The presentation step (step S21) displayed in 36 is executed. Further, the server-side operation acquisition unit 105 issues an instruction to the terminal-side operation acquisition unit 33, and an operation acquisition step (step S22) of acquiring the operation of the moving body 20 when an event occurs is executed. In the motion acquisition step (step S22), first, a plurality of motion candidates extracted in the preparation step (step S12) are displayed on the display screen 36 side by side with the images before and after the event.

FIG. 7 is a schematic diagram showing an example of display contents displayed on the display screen of the terminal device in the presentation process and the operation acquisition process shown in FIG.

As shown in FIG. 7, in the presentation step (step S21) and the motion acquisition step (step S22), the pre- and post-event images 361 are displayed on the display screen 36 together with the shooting date and time and the shooting location.

Further, along with the images 361 before and after the event, the movement of the moving body 20 at the time of shooting, that is, the message 362 asking the operation that the driver Y was trying to perform at the time of shooting, is extracted in the preparation step (step S12). A plurality of operation candidates 363 that have been performed are displayed.

The driver Y looks back at the situation at the time of the event occurrence by looking at the images 361 before and after the event, and selects the operation of the moving body 20 at the time of the event occurrence from the plurality of operation candidates 363. An answer button 364 is arranged in the lower right corner of the display screen 36, and the driver Y selects one operation from the operation candidates 363 and clicks the answer button 364. One operation acquired by the terminal-side operation acquisition unit 33 in response to such a screen operation by the driver Y is delivered to the server-side operation acquisition unit 105 by the delivery unit 35.

In the process represented by the flowchart of FIG. 6, following the above operation acquisition process (step S22), the server-side result acquisition unit 106 issues an instruction to the terminal-side result acquisition unit 34, resulting in the above-mentioned one operation. The result acquisition step (step S23) of acquiring the result event is executed.

In the result acquisition step (step S23), a plurality of event candidates are presented, and the driver Y is made to select the result event at the time of event occurrence from among them. When one operation is acquired in the operation acquisition process (step S22), the server-side result acquisition unit 106 selects a plurality of events that can occur as a result of the above one operation from the event group that can occur in the mobile body 20. Extract as an event candidate. The server-side result acquisition unit 106 issues an instruction to the terminal-side result acquisition unit 34 to present the extracted plurality of event candidates to the driver Y.

FIG. 8 is a schematic diagram showing an example of a plurality of event candidates displayed on the display screen of the terminal device in the result acquisition process shown in FIG.

In the example of FIG. 8, "straight ahead" is selected as the operation of the moving body 20 when an event occurs, and a plurality of event candidates 365 extracted in response to the movement are arranged in a plurality of stages below the display screen 36. Is displayed so that it can be scrolled. The driver Y selects one result event as a result of the operation "straight ahead" of the moving body 20 when the event occurs from the plurality of event candidates 365. The display screen 36 is provided with a free entry field 366 below the plurality of event candidates 365. When the driver Y selects "another problem has occurred" or "no problem has occurred" from the plurality of event candidates 365, the driver Y knows the situation. It can be specifically described in the free entry column 366. However, what is reflected in the subsequent question preparation is only the result event other than the above two items in the event candidate 365, and the contents of these two items and the free entry column 366 are not reflected. When the driver Y selects a result event from the event candidates 365 and clicks the answer button 364, the terminal side result acquisition unit 34 acquires the result event. This result event is delivered to the server-side result acquisition unit 106 by the delivery unit 35.

FIG. 9 is a schematic diagram showing an example of a display screen when a result event is selected in the result acquisition process shown in FIG.

In the example of FIG. 9, "straight ahead" is selected from the motion candidates 363 as the motion of the moving body 20 when the event occurs, and the event that "it is about to collide with an oncoming vehicle" is an event as a result event at that time. It is selected from the candidates 365. Then, a confirmation column 367 for final answer confirmation is displayed in the center of the screen, and when "Yes" is selected in this confirmation column 367 and the answer button 364 is clicked, the processing on the terminal device 30 is performed. finish. On the other hand, when "return" is selected in the confirmation column 367, the display content on the display screen 36 returns to the content of FIG. 7, and the process is repeated from the operation acquisition process (step S22).

In the process represented by the flowchart of FIG. 6, following the above result acquisition process (step S23), the question creation unit 107 executes the question creation step (step S24). In the question creation step (step S24), a question image and an answer image are set, a question sentence is created, and an answer option for the question sentence is created to create a question. As described above, the question image corresponds to the pre-event image extending from 5 seconds before the event occurrence to immediately before the event occurrence among the pre-event images of the event information. Further, the response image corresponds to the post-event image extending from immediately after the pre-event image to 3 seconds after the event occurs. The question sentence is created by applying the wording representing the action acquired in the action acquisition step (step S22) to the fixed phrase. The answer options are set to include the result event acquired in the result acquisition step (step S23) as a correct answer.

FIG. 10 is a schematic diagram showing an example of a question related to safe driving created in the question creation step shown in FIG.

The question 50 is composed of an image or a sentence displayed on the display screen 36 of the terminal device 30 of the recipient, and before answering, the question image 51, the question sentence 52, the answer option 53, and the answer button 54 Is displayed, and the answer image 55 is displayed after the answer. As for the question image 51, the pre-event image corresponds to this as described above. Question 52 is a phrase that expresses the motion acquired in the motion acquisition process (step S22) in the AAA part of the fixed phrase "I am trying to AAA, but what is the accident that may occur in this operation?" Is created by applying. In the example of FIG. 10, in addition to the acquired motion, the type of road in the event information is also applied to the AAA part. That is, the phrase "go straight on a single road" is applied to the AAA part. Further, as the answer option 53, four options including the result event acquired in the result acquisition step (step S23) as the correct answer 531 are set. The response image 55 corresponds to the post-event image as described above.

The recipient who sees the question image 51 before the answer selects one answer from the four options and clicks the answer button 54. If the answer is correct, a circle is displayed on the display screen 36 and the answer image 55 is displayed. If there is a mistake, a cross mark is displayed on the display screen 36 and the answer image 55 is displayed.
