1-2. Detail of Information Processing

The information processing device 20 executes a process for performing control to output a notification content to the moving-body-mounted output device 30 or the communication device 40 or not to output a notification content, based on the travel information 120, the passenger information 130 and the notification content list 140. Information processing according to the present embodiment includes characteristic processes as described below.

FIG. 2 is a block diagram showing an example of functions related to the information processing according to the present embodiment. The information processing device 20 is provided with an information input unit 300, an output control processing unit 310 and a processing result output unit 340 as functional blocks. These functional blocks are realized by the processor 100 executing the program for notification to moving body passengers.

The information input unit 300 performs a process for inputting the travel information 120, the passenger information 130 and the notification content list 140 recorded in the storage device 110. After that, the inputted travel information 120, passenger information 130 and notification content list 140 are outputted to the output control processing unit 310.

The output control processing unit 310 is further provided with a notification content determination processing unit 320 and an output destination device determination processing unit 330. The output control processing unit 310 makes a determination about a notification content that passengers are to be notified of, based on the inputted travel information 120, passenger information 130 and notification content list 140, and makes a determination about an output destination device to which the determined notification content is to be outputted. Details of each of the notification content determination processing unit 320 and the output destination device determination processing unit 330 will be described later.

The notification content determination processing unit 320 determines whether the inputted travel information 120 and passenger information 130 are included in the notification content list 140 or not. If it is determined that the inputted travel information 120 and passenger information 130 are included in the notification content list 140, a notification content to be targeted by output control (hereinafter referred to as “a control target content”) and the degree of importance thereof are identified. The identified control target content and degree of importance thereof are generated as information decided to be notified, which the output destination device is to be notified of Details of the process of the notification content determination processing unit 320 will be described later.

The output destination device determination processing unit 330 determines whether or not the degree of importance of the control target content included in the information decided to be notified, which has been generated by the notification content determination processing unit 320, is at or above a predetermined level, and, according to a result of the determination, determines the output destination device of the control target content. Details of the process of the output destination device determination processing unit 330 will be described later.

Based on a result of the determination about the output destination device of the control target content determined by the output control processing unit 310, the processing result output unit 340 makes a setting for outputting the control target content to the moving-body-mounted output device 30 or the communication device 40.

FIG. 3 is a flowchart showing an example of the process of the notification content determination processing unit 320.

At step S100, the notification content determination processing unit 320 determines whether or not the travel information 120, or the travel information 120 and the passenger information 130 are included in the notification content list 140.

If it is determined that the travel information 120, or the travel information 120 and the passenger information 130 are included in the notification content list 140 (step S100; Yes), the process proceeds to step S110. Otherwise (step S100; No), the process proceeds to step S120.

At step S110, the notification content determination processing unit 320 generates a control target content and the degree of importance thereof, as information decided to be notified.

At step S120, the notification content determination processing unit 320 generates information decided to be notified, which shows that there is neither a control target content nor the degree of importance thereof.

At step S130, the notification content determination processing unit 320 outputs the information decided to be notified, which has been generated.

FIG. 4 is a flowchart showing an example of the process of the output destination device determination processing unit 330.

At step S200, the output destination device determination processing unit 330 determines whether or not the degree of importance of the control target content included in the information decided to be notified, which has been generated by the notification content determination processing unit 320, is at or above the predetermined level.

If it is determined that the degree of importance of the control target content included in the information decided to be notified is at or above the predetermined level (step S200; Yes), the process proceeds to step S210. Otherwise (step S200; No), the process proceeds to step S220.

At step S210, the output destination device determination processing unit 330 sets the moving-body-mounted output device 30 as the output destination device that is to be notified of the control target content.

At step S220, the output destination device determination processing unit 330 determines whether or not there is such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state in the connection state information included in the passenger information 130.

If it is determined that there is such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state (step S220; Yes), the process proceeds to step S230. Otherwise (step S220; No), the process proceeds to step S240.

At step S230, the output destination device determination processing unit 330 sets the moving-body-mounted output device 30 as the output destination device that is to be notified of the control target content.

At step S240, the output destination device determination processing unit 330 determines whether or not the notification request information included in the passenger information 130 indicates an unwanted notification.

If it is determined that the unwanted notification is not set (step S240; No), the process proceeds to step S250. Otherwise (step S240; Yes), the process proceeds to step S260.

At step S250, the output destination device determination processing unit 330 sets the communication device 40 as the output destination device that is to be notified of the control target content.

At step S260, the output destination device determination processing unit 330 sets “none” for the output destination device that is to be notified of the control target content.

At step S270, the output destination device determination processing unit 330 outputs information about the set output destination device.

FIG. 5 is a diagram showing an example of a result of the output control processing unit 310. Specifically, when it is determined in the information processing device 20 that the degree of importance of a control target content is at or above the predetermined level, the moving-body-mounted output device 30 is set as the output destination device of the control target content, and the passengers are notified of the control target content via the moving-body-mounted output device 30.

FIG. 6 is a diagram showing examples of a result of the output control processing unit 310. Here, three examples of, when it is determined by the information processing device 20 that the degree of importance of a control target content is not at or above the predetermined level, notifying the control target content based on the passenger information 130 will be given. Specifically, a first example is a case where there is such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state in the connection state information included in the passenger information 130. In this case, the moving-body-mounted output device 30 is set as the output destination device of the control target content, and the passengers are notified of the control target content via the moving-body-mounted output device 30.

