Description

The present invention relates to a guidance system, a guidance method, and a guidance program.

From the perspective of preventing crowd accidents and ensuring social distancing in recent times, there has been a demand for appropriate guidance of pedestrian crowds. On the other hand, there is known technology for guiding people to evacuate in the event of a fire (see, for example, Patent Document 1).

JP 2016-035765 A

However, the technology in Patent Document 1 was specialized for evacuation guidance in the event of a fire, and was intended to allow evacuees to evacuate quickly, so it was not suitable for guiding pedestrians, and there was a demand for technology that could appropriately guide pedestrians.

The present invention has been made in consideration of the above, and aims to provide a guidance system, guidance method, and guidance program that are capable of appropriately guiding pedestrians.

In order to solve the above-mentioned problems and achieve the object, the guidance system described in claim 1 is a guidance system for guiding a pedestrian, comprising a light source and a display control means for controlling light from the light source to display walking guidance information for guiding the pedestrian on a floor surface along which the pedestrian is walking, the walking guidance information being information displayed in multiple pieces at predetermined intervals in the walking direction of the pedestrian, the display control means dynamically displaying the multiple pieces of walking guidance information along the flow of the walking direction of the pedestrian at a predetermined speed corresponding to the flow of the multiple pedestrians, and the display control means moves display positions of the multiple pieces of walking guidance information along the walking direction of the pedestrian at the same predetermined speed.

The guidance system described in claim 2 is the guidance system described in claim 1, in which the display control means displays, as the walking guidance information, information indicating no-entry positions that are set at a predetermined interval in the walking direction of the pedestrian.

The guide system according to a third aspect of the present invention is the guide system according to the first or second aspect, wherein the light source irradiates light onto the floor surface from above or to one side of the floor surface.

The guidance method according to claim 4 is a guidance method for guiding a pedestrian, comprising a display control step in which a display control means controls light from a light source to display walking guidance information for guiding the pedestrian's walking on a floor surface along which the pedestrian is walking, the walking guidance information being information displayed in plurality at predetermined intervals in the walking direction of the pedestrian, the display control step dynamically displaying the plurality of walking guidance information along the flow of the walking direction of the pedestrian at a predetermined speed corresponding to the flow of the plurality of pedestrians, and the display control step moves display positions of the plurality of walking guidance information along the walking direction of the pedestrian at the same predetermined speed.

The guidance program described in claim 5 is a guidance program for guiding a pedestrian, which causes a computer to function as a display control means for controlling light from a light source and displaying walking guidance information for guiding the pedestrian on a floor surface along which the pedestrian is walking, the walking guidance information being information displayed in multiple pieces at predetermined intervals in the walking direction of the pedestrian, the display control means dynamically displaying the multiple pieces of walking guidance information along the flow of the walking direction of the pedestrian at a predetermined speed corresponding to the flow of the multiple pedestrians, and the display control means moves the display positions of the multiple pieces of walking guidance information along the walking direction of the pedestrian at the same predetermined speed.

According to the guidance system of claim 1, the guidance method of claim 4 , and the guidance program of claim 5 , by controlling the light from the light source and displaying walking guidance information on the floor surface, it becomes possible to appropriately guide the walking of pedestrians, for example.
Furthermore, by dynamically displaying walking guidance information at a speed corresponding to the flow of pedestrians and along the flow of pedestrians' walking direction, it is possible to control the pedestrian flow so that each pedestrian moves while maintaining an appropriate distance from each other.

According to the guidance system described in claim 2, by displaying information indicating no-entry positions set at a predetermined interval in the walking direction of pedestrians as walking guidance information, it becomes possible, for example, for pedestrians to maintain a state of lining up at an appropriate interval. In addition, for example, since the walking guidance information is displayed at positions where pedestrians are prohibited from entering, light from the light source can be irradiated onto the floor surface while avoiding pedestrians, so it becomes possible to reliably display the walking guidance information on the floor surface.

According to the guidance system described in claim 3 , the light source irradiates light onto the floor surface from above or to the side of the floor surface, which makes it possible, for example, to prevent the light source from becoming an obstacle to walking and to prevent the light source from being stepped on and damaged by pedestrians.

The guidance system according to the present invention is a system for guiding pedestrians, and includes, for example, a light source and a display control means.

