FIG. 1 is a diagram illustrating an information processing device according to an embodiment. FIG. 1 is a block diagram illustrating an information processing device according to an embodiment. FIG. 13 is a diagram for explaining an example of a question. FIG. 13 is a diagram for explaining an example of a dashboard. 1 is a flowchart illustrating an information processing method according to an embodiment.

One embodiment is described below.

[Overview of information processing device 100]
First, an overview of an information processing device 100 according to an embodiment will be described.
FIG. 1 is a diagram illustrating an information processing device 100 according to an embodiment.

The information processing device 100 may be configured as, for example, a viewing device that allows a user to view content according to the user's desire. The information processing device 100 may also be configured as, for example, a viewing device that allows a user to view a part of a video 300 that is an example of content, starting from the part that interests the user. The information processing device 100 may also be configured as a position identification device that identifies the position (e.g., the start position) of the part of the video 300 that interests the user. The information processing device 100 is not limited to the device of the example described above, and may be configured as various devices.
The information processing device 100 may be a computer such as a server, a desktop, a laptop, a tablet, or a smartphone.

Note that there are various types of content, but below we will use video 300 as an example of content.

The information processing device 100 stores video information on the video 300 to which an index 310 has been added. The index 310 may be, for example, a marker, bookmark, or the like, indicating a playback start position (or a playback start position when playing from the middle) of the video 300 (e.g., a chapter, etc.). One or more indexes 310 may be added to one video 300. Video information may be referred to as video data. A higher-level concept of video information may be, for example, content information, etc.

The information processing device 100 may, for example, ask a question to a user (viewing user) before or after the user watches the video 300 and while the user is watching the video 300. As an example, the information processing device 100 may transmit one or a plurality of questions to a terminal (viewing user terminal 200) used by the viewing user.
Furthermore, the information processing device 100 accepts an answer from the viewing user in response to the question. For example, when a predetermined input is made in the viewing user terminal 200, the information processing device 100 may accept the predetermined input (input information). The predetermined input may be, for example, an input of a multiple-choice answer to a question, or a descriptive answer.
The information processing device 100 may output questions and receive answers (predetermined inputs) in a chat format, for example.

When the information processing device 100 receives an input as described above, it identifies an index 310 (for example, index A) corresponding to the input.
The information processing device 100 may, for example, refer to the correspondence information to identify the index 310 of the video 300 corresponding to the received answer (predetermined input). The correspondence information may, for example, be information that associates one or more questions, answers corresponding to the questions, and the index 310 corresponding to the answers.
Alternatively, the information processing device 100 may, for example, input the received answer into a trained model and identify the index 310 corresponding to the answer. The trained model may be, for example, a model generated by learning one or more questions, answers to the questions, and the index 310 corresponding to the video playback start position when the video 300 is played back according to the answers.

The information processing device 100 plays the video 300 (300A) from a point corresponding to the specified index 310 (e.g., index A, etc.). That is, the information processing device 100 may control the viewing user to view the video 300 (300A (chapter)) from a point corresponding to the specified index 310, for example.
Note that the information processing device 100 may perform control so that the viewing user can view only the video 300A (chapter).
Alternatively, the information processing device 100 may perform control so that the viewing user can view the videos 300 (300B...) (chapters) following the video 300A (chapter) in chronological order along with the video 300A (chapter).

[Details of information processing device 100]
Next, the information processing device 100 according to an embodiment will be described in detail.
FIG. 2 is a block diagram illustrating the information processing device 100 according to an embodiment.

The information processing device 100 includes, for example, a communication unit 121, a storage unit 122, a display unit 123, and a control unit 110. The communication unit 121, the storage unit 122, and the display unit 123 may be an embodiment of an output unit. The control unit 110 includes, for example, a question control unit 111, a reception unit 112, an identification unit 113, and a playback control unit 114. The control unit 110 may be configured, for example, by an arithmetic processing device of the information processing device 100. The control unit 110 (for example, an arithmetic processing device) may realize the functions of each unit (for example, the question control unit 111, the reception unit 112, the identification unit 113, and the playback control unit 114) by, for example, appropriately reading and executing various programs stored in the storage unit 122, etc.

