), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has not operated the pointing device to select "3" as booth selection number N, the CPU 13 determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has operated the pointing device to select "4" as booth selection number N (13). If the CPU 13 determines that "4" has been selected as booth selection number N, it sets the display control unit 16-3 to mode 4, which indicates the attendant moving in the virtual space (18), and proceeds to step (21).

[0064] On the other hand, in step (13), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has not operated the pointing device to select "4" as booth selection number N, it determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has operated the pointing device to select "5" as booth selection number N (14). If the CPU 13 determines that "5" has been selected as booth selection number N, it sets the display control unit 16-3 to mode 5, which indicates the attendant moving in the virtual space (19), and proceeds to step (21).

[0065] Meanwhile, in step (14), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has not operated the pointing device to select "5" as booth selection number N, the CPU 13 determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has operated the pointing device to select "N (=6)" as booth selection number N (15). If the CPU 13 determines that "6" has been selected as booth selection number N, it sets the display control unit 16-3 to mode 6, which indicates the attendant's movement in the virtual space (20), and proceeds to step (21). In this state, the attendant is moving (walking) to the exhibition booth that matches the number selected by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N. If, in step (15), the CPU 13 determines that it has not selected "6" as the booth selection number N, the process returns to step (8).

[0066] Next, the CPU 13 activates the attendant control unit 16-2 to adjust the voice-over status of the narration set for each exhibition booth (21). This allows the attendant to adjust the difficulty level of the explanation according to the visitor's gender and age, and to explain the products, goods, services, etc. to the visitor in a friendly and courteous manner.

[0067] Next, the CPU 13 determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is moving the attendant's spatial coordinates to a pre-set HOT point (multiple points can be set) in the virtual space (22). If the CPU 13 determines that the virtual space coordinates where the attendant is currently drawn are staying at a HOT point (a predetermined time elapsed is counted), the CPU 13 further determines whether it is appropriate to switch the drawing mode in the virtual space from virtual to real (23). If the CPU 13 determines that it is not appropriate to switch the drawing mode in the virtual space from virtual to real, it determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has given an instruction to exit the virtual space (25). If the CPU 13 determines that the visitor has given an instruction to exit, it terminates this process.

[0068] On the other hand, if in step (25) the CPU 13 determines that it has not issued an instruction to exit, it returns to step (5).

[0069] On the other hand, in step (23), if the CPU 13 determines that it is appropriate to switch the rendering mode in the virtual space from virtual to real, it activates the display control unit 16-3 to switch the rendering mode of the platform 1A to real rendering (24), and proceeds to step (25).

[0070] This allows visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N to be guided to view the exhibitors' real showrooms, which are not visible in the virtual space, on their browsers without requiring them to perform any screen switching operations.

[0071] [Effects of the First Embodiment] According to this embodiment, by focusing on the attendant's explanation of the items displayed in the virtual space in conjunction with a large panel display, users can easily and enjoyably view the exhibits while clearly understanding the explanations of the exhibits, thereby sharing a sense of presence as if they were at a real exhibition or showroom.

[0072] In this embodiment, we have described virtual space display control mainly involving an attendant narrating to visitors. However, assuming that visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N are equipped with voice response devices (microphones and speakers), the AI ​​support unit 19 may adapt to prompts transcribed into text via a large-scale language model (LLM) to implement a question-and-answer function (incorporating the function processing procedure into the flowchart shown in Figure 9) that allows visitors to listen to more in-depth explanations of the generated product descriptions or view a list of similar products.

[0073] [Second Embodiment] In the above embodiment, the functional processing of attendants in a virtual exhibition booth was described, but a system that utilizes virtual space may also include a configuration that supports a service that provides a virtual showroom in addition to a virtual exhibition booth.

[0074] Figure 12 is a block diagram illustrating the configuration of the exhibition support system shown in this embodiment. Components identical to those in Figure 2 are given the same reference numerals and their descriptions are omitted.

[0075] The display control unit 16-3 in the server device 1 shown in Figure 12 has a configuration that allows the CPU 13 to reversibly switch from virtual space to physical space for visitors operating the first data terminals 3-1 to 3-N and visitors operating the second data terminals 4-1 to 4-N.

[0076] Figure 13 is a diagram showing how the exhibition support system in this embodiment is used. In this embodiment, an example of an exhibition support system is provided in which a server device 1 that provides a service of a virtual showroom built on the cloud is able to communicate with first data terminals 3-1 to 3-N and second data terminals 4-1 to 4-N operated by visitors to the virtual showroom, and third data terminals 5-1 to 5-N operated by exhibitors who display goods etc. in the virtual showroom.