This guidance system can be applied to any space where a relatively large number of pedestrians are present, such as a simultaneous exit from a large facility such as a stadium or movie theater, or the corridors of a station or large office building during rush hour.

The following embodiment describes the application of the guidance system to a passageway in any facility.

[II] Specific Contents of the Embodiment Next, specific contents of the embodiment will be described.

(composition)
First, the configuration of the walking control system will be described. Fig. 1 is a block diagram showing the functional concept of the walking control system according to the present embodiment. Fig. 2 is a side view showing a passageway to which the walking control system is applied. Fig. 3 is a plan view showing a passageway to which the walking control system is applied.

As shown in FIG. 2, multiple projection devices 1 are installed, but for ease of explanation, only one projection device 1 is shown in FIG. 1 as a representative example. Also, for ease of explanation, in FIG. 2, the position where the walking guidance information 4 is displayed is shown with a diagonal line, and in FIG. 3, for ease of explanation, the walking guidance information 4 is shown as a rectangle.

The walking control system 100 in FIG. 1 is a guidance system, and includes, for example, a projection device 1 and a server device 2, and these devices are capable of communicating with each other.

(Configuration - Projection device)
The projection device 1 in Fig. 1 is a device for outputting light to display the walking guidance information 4 in Fig. 2 and Fig. 3, and is, for example, a projector that projects an image or a laser device that irradiates a laser. The projection device 1 is, for example, provided on a ceiling as shown in Fig. 2, and irradiates light onto the floor surface of the passage from above the floor surface. The installation position of the projection device 1 is not limited to the ceiling, and the projection device 1 may be provided on a wall or a pillar, for example, and configured to irradiate light onto the floor surface of the passage from the side of the floor surface.

The projection device 1 in FIG. 1 includes, for example, a communication unit 11, a light source unit 12 (light source), a recording unit 13, and a control unit 14.

(Configuration - Projection device - Each part)
The communication unit 11 is a communication means for communicating with an external device (e.g., the server device 2). The light source unit 12 is a light output means for outputting light, such as an LED light source or a laser light source. The recording unit 13 is a recording means for recording programs and various data for operating the projection device 1. The control unit 14 is a control means for controlling the projection device 1, and is configured using, for example, a CPU, a RAM, and an internal memory such as a ROM.

(Configuration - Server Device)
The server device 2 in FIG. 1 is a device that controls the projection device 1, and is, for example, a single computer or a so-called cloud computer configured by distributing a plurality of computers.

The server device 2 in FIG. 1 includes, for example, a communication unit 21, a recording unit 22, and a control unit 23.

(Configuration - Server device - Each part)
The communication unit 21 is a communication means for communicating with an external device (e.g., the projection device 1). The recording unit 22 is a recording means for recording programs and various data for operating the server device 2. The control unit 23 is a control means for controlling the server device 2, and is configured using, for example, a CPU, a RAM, and an internal memory such as a ROM. The control unit 23 conceptually includes, for example, a display control unit 231.

The display control unit 231 is a display control means that controls the light from the light source unit 12 of the projection device 1 to display walking guidance information 4 on the floor surface on which the pedestrian 3 is walking.

(Configuration - Server device - Walking guidance information)
4 is a diagram showing an example of walking guidance information displayed on a floor surface. The "walking guidance information" 4 is information for guiding the walking of the walker 3, and is a concept including, for example, information indicating no-entry positions (positions where the walker 3 is prohibited from entering) set at predetermined intervals (predetermined intervals, for example, 2 to 2.5 meters) in the walking direction of the walker 3 (the direction in which the walker 3 walks), and is, for example, a concept including an image containing an arbitrary pattern or an arbitrary notice.

The "walking guidance information" 4 is, for example, an image showing a location where pedestrians 3 are prohibited from entering (as an example, a location corresponding to a rectangular area), and is a concept that includes an image containing a tiger pattern, as in FIG. 4(a), or an image containing a warning such as "Please avoid walking in this zone," as in FIG. 4(b).

The "walking guidance information" 4 is a concept that includes, for example, still images and dynamically moving videos (i.e. animations), and in this embodiment, we will explain the case of dynamically moving videos.

