(Prerequisite technology)

  In recent years, devices for measuring biological information such as a person's heartbeat, pulse, blood pressure, and the like have become widespread. Moreover, the technique which estimates the mental state of a person by analyzing these biometric information is reported.

  For example, the paper “Hopeless Is Associated With Decreased Heart Rate Variability During Championship Chess Games” (http://www.psychosomaticmedicine.org/content/65/4/658.) By Alfons M. Schwarz et al. short (searched on September 10, 2011) reports an attempt to measure a time change of a player's heartbeat while playing a chess and recognize a change in the psychology of the player.

FIG. 1 is a diagram illustrating an example of an electrocardiogram representing a time change of a person's heartbeat. In the electrocardiogram shown in FIG. 1, the interval between peaks is called the RR interval. In FIG. 1, three RR intervals, RR ₁ , RR ₂ , and RR ₃ are illustrated.

  In the above-mentioned paper, a study of analyzing a RR interval to identify a human emotion is reported. Specifically, the time change of the player's heart rate while playing chess is measured, and the change of the player's psychological state is recognized by analyzing HF (High Frequency) of HRV (Heart Rate Variability). It is an attempt to try. Here, HRV is an index representing a change in the RR interval. According to the above-mentioned paper, when HF of HRV (HF-HRV) increases, it is shown that it is optimistic or positive mood, and conversely, when HF-HRV decreases, it is pessimistic or backward mood. It has been reported that.

  In general, HF-HRV is known to exhibit high values when relaxed. On the other hand, it is known that the low frequency region (LF-HRV) of HRV shows a high value in the case of a tension state, and the strength of HF-HRV also decreases. In this way, a technique for reading a person's mood by detecting a temporal change in biological information is being reported by universities and research institutions.

  As a device for measuring the RR interval, a medical Holter electrocardiograph and a heart rate monitor as a training device have been put into practical use. By always wearing a heart rate meter capable of measuring the RR interval, it is possible to measure the time change of the wearer's heart rate.

  FIG. 2 is a diagram illustrating an example of a person's heartbeat and an analysis result thereof. FIG. 2A is a diagram illustrating a graph representing a temporal change in a person's heart rate. FIG. 2B is a spectrogram showing a spectral distribution of 0 to 0.5 [Hz] in the graph shown in FIG. FIG.2 (c) is a figure which shows the graph which integrated the spectral intensity in the frequency of 0.15-0.4 [Hz]. This frequency region corresponds to HF (high frequency region) of HRV. And FIG.2 (d) is a figure which shows the graph showing the moving average of the graph shown in FIG.2 (c). Here, the size of the window when calculating the moving average is 128 [seconds]. The higher the value on the vertical axis of the graph shown in FIG. Conversely, the lower the value on the vertical axis of the graph shown in FIG. The latter case includes a case where each item is concentrated, and does not necessarily indicate a negative mental state. However, when considering restaurants and entertainment facilities, it is not preferable that the customer is in tension.

In the example shown in FIG. 2, the average value and standard deviation of HF-HRV during the activity of the subject are 2.9 [sec ² ] and 1.2 [sec ² ], respectively. However, FIG. 2 is a graph obtained by measuring 30 minutes at a certain time. From FIG. 2, it is not possible to calculate data on the subject's daily activity. In the above-mentioned paper, the psychological state of the subject is defined as “optimistic” when HF-HRV increases by 1 standard deviation or more from the average of HF-HRV, and “unoptimistic” when it decreases by 1 standard deviation or more. ing.

Following this definition, looking at Figure 2 (d), the first 1200 seconds (20 minutes) continues to be 1.2 [sec ² ] higher than the average of 2.8 [sec ² ], It can be determined that the subject's psychological state is “optimistic”. From 1200 seconds to 1600 seconds, a decrease in the HF component is observed. In this 400 seconds (about 6 minutes), HF-HRV is near the average value of the subjects, and is not “unintentional”, but is considered to be just ridiculous. As described above, there is a technique for estimating a person's psychological state by analyzing temporal variation of the person's biological information.