The communication unit 121 is, for example, a communication interface capable of transmitting and receiving various information between the information processing device 100 and a device (external device) external to the information processing device 100.

The storage unit 122 may store, for example, various information and programs. Examples of the storage unit 122 may be a memory, a solid state drive, a hard disk drive, etc. The storage unit 122 may be, for example, a storage area and a server on the cloud, etc.

The storage unit 122 stores video information related to a video to which an index is attached. The index may be, for example, a mark or a bookmark indicating the start position of each chapter. One or more indexes may be attached to one video. The chapter may be, for example, a division indicating different scenes in one video.
As an example, when a company provides a video for business purposes, the video may include a company introduction and a product introduction. Each of the company introduction and the product introduction may be set as a chapter. Thus, for example, an index is assigned to the setting of the start point of the chapter of the company introduction, and similarly, an index is assigned to the setting of the start point of the chapter of the product introduction.
The storage unit 122 may store one or more videos (video information).

The storage unit 122 may store correspondence information that associates one or more questions, answers to the questions, and an index that corresponds to a video playback start position when the video is played back in accordance with the answers.
The question about the corresponding information may be a question posed to the viewing user by the question control unit 111 described later. The question may be, for example, a question about what aspect of the video the viewing user is interested in, that is, what kind of video (chapter) the viewing user wants to view.
The answer of the corresponding information may be any of various expected answers to the above-mentioned question. For example, the answer may be a content that answers the interest of the viewing user, that is, a desired video (chapter) to be viewed.
The index of the corresponding information may be recorded in association with, for example, the contents (eg, summary, title, etc.) of the moving image (chapter) recorded after the index.
The information processing device 100 (e.g., the control unit 110, etc.) can estimate what the viewing user is interested in, i.e., which video (chapter) the viewing user wishes to view, based on the content of the answer to the question. The information processing device 100 (e.g., the control unit 110, etc.) may also store the question and the answer to the question (e.g., the hearing content, etc.) in the storage unit 122. Therefore, the information processing device 100 associates an index indicating the start position of a chapter with the question and the answer so that the video (chapter) estimated to be of interest to the viewing user can be played back.
The correspondence information may include information associating each of a plurality of second selection buttons, which will be described later, with an index of the corresponding chapter.

When multiple videos (video information) are stored in the storage unit 122, the correspondence information may be stored in the storage unit 122 in correspondence with each of the multiple videos (video information). In other words, the correspondence information may be associated with the video (video information).

The display unit 123 is, for example, a display capable of displaying various characters, symbols, images, etc.

The question control unit 111 outputs a question to the viewing user. The question control unit 111 may, for example, read out question information related to the content of the question stored in the memory unit 122, and output the question to the viewing user. The question information may, for example, be recorded in the above-mentioned correspondence information, or may be other information different from the correspondence information. The question content may, for example, be content asking what kind of video the viewing user would like to watch, may be content asking what the viewing user is interested in, or may be various other content. The question control unit 111 may output one or more questions to the viewing user.

The question control unit 111 may ask a question in at least one of the following formats: a selection format in which the viewing user is prompted to select at least one answer from a number of options; a chat format in which questions and answers are exchanged using a chat between the viewing user and the information processing device 100 (e.g., the question control unit 111 such as a chatbot); and a description format in which one question is output and a written answer is obtained.

The question control unit 111 may be capable of outputting a question to the viewing user in response to the input of the viewing user. That is, the question control unit 111 may output a second question to the viewing user in response to the question and the answer when an answer (a predetermined input to be described later) is given to one or more questions asked the first time in chronological order, for example, in the above-mentioned selection format, chat format, description format, and various other formats. In this case, the question information may record the first question, the expected answer to that question, and the second question in response to the question and the answer in association with each other. Note that the number of questions asked in chronological order is not limited to two as described above, but may be three or more.

The question control unit 111 may be capable of outputting a question before or after playing a video (while playback is stopped) and while the video is being played. In other words, the question control unit 111 may output a question to a viewing user before or after the viewing user watches a video and while the viewing user is watching a video (when the video is being played under the control of the playback control unit 114, which will be described later).

