Specifically, the load calculation unit 27 calculates the rotational direction and rotational speed of the first rotating body 17a, the second rotating body 17b, and the third rotating body 17c in the load output unit 17 of the guiding device 10 as the load condition. Do.

  The arrival determination unit 29 determines whether or not the person to be guided (the guidance device 10) has arrived at the guidance location based on the current position of the guidance device 10 and the position of the guidance candidate location P (the guidance location).

Subsequently, guidance processing performed by the guidance system 1 according to the present embodiment will be described. First, the process performed by the guidance device 10 will be described. FIG. 4 is a flowchart showing the procedure of the process performed by the guiding device 10.
When the guidance processing by the guidance system 1 is started, in the guidance device 10, the position detection unit 11 detects the current position of the guidance device 10 (S101). Further, the posture detection unit 13 detects the posture of the guiding device 10 (S102).

Next, the communication unit 15 transmits information on the current position of the guiding device 10 detected in S101 and the attitude of the guiding device 10 detected in S102 to the information processing device 20 (S103).
Although details will be described later, in the information processing apparatus 20, based on the information transmitted in S103, the guidance place for guiding the guidance subject is determined, and the load for guiding the guidance subject to the guidance place is determined. The conditions are calculated. Then, the load condition is transmitted from the information processing device 20 to the guidance device 10.

  Subsequently, the communication unit 15 acquires a load condition from the information processing device 20 (S104). The conditions of the load include the rotational direction and rotational speed of each of the first rotor 17a, the second rotor 17b, and the third rotor 17c of the load output unit 17.

  Next, the load control unit 19 controls the load output unit 17 to output a load based on the condition of the load acquired in S104 (S105). Specifically, the load control unit 19 rotates the first rotating body 17a, the second rotating body 17b, and the third rotating body 17c of the load output unit 17 based on the load conditions acquired in S104. A load is output so as to move from the current position of the guidance device 10 to the guidance location.

Thereafter, the position detection unit 11 detects the current position of the guidance device 10 (S106), and the posture detection unit 13 detects the posture of the guidance device 10 (S107).
Then, the communication unit 15 transmits information on the current position of the guiding device 10 detected in S106 and the attitude of the guiding device 10 detected in S107 to the information processing device 20 (S108).
Although details will be described later, in the information processing apparatus 20, based on the information transmitted in S108, it is determined whether or not the guidance target person (guiding device 10) has arrived at the guidance location, and has arrived When it is determined, the notification of arrival is transmitted from the information processing device 20 to the guiding device 10.

Next, it is determined whether the communication unit 15 has acquired an arrival notification described later from the information processing apparatus 20 (S109), and when the arrival notification is acquired (YES in S109), the guiding device 10 performs a series of processes. Finish.
When the communication unit 15 does not acquire the arrival notification (NO in S109), the load condition is transmitted again from the information processing device 20 to the guidance device 10 as described later, and the guidance device 10 returns to S104. Continue processing.

  Subsequently, processing performed by the information processing device 20 will be described. FIG. 5 is a flowchart showing the procedure of processing performed by the information processing apparatus 20.

When the guidance process by the guidance system 1 is started, in the information processing apparatus 20, the communication unit 21 acquires the situation of each guidance candidate place P from the guidance candidate place P itself, a device that monitors the guidance candidate place P, etc. To do (S201). Further, the communication unit 21 acquires information on the current position of the guidance device 10 and the attitude of the guidance device 10 from the guidance device 10 (S202). In the present embodiment, the situation of the guidance candidate place P, the current position of the guidance device 10, and the posture of the guidance device 10 correspond to the information on the guidance acquired by the acquisition means.
Subsequently, the storage unit 23 updates the information to be stored based on the information acquired by the communication unit 21 in S201 and S202 (S203).

  Next, the place determination unit 25 determines a guide place for guiding the person to be guided out of the plurality of guide candidate places P (S204). Specifically, the position determination unit 25 determines the position of the guidance candidate place P stored in the storage unit 23, the state of each guidance candidate place P acquired in S201, and the current position of the guidance device 10 acquired in S202. The guidance location is determined from among the plurality of guidance candidate locations P based on the posture of the guidance device 10 and.