An embodiment of the present invention will be described based on the above technique.
(Embodiment)

  An outline of the embodiment will be described. The information disclosure system 100 according to the embodiment estimates the user's psychological state by analyzing the temporal variation of the biological information of the user who uses a certain store, and estimates the satisfaction of the user. The information disclosure system 100 associates user satisfaction with store location information and publishes it as map-format information on the network.

  For convenience of explanation, heart rate information will be described as a main example as biological information. The embodiment of the present invention can be established even when biological information other than heartbeat information is used. However, since there is an existing device that measures heart rate information, research on the relationship between heart rate information and psychological state is progressing, and heart rate information is also useful for user health management. There are advantages to adopting.

  Since the embodiments described below are preferable specific examples of the present invention, various technically preferable limitations are attached thereto. However, the scope of the present invention is particularly limited in the following description. Unless otherwise described, the present invention is not limited to these forms.

  FIG. 3 is a diagram showing an overview of the information disclosure system 100 according to the embodiment. FIG. 3 shows two users 500a and 500b. Users 500a and 500b have client devices 200a and 200b, respectively. Hereinafter, the user is generically referred to as “user 500”, and the client apparatus is generically referred to as “client apparatus 200”.

  The information disclosure system 100 includes a client device 200 and a server 300. The client device 200 and the server 300 are connected via a network 400 such as the Internet or a mobile phone line, and can communicate with each other. Further, the client device 200 can acquire position information from, for example, a GPS (Global Positioning System) satellite 600 or the like. When the user 500 possesses the client device 200 and uses the store, the client device 200 can acquire the position information of the client device 200 from the GPS satellite 600, that is, the position information indicating the location of the user 500. For example, when the user 500 is in a store such as a cafe or a bar, the store can be specified from the position information of the user 500.

  FIG. 4 is a diagram illustrating a state of wearing the biological information acquisition unit 220 according to the embodiment. In the example illustrated in FIG. 4, the biological information acquisition unit 220 is a heartbeat measuring device and is directly attached to the body of the user 500. The biometric information acquisition unit 220 and the client device 200 are connected using a low power consumption data communication technology such as Bluetooth (registered trademark). The client device 200 is connected to the network 400 via a mobile phone line. In the example shown in FIG. 4, the base station of the mobile phone line is a part of the network 400.

  FIG. 5 is a diagram schematically illustrating a functional configuration of the information disclosure system 100 according to the embodiment. As described above, the information disclosure system 100 includes the client device 200 and the server 300. A plurality of client devices 200 are connected to the server 300 via a network. Further, a terminal device 202 for browsing map information provided by an information providing unit 360 in the server 300 described later is connected to the server 300. The terminal device 202 is a general PC (Personal Computer), for example, and does not include the biological information acquisition unit 220.

  The client device 200 includes a position information acquisition unit 210, a biological information acquisition unit 220, a biological information storage unit 230, an input / output unit 240, and a client control unit 250.

  The biometric information acquisition unit 220 acquires time variation of the biometric information of the user who uses the client device 200. The biometric information acquisition unit 220 acquires an HRV signal transmitted using a low power consumption data communication technique from, for example, a heart rate measurement device, a Holter electrocardiograph, or an electrocardiograph using a chest band attached to the body of the user 500. . Alternatively, for example, when measuring the amount of sweat of the user's hand as biometric information, the biometric information acquisition unit 220 is directly incorporated into the client apparatus 200 as a humidity measurement device. As described above, the device for measuring the biological information may be directly incorporated into the client apparatus 200 depending on the biological information to be measured, or may be a different device from the client apparatus 200. It is included in the embodiment.

  The biometric information storage unit 230 includes the user 500 using the client device 200, the fluctuation of the heartbeat of the user acquired by the biometric information acquisition unit 220, and the measurement time of the heartbeat acquired from a timer (not shown) in the client device 200. Are stored in association with each other. The biometric information storage unit 230 also stores statistics such as the average value and standard deviation of HF-HRV when the user 500 is active.