[0077] In Figure 13, a system may be configured to meet the needs of exhibitors by linking a first mode in which a virtual showroom (intended to be permanently installed in the virtual space) that is made public as a virtual space and a virtual exhibition booth (intended to be installed in the virtual showroom when exhibiting at an exhibition) are linked, and a second mode in which a real showroom (real space) that is made public as a physical space and a real exhibition booth are linked together.

[0078] As a result, in the virtual exhibition screen shown as an example in Figure 14, the attendant displayed in the virtual showroom can reversibly receive requests from visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N to transfer from the display state of any virtual booth to the display state of a real booth provided by the organizer and associated with that virtual booth. In response, the display control unit 16-3 can reversibly control the switching from the display state of a virtual booth to the display state of a real booth, or from the display state of a real booth to the display state of a virtual booth.

[0079] In this case, the display control unit 16-3 is configured to also perform summarized video playback according to the video playback history when playing video information of the actual booth to be played. This makes it possible to quickly view popular videos that visitors who have already visited have shown interest in.

[0080] Similarly, the design unit 16-4 shown in Figure 12 executes functional processing to design the layout of each virtual booth to be displayed in the virtual showroom by acquiring booth designs and exhibition materials to be displayed from the third data terminals 5-1 to 5-N.

[0081] Furthermore, the parts data necessary for booth design is stored in external memory 18, and when the CPU 13 starts the design unit 16-4, it can utilize variations of booth design parts that meet the exhibitor's requirements.

[0082] Furthermore, the generation unit 16-5 shown in Figure 12 performs a functional process to generate a design that is embellished from pre-set decorating data, with shape, hue, and size determined from the third data terminals 5-1 to 5-N, so that the display manner of the fixtures to be placed in each exhibition booth has a consistent look and feel.

[0083] Similarly, the generation unit 16-5 shown in Figure 12 summarizes the listing information obtained from the third data terminals 5-1 to 5-N and performs functional processing to automatically generate the display order and content of the listing information.

[0084] Similarly, the generation unit 16-5 shown in Figure 12 performs functional processing to readjust the display order of the acquired exhibit information and the content of the exhibit information, according to the priority order that the AI ​​has summarized from the questionnaire responses of visitors from the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N to each exhibit booth.

[0085] On the other hand, the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N, which communicate with the server device 1 shown in Figure 2, may be configured to include a viewpoint indicator unit that instructs the server device 1 on the viewing position of items displayed in the real booth according to the 3D viewpoint coordinates indicated by the visitor, thereby allowing visitors to view drawn images of the real booth (including real showrooms and real exhibition booths) adapted to their viewpoint.

[0086] Furthermore, the server device 1 shown in Figure 12 is equipped with an intermediary unit 16-6 that mediates voice responses between visitors and the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N for items exhibited in the physical booth, and it is also possible to configure the system as one that integrates visual and auditory elements by setting up a voice response environment.

[0087] This significantly improves visitors' understanding of explanations received from attendants, making it possible to clearly communicate the exhibitor's intentions.

[0088] Furthermore, as shown in Figure 12, the server device 1 may be configured to include a first determination unit 16-7 that determines whether the logo information used by visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is similar to the color tone of the exhibition booth, a second determination unit 16-8 that determines whether the color tone of the exhibition booth is similar, and a logo display control unit 16-9 that automatically adjusts the brightness and contrast of the logo information so that the visual recognition of the logo information is clear when it is determined that the color tone of the exhibition booth is similar to the logo information. This prevents visitors from overlooking trademarks and logos used by exhibitors in exhibition booths or showrooms where trademarks and logs are designed.

[0089] [Effects of the Second Embodiment] According to this embodiment, when a showroom and exhibition booths are made public on platform 1A, it is possible to switch between mutual public access and separate public access between a virtual mode exhibition using a virtual space and a real mode exhibition using a physical space, on a single system, according to the needs of visitors and exhibitors.

[0090] [Third Embodiment] In the above embodiment, visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N are required to make some kind of advance reservation for some kind of virtual exhibition. However, in normal systems, visitors are assumed to enter on a free-entry basis, so the convenience and scalability of the reservation system are often not flexible.

[0091] Therefore, the server device 1 may be configured to have a reservation management function that integrates visitor reservation processing for both virtual and real exhibitions, thereby improving visitor convenience by linking visitor reservation processing between real and virtual exhibitions, or between real and virtual showrooms, in accordance with the visitor's needs.

