<1. Embodiment of this technology>

(Example of using voice guide)
FIG. 1 shows an example of appreciation using an audio guide in a facility such as a museum.

By using audio guides at museums, tourist facilities, and other facilities, viewers can see the highlights of exhibits such as paintings and sculptures, as well as things they need to know for deeper viewing, historical backgrounds, and stories. You can take a closer look at the exhibits while listening to the audio.

In FIG. 1, the user is listening to the audio guide reproduced on the user terminal 10 by using earphones while watching the painting. In this audio guide, matters related to the painting that the user is watching, the background of the times, and the like are reproduced, so that the user can enjoy the experience of viewing the painting that is being watched at the same time.

The user terminal 10 is a device dedicated to the guide, or a device such as a smartphone or tablet terminal on which the application for the guide is installed, a glasses-type wearable device, or the like. The user terminal 10 may have a function of displaying a moving image, a still image, an animation, or the like on the screen in addition to the function of reproducing the voice guide.

By the way, in a facility such as an art museum where an unspecified number of people move, the flow of people may become uneven and the flow may be stagnant.

On the other hand, by interspersing all the exhibits without placing guides, people can be thinned out, or people can be detected using sensors to analyze and predict the flow of people, and signs and entrances on the movement line. There are ways to control movements by mouth. However, it takes time and effort to guide such a flow of people by relying on manpower and know-how.

In addition, if only information is provided, it will be left to the independence of each person, and there is a possibility that it cannot be guided appropriately. As a result, the congestion situation becomes uneven, and each person must voluntarily avoid the congestion, so that he / she may not be able to do what he / she wants and his / her satisfaction with the facility may decrease. be.

Therefore, in this technology, in a facility such as a museum, by presenting an appropriate guide to the user, it is possible to smooth out the congestion of the facility in a more natural way, and the user's satisfaction with the facility can be improved. Try to improve. Hereinafter, embodiments of the present technology will be described with reference to the drawings.

(System configuration)
FIG. 2 shows a configuration example of the presentation system 1 as an embodiment of an information processing system to which the present technology is applied.

The presentation system 1 is composed of user terminals 10-1 to 10-N (N is an integer of 1 or more) and a server 20. In the presentation system 1, the user terminals 10-1 to 10-N and the server 20 are connected to each other via the network 30.

The user terminal 10-1 is configured as, for example, a guide-dedicated device, a smartphone, a tablet terminal, a glasses-type wearable device, a PC (Personal Computer), or the like. When the user terminal 10-1 is configured as a device such as a smartphone, a guide application downloaded via the network 30 is installed.

The user terminal 10-1 has a sensor unit 101 and a presentation unit 102.

The sensor unit 101 senses spatial information, time information, and the like, and outputs sensor data obtained as a result of the sensing. At the user terminal 10-1, the sensor data output from the sensor unit 101 is transmitted to the server 20 via the network 30.

The sensor unit 101 includes sensors such as a BLE sensor and an infrared sensor, as well as a camera, a microphone, and the like.

The BLE sensor is a sensor that uses BLE (Bluetooth Low Energy), which is a short-range wireless communication technology. An infrared sensor is a sensor that receives infrared rays, converts them into electric signals, and extracts and uses necessary information.

The camera outputs image data obtained by performing signal processing by photoelectric conversion of light from a subject as sensor data. The microphone receives sound as vibration of air and outputs sound data as its electric signal as sensor data.

In addition to the above-mentioned sensors, the sensor unit 101 includes, for example, an acceleration sensor that measures acceleration in three directions of the XYZ axes, a gyro sensor that measures the angular velocity of the three axes of the XYZ axes, and the heart rate and body temperature of the organism. Alternatively, various sensors such as a biological sensor that measures information such as posture, a proximity sensor that measures a proximity object, and a magnetic sensor that measures the magnitude and direction of a magnetic field (magnetic field) can be included.

The presentation unit 102 presents information so as to be perceived by the user by at least one sensory function of the user's visual, auditory, and tactile sensations. The presentation unit 102 includes a speaker, a display, and the like.