  The position information acquisition unit 210 acquires the presence position of the client device 200. This can be realized by receiving a GPS signal transmitted from the GPS satellite 600, for example. The input / output unit 240 is a user interface for the user 500 who uses the client device 200, and is realized by, for example, a touch panel. The input / output unit 240 functions as a display device that displays information acquired from the server 300 via the network 400, and also functions as an input device for the user 500 to create character information such as comments.

  The client control unit 250 comprehensively controls each unit in the client device 200 described above. The client control unit 250 transmits the HRV information measured by the biological information acquisition unit 220 to the server 300 via the network 400 together with the location information of the user 500. The client control unit 250 can be realized by, for example, an OS (Operating System) of the client device 200 and a CPU (Central Processing Unit) that executes the OS.

  The server 300 includes a psychological state analysis unit 310, a store identification unit 320, a store database 330, a comment acquisition unit 340, a store evaluation storage unit 350, an information provision unit 360, and a server control unit 370 that comprehensively controls them.

  The psychological state analysis unit 310 analyzes the psychological state of the user 500 who uses the client device 200 based on the temporal variation of the biological information acquired from the client device 200 via the network 400. Specifically, the psychological state analysis unit 310 analyzes the psychological state of the user 500 based on the above-described prerequisite technology.

  The store database 330 stores commercial facilities and stores such as cafes, restaurants, and amusement parks, and location information such as longitude, latitude, and altitude of locations where these stores exist. The store identifying unit 320 identifies the store where the user is located by referring to the store database 330 based on the position information sent from the client device 200 along with the time variation of the biological information. Thus, by simultaneously analyzing the psychological state of the user 500 and the positional information of the user 500, it becomes possible to grasp the psychological state of the user 500 who is a customer in a store in a certain area.

  The comment acquisition unit 340 acquires a comment of the user 500 created by the input / output unit 240 in the client device 200 and transmitted via the network 400. The store evaluation storage unit 350 stores the psychological state of the user 500 analyzed by the psychological state analysis unit 310, the store specified by the store specifying unit 320, and the comment of the user 500 acquired by the comment acquisition unit 340.

  The information providing unit 360 refers to the store evaluation storage unit 350 and publishes the psychological state of the user 500 in the store specified by the store specifying unit 320 in a manner that can be browsed via the network 400. Although details will be described later, the information providing unit 360 displays the user's psychological state analyzed by the psychological state analyzing unit 310 on a map in a manner that is different for each psychological state.

  The server 300 acquires the HRVs of the plurality of users 500 via the network 400 and analyzes the psychological states of the plurality of users 500 in a certain area and a certain store. From the psychological state of a plurality of users 500, it is possible to estimate the atmosphere in the area and store. As described above, in order to recognize the psychological state of the user, the average value and standard deviation of HF-HRV of each customer are required. For this reason, the psychological state analysis unit 310 receives, from the biometric information storage unit 230 in the plurality of client devices 200 via the network 400, statistics such as the average value and standard deviation of HF-HRV of each user who uses the client device. Is stored in a statistics storage unit (not shown).

  The psychological state analysis unit 310 includes the time variation of the heartbeat interval measured by the biometric information acquisition unit 220 in the client device 200 used by each user 500 and the biometric information storage unit 230 in the client device 200 used by each user 500. The psychological state of each user who uses the client device 200 is analyzed based on the statistic specific to each user 500 stored in. As a result, individual differences in the biometric information of each user 500 can be absorbed and the psychological state can be analyzed more accurately. If the statistics specific to each user 500 cannot be referred to, the psychological state analysis unit 310 analyzes the psychological state using representative statistics.

  FIG. 5 shows a functional configuration for realizing the information disclosure system 100, and other configurations are omitted. In FIG. 5, each element described as a functional block for performing various processes is, in terms of hardware, the CPU of the server 300 and the client device 200 constituting the information disclosure system 100, the main memory, and other LSI (Large Scale). Integration), and in terms of software, it is realized by a program or the like loaded in the main memory. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms depending on the calculation resources of the information disclosure system 100, and is not limited to any one.

