Human emotions can be broadly divided into positive emotions and negative emotions. Here, when the user is in a negative psychological state (hereinafter referred to as a negative state), for example, even if there is a question or questionnaire from the system, the answer to the question or questionnaire is rarely given.

This technology was made in view of such a situation, and makes it possible to more reliably obtain the user's answer to a question including multiple options.

The information processing device of one aspect of the present technology includes a presentation control unit that controls the presentation of the option task to the user in response to the estimation of the positive state of the user by the estimation unit that estimates the positive state of the user. Be prepared.

In one aspect of the present technology, the presentation of the option task to the user is controlled according to the estimation of the positive state of the user by the estimation unit that estimates the positive state of the user.

<1. Basic configuration>
(Configuration example of information presentation system)
FIG. 1 is a block diagram showing a configuration of an embodiment of an information presentation system to which the present technology is applied.

The information presentation system 1 of FIG. 1 acquires data indicating a user's behavioral status, estimates whether the user is in a positive state, and if the user estimates that the user is in a positive state, prompts a selection and makes a decision to the user. It controls the presentation of alternative tasks so that they are allowed to do so.

The choice task is a task in which a question including a plurality of choices is given and the choice is selected by the user's decision. In the choice task, a finite number (for example, about 2 to 5) of multiple choices are presented. Hereinafter, the user selecting an option in response to the presentation of the option task is referred to as performing the option task.

Further, when the purpose of presenting the option task is to acquire the subjective data of the user by, for example, a questionnaire, the selection result of the option by the user is used as user information about the user such as the attribute information of the user and the preference information of the user. NS. The user information will be described in more detail later.

On the other hand, when the purpose of presenting the option task is a part of the service for the user in the information presentation system 1, the selection result of the option by the user is, for example, to transition the state of the service in the information presentation system 1 to the next state. It is used as a trigger for.

Specifically, when the service (application) for the user is, for example, a schedule or a to-do list, an option task including options related to items (such as an appointment or event) included in the schedule or to-do list is presented. Ask the user to confirm each item. Depending on the selection result, the information presentation system 1 can shift the state of each item to a state such as preferentially presenting or processing in the background. Specifically, if you change the schedule A, which is one of the items, to participate, the schedule A will be presented preferentially, and if you change the schedule B, which is one of the items, to cancel, the cancellation to the schedule B will be performed. Processed in the background.

When the service for the user is, for example, playback of content such as a song or a program, an option task including a plurality of contents as options is presented, and the user is made to select the content. Based on the selection result, the information presentation system 1 can, for example, determine the content to be reproduced next and move it to the reproduction state.

Then, by presenting the option task configured as described above based on the following conditions, the option task can be quickly performed by the user in the positive state. That is, according to the present technology, it is possible to make the user answer a question including choices more reliably. In other words, according to the present technology, it is possible to more reliably obtain the user's answer to the question including the choices. The conditions of the option task will be described below.

・ Use questions that are not of high importance.
The reason is that, for example, when a person is in a positive state, he or she tends to "do not ponder." Therefore, questions with high importance of answer content, such as irreversible selection or one-time selection, are not suitable for the choice task. On the other hand, it is suitable for a choice task, for example, a question that the user wants to answer but the answer is delayed.
• Make sure that the presentation or content of the alternative task does not offend the user.
The reason is that, for example, when an option task including an offensive question is presented, or when an option is presented at an offensive timing, the positive state of the user is reduced. This is to connect to.

In FIG. 1, as an example of the option task, when the user is estimated to be in a positive state, the option task including the two options "Are you tired when you wake up? Yes / No" is voiced. The example presented by is shown.

The option task in FIG. 1 is an example of an option task whose presentation purpose is acquisition of user's subjective data and whose selection result is used as user information.

By presenting such an option task when the user is in a positive state, it is possible to more reliably obtain the user's answer to the question including the option.

Here, the positive state means, for example, a state in which the sympathetic nervous system is suppressed and the activity of the parasympathetic nervous system is activated. In this case, the positive state may be estimated using, for example, fluctuations in heart rate, sympathetic nerve activity represented by LF (Low Frequency) / HF (High Frequency) in heart rate variability, or mental sweating as an index. ..

