DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. However, more detailed explanations than necessary, such as detailed explanations of already well-known matters and duplicate explanations of substantially the same configurations, may be omitted. Note that the following explanations and the drawings referred to are provided to enable those skilled in the art to understand the present disclosure, and are not intended to limit the scope of the claims of the present disclosure.

[0012] [composition] <Information Processing System 100> First, a configuration of an information processing system 100 according to an embodiment of the present disclosure will be described with reference to Fig. 1. As shown in Fig. 1, the information processing system 100 includes an information processing device 1 and a plurality of moving objects 2.

[0013] The information processing device 1 is a device that distributes content to multiple mobile objects 2. The information processing device 1 is, for example, a computer such as a PC (Personal Computer) or a workstation. In the example shown in FIG. 1, the information processing device 1 is communicatively connected to multiple mobile objects 2, each via a network NW. The network NW is a communication network such as the Internet or an intranet. Note that, in the example shown in FIG. 1, the information processing device 1 is communicatively connected to multiple mobile objects 2 via the network NW, but direct communication without via the network NW may also be possible.

[0014] The moving object 2 is a device that can play back various contents while moving. An example of such a moving object 2 is an electric wheelchair equipped with a content playback device. However, the moving object 2 is not limited to this, and may be various personal mobility or transportation means such as a mobile vehicle having a cabin. The movement of the moving object 2 is controlled by a control unit 26 that the moving object 2 is equipped with, which will be described later.

[0015] In this disclosure, a mobile object 2 that records the content described below may be referred to as a "recording mobile object," and a mobile object 2 that plays back the content may be referred to as a "playback mobile object."

[0016] When multiple moving bodies 2 travel in a platoon, when one of the multiple moving bodies 2 (hereinafter referred to as the leading moving body) moves, the other moving bodies move in order following the leading moving body. When traveling in a platoon, the movements of the other moving bodies are controlled by the control unit 26 in each moving body.

[0017] The leading moving body when platooning or the other moving bodies when not platooning performs automatic driving to move along a predetermined route according to the control of the control unit 26. Alternatively, the leading moving body when platooning or the other moving bodies when not platooning performs autonomous driving to calculate an optimal route to the acquired destination and travel autonomously based on information acquired by sensors. Alternatively, the leading moving body when platooning or the other moving bodies when not platooning is manually driven by a passenger or a remote operator.

[0018] The number of the multiple moving bodies 2 may be two, or may be three or more. When the number of moving bodies 2 is two, one corresponds to the above-mentioned leading moving body, and the other corresponds to the other moving bodies. When the number of moving bodies 2 is three or more, one corresponds to the leading moving body, and the remaining multiple moving bodies correspond to the other moving bodies.

[0019] <Information processing device 1> Next, the configuration of the information processing device 1 will be described with reference to Fig. 2. The information processing device 1 includes a communication unit 11, a control unit 12, and a storage unit 13.

[0020] The communication unit 11 is a communication device that communicates with multiple mobile objects 2. The communication unit 11 receives, for example, content recorded by any of the multiple mobile objects 2 and information such as the position of the mobile object 2. The communication unit 11 also distributes content to the mobile object 2, for example. In the following description, content recorded by the mobile object 2 may be referred to as "recorded content," and content distributed to the mobile object 2 may be referred to as "distributed content."

[0021] The control unit 12 is a processor including, for example, a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The control unit 12 reads out a program stored in the ROM, expands it in the RAM, and provides content to a plurality of moving objects 2 according to the expanded program. The RAM forms a work area for temporarily storing various programs executed by the CPU and data related to the programs. The ROM is composed of a non-volatile memory or the like, and stores various programs and data used during control.

[0022] The storage unit 13 is configured with a large-capacity recording medium such as a hard disk drive (HDD) or a solid state drive (SSD), and stores various information used for control of the control unit 12. Details of the various information stored in the storage unit 13 will be described later.

[0023] <Mobile unit 2> Next, the configuration of the moving object 2 will be described with reference to Fig. 3. The moving object 2 includes at least a communication unit 21, a recording device 23, a playback device 24, and a control unit 26. The moving object 2 further includes a driving device 22, a position information acquisition unit 25, a storage unit 27, a speed information acquisition unit 28, and a direction information acquisition unit 29.

[0024] The communication unit 21 is a communication device that communicates with the information processing device 1. The communication unit 21 may be capable of communicating with other mobile objects 2 via or without a network NW. The communication unit 21 communicates with the information processing device 1 or other mobile objects 2 in a wired or wireless manner.

[0025] The driving device 22 is a device that moves the moving body 2. The driving device 22 moves the moving body 2 by driving, for example, wheels or caterpillars with the power of a motor or an engine. The operation of the driving device 22 is controlled by a control unit 26.

[0026] The recording device 23 is a device that records content such as images, audio, and comments. The recording device 23 is, for example, an input device such as a camera, a microphone, and a keyboard. When the recording device 23 records an image, the recorded image may be either a still image or a moving image. The operation of the recording device 23 is controlled by the control unit 26. The content data recorded by the recording device 23 may be stored in the memory unit 27. In the following description, the content data may be simply referred to as content. Note that the recording device 23 is not an essential component of the playback mobile body.

[0027] The playback device 24 is a device that plays back content. The playback device 24 can play back distributed content distributed from the information processing device 1. Recorded content recorded by another mobile object 2 is stored in the information processing device 1, and the distributed content is acquired from the information processing device 1 via the communication unit 21. The playback device 24 includes at least one of a display, a speaker, and an earphone, for example, and can play back at least one of an image and a sound. The operation of the playback device 24 is controlled by the control unit 26. Alternatively, the operation of the playback device 24 may be controlled by the control unit 12 of the information processing device 1. Note that the playback device 24 is not an essential component of the recording mobile object.

[0028] The position information acquisition unit 25 acquires, as position information, information indicating the position of the moving object 2. For example, when the moving object 2 performs automatic driving to move along a predetermined route, information indicating what kind of route the predetermined route is may be stored in the storage unit 27.

[0029] For example, the location information is information indicating which of specific points set in advance within a predetermined route the moving object 2 is located at. Also, when the moving object 2 is located between two different points, the location information is information indicating between which points the moving object 2 is located.