[0092] Figures 15 to 17 show the configuration of the reservation function processing of the exhibition support system in this embodiment. In this example, promotional activities may be included to ensure that visitors who are likely to become HOT leads participate in virtual space events or real-world events.

[0093] Furthermore, in this embodiment, an example of an exhibition support system is provided, which includes a server device 1 that provides a service of presenting a virtual showroom built on the cloud via a predetermined communication medium, a first data terminal 3-1 to 3-N and a second data terminal 4-1 to 4-N operated by visitors to the virtual showroom or virtual exhibition, and a third data terminal 5-1 to 5-N operated by an exhibitor participating in the virtual showroom or virtual exhibition as a host, and which can communicate with each other.

[0094] Figure 18 is a block diagram illustrating the configuration of the exhibition support system shown in this embodiment. The same reference numerals are used for the same components as in Figure 2, and their descriptions are omitted.

[0095] In the server device 1 shown in Figure 18, 16-71 is a first reservation screen display unit that performs the process of displaying to the first data terminals 3-1 to 3-N a first reservation screen for visiting a virtual showroom or virtual exhibition, or a second reservation screen for visiting a real showroom or real exhibition.

[0096] 16-72 is the first reservation registration unit, which, in response to visitors operating the first data terminals 3-1 to 3-N entering visitor information on the first reservation screen or the second reservation screen, executes a first reservation registration process that links the first visit reservation to the virtual showroom or virtual exhibition with the second visit reservation to the real showroom or real exhibition in a reservation management table (reserved in external memory 18).

[0097] 16-73 is a second reservation screen presentation unit that performs a second reservation screen presentation process to present a third reservation screen for visiting a virtual showroom or a real showroom, or a fourth reservation screen for visiting a virtual exhibition or a real exhibition, to the first data terminals 3-1 to 3-N.

[0098] 16-74 is the second reservation registration unit, which, in response to visitors operating the first data terminals 3-1 to 3-N entering visitor information on the third reservation screen or the fourth reservation screen, executes a second reservation registration process that links the third visit reservation for the virtual showroom or real showroom with the fourth visit reservation for the virtual exhibition or the said real exhibition into a reservation management table.

[0099] 16-75 is a third reservation screen presentation unit that, when a visitor operating the first data terminals 3-1 to 3-N visits a virtual showroom selected by the visitor, performs a third reservation screen presentation process to the first data terminals 3-1 to 3-N, allowing the visitor to select one of the first to fourth reservation screens of their choice.

[0100] 16-76 is a guidance control unit that determines the participation pattern of a visitor operating the first data terminals 3-1 to 3-N and performs guidance control to switch and control the guidance procedure to the first to fourth reservation screens desired by the visitor.

[0101] Here, the guidance control unit 16-76 has a determination function that compares the location information of the visitor operating the first data terminals 3-1 to 3-N with the location information of the real showroom or real exhibition to determine whether or not it is possible to visit in person. If it determines that it is not possible to visit in person, it executes a process to guide the visitor operating the first data terminal to a reservation screen that prompts them to make a reservation to visit the virtual exhibition or virtual showroom.

[0102] Furthermore, the guidance control unit 16-76 has a determination function that compares the location information of the visitor operating the first data terminals 3-1 to 3-N with the location information of the real showroom or real exhibition to determine whether or not it is possible to visit directly. If it determines that it is possible to visit directly, it executes a process to guide the visitor operating the first data terminals 3-1 to 3-N to a reservation screen that prompts them to make a reservation to visit the real exhibition or real showroom.

[0103] In Figure 15, in Stage ST1, search engine optimization (SEO), online advertising, and offline advertising are implemented to ensure that search engines find the content. Next, in Stage ST2, users who have shown interest in Stage ST1 (those who are not yet confirmed as visitors) are guided to the company's website (virtual showroom).

[0104] Next, in Stage ST3, we will send invitation emails to visitors from our company's website, hoping for free attendance.

[0105] Furthermore, Stage ST4-1 manages reservations for the virtual showroom or virtual exhibition via the reservation page described later, using Stage ST3.

[0106] Furthermore, Stage ST4-2 manages the reservations of viewers for real showrooms or exhibitions via the reservation page described later, using Stage ST3.

[0107] Server device 1 assigns points to each reservation holder based on specific response parameters (questionnaire analysis, brochure delivery request, business meeting request), and then sorts and manages visitors into those to be treated as HOT leads and those to be treated as other visitors based on their total points.

