DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <Embodiment> Hereinafter, embodiments of the system, method, and program according to the present disclosure will be described with reference to the drawings. The configurations of the embodiments described below, and the actions and effects brought about by the configurations, are merely examples, and are not limited to the contents described below.

[0014] In addition, in the following, ordinal numbers such as "first" and "second" are used as necessary, but these ordinal numbers are used for convenience of identification and do not indicate a particular priority order.

[0015] FIG. 1 is an exemplary schematic diagram showing a configuration of a system 100 according to an embodiment.

[0016] As shown in FIG. 1, a system 100 according to the embodiment includes an acquisition unit 110 and an output unit 120.

[0017] The acquisition unit 110 acquires accident information indicating the circumstances of a traffic accident that has occurred. The accident information includes various data such as device data (e.g., acceleration data, GPS data, etc.) acquired from various devices such as a drive recorder mounted on a vehicle involved in the traffic accident, road information, map data, and weather data of the location where the traffic accident has occurred.

[0018] The output unit 120 outputs explanatory video for explaining information about the traffic accident indicated in the accident information to the parties involved in the traffic accident. In the embodiment, the information about the traffic accident is explained to the parties involved in a manner that is easier for the parties involved to understand, not verbally, but by using explanatory video.

[0019] More specifically, the output unit 120 determines the fault ratio of each of the parties in the traffic accident (e.g., the first driver and the second driver) based on the accident information acquired by the acquisition unit 110 and the reference information recorded in the reference information database 121. The fault ratio is a numerical value that represents the degree of responsibility of the parties, for example, in a percentage. The reference information is information on multiple legal precedents regarding traffic accidents that have occurred in the past, which serves as the basis for determining the fault ratio.

[0020] The output unit 120 then outputs the determined fault ratio as an inclusion in the explanation video. Furthermore, the output unit 120 can output information to be described below in addition to the fault ratio as an inclusion in the explanation video.

[0021] For example, the output unit 120 may output, in the explanatory video, at least one reference video showing the situation of a traffic accident similar in type to the traffic accident indicated in the accident information acquired by the acquisition unit 110. The output unit 120 extracts a reference video to be included in the explanatory video from a reference video database 122 in which a plurality of reference videos showing the situations of a plurality of types of traffic accidents, which have been created in advance, are recorded, based on the accident information acquired by the acquisition unit 110 (for example, the above-mentioned acceleration data, GPS data, etc.).

[0022] Furthermore, the output unit 120 may output a correction factor that may be applied to correct the above-mentioned fault ratio, further included in the explanatory video. The correction factor is a numerical value that is added to or subtracted from the numerical value representing the above-mentioned fault ratio, depending on the type of the traffic accident. Depending on the type of the traffic accident, the correction factor may not be applied. The correction factor is linked to each reference video in the reference video database 122. Note that, hereinafter, the fault ratio before the correction factor is applied may be expressed as the basic fault ratio.

[0023] Furthermore, the output unit 120 may output an interface for receiving input of the parties' intentions (whether they agree or not) regarding the basic fault ratio and the correction factors explained in the explanatory video, by further including the interface in the explanatory video. Also, the output unit 120 may output a video recorded by a drive recorder of the parties' vehicle, by further including the video in the explanatory video.

[0024] Note that specific examples of how the above-mentioned various types of information are explained in the explanatory video will be explained later, so further explanation will be omitted here.

[0025] Based on the above configuration, the system 100 according to the embodiment operates in the manner shown in FIG.

[0026] FIG. 2 is an exemplary schematic block diagram showing the flow of processing executed in the system 100 according to the embodiment.

[0027] 2, in the embodiment, first, in step S201, the acquisition unit 110 acquires accident information. Then, in step S202, the output unit 120 compares the accident information acquired in step S201 with reference information recorded in the reference information database 121, and acquires reference information related to a traffic accident similar to the traffic accident indicated by the accident information.

[0028] Then, in step S203, the output unit 120 determines the fault ratio (basic fault ratio) of the parties involved in the traffic accident indicated in the accident information acquired in step S201, based on reference information regarding traffic accidents similar to the traffic accident indicated in the accident information.

