[0029] As shown in FIG. 1, the biological information extraction system 100 includes a plurality of information terminals TM1, TM2, . . . , and TMn (hereinafter referred to as “information terminal TM” in the present description), a center information communication unit 106, an emotion information analysis unit 107, and an information control device 108. n is an integer of 2 or more. The information terminals TM each similarly include a position information acquisition unit 101, an image capturing unit 102, a microphone 103, a biological information extraction unit 104, a terminal information communication unit 105, a display unit 113, and a content execution application 114. The information control device 108 includes an accumulation unit 109 and an accumulation information selection unit 110. The center information communication unit 106 and the information control device 108 constitute a biological information extraction device according to the present disclosure. Each of the position information acquisition unit 101, the biological information extraction unit 104, the terminal information communication unit 105, the content execution application 114, the center information communication unit 106, the accumulation unit 109, and the accumulation information selection unit 110 is implemented by, for example, a processor such as a central processing unit (CPU), and is functionally achieved by the processor reading a program and data stored in advance in a memory (not shown). The processor may be implemented by a digital signal processor (DSP) or a field programmable gate array (FPGA).

[0030] The information terminals TM transmits and receives user information and analysis information by communicating with a center device CT, respectively. The information to be communicated is not limited to the user information and the analysis information. The information to be communicated may be content information or event information. The information terminal TM may be, for example, a smartphone or a tablet terminal, or may be implemented as a wearable microphone that can be worn by a person.

[0031] The position information acquisition unit 101 serving as an example of a processing device acquires position information of a user. A method for acquiring the position information of a user is a known technique disclosed in, for example, WO2019/187824A1, and therefore description thereof will be omitted.

[0032] The biological information extraction unit 104 serving as an example of the processing device extracts biological information of a user. Specifically, the biological information extraction unit 104 extracts heartbeat of a user based on video acquired by the image capturing unit 102. In addition, the biological information extraction unit 104 extracts vocal cord information based on voice of a user acquired by the microphone 103. Further, when the information terminal TM is a wearable terminal, the biological information extraction unit 104 may extract body temperature of a user and a perspiration state of a user. A method for extracting detailed biological information is, for example, a known technique disclosed in JP2017-153773A, and therefore description thereof will be omitted.

[0033] The terminal information communication unit 105 serving as an example of a processing device is an interface that transmits the position information of the user acquired from the position information acquisition unit 101 and the biological information of the user acquired from the biological information extraction unit 104 to the center device CT via network NW.

[0034] The center information communication unit 106 constituting the biological information extraction device and serving as an example of the processing device is an interface that receives the position information of the user and the biological information of the user which are transmitted by the terminal information communication unit 105 via the network NW.

[0035] The information control device 108 constituting the biological information extraction device and serving as an example of the processing device associates the position information of the user with the biological information of the user on based on the position information of the user and the biological information of the user received by the center information communication unit 106 (that is, association).

[0036] The accumulation unit 109 constituting the biological information extraction device and serving as an example of the processing device accumulates the number of users having the same value of the biological information for each position (specifically, for each position information) of the users based on the position information of each user and the biological information of each user. A range of the accumulated user position is not limited to the above, and may be determined for each facility or may be set by a user freely.

[0037] The accumulation information selection unit 110 constituting the biological information extraction device and serving as an example of the processing device selects biological information corresponding to a largest accumulation number of users for each position, based on the biological information indicating the same value for each user position accumulated by the accumulation unit 109. Note that information to be selected is not limited to the above, and a user may set a selection condition freely.

[0038] An event information evaluation device according to the present disclosure includes at least the center information communication unit 106, the information control device 108, and an event information providing unit 115. In addition, an event information evaluation system according to the present disclosure includes at least the plurality of information terminals TM and the information control device 108.

[0039] Next, an operation of associating the position information of the user with the biological information of the user in the biological information extraction system 100 of the first embodiment will be described with reference to FIG. 2.

[0040] In FIG. 2, the biological information extraction system 100 is started by a user executing the content execution application 114 in the information terminal TM (S1). The content execution application 114 is an application for executing (for example, playing or displaying) a content, and is provided from the event information providing unit 115 of the center device CT to the information terminal TM via the network NW. When the content execution application 114 is executed by the operation of the user, the position information acquisition unit 101 acquires current position information of the user (S2). In parallel with the acquisition of the position information of the user by the position information acquisition unit 101, the biological information extraction unit 104 acquires the video of the user from the image capturing unit 102, and acquires the voice of the user from the microphone 103. The biological information extraction unit 104 extracts biological information from the acquired video of the user and the voice of the user so as to acquire the biological information (S3). The terminal information communication unit 105 acquires the position information of the user and the biological information of the user from the biological information extraction unit 104. In addition, the terminal information communication unit 105 transmits the position information of the user and the biological information of the user to the center device CT via the network NW (S4).