Here, for example, when the viewing user uses the viewing user terminal 200 , the question control unit 111 may perform control so as to transmit a question to the viewing user terminal 200 via the communication unit 121 .
Alternatively, the question control unit 111 may perform control so that the question is displayed on the display unit 123 when the viewing user can view the display unit 123 .

Figure 3 is a diagram to explain an example of a question.

As shown in an example in Fig. 3, the question control unit 111 may display a question on the screen of the video being viewed by the viewing user as to which chapter of the video the viewing user wishes to view. In this case, the question control unit 111 may display a "chapter" selection button (first selection button) on the screen of the video, and when the first selection button is operated, may expand a plurality of buttons (second selection buttons) that can select each chapter (for example, selection buttons for "1. Our company", "2. Business", and "3. Fees") as shown in the example of Fig. 3.
When one of the plurality of second selection buttons is selected, the identification unit, which will be described later, may refer to the correspondence information and identify an index corresponding to the selected second selection button.

The receiving unit 112 receives a predetermined input in response to the question output by the question control unit 111. The predetermined input may be, for example, an answer to the above-mentioned question by the viewing user.
The receiving unit 112 may receive the answer of the viewing user transmitted from the viewing user terminal 200 via the communication unit 121, for example.
Alternatively, for example, if the information processing device 100 is provided with an input unit (e.g., a keyboard and a mouse) (not shown), the reception unit 112 may receive the answer of the viewing user input via the input unit.

The identification unit 113 identifies an index according to the input received by the reception unit 112. That is, when the reception unit 112 receives one or more inputs (answers from the viewing user) corresponding to one or more questions output by the question control unit 111, the identification unit 113 may refer to the correspondence information stored in the storage unit 122 and identify one index corresponding to the question and the input. In this case, the identification unit 113 may, for example, estimate a pattern of answers received by the reception unit 112 and identify an index corresponding to the answer pattern. As an example, when multiple questions are asked by the question control unit 111, even if the answers to each of the multiple questions do not completely match the questions and answers recorded in the correspondence information, the identification unit 113 may refer to the correspondence information and estimate the viewing content desired by the viewing user based on a relatively larger number of answers (answer patterns) (for example, a majority vote format, etc.) among the multiple answers, and identify an index corresponding to the viewing content.

Alternatively, the identification unit 113 may identify an index corresponding to a question and an answer by using a trained model. The trained model may be, for example, a model generated by learning one or more questions, answers to the questions, and an index corresponding to a video playback start position when a video is played in response to the answers.
A learning unit (not shown) arranged in the control unit 110 may, for example, perform the above-mentioned learning to generate a trained model. Alternatively, a learning device (not shown) external to the information processing device 100 may, for example, perform the above-mentioned learning in the same manner as the learning unit to generate a trained model. The identification unit 113 may, for example, acquire a trained model generated by the learning unit or the learning device.

That is, the identification unit 113 may identify one index corresponding to the question and the input based on the above-mentioned trained model and one or more inputs (answers from the viewing user) received by the reception unit 112 in response to one or more questions output by the question control unit 111. In other words, the identification unit 113 may, for example, input a question for the viewing user and the viewing user's answer to the trained model, and when an index corresponding to the question and answer is output using the trained model, identify the index.

As an example, the video (chapter) in which the viewing user is interested may change depending on the content of the video being played (the content of the chapter being watched by the viewing user). For this reason, the identification unit 113 may use a model that has further learned the scene (chapter) of the video being played as the learned model. That is, the learned model in this case may be, for example, a model generated by learning the scene (chapter) of the video being played when the question control unit 111 outputs a question, one or more questions, answers to the questions, and an index corresponding to the video playback start position when the video is played in response to the answers.

Even in this case, the identification unit 113 may identify one index corresponding to the content of the video (chapter), the question, and the input based on the learned model, the content of the video (chapter) being played when the question control unit 111 outputs the question, and one or more inputs (answers from the viewing user) received by the reception unit 112 in response to one or more questions output by the question control unit 111.

The playback control unit 114 transmits the video information to the viewing user terminal 200 via, for example, the communication unit 121. In this case, the viewing user terminal 200 plays a video based on the video information and displays it on the terminal display unit 201 (see FIG. 1 ).
Alternatively, the playback control unit 114 may, for example, play a video based on the video information and display it on the display unit 123 .
Here, the playback control unit 114 may play back the video from a position corresponding to the index identified by the identification unit 113. That is, the playback control unit 114 may, for example, identify an index recorded in the video information based on the video information stored in the storage unit 122 and the index identified by the identification unit 113, and perform control so as to play back the video (chapter) from the identified index.