The positive state is, for example, a state in which the right frontal lobe is suppressed with respect to the left frontal lobe. In this case, the positive state is estimated by measuring the α-band power of the EEG.

The positive state may be estimated based on, for example, prosodic features in the user's utterance. At this time, if the predetermined frequency band in the prosody exceeds the reference value, it can be estimated to be in a positive state.

The positive state may be estimated based on the recognition of the user's facial expression, for example. When the captured facial expression of the user is classified into a facial expression in which the feature amount of the facial expression is positive, it can be estimated that the user is in a positive state.

The positive state may be estimated based on various models that define the emotional state. The positive state may be defined as a pleasant state in the so-called Russell's emotional ring model, which defines a human emotional state based on, for example, two axes of arousal / inactivity and comfort / discomfort.

Further, the positive state may be defined based on the result statistically estimated by the information presentation system 1 according to the user's attribute and behavioral situation.

For example, when the user hears a laughter while the user is spending time in the living space, or when the user's facial expression smiles, it can be estimated that the user is in a positive state. It is assumed that laughter and smiles are caused by, for example, conversational exchanges and viewing of television and Web contents.

For example, when a user is browsing Web content or writing a sentence, it can be estimated that the user is in a positive state when the content of the content is generally correlated with positive information.

Specifically, if the content is a video, the video of a celebrity you like is displayed, or the video of a person or animal smiling or performing a happy movement is displayed. , These images are one of the factors that put the user in a positive state. In addition, when the text created by the user contains characters such as love, happiness, deliciousness, or fun, these texts are one of the factors that can be presumed to be a positive state by the user. The text is not limited to the input information, and may be voice recognition of the user's utterance.

Also, when a user is watching a sports match on TV, the situation that the supporting team is winning is one of the factors that presumes that the user is in a positive state. For example, in the course of the game, the situation when the supporting team reverses or the favored player plays an active part is one of the factors for presuming that the user is in a positive state.

The information presentation system 1 can estimate the user state based on one or more of the factors presumed to put the user in the positive state.

In FIG. 1, the information presentation system 1 is composed of an input device 11, an information processing device 12, and an output device 13.

Further, in the information presentation system 1, the input device 11, the information processing device 12, and the output device 13 are connected to each other via a network 21 such as a wireless LAN (Local Area Network).

Specifically, the sensor unit 31 recognizes the shape of the living space, existing home appliances / furniture, and grasps their arrangement. In addition, the sensor unit 31 acquires information outside the living space such as weather and temperature. In this case, the sensor unit 31 is composed of, for example, an image sensor, LiDAR, a temperature sensor, an illuminance sensor, a Web camera connected via the Internet, an input unit for acquiring information from a website or the like.

The sensor unit 32 recognizes various information and actions of the user, and outputs the biometric information of the user obtained as a result of the recognition and the action status information indicating the action status of the user to the information processing device 12.

Specifically, the sensor unit 32 recognizes information such as the presence / absence of users in the living space, the number of people, the posture, and the face orientation. Further, the sensor unit 32 recognizes what the user is doing now and the behavioral status of the user. In this case, the sensor unit 32 includes a motion capture system such as OptiTrack (trademark), a distance image sensing system that measures the distance to an object using an image sensor, an infrared camera, a high-resolution depth sensor, and the like.

The sensor unit 32 further acquires the user's biological information (heartbeat, etc.). In this case, the sensor unit 32 may be a heart rate sensor, a sweating sensor, a brain wave sensor, a temperature sensor, or the like, and may be a wristband, an HMD (Head Mount Display), a glass type display, or the like including these. Alternatively, the sensor unit 32 may be a camera capable of measuring a heart rate value, a microphone capable of inputting prosody in utterance or utterance, or the like.

The sensor unit 33 acquires operation information by user's operation input or voice input, and outputs the acquired operation information to the information processing device 12.

Specifically, the sensor unit 33 acquires the input operation information such as the voice and operation when the user performs the presented option task, or the operation when inputting information such as the user's to-do list. In this case, the sensor unit 33 is composed of a keyboard, a touch panel, operation buttons, a controller, a smart phone, a tablet terminal, a microphone, or the like.

