That is, when the advertisement is on the left side, a leftward arrow is displayed on the display 36 so that the pedestrian can see the left side. Also, when the advertisement is in the right direction, a rightward arrow is displayed on the display 36 so that the pedestrian can see the right direction. The display 36 is a transparent display through which the actual scenery can be seen, and an arrow image is overlaid (superimposed) on the actual scenery.

In the present embodiment, notification sounds (sound effects) are output from the speakers 35a and 35b. You may make it output a sound.

Also, the visual guidance operation may be changed according to the change in the positional relationship between the pedestrian and the advertisement. For example, when the pedestrian is away from the advertisement, the vibrations of the vibrators 34a and 34b, the notification sounds of the speakers 35a and 35b, and the display image of the display 36 are reduced. enlarges the vibrations of the vibrators 34a and 34b, the notification sounds of the speakers 35a and 35b, and the display image of the display 36, and in particular, increases the vibrations of the vibrators 34a and 34b and the speakers 35a and 35b as the pedestrian approaches the advertisement. The notification sound of 35b and the display image of the display 36 may be controlled to gradually increase in size. In this case, the positional information of the pedestrian is accumulated as positional history information for a predetermined period, and the change in the positional relationship between the pedestrian and the advertisement may be determined based on the positional history information.

Next, processing performed by the advertisement object visual determination unit 64 and the distribution information acquisition unit 65 of the roadside unit 3 according to the first embodiment will be described. FIG. 8 is an explanatory diagram showing an advertisement database stored in the storage unit 53 of the roadside unit 3. As shown in FIG.

The advertisement visual judgment unit 64 of the roadside unit 3 determines, based on the pedestrian position information, the head orientation information, and the line-of-sight direction information received from the pedestrian terminal 1 and the advertisement database stored in the storage unit 53, To specify an advertisement viewed by a pedestrian by determining whether or not the pedestrian views the advertisement.

The example shown in FIG. 8 is for a roadside unit 3 installed near a store, and information on a plurality of advertisements (signboards, posters, banners, etc.) displayed at the store is registered in an advertisement database. there is Specifically, an advertisement ID, pedestrian position information (latitude and longitude), head orientation (head direction), and viewpoint coordinates (line-of-sight direction) are registered in an advertisement database. With this advertisement database, it is possible to identify the advertisement that the pedestrian sees from the pedestrian's position information, head direction, and viewpoint coordinates. It is determined that it is not visually observed.

In the advertisement database, pedestrian position information (latitude, longitude) is defined by the range of the area where the pedestrian is located, head direction (head orientation) is defined by the range of direction, and viewpoint coordinates (line-of-sight direction) is defined within the coordinate range of the XY rectangular coordinate system.

Further, the distribution information acquisition unit 65 of the roadside unit 3 acquires the advertisement related information corresponding to the advertisement viewed by the pedestrian based on the advertisement database. In the advertisement database, an address (URL) representing the storage location of the corresponding advertisement related information is registered for each advertisement. With this advertisement database, it is possible to acquire advertisement-related information corresponding to advertisements viewed by pedestrians from a management server (not shown) that manages advertisement-related information.

In this embodiment, it is determined whether or not the pedestrian is looking at the advertisement based on the advertisement database. Based on the position information of the advertisement stored in the storage unit 53, whether or not the pedestrian is looking at the advertisement may be determined based on whether the line of sight of the pedestrian intersects with the advertisement. good.

Moreover, even if the pedestrian's line of sight is directed in the direction in which the advertisement exists, the pedestrian may be looking at an object in front of the advertisement or an object beyond the advertisement. Therefore, a distance sensor is provided in the wearable terminal 2 to measure the distance (viewpoint distance) to the object that the pedestrian is looking at (visual object). If the distance substantially matches the distance, it may be determined that the pedestrian is looking at the advertisement.

In addition, the detection direction of the ranging sensor is adjustable, and based on the line-of-sight direction detected by the line-of-sight sensor, the detection direction of the ranging sensor is adjusted so as to match the line-of-sight direction of the pedestrian, By detecting the distance to the facing object with the range sensor, the viewpoint distance can be measured with high accuracy.

Next, an operation procedure of the pedestrian terminal 1 according to the first embodiment will be described. FIG. 9 is a flow diagram showing the operation procedure of the pedestrian terminal 1. As shown in FIG.