For example, when an index is identified by the identification unit 113 while a video is being played back, the playback control unit 114 may change the playback content and control the video (chapter) to be played back from the index. That is, the playback control unit 114 may play back the video (chapter) from the index identified by the identification unit 113, even if the video being played back and the video to which the index identified by the identification unit 113 is assigned are the same or different.

In addition, for example, when an index is identified by the identification unit 113 while a video is not being played, the playback control unit 114 may identify a video (video information) to which the index identified by the identification unit 113 is assigned, and play a video (chapter) from the identified index within that video.

Alternatively, the playback control unit 114 may issue a URL (Uniform Resource Locator) that enables playback of the video from a position corresponding to the index identified by the identification unit 113. That is, the playback control unit 114 may issue a URL that indicates the position of the storage unit 122 on the communication network and the playback start position of the video so that the video (chapter) stored in the storage unit 122 can be played from a position corresponding to the index identified by the identification unit 113. The playback control unit 114 may transmit the URL to the viewing user (viewing user terminal 200) via the communication unit 121, for example.
The viewing user terminal 200 may, for example, obtain a URL from the information processing device 100, and when the URL is clicked based on the operation of the viewing user, play a video (a video stored in the memory unit 122) from a location corresponding to the index identified by the identification unit 113 and display it on the terminal display unit 201.

In addition, the playback control unit 114 may accept an action from the viewing user (viewing user terminal 200) when playing a video, identify the viewing user's interests in the video based on the action, and control the output unit to perform output according to the identified interests of the viewing user.
As an example, the playback control unit 114 (or each function of the control unit 110, etc.) may have a function (analysis function) that quantitatively analyzes the actions of the viewing users, such as how a company (a company providing a video to a viewing user) is viewed by the viewing user of a video about the company and how much interest the viewing user has in the video, in order to increase the number of effective business negotiations. In the playback control unit 114 (or each function of the control unit 110, etc.), if a company uses the analysis function to allow a viewing user to select a chapter in a video about the company's product or to obtain an answer (answer to a question) from the viewing user, the playback control unit 114 (or each function of the control unit 110, etc.) can provide the company with information on which of a plurality of perspectives of the product (centered on which perspective) is suitable for making a proposal (approach such as a business negotiation) to the viewing user based on the selection and answer (action of the viewing user) (output according to the interest of the viewing user). In other words, the company can create a strategy for business negotiations based on the content of the provision.
As another example, the playback control unit 114 (or each function of the control unit 110, etc.) may obtain the viewing status of the viewing user (action of the viewing user), such as a video being viewed multiple times by one viewing user, an inquiry being made to the company by the viewing user, or the viewing user having viewed the entire video, based on the viewing (viewing information) of the viewing user who is viewing a video provided by the company, and may classify the situation of the company according to each interest phase of the viewing user, and suggest viewing users that the company should approach for business negotiations, etc. (output according to the interests of the viewing user) (Kanban function).
As another example, the playback control unit 114 (or each function of the control unit 110, etc.) may identify potential customers who are interested in the company from among the viewing users who are the recipients of emails in email marketing, based on the viewing (viewing information) of the viewing users who watch videos provided by the company, and may suggest to the potential customers that they should also approach the potential customers by making additional phone calls, etc. (output according to the interests of the viewing users) (Kanban function).

In addition, the playback control unit 114 (or each function of the control unit 110, etc.) can link the content of the hearing with the customer information of the viewing user and confirm it. As an example, when a viewing user is selected by a company staff member from the above-mentioned Kanban function, the playback control unit 114 (or each function of the control unit 110, etc.) may provide the viewing content of the viewing user to the company. In other words, the playback control unit 114 (or each function of the control unit 110, etc.) may provide the company with the viewing content of each viewing user, such as how the viewing user answers questions, what timeline the viewing user is watching the video on, what kind of inquiries the viewing user has made to the company, etc. In other words, company employees can immediately confirm what content to talk about in business negotiations with the viewing user.