The information processing device 12 is composed of, for example, a personal computer or the like. The information processing device 12 estimates the user's emotions, for example, whether or not the user is in a positive state, based on the information supplied from the input device 11. When the user estimates that the user is in a positive state, the information processing device 12 generates an option task based on the information supplied from the input device 11 and causes the output device 13 to present the generated option task.

The output device 13 is composed of a visual presentation device 41, a voice presentation device 42, and the like. The output device 13 presents an optional task supplied by the information processing device 12.

(Configuration example of information processing device)
FIG. 2 is a block diagram showing a functional configuration example of the information processing apparatus.

In FIG. 2, the information processing apparatus 12 is configured to include an emotion estimation unit 61, a task generation unit 62, an output control unit 63, a database 64, a database update unit 65, and a content determination unit 66. In addition, these functions are configured by expanding a predetermined program or the like into RAM (Random Access Memory) or the like by the CPU (Central Processing Unit) of the information processing apparatus 12.

The emotion estimation unit 61 is based on at least one of the external environment information, the user's biometric information, and the user's behavioral status information supplied from the input device 11, and the user's emotion, for example, the user is in a positive state. Estimate whether or not. When the user estimates that the user is in a positive state, the emotion estimation unit 61 causes the task generation unit 62 to generate a choice task.

Further, when the emotion estimation unit 61 estimates that the user is not in the positive state, the content determination unit 66 causes the content determination unit 66 to determine the positive content to be presented to the user.

Positive content is content that makes the user's emotions positive, and is not particularly limited. For example, the positive content may be a video in which a celebrity of the user's taste appears or a song of the user's taste. In addition, the positive content may be an instruction of an action that makes the user's emotions positive.

The task generation unit 62 determines the content and presentation destination of the option task based on the external environment information supplied from the input device 11, the biometric information of the user, the behavior status information of the user, the information registered in the database 64, and the like. Determine the device for and generate a choice task. The task generation unit 62 outputs the generated option task to the output control unit 63.

The output control unit 63 causes the output device 13 to present the optional tasks supplied from the task generation unit 62. The output control unit 63 causes the output device 13 to output the positive content supplied from the content determination unit 66. The output control unit 63 also controls the on / off of the power supply of the output device 13. Further, the output control unit 63 transmits a response from the user, for example, as questionnaire information to a corresponding server (not shown) via a network (not shown).

In the database 64, personal information including user attribute information, user preference information, personality characteristics, etc. are registered as user information regarding the user. Further, as user information, user behavior tendency information including user to-do list and schedule, user habit information, and information on response tendency and behavior tendency to user's choice task is also registered in the database 64. ..

The database update unit 65 updates the information registered in the database 64 based on the external environment information supplied from the input device 11, the biometric information of the user, the behavior status information of the user, the operation information of the user, and the like.

The content determination unit 66 determines the positive content to be presented to the user based on the user information registered in the database 64 and the like. The content determination unit 66 reproduces or generates the determined positive content and outputs the determined positive content to the output control unit 63.

(Estimation method of positive state)
FIG. 3 is a diagram showing an example of a method of estimating a positive state by the emotion estimation unit 61.

The emotion estimation unit 61 estimates whether or not the user is in a positive state based on at least one of the user's biological information, the user's behavioral status, and the external environmental information.

The emotion estimation unit 61 estimates whether or not the user is in a positive state based on the user's biological information, for example, information such as an increase in heart rate, a smile degree, or a state of gaze.

When the emotion estimation unit 61 uses the increase in the heart rate, the user is positive based on, for example, that the difference from the predetermined reference value is equal to or more than a certain value or exceeds the predetermined reference value for a certain period of time. Presumed to be in a state. At this time, the reference value may be defined based on the average value of the user or the measured value at a specific timing such as when waking up, or may be the average value of a plurality of users or a value defined by the information presentation system 1.

The emotion estimation unit 61 estimates that the user is in a positive state when the smile degree / laughter / tone is used, for example, when the facial expression is a smile and the number of laughter in a certain period of time is equal to or more than the reference value. Further, the emotion estimation unit 61 estimates that the user is in a positive state when the difference between the voice tone and the reference value of the tone is equal to or greater than the reference Hz.