  Regarding the determination method of the guidance place by the place determination unit 25, for example, based on the current position of the guidance device 10 and the position of the guidance candidate place P, setting the guidance candidate place P near the current position of the guidance device 10 as the guidance place it can. Further, based on the posture of the guiding device 10 and the position of the guiding candidate place P, the position determining unit 25 takes the guiding candidate place P on the extension of the direction in which the person to be guided wearing the guiding device 10 faces. can do. Furthermore, based on the situation of each guidance candidate place P, the place determination unit 25 can set the guidance candidate place P having a situation suitable for guiding the person to be guided as the guidance place.

Furthermore, based on the information acquired in S201 and S202, the place determination unit 25 estimates the future situation after a predetermined time has passed from the present, and determines the guidance place based on the estimated future situation. You may For example, the place determination unit 25 estimates the situation of the future guidance candidate place P based on the situation of each guidance candidate place P, and determines the guidance place based on the estimated situation of the future guidance candidate place P It is also good. In addition, the place determination unit 25 calculates the current moving speed of the guiding device 10 based on the current position of the guiding device 10 and the posture of the guiding device 10, and the position of the future guiding device 10 or the like on the basis of the calculated moving speed. The posture of the guidance device 10 may be inferred and the guidance location may be determined based on this.
In addition, the determination method of the induction | guidance | derivation place by the place determination part 25 is not limited above. Moreover, the specific example of the determination method of the induction | guidance | derivation place by the place determination part 25 is demonstrated in detail by a latter part.

Subsequently, the load calculation unit 27 calculates the condition of the load necessary to guide the person to be guided to the guidance place determined in S204 (S205).
Specifically, based on the current position of the guidance device 10 acquired in S202 and the position of the guidance location stored in the storage unit 23, the load calculation unit 27 determines the direction in which the person to be guided should travel (advancing direction) Decide.

  Next, the load calculation unit 27 determines the directions of the rotation axes of the first rotating body 17a, the second rotating body 17b, and the third rotating body 17c in the guiding device 10 based on the posture of the guiding device 10 acquired in S202. Understand the relationship with the determined direction of travel.

Then, the load calculation unit 27 determines the first rotary body 17a and the second rotary body based on the relationship between the direction of the rotation axis of the first rotary body 17a, the second rotary body 17b and the third rotary body 17c, and the traveling direction. The rotational direction and rotational speed for rotating 17b and the third rotary body 17c are calculated.
More specifically, the load calculating unit 27 calculates the first rotating body 17a, the second rotating member 17a, and the second rotating unit based on the calculation formula previously created based on the empirical rule and stored in the storage unit 23, and the grasped traveling direction. The rotation direction and the rotation speed for rotating the rotating body 17 b and the third rotating body 17 c are calculated.
The load calculation unit 27 stores a control map used to determine the rotation direction and rotation speed for rotating the first rotating body 17a, the second rotating body 17b, and the third rotating body 17c in the storage unit 23. The rotation direction and the rotation speed may be determined based on the control map and the travel direction that has been grasped.

Next, the communication unit 21 transmits the condition of the load calculated in S205 to the guidance device 10 (S206). Specifically, the communication unit 21 transmits the rotational direction and rotational speed of each of the first rotating body 17a, the second rotating body 17b, and the third rotating body 17c as the load condition. In the present embodiment, the load condition corresponds to the information on the load transmitted by the transmission means or the information on the guidance location.
In the guiding device 10, after the load is output by the load output unit 17 based on the control of the load control unit 19 (S105), the current position of the guiding device 10 and the attitude of the guiding device 10 are detected again (S106, S107) , And transmitted to the information processing apparatus 20 (S108).

Subsequently, the communication unit 21 acquires information on the current position of the guidance device 10 and the attitude of the guidance device 10 from the guidance device 10 (S207).
Then, whether the person to be guided (guide device 10) has arrived at the guidance location based on the position of the guidance location stored in the storage unit 23, and the current position of the guidance device 10 acquired in S207. It is judged whether or not it is negative (S208).

If arrival determination unit 29 determines that the guidance subject has not arrived at the guidance location (NO in S208), the process returns to S205 and continues. In this case, the load calculation unit 27 performs processing using the information acquired in S207 instead of the information acquired in S202 in S205.
Thus, the calculation of the load condition by the load calculation unit 27 in the information processing device 20 and the output of the load by the load output unit 17 in the guidance device 10 are repeated until the guidance target person arrives at the guidance location. To be done.