[0030] A known method may be adopted for the method of the location information acquisition unit 25 to acquire location information. For example, a first method is a method of installing multiple beacons at specific points and identifying the location based on radio waves obtained from the beacons. A second method is a method of identifying the location based on GPS signals received from GPS (Global Positioning System) satellites. A third method is a method of identifying the location of a moving object by storing the shapes and positions of objects stored in advance within a predetermined route, and comparing the surrounding environmental information recognized by a sensor such as a camera or LiDAR (Light Detection And Ranging) with the stored shapes and positions of the objects. A fourth method is a method of identifying the current location by calculating the moving distance and moving direction from a known point using odometry or the like.

[0031] The speed information acquisition unit 28 generates speed information related to the speed of the moving body 2. The speed information acquisition unit 28 generates the speed information of the moving body 2 based on, for example, the position of the moving body 2 acquired by the position information acquisition unit 25 and a change over time in the position of the moving body 2. Alternatively, the speed information acquisition unit 28 may generate the speed information of the moving body 2 by integrating the acceleration of the moving body 2 acquired using an accelerometer. Alternatively, the speed information acquisition unit 28 may generate the speed information of the moving body 2 based on the number of rotations of the wheels of the moving body 2. Furthermore, the speed information acquisition unit 28 may generate the speed information of the moving body 2 by using, for example, a laser Doppler speedometer.

[0032] The direction information acquisition unit 29 generates direction information related to the moving direction of the moving object 2. The direction information acquisition unit 29 generates the direction information of the moving object 2 based on, for example, the position of the moving object 2 acquired by the position information acquisition unit 25 and a change over time in the position of the moving object 2. Alternatively, the direction information acquisition unit 29 may generate the direction information of the moving object 2 based on a difference in the number of rotations of each wheel of the moving object 2.

[0033] The control unit 26 is a processor composed of, for example, a CPU, a ROM, and a RAM. The control unit 26 reads out a program stored in the ROM, loads it in the RAM, and controls the recording device 23 and the playback device 24 according to the loaded program. The RAM forms a work area for temporarily storing various programs executed by the CPU and data related to the programs. The ROM is composed of a non-volatile memory or the like, and stores various programs and data used during control.

[0034] The control unit 26 controls the driving device 22 to move the moving body 2. The movement of the moving body 2 by the control unit 26 may be either the above-mentioned platoon driving or autonomous driving. In addition, the moving body 2 may be moved either by automatic driving under the control of the control unit 26 or by manual driving by a passenger or a remote operator.

[0035] In the case of platooning, the moving body 2 recognizes the position of the moving body in front and moves along the travel path of the moving body in front while maintaining a certain distance from the moving body in front, and is controlled by the control unit 26. In addition, in the case of manual driving, the moving body 2 may be moved via the control unit 26 using an input device such as a joystick, a steering wheel, or a remote controller, or may be moved without the control unit 26, such as by being pushed by a caregiver.

[0036] The control unit 26 also controls the recording device 23 to record the content. The recording of the content is performed based on an instruction input by a passenger of the moving object 2, for example, via an input device. However, the present invention is not limited to this, and the recording of the content may be performed based on an instruction from the information processing device 1, for example.

[0037] Furthermore, the control unit 26 controls the playback device 24 to play back the distributed content distributed from the information processing device 1. The playback of the distributed content is automatically performed based on an instruction from the control unit 26 or the information processing device 1, for example, in accordance with the position information of the mobile object 2. However, this is not limited thereto, and the playback of the distributed content may be performed based on an instruction input by a passenger on the mobile object 2, for example.

[0038] The storage unit 27 is composed of a large-capacity recording medium such as an HDD or SSD. The storage unit 27 stores information about a predetermined route along which the moving object 2 moves, map information about the moving range of the moving object 2, data of the recorded content recorded by the recording device 23, and related data of the recorded content. The related data of the recorded content includes recording position information indicating the position at which the moving object 2 recorded, recording speed information indicating the moving speed of the moving object 2 when recording, recording direction information indicating the moving direction of the moving object 2 when recording, and time information, which will be described later. If the moving object 2 does not have the storage unit 27, the recorded content recorded by the recording device 23 may be directly transmitted to the information processing device 1.

[0039] Alternatively, the storage unit 27 may store data of distribution content and related data that has been recorded by another mobile object 2 and distributed via the information processing device 1. If the mobile object 2 does not have the storage unit 27, the distributed content may be streamed via the information processing device 1.

[0040] The data stored in the storage unit 27 differs depending on whether the moving object 2 is a recording moving object or a reproducing moving object as described above. The data stored in the storage unit 27 will be described in detail later.

[0041] 4A and 4B are schematic diagrams showing an example of the appearance of the moving body 2. FIG. 4A is a top view of the moving body 2, and FIG. 4B is a side view of the moving body 2. In the example shown in FIG. 4A and FIG. 4B, the moving body 2 is an electric wheelchair, and includes a seat 201, a display 202, and a speaker 203. This allows a passenger sitting in the seat 201 to see an image displayed on the display 202 and hear audio reproduced from the speaker 203.

[0042] In the example shown in FIG. 4A, the display 202 is configured to cover approximately half of the passenger's field of vision. This allows the passenger to simultaneously view the scenery through the display 202 and the image displayed on the display 202. The display 202 may be a transparent or semi-transparent transmissive display. In this case, the passenger can view the image displayed on the display 202 and the scenery through the display 202 superimposed on each other. When the display 202 is a transmissive display, the display 202 may cover almost the entire field of vision of the passenger, instead of approximately half of the field of vision. The display 202 may also display the surrounding scenery in real time captured by a camera installed in the moving body 2 and the distributed content that has been distributed superimposed on each other. In this case, the passenger can enjoy the distributed content while viewing, for example, the front in the direction of travel, and can obtain a content experience that is safe and highly immersive.

[0043] 4A and 4B, the moving body 2 includes a plurality of wheels 204. At least some of the wheels 204 are driven by the driving device 22 (see FIG. 3), thereby allowing the moving body 2 to move.

[0044] [Operation] The operation of the information processing system 100 will be described below with reference to Fig. 5 to Fig. 23. In the following, it is assumed that the traveling method of the moving bodies is that the leading moving body performs automatic driving to move along a predetermined route under the control of the control unit 26, and the other moving bodies located behind perform manual driving operated by the passengers so as to follow the leading moving body. As described above, the traveling method of the moving bodies includes autonomous driving in addition to platoon driving, but the operation of the information processing system 100 is common even in the case of autonomous driving.