In the pedestrian terminal 1, first, as shown in FIG. 9A, the message control section 21 acquires position information (latitude and longitude) of the own device from the positioning section 11 (ST101). Head direction information measured by the head direction measurement unit 41 based on the detection result of the direction sensor 31 in the wearable terminal 2 is acquired from the wearable terminal 2 (ST102). Then, a normal message is transmitted from the ITS communication section 12 to the roadside device 3 (ST103). This normal message includes the terminal ID and position information of the device itself, and the head direction information.

Next, in the pedestrian terminal 1, as shown in FIG. 9(B), when the ITS communication unit 12 receives the visual guidance message from the roadside unit 3 (Yes in ST104), the visual guidance control unit 22 controls walking. The wearable terminal 2 is controlled to perform a visual guidance operation for the person (ST105). At this time, the visual guidance message includes the terminal ID of the pedestrian terminal 1 and guidance direction information, and based on the terminal ID of the pedestrian terminal 1, it is determined whether or not the notification is directed to the own device. , based on the guidance direction information, the wearable terminal 2 is caused to perform a visual guidance operation corresponding to the instructed guidance direction.

At this time, as a visual guidance operation, one of the left and right vibrators 34a and 34b of the wearable terminal 2 is operated, a notification sound (sound effect) is output from one of the left and right speakers 35a and 35b, and the display 36 Show an arrow pointing left or right.

Next, the message control unit 21 acquires the head direction information measured by the head direction measurement unit 41 from the wearable terminal 2 based on the detection result of the direction sensor 31 in the wearable terminal 2 (ST106). Also, the line-of-sight direction measured by the line-of-sight direction measurement unit 42 is obtained from the wearable terminal 2 based on the detection result of the line-of-sight sensor 32 (ST107). Then, a visual condition report message is transmitted from the ITS communication section 12 to the roadside device 3 (ST108). This viewing state report message includes the terminal ID and position information of the own device, and viewing state information (head direction information and line-of-sight direction information).

Note that the visual condition report message is sent periodically until a predetermined reporting time elapses after the visual guidance message is received from the roadside unit 3, and when the reporting time elapses, the sight line direction information is not included. Return to normal message.

Further, in the present embodiment, the head direction information is added to the normal message, but the line-of-sight direction information may be added to the normal message in addition to the head direction information. In this case, the normal message also serves as the visual condition report message.

Next, in the pedestrian terminal 1, as shown in FIG. 9C, when the ITS communication unit 12 receives the information delivery message from the roadside device 3 (Yes in ST109), the information presentation control unit 23 performs a predetermined (ST110). At this time, the information distribution message includes the terminal ID of the pedestrian terminal 1 and advertisement-related information, and based on the terminal ID of the pedestrian terminal 1, it is determined whether or not the notification is directed to the device itself. Then, as an information presentation operation, the advertisement-related information included in the message is presented to the pedestrian. Specifically, the sound of the advertisement-related information is output from the speakers 35 a and 35 b, and the screen of the advertisement-related information is displayed on the display 36 .

Note that, in the pedestrian terminal 1, a warning based on the collision determination is performed separately from this flow. That is, the roadside device 3 detects a vehicle by radar and transmits a message including the position information of the vehicle to the pedestrian terminal 1. When the pedestrian terminal 1 receives the message from the roadside device 3, Based on the included position information of the vehicle and the position information of the own device (pedestrian), collision determination is performed to determine whether the vehicle is likely to collide with the own pedestrian, and the vehicle collides with the own pedestrian. The wearable terminal 2 is caused to perform an alerting operation when there is a risk of

Next, operation procedures of the roadside unit 3 according to the first embodiment will be described. FIG. 10 is a flowchart showing the operation procedure of the roadside unit 3. As shown in FIG.

In the roadside device 3, first, as shown in FIG. 10A, when the ITS communication unit 51 receives a normal message from the pedestrian terminal 1 (ST201), the pedestrian approach detection unit 62 detects that the pedestrian It is determined whether or not the user has approached within a predetermined distance (for example, 10 m) from the advertisement (ST202). At this time, the normal message includes the terminal ID and position information of the pedestrian terminal 1 and the head direction information. Based on the obtained position information of the advertisement, it is determined whether or not the pedestrian has approached within a predetermined distance from the advertisement.

Here, if the pedestrian has not approached within the predetermined distance from the advertisement (No in ST202), the process ends.

On the other hand, when the pedestrian approaches within a predetermined distance from the advertisement (Yes in ST202), the guidance direction determination section 63 determines the location information and head direction information of the pedestrian included in the received message, and the storage section Based on the positional information of the advertisement stored in 53, the direction in which the advertisement exists as seen from the pedestrian (guide direction: right or left) is determined (ST203).