  On the other hand, when arrival determination unit 29 determines that the guidance target person has arrived at the guidance location (YES in S208), communication unit 21 indicates that the guidance target person has arrived at the guidance location with respect to guidance device 10. A notification (arrival notification) is sent (S209), and the series of processing is ended.

  As described above, in the guidance system 1, in the information processing apparatus 20, the guidance position for guiding the guidance target person is selected from the plurality of guidance candidate locations P, the current position or posture of the guidance device 10, the guidance candidate location P The decision is made based on conditions such as Thereby, for example, the person to be guided can be guided to a suitable place as compared with the case where the guidance place is predetermined.

Further, in the guidance system 1, the guidance device 10 outputs a load to make the person to be guided feel, thereby transmitting the direction to be advanced to the person to be guided.
Here, in the case of guiding the guidance target person using only vision or hearing, it is difficult to intuitively recognize the direction and the guidance position where the guidance target person should go, and it may be erroneously recognized. In particular, in the present embodiment, since the guidance location is determined by the information processing apparatus 20, there are cases where the guidance target person does not know the appearance, features, names, etc. of the guidance location. In such a case, even when the direction to be guided and the position of the guidance location are transmitted using vision and hearing, there is a risk that the guidance target can not easily reach the guidance location.

  On the other hand, in the present embodiment, it is compared with the case where, for example, only the sense of sight or hearing is used to transmit the direction to be guided to the person to be guided by transmitting the direction in which the person to be guided feels the load. Thus, it is possible to intuitively recognize the direction in which the guidance target person should go. As a result, it is suppressed that a guidance subject progresses to a wrong place, and it becomes easy to guide a guidance subject to a guidance place.

Subsequently, a specific application example of the guidance system 1 of the present embodiment will be described. The application of the guidance system 1 is not limited to the following application example.
(Example 1: Application of workers at a factory)
The guidance system 1 according to the present embodiment, for example, in a factory using a large machine having a plurality of work places as the guidance candidate place P, makes a worker who works in each work place as a guidance target person a suitable work place. It can be used to guide.
In such a large machine, for example, when performing maintenance etc., it is necessary for the workers to carry out the work at each work place in a predetermined order. For example, the workers need to move sequentially to the first work place, the second work place, the third work place... And complete the work at each work place. The guidance system 1 determines the work place to be guided from among the plurality of guidance candidate places P (work places) according to the work conditions at each work place, the current position of the workers, etc., and uses the load to Induce.

Specifically, in the information processing apparatus 20 of the guidance system 1, the communication unit 21 communicates with, for example, a large machine having a plurality of work places, and the work situation in each work place as the situation of the guidance candidate place P. Is acquired (S201). As the work status of each work place, there may be mentioned, for example, whether or not work at each work place is completed, and whether work by a worker is necessary.
Further, the communication unit 21 acquires information on the current position of the guidance device 10 and the posture of the guidance device 10 from the guidance device 10 (S202), and the storage unit 23 updates the information to be stored (S203).

  Subsequently, the place determination unit 25 determines a work place to be a guidance place based on the work situation of each work place, the current position of the guidance device 10, and the like (S204). For example, the place determination unit 25 has already completed the work at the first and second work places among the plurality of work places, and it is necessary to subsequently perform the work at the third and fourth work places And, when the current position of the guiding device 10 is closer to the third work place than the fourth work place, the third work place can be determined as the guidance place.

Next, the load calculation unit 27 calculates the condition of the load necessary to guide the worker to the guidance place (third work place) determined in S204 (S205).
Then, the communication unit 21 transmits the condition of the load calculated in S205 to the guidance device 10 (S206).

Further, in the guidance device 10 of the guidance system 1, when the communication unit 15 acquires the condition of the load transmitted from the information processing device 20 (S104), the load output unit 17 determines the condition of the load acquired by the communication unit 15. The load to be guided to the induction place (third work place) is output (S105).
As a result, a worker equipped with the guidance device 10 can arrive at a work place suitable for maintenance of a large machine, without referring to, for example, a manual or the like indicating the work procedure.

(Application example 2: Guidance of evacuees at the time of disaster)
Further, the guidance system 1 according to the first embodiment, for example, guides an evacuee as a guidance target person from a plurality of evacuation sites as a guidance candidate site P at a time of disaster such as an earthquake or a tsunami. It can be used.
At the time of disaster, it is necessary to guide evacuees to evacuation sites quickly. However, the evacuation site suitable for evacuating the evacuees may differ depending on the status of acceptance of the evacuees at the evacuation site, the state of the route to the evacuee, the type of disaster, the current position of the evacuees, and the like. The guidance system 1 determines an evacuation site suitable for guiding the evacuee from among the plurality of guidance candidate places P (evacuation site), and guides the evacuee using the load.

