The body fluid detection device 1 detects a user's body fluid (for example, tears or sweat) and transmits the detection information to the user terminal 2 as sensor data. The user terminal 2 transfers the sensor data to the information processing server 4 via the network 3. The information processing server 4 estimates the user's emotion (for example, the degree of impression or excitement) based on the sensor data transferred from the user terminal 2. Then, based on the estimation result, content data is acquired from the content server 5 via the network 3, and the content data is transmitted to the user terminal 2 via the network 3.

Hereinafter, the configurations of the body fluid detection device 1, the user terminal 2, and the information processing server 4 will be described in detail.
First, the body fluid detection device 1 includes a sensor unit 10A and a signal processing unit 20A connected to the sensor unit 10A. The sensor unit 10A is used when a user wipes tears, and includes a device manufactured in a cloth shape such as a handkerchief or a hand towel. The signal processing unit 20A is formed of, for example, a strap or key holder type device fixed to the end of the sensor unit 10A.

  The sensor unit 10A may be a paper-like one such as tissue paper in addition to the cloth-like one. The signal processing unit 20A may be affixed or sewn to the cloth-like device of the sensor unit 10A, or may be provided on the cloth fiber itself.

  The user terminal 2 includes a mobile terminal such as a mobile phone, a smartphone, a tablet terminal, or a wearable terminal, for example, and in addition to a communication interface that transmits and receives data to and from the information processing server 4 via the network 3, the sensor In order to receive the sensor data transmitted from the unit 10A, a data communication interface using weak or low power represented by bluetooth (registered trademark), Zigbee (registered trademark) or the like is provided.

  The transfer of the sensor data from the signal processing unit 20A to the user terminal is not limited to wireless, and may be performed by directly connecting a wired signal cable such as a USB cable and USB terminals. The sensor data may be output from the signal processing unit 20A in real time. However, a memory for storing the sensor data is provided in the signal processing unit 20A, and the sensor data stored in the memory is read to read out the user terminal or the user data. You may make it transfer collectively to information processing apparatuses, such as a server. Furthermore, a storage medium removable from the signal processing unit 20A may be used as a memory, and the sensor data may be transferred to an information processing apparatus such as a user terminal or a server using the storage medium.

The information processing server 4 is composed of a cloud server, for example, and is configured as follows. FIG. 2 is a block diagram showing the functional configuration.
That is, the information processing server 4 includes a control unit 41, a storage unit 42, and a communication interface unit 43. The communication interface unit 43 performs data communication between the user terminal 2 and the content server 5 via the network 3 under the control of the control unit 41.

  The storage unit 42 uses a storage medium that can be written and read as needed, such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) as a storage medium, and is necessary for implementing the first embodiment. As storage areas, a sensor data storage unit 421, a user state storage unit 422, and a collective state storage unit 423 are provided.

  The sensor data storage unit 421 is used for storing sensor data transmitted from the body fluid detection device 1. The user state storage unit 422 is used to store information representing an emotion estimation result for each user in association with the user ID. The group state storage unit 423 is used to store information representing an estimation result of emotions of a group to which a plurality of users existing in the same time zone in a common environment belong.

  The control unit 41 includes a CPU (Central Processing Unit) and a working memory. As a control function necessary for implementing the first embodiment, a sensor data collection control unit 411, a user state estimation processing unit 412, The estimation result notification control unit 413 and the collective state estimation processing unit 414 are provided. These control functions are realized by causing the CPU to execute a program stored in a program memory (not shown).

  The sensor data collection control unit 411 collects sensor data from the user terminal 2 of each user, associates the collected sensor data with the corresponding user identification information (user ID), and the sensor data storage unit 421. The process to memorize is performed.

  The user state estimation processing unit 412 reads the sensor data for each user ID from the sensor data storage unit 421, and extracts information representing the time or period when the user shed tears or sweat from the read sensor data. To do. Then, the extracted time or period is associated with the scene of the content that the user was appreciating at that time, thereby calculating the degree of impression or excitement of the user with respect to the content, and calculating the result of the user's As information representing the state, a process of storing in the user state storage unit 422 in association with the user ID is performed.

  The estimation result notification control unit 413 acquires similar or related content from the content server 5 based on the information indicating the user state stored in the user state storage unit 422, and the user terminal of the user 2 is processed.

  The collective state estimation processing unit 414 reads, from the user state storage unit 422, information representing the degree of impression of a plurality of users belonging to a predefined group in the same time zone. Then, based on the read information indicating the degree of impression or excitement of the plurality of users, the tendency of impression or excitement as a group for the content that the plurality of users watched in the same time zone is statistically calculated. A process of obtaining by calculation and storing the calculation result in the collective state storage unit 423 in association with the identification information of the content is performed.