The speaker outputs sound according to the sound data supplied to the speaker. The presentation unit 102 may output sound from earphones or headphones connected wirelessly or by wire. The display displays an image according to the image data supplied to the display.

User terminals 10-2 to 10-N are configured in the same manner as user terminals 10-1. For example, each user has a different user terminal 10. In the following description, when it is not necessary to distinguish between the user terminals 10-1 to 10-N, it is referred to as the user terminal 10.

The server 20 is composed of a dedicated server or the like. The server 20 has a control unit 200 including a user identification unit 201, a user detection unit 202, a state analysis unit 203, a content control unit 204, and a presentation control unit 205. Further, the server 20 has a database such as a user DB 211, a context DB 212, and a content DB 213.

The server 20 receives the sensor data transmitted from the user terminal 10 via the network 30 and supplies the sensor data to the user identification unit 201 and the user detection unit 202.

The user identification unit 201 executes the user identification process based on the sensor data, and records the identification result in the user DB 211. In this user identification process, the sensor data is analyzed to identify a user in the vicinity of the user terminal 10, and information about the user is registered for each user.

The user detection unit 202 executes the user detection process based on the sensor data, and supplies the detection result to the state analysis unit 203. In this user detection process, one or a plurality of users (viewers) in a space (each area, etc.) in a facility such as a museum are detected by analyzing the sensor data.

The state analysis unit 203 executes the state analysis process based on the detection result supplied from the user detection unit 202, and supplies the analysis result to the content control unit 204 or the presentation control unit 205. In addition, the state analysis unit 203 can refer to the information stored in each database as needed when executing the state analysis process.

In this state analysis process, the unsteady state and the like related to the phenomenon of the space of facilities such as museums are analyzed. The unsteady state represents a state until a phenomenon in the space becomes a stable state, such as a state in which a specific area in the space of a facility such as a museum is in a congested state.

For example, when the viewer density in a specific area is above a certain value, when the difference between the viewer density in the entire area and the viewer density in the specific area is above a certain value, the viewer density in the specific area for a specific period is used. When the difference from the current viewer density exceeds a certain value, it is presumed that the specific area is in a congested state, and the state becomes unsteady.

The content control unit 204 processes the content such as the guide recorded in the content DB 213 based on the analysis result supplied from the state analysis unit 203, and supplies the content to the presentation control unit 205.

The presentation control unit 205 controls the presentation of the presentation information according to the analysis result of the unsteady state by the state analysis unit 203. The presentation control unit 205 can refer to the information stored in each database as needed when performing the presentation control.

The presentation control unit 205 presents content such as a guide supplied from the content control unit 204 to the presentation unit 102 of the user terminal 10 via the network 30. Further, the presentation control unit 205 presents a guidance stimulus for inducing the user's behavior to the presentation unit 102 of the user terminal 10 via the network 30 based on the analysis result supplied from the state analysis unit 203.

The user DB 211 records information (preference information, history information, etc.) about each user for each user. The context DB 212 records information about the context (steady state determination conditions, etc.). The content DB 213 records content such as a guide.

The network 30 is configured to include a communication network such as the Internet, an intranet, or a mobile phone network, and enables interconnection between devices using a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol). ..

Note that FIG. 2 shows the minimum configuration of the user terminal 10 and the server 20, and other functions may be included.

For example, in the user terminal 10, an auxiliary storage device such as a semiconductor memory, a communication module corresponding to wireless communication or wired communication such as cellular communication (for example, 5G) or wireless LAN (Local Area Network), or a physical button. It may be configured to include an operation unit such as a touch panel or a touch panel.

Further, the server 20 may be composed of a plurality of servers, or may be provided by a separate server as a service for each function. The service for each function may be provided not only by the same business operator but also by a different business operator for each service.

The presentation system 1 is configured as described above. In the presentation system 1 configured as described above, the unsteady state (congestion state, etc.) related to the spatial phenomenon of facilities such as museums is detected, and the contents of the guide regarding each area and exhibits are changed, or the contents of the guide are changed. By presenting an inducing stimulus for inducing the behavior of the viewer, control is performed so as to bring the space of the facility closer to a steady state.

(Flow of guide presentation process)
Next, the flow of the guide presentation process executed by each device constituting the presentation system 1 will be described with reference to the flowchart of FIG.