Specifically, in the information processing apparatus 20 of the guidance system 1, the communication unit 21 communicates with, for example, a disaster prevention center or the like for grasping the situation of a disaster, etc. The status of the person's acceptance and the status of the route to the evacuation site are acquired (S201). Further, the communication unit 21 may acquire information such as the status of a disaster in addition to the status of the guidance candidate place P. As information on the status of a disaster, for example, information such as the seismic intensity of an earthquake, the number of aftershocks, and the arrival time of a tsunami can be mentioned.
Further, the communication unit 21 acquires information on the current position of the guidance device 10 and the posture of the guidance device 10 from the guidance device 10 (S202), and the storage unit 23 updates the information to be stored (S203).

  Subsequently, the place determination unit 25 determines the evacuation place to be the guidance place based on the acquired acceptance situation of the evacuees at the evacuation place, the situation of the route toward the evacuation place, the current position of the guidance device 10, etc. S204). For example, the place determination unit 25 may select an evacuation site where a route from the current position of the guidance device 10 to the evacuation site is passable and is close to the current position of the guidance device 10 from among the evacuation sites where the evacuees can receive. It can be determined as the induction place.

  In addition, the place determination unit 25 estimates the future evacuation place and disaster situation after a predetermined time has passed from the present based on the acquired information, and the guidance place and the estimated place based on the estimated future situation. You may decide the evacuation site where For example, the place determination unit 25 estimates the crowded situation of a future evacuation site from the present situation of acceptance of evacuees at the evacuation site, and based on this, decides the evacuated place which is estimated not to be crowded as a guiding place can do. In addition, the place determination unit 25 can infer the situation of the future disaster from the current situation of the disaster, and based on this, can determine the evacuation place presumed to be less damaged by the disaster as the guidance place.

Next, the load calculation unit 27 calculates the condition of the load necessary to guide the evacuees to the guidance place (evacuation place) determined in S204 (S205).
Then, the communication unit 21 transmits the condition of the load calculated in S205 to the guidance device 10 (S206).

Further, in the guidance device 10 of the guidance system 1, when the communication unit 15 acquires the condition of the load transmitted from the information processing device 20 (S104), the load output unit 17 determines the condition of the load acquired by the communication unit 15. And outputs the load to be guided to the guidance place (evacuation place) (S105).
In this way, it is possible to quickly guide evacuees to a suitable evacuation site at the time of a disaster.

  At the time of a disaster, it may be difficult to visually guide the evacuees using a map or the like because the situation around them changes with the map or the evacuees are confused by the disaster. On the other hand, in the present embodiment, it is possible to intuitively recognize the direction in which the refugee should go by making the refugee feel the load and transmitting the direction in which the refugee should go. This makes it easy to guide the evacuees to the evacuation site even during a disaster.

Second Embodiment
Subsequently, a second embodiment of the present invention will be described. The same reference numerals are used for the same components as those in the first embodiment, and the detailed description thereof is omitted here.
FIG. 6 is a diagram showing a schematic configuration of a guidance system 1 to which the second embodiment is applied. In the guidance system 1 of the second embodiment, a plurality of guidance devices 10 are connected to the information processing device 20 via the network 50.

Are different. In addition, the guidance system 1 of the second embodiment determines the guidance location based on the distribution of the current positions of the plurality of guidance devices 10.
Each guidance device 10 and information processing device 20 have the same functional configuration as the example shown in FIGS. 2 and 3.

In the information processing apparatus 20 according to the second embodiment, the communication unit 21 transmits and receives information to and from the plurality of guidance devices 10. Specifically, the communication unit 21 acquires information on the current position of each guidance device 10 from each guidance device 10.
In addition to the position information of the plurality of guidance candidate places P, the storage unit 23 stores information on the current positions of the plurality of guidance devices 10 acquired by the communication unit 21.