[0041] The center information communication unit 106 receives the position information of the user and the biological information of the user via the network NW (S5). In the information control device 108 or the accumulation information selection unit 110, the position information of the user and the biological information of the user are associated with each other. The accumulation unit 109 aggregates position information of users and biological information of the users, and accumulates the number of users having the same value of the biological information for each position (S6). The accumulation information selection unit 110 selects biological information corresponding to the largest accumulation number of users for each position with respect to the biological information of the users for each position accumulated by the accumulation unit 109, and sets the selected biological information as biological information representing the position (S7). A display data control unit 111 creates display data in which the position information of the user, the accumulation information, and the biological information of the majority of users at the position transmitted from the information control device 108 are superimposed on a map read from map information 112 (S8). The display unit 113 of the information terminal TM receives the display data generated by the display data control unit 111 via the network NW and displays the generated display data (S9).

[0042] Next, an information control method in the information control device 108 will be described using a specific example with reference to FIGS. 3, 4, 5, 6, and 7.

[0043] In the specific example, positions to be evaluated are four positions including position 1, position 2, position 3, and position 4. Each of a, b, and c indicates, for example, the type of biological information such as the pulse rate, the tone of voice, and the body temperature. In addition, a, b, and c may indicate numerical values for the same type of biological information, respectively. In this case, for example, a, b, and c indicate body temperature 36° C., 37° C., and 38° C., respectively. The biological information is classified based on the biological information, and symbolized biological information symbols are represented by O, Δ, and X. For example, the body temperature is classified as O for 36.0° C. to 36.9° C., Δ for 37.0° C. to 37.9° C., and X for 38.0° C. to 38.9° C.

[0044] When the position information of the user and the biological information of the user are acquired from the center information communication unit 106, the accumulation unit 109 associates the position information of the user with the biological information of the user, and creates a table shown in FIG. 3. The accumulation unit 109 accumulates the number of users having the biological information of the same value (for example, biological information or biological information symbol, or both of them) at each position based on the table shown in FIG. 3, and creates a table shown in FIG. 4. The accumulation information selection unit 110 selects biological information corresponding to the largest accumulation number of users for each position based on the table shown in FIG. 4. In other words, the accumulation information selection unit 110 selects biological information whose rank is “1” for each position in FIG. 4. The accumulation information selection unit 110 generates a table shown in FIG. 5 based on the selected biological information.

[0045] The display data control unit 111 creates display data based on the tables shown in FIGS. 3 and 5 acquired from the information control device 108 and the map information 112 stored in advance. For example, FIG. 6 is display data generated by the display data control unit 111 based on the table of FIG. 3 and the map information. In the display data shown in FIG. 6, the position of each user and the biological information of each user are displayed. By generating the display data shown in FIG. 6, a user and a content provider can visually recognize a gathering state of the users and the biological information of the users on the map at the information terminal TM and the center device CT. The display data shown in FIG. 7 indicates the biological information of the majority of users at the position for each position. By generating the display data shown in FIG. 7, the user and the content provider can visually recognize the biological information for each position on the map at the information terminal TM and the center device CT. As a result, by generating the display data of FIGS. 6 and 7, the user and the content provider can easily evaluate the provided content.

[0046] Note that this specific example is merely an example, and the configuration is not limited thereto. For example, the biological information selected in FIG. 5 may be selected from any rank in FIG. 4. The event information sent from the event information providing unit 115 is not limited to the content information. For example, the information may be disaster information or event information.

Second Embodiment

[0047] A second embodiment is a form in which the biological information in the first embodiment is further analyzed by an emotion information analyzing unit 107 to be described later to select the emotion information of the user.

[0048] The second embodiment will be described with reference to FIG. 8. FIG. 8 is a detailed configuration diagram of the biological information extraction system 100 according to the second embodiment. FIG. 9 is a diagram showing an operation flow of the biological information extraction system 100 according to the second embodiment. FIG. 10 is a diagram showing an example of a table in which position information of users and emotion information of the users are aggregated in the biological information extraction system 100 according to the second embodiment. FIG. 11 is a diagram showing an example of a table in which emotion information of users at each position is accumulated in the biological information extraction system 100 according to the second embodiment. FIG. 12 is a diagram showing an example of a table in which emotion information having a largest accumulation number of users is selected for each position in the biological information extraction system according to the second embodiment. FIG. 13 is a diagram showing display data generated based on the position information of the users, the emotion information of the users, and map information in the biological information extraction system according to the second embodiment. FIG. 14 is a diagram showing display data generated based on the map information and the emotion information having the largest accumulation number of users for each position in the biological information extraction system according to the second embodiment. A difference between the second embodiment and the first embodiment is whether the emotion information analyzing unit 107 is provided. The same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be simplified or omitted, and different contents will be described.

[0049] The biological information extraction system 100 according to the second embodiment includes the emotion information analyzing unit 107 in addition to the configuration of the biological information extraction system according to the first embodiment. The emotion information analyzing unit 107 is a part of the biological information extraction device.