[0029] Then, in step S204, the output unit 120 extracts from the reference video database 122 at least one reference video that shows a situation of a traffic accident similar in type to the traffic accident indicated in the accident information acquired in step S201.

[0030] Then, in step S205, the output unit 120 refers to the reference video database 222 and determines the correction element associated with the reference video extracted in step S204.

[0031] Then, in step S206, the output unit 120 outputs the various information acquired in steps S203 to S205 by including it in the explanatory video. The output explanatory video is provided to the parties involved in the traffic accident. Then, the processing ends. In this manner, in the embodiment, information related to the traffic accident is explained to the parties involved in a manner that is easier for the parties to understand, not verbally, but by using the explanatory video.

[0032] Hereinafter, specific examples of various images displayed in the explanation moving image will be described with reference to FIGS.

[0033] FIG. 3 is an illustrative schematic diagram showing an example of an image that is displayed first in the explanation moving image according to the embodiment.

[0034] As shown in Fig. 3, in the explanatory video, first, image 310 is displayed as a title screen of the entire explanatory video. Then, image 320 is displayed including area 322 in which a list of items explained in the explanatory video is displayed. Note that images 310 and 320 can transition to each other in response to operations by a user (a person involved in the traffic accident who is viewing the explanatory video) on operation interfaces 311 and 321 displayed at the bottom of each image. Then, when operation interface 321 of image 320 is operated, image 410 shown in Fig. 4 can be transitioned to.

[0035] FIG. 4 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 3 in the explanatory moving image according to the embodiment.

[0036] In the example shown in FIG. 4, first, image 410 is displayed as a title screen indicating that an explanation of fault ratio will begin. Then, image 420 is displayed displaying an explanation of the meaning of the term fault ratio. Then, image 430 is displayed displaying an explanation of how fault ratio is determined. Note that images 410, 420, and 430 can transition to each other in response to user operations on operation interfaces 411, 421, and 431 displayed below each image. Then, when operation interface 431 of image 430 is operated, it is possible to transition to image 510 shown in the next FIG. 5.

[0037] FIG. 5 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 4 in the explanatory moving image according to the embodiment.

[0038] In the example shown in FIG. 5, first, image 510 is displayed as a title screen indicating that an explanation of the basic negligence ratio and the correction factor will start. Then, image 520 is displayed in which an explanation showing the relationship between the basic negligence ratio and the correction factor is displayed. Then, image 530 is displayed in which a case example 532 of the basic negligence ratio is displayed together with an example image 533, and image 540 is displayed in which a case example 542 of the correction factor is displayed together with an example image 543. Note that images 510, 520, 530, and 540 can transition to each other according to user operations on operation interfaces 511, 521, 531, and 541 displayed below each image. Then, when operation interface 541 of image 540 is operated, it can transition to image 610 shown in the next FIG. 6.

[0039] FIG. 6 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 5 in the explanatory moving image according to the embodiment.

[0040] In the example shown in FIG. 6, first, image 610 is displayed as a title screen indicating that the explanation of the fault ratio determined by system 100 for the traffic accident (hereinafter, for simplification, may be referred to as the current traffic accident) caused by the party viewing the explanatory video is to begin. Then, image 520 is displayed in which the fault ratio determined by system 100 is displayed divided into a basic fault ratio and a correction factor. Image 520 includes an area 622 in which three items 623 to 625 are displayed. Item 623 displays the respective fault ratios (after correction factors have been applied) of the party viewing the explanatory video and the other party, item 624 displays the basic fault ratio and correction factors that are the basis for calculating the fault ratio displayed in item 623 in a classified form, and item 625 displays the fault ratio calculated based on the basic fault ratio and correction factors displayed in item 624 (the same as the fault ratio displayed in item 623). The images 610 and 620 can transition to each other in response to user operations on operation interfaces 611 and 621 displayed below the images 610 and 620. When the operation interface 621 of the image 620 is operated, the image 620 can transition to the image 710 shown in the next FIG.

