[First Embodiment]
(Constitution)
FIG. 1 is a diagram showing an overall configuration of a state estimation system using a body fluid detection device according to a first embodiment of the present invention.
The state estimation system according to the first embodiment includes a body fluid detection device 1, a user terminal 2, an information processing server 4, and a content server 5. The body fluid detection device 1 detects a body fluid (for example, tears or sweat) of the user 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 a user's emotion (for example, degree of excitement or excitement) based on the sensor data transferred from the user terminal 2. Then, based on the estimation result, the 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 is made of a fabric-like device such as a handkerchief or a hand towel. The signal processing unit 20A is, for example, a strap or a key holder type device fixed to an end of the sensor unit 10A.

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

  The user terminal 2 includes, for example, a mobile terminal such as a mobile phone, a smartphone, a tablet terminal, or a wearable terminal, and includes, in addition to a communication interface for transmitting and receiving data to and from the information processing server 4 via the network 3, 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, but may be performed by directly connecting a wired signal cable such as a USB cable or USB terminals. The sensor data may be output from the signal processing unit 20A in real time. However, the signal processing unit 20A is provided with a memory for storing sensor data, and the sensor data stored in the memory is read and read from the user terminal or The information may be collectively transferred to an information processing device such as a server. Further, a storage medium detachable from the signal processing unit 20A may be used as a memory, and the sensor data may be transferred to an information processing device such as a user terminal or a server using the storage medium.

The information processing server 4 is composed of, for example, a cloud server, 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 such as a hard disk drive (HDD) or a solid state drive (SSD) that can be written and read at any time as a storage medium, and is necessary for carrying out the first embodiment. The storage area includes a sensor data storage unit 421, a user state storage unit 422, and a group state storage unit 423.

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

  The control unit 41 includes a CPU (Central Processing Unit) and a working memory, and includes a sensor data collection control unit 411, a user state estimation processing unit 412, and the like as control functions necessary for implementing the first embodiment. , An estimation result notification control unit 413 and a group state estimation processing unit 414. 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 stores the sensor data in the sensor data storage unit 421. Is performed.

  The user state estimation processing unit 412 reads the sensor data from the sensor data storage unit 421 for each user ID, and extracts information representing the time or period at which the user shed tears or sweat from the read sensor data. I do. Then, the extracted time or period is associated with the scene of the content that the user was watching at that time, whereby the degree of excitement or excitement of the user with respect to the content is calculated, and the calculation result is calculated by the user. A process for storing the information indicating the state 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 status stored in the user status storage unit 422, and 2 is performed.

  The group state estimation processing unit 414 reads, from the user state storage unit 422, information indicating the degree of impression of a plurality of users belonging to a group defined in advance in the same time zone. Then, based on the read information indicating the degree of the excitement or excitement of the plurality of users, the tendency of the excitement or excitement as a group with respect to the content viewed by the plurality of users at the same time is statistically calculated. The calculation is performed, and the calculation result is stored in the group status storage unit 423 in association with the identification information of the content.

  Next, the configurations 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.

  The sensor unit 10A is formed by stacking a first cloth-like device 11 and a second cloth-like device 12 in a sandwich manner with a cloth body (hereinafter, referred to as an insulating sheet) 13 having insulation properties. . Each of the first cloth-like device 11 and the second cloth-like device 12 covers almost one surface of one of insulating cloths (insulating cloths) 111 and 121 serving as a base, for example, as shown in FIG. As shown, a planar pattern (conductive pattern) 112a, 122a having conductivity is formed.

  That is, the sensor unit 10A has a five-layer structure in which the insulating cloths 111 and 121, the conductive patterns 112a and 122a, and the insulating sheet 13 are superimposed. A material having both dryness is used.

  On the other hand, the signal processing unit 20A is configured by integrating the resistance value measurement unit 21a and the communication unit 22 into a module. The resistance value measurement unit 21a continuously or intermittently measures a 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 of measuring the resistance value, for example, a Wheatstone bridge can be considered, but it is not limited to this. 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 the body fluid, and determines 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 the body fluid determined based on which of the threshold values Th1 and Th2 have fallen below are included in the sensor data and output.