Next, in message control section 61, a visual guidance message is transmitted from ITS communication section 51 to pedestrian terminal 1 (ST204). This visual guidance message includes the terminal ID of the pedestrian terminal 1 to which the notification is made and the guidance direction information that is the determination result of the guidance direction determination section 63 .

Next, in the roadside device 3, as shown in FIG. 10(B), when the ITS communication unit 51 receives the visual condition report message from the pedestrian terminal 1 (ST205), the advertisement visual determination unit 64 determines whether the pedestrian is walking. It is determined whether or not the person is looking at the advertisement (ST206). At this time, the visual condition report message includes the terminal ID and position information of the pedestrian terminal 1, the head orientation information, and the line-of-sight direction information. Based on the head direction information, line-of-sight direction information, and position information of the advertisement stored in the storage unit 53, it is determined whether or not the pedestrian is looking at the advertisement.

Here, if the pedestrian is not looking at the advertisement (No in ST206), the process ends.

On the other hand, if the pedestrian is looking at the advertisement (Yes in ST206), the message control section 61 transmits an information distribution message from the ITS communication section 51 to the pedestrian terminal 1 (ST207). This information distribution message includes the terminal ID of the pedestrian terminal 1 to which the notification is sent, and the advertisement-related information regarding the advertisement viewed by the pedestrian. At this time, based on the advertisement database (see FIG. 8) stored in the storage unit 53, the distribution information acquisition unit 65 acquires the advertisement related information corresponding to the advertisement viewed by the pedestrian.

By the way, the advertisement-related information distributed to the pedestrian terminal 1 may be changed in accordance with a change in the positional relationship between the pedestrian and the advertisement. For example, when the pedestrian is away from the advertisement, simple advertisement-related information is delivered, and when the pedestrian is near the advertisement, detailed advertisement-related information is delivered. As the pedestrian approaches the advertisement, more and more detailed advertisement-related information may be distributed. In this case, the positional information of the pedestrian is accumulated as positional history information for a predetermined period, and the change in the positional relationship between the pedestrian and the advertisement may be determined based on the positional history information.

Further, the advertisement-related information distributed to the pedestrian terminal 1 may be changed according to the pedestrian's attributes (age, sex, etc.). In this case, a table in which advertisement-related information for each pedestrian attribute is set is stored in the storage unit 53, and based on the pedestrian attribute included in the message transmitted from the pedestrian terminal 1, the pedestrian terminal 1 The advertisement-related information to be distributed may be selected.

Also, the information distributed to the pedestrian terminal 1 may be changed according to the situation around the pedestrian. For example, during normal times, advertisement-related information related to advertisements seen by pedestrians is distributed, and when pedestrians are involved in disasters such as earthquakes, instead of advertisement-related information, evacuation routes (current location route to an evacuation center), etc. may be distributed.

Also, the information delivered to the pedestrian terminal 1 may be changed according to both the circumstances around the pedestrian and the attributes of the pedestrian (healthy person, dementia patient, elderly person, etc.). For example, evacuation information distributed when a pedestrian is involved in a disaster such as an earthquake may guide a different evacuation route for a healthy person, a dementia patient, or an elderly person. Specifically, in the case of patients with dementia and the elderly, guidance is provided on evacuation routes excluding roads that are difficult to walk (steep slopes, roads with steps, gravel roads, etc.). Also, dementia patients and elderly people may be guided to their homes, bus stops, hospitals, welfare facilities, and the like.

Also, the information delivered to the pedestrian terminal 1 may be changed according to weather conditions and the like. For example, during or immediately after rain, we provide evacuation route guidance that excludes places where puddles tend to form, and during or immediately after snow, we exclude places where snow is difficult to melt or places where it is easy to fall due to freezing. Provide evacuation routes.

In addition to distributing information to the pedestrian terminal 1 and presenting the information to pedestrians on the wearable terminal 2 and the pedestrian terminal 1, in cooperation with a system that controls digital signage installed on the road, pedestrians Information may be presented to pedestrians by digital signage in the surrounding area. In this case, the digital signage may be provided with a function of visible light communication, and the address of a site that provides detailed information on evacuation information and the like may be presented to pedestrians by visible light communication. This is especially useful for elderly people.

In addition, information distribution to the pedestrian terminal 1 can be used to prevent lost children and elderly people from wandering. That is, the roadside device 3 acquires the position information of the protected person from the pedestrian terminal 1 possessed by the protected person (child, elderly person, etc.), and transmits the position information of the protected person to the guardian (child By distributing the information to the pedestrian terminal 1 possessed by a person such as a family member of an elderly person, the guardian can check the current position and movement route of the protected person.

