<Ideology underlying the first embodiment>
The information processing device according to the first embodiment is a device for managing the timing and type of safety education training to be conducted by each of a plurality of users. Prior to explaining the information processing apparatus according to the first embodiment, the underlying idea will be explained.

The information processing device according to the first embodiment stores a plurality of training scenarios assuming various situations, such as training for dealing with natural disasters, machining, chemical plants, and loading and unloading work in warehouses. , it is possible to provide safety education suitable for each user. The inventor of the present application believes that in order to provide safety education to users, it is preferable to have them experience a plurality of steps in sequence.

FIG. 1 is a diagram for explaining each stage of safety education provided by the information processing apparatus according to the first embodiment. As shown in FIG. 1, the safety education provided by the information processing apparatus according to the first embodiment includes six stages. Specifically, the four stages are ``skills training,'' ``presentation of reenacted images,'' ``providing disaster experience,'' ``safety awareness,'' ``improving disaster response capabilities,'' and ``training simulation.''

"Skills training" is a stage in which the user's body learns the actions needed to move around safely, for example, a stage in which the user performs a driving simulator of a car, working in a warehouse, a simulator of working at heights, etc. "Reproduced video presentation" is a stage in which various patterns of disasters are established as knowledge in users, and various disasters such as general public disasters, industrial accidents, natural disasters, and man-made disasters are reproduced using CG (Computer Graphics). This is the stage where the video footage is repeatedly presented to users as a case study.

"Disaster experience provision" is a stage in which users are allowed to experience disasters that may occur in the workplace using VR (Virtual Reality) technology, depending on the user's environment such as a workplace environment. At this stage, an environment in which a disaster could occur is recreated using VR technology, and the disaster experience is provided in a way that stimulates the user's three or more senses such as sight, hearing, touch, and smell. The aim of providing disaster experiences is to make users aware that disasters are scary things, what they should not do, and what they can do to prevent disasters.

"Safety Awakening" is aimed at users who are highly sensitive to danger by gaining knowledge of disasters through "reproduced video presentation" and experiencing "disaster experience provision," using panoramic VR to show that disasters can occur. Now is the stage to conduct training to point out the parts. In the "safety awareness" stage, for example, situations that can be dangerous for users, such as a collapsing place in a warehouse or a collision at a corner, are recreated using VR technology, and the user is asked to point out the dangerous points to ensure safety. The purpose is to awaken consciousness.

"Disaster response ability improvement" and "training simulation" are not training for general users, but for those who are in a position of instructing others, such as a person equivalent to a superior in an organization, and are training for "safety awareness". This is a training stage for users who have passed through the training stage. Specifically, ``improving disaster response capabilities'' is a stage in which users learn about known disasters through simulation and learn how to deal with them. "Training simulation" is a stage in which actual disaster scenes are simulated in chronological order, and users are asked to virtually carry out disaster response actions.

In this way, the safety education provided by the information processing device according to the first embodiment consists of multiple stages, among which are "presentation of reenacted video", "provision of disaster experience", and "safety awareness". The inventor of the present application recognized that the three steps are highly important. In addition, the inventor of the present application believes that it is difficult to make users take root in these exercises by simply having them experience ``reproduced video presentation,'' ``providing disaster experiences,'' and ``safety awareness,'' and that the timing of each training and training needs to be adjusted for each user. I came to realize the importance of managing the number of times and training appropriately.

Crisis management training can sometimes place a psychological burden on users. It is known that people have the characteristic of forgetting what they have experienced in order to ensure their mental safety. For this reason, in the stage of presenting reenacted images to establish various patterns of disasters as knowledge, the educational effect is improved by repeatedly presenting the reenacted images before the user forgets the knowledge. Sensitivity to crisis is essentially the same as memory, and even in the case of ``providing disaster experiences,'' even if users acquire sensitivity to crisis, it declines over time. Therefore, it is important to continually provide users with disaster experiences over a period of time so that they always have a sense of crisis. The inventor of the present invention has found through experiments that a user's crisis sensitivity decreases after about 10 to 12 months.

Furthermore, "safety awareness" training, which requires users to point out locations where disasters can occur, will only be highly effective if it is administered to users who have knowledge of various patterns of disasters and who are highly sensitive to crises. The inventor of the present application has also found that it can be obtained. Based on the above, the information processing device according to the first embodiment aims to manage the timing and type of safety education training to be conducted by each of a plurality of users, and improve the retention of the training.