A second example is a case where there is no such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state, and there are devices for which a setting of being notified of control target contents is made in the notification request information in the passenger information 130. In this case, the communication device 40 is set as the output destination device of the control target content, and the devices for which the setting of being notified is made are notified of the control target content via the communication device 40. On the other hand, for devices for which the unwanted notification of control target contents is set in the notification request information in the passenger information 130, the control target content is not notified.

A third example is a case where, there is no such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state, and there is no device for which the setting of being notified of control target contents is made in the notification request information in the passenger information 130. In this case, a control target content is set for neither the moving-body-mounted output device 30 nor the communication device 40 as the output destination device, and the passengers are not notified of the control target content.

An example other than the result examples shown in FIG. 6 will be given. Specifically, it is a case where the degree of importance of the control target content of the first example is not at or above the predetermined level, and there is such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state. In this case, the output destination device of the control target content is the moving-body-mounted output device 30, but it is assumed that, among the passengers, a passenger who has set the unwanted notification is also included. Therefore, when a plurality of moving-body-mounted output devices 30, each of which can make a notification for a predetermined partial range, are installed to make a notification for a whole range, a setting of outputting control target contents may not be made for a moving-body-mounted output device 30 for a predetermined partial range where there are only passengers who have set the unwanted notification.

Furthermore, an example other than the result examples shown in FIG. 6 will be given. Specifically, the same as the second example, it is the case where, there is no such a device carried by a passenger that the state of connection with the communication device 40 is a cutoff state, and there are devices for which the setting of being notified of control target contents is made in the notification request information in the passenger information 130. In this case, it is assumed that control target contents that the devices are notified of differ according to the devices. Here, control target contents for each device is set in the communication device 40, and each corresponding device is notified of a set control target contents via the communication device 40. As a method for deciding a control target content for each device, the information about positions and postures of the passengers in the sensor-obtained information in the passenger information 130, and the like may be used.

1-3. Effects

It is possible to, if the degree of importance of a control target content showing notification content targeted by output control is at or above a predetermined level, notify passengers of the control target content via a moving-body-mounted output device irrespective of types of devices carried by the passengers. On the other hand, when the degree of importance of the control target content is not at or above the predetermined level, passengers who do not require notification are not notified of the control target content, and passengers who require notification are notified of the control target content, in an environment where there is no such a device carried by a passenger that the state of connection with a communication device is a cutoff state. Therefore, in this case, it is possible to notify only the passengers who requests notification, of the control target content. Thus, according to the present disclosure, it becomes possible to control output of a notification content to an output destination device according to the degree of importance of the notification content and information about the passengers.

In the second embodiment, attention will be paid to a scene of, in the case where degrees of importance of control target contents are not at or above the predetermined level, notifying, among control target contents that passengers who require notification of control target contents are to be notified of, only control target contents requested by the passengers based on the passenger information. It is though that, among the passengers who require notification, passengers who request only notification of necessary control target contents are included. Therefore, in the second embodiment, control target contents requested by passengers are notified based on the passenger information.

FIG. 7 is a block diagram showing details of the passenger information 130 stored in the storage device 110 in a configuration example of a device for notification to moving body passengers according to the second embodiment. The notification request information in the passenger information 130 further includes individual level information. The individual level information is information about individual levels set by the passengers in order to notify, among control target contents that the passengers are to be notified, only control target contents desired by the passenger. The individual levels are individually set for control target contents the degrees of importance of which are below the predetermined level. Setting of the individual levels is performed, for example, by presenting control target contents the degrees of importance of which are below the predetermined level to passengers planning to use a moving body in advance, and each of the passengers responding thereto.

FIG. 8 is a flowchart showing an example of a process of the output destination device determination processing unit 330 of the device for notification to moving body passengers according to the second embodiment.

At step S300, if the unwanted notification is not set, the process proceeds to step S310.

At step S310, the output destination device determination processing unit 330 determines whether or not the degree of importance of a control target content is at or above an individual level.

If it is determined that the degree of importance of the control target content is at or above the individual level (step S310; Yes), the process proceeds to step S320. Otherwise (step S310; No), the process proceeds to step S330.

At step S320, the output destination device determination processing unit 330 sets the communication device 40 as the output destination device that is to be notified of the control target content.

At step S330, the output destination device determination processing unit 330 sets “none” for the output destination device that is to be notified of the control target content.

At step S340, the output destination device determination processing unit 330 outputs information about the set output destination device.

The individual levels set by the passengers may be controlled according to hours. For example, in a scene of a night bus or the like, notification may not be performed in the night-time if, even though the degree of importance of a control target content is at or above an individual level, the degree of importance of the control target content is below the predetermined level.

As described above, according to the second embodiment, it is possible to notify, among control target contents that each passenger who requires notification of control target contents is to be notified of, a control target content the degree of importance of which is determined to be at or above an individual level set by the passenger, based on individual levels set by passengers. Therefore, in this case, it is possible to notify, among the control target contents that the passenger is to be notified of, only the control target content requested by the passenger. Thus, according to the present disclosure, it becomes possible to control output of notification contents to an output destination device according to degrees of importance of the notification contents and information about passengers.