  The communication unit 22 converts the sensor data output from the resistance value measurement unit 21a into an antenna using a data communication interface using weak or low power represented by bluetooth (registered trademark) or Zigbee (registered trademark). 23 has a function of transmitting to the user terminal 2.

(motion)
Now, for example, it is assumed that the user is watching video contents (movies and dramas) 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 in normal scenes because she usually does not shed tears or sweat. For this reason, the resistance value measured by the resistance value measurement unit 21a of the body fluid detection device 1 becomes equal to or greater than the threshold value Th1, for example, as shown in FIG. 4, and as a result, sensor data is not transmitted.

  On the other hand, for example, it is assumed that the user sheds tears in a sad scene of a movie and wipes it with the sensor unit 10A. Then, tears seep into one of the inner layers of the insulating cloths 111 and 121 of the sensor unit 10A, and electrically short-circuit the conductive pattern 112a and the conductive pattern 122a. Tears generally contain electrolytes such as sodium (NaCl) and potassium (KCl), and these electrolytes have an intrinsic conductivity as shown in FIGS. 8 and 9, for example. Therefore, the resistance value measured by the resistance value measurement unit 21a decreases according to the conductivity of the tear.

  Then, the threshold value Th1 for detecting tears is measured in advance as shown in FIG. 10, for example, based on the information indicating the resistance value range of “tears” stored in the table, 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 will fall below the threshold value Th1, for example, as shown in FIG. The resistance value measurement unit 21a generates information indicating a time or a period when the resistance value falls below the threshold value Th1. Then, the sensor data including information indicating the time or the period is transmitted from the communication unit 22.

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

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

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

  In the information processing server 4, under the control of the sensor data collection control unit 411, the sensor data is received by the communication interface unit 43 and stored in the sensor data storage unit 421. Then, for example, when the movie or drama show time or air time ends, under the control of the user state estimation processing unit 412, the sensor received at the show time or air time for each user from the sensor data storage unit 421. Data is read. Then, information indicating the time or period when the user tears or sweats is extracted from the sensor data, and the scene of the movie or drama that the user was watching at that time is extracted with respect to the extracted time or period. Is associated.

  It is assumed that the information of the content being shown or being broadcast is obtained from the distributor of the movie or the broadcasting station, or is stored in the information processing server 4 in advance. Then, the degree of excitement or excitement of the user with respect to the movie or the 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, from the user state storage unit 422, the identification information of the movie or drama watched by the user and the impression or excitement of the user for each user Information indicating the degree is read. Then, for example, based on the information indicating the degree of excitement or excitement, similar or related movie or drama content with a high probability of the user being impressed or excited is acquired from the content server 5, and the name or outline of this content is obtained. , Or a sample video is distributed to the user terminal 2.

  In addition, based on the information stored in the user state storage unit 422, among a plurality of contents that the user has watched or watched in the past, a scene in which tears or sweat has been extracted is extracted and distributed as a digest. Is also good. By doing so, the user can effectively look back on the scene in which tears or sweat has been seen in the content that he or she has viewed or watched in the past.

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

(effect)
As described in detail above, in the first embodiment, the sensor unit 10A having a five-layer structure is formed by superposing the insulating cloths 111 and 121, the conductive patterns 112a and 122a, and the insulating sheet 13 on each other. A decrease in resistance between the conductive patterns 112a and 122a when tears or sweat adheres to the unit 10A is detected by the resistance value measuring unit 21a, 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 excitement or excitement of the user when appreciating contents such as movies and dramas is used for the user's natural operation of wiping tears and sweat, and Can be detected as a decrease in the resistance value. Therefore, the processing load of data analysis can be reduced, and it becomes unnecessary to attach the sensor to the body, and it is possible to eliminate the psychological burden on the user.

  Further, in the information processing server 4, based on the information indicating the type of the body fluid and the information indicating the detection time or period included in the sensor data sent from the body fluid detection device 1, the user can view the movie or drama being watched by the user. It is possible to estimate in which scene the user was impressed or excited.

  Furthermore, since the sensor data is relayed and transferred to the information processing server 4 by the user terminal 2 and the processing of estimating the emotion of the user is performed in the information processing server 4, for example, the body fluid detecting device 1 or the user terminal 2 performs the same processing. As compared with the case where the estimation process of (1) is executed, the estimation can be performed quickly and efficiently without affecting other processes.

