The emotion information to which the destination information is attached is transmitted and transmitted by the communication unit 501.
Next, a specific example of analysis processing by the analysis unit 504 will be described.

[First example]
The analysis unit 504 acquires the statistical value of the biological information included in the record 91 having the same content ID and substantially the same acquisition date and time as emotion information. The statistical value is a value such as a maximum value, a minimum value, an average value, or a mode value. For example, the analysis unit 504 may acquire a time series of statistical values from the current time to a predetermined time as emotion information.
The transmission control unit 505 selects the terminal device 10 or the television receiver 30 of the user who is viewing the content represented by the content ID as a transmission destination of the statistical value (emotional information) corresponding to each content ID. Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this manner, the user can share the emotion information of the other person who is viewing the same content as the other person with the other person. Therefore, for example, it is possible to confirm whether or not the other person is also surprised at the timing when he / she is surprised, and it is possible to sympathize with the other person.

[Second example]
The analysis unit 504 may acquire biometric information of one or more users as emotion information among the biometric information included in the record 91 having the same content ID. For example, biometric information of a performer of content may be acquired as emotion information. The analysis unit 504 may acquire a time series of biological information of one or more users as emotion information.
The transmission control unit 505 selects the terminal device 10 or the television receiver 30 of the user who is viewing the content represented by the content ID as the transmission destination of the emotion information corresponding to each content ID. Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this way, the user can acquire the emotion information of others who are viewing the same content as the user. In particular, when the performer's biometric information is acquired, the performer's biometric information can be shared with others who are viewing the same content as the performer. Therefore, for example, it is possible to confirm whether or not another person (for example, a performer) is also surprised at the timing when he / she is surprised, and can empathize with the other person.

[Third example]
The analysis unit 504 calculates the degree of synchronization between the first user and the second user based on the biometric information included in the record 91 having the same content ID. The analysis unit 504 handles the calculated value of the degree of synchronization as emotion information.
The degree of synchronization includes a time change of biological information (hereinafter referred to as “first biological information”) for the first user and a time change of biological information (hereinafter referred to as “second biological information”) for the second user. It is a value representing the degree of similarity. As the degree of synchronization is higher, the time change of the first biological information and the time change of the second biological information are more similar. As the degree of synchronization is lower, the time change of the first biological information and the time change of the second biological information are different.

  Hereinafter, a specific example of a method for calculating the degree of synchronization will be described. The analysis unit 504 includes the first biological information at the first timing (for example, the time when the latest biological information is acquired) and the second timing (for example, the time when the latest previous biological information is acquired). The difference with 1 biological information is calculated. The analysis unit 504 calculates a difference between the second biological information at the first timing and the second biological information at the second timing. Then, the analysis unit 504 determines that the degree of synchronization is higher as the difference between the two calculated differences is smaller. On the other hand, the analysis unit 504 determines that the degree of synchronization is lower as the difference between the two calculated differences is larger. The analysis unit 504 may determine the degree of synchronization using a predetermined threshold. For example, when the difference between the two differences is less than the threshold, the analysis unit 504 may determine that the first user and the second user are synchronized. When the difference between the two differences is equal to or greater than the threshold, the analysis unit 504 may determine that the first user and the second user are not synchronized.

  The transmission control unit 505 selects the terminal device 10 or the television receiver 30 of the user whose biometric information is used when calculating the degree of synchronization as a transmission destination of the degree of synchronization (emotional information) corresponding to each content ID. . Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this way, the user can share emotion information with others who are viewing the same content as the user. Therefore, for example, it is possible to confirm whether or not the other person is also surprised at the timing when he / she is surprised, and it is possible to sympathize with the other person. Further, by determining the degree of synchronization based on the difference instead of the absolute value of the biological information, it is possible to determine the degree of synchronization more accurately while suppressing the influence of individual differences in the biological information.

[Fourth example]
The analysis unit 504 determines whether the first user and the second user are synchronized at a plurality of consecutive timings, as in the analysis process of the third example. When the determination result that the synchronization is performed is continuously obtained for a predetermined time or longer, the analysis unit 504 outputs the determination result that the synchronization is performed (synchronization determination result) as emotion information.
The transmission control unit 505 selects, as the transmission destination of the synchronization determination result (emotion information) corresponding to each content ID, the user terminal device 10 or the television receiver 30 whose biometric information is used when calculating the degree of synchronization. To do. Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this way, the user can share emotion information with others who are viewing the same content as the user. Therefore, for example, it is possible to confirm whether or not the change in one's own emotion is similar to the change in another's emotion, and it is possible to sympathize with the other person.