Specifically, first, when the pedestrian terminal 1 of the protected person approaches the roadside device 3, the pedestrian terminal 1 of the protected person transmits the protected person's information (user ID, position history information, etc.) to the roadside device. Send to 3. In addition to the user ID and position history information, orientation information of the protected person may also be transmitted to the roadside device 3 . Next, the user ID of the protected person to be searched is transmitted from the pedestrian terminal 1 of the guardian to the roadside device 3 . Next, in the roadside device 3, when the user ID of the protected person acquired from the pedestrian terminal 1 of the protected person matches the user ID of the protected person acquired from the pedestrian terminal 1 of the guardian, the roadside device 3 transmits the protected person's information (user ID, location history information, etc.) to the pedestrian terminal 1 of the guardian. The orientation information of the protected person may also be transmitted to the pedestrian terminal 1 of the guardian. This makes it easier for the guardian to grasp which direction the protected person has gone. This allows the guardian to check the current position and moving route of the protected person. In addition, the roadside device 3 transmits the guardian's information (positional information, etc.) to the pedestrian terminal 1 of the protected person. This allows the protected person to check the current location of the guardian.

(Second embodiment)

Therefore, in the present embodiment, as shown in FIG. 11, a management server 5 (analyzer) is provided for analyzing the behavior of pedestrians according to visual guidance, and pedestrians visually observe advertisements according to visual guidance. In such a case, the location information of pedestrians and the identification information of advertisements at that time are accumulated, and the frequency of sighting of each advertisement by pedestrians in response to visual guidance is aggregated to identify advertisements with high advertising effect. do.

Specifically, when the roadside unit 3 detects that a pedestrian has visually viewed an advertisement in response to visual guidance, the pedestrian's position information and advertisement identification information (advertisement ID) at that time are sent to the roadside unit 3. It transmits to the management server 5 via the machine 3 . Note that network communication may be used between the roadside device 3 and the management server 5 .

In the management server 5, the information acquired from the roadside unit 3, that is, the position information of the pedestrian who saw the advertisement in response to the visual guidance, is registered in the database and managed. Analytical processing (statistical processing) is performed on the data. In this analysis process, for example, the number of pedestrians who viewed the advertisement (the number of people who viewed the advertisement) in accordance with the visual guidance is counted for each advertisement during a predetermined counting period. Then, the number of people viewing the advertisement is compared with a predetermined threshold to evaluate the advertising effectiveness of the advertisement.

As a result, as shown in FIG. 12, it is possible to present the user with an analysis result representing the magnitude of the advertising effect for each advertisement. In the example shown in FIG. 12, the magnitude of the advertising effect is evaluated in three levels of large, medium, and small. The magnitude of the advertising effect for each is displayed in different colors.

In addition, if a pedestrian sees an advertisement in response to visual guidance, and then enters a store related to the advertisement and purchases a product at that store, the advertisement It is assumed that there was a large advertising effect (traffic effect, response effect), and based on this, the advertising effect of the advertisement can be evaluated.

Therefore, in the present embodiment, the frequency of pedestrian behavior (entering a store, purchasing a product) after a pedestrian looks at an advertisement according to visual guidance is counted to measure the advertising effectiveness of the advertisement.

In this case, if the management server 5 detects the entrance of the pedestrian looking at the advertisement according to the visual guidance based on the location information of the pedestrian acquired from the pedestrian terminal 1 and the location information of the store. good. Also, at the time of payment at the store, the customer ID of the customer who purchased the product is obtained from the customer's smartphone or IC card, and information that links the customer ID and the pedestrian's terminal ID (pedestrian ID) , the terminal ID of the pedestrian who purchased the product is acquired, and the purchase of the product by the pedestrian who viewed the advertisement according to the visual guidance is detected.

Note that the results of tallying the frequency with which pedestrians view advertisements can also be used for marketing in shopping malls and the like. For example, it is possible to increase the effect of attracting customers by arranging a store whose advertisements are frequently seen by pedestrians in a place where people frequently pass by, such as in a shopping mall.

(Third embodiment)
Next, a third embodiment will be described. It should be noted that points not particularly mentioned here are the same as those in the above-described embodiment. FIG. 13 is an overall configuration diagram of an information distribution system according to the third embodiment.

In the above-described embodiment, the advertisement-related information about the stationary advertisement is distributed from the roadside unit 3 installed near the advertisement to the pedestrian terminal 1 by inter-road communication. , advertising vehicle-related information about the advertising vehicle is distributed from the vehicle-mounted terminal 4 mounted on the advertising vehicle to the pedestrian terminal 1 by pedestrian-to-vehicle communication.