[0041] FIG. 7 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 6 in the explanatory moving image according to the embodiment.

[0042] In the example shown in FIG. 7, an image 710 is displayed as a title screen indicating that a more detailed explanation of the basic fault ratio displayed in the example shown in FIG. 6 is to begin. Then, an image 720 is displayed in which an item 723 indicating the numerical value of the basic fault ratio of the current traffic accident is displayed together with a moving image 722. The moving image 722 displayed in the image 720 is a reference moving image, that is, a moving image showing the situation of a traffic accident similar in type to the current traffic accident, extracted by the system 100 from the reference moving image database 122. Note that the images 710 and 720 can transition to each other in response to the user's operation on the operation interfaces 711 and 721 displayed below each image. Then, when the operation interface 721 of the image 720 is operated, the image can transition to the image 810 shown in the next FIG. 8.

[0043] FIG. 8 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 7 in the explanatory moving image according to the embodiment.

[0044] In the example shown in FIG. 8, first, an image 810 is displayed as a title screen indicating that a more detailed explanation of the correction element displayed in the example shown in FIG. 6 is to be started. Then, images 820 and 830 including explanations of the correction element of the current traffic accident are displayed. In the image 820, an item 823 indicating the numerical value of the correction element in the current traffic accident is displayed together with a moving image 822, and in the image 830, an item 833 indicating an explanation of why the correction element can be applied in the current traffic accident is displayed together with a moving image 832. The moving images 822 and 832 are the same moving images, and are reference moving images linked to the correction element in the current traffic accident. Note that the images 810, 820, and 830 can be mutually transitioned according to the user's operation on the operation interfaces 811, 821, and 831 displayed below each image. Then, when the operation interface 831 of the image 830 is operated, the image can be transitioned to the image 910 shown in the next FIG. 9.

[0045] FIG. 9 is an illustrative schematic diagram showing an example of an image displayed following the image shown in FIG. 8 in the explanatory moving image according to the embodiment.

[0046] 9, first, image 910 is displayed as a title screen indicating that confirmation of the intention of the parties regarding the fault ratio (the fault ratio explained in the various images shown in FIGS. 6 to 8 above) determined by system 100 will begin. Then, in response to an operation performed by an operation interface 911 displayed below image 510, image 920 is displayed, which includes an item 921 displaying the fault ratio of the current traffic accident, and an interface 922 for receiving an input operation of the intention of the parties regarding the fault ratio displayed in item 921 (agreement, disagreement, or request for contact from a person in charge at the insurance company).

[0047] The explanatory video according to the embodiment may include information other than the information displayed in the images shown in Figures 3 to 9, as long as the information is useful for explaining information related to the current traffic accident. For example, in the embodiment, in order to provide a more detailed explanation to the parties involved, video from a drive recorder of the vehicle of the parties involved in the current traffic accident may be included in the explanatory video.

[0048] As described above, the system 100 according to the embodiment includes the acquisition unit 110 and the output unit 120. The acquisition unit 110 acquires accident information indicating the situation of a traffic accident caused by a first driver and a second driver. The output unit 120 outputs the respective fault ratios of the first driver and the second driver in the traffic accident indicated by the accident information, which are determined based on the accident information acquired by the acquisition unit 110 and reference information including legal precedents related to traffic accidents that have occurred in the past, in an explanatory video for explaining information related to the traffic accident indicated by the accident information to the first driver or the second driver.

[0049] According to the above configuration, the fault ratio can be explained to the parties involved in the traffic accident (the first driver or the second driver) in a more understandable manner using explanatory moving images instead of verbally. This can further improve the ease of understanding of the explanation of information related to the traffic accident given to the parties involved.

[0050] Finally, a hardware configuration of the system 100 according to the above-mentioned embodiment will be described. The system 100 according to the embodiment is configured to include an information processing device 1000 having a hardware configuration equivalent to that of a general computer, for example, as shown in the following Fig. 10.

[0051] FIG. 10 is an exemplary schematic block diagram showing a hardware configuration of an information processing device 1000 constituting a system 100 according to an embodiment.