  Further, in the information processing server 4, based on the estimation result of the degree of the user's impression or excitement with respect to the movie or the drama, information on contents such as another movie or drama having a high probability of giving the user an impression or excitement is obtained. Since the information is distributed to the user terminal 2, the user can obtain information on contents such as a movie or a drama of his or her own without searching for the information.

  Furthermore, by performing statistical processing based on information indicating the degree of excitement or excitement of a plurality of users who have watched the same movie or drama in the same time zone, not only individual users but also venues or homes The degree of excitement or excitement of the viewed group can be quantified, thereby making it possible to perform an objective evaluation of a movie or a drama by eliminating the variation in evaluation among users.

Similarly, the second cloth-like device 12b is also formed by forming a comb-shaped conductive pattern 122b on one surface of the insulating cloth 121. However, the conductive patterns 112b and 122b are formed to be orthogonal to each other.

More specifically, it is possible to prevent the conductive patterns 112c and 113c from conducting erroneously and increase the durability.

[Fifth Embodiment]
FIG. 15 shows a configuration of a sensor unit 10E and a signal processing unit 20B of a body fluid detection device according to a fifth embodiment of the present invention.
On one surface of the insulating cloth body 111 of the sensor unit 10E, three conductive patterns 112d, 113d, and 114d are formed in parallel at a predetermined interval. The spacing between these conductive patterns 112d, 113d, 114d is set to, for example, 1 mm according to the amount of tears or sweat to be detected. The spacing between the conductive patterns 112d, 113d, 114d is not limited to 1 mm.

  The conductive patterns 112d, 113d, and 114d are formed on the insulating cloth 111 by bonding, printing, or weaving a conductive pattern made of conductive fibers into the insulating cloth 111. Can be used.

  On the other hand, the resistance measurement unit 21b of the signal processing unit 20B monitors the resistance between the conductive patterns for all combinations of the conductive patterns 112d, 113d, and 114d by comparing the resistances with the thresholds Th1 and Th2. . When the resistance value between certain conductive patterns falls below the threshold values Th1 and Th2, the amount of tears or sweat is determined from the combination of the conductive patterns. Then, the information indicating the determined amount of tear or sweat, the information indicating the type of the body fluid specified by which of the thresholds Th1 and Th2 is lower, and the information when the decrease in the resistance value is detected Information indicating a time or a period is included in the sensor data, and the sensor data is output to the communication unit 22. The communication unit 22 transmits the sensor data from the antenna 23 to the user terminal 2.

  With such a configuration, a user who has watched content such as a movie or a drama wipes tears or sweat with the sensor unit 10E, and as a result, as shown in FIG. It is assumed that 113d and 114d are electrically short-circuited.

  In this case, when the resistance value between the conductive patterns 113d and 114d decreases due to the attachment of the tears or the sweat 6 and falls below one of the threshold values TH1 and TH2, the resistance value measurement unit 21b sets the time or period. Generate information to represent. At the same time, the type of the body fluid is determined based on which of the threshold values TH1 and TH2 is lower, and the amount of tears or sweat is determined from the combination of the conductive patterns in which the decrease in the resistance value is detected. In the example shown in FIG. 16, it is determined that the amount of tears or sweat is small.

  As described above, according to the fifth embodiment, in the information processing server 4, information indicating the amount of sweat contained in the sensor data, the type of the body fluid, and the information indicating the generated time or period are also displayed. At the same time, it is possible to estimate in which scene of the content being watched or excited by the user, and whether the degree of the impression or excitement is large or small.

  In addition, when watching a content such as a video or a drama, if a person sheds tears due to emotion, the tears are secreted from a narrow area near the eyes. On the other hand, perspiration caused by exercise or the like is uniformly generated from a wide area of the skin. For this reason, the area of the body fluid that adheres to the sensor unit 10E differs depending on the type of the body fluid.

  Therefore, in the resistance value measuring unit 21b, for example, as shown in FIG. 18, a table defining an average attachment area in the sensor unit 10E for each type of body fluid is prepared, and the area of tears or sweat attached to the sensor unit 10E is prepared.