  FIG. 6 is a diagram illustrating an example of a map presented by the information providing unit 360 according to the embodiment. FIG. 6 shows a map displaying commercial facilities and shops existing around the station centered on a certain “station”. On the map, a figure in which a capital letter is attached to a waiting needle-shaped pattern made up of a sharp triangle and a circle indicates the location of the store. For example, in FIG. 6, a graphic with an alphabet “G” indicates a position where an aquarium as a commercial facility exists. In addition, since the stores indicated by the alphabets “A”, “B”, and “I” are stores that exist in the vicinity of each other, they are also shown at close positions on the map. The same applies to the stores indicated by the letters “C”, “E”, and “F”. Hereinafter, the store indicated by the alphabet may be simply referred to as “store A”.

  The information providing unit 360 displays the user's psychological state of the user 500 in the store analyzed by the psychological state analyzing unit 310 on a map in a different manner for each psychological state and publishes it. The psychological state analysis unit 310 analyzes the psychological states of a plurality of users from the biological information acquired via the network 400. As a result, for example, the atmosphere of a certain area such as a shopping street can be detected macroscopically. For example, in FIG. 6, a circular area including the store A, the store B, and the store I is hatched with a downward slant. This represents that the psychological state of the user in the store in this area tends to be “pessimistic”, that is, the degree of satisfaction tends to be low. On the other hand, the circular area including the store C, the store E, and the store F is dotted with dots. This indicates that the psychological state of the user in the store in this area tends to be “optimistic”, that is, the degree of satisfaction tends to be high.

  In this way, by displaying the psychological state of the user 500 who is currently using a certain region or store on the map and making it public, the person who has browsed the information has what kind of atmosphere the region and store are currently in It becomes possible to recognize. When a person browsing the map published by the information providing unit 360 selects the store shown on the map by clicking, for example, with a mouse, detailed information such as the store address and evaluation of other users (Not shown) is displayed. The detailed information of the store includes the comment of the user 500 acquired by the comment acquisition unit 340. Alternatively, when the user 500 posts a blog, microblog, etc., the information is also displayed.

  In the above-described process of publishing the psychological state of the user who uses the store on the network 400, detection of biometric information and transfer of biometric information to the server 300 can all be automated. For this reason, it is possible to publish almost real-time information without making the user troublesome. Therefore, the person who browsed the information provided by the information providing unit 360 can also predict the atmosphere of the current store or region. This may provide new value, for example, to those who are going to visit the area or to choose a store to eat.

  The server 300 detects the psychological state of the user with respect to a specific event occurring in a certain region or store by associating the time change of the biological information of the user who uses the store with the GPS information in real time. Is possible. The information on the detected psychological state is a quantitative evaluation for the event. Also, the business operator can obtain quantitative evaluation information for the event and use it for business improvement.

  For example, when a restaurant is taken as an example of a store, it becomes possible to analyze a customer's psychological state with respect to an event such as a live music event or a tuna dismantling show being performed at the store, and quantitatively measure the effect of the event be able to. In addition, it is possible to select an optimum BGM for the store by playing a BGM (Back Ground Music) to be verified at a specific time and analyzing a customer's psychological state with respect to the BGM. In addition, for course meals such as wedding receptions, where meals are provided in advance, it is possible to analyze changes in the customer's psychological state for each dish and select the optimal combination of course meals. It becomes possible. In addition, the present invention can be applied to an event performed at any place performed in association with time.

  For example, when a user having the client device 200 is in an environment where the user cannot connect to the network 400, the information stored in the biometric information storage unit 230 may be transmitted to the server 300 when communication becomes possible later. Good. Although it is preferable to automatically transmit such information, it may be transmitted by a user operation.

  FIG. 7 is a flowchart showing a process flow of the information disclosure system 100 according to the embodiment. The processing in this flowchart starts when the user 500 carries the client device 200, for example.

  The biometric information acquisition unit 220 measures the temporal variation of the biometric information of the user 500 who uses the client device 200 (S2). The position information acquisition unit 210 acquires a GPS signal from the GPS satellite 600 and acquires the current position information of the client device 200 (S4).