[0052] 10, the information processing device 1000 includes a processor 1010, a memory 1020, a storage 1030, an input / output interface (I / F) 1040, and a communication interface (I / F) 1050. These pieces of hardware are connected to a bus 1060.

[0053] The processor 1010 is configured as, for example, a CPU (Central Processing Unit), and controls the overall operation of each part of the information processing device 1000 .

[0054] Memory 1020 includes, for example, Read Only Memory (ROM) and Random Access Memory (RAM), and provides volatile or non-volatile storage of various data such as programs executed by processor 1010, and provides a working area for processor 1010 to execute programs.

[0055] The storage 1030 includes, for example, a hard disk drive (HDD) or a solid state drive (SSD), and stores various types of data in a non-volatile manner.

[0056] The input / output interface 1040 controls the input of data to the information processing device 1000 from input devices such as a touch panel, keyboard, and mouse, and the output of data from the information processing device 1000 to output devices such as a display and speaker.

[0057] The communication interface 1050 enables the information processing device 1000 to communicate with other devices.

[0058] The functional configuration (see FIG. 1) of the system 100 according to the embodiment is realized as a group of functional modules by cooperation between hardware and software as a result of the processor 1010 executing a program previously stored in the memory 1020 or the storage 1030. However, in the embodiment, some or all of the group of functional modules shown in FIG. 1 may be realized only by hardware such as a dedicated circuit. Furthermore, in the embodiment, the group of functional modules shown in FIG. 1 may be realized in a distributed manner by a plurality of information processing devices 1000.

[0059] It should be noted that the above-mentioned programs do not necessarily need to be stored in advance in the memory 1020 or the storage 1030. For example, the above-mentioned programs may be provided as a computer program product recorded in an installable or executable format on a computer-readable medium, such as various magnetic disks such as a flexible disk (FD) or various optical disks such as a digital versatile disk (DVD).

[0060] The above-mentioned program may be provided or distributed via a network such as the Internet. In other words, the above-mentioned program may be provided in a state where it is stored on a computer connected to a network such as the Internet and is available for download via the network.

[0061] <Modification> In the above-mentioned embodiment, a configuration is exemplified in which, based on the accident information (especially acceleration data, GPS data, etc.) acquired by the acquisition unit 110, a reference video showing the situation of a traffic accident similar in type to the traffic accident indicated by the accident information is extracted from the reference video database 122, and the extracted reference video is included in the explanatory video and output. However, as a modified example, a re-enacted video reproducing the situation of the traffic accident indicated by the accident information is created separately from the reference video, and the created re-enacted video is included in the explanatory video together with the reference video and output. In addition to the accident information (acceleration data, GPS data, etc.) acquired by the acquisition unit 110, various types of video such as video recorded by a drive recorder of the vehicle that caused the accident and video acquired from a surveillance camera installed in the vicinity of the location where the traffic accident occurred can be used to create the re-enacted video. In addition, information at the time of the traffic accident obtained from the person who caused the traffic accident can also be used to create the re-enacted video. The re-enacted video is created, for example, by having the parties involved view video that is automatically created by system 100 based on information such as accident information and various types of video footage so as to objectively recreate the traffic accident from the perspective of the parties involved or a third party, and then making appropriate corrections to the video based on feedback from the parties involved.

[0062] In addition, in the above-mentioned embodiment, a configuration is exemplified in which both the fault ratio and the reference video are included in the explanatory video and output. However, it is not necessarily necessary to include the fault ratio in the explanatory video. The configuration in which only the reference video is included in the explanatory video and output can also achieve the same effect as the above-mentioned embodiment, that is, the ease of understanding of the explanation of the information on the traffic accident given to the parties involved is improved compared to the conventional technology in which the explanation of the information on the traffic accident is given orally.

[0063] Although the embodiments and modifications of the present disclosure have been described above, these embodiments and modifications are presented as examples and are not intended to limit the scope of the invention. These new embodiments and modifications can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and modifications are included in the scope or gist of the invention, and are included in the invention and its equivalents described in the claims. [Explanation of symbols]