[0108] This allows sales representatives to contact, visit, or initiate sales activities such as Zoom meetings with attendees who have a high probability of closing a deal, at the appropriate time.

[0109] Figure 16 shows an example of a venue reservation type for the exhibition support system illustrating this embodiment, illustrating an example where reservation processing for exhibitions and showrooms is exclusively accepted.

[0110] Figure 17 shows an excerpt of the venue reservation screen of the exhibition support system illustrating this embodiment. For example, the virtual exhibition booth visitor reservation screen is configured with date cells arranged horizontally and time cells arranged vertically, allowing visitors to make their own selections.

[0111] Furthermore, to flexibly handle cancellations and date / time changes after booking, a specific password can be issued via email to the person who made the reservation, allowing for flexible addition, modification, and deletion of reservation dates and times. It is also possible to configure the narration control unit 16-31's function processing as a method.

[0112] [Effects of the Third Embodiment] According to this embodiment, regardless of whether the transport space instructed by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is between real spaces or between virtual spaces, the visitor can be guided to efficiently perform a series of reservation processes that link each space with simple operations.

[0113] [Fourth Embodiment] In the above embodiment, it was explained that a user who searches the company homepage of an exhibitor participating in a virtual exhibition is guided to the reservation process for the virtual exhibition. However, it is desirable for the system to be configured so that the information that visitors provide as feedback upon their arrival can be appropriately surveyed by the exhibitor to obtain reactions regarding new product development, changes in product design, and related product ideas and services.

[0114] Therefore, the server device 1 may be configured to incorporate a function that can automatically create and propose the core structure of the questionnaire intended by the exhibitor, the number of questionnaire items to obtain the desired responses, the expression style of the questionnaire text, the number of text items, etc.

[0115] [Questionnaire Processing] Figure 19 is a block diagram illustrating the configuration of the exhibition support system shown in this embodiment. This system is an example of an exhibition support system that enables communication between a server device 1 that provides a service of a virtual showroom built on the cloud via a predetermined communication medium, first data terminals 3-1 to 3-N and second data terminals 4-1 to 4-N operated by visitors to the virtual showroom, third data terminals 5-1 to 5-N operated by exhibitors exhibiting in the virtual showroom, and fourth data terminals 2-1 to 2-N operated by the organizer presenting the virtual showroom.

[0116] In the server device 1 shown in Figure 19, 16-21 is a questionnaire screen display unit that, in accordance with instructions from the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N, executes a process to display a questionnaire screen prompting visitors to respond to the questionnaire, based on the movement status of the attendant to each exhibition booth displayed in the virtual showroom or the amount of text spoken about each exhibition booth.

[0117] 16-22 analyzes the responses entered from the first data terminals 3-1 to 3-N to the questionnaire screen displayed by the indexing unit and questionnaire screen display unit 16-21, calculates evaluation values ​​for the organizers, visitors, and exhibitors, and performs the process of creating an index.

[0118] Sections 16-23 are generation units that perform the process of generating effective response messages for organizers, visitors, and exhibitors.

[0119] At that time, the sending unit 16-24 executes the process of sending a questionnaire report, which combines the response message generated by the generation unit 16-23 and the evaluation value indexed by the indexing unit 16-22, to the third data terminals 5-1 to 5-N and the fourth data terminals 2-1 to 2-N.

[0120] Here, it is assumed that the order, content, and length of the text displayed on the survey screen are pre-assigned evaluation values ​​for metric purposes. This makes it possible to clearly identify whether or not a visitor is a "HOT lead" by assigning a point evaluation value to them.

[0121] In this process, the evaluation score will be structured to adjust based on the impression of the exhibition booth, the deviation of the survey responses, and the response messages.

[0122] Here, the fourth data terminals 2-1 to 2-N, operated by the organizer, shall be equipped with an update function that updates the design standards, including the color tone, brightness, shape, size, and spatial representation of the exhibition booth, based on the impression of the exhibition booth.

[0123] Furthermore, the server device 1 includes a business negotiation guidance system 16-25 that analyzes the responses entered from the first data terminals 3-1 to 3-N in response to the questionnaire screen displayed by the questionnaire screen display unit 16-21, and guides the visitor and the exhibitor operating the third data terminal to a booth where they can begin business negotiations. Here, the booths are assumed to consist of real conference booths.

[0124] Figures 20 to 23 show examples of questionnaire screens displayed by the questionnaire screen display unit 16-21 shown in Figure 19.