<Overview of the first embodiment>
FIG. 2 is a diagram schematically showing an example of an overview of the configuration of the information processing system S according to the first embodiment. Specifically, FIG. 2 is a diagram illustrating an outline of the configuration of the information processing system S assuming that the information processing system S conducts crisis management training for a plurality of employees belonging to an organization.

The information processing system S shown in FIG. 2 includes an information processing device 1, a plurality of user terminals 2 (in the example shown in FIG. 2, a first user terminal 2a and a second user terminal 2b), and a monitor 3. , an information processing device 1 is communicably connected to a user terminal 2 and a monitor 3 via a communication network N such as the Internet.

The information processing device 1 manages at least three training situations for each user as a training history: "Present video reproduction," "Provide disaster experience," and "Awaken to safety." The information processing device 1 refers to the training history and sends a notification to the user that the user should undergo training when the time for training approaches, or provides training to the user. I do things.

Training for presenting reproduced images only requires that the information be presented to the user in some form, and the user does not necessarily have to concentrate on watching the images at the monitor. Therefore, in the example shown in FIG. 2, the information processing device 1 presents a reproduced image on the monitor 3 installed in the employee cafeteria of the organization to which the user belongs. Naturally, if the user wishes to concentrate on watching the video, the information processing device 1 individually delivers the reproduced video to the first user terminal 2a, which is a smartphone owned by the user. Furthermore, in training using VR technology such as disaster experience provision, the information processing device 1 distributes training content to the second user terminal 2b, which is a head-mounted display worn by the user.

The information processing device 1 sequentially conducts three trainings for each user: "presenting a reenactment video," "providing a disaster experience," and "awareness of safety." The conditions for proceeding to ``Safety Awakening'' are predetermined. Specifically, the number of times each user must undergo training for ``presenting reenacted images'' before proceeding to ``providing disaster experiences'' is determined, and the period at which each user must undergo training for presenting reenacted images is also determined. There is. The information processing device 1 performs the reproduced image presentation training again for each user after a period corresponding to the cycle has passed since the last time the user was presented with the reproduced image presentation training. Then, training for providing a disaster experience is conducted for users who have undergone training for presenting reenacted images a predetermined number of times. The conditions for users to proceed to the ``Safety Awareness'' training are the same, but in order to proceed to the ``Safety Awareness'' training, users must at least receive training in ``Presenting reenacted images'' and ``Providing disaster experience''. is preferred.

In this way, the information processing device 1 refers to the training history and notifies and conducts the training to each user according to predetermined conditions, so that the information processing device 1 can perform training related to safety education that should be performed by each of the plurality of users. manage the timing and type of Thereby, the information processing device 1 can efficiently make the results of the training regarding crisis management stick to the users.

<Functional configuration of information processing device 1 according to the first embodiment>
FIG. 3 is a diagram schematically showing the functional configuration of the information processing device 1 according to the first embodiment. The information processing device 1 includes a storage section 10, a communication section 11, and a control section 12. In FIG. 3, arrows indicate main data flows, and there may be data flows that are not shown in FIG. In FIG. 3, each functional block shows the configuration of a functional unit, not the configuration of a hardware (device) unit. Therefore, the functional blocks shown in FIG. 3 may be implemented within a single device, or may be implemented separately within multiple devices. Data may be exchanged between functional blocks via any means such as a data bus, a network, or a portable storage medium.

The storage unit 10 includes a ROM (Read Only Memory) that stores the BIOS (Basic Input Output System) of a computer that implements the information processing device 1, a RAM (Random Access Memory) that serves as a work area of the information processing device 1, and an OS (OS). A large-capacity storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) that stores the operating system), application programs, and various information that is referenced when the application program is executed, and includes a history storage unit 100. I'm here.

The communication unit 11 is a communication interface for the information processing device 1 to communicate with external equipment such as the user terminal 2, and is realized by a known communication module. Hereinafter, when each unit of the information processing device 1 communicates with an external device, the description thereof may be omitted on the premise that the communication unit 11 is used as an intermediary.

The control unit 12 is a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) of the information processing device 1, and by executing a program stored in the storage unit 10, the video presentation unit 120, disaster experience It functions as a providing section 121 , a discovery opportunity providing section 122 , a video presentation management section 123 , an experience provision management section 124 , and an opportunity provision management section 125 .