[0045] In the following, among the multiple moving bodies 2 included in the information processing system 100, a recording moving body that records content will be referred to as a first moving body 2_1, which is a leading moving body, and a reproducing moving body that reproduces the recorded content recorded by the first moving body 2_1 will be referred to as a second moving body 2_2, which is another moving body. Note that the recording moving body is not limited to the leading moving body, and the reproducing moving body is not limited to the other moving bodies.

[0046] FIG. 5 is a diagram showing the relationship between the moving distance and time between the first moving body 2_1 and the second moving body 2_2, and FIG. 6 to FIG. 18 are schematic diagrams showing the positions of the first moving body 2_1 and the second moving body 2_2 on a predetermined time axis in FIG. 5. In the example shown in FIG. 5, it is assumed that the first moving body 2_1 and the second moving body 2_2 guide visitors along a pre-set route in an art museum or a museum. A route is set for the first moving body 2_1 to sequentially view four exhibits, exhibit 1 to exhibit 4. The route is an example of a predetermined route. On the route, suitable points for viewing each exhibit are set, and in the following description, the point for viewing exhibit 1 is described as the first point P1, the point for viewing exhibit 2 is described as the second point P2, the point for viewing exhibit 3 is described as the third point P3, and the point for viewing exhibit 4 is described as the fourth point P4. The vertical axis of FIG. 5 represents the traveled distance, and the horizontal axis represents the time.

[0047] In the example shown in Fig. 5, first, the first moving body 2_1 moves along a predetermined route, and the second moving body 2_2 moves along the same route as the first moving body 2_1, following the first moving body 2_1. Therefore, the first moving body 2_1 and the second moving body 2_2 move along the same route. In the example shown in Fig. 5, there is one second moving body 2_2 that reproduces the distribution content, but there may be multiple second moving bodies 2_2. Note that there is only one first moving body 2_1 that records the content in this example.

[0048] In an initial state, both the first moving body 2_1 and the second moving body 2_2 are located at a first point P1. FIG. 6 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 in the initial state. FIG. 6 shows examples of routes connecting exhibit 1 to exhibit 4, first point P1 to fourth point P4, and first point P1 to fourth point P4. In FIG. 6, the route connecting first point P1 to fourth point P4 is indicated by a dashed arrow. FIG. 6 shows a state in which both the first moving body 2_1 and the second moving body 2_2 are located at the first point P1.

[0049] For example, when the first moving body 2_1 is located at the first point P1, the first moving body 2_1 starts recording content based on an instruction from the passenger. The recorded content recorded by the first moving body 2_1 includes at least one of images and sounds such as the appearance of the exhibit 1 as seen from the first moving body 2_1 and comments from the person riding on the first moving body 2_1. The recording of content by the first moving body 2_1 continues after the first moving body 2_1 arrives at the fourth point P4 until the content recording at the fourth point P4 is completed, unless the passenger issues an instruction to stop the recording. In other words, the first moving body 2_1 continues recording content both while moving and while temporarily stopped.

[0050] In the example shown in Fig. 5, the first moving body 2_1 starts moving toward the second point P2 at time T1. Then, the second moving body 2_2 starts moving toward the second point P2 at time T2. Fig. 7 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T1 to time T2.

[0051] The first moving body 2_1 arrives at the second point P2 at time T3 and stops temporarily to allow passengers to view the exhibit 2. The second moving body 2_2 is in the middle of moving from the first point P1 to the second point P2 at time T3. Fig. 8 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T2 to time T3.

[0052] The first moving body 2_1 starts moving toward the third point P3 at time T4. The second moving body 2_2 is still moving from the first point P1 to the second point P2 at time T4. Fig. 9 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T3 to time T4.

[0053] The second moving body 2_2 arrives at the second point P2 at time T5 and stops temporarily to allow passengers to view the exhibit 2. The first moving body 2_1 is in the middle of moving from the second point P2 to the third point P3 at time T5. Fig. 10 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T4 to time T5.

[0054] The first moving body 2_1 arrives at the third point P3 at time T6 and stops temporarily to allow passengers to view the exhibit 3. The second moving body 2_2 also stops temporarily at the second point P2 at time T6. Fig. 11 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T5 to time T6.

[0055] The second moving body 2_2 starts moving toward the third point P3 at time T7. The first moving body 2_1 pauses at the third point P3 even at time T7. Fig. 12 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T6 to time T7.

[0056] The first moving body 2_1 starts moving toward the fourth point P4 at time T8. The second moving body 2_2 is in the middle of moving from the second point P2 to the third point P3 at time T8. Fig. 13 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T7 to time T8.

[0057] The first moving body 2_1 arrives at the fourth point P4 at time T9 and stops temporarily to allow passengers to view the exhibit 4. The second moving body 2_2 is still in the middle of moving from the second point P2 to the third point P3 at time T9. Fig. 14 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T8 to time T9.

[0058] The second moving body 2_2 arrives at the third point P3 at time T10 and stops temporarily to allow passengers to view the exhibit 3. The first moving body 2_1 also stops temporarily at the fourth point P4 at time T10. Fig. 15 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T9 to time T10.

[0059] The second moving body 2_2 starts moving toward the fourth point P4 at time T11. The first moving body 2_1 pauses at the fourth point P4 even at time T11. Fig. 16 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T10 to time T11.

[0060] The second moving body 2_2 starts moving toward the fourth point P4 at time T12. The first moving body 2_1 pauses at the fourth point P4 even at time T12. Fig. 17 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 from time T11 to time T12. Fig. 18 is a diagram illustrating the positions of the first moving body 2_1 and the second moving body 2_2 after time T12.

[0061] The first moving body 2_1 stops recording when it arrives at the fourth point P4 and completes recording of the content at the fourth point P4. While the first moving body 2_1 is moving along a predetermined route, the first moving body 2_1 may transmit the recorded content to the information processing device 1 at any time, or may transmit a certain amount of recorded content to the information processing device 1 collectively after recording of the content to a certain extent.