The emotion estimation unit 61 estimates that the user is in a positive state when the state of the line of sight is used, for example, when the time when the line of sight does not point downward continues for a certain second or longer.

Further, the emotion estimation unit 61 is in a positive state of the user based on various states such as content browsing, sentence creation, utterance state, communication state, exercise state, and body movement state as the user's behavioral state. Estimate whether or not.

Specifically, when the emotion estimation unit 61 detects a positive term or image on the content while the user is browsing the Web content, it is estimated that the user is in a positive state. In addition, the emotion estimation unit 61 includes the user's situation (win / loss, etc.) in the game being played, the acquired item, the situation of the supporting team in the sports game being watched (win / loss, etc.), and the user's behavior information in entertainment. , Or, based on the walking tendency at that time, it may be estimated whether or not the user is in a positive state.

For example, the emotion estimation unit 61 estimates that the user is in a positive state, such as when the supporting team wins in reverse, or when the user meets a favorite character at a theme park and walks in a bouncy manner. ..

Further, the emotion estimation unit 61 estimates whether or not the user is in a positive state based on information such as weather, temperature, humidity, traffic condition, and environmental sound as external environmental information. For example, the emotion estimation unit 61 estimates whether or not the user is in a positive state when the train is not crowded or when the user's favorite music is played.

Specifically, the emotion estimation unit 61 estimates that the user is in a positive state when it is sunny, when the humidity is low, or when the temperature is appropriate.

It should be noted that a plurality of these estimation methods may be performed in parallel or may be performed in combination. Whether or not the state of the combination corresponds to the positive state for the user may be estimated using the learning result based on the data accumulated in the past.

(Operation of information presentation system)
FIG. 4 is a flowchart illustrating the information presentation process of the information presentation system 1.

Note that, in FIG. 4, the processing of the input device 11 is shown in combination with the processing of the information processing device 12.

In addition, the following will explain an example in which the user is watching the content being broadcast on TV as an example of the action.

In step S11, the sensor unit 31 of the input device 11 recognizes the room and the external environment, and outputs the external environment information indicating the external environment obtained as a result of the recognition to the information processing device 12.

In step S12, the sensor unit 32 of the input device 11 recognizes various information of the user and grasps the behavior. The sensor unit 32 outputs the user's biological information and the user's behavior status information obtained as a result of recognition and grasp to the information processing device 12.

In step S13, the emotion estimation unit 61 of the information processing apparatus 12 is based on at least one of the external environment information supplied from the input device 11, the biometric information of the user, and the behavioral status information of the user, and the emotion of the user. Estimate (positive state).

In step S14, the emotion estimation unit 61 determines whether or not the user is in a positive state. If it is determined in step S14 that the user is not in the positive state, the process proceeds to step S15.

In step S15, the content determination unit 66 determines positive content based on the user information registered in the database 64, reproduces or generates the determined positive content, and outputs the determined positive content to the output control unit 63. The output control unit 63 controls the presentation of the positive content by outputting the positive content supplied from the content determination unit 66 to a predetermined presentation device in the output device 13.

In step S31, the presentation device in the output device 13 presents the positive content supplied by the output control unit 63. The time for presenting the positive content may be a predetermined time set in advance, or may be until it is determined in the next step S14 that the positive content is in the positive state.

After the process of step S15, the process returns to step S11, and the subsequent processes are repeated.

If it is determined in step S14 that the user is in a positive state, the process proceeds to step S16.

In step S16, the task generation unit 62 determines the content of the option task. For example, the task generation unit 62 determines the content of the question (including the option) in the option task.

In step S17, the task generation unit 62 determines the device to be presented.

In step S18, the task generation unit 62 generates an option task based on the content of the determined option task and the device to be presented, and outputs the generated option task to the output control unit 63.

The processing of steps S16 to S18 is performed based on the external environment information supplied from the input device 11, the biometric information of the user, the behavior status information of the user, the user information registered in the database 64, and the like.

In step S19, the output control unit 63 waits until it is determined that it is time to present the option task. If it is determined in step S19 that it is time to present the option task, the process proceeds to step S20.