Then, the place determination unit 25 includes the information on the plurality of guidance candidate places P, the information on the current position of the guidance device 10, and the information on the attitude of the guidance device 10, and the other guidance devices 10 stored in the storage unit 23. A guidance location is determined from among the plurality of guidance candidate locations P based on the information on the location.
For example, the place determination unit 25 selects, from among the plurality of guidance candidate places P, among the guidance candidate places P close to the current position of the guidance device 10, the guidance candidate places where the number of other guidance devices 10 located around is large ( For example, instead of P1), a guidance candidate location P (for example, P2) with a small number of other guidance devices 10 located in the periphery can be determined as the guidance location.

  As described above, when the place determination unit 25 determines the guide place based on the information on the current position of the other guide device 10, the guide target person can be guided according to the distribution of the person. Thereby, for example, when a guidance candidate place P (for example, P2) having a small number of other guidance devices 10 located in the periphery is determined as the guidance place, a large number of guidance target persons concentrate on a specific guidance candidate place P Induction is suppressed.

The guidance system 1 of the second embodiment can be used, for example, in a theme park having a plurality of attractions as a guidance candidate place P, for guiding a customer who has visited the theme park as a guidance target person. That is, each customer who has visited the theme park wears the guidance device 10. Then, the information processing device 20 determines the guidance location (attraction) of each guidance device 10 based on the current position of the other guidance device 10. Moreover, in each guidance apparatus 10, guidance to the determined attraction is performed using a load.
As a result, it is possible to guide customers according to the crowded state of each attraction, and it is possible to suppress concentration of customers on a specific attraction or the creation of an attraction without a customer.

Third Embodiment
Subsequently, a third embodiment of the present invention will be described. The same reference numerals are used for the same components as those in the first embodiment, and the detailed description thereof is omitted here. FIG. 7 is a diagram showing a schematic configuration of a guidance system 1 to which the third embodiment is applied.
In the first embodiment and the second embodiment, the information processing device 20 determines a guidance location from among a plurality of predetermined guidance candidate locations P. On the other hand, Embodiment 3 differs from Embodiments 1 and 2 in that the guidance candidate place P is not determined, and the information processing apparatus 20 determines an arbitrary place as the guidance place. .

In the guidance system 1 of the third embodiment, a plurality of (two in this example) guidance devices 10 are connected to the information processing device 20 via the network 50. Each guidance device 10 and information processing device 20 have the same functional configuration as the example shown in FIGS. 2 and 3.
In the information processing apparatus 20 according to the third embodiment, the place determination unit 25 relates to information on the current position of the guidance device 10 and information on the attitude of the guidance device 10, and relates to the current position of the other guidance device 10 stored in the storage unit 23. Based on the information, determine the guidance location. In other words, in the information processing apparatus 20 of the third embodiment, the place determination unit 25 determines the guidance place based on the positional relationship with the other guidance apparatus 10.
For example, as shown in FIG. 7, the place determination unit 25 determines the midpoint C or the like of the positions of the plurality of guidance devices 10 as the guidance place based on the information on the current position of the other guidance device 10.

The guidance system 1 according to the third embodiment can be used, for example, to meet children who have been lost and their parents in a shopping center or the like. Specifically, when the child and the parent respectively wear the guiding device 10, the middle point C or the like of the guiding device 10 is set as the guiding place based on the positional information of the guiding device 10 So you can guide your child and parents to the same place. Also, the parent may be guided to the origin of the child by setting the current position of the guidance device 10 worn by the child as the guidance location.
Further, for example, when a plurality of people are waiting, the guidance system 1 of the third embodiment can be used to gather a plurality of people in one place. Specifically, when each person who is in the meeting wears the guidance device 10, based on the position information of the respective guidance device 10, the middle point C of the plurality of guidance devices 10, etc. Do. Thereby, a plurality of people can be guided to the same place.

In Embodiments 1 to 3, the load condition output by the load output unit 17 of the guidance device 10 is calculated by the load calculation unit 27 of the information processing device 20, but the load condition The calculation of may be performed by the guidance device 10.
In this case, the information processing device 20 transmits the guidance location determined by the location determination unit 25 to the guidance device 10, and the guidance device 10 receives the guidance location received from the information processing device 20 and the current position and guidance of the guidance device 10. Based on the attitude of the device 10, the load condition is calculated.
Alternatively, the information processing device 20 determines the traveling direction in which the person to be guided should advance based on the guidance location determined by the location determination unit 25, and transmits the determined guidance location to the guidance device 10. Then, the guiding device 10 calculates a load condition based on the traveling direction received from the information processing device 20, the current position of the guiding device 10, and the attitude of the guiding device 10.