That is, when the advertising vehicle approaches the pedestrian, the pedestrian is guided to look in the direction of the advertising vehicle, and when the pedestrian sees the advertising vehicle in response to this guidance, the advertising vehicle-related information about the advertising vehicle is presented to the pedestrian. presented to the person.

Next, an overview of the operation procedure of the information distribution system according to the third embodiment will be described. FIG. 14 is a sequence diagram showing an overview of the operating procedure of the information delivery system.

The pedestrian terminal 1 first transmits a normal message to the in-vehicle terminal 4 through pedestrian-to-vehicle communication. This normal message includes the terminal ID and position information (latitude and longitude) of the own device, and the pedestrian's head direction information acquired from the wearable terminal 2 .

When the in-vehicle terminal 4 receives a normal message from the pedestrian terminal 1 through inter-pedestrian communication, the in-vehicle terminal 4 performs walking based on the position information of the pedestrian included in the message and the position information of the own vehicle measured by the own device. It is determined whether or not a person has approached within a predetermined distance (for example, 10 m) from the own vehicle (pedestrian approach detection). Then, when the pedestrian approaches within a predetermined distance from the own vehicle, based on the pedestrian's position information, the own vehicle's position information, and the pedestrian's head direction information included in the received message, The direction (guidance direction) in which the own vehicle exists when viewed from the direction is determined (guidance direction determination).

Next, the in-vehicle terminal 4 transmits a visual guidance message to the pedestrian terminal 1 by pedestrian-to-vehicle communication. This visual guidance message includes the terminal ID of the pedestrian terminal 1 to be notified and guidance direction information that is the result of the guidance direction determination.

When the pedestrian terminal 1 receives the visual guidance message from the vehicle-mounted terminal 4 via pedestrian-to-vehicle communication, the pedestrian terminal 1 visually guides the pedestrian to look in the direction of the vehicle based on the guidance direction information included in the message. The wearable terminal 2 is controlled to perform guidance operation. In this embodiment, a pedestrian is notified of the direction in which the vehicle is present by visual guidance operations such as voice output, vibration output, and image display.

Next, the pedestrian terminal 1 transmits a visual condition report message to the in-vehicle terminal 4 through pedestrian-to-vehicle communication. This visual condition report message includes the terminal ID and position information of the own device, and the pedestrian visual condition information (head direction information and line-of-sight direction information) acquired from the wearable terminal 2 .

When the in-vehicle terminal 4 receives the visual condition report message from the pedestrian terminal 1 through inter-pedestrian communication, the in-vehicle terminal 4 receives the position information of the pedestrian terminal 1, the pedestrian's head direction information, and the line-of-sight direction information included in the message, and the information of the direction of the line of sight of the pedestrian. It is determined whether or not the pedestrian is looking at the own vehicle (vehicle visual determination).

Next, when the pedestrian is looking at the own vehicle, the vehicle-mounted terminal 4 transmits a message for information distribution to the pedestrian terminal 1 through pedestrian-to-vehicle communication. This information distribution message includes the terminal ID of the pedestrian terminal 1 to be notified, and advertising vehicle-related information regarding the advertising vehicle that the pedestrian is looking at. On the other hand, when the pedestrian is not looking at the own vehicle, the information distribution message is not transmitted.

When the pedestrian terminal 1 receives the information distribution message from the vehicle-mounted terminal 4 via pedestrian-to-vehicle communication, the pedestrian terminal 1 controls the wearable terminal 2 to perform an information presentation operation of presenting the advertising vehicle-related information included in the message to the pedestrian. .

Here, the present embodiment is similarly applicable to taxis instead of advertising vehicles. In this case, the vehicle-mounted terminal 4 in the taxi transmits information indicating that the taxi is empty to the pedestrian terminal 1 . Moreover, the present embodiment can be similarly applied to buses. In this case, destination information of the bus, bus stop information, etc. are transmitted from the in-vehicle terminal 4 on the bus to the pedestrian terminal 1 . This embodiment is particularly effective when a plurality of buses with different destinations stop at a bus stop and it is difficult to know which bus one wants to board.

In the same manner as in the second embodiment, the pedestrian-to-vehicle communication system of the present embodiment is also provided with the management server 5 (analyzer) so as to analyze pedestrian behavior according to visual guidance. good too. In this case, the management server 5 may collect information from the in-vehicle terminal 4 on the pedestrian who viewed the advertisement according to the visual guidance. Also, transmission of information from the vehicle-mounted terminal 4 to the management server 5 may be performed via the roadside device 3 .