[0062] As described above, the first moving body 2_1 and the second moving body 2_2 move sequentially along a predetermined route with a time difference. It is preferable that the second moving body 2_2 moves following the trajectory of the first moving body 2_1, but the second moving body 2_2 does not have to follow exactly the same trajectory as the first moving body 2_1.

[0063] The second moving body 2_2 receives the recorded content recorded by the first moving body 2_1 as the distributed content from the information processing device 1. Then, the second moving body 2_2 plays the distributed content so that the current location of the second moving body 2_2 and the location where the first moving body 2_1 recorded are the same. As a specific example, the second moving body 2_2 receives the recorded content recorded at a point where the first moving body 2_1 can view an exhibit as the distributed content, and plays the distributed content when the second moving body 2_2 is located at the point where the exhibit can be viewed. More specifically, the second moving body 2_2 receives the recorded content that was started to be recorded when the first moving body 2_1 arrived at the point where the exhibit can be viewed as the distributed content, and starts playing the distributed content when the second moving body arrives at the point where the exhibit can be viewed.

[0064] The inclination of the line segment in FIG. 5 corresponds to the moving speed of each moving body 2. In the example shown in FIG. 5, the moving speed of the first moving body 2_1 when moving from the first point P1 to the second point P2 is faster than the moving speed of the second moving body 2_2 when moving from the first point P1 to the second point P2. Therefore, when the second moving body 2_2 receives the recorded content recorded by the first moving body 2_1 for a certain time while moving from the first point P1 to the second point P2 as the distributed content, and plays the distributed content at a constant speed while moving from the first point P1 to the second point P2 (i.e., for the same certain time as the first moving body 2_1), the playback of the distributed content is completed before the second moving body 2_2 arrives at the second point P2. In order to avoid such a situation, the playback speed of the distributed content may be changed according to the moving speed of each moving body 2. A method of changing the playback speed of the distributed content will be described in detail in FIG. 23 described later.

[0065] [Example of content] Next, examples of recorded content that is recorded and distributed content that is distributed and played back will be described.

[0066] Fig. 19A shows an example of recording of content. Fig. 19B shows an example of playing distributed content. In this example, comments are used as an example of content.

[0067] In the present disclosure, content includes content that is recorded instantaneously and does not include differences over time, and content that includes differences over time. A comment is an example of content that is recorded instantaneously and does not include differences over time. Another example of content that does not include differences over time is a still image such as a photograph of a landscape. Examples of content that includes differences over time include video, audio, and the like.

[0068] First, a state in which the first moving body 2_1 records content will be described. FIG. 19A is a diagram for explaining a state in which the first moving body 2_1 records content. FIG. 19A shows a state in which, when the first moving body 2_1 is located at a point where an exhibit can be viewed in an art museum or a museum, a comment made by a passenger is recorded as content. In FIG. 19A, a screen 300 includes a comment input field 301 and a software keyboard 302.

[0069] In the example shown in Fig. 19A, the display 202 (see Fig. 4) of the first moving body 2_1 on which the screen 300 is displayed is assumed to be a transparent display. Therefore, the exhibits can be seen through the screen 300. In Figs. 19A and 19B, the exhibits visible through the screen 300 are indicated by dashed lines. A passenger on the first moving body 2_1 inputs comments such as impressions into a comment input field 301 while viewing the exhibits through or without the screen 300.

[0070] The comment input field 301 is a field for displaying comments such as impressions that passengers of the first moving body 2_1 had after viewing the exhibit 2. The software keyboard 302 is an input means for inputting characters to be displayed in the comment field. The comment input field 301 and the software keyboard 302 are displayed, for example, when a passenger touches a part of the screen 300. The comment input field 301 is displayed, for example, at a position touched by the passenger, and the software keyboard 302 is displayed, for example, at a predetermined position within the screen 300.

[0071] Next, a manner in which the second moving object 2_2 reproduces the distributed content will be described.

[0072] Fig. 19B is a diagram for explaining a state in which the recorded content recorded in Fig. 19A is distributed as a distribution content, and the second moving body 2_2 plays the distribution content. Fig. 19B shows a state in which the recorded content recorded in Fig. 19A is distributed as a distribution content when the second moving body 2_2 is located at a location where the exhibit for which the first moving body 2_1 recorded the content in Fig. 19A can be viewed, and then the distributed distribution content is played.

[0073] 19B, the display of the second moving body 2_2 is also a transmissive display like the first moving body 2_1. Therefore, the exhibit can be seen through the screen 400.

[0074] In the screen 400, a comment field 401 including comments by passengers of the first moving body 2_1 corresponding to the recorded content recorded in FIG. 19A is displayed as distribution content. The display position of the comment field 401 in the screen 400 is preferably approximately the same as the comment input field 301 in the screen 300 shown in FIG. 19A. In the comment "M1: Beautiful!" displayed in the comment field 401 in FIG. 19B, M1 is the identification number (aircraft number) of the first moving body 2_1. In this way, it is preferable that the recorded content and the attribute information of the person or thing who recorded the recorded content are linked and played back. This allows the passenger of the second moving body 2_2 to easily know which passenger on which moving body 2 made the comment.

[0075] In this way, by associating the location information at the time of content recording with the recorded content and playing back the distributed content according to the location of the recorded content, passengers on multiple moving bodies 2 can share the same experience.

[0076] In addition, as in this example, even if the recorded content recorded by the first moving body 2_1 is recorded instantaneously, that is, does not include differences over time, it is desirable that the second moving body 2_2, which reproduces the distributed content corresponding to the recorded content, continuously reproduces the recorded content before and after the recording time. This can prevent a problem that, for example, a passenger on the second moving body 2_2 cannot see the content because the comment column 401 is displayed only for an instant.

[0077] Also, the time when the passenger is typing on the software keyboard 302 may be regarded as the recording start time of the content. In this case, the content is recorded as a video showing the passenger typing the comment, and is distributed as a distribution content including a difference caused by the passage of time from the start of recording, as in another example described later, and is played by the second moving body 2_2. By playing such a distribution content, for example, the passenger of the second moving body 2_2 sees as if the passenger of the first moving body 2_1 is inputting the impression in real time, so that the passenger of the second moving body 2_2 can be given a stronger impression that he / she is sharing the same experience as the passenger of the first moving body 2_1.