In the explanation of FIG. 3, it is assumed that a large number of viewers are viewing exhibits such as paintings installed in each area in the museum. Further, among the viewers, the user to be processed is also referred to as a target user.

In step S11, the state analysis unit 203 analyzes the viewer density of the next area on the route of the exhibit in the museum based on the detection result of the user in the space (in the target area) by the user detection unit 202.

In step S12, the state analysis unit 203 determines the level of the viewer density in the next area based on the analysis result of the viewer density. The high or low viewer density is determined by a predetermined threshold value determination.

If it is determined in the determination process of step S12 that the viewer density of the next area on the route is low, the process proceeds to step S13.

In step S13, the content control unit 204 and the presentation control unit 205 execute the first guide presentation control process, and the presentation unit 102 of the user terminal 10 moves the viewer (target user) to the next area. Present a guide to. FIG. 4 shows the details of the first guide presentation control process.

In the first guide presentation control process, the presentation is controlled so as to reduce the explanation amount of the guide in the current area by temporarily reducing the explanation amount of the default automatic guide or by editing the content and changing the explanation. (S41). When reducing the amount of explanation of the guide, the minimum amount of explanation of the guide should be secured.

Further, in the first guide presentation control process, the guide to be displayed is omitted from the audio guide (S42), or the guide that can be explained in other areas is changed to be performed in an area with a low viewer density (S42). S43) to control the presentation so as to reduce the amount of explanation of the voice guide.

Further, in the first guide presentation control process, the presentation is controlled so as to shorten the explanation time of the guide by accelerating the explanation of the guide by controlling the speaking speed and the interval of the voice guide (S44). Furthermore, by detecting the moving speed of the viewer, the movement speed is above a certain level, and / or for the viewer located in a certain place, the explanation of the next exhibit in the area is given in advance, and a guide suitable for the viewer is provided. Is controlled so as to be presented (S45).

In this way, when the viewer density of the next area on the route is low, the guide presentation control is performed so as to encourage the viewers in the current area to move to the next area. The process of each step shown in FIG. 4 is an example, and it is not always necessary to execute all the processes, and at least one process may be executed. Further, the content of the guide is not limited to the guide for each area, and may be a guide near the works of individual exhibits.

Returning to FIG. 3, when it is determined in the determination process of step S12 that the viewer density of the next area on the route is high, the process proceeds to step S14.

In step S14, the content control unit 204 and the presentation control unit 205 execute the second guide presentation control process, and the presentation unit 102 of the user terminal 10 so as to keep the viewer (target user) in the current area. Present a guide. FIG. 5 shows the details of the second guide presentation control process.

In the second guide presentation control process, the presentation is controlled so as to increase the explanation amount of the guide in the current area by temporarily increasing the explanation amount of the default automatic guide or by editing the content and changing the explanation. (S71). For example, when increasing the amount of explanation of the guide, a supplementary explanation of the exhibit may be added.

Further, in the second guide presentation control process, the guide to be displayed may be explained in duplicate in the voice guide (S72), or the guide that can be explained in another area may be changed to be executed in the current area (S72). S73) to control the presentation so as to increase the amount of explanation of the voice guide.

Further, in the second guide presentation control process, the presentation is controlled so as to extend the explanation time of the guide by decelerating the explanation of the guide by controlling the speaking speed and the interval of the voice guide (S74). In the second guide presentation control process, a different route from the normal route may be presented.

In this way, when the viewer density of the next area on the route is high, the viewers in the current area are controlled to present the guide so as to stay in the current area. The process of each step shown in FIG. 5 is an example, and it is not always necessary to execute all the processes, and at least one process may be executed.

Returning to FIG. 3, when the process of step S13 or S14 is completed, the process proceeds to step S15.

In step S15, it is determined whether or not the viewer (target user) who was viewing the exhibit at the museum has finished viewing. If it is determined in the determination process of step S15 that the viewer has not finished viewing, the process returns to step S11, and the above-mentioned process is repeated.