[Fifth Example]
The analysis unit 504 calculates the degree of synchronization between the first user and the second user based on the biometric information included in the record 91 having the same content ID. The analysis unit 504 handles the calculated value of the degree of synchronization as emotion information.
The analysis unit 504 generates a graph representing temporal changes in the biological information of the first user and the second user. The analysis unit 504 calculates the similarity between the graph of the biometric information of the first user and the graph of the biometric information of the second user by performing pattern matching processing. Any algorithm may be used to calculate the similarity. For example, SSD (Sum of Squared Difference), SAD (Sum of Absolute Difference), NCC (Normalized Cross-Correlation), or the like may be used.
The transmission control unit 505 selects, as the transmission destination of the synchronization determination result (emotion information) corresponding to each content ID, the user terminal device 10 or the television receiver 30 whose biometric information is used when calculating the degree of synchronization. To do. Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this way, the user can share emotion information with others who are viewing the same content as the user. Therefore, for example, it is possible to confirm whether or not the change in one's own emotion is similar to the change in another's emotion, and it is possible to sympathize with the other person.

[Sixth example]
The analysis unit 504 calculates the degree of synchronization between the first user and the second user based on the biometric information included in the record 91 having the same content ID. The analysis unit 504 handles the calculated value of the degree of synchronization as emotion information.
The analysis unit 504 generates a graph representing temporal changes in the biological information of the first user and the second user. The analysis unit 504 counts the number of times that the graph of the first user and the graph of the second user intersect (hereinafter referred to as “number of times of intersection”). The analysis unit 504 determines that the greater the number of crossings, the higher the degree of synchronization. The analysis unit 504 determines that the degree of synchronization is lower as the number of crossings is smaller.
The transmission control unit 505 selects the terminal device 10 or the television receiver 30 of the user whose biometric information is used when calculating the degree of synchronization as a transmission destination of the degree of synchronization (emotional information) corresponding to each content ID. . Upon receiving the emotion information, the terminal device 10 and the television receiver 30 provide the emotion information to the user by displaying the emotion information on the screen. The terminal device 10 and the television receiver 30 may display the biometric information of the user on the screen together with the received emotion information.

  By performing the analysis process in this way, the user can share emotion information with others who are viewing the same content as the user. Therefore, for example, it is possible to confirm whether or not the change in one's own emotion is similar to the change in another's emotion, and it is possible to sympathize with the other person.

  The first to sixth examples described above are only specific examples of analysis processing. Therefore, the analysis process may be performed by a process different from the first example to the sixth example. The timing at which the analysis process is performed may be a predetermined time, a predetermined time interval, or a predetermined timing determined for each content.

  As described above, in the information acquisition system 1, the emotion information related to the content being viewed by the user is output by the terminal device 10 or the television receiver 30. Therefore, the user can know whether or not he / she can sympathize with others (for example, performers, friends, and others who are viewing the same content). Therefore, it is possible to raise the mood together with others and to enjoy the content even more. In addition, it is possible to call the user a sense of familiarity and interest in the performers. In addition, the degree of attachment to the content can be increased. In particular, when determination of the degree of synchronization is performed as analysis processing, it is possible to provide a game based on the presence or absence of synchronization and the level of synchronization. Further, by using the data stored in the sensor data storage unit 503 of the sensor server 50, it is possible to determine the effect of the effect for each content. Moreover, it becomes possible to perform more accurate marketing by analyzing using the said data.

<Modification>
(1. Regarding the biological information sensor 20)
The biological information sensor 20 may be configured using a pressure gauge. In this case, the biological information sensor 20 may acquire pressure generated by being held by the user's hand as biological information.
The biological information sensor 20 may be configured using a sensor that measures a distance. In this case, the biological information sensor 20 may acquire information regarding the degree to which the user is facing forward as biological information by measuring the distance between the front surface of the user and the floor surface, the desk surface, or the like.

The biological information sensor 20 may be configured using a humidity sensor. In this case, the biological information sensor 20 may acquire humidity as information regarding the amount of sweat on the palm by being held by the user's hand. In this case, humidity is biological information.
The biological information sensor 20 may be configured using a camera and a facial expression recognition device. In this case, the biological information sensor 20 may acquire information regarding the degree of smile as the biological information by analyzing the face of the user imaged by the camera.