[0078] 20A and 20B show another example of recording and playing content. In this example, a video is used as an example of content that includes a difference over time. In other words, the content includes the elapsed time from the start of recording, such as a video or audio.

[0079] The examples shown in Figures 20A and 20B show content in which a first moving body 2_1 and a second moving body 2_2 move along a pre-set tourist route in a tourist spot such as a vast park, including tourist spots such as waterfalls, cherry trees, autumn leaves, flower beds, etc.

[0080] Even when many visitors board the second moving body 2_2 and move around a vast park, the first moving body 2_1 and the plurality of second moving bodies 2_2 move in a chain, preventing them from getting separated from each other, and thus enabling a highly safe group movement that gives the passengers peace of mind.

[0081] In addition, when the first moving body 2_1 and the multiple second moving bodies 2_2 move in a line, the scenery that the passenger wants to see may be in the shadow of the moving body 2 moving in front, making it difficult to see. By recording the scenery as recorded content while the first moving body 2_1 moves at the front, and playing the distribution content corresponding to the recorded content recorded by the second moving body 2_2 moving following the first moving body 2_1, the passenger can see the shaded scenery even if the scenery that he or she wants to see is in the shadow of the moving body 2 moving in front.

[0082] In the examples shown in Fig. 20A and Fig. 20B, it is assumed that the display 202 of the moving body 2 is not a transmissive type. Fig. 20A is a diagram illustrating the field of view of a passenger of the first moving body 2_1 during content recording. Fig. 20A shows a tree 500 as an example of a landscape visible to a passenger of the first moving body 2_1, and the display 202 displaying an image 600 of the tree 500.

[0083] On the other hand, Fig. 20B is a diagram illustrating the field of view of a passenger of the second moving body 2_2 when the distribution content corresponding to the recorded content recorded in Fig. 20A is played back. In Fig. 20B, it is assumed that the passenger of the second moving body 2_2 cannot see the tree 500 because it is hidden by the moving body 2 in front. However, since the display 202 displays an image 600 when the distribution content corresponding to the recorded content recorded in Fig. 20A is played back, the passenger can experience how the tree 500 looks. This allows the passenger of the first moving body 2_1 and the passenger of the second moving body 2_2 to have a common experience.

[0084] 20A and 20B, it is assumed that the first moving body 2_1 and the second moving body 2_2 move in a linked manner. However, this is not limited to this, and even if the first moving body 2_1 and the second moving body 2_2 move apart from each other and along the same route, similar content recording and playback can be performed.

[0085] Also, the timing of recording by the first moving body 2_1 and the timing of playback by the second moving body 2_2 may be significantly different. For example, the first moving body 2_1 may record cherry blossoms blooming in spring as recorded content, and when the moving body 2 travels along the route in autumn, it may play back the distributed content corresponding to the recorded content showing the cherry blossoms blooming while moving among the trees with autumn leaves. Even in such a case, the passengers of the moving body 2 may share the same experience.

[0086] As another example of the content including the difference caused by the passage of time from the start of recording, for example, the voice of the passenger who looks at the exhibit may be recorded as the content. In this case, a microphone provided in the first moving body 2_1 records the voice of the passenger. As a further developed example, for example, the passenger of the first moving body 2_1 may be a guide at an art museum or a museum, and the recorded content may be a voice of a guide to the exhibit. In such a case, the first moving body 2_1 carrying the guide moves within the museum, and the guide's guide at a point where the exhibit can be viewed is recorded as the recorded content. Then, the second moving body 2_2 carrying the visitors moves along the trajectory of the first moving body 2_1, and the distributed content corresponding to the recorded content including the guide's guide at a point where the exhibit can be viewed is played back. As a result, a large number of visitors can have a common experience of viewing the same guide at a point where the same exhibit can be viewed by boarding multiple second moving bodies 2_2.

[0087] The recorded and played content may be a combination of a plurality of the above-mentioned various content examples. For example, in a situation of a tour of a stadium where a sports event is to be watched, the moving body 2 outputs sports-related information to the display of the playback device 24 while playing a guide voice from the speaker of the playback device 24. In this way, the recorded and played content may be a combination of content recorded instantaneously and not including a difference caused by the passage of time from the start of recording, and content including a difference caused by the passage of time from the start of recording. Also, in the same situation of a tour of a stadium as described above, the moving body 2 may play a guide voice from the speaker of the playback device 24 while displaying the current stadium scene and a practice scene of a player previously recorded at the same stadium, superimposed on each other, on the display of the playback device 24.

[0088] [Processing content] Hereinafter, details of the processing contents of the information processing system 100 for realizing the movement of the moving object 2 and the reproduction of the content as described above will be described with reference to FIG.

[0089] In step S1, the first moving body 2_1 starts moving along a predetermined route and starts recording of the content. Note that, in the example shown in Fig. 21, a case will be described in which the movement of the first moving body 2_1 and the content recording start almost simultaneously, but, for example, the movement may start before the content recording, or the content recording may start before the movement.

[0090] As described above, the recorded content recorded by the first moving object 2_1 includes content such as comments (text), still images, videos, and audio. When the recorded content is recorded instantaneously, such as comments or still images, and does not include differences over time from the start of recording, time information indicating the elapsed time from the start of recording is added. When the recorded content is a video including differences over time from the start of recording and the video is made up of multiple frames, frame information indicating the number of frames from the start of recording may be included instead of time information.

[0091] Furthermore, the first moving body 2_1 generates its own position information while recording the content, and stores it in association with the recorded content. More specifically, the first moving body 2_1 generates first position information indicating the position of the first moving body 2_1 while recording the content, and stores it in the storage unit 27 in association with time information or frame information included in the recorded content. The first position information and the time information or frame information make it easy to identify which part of the recorded content was recorded when the first moving body 2_1 was at which position within a specified route.

[0092] Moreover, the first moving body 2_1 generates first speed information indicating the moving speed of the first moving body 2_1 when it moves, and stores the first speed information in association with the time information of the recorded content in the storage unit 27. This makes it possible to easily identify the speed of the first moving body 2_1 while the content is being recorded.

[0093] Furthermore, the first moving body 2_1 generates first direction information indicating the moving direction of the first moving body 2_1 when it moves, and stores the information in association with time information of the recorded content in the storage unit 27. This makes it possible to easily identify the moving direction of the first moving body 2_1 while the content is being recorded.