Note that FIG. 3 shows an example in which the information processing device 1 is configured as a single device. However, the information processing device 1 may be realized by calculation resources such as a plurality of processors and memories, such as a cloud computing system, for example. In this case, each unit constituting the control unit 12 is realized by executing a program by at least one of a plurality of different processors.

The video presentation unit 120 presents the user with reenactment videos of multiple types of disasters. Further, the disaster experience providing unit 121 provides the user with a virtual experience related to at least one disaster among the plurality of types of disasters. The discovery opportunity providing unit 122 provides the user with the opportunity to discover dangerous spots on the condition that the video presenting unit 120 presents the reproduced video to the user and the disaster experience providing unit 121 provides the user with a virtual experience. provides users with a hidden virtual environment. Thereby, the information processing device 1 can provide an opportunity to wake up safety concerns to users who have acquired knowledge about disasters and have increased their sensitivity to danger.

As described above, the information processing device 1 periodically presents reenactment videos of a plurality of types of disasters to the user in order to improve the user's memory. In order to achieve this, the video presentation management unit 123 causes the video presentation unit 120 to present the reproduced video according to the video provision interval determined as the interval at which the reproduced video is presented to the user.

Further, the information processing device 1 periodically provides the user with a disaster experience in order to maintain the user's sensitivity to danger. In order to achieve this, the experience provision management section 124 causes the disaster experience provision section 121 to provide a virtual experience according to a virtual experience interval, which is an interval at which virtual experiences are provided to users. Note that the virtual experience interval is a different interval from the video provision interval. Although details will be described later, the virtual experience interval is set to be longer than the video provision interval. More specifically, while the virtual experience sensation lasts for 10 to 12 months, the video provision sensation lasts from about 1 day to several months.

In this way, the video presentation management unit 123 and the experience provision management unit 124 can enhance the training effect for users by managing the timing of presenting the disaster reenactment video and the timing of providing the disaster experience, respectively. .

(Video presentation interval)
The details of the video presentation interval will be explained. The video presentation management unit 123 according to the first embodiment instructs the disaster experience providing unit 121 to provide a virtual experience to the user according to the video presentation interval determined based on the Ebbinghaus forgetting curve. Although a detailed explanation will be omitted as this is a well-known fact, the Ebbinghaus forgetting curve is the decay of the "saving rate" over time, which indicates how much time a person can save to rememorize something they have already memorized. It shows the rate.

FIG. 4 is a diagram schematically showing the Ebbinghaus forgetting curve. In FIG. 4, the horizontal axis shows the passage of time, and the vertical axis shows the saving rate. Furthermore, in FIG. 4, the broken line indicates the attenuation of the saving rate when the reproduced image is presented only once, and the solid line indicates the attenuation of the saving rate when the reproduced image is repeatedly presented at intervals. As shown by the broken line in FIG. 4, when the reproduced image is presented only once, the saving rate monotonically decays over time. This means that once a user has memorized the content of a reproduced video, the amount of time it takes to rememorize that content decreases over time. It shows that time increases with time.

On the other hand, as shown by the solid line in FIG. 4, the user's saving rate can be maintained at a high level by viewing the reproduced image repeatedly after a certain period of time after viewing the reproduced image for the first time. Generally, it is said that if a user reviews the material three times within one month, the rate of retention in long-term memory will improve. The storage unit 10 of the information processing device 1 according to the first embodiment is set in advance to present the reproduced video at least again one day, one week, and one month after the introduction of the reproduced video is presented. The video presentation interval is stored. The video presentation management unit 123 can promote fixation of the reproduced video to the user by causing the video presentation unit 120 to present the reproduced video according to the video presentation interval determined based on the Ebbinghaus forgetting curve.

(Virtual experience interval)
Explain the details of the virtual experience interval. In order to maintain the user's sensitivity to danger, the experience provision management unit 124 according to the first embodiment repeatedly provides disaster experiences at timings when the user's sensitivity to danger decreases.

FIG. 5 is a diagram schematically showing a graph showing the time course of sensitivity. The graph shown in FIG. 5 was found through experiments by the inventor of the present application, and the horizontal axis represents the passage of time, and the vertical axis represents the user's sensitivity to danger. The example shown in FIG. 5 shows that the user experiences an environment where a disaster can occur for the first time at time T1, and then his sensitivity to danger increases and then gradually decreases.