  The biological information sensor 20 may be configured using an acceleration sensor. In this case, the biological information sensor 20 may acquire acceleration as information on the degree of movement of the user's body by being attached to the user's body. For example, the acceleration sensor can acquire the user's excitement level as biological information by measuring the acceleration caused by the movement of the arm.

(2. Correction of acquisition date and time)
The data accumulation control unit 502 may correct the acquisition date and time according to the user environment when recording the received biological information in the sensor data storage unit 503. For example, when the user is watching a television broadcast using a one-segment tuner, the displayed video is delayed compared to when the user is watching a television broadcast using the television receiver 30. By correcting the acquisition date and time by the data storage control unit 502, it is possible to eliminate the above-described delay and perform analysis processing based on biological information acquired when viewing the same scene.

  Such correction of the acquisition date / time may be performed by the analysis unit 504 instead of the data accumulation control unit 502. That is, the correction unit that corrects the acquisition date and time may be provided in the data accumulation control unit 502 or may be provided in the analysis unit 504. For example, when the analysis process is performed using the time series of the biological information of the first user and the time series of the biological information of the second user, the analysis unit 504 performs correction by matching the phases of the two time series waveforms. May be performed. During this correction, the two waveforms are shifted in the time axis direction. Specifically, the analysis unit 504 may perform correction by matching the positions of the vertices (for example, the maximum value and the minimum value) of two time-series waveforms, and the difference between the two waveforms is minimized. Correction may be performed by shifting in this manner.

(3. About the video server)
The information acquisition system 1 may further include a video server. The video server stores a plurality of video data. The video server 60 distributes video data via the network 40 in response to a user request. The terminal device 10 and the television receiver 30 receive video data from the video server 60 via the network 40. The terminal device 10 and the television receiver 30 generate a video based on the received video data and display it on the screen.

  When comprised in this way, the terminal device 10 acquires the reproduction | regeneration time (elapsed time after reproduction | regeneration start) of the video data at the time of biometric information being acquired as information regarding biometric information. When the terminal apparatus 10 transmits the biological information to the sensor server 50, the terminal apparatus 10 also transmits the reproduction time. The analysis unit 504 performs an analysis process based on the reproduction time, not the acquisition date and time. For example, in the first example, the analysis unit 504 uses, for example, a time series of statistical values from a playback start time (playback time = 0) to a predetermined playback time (for example, playback time = 20 minutes) as emotion information. You may get it. With this configuration, it is possible to share emotions related to content viewing even when the video playback timing varies from person to person as in video on demand.

(4. Display method)
The emotion information may be displayed on a browser layer overlaid on the content video on the screen of the television receiver 30.
The emotion information may be displayed on the screen of the terminal device 10.
The emotion information may be displayed in a graph format as time series information.
Emotion information may be displayed in other manners.

(5. Contents)
The television receiver 30 may receive video data of an IP multicast broadcast service using IP multicast or IPv6. The television receiver 30 may receive video data transmitted by streaming.
Further, the content may be played back by a device other than the television receiver 30. For example, the content may be content that is played back on digital signage. In this case, a digital signage display device may be used instead of the television receiver 30.
The content may be a live performance at a live venue such as a concert, a live theater, a live performance, a live talk, a live panel discussion, a live conte.

(6. Apparatus provided with analysis unit 504)
In the information acquisition system 1 described above, the analysis unit 504 is provided in the sensor server 50. However, the analysis unit 504 may be provided in another device.

  For example, the analysis unit 504 may be included in the terminal device 10. In this case, the terminal device 10 requests the sensor server 50 for a biometric information record necessary for the analysis process. The transmission control unit 505 of the sensor server 50 reads out the requested biological information record from the sensor data storage unit 503 and transmits the biological information record to the request source (terminal device 10). The analysis unit 504 of the terminal device 10 performs analysis processing using the biological information record acquired from the sensor server 50.

  For example, the analysis unit 504 may be provided in the television receiver 30. In this case, the television receiver 30 requests the sensor server 50 for a biometric information record necessary for the analysis process. The transmission control unit 505 of the sensor server 50 reads out the requested biometric information record from the sensor data storage unit 503 and transmits the biometric information record to the request source (the television receiver 30).