[0050] The emotion information analyzing unit 107 constituting the biological information extraction device and serving as an example of the processing device analyzes the biological information of the users received by the center information communication unit 106, and estimates emotion information of the user based on an analysis result. A detailed emotion information estimating method is, for example, a known technique disclosed in JP2019-040525A, and therefore description thereof will be omitted.

[0051] Next, an operation of associating the position information of the user with the emotion information of the user in the biological information extraction system 100 of the second embodiment will be described with reference to FIG. 9.

[0052] In FIG. 9, the biological information extraction system 100 is started by executing the content execution application 114 by operation on the information terminal TM of the user (S91). The content execution application 114 is provided from the event information providing unit 115 of the center device CT to the information terminal TM via the network NW. When the content execution application 114 is executed by the operation of the user, the position information acquisition unit 101 acquires current position information of the user (S92). In parallel with the acquisition of the position information of the user by the position information acquisition unit 101, the biological information extraction unit 104 acquires the video of the user from the image capturing unit 102, and acquires the voice of the user from the microphone 103. The biological information extraction unit 104 extracts biological information from the acquired video of the user and the voice of the user so as to acquire the biological information (S93). The terminal information communication unit 105 acquires the position information of the user and the biological information of the user from the biological information extraction unit 104. In addition, the terminal information communication unit 105 transmits the position information of the user and the biological information of the user to the center device CT via the network NW (S94).

[0053] The center information communication unit 106 receives the position information of the user and the biological information of the user via the network NW (S95). The emotion information analyzing unit 107 acquires the biological information of the user received by the center information communication unit 106, and analyzes the biological information of the user. The emotion information analyzing unit 107 estimates the emotion information of the user based on an analysis result of the biological information of the user (S96). In the information control device 108 (for example, the accumulation information selection unit 110), the position information of the user and the emotion information of the user are associated with each other. The accumulation unit 109 aggregates position information of users and emotion information of the users, and accumulates the number of users having the same value of the emotion information for each position (S97). The accumulation information selection unit 110 selects emotion information having the largest accumulation number of users for each position with respect to the emotion information of the user for each position accumulated by the accumulation unit 109, and sets the selected emotion information as emotion information of the majority of users at the position (S98). The display data control unit 111 generates display data based on the position information of the user, the accumulation information, the emotion information of the majority of users at the position which are transmitted from the information control device 108, and the map information 112 (S99). The display unit 113 receives the display data generated by the display data control unit 111 via the network NW and displays the generated display data (S100).

[0054] Next, an information control method in the information control device 108 will be described using a specific example with reference to FIGS. 10, 11, 12, 13, and 14.

[0055] In the specific example, positions to be evaluated are four positions including position 1, position 2, position 3, and position 4. There are three types of emotional information a, b, and c to be evaluated. Each of a, b, and c indicates a type of emotional information such as a concentration degree and delight, anger, sorrow and pleasure. In addition, numerical values may be as indication for the same type of emotion information. In this case, for example, a, b, and c indicate concentration degrees 10, 50, and 100, respectively. The emotion information is classified based on the emotion information, and symbolized emotion information symbols are represented by O, Δ, and X. For example, the body temperature is classified as O for 36.0° C. to 36.9° C., Δ for 37.0° C. to 37.9° C., and X for 38.0° C. to 38.9° C.

[0056] The accumulation unit 109 acquires the position information of the user from the center information communication unit 106, and acquires the biological information of the user from the emotion information analyzing unit 107. The accumulation unit 109 associates the position information of the user with the emotion information of the user, so as to create a table shown in FIG. 10. The accumulation unit 109 accumulates the number of users for each emotion information at each position based on the table shown in FIG. 10, and creates a table shown in FIG. 11. The accumulation information selection unit 110 selects biological information corresponding to the largest accumulation number of users for each position based on the table shown in FIG. 11. In other words, the accumulation information selection unit 110 selects emotion information whose rank is “1” for each position in FIG. 11. The accumulation information selection unit 110 generates a table shown in FIG. 12 based on the selected emotion information.

[0057] The display data control unit 111 creates display data based on the tables shown in FIGS. 10 and 12 acquired from the information control device 108 and the map information 112 stored in advance. For example, FIG. 13 is display data generated by the display data control unit 111 based on the table of FIG. 10 and the map information. In the display data shown in FIG. 13, the position of each user and the emotion information of each user are displayed. By generating the display data shown in FIG. 13, a user and a content provider can visually recognize a gathering state of the users and the emotion information of the users on the map at the information terminal TM and the center device CT. The display data shown in FIG. 14 indicates emotion information of the majority of users at the position for each position. By generating the display data shown in FIG. 14, the user and the content provider can visually recognize the emotion information for each position on the map at the information terminal TM and the center device CT. As a result, by generating the display data of FIGS. 13 and 14, the user and the content provider can easily evaluate the provided content.

[0058] Note that this specific example is merely an example, and the configuration is not limited thereto. For example, the biological information selected in FIG. 12 may be selected from any rank in FIG. 11. The event information sent from the event information providing unit 115 is not limited to the content information. For example, the information may be disaster information or event information.