In step S20, the output control unit 63 controls the presentation of the option task by outputting the option task to the presentation device determined as the device to be presented in step S17 among the output devices 13.

In step S32, the presentation device of the output device 13 presents an option task.

The user starts the option task in response to the presentation of the option task in the output device 13.

In step S21, the sensor unit 33 of the input device 11 acquires the operation information from the user, and outputs the acquired operation information to the information processing device 12.

In step S22, the database update unit 65 of the information processing apparatus 12 registers the response corresponding to the user's operation information in the database 64 as user information such as user attribute information or user preference information. This response is, for example, transmitted by the output control unit 63 to the server of the corresponding company via the network as the answer result of the questionnaire from the company or the like.

As described above, when the positive state of the user who is watching TV is estimated, the option task is presented to the user. Since the user is in a positive state, it is estimated that the probability of responding to the presented choice task is high. That is, in the information presentation system 1, it is expected that the user's answer to the question including the choice can be obtained promptly and surely by utilizing the user's positive state.

(Contents of choice task)
The contents of the option task presented to the user include, for example, the following three contents.

1. The content of the option task is not limited in the presentation timing, but is what the information presentation system 1 wants the user to answer, or what the user wants to do.

For example, the content of the option task may be for acquiring the user's subjective data, or for confirming the user's To Do task or intention by the system. The confirmation of the user's intention by the information presentation system 1 includes, for example, confirmation of a person to whom the information presentation system 1 responds in the background to an incoming call or e-mail notification.

The user's subjective data includes (1) subjective data related to health (physical condition and mental state) such as physical condition and mood, (2) subjective data related to presented content / presented service, (3) advertising / marketing purpose, etc. There is subjective data in.

(1) Subjective data on health such as physical condition and mood are based on optional tasks such as "whether you slept", "how you are feeling now", "whether you are frustrated", and "whether you are anxious". To be acquired. These health questions may be, for example, based on stress check items based on the Industrial Safety and Health Act or various psychological indicators.

In this case, when biometric information (heartbeat, sweating, brain wave, etc.) is acquired by the contact sensor, camera, microphone, etc. constituting the sensor unit 32, the biometric information and this option task are acquired. It is also possible to compare it with subjective data.

(2) Subjective data related to the presented content / presented service includes the preference and evaluation of the content presented to the user, the evaluation of the quality of the service presented to the user, and the like. These subjective data are acquired and used by the information presentation system 1 as feedback information.

For example, if the service presented to the user is a music distribution service or a user behavior management service, the user's subjective data is acquired as feedback information at a fixed point (for example, once a day or once a week). By using the service, the service will be more personalized.

(3) Subjective data for advertising and marketing purposes is acquired regardless of the content presented to the user. For example, in the case of automobile marketing, it is possible to acquire information on a user's favorite vehicle type by presenting an option task that includes a plurality of vehicle types as options. In this case, the selection result can be obtained as a marketing survey result and sent to the corresponding server, or the selection presentation itself can function as an advertisement (for example, improving the user's awareness of the presented vehicle type). can.

2. The content of the choice task is the content that the user is interested in. For example, the content is closely related to the content that matches the user's taste and the content that the user is viewing. Specifically, when the user is watching a sports match, the content of the option task may be, for example, a player's popularity voting questionnaire. Further, when the user is watching a news program, the content of the option task may be, for example, an opinion poll.

3. As for the content of the option task, the act of selecting itself is important, but the selected result may be an incorrect answer. That is, a less important content such that the selected result can be corrected later is suitable for the option task. The content of the choice task is, for example, what time is the wake-up time tomorrow? The contents themselves, such as weekday settings and holiday settings, are not very important and may be modified later.

Choice tasks that satisfy these conditions are generated based on the user's attribute information, the content of the content that the user views, and the time information.

FIG. 5 is a diagram showing an example of presenting an option task.

FIG. 5 shows an example of presentation by voice.

In FIG. 5, the voice presentation device 42 presents to the user an optional task with the content of "Which of XXX or AAA will you go first tomorrow?". In this case, three options are assumed: "XXX", "AAA", and "Stop both".