The playback control unit 114 (or each function of the control unit 110, etc.) can also conduct business negotiations after collecting advance information (for example, detailed viewing data for each company, a list of companies by interest level, response rates and response contents to interviews, and push target rates, etc.).

Figure 4 is a diagram illustrating an example of a dashboard.

In addition, the playback control unit 114 (or each function of the control unit 110, etc.) can allow other employees to learn by having them view the sales of the top salesman of the company providing the video as if they were in person, and the reactions (actions) of the viewing users may be quantitatively viewable by other employees on a dashboard (see FIG. 4). The playback control unit 114 (or each function of the control unit 110, etc.) can relatively significantly reduce the time allocated to employee training. In this case, the playback control unit 114 (or each function of the control unit 110, etc.) collects various reactions of the viewing users, including questions to the viewing users (questions by the question control unit 111), answers to the questions by the viewing users (predetermined inputs (e.g., answers, etc.) received by the reception unit 112), and evaluations of the viewing users who have viewed the video, and may collectively store the collected results in the storage unit 122 and display them on the display unit 123 (dashboard function). The control unit 110 (each function of the control unit 110, etc.) can display a dashboard (a result summarizing the reactions (actions) of the viewers) such as the example shown in Fig. 4 on the display unit 123. The playback control unit 114 (or each function of the control unit 110, etc.) may control the output unit to tally up the actions of the viewing users and output the tally up result as a dashboard function.
As an example, the playback control unit 114 (or each function of the control unit 110, etc.) can provide the company providing the video with information on which part of the video the viewing users from which source, such as SNS, various advertisements, and searches via a communication network (e.g., organic, etc.), pay attention to, what actions they are taking, where they are likely to leave the video, and in which scene of the video the inquiry button is operated. In other words, the playback control unit 114 (or each function of the control unit 110, etc.) can provide the company with the trend in viewer ratings for each medium and which scenes are attracting attention or being skipped, and can allow the company's employees to prepare a selection of explanations for each source during a business meeting.

[Information processing method]
Next, an information processing method according to an embodiment will be described.
FIG. 5 is a flowchart illustrating an information processing method according to an embodiment.

In step ST101, the question control unit 111 outputs a question to the viewing user. In this case, the question control unit 111 may issue a question while playback of the video is stopped and while the video is being played.

The question control unit 111 may output a question multiple times. In this case, the question control unit 111 may be capable of outputting a question to the viewing user in response to the input of the viewing user.
That is, after outputting the question in step ST101, the information processing device 100 accepts a predetermined input (answer) from the viewing user in step ST102 described later. The process returns to step ST101, and the information processing device 100 may output a further question in response to the previous question and the predetermined input (answer).

In step ST102, the reception unit 112 receives a predetermined input in response to the question output in step ST101. The predetermined input may be, for example, a response from the viewing user in response to the question sent to the viewing user in step ST101.

In step ST103, the specification unit 113 specifies an index according to the input (answer of the viewing user) received in step ST102.
That is, for example, when the identification unit 113 receives one or more inputs (answers from the viewing user) in step ST102 in response to one or more questions output in step ST101, the identification unit 113 may refer to the corresponding information stored in the memory unit 122 and identify one index in response to the question and input.
Alternatively, the identification unit 113 may identify one index corresponding to the question and the input based on the trained model, one or more questions output in step ST101, and one or more inputs (answers from the viewing user) received in step ST102 in response to the questions. The trained model may be, for example, a model generated by learning one or more questions, answers to the questions, and an index corresponding to a video playback start position when the video is played in response to the answers. Note that the identification unit 113 may use, for example, a model that further learns a scene (chapter) of the video being played as the trained model.

In step ST104, the playback control unit 114 may play the video (chapter) from a location corresponding to the index identified in step ST103.