If it is determined in the determination process of step S15 that the viewer has finished viewing, the process proceeds to step S16. In step S16, the presentation control unit 205 ends the guide presented to the presentation unit 102 of the user terminal 10. When the process of step S16 is completed, the guide presentation process is completed.

The flow of the guide presentation process has been described above. In this guide presentation process, the configuration of the guide and the speed of explanation by the voice of the guide are changed according to the unsteady state (congested state) of each area. Since it is possible to encourage movement to the area or to stay in the current area, it is possible to smooth out the congestion of facilities such as museums in a way that is not unnatural. As a result, user satisfaction with facilities such as museums can be improved.

(Flow of induction stimulus presentation processing)
Next, the flow of the guidance stimulus presentation process executed by each device constituting the presentation system 1 will be described with reference to the flowchart of FIG.

In step S111, the state analysis unit 203 refers to the context DB 212 and acquires a preset steady state determination condition. The steady state determination condition is set such that the steady state in each area of the museum is in a quiet state and the unsteady state is in a congested state.

In step S112, the state analysis unit 203 analyzes the viewer density in the target area based on the detection result of the user in the target area by the user detection unit 202.

In step S113, the state analysis unit 203 determines whether or not the viewer density is in the unsteady state by applying the steady state determination condition to the analysis result of the viewer density.

If the determination process in step S113 determines that the viewer density is not in a non-steady state, that is, in a steady state, the process proceeds to step S114.

In step S114, the user identification unit 201 registers the information regarding the stimulus effective for each user in the user DB 211 as history information. Here, for example, some types of stimuli can be first presented, and stimuli that are individually effective for each user can be included in the history information.

On the other hand, if the determination process in step S113 determines that the viewer density is unsteady, the process proceeds to step S115.

In step S115, the presentation control unit 205 refers to the user DB 211 and acquires historical information regarding the stimulus that is effective for the target user.

In step S116, the presentation control unit 205 presents the guidance stimulus to the presentation unit 102 of the user terminal 10 based on the acquired history information. For example, here, a guidance stimulus for guiding the target user from a crowded area to a quiet area is presented. As a result, the congestion of facilities such as museums can be effectively smoothed. If the stimulus that is effective for the target user is not registered, the stimulus set by default may be presented.

When the process of step S114 or S116 is completed, the process returns to step S111, and the above-described process is repeated.

The flow of the induced stimulus presentation process has been described above. In this inductive stimulus presentation process, an inductive stimulus for guiding from a congested area to a quiet area is presented according to the unsteady state (congested state) of each area, and the viewer is urged to move to the quiet area. Therefore, it is possible to smooth out the congestion of facilities such as museums in a way that is not unnatural. As a result, user satisfaction with facilities such as museums can be improved.

(Example of presentation method)
Next, an example of the presentation control method for the induced stimulus and the like will be described with reference to the following (a) to (f).

(A) Use of priming effect Presentation using the priming effect may be performed. Here, the priming effect means that the processing of the preceding stimulus promotes or suppresses the processing of the subsequent stimulus.

For example, when the museum is crowded, by presenting the user with images and sounds that give the user a "busy and busy" stimulus before the viewer enters, the user's walking speed is subsequently increased. effective. Specifically, it is sufficient to present an image of a person moving at a certain speed or higher, an image of an urban area or a highway, or give a quick explanation in advance. In addition, music that has a fast tempo when it is crowded and a slow tempo when it is quiet may be presented in advance.

In addition, when the following areas are mixed, the user is presented with an image or sound that gives a "relaxing or relaxing" stimulus in the area in front of the area, and then the walking speed of the user. Has the effect of slowing down. Specifically, it is sufficient to present an image of a person sitting and relaxing, an image of the suburbs and nature, and to give a preliminary explanation.

The stimulus for obtaining the priming effect is not limited to the simple stimulus described above, and a stimulus related to the exhibition object may be given. That is, by giving a stimulus to a specific object such as a landscape, an animal, or a person, it is possible to disperse the interest in the exhibit.

The image or sound for giving a stimulus may be presented to the presentation unit 102 of the user terminal 10, or may be presented using a display, a speaker, or the like installed in the museum.