[0094] In step S2, the first moving body 2_1 transmits to the information processing device 1 the recorded content, first position information indicating the position of the first moving body 2_1 while recording the recorded content, first speed information indicating the moving speed of the first moving body 2_1 while recording the recorded content, and first direction information indicating the moving direction of the first moving body 2_1 while recording the recorded content.

[0095] In step S2, the first moving body 2_1 may transmit the recorded content recorded up to that point at any time, or may transmit a certain amount of recorded content all at once after recording of the content has progressed to a certain extent. An example of transmitting recorded content at any time is a case where recorded content such as a moving image generated for each frame is transmitted for each frame. Also, an example of transmitting a certain amount of recorded content all at once is a case where a series of recorded contents recorded at one point on a specified route is transmitted all at once when recording at that point is completed.

[0096] In step S3, the information processing device 1 receives the recorded content, the first position information, the first speed information, and the first direction information, and stores them in the storage unit 13 in association with each other. Specifically, the information processing device 1 stores the first position information as recording position information indicating the position where the first moving body 2_1 performed recording, and associates it with the recorded content. Furthermore, the information processing device 1 stores the first speed information as recording speed information indicating the moving speed of the first moving body 2_1 while performing recording, and associates it with the recorded content. Furthermore, the information processing device 1 stores the first direction information as recording direction information indicating the moving direction of the first moving body 2_1 while performing recording, and associates it with the recorded content. By repeating this process, the storage unit 13 accumulates a series of contents recorded up to that point in time, and the recording position information, recording speed information, and recording direction information associated with the contents.

[0097] On the other hand, in step S4, the second moving body 2_2 starts moving. When there are multiple second moving bodies 2_2, the multiple moving bodies 2_2 may start moving one by one, for example, with a necessary inter-vehicle distance. In Fig. 21, the operation when there is one second moving body 2_2 is shown.

[0098] In step S5, the second moving object 2_2 generates second position information indicating its own position, second speed information indicating its own moving speed, and second direction information indicating its own moving direction, and transmits them to the information processing device 1.

[0099] In step S6, the information processing device 1 receives second position information indicating the current position of the second moving object 2_2, second speed information indicating the moving speed, and second direction information indicating the moving direction.

[0100] In step S7, the information processing device 1 transmits distribution content to the second moving body 2_2 based on the recorded content, recording position information, recording speed information, and recording direction information recorded by the first moving body 2_1 stored in the storage unit 13 in step S3, and the second position information, second speed information, and second direction information received in step S6. When a plurality of recorded contents and their associated data are stored in the storage unit 13, the recorded content associated with recording position information that approximately matches the second position information may be determined as the distribution content to be distributed to the second moving body 2_2. Details of the playback control of the distribution content for the second moving body 2_2 in this step S7 will be described later.

[0101] In step S8, the second moving object 2_2 starts playing the distributed content based on the playback control by the information processing device 1 in step S7.

[0102] In step S9, the first moving object 2_1 finishes recording and moving the content. After that, in step S10, the second moving object 2_2 finishes playing and moving the distributed content.

[0103] The above describes the operation of the information processing system 100. With such an operation, the recorded content recorded by the first moving body 2_1 can be reproduced as distribution content at the same position in the second moving body 2_2 moving along the same route as the first moving body 2_1. This allows a person on the second moving body 2_2 to experience the same scenery, view, or scene as seen by a person on the first moving body 2_1, and allows the same experience to be shared among people appearing on multiple second moving bodies 2_2.

[0104] [Processing of information processing device 1] Next, with reference to FIG. 22, a process performed by the information processing device 1 in the operation of the information processing system 100 shown in FIG. 21 will be described in detail.

[0105] In step S11, the information processing device 1 receives the recorded content, the first position information, the first speed information, and the first direction information from the first moving object 2_1. Note that the recorded content is the content recorded by the first moving object 2_1, as described above.

[0106] In step S12, the information processing device 1 treats the first position information, first speed information, and first direction information received in step S11 as recording position information indicating the position where the first moving body 2_1 recorded, recording speed information indicating the moving speed of the first moving body 2_1 while recording, and recording direction information indicating the moving direction of the first moving body 2_1 while recording, and associates them with the recorded content.

[0107] In step S13, the information processing device 1 stores in the storage unit 27 the recorded content associated in step S12, the recording position information, the recording speed information, and the recording direction information.

[0108] In step S14, the information processing device 1 receives the second position information, the second speed information, and the second direction information from the second moving object 2_2.

[0109] In step S15, the information processing device 1 determines the content (distribution content) to be distributed to the second moving body 2_2 from among the recorded contents stored in the storage unit 27 based on the second position information, the second speed information, and the second direction information. As described above, the distribution content is the recorded content stored in the information processing device 1 and is the content to be distributed to the second moving body 2_2 for playback.

[0110] How the information processing device 1 determines the distribution contents to be distributed to the second moving object 2_2 from among the recorded contents will be described in detail later with reference to FIG.

[0111] In step S16, the information processing device 1 generates playback speed information that specifies the playback speed of the distribution content based on the second position information, the second speed information, the second direction information, and the distribution content determined in step S15. A method for determining the playback speed of the distribution content will be described in detail later with reference to FIG.

[0112] In step S17, the information processing device 1 transmits the distribution content determined in step S15 and the playback speed information determined in step S16 to the second moving body 2_2. As a result, when the second moving body 2_2 arrives at the same position as the first moving body 2_1 was at while recording the content, the second moving body 2_2 can play back the distribution content of the same scene as the recorded content recorded at that position. Also, the second moving body 2_2 can play back the distribution content at a playback speed that matches its own moving speed.

[0113] [How content and playback speed are determined] Next, with reference to FIG. 23, a method for determining the distribution content (corresponding to step S15 in FIG. 22) and a method for determining the playback speed of the distribution content (corresponding to step S16 in FIG. 22) in information processing device 1 will be described in detail.

[0114] In step S21, the information processing device 1 extracts, from the recording position information accumulated in the storage unit 13, recording position information indicating the position of the first moving object 2_1 at the time of recording, the distance from which to the current position of the second moving object 2_2 is less than a first threshold value α1. The magnitude of the first threshold value α1 is appropriately set, for example, by an administrator of the information processing system 100. The second position information indicating the current position of the second moving object 2_2 is received by the information processing device 1 in step S14 of FIG.