[0125] In Figures 20 to 23, each questionnaire screen is set with directional headers H1 to H6 indicating the questionnaire scenario, and the number of inquiry items is limited to about 1 to 6, allowing visitors operating the first data terminals 3-1 to 3-N to answer immediately in an environment where their excitement is clearly felt upon arrival. Furthermore, the remarks field screen shown in Figure 23 is designed to allow for free and open comments, without setting text that would lead to business negotiations.

[0126] Here, by having visitors write messages (impressions (+ opinion, - opinion)), it becomes possible to create a summary that is effective during the subsequent LLM analysis. Furthermore, in the remarks column screen shown in Figure 23, after a visitor operating the first data terminal 3-1 to 3-N submits their response and presses the submit button H6-BT, it is automatically uploaded to a pre-configured questionnaire collection box (which can be specified by URL).

[0127] [Effects of the Fourth Embodiment] According to this embodiment, exhibitors can obtain appropriate questionnaire responses to gain feedback on new product development, changes in product design, and related product ideas and services, and can provide effective feedback to the exhibitors.

[0128] Since the content of the questionnaires is expected to differ from visitor to visitor, it is desirable to automatically generate a summary document tailored to the exhibition content using the AI ​​support unit 19 shown in Figure 2.

[0129] [Fifth Embodiment] In the above embodiment, we described a system in which the server device 1 maintains a one-to-one relationship with each visitor when the visitor administers an effective questionnaire to the exhibitor at an appropriate time, summarizes the response process, and notifies the first data terminals 3-1 to 3-N etc. operated by the visitor. However, in the case of multiple visitors, for example, a visitor and their supervisor may use multiple data terminals to visit the virtual exhibition and virtual showroom that they have booked on the same day. Furthermore, it is desirable to construct a system that is flexible enough to accommodate various configurations, such as each visitor visiting booths in any order they choose, or browsing the showroom and the exhibition.

[0130] Therefore, in an exhibition support system in which a server device 1 that provides a service of a virtual showroom built on the cloud via a predetermined communication medium can communicate with first data terminals 3-1 to 3-N operated by visitors to the virtual showroom, the server device 1 may be configured to include the following functional processing means.

[0131] Figure 24 is a block diagram showing the configuration of the exhibition support system according to this embodiment. Components identical to those in Figure 2 are denoted by the same reference numerals and their descriptions are omitted.

[0132] The server device 1 shown in Figure 24 includes a generation unit 16-1 that generates an attendant that can move within the virtual showroom, and a narration control unit 16-31 that controls the movement state of the attendant and the audio content that the attendant should explain to the user based on operation instructions from the first data terminals 3-1 to 3-N.

[0133] Here, the narration control unit 16-31 is configured to comprehensively control the difficulty level of the explanation, the speed of the explanation, and the language used for the explanation, based on the registration information of the visitors, for the audio content that the attendant should explain to the visitors.

[0134] Furthermore, the narration control unit 16-31 is configured to comprehensively control the attendant's actions, including facial expressions, appearance, and hand gestures, based on responses from the first data terminals 3-1 to 3-N.

[0135] Furthermore, the narration control unit 16-31 is configured to identify and automatically respond to the responses of multiple users.

[0136] Furthermore, the narration control unit 16-31 is configured to determine the level of coordination among multiple users who are present at the same time and to adjust the content of their responses accordingly.

[0137] Furthermore, the narration control unit 16-31 is configured to issue instructions to multiple first data terminals 3-1 to 3-N, operated by multiple visitors who are simultaneously visiting the exhibition, to gather at a desired location within the exhibition booth.

[0138] Furthermore, the narration control unit 16-31 is configured to control the screen display so as to mark the current location of multiple first data terminals 3-1 to 3-N operated by multiple visitors (visitors with a high degree of relationship, such as a boss and a subordinate) who are present at the same time.

[0139] Furthermore, the narration control unit 16-31 is configured to, upon receiving notification that the attendant has started moving from a predetermined explanation start position and moved to a predetermined waiting position, to have the attendant provide instructions to the visitor operating the first data terminals 3-1 to 3-N, guiding them to move to an exhibition booth independent of the currently displayed exhibition booth (for example, an exhibition booth reserved for business negotiations).

[0140] Furthermore, the narration control unit 16-31 controls the screen display to mark the current location of multiple first data terminals 3-1 to 3-N operated by multiple visitors who are visiting simultaneously. The narration control unit 16-31 is configured to control the screen display to swap or display two screens side-by-side the exhibition booths that each user is viewing, based on the marked exhibition booths being viewed. It is also possible to configure the narration control unit 16-31's functional processing as a method.