At T2, about 12 months after T1, the user's sensitivity to danger decreased, so the experience provision management unit 124 controlled the disaster experience provision unit 121 to make the user experience an environment where a disaster could occur again. . As a result, the user's sensitivity to danger increases again, but after that, at T3, about 10 months later, the user's sensitivity to danger decreases, so the experience provision management section 124 controls the disaster experience provision section 121. This allowed users to experience an environment in which a disaster could occur again.

In this way, even if users experience an environment where a disaster can occur, their sensitivity to danger gradually decreases, so in order to maintain the user's sensitivity to danger, the Opportunity Provision Management Department 125 The system allows users to repeatedly experience an environment in which a disaster can occur. Thereby, the experience provision management unit 124 can maintain the user's sensitivity to danger.

(Message notification based on training history)
As mentioned above, in order to fix the memory of the reenacted images and maintain sensitivity to danger, users need to watch reenacted images at appropriate times and experience environments where disasters can occur. be. Here, if there are many users of the information processing device 1, securing a venue and training equipment, coordinating the schedules of users, etc. become complicated, and it is difficult to train multiple users at once. It can happen.

Therefore, for each of a plurality of users, the history storage unit 100 stores the means for notifying the user, the date and time when the reproduced video was presented, and the date and time when the virtual experience was provided in association with each other as a training history. The experience provision management unit 124 refers to the training history stored in the history storage unit 100 and notifies the user terminal 2 of the user whose timing has come to provide the virtual experience with a message urging the user to view the virtual experience. do.

FIG. 6 is a diagram schematically showing an example of the data structure of the training history stored in the history storage unit 100 according to the first embodiment. The training history shown in Figure 6 shows the history of the date and time when the replay video was presented, the total number of times the replay video has been presented so far, and the date and time when the virtual experience was provided, in association with the user identifier assigned to each user. It stores a history and the total number of virtual experiences provided so far, a history of dates and times when discovery opportunities were provided, a total number of discovery opportunities provided so far, and a means for notifying the user.

By referring to the training history, the video presentation management unit 123 can obtain the history of dates and times when reproduced videos were presented for each user. Based on this history and the Ebbinghaus forgetting curve illustrated in FIG. 4, the timing for presenting the next reproduced video for each user is determined and notified to the user. Thereby, the video presentation management unit 123 can manage the schedule for presentation of reproduced video for each user.

Similarly, the experience provision management unit 124 can also obtain the history of dates and times when virtual experiences were provided for each user by referring to the training history. Based on this history and the curve showing changes in sensitivity illustrated in FIG. 5, the timing to provide the virtual experience for each user is determined and notified to the user. Thereby, the experience provision management unit 124 can manage the schedule for providing virtual experiences for each reviewer.

The inventor of the present application has found through experiments that the user's safety awareness can be effectively awakened only when the user has acquired knowledge about disasters and has heightened sensitivity to danger. Therefore, by referring to the training history, the opportunity provision management unit 125 provides a discovery opportunity when the specified conditions regarding the number of times the reproduced video is presented to the user and the number of times the virtual experience is provided to the user are met. The unit 122 is made to provide a virtual environment in which danger points are hidden for the user to discover.

Here, the ``conditions set for the number of times a reproduced video is presented to the user and the number of times the virtual experience is provided to the user'' are determined to balance the effectiveness of the training given to the users and the period required for the training. It can be determined by experiment. As an example, the number of times the reenactment video was presented is 5 or more times, the number of times the virtual experience was provided is 3 or more times, it has been less than one week since the last time the reenactment video was presented, and the last time the virtual experience was provided. The predetermined condition is that the service is provided within one month. Thereby, the opportunity provision management unit 125 can provide an opportunity to wake up to safety to users who have acquired knowledge about disasters and have increased their sensitivity to danger.

<Processing flow of the information processing method executed by the information processing device 1>
FIG. 7 is a flowchart for explaining the flow of information processing executed by the information processing device 1 according to the first embodiment. The processing in this flowchart starts, for example, when the information processing device 1 is started up.