(B) Presentation of behavior-guided stimulus For example, in the case of a static exhibition such as an exhibition in a museum, a relatively quiet sound or a sound that changes when approaching is presented to the target user U in the crowded area A11. As a result, it is possible to induce the movement from the congested area A11 to the off-season area A12 (FIG. 7).

As the relatively quiet sound, for example, a BGM sound that is relatively quieter than the sound (such as a rustling sound) generated in the congested area A11 can be presented. Here, the relatively quiet BGM sound includes music with a relatively low volume, music with a slow tempo, music with a weak rhythm, and the like.

As the sound that changes when approaching, for example, when the target user in the crowded area A11 moves and approaches the quiet area A12, the change in the sound being presented so that the buzzing sound is settled, or the sound being presented is small. Changes such as Even if the target user U moves to an area different from the off-season area A12 (a place to be kept away, etc.), the sound being presented does not change.

Further, as the behavior-inducing stimulus in the case of a static exhibition, in addition to the guidance by the auditory stimulus using the sound as described above, the guidance by the visual stimulus using light or an image may be performed. For example, by presenting a visual stimulus that changes drastically to the target user U in the congested area A11 using light, an image, or the like, the movement from the congested area A11 to the quiet area A12 is induced. Can be done.

As shown in FIG. 8, when the route is not decided and there are a plurality of off-peak areas 12-1 and 12-2 with respect to the congested area A11 where the target user U is located, the rules set in advance are followed. The target user may be guided to one of the quiet areas 12-1 and 12-2.

Further, when presenting music, the movement of the target user can be induced by matching the timing of the end of the song with the timing of movement between areas. Further, the so-called cocktail party effect may be used to induce the movement of the target user. The cocktail party effect is a selective listening of voice, and is a phenomenon in which the target user can naturally hear his / her name and interests even if the space is noisy.

On the other hand, in the case of a dynamic event such as an outdoor festival, for example, by presenting a relatively loud sound or a sound that changes when approaching to the target user U in the crowded area A13, the crowded area A13 is quiet. It can induce movement to area A14 (Fig. 9).

As the relatively loud sound, for example, a noise sound like a crowd or a sound effect like a presentation can be presented. More specifically, it is sufficient to present relatively loud music, fast tempo music, and strong rhythm music to the exhibition hall where quiet and relaxed BGM is applied.

As the sound that changes when approaching, for example, when the target user U in the crowded area A13 moves and approaches the quiet area A14, the sound being presented becomes louder, the change accelerates, or an unclear sound is produced. Changes that become clear are included. Even if the target user U moves to an area different from the off-season area A14 (a place to be kept away, etc.), the sound being presented does not change.

Further, as the behavior-inducing stimulus in the dynamic event, the guidance by the visual stimulus may be performed in addition to the guidance by the auditory stimulus using the above-mentioned sound. For example, it is possible to induce a movement from the crowded area A13 to the quiet area A14 by presenting a relatively drastic visual stimulus to the target user in the crowded area A13 using light, an image, or the like. can.

Examples of light presented in FIGS. 10A and 10B show an example of the presented light. By expressing the direction of the off-peak area A14 with the light indicated by the arrow in the figure, the target user in the congestion area A13 can see the off-peak area. It induces the movement to A14. Alternatively, an animation or the like showing a flow line to a quiet area A14, which is a place to be approached, may be presented to a target user in the crowded area A13.

In the above description, the behavioral guidance stimuli are the auditory stimulus and the visual stimulus, but other sensory functions such as the tactile stimulus using clothing or equipment worn by the target user may be used. No.

(C) Personalization When dynamically changing the guide presented to the target user, it is of course controlled to handle all the target users uniformly, and in addition to that, the history information recorded in the user DB 211 is used. For users who are more effective when dynamically changing guides, make dynamic changes more frequently, and for users who are less effective, make dynamic changes less or less frequently. Control may be performed.

As described above, since there are some users who are not easily affected by the guide presentation control, such users are excluded from the target of the guide presentation control, and the user does not have the user terminal 10 and does not carry the guide. It can be treated in the same way. As a result, it is possible to control the viewers who are easy to follow the guide's presentation control, so that the congestion of facilities such as museums can be effectively smoothed and the viewers can avoid excessive guidance. There are merits.

