The embodiments of the present invention relate to an information processing device, an information processing method, and an information processing program.

In recent years, remote classes such as online classes using ICT (Information and Communication Technology) have begun to spread in educational settings. In remote classes, unlike conventional group education, it is difficult for teachers to accept questions from students during class, and it is conceivable that teachers will accept questions from students after class ends. In that case, it is necessary for the teacher to efficiently select questions that the students are interested in during the question-and-answer period.

Therefore, it is desired to provide a technology that can associate the content of the lesson with the question, select the question that is most important and of interest to more students, and efficiently conduct question-and-answer sessions.

In a presentation system, there is a technology that ranks questions according to their importance according to the importance of slides based on the voice power of the presenter and the number of questions on the corresponding slides (see Patent Document 1, for example).

Japanese Patent No. 4918524

However, although the technology disclosed in Patent Document 1 can calculate the importance of questions from the number of questions on a slide, the presenter cannot judge the importance of questions from the content of the questions. Also, the presenter cannot grasp which part of the slide the question corresponds to. Therefore, with this technology, it is difficult for the presenter to select questions of high importance based on the content of the presentation and the content of the corresponding questions, and to efficiently conduct question-and-answer sessions.

The present invention has been made with a focus on the above circumstances, and one aspect of the present invention is to provide a technique for realizing efficient selection of highly important questions.

In order to solve the above problems, one aspect of the information processing apparatus of the present invention includes: a first acquisition unit that acquires a plurality of slide images for presentation from a server; and a plurality of slides acquired by the first acquisition unit. A display control unit for displaying a target slide image based on an image, and a second acquisition unit for acquiring first question information including the target slide image and information specifying a question target position based on a user's operation. and an output unit for outputting the first question information acquired by the second acquisition unit to a server.

According to one aspect of the present invention, it is possible to efficiently select questions of high importance.

The display control unit 414 superimposes the second question image based on the second question information acquired by the second acquisition unit 412 on the target slide image based on the question target position related to the second question information. It is displayed on the display unit 45 (step S7). In step S7 , for example, the display control unit 414 creates a second question image based on the second question information acquired by the second acquisition unit 412 . The display control unit 414 creates a second question image including a consent button for inputting consent information for the second question information. The display control unit 414 causes the display unit 45 to display the created second question image superimposed on the question target position of the target slide image based on the slide position information.

The second acquisition unit 412 determines whether or not the consent information for the second question image has been acquired based on the user's operation (step S8). In step S8, for example, the second acquisition unit 412 determines that the consent information for the second question image has been acquired based on the user's input operation via the input unit 44 on the consent button. judge.

When the second acquisition unit 412 determines that the consent information has been acquired (step S8: YES), the process transitions from step S8 to step S9. If the second acquisition unit 412 determines that the consent information has not been acquired (step S8: NO), the process ends.

The output unit 413 outputs the consent information acquired by the second acquisition unit 412 to the server 1 via the network NW (step S9). The consent information includes question identification information that identifies the second question information. The server 1 acquires the consent information output by the output unit 413 and updates the question information DB 132 . For example, the server 1 increments the number of questions included in the question information associated with the question identification information in the question information DB 132 .

Note that the control unit 41 repeats the above steps S2 to S9 each time the target slide image is switched by the presenter's operation.