(process)
Next, a description will be given of a walking guidance information display process executed by the walking control system 100 according to the present embodiment. The walking guidance information display process is a process for displaying the walking guidance information 4. The timing of starting this walking guidance information display process is arbitrary, and may be started at a predetermined time period of a day (e.g., rush hour, etc.), or may be started when the server device 2 receives a start command from the administrator.

In this process, first, the display control unit 231 of the server device 2 transmits a walking guidance information display start signal to each projection device 1. The "walking guidance information display start signal" is a signal for starting the display of walking guidance information 4, and is, for example, a signal including type information indicating the type of walking guidance information 4 to be displayed (for example, either the type in FIG. 4(a) or FIG. 4(b)), direction information indicating the moving direction, and speed information indicating the moving speed. Each of these pieces of information may be set in advance by the administrator.

Here, for example, as shown in Figure 3, the case will be explained where the lower half of the drawing represents the walking direction to the left in the passageway and the upper half of the drawing represents the walking direction to the right, and where the flow of pedestrians 3 is assumed to be at a speed of about 5 kilometers per hour, which corresponds to brisk walking.

In this case, the display control unit 231 of the server device 2 transmits to each projection device 1 a walking guidance information display start signal that includes, for example, type information indicating the walking guidance information 4 in FIG. 4(a), direction information indicating the walking direction in FIG. 3, and speed information indicating a speed of 5 kilometers per hour.

On the other hand, when the control unit 14 of the projection device 1 receives a walking guidance information display start signal from the server device 2, it irradiates the floor surface with light from the light source unit 12 to display walking guidance information 4 corresponding to the information contained in the signal. In detail, as shown in FIG. 3, the control unit 14 of the projection device 1 outputs light from the light source unit 12 so that multiple pieces of walking guidance information 4 are displayed on the floor surface. In particular, the control unit 14 of the projection device 1 dynamically displays the walking guidance information 4 by moving the walking guidance information 4 in a direction along each walking direction at a speed of 5 kilometers per hour, as shown by the dashed arrows.

Then, the timing for ending the display of this walking guidance information 4 can be arbitrary. For example, when the server device 2 receives a stop command from the administrator, the server device 2 may send a walking guidance information display stop signal to each projection device 1, and when the projection device 1 receives the signal, the display may end. Alternatively, the display may be configured to end automatically when a predetermined time (e.g., 1 to 2 hours) has elapsed since the start of display. This concludes the explanation of the walking guidance information display process.

(Effects of this embodiment)
According to this embodiment, by controlling the light from the light source unit 12 and displaying the walking guidance information 4 on the floor surface, it becomes possible to appropriately guide the walking of the walker 3, for example.

In addition, by displaying information indicating no-entry positions set at a predetermined interval in the walking direction of the pedestrian 3 as the walking guidance information 4, it becomes possible, for example, for the pedestrian 3 to maintain a state of lining up at an appropriate interval. In addition, for example, since the walking guidance information 4 is displayed at a position where the pedestrian 3 is prohibited from entering, the light from the light source unit 12 can be irradiated onto the floor surface while avoiding the pedestrian 3, so it becomes possible to reliably display the walking guidance information 4 on the floor surface.

In addition, by dynamically displaying walking guidance information 4 along the flow of pedestrians 3 in the walking direction at a speed corresponding to the flow of pedestrians 3, it is possible to control the pedestrian flow (flow of pedestrians 3) so that each pedestrian 3 moves while maintaining an appropriate distance from each other.

In addition, by irradiating light from above the floor surface with the light source unit 12, it is possible to prevent the light source unit 12 from becoming an obstacle to walking, and also to prevent the light source unit 12 from being stepped on and damaged by pedestrians 3, for example.

[III] Modifications to the embodiments The above describes the embodiments of the present invention. However, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of each invention described in the claims.

(About pedestrian guidance information)
The features of the walking guidance information 4 described in the above embodiment may be changed as desired. For example, the display control unit 231 of the server device 2 may be configured to adjust the interval between adjacent pieces of walking guidance information 4 or the moving speed of the pieces of walking guidance information 4 according to any element (for example, the time period during which the walking guidance information 4 is displayed or the number of pedestrians 3).

In addition, for example, the walking guidance information 4 may be configured to display information indicating entry permitted positions (positions where pedestrians are permitted to enter) rather than no-entry positions.