  Next, the configuration of the sensor unit 10A and the signal processing unit 20A of the body fluid detection device 1 will be described in more detail. FIG. 3 is a diagram showing the configuration.

  10 A of sensor units consist of what laminated | stacked the 1st cloth-like device 11 and the 2nd cloth-like device 12 on the sandwich form on both sides of the cloth body (henceforth an insulating sheet) 13 which has insulation. . Both the first cloth-like device 11 and the second cloth-like device 12 are formed on almost the entire surface of one surface of an insulating cloth body (insulating cloth body) 111, 121 serving as a base, for example, as shown in FIG. As shown, planar patterns (conductive patterns) 112a and 122a having conductivity are formed.

  That is, the sensor unit 10A has a five-layer structure in which the insulating cloth bodies 111 and 121, the conductive patterns 112a and 122a, and the insulating sheet 13 are overlapped, and both layers are hygroscopic and quick. Materials that have both dryness are used.

  On the other hand, the signal processing unit 20A is formed by integrating a resistance value measuring unit 21a and a communication unit 22 into a module. The resistance value measuring unit 21a continuously or intermittently measures the resistance value between the conductive pattern 112a of the first cloth-like device 11 and the conductive pattern 122a of the second cloth-like device 12. As a method for measuring the resistance value, for example, a Wheatstone bridge can be considered, but the resistance value is not limited thereto. Then, the resistance value measurement unit 21a compares the measured resistance value with threshold values Th1 and Th2 set in advance according to the type of body fluid, and the time when the resistance value falls below the threshold values Th1 and Th2. Alternatively, information indicating the period and information indicating the type of body fluid determined by which threshold value Th1 or Th2 is below are included in the sensor data and output.

  The communication unit 22 uses the data communication interface using weak or low power represented by bluetooth (registered trademark) or Zigbee (registered trademark) as an antenna for the sensor data output from the resistance value measuring unit 21a. 23 to the user terminal 2.

(Operation)
Now, for example, assume that a user is watching video content (movie or drama) at home or in a movie theater. Although the user has the body fluid detection device 1 instead of a handkerchief or a hand towel, the body fluid detection device 1 is not used because it usually does not shed tears or sweat in a normal scene. For this reason, the resistance value measured by the resistance value measuring unit 21a of the body fluid detection device 1 is equal to or greater than the threshold value Th1, for example, as shown in FIG.

  On the other hand, for example, it is assumed that a user sheds tears in a sad scene of a movie and wipes it with the sensor unit 10A. If it does so, a tear will permeate into each internal layer from one side of the insulating cloth bodies 111 and 121 of 10 A of sensor units, and will electrically short-circuit between the conductive pattern 112a and the conductive pattern 122a. Tears generally contain electrolytes such as sodium (NaCl) and potassium (KCl), and these electrolytes have specific electrical conductivity as shown in FIGS. 8 and 9, for example. For this reason, the resistance value measured in the resistance value measuring unit 21a decreases according to the conductivity of the tears.

  Then, based on the information indicating the resistance value range of “tears” measured in advance and stored in the table, for example, as shown in FIG. If it is set to be slightly higher than the maximum value of the range, the resistance value between the conductive patterns 112a and 122a short-circuited by the tear is lower than a threshold value Th1 as shown in FIG. 6, for example. In the resistance value measurement unit 21a, information indicating the time or period when the resistance value falls below the threshold value Th1 is generated. Then, sensor data including information indicating this time or period is transmitted from the communication unit 22.

  Similarly, for example, when a user excites sweat in an action scene of a movie and wipes it with the sensor unit 10A, the conductive patterns 112a and 122a of the sensor unit 10A are short-circuited by sweat, The resistance value falls below the threshold value Th2 set for detecting “sweat”. In this case, in the resistance value measuring unit 21a, information indicating the time or period when the resistance value falls below the threshold value Th2 is generated, and sensor data including information indicating the time or period is transmitted from the communication unit 22.

  Since threshold values Th1 and Th2 are set for each type of body fluid, that is, “tears” and “sweat”, the resistance value measurement unit 21a can determine not only the presence of body fluid but also the type of body fluid. it can. In this case, in addition to the information indicating the time or period when the body fluid is detected, the resistance value measurement unit 21a can transmit the sensor data including information indicating the type of the body fluid.

  The sensor data transmitted from the communication unit 22 is received by the user terminal 2 possessed by the user and transferred from the user terminal 2 to the information processing server 4 via the network 3.