The video presentation unit 120 presents reproduction videos of multiple types of disasters to the user (S2). Specifically, the video presentation management unit 123 determines the timing to present the next reproduced video for each user based on the date and time of presenting the reproduced video obtained by referring to the training history and the Ebbinghaus forgetting curve. Then, the disaster experience providing section 121 is caused to present a reenactment video.

The discovery opportunity providing unit 122 provides the user with a virtual experience regarding at least one disaster among the plurality of types of disasters (S4). Specifically, the experience provision management unit 124 provides the next virtual experience for each user based on the virtual experience provision date and time obtained by referring to the training history and the graft indicating changes in sensitivity to danger. The timing is determined and the discovery opportunity providing unit 122 is caused to provide the virtual experience.

Until the conditions set for the number of times the reproduced video is presented to the user and the number of times the virtual experience is provided to the user are satisfied (No in S6), the information processing device 1 performs the steps S2 and S4 described above. Repeat the process. If the predetermined conditions regarding the number of times the reproduced video has been presented to the user and the number of times the virtual experience has been provided to the user are satisfied (Yes in S6), the discovery opportunity providing unit 122 creates a dangerous spot for the user to discover. provides a hidden virtual environment (S8). Specifically, the opportunity provision management unit 125 checks whether the conditions are met by referring to the training history, and if the conditions are met, controls the discovery opportunity provision unit 122 to provide the virtual environment to the user. let

When the discovery opportunity providing unit 122 provides the virtual environment to the user, the processing in this flowchart ends. By executing the above processing for all users, the information processing device 1 can manage the training schedule for each user and efficiently establish the results of training related to crisis management. can.

<Effects achieved by the information processing device 1 according to the embodiment>
As described above, the information processing device 1 according to the embodiment can provide a technique for managing training performed by a user.

<Second embodiment>
An overview of the second embodiment will be described. The information processing device according to the second embodiment proposes a training menu that the information processing device 1 according to the first embodiment provides to the user, and the user Provides information to assist in installing the information processing device 1. As explained in the first embodiment, "reproduced video presentation" is a stage to make users familiar with various patterns of disasters, including general public disasters, industrial accidents, natural disasters, man-made disasters, etc. This is the stage where CG reproductions of various disasters are repeatedly presented to users as case studies. Since the purpose is to increase the user's knowledge, the images presented to the user do not have to depend on the industry of the organization to which the user belongs.

On the other hand, "disaster experience provision" is a stage in which users are allowed to experience, for example, disasters that may occur in the workplace using VR technology, in accordance with the user's environment such as a workplace environment. Therefore, it is preferable that the virtual experience provided to the user is tailored to the type of industry of the organization to which the user belongs. For example, it is thought that even if users engaged in the construction of high-rise buildings are allowed to virtually experience cases that may occur in a chemical plant, it will not be of much use in their daily work.

Therefore, the information processing device according to the second embodiment analyzes the industry type of the customer to whom the information processing device 1 according to the first embodiment was provided in the past and the virtual experience introduced at that time, and newly provides the information processing device 1 according to the first embodiment. A virtual experience suitable for a customer who wishes to install the information processing device 1 according to the first embodiment is proposed. Thereby, the information processing apparatus according to the second embodiment can assist a customer who has introduced the information processing apparatus 1 according to the first embodiment.

The information processing device according to the second embodiment may be the same device as the information processing device 1 according to the first embodiment, or may be realized as a different device. The following description will be made on the premise that the information processing apparatus 1 according to the first embodiment and the information processing apparatus 1 according to the second embodiment are the same apparatus (information processing apparatus 1). For convenience of explanation, only the configuration for proposing a virtual experience suitable for the customer will be described below, and functional configurations common to the information processing device 1 according to the first embodiment will be omitted or simplified as appropriate.

<Functional configuration of information processing device 1 according to second embodiment>
FIG. 8 is a diagram schematically showing the functional configuration of the information processing device 1 according to the second embodiment. The information processing device 1 includes a storage section 10, a communication section 11, and a control section 12.

The storage unit 10 stores a ROM that stores the BIOS, etc. of a computer that implements the information processing device 1, a RAM that serves as a work area of the information processing device 1, an OS, an application program, and various information that is referenced when the application program is executed. It is a large-capacity storage device such as an HDD or SSD for storing data, and includes a usage record database 101. The communication unit 11 is a communication interface for the information processing device 1 to communicate with external equipment such as the user terminal 2 used by a new user, and is realized by a known communication module.