[0141] [Effects of the Fifth Embodiment] According to this embodiment, when there are multiple visitors, for example, a visitor and their supervisor may use multiple data terminals to visit the virtual exhibition and virtual showroom that they have booked on the same day. Furthermore, it is possible to construct a flexible system that allows each visitor to visit the booths in any order they choose, or to browse the showroom and the exhibition.

[0142] [Sixth Embodiment] The second data processing in the server device 1 in the second embodiment (movement display control between virtual space and real space) will be described in detail below.

[0143] Figures 25 and 26 are flowcharts showing the second data processing procedure in the server device 1 shown in this embodiment. (31) to (40) indicate the respective steps, and each step is realized by the CPU 13 loading the control program stored in the external memory 18 into the RAM 16 and executing it.

[0144] First, the CPU 13 determines whether the space where the attendant is staying is a virtual space based on the screen ID (ID = 0, 1) (31). If the CPU 13 determines that it is a virtual space, it then determines whether the transport space instructed by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is a real space (32). If the CPU 13 determines that the transport space is a real space (YES), it controls the switching to a display that transports the visitor from the virtual screen to the real space (33).

[0145] On the other hand, in step (31), if the CPU 13 determines that the transport space is not a virtual space (NO), it switches the display to indicate transport from real space to virtual space (34) and proceeds to step (38).

[0146] Next, when the CPU 13 moves to the real space, it displays a screen for selecting a business negotiation booth (not shown) and determines whether the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has given an instruction to select one of the business negotiation booths (35). If it determines that the visitor has not selected a business negotiation booth, it proceeds to step (40).

[0147] On the other hand, in step (35), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N has given an instruction to select one of the negotiation booths (negotiation rooms), it performs screen control to guide the visitor to the corresponding negotiation room based on the selected negotiation booth number (36).

[0148] Then, once the CPU 13 confirms that a business negotiation has ended in any of the negotiation booths (37), the CPU 13 further determines whether the visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N has requested a transfer space switch by operating the destination selection button on the panel display screen (not shown) (40). If the CPU 13 determines that the visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N has not requested a transfer space switch, the CPU 13 terminates this process.

[0149] On the other hand, in step (40), if the CPU 13 determines that there is a request to switch transport spaces from a visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N, it returns to step (31) and starts the process of viewing the attendant's explanation in the virtual-real space as a visitor.

[0150] Meanwhile, in step (34), the CPU 13 controls the display to switch from the real space to the virtual space, then restarts the attendant's narration (38). After that, the CPU 13 determines whether the visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N have issued a booth switching instruction (39). If the CPU 13 determines that the visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N have not issued a booth switching instruction, it returns to step (38).

[0151] On the other hand, in step (39), if the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N has issued a booth switching instruction, the system returns to step (32).

[0152] [Effects of the Sixth Embodiment] According to this embodiment, when a showroom and exhibition booths are made public on platform 1A, it is possible to switch between mutual public access and separate public access between a virtual mode exhibition using a virtual space and a real mode exhibition using a physical space, on a single system, according to the needs of visitors and exhibitors.

[0153] [Seventh Embodiment] The third data processing in the server device 1 of the third embodiment (reservation processing in virtual space and real space) will be described in detail below.

[0154] Figures 27 and 28 are flowcharts showing the third data processing procedure in the server device 1 shown in this embodiment. (41) to (57) indicate the respective steps, and each step is realized by the CPU 13 loading the control program stored in the external memory 18 into the RAM 16 and executing it.

[0155] First, the CPU 13 determines whether the reservation destination requested by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is a virtual-real space (41). If the CPU 13 determines that the reservation destination requested by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is a virtual-real space, the CPU proceeds to step (50).

[0156] On the other hand, in step (41), if the CPU 13 determines that the reservation destination requested by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N does not require a virtual-real space, the CPU 13 further determines whether the reservation destination requested by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N requires a virtual space (42). If the CPU 13 determines that the reservation destination requires a virtual space, the CPU 13 displays the first reservation screen on the displays 311 of the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (43).

[0157] Next, after the CPU 13 confirms that virtual reservation information has been entered by a visitor operating the first reservation screen via the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (45), the CPU 13 registers the virtual reservation information entered by the visitor operating the first reservation screen via the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N in the database 14 (46).

[0158] On the other hand, in step (42), if the CPU 13 determines that the reservation destination requested by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N does not require a virtual space, the CPU 13 presents the second reservation screen to the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (44). After confirming that real-world reservation information has been entered by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N via the second reservation screen (47), the CPU 13 registers the real-world reservation information entered by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N via the first reservation screen in the database 14 (48).