  In the information processing server 4, the sensor data is received by the communication interface unit 43 and stored in the sensor data storage unit 421 under the control of the sensor data collection control unit 411. For example, when a movie or drama showing time or airing time ends, a sensor received from the sensor data storage unit 421 for each user at the time shown or airing time under the control of the user state estimation processing unit 412 Data is read out. Then, information indicating the time or period when the user shed tears or sweat is extracted from the sensor data, and the movie or drama scene that the user was watching at that time for the extracted time or period Are associated with each other.

  It is assumed that information on the content being screened or aired is acquired from a movie distributor or a broadcasting station, or stored in the information processing server 4 in advance. Then, the degree of impression or excitement of the user with respect to the movie or drama is calculated, and the calculation result is stored in the user state storage unit 422 in association with the user ID.

  Subsequently, in the information processing server 4, under the control of the estimation result notification control unit 413, identification information and impression or excitement of the movie or drama that the user has viewed from the user state storage unit 422 for each user. Information indicating the degree is read. Then, for example, based on the information indicating the degree of excitement or excitement, a similar or related movie or drama content with a high probability that the user will be impressed or excited is acquired from the content server 5, and the name and outline of the content are obtained. Information representing the above, or a sample video is distributed to the user terminal 2.

  Also, based on the information stored in the user status storage unit 422, a scene where tears or sweat are extracted from a plurality of contents that the user has viewed or watched in the past is extracted and distributed as a digest. Also good. By doing in this way, the user can effectively look back on the scenes in which tears or sweat shed in the content that the user has viewed or appreciated in the past.

  Further, in the information processing server 4, under the control of the collective state estimation processing unit 414, information indicating the degree of impression or excitement of a plurality of users belonging to a predefined group in the same time zone is the user state storage unit 422. Read from. For example, for each movie theater, information indicating the degree of excitement or excitement of a plurality of users who watched the movie at the same movie theater is read out. Then, based on the information indicating the degree of excitement or excitement of the plurality of read users, the tendency of impression or excitement as a group with respect to a movie viewed in the same time zone is calculated by statistical calculation, The calculation result is stored in the collective state storage unit 423. Information representing the degree of excitement or excitement in this group can be used to evaluate a movie.

(effect)
As described above in detail, in the first embodiment, the insulating cloth bodies 111 and 121, the conductive patterns 112a and 122a, and the insulating sheet 13 are overlapped to form a sensor unit 10A having a five-layer structure. The resistance value measurement unit 21a detects a decrease in resistance between the conductive patterns 112a and 122a when tears or sweat adheres to the unit 10A, and information indicating the detection time or period, and information indicating the type of body fluid Is transmitted from the communication unit 22.

  For this reason, sensor data for estimating the degree of emotion or excitement of a user when viewing content such as a movie or a drama is used for the user's natural action of wiping tears or sweat, and tears or sweat It is possible to detect the presence or absence of the resistance as a decrease in the resistance value. Therefore, the processing load of data analysis can be reduced, and it is possible to eliminate the user's psychological burden by eliminating the need for attaching the sensor to the body.

  Further, in the information processing server 4, based on information indicating the type of bodily fluid included in the sensor data sent from the bodily fluid detection device 1 and information indicating the detection time or period, the movie or drama being watched by the user It can be estimated in which scene the user was moved or excited.

  Furthermore, since the sensor data is relayed and transferred to the information processing server 4 by the user terminal 2 and the process of estimating the user's emotion is performed in the information processing server 4, for example, similarly in the body fluid detection device 1 or the user terminal 2. As compared with the case where the above estimation process is executed, the estimation process can be performed efficiently at high speed without affecting other processes.

  Further, in the information processing server 4, based on the estimation result of the degree of user excitement or excitement with respect to the movie or drama, information on contents such as other movies and dramas that have a high probability of giving the user excitement or excitement is obtained. Since the content is distributed to the user terminal 2, the user can acquire information on the content such as his / her favorite movie or drama without searching for it.

  Furthermore, by performing statistical processing based on information that represents the degree of excitement or excitement of multiple users who watched the same movie or drama during the same time period, not only individual users but also venues or households The degree of excitement or excitement of the viewed group can be quantified, and thereby it is possible to perform objective evaluation on a movie or drama by eliminating variation in evaluation among users.

Similarly, the second cloth-like device 12b also has a conductive pattern 122b having a comb-like shape formed on one surface of the insulating cloth body 121. However, the conductive patterns 112b and 122b are formed to be orthogonal to each other. As in the first embodiment, an insulating sheet is provided between the surface of the insulating cloth body 111 on which the conductive pattern 112b is formed and the surface of the insulating cloth body 121 on which the conductive pattern 122b is formed. 13 is interposed.