Further, the guide may be dynamically controlled for each user by using the user's preference information recorded in the user DB 211. That is, the dynamic change of the guide is controlled by the presence or absence of the information registered in advance.

For example, when the user's preference information is registered, a more detailed guide can be presented to the user in front of the congested area based on the registered preference information. Further, in a crowded area, based on the registered preference information, the contents of the next area can be advanced in advance in advance, and the movement to the next area can be promoted.

Alternatively, when presenting the guidance stimulus to the target user, the history information recorded in the user DB 211 is used, and the user who is not easily affected by the guidance stimulus is excluded from the target of the guidance stimulus presentation control, and the user terminal 10 is possessed. It can be treated like a person who does not carry a guide. As a result, it is possible to control the viewer who is easy to follow the presentation control of the guidance stimulus, so that the congestion of facilities such as museums can be effectively smoothed and the viewer can avoid excessive guidance. There is a merit.

Further, an index related to the effect of the induced stimulus for each user (an index of easiness of producing the effect, etc.) may be calculated, and the presentation control of the induced stimulus may be performed based on the index. For example, for a user who is likely to be greatly affected by the induced stimulus, the induced stimulus may be suppressed, while for a person who is less likely to be affected by the induced stimulus, the induced stimulus may be strengthened.

In addition, when there are a plurality of guide presentation control methods and guidance stimulus presentation control methods, a presentation control method that is likely to have an influence is selected from a plurality of types of presentation control methods for each user. do it. For example, for a user who is easily affected by the speaking speed, the speaking speed of the voice guide may be controlled, and for a user who is easily affected by music, presentation control regarding music may be performed.

(D) Support for multiple people In the space of facilities such as museums, there are not only viewers who act alone, but also viewers who come in groups and act together.

At this time, if all the users in the group have the user terminal 10, the same guide is provided to each user. That is, if the guides are individually presented to the users in the group, some users will be guided to different areas and the groups will be separated. Therefore, the same guide is provided so that such a situation does not occur. offer.

Even if a plurality of users who come together have their own user terminals 10, if they are taking different actions in the facility and the groups are already separated, the user is asked to do so. , You may present the guide individually.

In addition, when a plurality of people come to the venue and act together, when only some users in the group have the user terminal 10, the user terminal 10 is held in the place where the user who does not carry the guide is present. A guide can be presented so that the user can move. As a result, even if there are users who do not carry guides in the group, the users in the group can act together.

Here, when acting together as a group, it is assumed that one user takes the lead and another user follows. Therefore, by discriminating the leading user and performing behavior guidance for the leading user, and performing presentation control so as not to perform behavior guidance for other users, the users in the group. Can act together.

The flowchart of FIG. 11 shows the flow of the guidance stimulus presentation process when a plurality of people act.

In step S211th, the state analysis unit 203 analyzes the position and trajectory of the viewer for a certain period of time based on the detection result of the user in the target area by the user detection unit 202.

In step S212, the state analysis unit 203 determines whether or not the target user is moving with someone else based on the analysis result of the position and trajectory of the viewer in the target area.

If it is determined in the determination process of step S212 that the target user is not moving with someone else, that is, the target user is acting alone, the process returns to step S211 and the above-described process is repeated.

On the other hand, if it is determined in the determination process of step S212 that the target user is moving together with someone else, that is, they are acting together in a group, the process proceeds to step S213.

In step S213, the state analysis unit 203 is a user in the group who is acting together based on the analysis result of the position and trajectory of the viewer in the target area, and is the user who has started to move before the member. To judge.

Here, by determining the user who moved before the member in the group, for example, the user who moves first from the place after staying in the vicinity of the exhibit, or when moving by multiple people, the user goes ahead in the route. The user who becomes the leading user is determined.

If it is determined in the determination process of step S213 that the user has moved ahead of the members in the group, that is, the user is the leading user, the process proceeds to step S214.

In step S214, the presentation control unit 205 presents an inductive stimulus such as an auditory stimulus or a visual stimulus to the presentation unit of the user terminal 10 held by the user who has moved earlier.