[0159] Next, the CPU 13 determines whether the reservation process from visitors operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has been completed (49). If the CPU 13 determines that the process has been completed, it terminates this process.

[0160] On the other hand, if the CPU 13 determines in step (49) that the process has not terminated, it returns to step (41).

[0161] On the other hand, if in step (41) the CPU 13 determines that it is a reservation request between the virtual and real spaces, it proceeds to step (50).

[0162] Here, the CPU 13 determines whether a visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N is requesting a showroom reservation. If the CPU 13 determines that a visitor operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N is requesting a showroom reservation, the CPU 13 displays a third reservation screen on the display 311 operating the first data terminals 3-1 to 3-N or the second data terminals 4-1 to 4-N (51), and accepts the showroom reservation information (between a virtual showroom and a real showroom) entered by the visitor.

[0163] On the other hand, in step (50), if the CPU 13 determines that the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N has not requested a showroom reservation, the CPU 13 displays a fourth reservation screen on the display 311 operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (52), and accepts the reservation information for showrooms (between the virtual exhibition and the real exhibition) entered by the visitor.

[0164] Next, the CPU 13 determines whether or not it is necessary to link the third reservation screen and the fourth reservation screen (53). If the CPU 13 determines that it is necessary to link the third reservation screen and the fourth reservation screen, it registers the virtual-real exhibition reservation information in the database 14 (54).

[0165] On the other hand, in step (53), if the CPU 13 determines that it is not necessary to link the third reservation screen and the fourth reservation screen, it registers the virtual-real showroom reservation information in the database 14 (55).

[0166] Next, the CPU 13 determines whether it is necessary to link each of the reservation information registered in the database 14 (56). If the CPU 13 determines that it is necessary to link them, it adds a parameter indicating the linkage between the third visit reservation and the fourth visit reservation and registers it in the database 14 (57), then returns to step (42).

[0167] On the other hand, if the CPU 13 determines in step (56) that it is not necessary to coordinate, it proceeds to step (49).

[0168] [Effects of the Seventh Embodiment] According to this embodiment, regardless of whether the transport space instructed by the visitor operating the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N is between real spaces or between virtual spaces, the visitor can be guided to efficiently perform a series of reservation processes that link each space with simple operations.

[0169] [Eighth Embodiment] The fourth data processing (questionnaire processing) in the server device 1 in the fourth embodiment described above will be explained in detail below.

[0170] Figures 29 and 30 are flowcharts showing the fourth data processing procedure in the server device 1 shown in this embodiment. (61) to (72) indicate the respective steps, and each step is realized by the CPU 13 loading the control program stored in the external memory 18 into the RAM 16 and executing it.

[0171] First, the CPU 13 counts the amount of text narrated by the attendant (61). This is because the amount of text required for narration may differ depending on whether it is a standardized narration or if the narration is modified based on interaction with visitors.

[0172] Next, the CPU 13 determines, based on the attendant's movement in the virtual space, whether it is time to ask visitors to complete a questionnaire (for example, a timing determined by the distance the attendant has moved within the space and the amount of narrated text) (62).

[0173] If the CPU 13 determines that it is not time to ask for a survey, it returns to step (61).

[0174] On the other hand, in step (62), if the CPU 13 determines that it is time to request the questionnaire, the CPU 13 displays the questionnaire screen on the displays 311 of the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N operated by the visitor (63).

[0175] Next, the CPU 13 analyzes the text content entered on the questionnaire screen (64). In this embodiment, points are assigned to favorable and negative responses, and the system is configured to extract keywords, add points, and determine the evaluation value. Next, the CPU 13 performs a process to index (display as a percentage) the evaluation value (65).

[0176] Next, the CPU 13 determines whether the index exceeds a predetermined threshold based on the answers to several questionnaire sheets (66), and if it determines that it exceeds the predetermined threshold, it proceeds to step (69).

[0177] On the other hand, in step (66), if the CPU 13 determines that a predetermined threshold has not been exceeded, it reads information from the database 14 that indicates that a return visit is expected and generates a message (67). After creating the generated message in a format to be attached to the questionnaire report, it sends the questionnaire report to the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N (68), and then terminates the process.

[0178] On the other hand, if it is determined in step (66) that a predetermined threshold has been exceeded, the system performs a process to guide the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N to the negotiation screen (69). This makes it possible to guide users to individually prepared negotiation sites by operating the negotiation screens presented on the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N.