The control unit 12 is a processor such as a CPU or GPU of the information processing device 1, and executes a program stored in the storage unit 10 to control the request reception unit 126, extraction unit 127, candidate presentation unit 128, and decision reception unit. 129.

The usage record database 101 stores attribute information indicating the attributes of a user who has used the information processing device 1 according to the first embodiment and a virtual experience that the user has selected to use, in association with each other. . Here, the "user attributes" are parameters indicating the characteristics of the information processing device 1 according to the first embodiment, and include, for example, the industry type of the organization to which the user belongs (e.g., retail industry, customer service industry, manufacturing industry). , construction industry, etc.) and type of industry (e.g., agriculture, forestry and fisheries, mining, manufacturing, public utilities, transportation/communications/warehousing, construction, commerce, finance/insurance/real estate, other service industries, etc.) Contains information.

The request receiving unit 126 receives an introduction request including the user's attribute information from a new user. The extraction unit 127 extracts one or more scenario candidates to be provided to a new user by referring to the usage record database 101 based on the attribute information included in the introduction request received by the request reception unit 126.

FIG. 9 is a diagram schematically showing the data structure of the usage record database 101 according to the second embodiment. As shown in FIG. 9, the usage record database 101 is linked to the user identifier indicating the client who made the introduction request, including the introduction date, the client's industry type, the client's attribute information, and the use of the introduced virtual experience. The number of times (monthly average number of startups) is memorized. The client's attribute information includes the client's business type and industry type, and the scale of the client's organization.

In the example of the usage record database 101 shown in FIG. 9, the user whose user identifier is UID00001 is in the industry (manufacturing industry) whose industry identifier is IID020, and whose industry identifier is IID021 (shipbuilding industry). . This user has introduced four types of virtual experiences indicated by SID003-006 and SID012, and the monthly average number of activations of these experiences is W, X, Y, and Z times, respectively. In the utilization record database 101 shown in FIG. 9, the scale "B" indicates that the number of employees is 100 or more and less than 1000.

FIG. 10 is a diagram schematically showing the functional configuration of the extraction unit 127 according to the second embodiment. As shown in Figure 10, the extraction unit 127 includes a similarity calculation unit 1270 and an experience extraction unit 1271.

The similarity calculation unit 1270 calculates the similarity between attribute information indicating user attributes stored in the usage record database 101 and attribute information included in the introduction request. For example, if the new user's industry is manufacturing, the industry is shipbuilding, and the preference is B, the similarity calculation unit 1270 calculates the similarity with the user whose user identifier is UID00001 in the usage record database 101. is calculated as a high value.

As an example, the similarity calculation unit 1270 calculates the similarity between the attribute information indicating the user's attributes stored in the usage record database 101 and the attribute information included in the introduction request using a real value from 0 to 100. However, the larger the value of the number, the higher the number. The similarity calculation unit 1270 may use any method to calculate the similarity. For example, a table may be created in which scores indicating similarity are determined in advance for each industry type, industry type, and scale. , the degree of similarity may be calculated by totaling each score from the attribute information indicating the user's attributes stored in the usage record database 101 and the attribute information included in the introduction request.

The experience extraction unit 1271 preferentially extracts virtual experiences associated with attribute information with a high degree of similarity in the usage history database 101 as candidates. In particular, the experience extraction unit 1271 may preferentially extract a virtual experience that has been activated relatively many times as a candidate among virtual experiences associated with attribute information having a high degree of similarity.

The candidate presentation unit 128 presents the virtual experience candidates extracted by the extraction unit 127 to a new user. By looking at the presented candidates, the user ultimately decides which virtual experience to introduce. The decision reception unit 129 receives a decision experience, which is a virtual experience for deciding to introduce the system, from a new user.

In this way, the information processing device 1 according to the second embodiment analyzes the usage history of users who have already conducted training related to crisis management using the information processing device 1 according to the first embodiment. By doing so, it is possible to recommend a virtual experience that is appropriate to introduce to users who are newly taking training related to crisis management. Thereby, the information processing device 1 according to the second embodiment can further enhance the effectiveness of the training performed by the user.

Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes can be made within the scope of the gist. be. For example, all or part of the device can be functionally or physically distributed and integrated into arbitrary units. In addition, new embodiments created by arbitrary combinations of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiment resulting from the combination have the effects of the original embodiment.