For example, when the user responds with "XXX kana" to the presented option task, the sensor unit 33 detects a voice indicating the user's response and outputs it to the information processing apparatus 12. The database update unit 65 updates the user's to-do list of the database 64 based on the user's response, and presents the state of the corresponding item (plan) with priority, for example, or processes it in the background. Move to such a state.

The option task of FIG. 5 is for confirming the intention of the user, is what the user wants to perform in the user's to-do list, and the information presentation system 1 responds to the user. It's also what I want. That is, the presentation example is the option task of the first content described above.

In the example of FIG. 5, the TV, which is the visual presentation device 41, is shown near the user, but when the user is watching the contents of the TV, the visual presentation device 41 is presented with the above-mentioned option task. You may let it.

(Timing of presentation of alternative tasks)
FIG. 6 is a diagram showing an example of the presentation timing of the option task.

In the example of FIG. 6, when the user is estimated to be in a positive state while viewing the content on the TV which is the visual presentation device 41, the options are selected according to the degree of the positive state (hereinafter, also referred to as the positive degree). An example of changing the presentation timing of a task is shown.

The user is watching the content in which a dinosaur appears in the city on a TV, which is a visual presentation device 41, for example. The arrow shown on the right side of the user indicates the degree of positiveness of the user estimated by the information presentation system 1, and the degree of positiveness increases from the bottom to the top.

When the degree of positiveness of the user is large, the information presentation system 1 causes the user to present the option task in the corner of the screen even while the user is viewing the content. At that time, the option task is composed of, for example, a task having a large number of options, a task having a plurality of screens, or a task in which the options are divided into a plurality of screens and have screen transitions.

On the other hand, when the degree of positiveness of the user is small, the information presentation system 1 causes the option task to be presented at a well-separated timing such as the timing of entering the CM, the timing of ending the content, or the timing of turning off the power. At that time, the choice task is composed of, for example, a task consisting of two choices of Yes / No, or a task having few choices such as a task of notification and a task of confirmation of OK / NG.

Further, when the degree of positiveness is negative, that is, when the user is estimated to be in a negative state, the above-mentioned positive content is presented so as to direct the user to the positive state.

Note that the presentation time of the option task may be within the time during which the user's positive state continues. However, since the user makes a selection in a positive state, the answer can actually be answered in a few tens of seconds, for example.

Further, the option task may be continuously presented as long as the positive state of the user does not suddenly drop. For example, when there are a plurality of questions to be asked to the user, the option task may be continuously presented at the timing when the user can be presented, as long as the positive state of the user continues. The longest presentation time is the time during which the user's positive state continues.

As described above, in this technology, the presentation of the option task to the user is controlled according to the degree of positiveness of the user.

This makes it possible to prompt the user to quickly answer the options while maintaining the positive state of the user.

<2. Expansion example 1 (questionnaire conducted while watching a game)>
The information presentation system 1 of FIG. 1 described above presents an option task including a questionnaire related to the game when the situation of the game is calm and the user is estimated to be in a positive state while watching the game such as sports. It also functions as an application to let you. The extended example 1 will be described with reference to FIG. 7.

FIG. 7 is a diagram showing an example of presenting an option task in the extended example 1.

FIG. 7 shows an example of presenting an option task including a questionnaire related to a match when the situation of the match is settled and the user is estimated to be in a positive state while watching the match.

The user is watching a soccer game, for example, at the game venue. If it is estimated that the user is in a positive state at the timing when the game development is settled (for example, half-time time) after the score is given to the team supported by the user and the game is excited, the task generation unit 62 will perform the task generation unit 62. Generate a choice task that includes a match-related survey.

The game venue is equipped with a visual presentation device 41 consisting of a large-sized display. The output control unit 63 causes the visual presentation device 41 of the match venue to present "What is today's MVP? A: XXX, B: RRR, vote on your smartphone!" As an optional task including a questionnaire related to the match. ..

The user who sees the option task selects A or B by using the smart phone which is the sensor unit 33 owned by the user.

For example, when the user responds with "A: XXX" to the presented option task, the sensor unit 33 detects the voice indicating the user's response and outputs it to the information processing apparatus 12. At that time, the database update unit 65 updates the user information of the database 64 based on the user's response, and the output control unit 63 transmits the questionnaire information to the corresponding server via the network.