[0179] Next, the CPU 13 operates the negotiation screens displayed on the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N to determine whether a negotiation has been concluded (70). If it determines that a negotiation has been concluded, it awards points usable in this system or on external e-commerce sites to the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N operated by the visitor (71), and returns to step (67).

[0180] On the other hand, if in step (70) the CPU 13 determines that the deal was not concluded, the CPU 13 notifies the first data terminals 3-1 to 3-N and the second data terminals 4-1 to 4-N of the next exhibition (72), and returns to step (67).

[0181] [Effects of the Eighth Embodiment] According to this embodiment, exhibitors can obtain appropriate questionnaire responses to gain feedback on new product development, changes in product design, and related product ideas and services, and can provide effective feedback to the exhibitors.

[0182] [Ninth Embodiment] The fifth data processing (real exhibition booth generation and display processing) in the server device 1 of the fifth embodiment will be described in detail below.

[0183] The system shown in this embodiment is an example of an exhibition support system that enables communication between a server device 1 that provides a service of providing a virtual showroom built on the cloud via a predetermined communication medium, first data terminals 3-1 to 3-N and second data terminals 4-1 to 4-N operated by visitors to the virtual showroom, third data terminals 5-1 to 5-N operated by exhibitors participating in the virtual showroom, and fourth data terminals 2-1 to 2-N operated by the organizer presenting the virtual showroom.

[0184] Figures 31 and 32 are flowcharts showing the fifth data processing procedure in the server device 1 shown in this embodiment. (81) to (92) indicate the respective steps, and each step is realized by the CPU 13 loading the control program stored in the external memory 18 into the RAM 16 and executing it.

[0185] First, the CPU 13 determines whether the exhibit information to be displayed is text (81). If it determines that the exhibit information to be displayed is text, it extracts text information from the exhibit information to be displayed (82). Specifically, it extracts text information from the exhibit information to be displayed obtained from the second data terminals 4-1 to 4-N to create different guidance messages that the attendant should speak according to the age group of the visitors (83).

[0186] On the other hand, in step (81), if the CPU 13 determines that the exhibition information to be displayed is not text, it extracts video information from the exhibition information to be displayed obtained from the second data terminals 4-1 to 4-N (84) and creates screen information to be switched and displayed according to the attendant's gestures (85).

[0187] Next, the CPU 13 acquires 3D image information corresponding to the real exhibition booths captured by the exhibitors at the third data terminals 5-1 to 5-N (86), and the CPU 13 executes a process to generate a digital twin of each exhibition booth (87).

[0188] Next, the CPU 13 executes the process of displaying the digital twin generated in step (87) within the virtual exhibition booth (88).

[0189] Next, the CPU 13 determines whether the visitors operating the first data terminals 3-1 to 3-N at the real exhibition have been instructed to move their viewpoint (89). If the CPU 13 determines that they have not been instructed to move their viewpoint, it returns to step (86) and repeats the same process.

[0190] On the other hand, in step (89), if the CPU 13 determines that a movement of the viewpoint has been instructed, the CPU 13 determines whether the trajectory of the viewpoint has changed significantly at the real exhibition (90), and if the CPU 13 determines that it has detected a change in viewpoint that should be switched, it controls the switching of the layout of the screen information to be presented to the first data terminals 3-1 to 3-N (91).

[0191] On the other hand, if in step (90) the CPU 13 determines that it has not detected a change in viewpoint that would cause the screen to switch, it returns to step (86). As a result, the layout of the screens presented is switched in response to instructions given by visitors operating the first data terminals 3-1 to 3-N to the attendant, allowing visitors to view exhibits from their desired direction on the real exhibition site in a natural way, following their moving viewpoint.

[0192] Next, the CPU 13 determines whether the operation screen displayed on the display 311 of the second data terminal 4-1 to 4-N is requesting instructions to leave the exhibition (92). If the CPU 13 determines that there is a request to leave, it terminates this process.

[0193] On the other hand, if in step (92) it is determined that the operation screen displayed on the display 311 of the second data terminal 4-1 to 4-N does not indicate a request to exit the exhibition, the process returns to step (89) and the same process is repeated.

[0194] [Effects of the 9th Embodiment] According to this embodiment, visitors can perceive the situation of the real exhibition, including the structure, exhibits, and content explanations of the real exhibition, through a digital twin screen on the virtual exhibition. This makes it possible to freely construct a complex exhibition support system that transcends the boundary between real and virtual.