[Functions and circuits]
Next, the functions and circuits of the information processing device 100 will be described.
Each unit of the information processing device 100 may be realized as a function of a computer's arithmetic processing device, etc. That is, the question control unit 111, the reception unit 112, the identification unit 113, and the playback control unit 114 (control unit 110) of the information processing device 100 may be realized as a question control function, a reception function, an identification function, and a playback control function (control function) by the computer's arithmetic processing device, etc.
The information processing program can cause a computer to realize each of the above-mentioned functions. The information processing program may be recorded in a non-transitory computer-readable recording medium, such as a memory, a solid-state drive, a hard disk drive, or an optical disk. The recording medium may be referred to as a non-transitory computer-readable medium, for example.
As described above, each unit of the information processing device 100 may be realized by an arithmetic processing device of a computer or the like. The arithmetic processing device or the like is constituted by, for example, an integrated circuit or the like. Therefore, each unit of the information processing device 100 may be realized as a circuit constituting the arithmetic processing device or the like. That is, the question control unit 111, the receiving unit 112, the identifying unit 113, and the reproduction control unit 114 (control unit 110) of the information processing device 100 may be realized as a question control circuit, a receiving circuit, an identifying circuit, and a reproduction control circuit (control circuit) constituting the arithmetic processing device of a computer or the like.
The communication unit 121, the storage unit 122, and the display unit 123 (output unit) of the information processing device 100 may be realized as a communication function, a storage function, and a display function (output function) including the functions of an arithmetic processing device, etc. The communication unit 121, the storage unit 122, and the display unit 123 (output unit) of the information processing device 100 may be realized as a communication circuit, a storage circuit, and a display circuit (output circuit) by being configured, for example, by an integrated circuit, etc. The communication unit 121, the storage unit 122, and the display unit 123 (output unit) of the information processing device 100 may be realized as a communication device, a storage device, and a display device (output device) by being configured, for example, by being configured by a plurality of devices.

The information processing device 100 can be configured by combining one or any two or more of the above-mentioned units.
In this disclosure, the term "information" is used, but the term "information" can be replaced with "data" and the term "data" can be replaced with "information."

[Example]
Next, an embodiment will be described.

The video may be, for example, a video used for business negotiations.
First, the information processing device 100 displays an initial screen on the display unit (terminal display unit 201) of the viewing user terminal 200. A button for starting negotiation (for example, a start button, etc.) may be displayed on the initial screen.

When the above-mentioned button is pressed, the information processing device 100 starts the business negotiation. In this case, the information processing device 100 may send a question to the viewing user in advance as to what content (chapter) in the business negotiation video the viewing user would like to view. That is, the information processing device 100 may ask the viewing user in advance as to what scene in the business negotiation video the viewing user would like to view.
Based on the answer of the viewing user to the question (hearing), the information processing device 100 allows the viewing user to view the content (chapter) of the video corresponding to the answer.

The information processing device 100 can ask the viewing user questions (interviews) even while the viewing user is viewing a video (chapter). The information processing device 100 can recommend to the viewing user which chapters (scenes) in the video are recommended, based on the viewing user's response to the question (interview) and the viewing user's responses to previous questions (interviews) (answers from the start of the business negotiation to the present).

An example of the exchange of questions and corresponding answers may be performed by acquiring wording in advance from a user of the information processing device 100 (for example, the acquired wording is coded in advance by the development side).
As another example, a user of the information processing device 100 may freely input text and exchange questions and answers.
As another example, the information processing device 100 may determine, based on past data and machine learning (trained model), what kind of answer will be returned when what kind of question (interview) is asked to the viewing user in what situation.
The information processing device 100 may chat with the viewing user in real time while the viewing user is watching a video, or may send a question to the viewing user and receive a response from the viewing user in response.

The information processing device 100 described above accumulates data on what actions the viewing user has taken, what interests they have, etc., and can use the accumulated data to improve the quality of business negotiations.
Furthermore, the information processing device 100 can reproduce the sales activities of the president and top salesperson of the company providing the business negotiation video, thereby providing the viewing user with a sales experience that is close to the real experience.
Furthermore, the information processing device 100 may allow the president or the like to answer on the spot any frequently asked questions that the viewing user may have. The information processing device 100 can provide an experience where the viewing user can directly access what he or she wants to know, and can reduce stress on the viewing user.