Further, if it is determined in the determination process of step S213 that the user is not the user who moved earlier than the member in the group, that is, the user is not the leading user, the process of step S214 is skipped.

That is, in this case, the inducing stimulus is not presented to the user terminal 10 possessed by a member other than the leading user in the group acting together, but these members are the leading users regardless of the inducing stimulus. Only the leading user needs to be presented with the inducing stimulus to follow.

When the process of step S214 is completed or the determination process of step S213 determines "No", the induction stimulus presentation process is completed.

Depending on the situation in the space of the facility such as a museum, it may be difficult to identify the leading user. In such a case, individual presentation control may be performed for each user.

Further, it is assumed that the leading user changes in time series, and in such a case, for example, the following presentation control can be performed.

That is, when the frequency of change of the leading user is higher than a certain value, the frequency of presenting the guidance stimulus to all the users in the group is controlled, or the frequency of change of the leading user is high. When the frequency is lower than a certain value, it is possible to control the presentation of the guidance stimulus to the person who has become the leading user at a predetermined timing. For example, the user who has been leading the user within a certain period from the timing of presenting the inductive stimulus can be regarded as the leading user.

The flow of the induced stimulus presentation process when a plurality of people act together has been described above.

When predicting congestion in a facility such as a museum using the flow rate of people, it is a group in which a plurality of people act together, and even one of the users in the group has a user terminal 10. Occasionally, multiple people acting together can be used as a group for flow rate prediction.

(E) Guidance when there are multiple routes when the route is undecided At facilities such as museums, there are cases where the route for viewing exhibits is decided, and there are cases where the route is not decided, and when the route is not decided, It is also assumed that there are multiple routes that can be guided.

FIG. 12 shows an example of guidance when there are a plurality of routes when the routes are not determined in a facility such as an art museum. FIG. 12 shows a floor view of the museum.

As shown in FIG. 12, in the space of the facility, an area A21 in which the exhibits a-1 to a-3 are installed, an area A22 in which the exhibits b-1 to b-3 are installed, and an exhibit There is an area A23 in which c-1 to c-3 are installed and an area A24 in which exhibits d-1 to d-4 are installed.

At this time, the area A21 is a congested area, and the areas A22, A23, and A24 are quiet areas. Focusing on the congested area A21, there are three areas A22 to A24 as quiet areas for guiding the viewer.

In area A21, if attention is paid to three users U2-1 to U2-3 (users in the frame of the broken line in the figure) who are acting together in a group among a large number of viewers, user U2-1 Since the off-peak area closest to the group of U2-3 is the area A24, when the induction stimulus is presented to the group of users U2-1 to U2-3, the presentation is controlled so as to be guided to the area A24. (Arrow G11 in the figure).

In controlling the presentation of the induced stimulus here, for example, the induced stimulus can be presented only to the user U2-2 who leads the group of the users U2-1 to U2-3.

Further, in the area A21, if the user U1 is focused on among a large number of viewers, the user U1 is a user who has moved from the area A23 to the area A21 (arrow T11 in the figure). Here, when the induction stimulus is presented to the user U1, the quiet area closest to the user U1 is the area A23, but since the area A23 has already been viewed, it is not the closest area A23 but the next closest. The presentation is controlled so that the user is already guided to the area A22, which is a quiet area (arrow G12 in the figure).

In this way, in a facility such as a museum, when there are multiple routes when the route is not decided, in principle, the user in the congested area is guided in the direction of the nearest off-road area, but once entered. Avoid directing to the area. Further, for example, when there are many exhibits installed in the area and there is a possibility that all the exhibits may not be seen, the preference of the target user is adjusted based on the preference information of the user registered in the user DB 211. Exceptions may be made, such as giving priority to the direction of the off-peak area where the exhibits are installed.

(F) Others The guidance in the above description is not limited to the state at that time, and a prediction may be added. Further, when a plurality of users are interacting with each other, such as when a plurality of users are acting together, the presentation control of the guided stimulus may be performed by participating in the dialogue. Furthermore, when a virtual crowd can be presented to the user terminal 10 by sound or video using AR (Augmented Reality) technology or the like, the flow of people, noise, etc. are controlled to be virtually presented. You may also lead to a quiet area.