[0115] For example, when the current location of the second moving body 2_2 indicated by the second location information is the second point P2 shown in FIG. 5, the information processing device 1 extracts recording location information in which the location of the first moving body 2_1 is the second point P2 from the recording location information stored in the memory unit 13.

[0116] Furthermore, when the current location of the second moving body 2_2 indicated by the second location information is between the first location P1 and the second location P2 shown in FIG. 5, the information processing device 1 extracts, from the recording location information stored in the memory unit 13, recording location information in which the location of the first moving body 2_1 is between the first location P1 and the second location P2.

[0117] This makes it possible to extract recorded position information indicating the position of the first moving body 2_1 which coincides with the current position of the second moving body 2_2.

[0118] Next, in step S22, the information processing device 1 extracts, from the recording position information extracted in step S21, recording position information associated with a recording movement direction indicating a movement direction in which an angle formed with the current movement direction of the second moving body 2_2 is less than a predetermined second threshold value α2. The second direction information indicating the current movement direction of the second moving body 2_2 is received by the information processing device 1 in step S14 of FIG.

[0119] While the first moving body 2_1 and the second moving body 2_2 are moving along a predetermined route, they may pass through the same position while facing completely different directions. In such a case, the scenery seen from the first moving body 2_1 and the scenery seen from the second moving body 2_2 are completely different, so if the recorded content recorded by the first moving body 2_1 is distributed to the second moving body 2_2 as a distribution content even though they are at the same position, the person riding on the first moving body 2_1 and the person riding on the second moving body 2_2 cannot share the same experience. In step S22, by extracting recording position information in which the angle between the moving direction of the first moving body 2_1 and the moving direction of the second moving body 2_2 is less than the second threshold value α2, it is possible to eliminate recording position information in which the moving direction is completely different just because it happens to be the same position as the current position of the second moving body 2_2.

[0120] Next, in step S23, the information processing device 1 extracts from the storage unit 13 the recorded contents associated with the recording location information extracted in step S22. For example, when the location of the first moving body 2_1 indicated in the recording location information extracted in step S22 is the second point P2 shown in Fig. 5, a series of recorded contents recorded by the first moving body 2_1 at the second point P2 is extracted. Also, when the location of the first moving body 2_1 indicated in the recording location information extracted in step S22 is between the first point P1 and the second point P2, a series of recorded contents recorded while the first moving body 2_1 moves from the first point P1 to the second point P2 is extracted.

[0121] Next, in step S24, the information processing device 1 determines the playback speed when transmitting the recorded content to the second moving body 2_2 to be played back as distribution content, based on the speed of the first moving body 2_1 and the speed of the second moving body 2_2 indicated by the recording speed information associated with the recording location information extracted in step S22.

[0122] A specific example will be given for explanation. It is assumed that the first moving body 2_1 moves at a constant speed V1 from the first point P1 to the second point P2 shown in Fig. 5 while recording the recorded content. It is also assumed that the second moving body 2_2 is currently moving at a constant speed V2 from the first point P1 to the second point P2. In this case, the time required for the second moving body 2_2 to move from the first point P1 to the second point P2 is V1 / V2 times the time required for the first moving body 2_1 to move from the first point P1 to the second point P2.

[0123] When a series of recorded contents recorded while the first moving body 2_1 is moving from the first point P1 to the second point P2 is played back as distribution contents in the second moving body 2_2, it is desirable that the playback is completed while the second moving body 2_2 is moving from the first point P1 to the second point P2. In this case, by setting the playback speed of the distribution contents in the second moving body 2_2 to V2 / V1, the playback of the distribution contents can be completed while the second moving body 2_2 is moving from the first point P1 to the second point P2.

[0124] When the moving speed V2 of the second moving body 2_2 is smaller than the moving speed V1 of the first moving body 2_1, the time required for the second moving body 2_2 to move from the first point P1 to the second point P2 is longer than that of the first moving body 2_1. In such a case, the information processing device 1 determines the playback speed of the distributed content to be slower than the normal speed. On the other hand, when the moving speed V2 of the second moving body 2_2 is greater than the moving speed V1 of the first moving body 2_1, the time required for the second moving body 2_2 to move from the first point P1 to the second point P2 is shorter than that of the first moving body 2_1. In such a case, the information processing device 1 determines the playback speed of the distributed content to be faster than the normal speed.

[0125] In the above example, a case was described in which the first moving body 2_1 and the second moving body 2_2 move at a constant speed, but if the movement is not at a constant speed, the playback speed of the distributed content can be appropriately adjusted, for example, by using the average movement speed between points.

[0126] As a method for changing the playback speed in the second moving body 2_2, a known technique can be adopted. For example, when the distribution content is a moving image generated for each frame, the playback speed in the second moving body 2_2 can be suitably changed by adjusting the frame rate according to the determined playback speed.

[0127] For example, if the content being distributed is a moving image or audio, making the playback speed too fast may result in a situation where it is difficult to understand what is being displayed or what is being said. To avoid such a situation, an upper limit on the playback speed may be set in advance.

[0128] The distribution contents that the information processing device 1 has decided to distribute as described above, and the reproduction speed information are then transmitted to the second moving object 2_2 in step S17 of FIG.

[0129] [effect] According to the information processing method, information processing system, and information processing device disclosed herein, for example, in a facility such as a museum or art gallery, an experience (recorded content) when one moving body views an exhibit can be distributed as distribution content to another moving body when the other moving body comes in front of the same exhibit, and can be played back. Therefore, a person who rides on or travels with the other moving body can share the experience of the one moving body viewing the exhibit.

[0130] Furthermore, according to the information processing method, information processing system, and information processing device disclosed herein, it is possible to suitably control the playback of distributed content in multiple moving bodies so that multiple people can share the same experience. As a result, for example, when the same content as that of one moving body is played back at the same timing and playback speed in another moving body located at a different position from that of the other moving body, playback of the content may start before a person riding on or accompanying the other moving body has arrived in front of a certain exhibit, or playback of the content may end while the other moving body is moving, thereby preventing a situation in which a person riding on the other moving body cannot share the same experience as a person riding on or accompanying the one moving body.