  Further, in the guidance system 1 according to the first to third embodiments, the load output unit 17 of the guidance device 10 outputs the load based on the condition of the load calculated by the information processing device 20. In the guiding device 10, the load control unit 19 may change the size of the load output by the load output unit 17 according to the situation or the like.

For example, the guidance device 10 can further include a situation grasping means for grasping the situation in the traveling direction for guiding the person to be guided by the load. Then, in the guiding device 10, the load control unit 19 can change the size of the load output by the load output unit 17 according to the situation in the traveling direction grasped by the situation grasping means.
Specifically, the load control unit 19 outputs the guidance device 10 by the load output unit 17 when the guidance device 10 recognizes that there is a failure that hinders the movement of the guidance subject in the traveling direction. The magnitude of the load can be reduced. More specifically, the size of the load can be reduced, for example, when there is human waste in the traveling direction of the person to be guided, or when the road condition or the like is not suitable for movement due to a puddle or the like. As a result, it is possible to reduce the moving speed of the guidance subject moving toward the obstacle, and to guide the guidance subject more safely.

  Furthermore, in the guiding device 10, the load control unit 19 may change the size of the load output by the load output unit 17 according to the degree of urgency of the guidance and the like. When using the guidance system 1 for guidance of evacuation from disasters, such as a highly urgent tsunami, for example, it is possible to increase the size of the load as compared with using it for other guidance with less urgent degree. Thereby, when the urgency of guidance is high, the guidance subject can be quickly guided to the guidance location.

Further, in the guidance system 1 according to the first to third embodiments, the guidance device 10 that outputs a load to the guidance target person and the information processing device 20 that determines a guidance location and calculates a load condition are different devices. Although provided, they may be provided in the same device. In other words, the guidance device 10 that outputs the load to the guidance target person may have the function of the information processing device 20 that determines the guidance location and calculates the load condition. In this case, since the exchange of information between the guidance device 10 and the information processing device 20 via the network 50 is not necessary, the configuration of the guidance system 1 can be simplified.
Here, when the guidance system 1 has a plurality of guidance devices 10, one guidance device 10 among the plurality of guidance devices 10 has the function of the information processing device 20, and the guidance for the other guidance devices 10 is taken. Information processing may be performed together, or each guidance device 10 may have the function of the information processing device 20.

Further, the guidance device 10 may further include transmission means for transmitting information and the like regarding guidance to the guidance target person by a sense other than the tactile sense. As such a transmission means, for example, a display device for transmitting information by vision using a video, a speaker for transmitting information by hearing using a voice, or the like can be used. Further, examples of the information related to the guidance transmitted to the guidance target person include information related to the guidance location calculated by the information processing device 20, the state of the guidance candidate location P acquired by the information processing device 20, and the like. In addition, the guidance subject may be alerted by the transmission means when, for example, the guidance subject is traveling in the wrong direction or when there is an obstacle in the traveling direction.
Thus, by transmitting information to the guidance subject by senses other than tactile senses, it becomes easier to recognize the direction and guidance location where the guidance subject should travel, and it becomes easier to guide the guidance subject to the guidance location.

Furthermore, the guiding device 10 transmits, for example, a signal or the like to a surrounding when the detecting device detects an abnormality in the guiding subject, or when the detecting unit detects an abnormality in the guiding subject, for example. It may further have transmitting means.
For example, the detection means detects an abnormality in the guidance subject when the guidance subject is buried in soil and the like and can not move or falls due to a seizure or the like. The detection means detects an abnormality of the person to be guided when the current position of the guidance device 10 detected by the position detection unit 11 and the posture of the guidance device 10 detected by the posture detection unit 13 do not change for a certain period. May be

And a transmission means transmits the signal and information which notify abnormality of a guidance subject to circumference | surroundings, when abnormality of a guidance subject is detected by a detection means. Specifically, the transmitting means transmits an audio signal notifying the surrounding person of the abnormality of the person to be guided by a speaker or the like. In addition, the transmitting unit may transmit information notifying an abnormality of the guidance target person to the information processing apparatus 20 or the fire service via the communication unit 15.
Thereby, when abnormality arises in a guidance subject person who equipped the guidance device 10, a guidance subject person can be discovered at an early stage.