Here, when the option task is generated, the task generation unit 62 generates the option task so as to present in order from the option task including the question having the highest priority for which the response rate is to be increased. As a result, even if a part of the user leaves in the middle, the response rate to the high-priority question can be increased.

In the example of FIG. 7, an example of presenting an option task on the display of the match venue is shown, but the visual presentation device 41 to be presented is a smartphone, a tablet terminal, a personal computer, a TV, or an AR (augmented reality). / Augmented Reality) It may be a device owned by each user such as a device.

Further, in the example of FIG. 7, an example of watching a game at a game venue is shown, but it is not limited to a sports game, but may be an event or a live performance. Further, the content such as a match or an event may be an online video or video distribution content. At that time, for example, the option task is presented superimposed on the content.

As described above, in the present technology, when it is estimated that the development of the content is calm and the user is in a positive state while viewing the content, an option task including a questionnaire related to the content is presented. This makes it possible to increase the immediacy of the user's response.

<3. Extension example 2 (presentation based on a to-do list)>
The information presentation system 1 of FIG. 1 described above is an application that promotes a user's action by generating an option task based on a to-do list or a schedule in which the action schedule of the user registered in the database 64 or the like is registered. Also works. An extended example 2 will be described with reference to FIGS. 8 and 9.

FIG. 8 is a diagram illustrating expansion example 2.

FIG. 8 shows an example in which music is played when it is determined that the user is not in the positive state in the extended example 2.

In the information presentation system 1, when it is determined that the user is not in a positive state in daily life, as shown in FIG. 8, for example, from the voice presentation device 42, as an example of the above-mentioned positive content, the user You can play your favorite music.

As described above, the positive content is determined based on the user information registered in the database 64 and the like.

In response to this, when the user's state changes to a positive state and it is determined that the user is in the positive state, the task generation unit 62 may further intervene (estimated to allow interrupts). It is determined whether or not it is in the state.

FIG. 9 is a diagram showing an example of presenting an option task in the extended example 2.

In FIG. 9, when it is determined that the user is in a positive state and further, it is determined that the user is in a state where the user may intervene, an example of presenting an option task generated based on the user's to-do list. It is shown.

When it is determined that the user is in a positive state, the task generation unit 62 first refers to the user's behavioral status and the like, and determines whether or not the user is in a state where intervention is acceptable.

When it is determined that the user is in a state where the user may intervene, such as when the user is not busy and there is room for movement, the task generation unit 62 confirms the user's to-do list registered in the database 64. In order to do so, we will generate a choice task with two choices: "By the way, I had to decide A and B. Which would you like?"

The output control unit 63 controls to output the generated option task from the smart speaker which is the voice presentation device 42. As a result, the voice presentation device 42 presents the option task by the voice "By the way, it was necessary to decide A and B. Which would you like?"

For example, when the user responds to the presented option task with "A", the sensor unit 33 detects the voice indicating the user's response and outputs it to the information processing apparatus 12. The database update unit 65 updates the user's to-do list of the database 64 based on the user's response, and as described above, presents the state of the item preferentially, or processes it in the background. Move to a state such as.

Note that, in FIG. 9, the task is an option task for confirming the to-do list, but it may be an option task consisting of proposals for the user's next action, which is generated based on user information or the like.

In addition, if the user is in a positive state and the user is allowed to intervene, the option task may be presented even if it is before the original presentation timing (determined time) in the to-do list. good. That is, since the option task is presented at the timing when the user is in a positive state and may intervene, the user can respond more quickly and move to the next action.

Conversely, the choice task is later than the original presentation timing if the user is not in a positive state or the user is busy at the original presentation timing (fixed time) in the to-do list. It may be presented. In this case as well, since the user is in a positive state and the option task is presented at the timing when the user may intervene, the user can answer more quickly and move to the next action.

As described above, in this technology, when the user is in a positive state and it is time to intervene, the option task is presented based on the user information (user's to-do list). As a result, the alternative task can be presented naturally without burdening the user.

<4. Others>