[0131] [Variations] In the above-described embodiment, an electric wheelchair equipped with a playback device is given as an example of the moving body 2. However, the moving body of the present disclosure may not have a function of moving by itself, and may be, for example, a device that can move by being carried by a person. Specifically, the moving body of the present disclosure may be a mobile terminal device such as a smartphone or a tablet terminal. In addition, all of the multiple moving bodies may be the same type of device, or multiple types of devices may be mixed. That is, the moving body that records the content may be an electric wheelchair, and the recorded content recorded by the electric wheelchair may be reproduced as distribution content by a mobile terminal device that moves along the same route as the electric wheelchair. In addition, multiple types of devices may be mixed in a group of moving bodies 2 moving in the same space. For example, the recorded content recorded by the electric wheelchair may be distributed as distribution content to the following electric wheelchair and to a tablet terminal carried by a person moving nearby, and may be reproduced.

[0132] In the above-described embodiment, as shown in Fig. 3, the mobile body 2 is equipped with both the recording device 23 and the playback device 24, but the mobile body 2 may be equipped with either the recording device 23 or the playback device 24. In this case, the mobile body 2 which is a recording mobile body equipped only with the recording device 23 and which only records the content moves first, and the mobile body 2 which is a playback mobile body equipped only with the playback device 24 and which only plays back the content moves after.

[0133] In the above-described embodiment, an example has been described in which the location information indicating the location of the moving object 2 is acquired by the location information acquisition unit 25 and received by the information processing device 1. However, the location information indicating the location of the moving object 2 may be acquired directly by the information processing device 1. For example, when a camera installed at a specific point captures the moving object 2, the information processing device 1 may calculate location information indicating that the moving object 2 is at the point based on the installation location and angle of view of the camera. In addition, such calculation of location information may be performed by, for example, a monitoring system that manages the camera, and the information processing device 1 may receive location information indicating the location of the moving object 2 from the monitoring system. In this way, the location information indicating the location of the moving object 2 may be acquired or received by the information processing device 1.

[0134] In the above-described embodiment, an example has been described in which the speed information acquisition unit 28 acquires the speed information indicating the moving speed of the moving body 2 and the information processing device 1 receives it. However, the information processing device 1 may directly acquire the speed information indicating the moving speed of the moving body 2. For example, the information processing device 1 acquires the speed information of the moving body 2 by generating the speed information based on the position of the moving body 2 and a change in the position of the moving body 2 over time. In this way, the speed information indicating the moving speed of the moving body 2 may be acquired or received by the information processing device 1.

[0135] In the above-described embodiment, an example has been described in which the direction information acquisition unit 29 acquires the direction information indicating the moving direction of the moving body 2 and the information processing device 1 receives it. However, the information processing device 1 may directly acquire the direction information indicating the moving direction of the moving body 2. For example, the information processing device 1 acquires the direction information of the moving body 2 by generating the information based on the position of the moving body 2 and a change in the position of the moving body 2 over time. In this way, the direction information indicating the moving direction of the moving body 2 may be acquired or received by the information processing device 1.

[0136] In the above-described embodiment, an example has been described in which the multiple moving bodies 2 include a leading moving body and other moving bodies that move following the leading moving body. The other moving bodies may move along exactly the same route as the leading moving body, or may move slightly off the route within a preset allowable range. In this case, the other moving bodies are allowed to perform autonomous actions such as avoiding small obstacles, improving safety. In addition, when the other moving bodies move along a route slightly off the route traveled by the leading moving body in this way, the first threshold value α1 described in step S21 of FIG. 23 can be adjusted to suitably play back the distributed content in the other moving bodies.

[0137] Also, for example, when another moving body enters midway along a predetermined route, the other moving body can be made to start playing back the distributed content from the middle by taking the following measures. In the above-described embodiment, the recorded content recorded by the first moving body 2_1 includes time information indicating the time elapsed since the start of recording (step S1 in FIG. 21). Since the content is associated with recording position information indicating the position of the first moving body 2_1 while recording the content, the time information makes it easy to identify which part of the recorded content was recorded when the first moving body 2_1 was at which position along the predetermined route.

[0138] Therefore, when the second moving body 2_2 enters from the middle of the predetermined route, it is easy to identify which part of the recorded content was recorded when the first moving body 2_1 was at the same position as the current position of the second moving body 2_2 indicated by the second position information. As a result, when the second moving body 2_2 enters from the middle of the predetermined route, it is possible to cause the second moving body 2_2 to play back from the middle of the recorded content recorded by the first moving body 2_1.

[0139] In the above-described embodiment, an example has been described in which the recording or playback of content is continued from the start of the movement of the moving object 2 to the end of the movement. However, there may be a time when the moving object 2 moves without recording or playing back content. For example, the present disclosure also includes a mode in which, in the example shown in FIG. 5, the recording or playback of content is performed while the moving object 2 is stopped at the second point P2, but the recording or playback of content is not performed while the moving object is moving from the second point P2 to the third point P3.

[0140] In the above-described embodiment, the information processing device 1 controls the moving object 2. However, for example, any one or all of the multiple moving objects 2 may have the functions of the information processing device 1 of the above-described embodiment. In this case, the moving object 2 having the functions of the information processing device 1 acquires the recorded content and its related data from the moving object 2 that recorded the content, associates and stores them, and plays back the recorded content on its own basis based on its own location information, etc. Alternatively, the moving object 2 having the functions of the information processing device 1 distributes the recorded content to other moving objects 2 based on location information, etc. acquired from the other moving objects 2. In this case, the information processing system 100 does not need to include the information processing device 1, and the operating costs of the information processing system 100 can be reduced.

[0141] In the above-described embodiment, the mobile object 2 that received the distributed content controlled the playback of the distributed content. However, for example, the information processing device 1 may control the playback of the distributed content in the mobile object 2 in part or in whole. Specifically, the information processing device 1 uses the location information received from the mobile object 2 to determine which recorded content is to be played as the distributed content, how many seconds have elapsed since the start of the recorded content to be played, at what playback speed, and the like, and remotely controls the playback device 24 of the mobile object 2 based on the determined contents. [Industrial Applicability]

[0142] The present disclosure is useful in a system for recording and playing back content in multiple mobile objects. [Explanation of symbols]