The information processing device 100 may also have a function for sharing this system with other users other than the viewing user, that is, a function for sending a message to other users such as "This product seems like it would be a good fit for your company."
Furthermore, when the viewing user presses a number of buttons representing contents that the viewing user wants to know, the information processing device 100 may generate and play one video by combining different videos for each combination of the button presses.
In addition, the information processing device 100 may hold various information in the video and provide different contents of the video (or other videos, etc.) according to the answer obtained from the viewing user. As a specific example, when the viewing user selects (answers) A and B from among the options A, B, C, and D described in the question, the information processing device 100 may generate a video E corresponding to A and B and display (reflect) the video E so that it can be viewed on a screen (user interface) that can be viewed by the viewing user. Similarly, as an example, when the viewing user selects (answers) A, B, and D, the information processing device 100 may generate a video F corresponding to A, B, and D and display (reflect) the video F so that it can be viewed on a screen (user interface) that can be viewed by the viewing user.
Furthermore, the information processing device 100 may be equipped with a rating function for videos (for example, a "like" function, etc.) and may post daily or weekly rankings of videos on the media of this system. In other words, the information processing device 100 can arouse the interest of viewing users by making them think that information-sensitive viewing users are likely to be interested in a currently popular service, and if the number of previews changes as a result, it may be useful as a sales pitch.
Furthermore, the information processing device 100 may automatically distribute the rankings on the above-mentioned media (for example, weekly rankings, etc.) to viewing users by email, etc., every Friday, etc.
The information processing device 100 may also display (reflect) the viewing user (e.g., a company, etc.) currently viewing the video on the management screen of the device in real time. In this case, when the information processing device 100 performs any action in the system (or in the video), such as when the viewing user sees a case study or answers a question (interview), a notification may be sent to a communication means such as email or chat, and the information may be confirmed on the management screen.
The information processing device 100 may also be equipped with a simultaneous translation function. That is, the information processing device 100 may translate the explanation of the present system into the language of each country and allow the viewing user to view it. Also, the subtitles in the video may be reflected in the language of each country. The information processing device 100 may also be able to translate questions (hearings) and answers, inquiry contents, etc. on the management screen.
Furthermore, the information processing device 100 may allow an adopting company to upload videos to the storage unit 122 itself, thereby allowing the company to freely edit chapters and question options, set question items, and so on.
The information processing device 100 may also have a recommendation matching function. That is, when a viewing user (e.g., company A) who uses the present system frequently views "the present system used by telephone appointment company B," the information processing device 100 may automatically recommend sales to potential customers that company C could not find, such as "How about making sales to company A?" to company C that provides an "appointment acquisition service."
The information processing device 100 may also visualize which other videos (this system) provided by company A are frequently viewed by viewing users of the videos (this system) provided by company B, i.e., what needs the viewing users have.
In addition, the information processing device 100 may display behavioral data within the video in a timeline format and analyze where the viewing users are coming from (e.g., SNS, etc.) or what kind of route the viewing users are taking.
Furthermore, the information processing device 100 may link this system with customer relationship management (CRM) or the like via an application programming interface (API) and link the viewing content of the video or the like (viewing data) with data management of a CRM platform, etc. The information processing device 100 may also reflect the viewing data in real time in a linking tool and may reflect the viewing user's interest level and sales priority, etc.
Furthermore, the information processing device 100 may visualize the productivity by creating a management screen that visualizes the productivity-related values that have been made more efficient by this system.
In addition, the information processing device 100 may recommend media of the present system to a viewing user who has viewed the present system multiple times, based on the contents of the viewing. Furthermore, if the viewing user sets points of interest to the viewing user, the information processing device 100 may automatically recommend companies to the viewing user, and may provide only items that the viewing user wants to know about for videos (the present system) of any company.
In addition, the information processing device 100 may acquire history (viewing data) of when a viewing user views multiple videos, and recommend videos (this system) from different companies to each viewing user, such as "Maybe you have a need for this?"
In addition, when the user of the information processing device 100 uploads a video of himself or herself to the memory unit 122, the user can easily use the system by setting a question (e.g., the question content and options for the question, etc.).
The information processing device 100 may also accept a playback start by manual input on a playback time axis designated by the user. In this case, when the accepted playback start position overlaps a number of times above a threshold within a predetermined range on the playback start axis, the information processing device 100 may generate an index at one point within the predetermined range. The information processing device 100 may prompt the user to create a question corresponding to the generated index.
Furthermore, the information processing device 100 may delete indexes that are not used.