  The psychological state analysis unit 310 analyzes the psychological state of the user 500 based on the temporal variation of the biometric information of the user 500 acquired by the biometric information acquisition unit 220 (S6). The store specifying unit 320 specifies a store currently used by the user 500 using the client device 200 based on the GPS information acquired by the position information acquiring unit 210 (S8).

  The comment acquisition unit 340 acquires a comment posted by the user via the input / output unit 240 (S10). The store evaluation storage unit 350 stores the store currently used by the user 500, the psychological state of the user 500, and the comment posted by the user 500 in association with each other (S12). The information providing unit 360 publishes the information stored in the store evaluation storage unit 350 in a form that can be browsed by other users 500 via the network (S14). When the information providing unit 360 discloses the information, the processing in this flowchart ends.

  The operation according to the above configuration is as follows. When the user 500 possesses the biometric information acquisition unit 220 and the client device 200 and uses a store, the biometric information acquisition unit 220 measures the time variation of the biometric information of the user 500, and the position information acquisition unit 210 acquires GPS information. . These pieces of information are transmitted to the server 300 via the network 400, and the psychological state analysis unit 310 analyzes the psychological state of the user 500 based on the biological information. The store specifying unit 320 specifies the store currently used by the user 500 from the GPS information.

  The information providing unit 360 associates the store currently used by the user 500 with the psychological state of the user 500 and publishes it in a form that can be browsed by other users 500 via the network 400.

  As described above, according to the information disclosure system 100 according to the embodiment of the present invention, it is possible to provide a technique that enables a store to be evaluated based on an objective evaluation criterion.

  Moreover, since the information used for evaluation can be automatically sent to the server 300 that performs analysis via the network 400, it is possible to reduce the labor of the evaluator such as a store. The psychological state analysis unit 310 in the present embodiment analyzes the user's psychological state based on the temporal variation of the biological information of the user 500. The time variation of the biological information of the user 500 is information having a time axis that changes with time. Therefore, the psychological state analysis unit 310 can analyze the temporal change of the psychological state of the user 500. The time change information of the psychological state is advantageous in that the user 500 using a certain store has a lot of information in the time axis direction as compared with the evaluation performed comprehensively after using the store.

  By the way, the position information acquisition unit 210 and the biological information acquisition unit 220 described above belong to each client device 200. If these belong to the server 300, it is meaningless because the biological information of the user 500 cannot be measured and the position information of the user 500 cannot be acquired. It is appropriate that the client control unit 250 and the input / output unit 240 also belong to the client device 200.

  It is preferable that the store evaluation storage unit 350 that stores information associated with many users 500 and the store database 330 that stores a large amount of store information belong to the dedicated server 300. In addition, it is preferable that the comment acquisition unit 340 that acquires comments created by many users 500 and the information provision unit 360 that refers to the store evaluation storage unit 350 also belong to the server 300.

  On the other hand, the psychological state analysis unit 310, the store identification unit 320, and the biometric information storage unit 230 may be established as an embodiment of the present invention regardless of whether they belong to the client device 200 or the server 300. . For example, when the psychological state analysis unit 310 is in the client device 200, the psychological state is analyzed using the CPU of the client device 200 and the result may be transmitted to the server 300. When the store specifying unit 320 is in the client device 200, the store specifying unit 320 may access the store database 330 in the server 300 via the network 400 and specify the store.

  Thus, in the information disclosure system 100, the configuration of each unit and the subject of processing have a degree of freedom. The description of all cases is complicated and complicated, and will be omitted because the point of the present invention becomes unclear. However, those skilled in the art will understand that both cases are included in this embodiment. is there.

The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .
(Modification 1)

  In the above description, the case where the psychological state analysis unit 310 analyzes the psychological state based on the average value or standard deviation of the RR interval that varies with time has been described. Here, the psychological state analysis unit 310 may change the analysis method according to the life pattern and activity status of each user 500.

  The biological information storage unit 230 stores the biological information of the user 500 along with the time. For example, if the average value of a certain user's RR interval varies with time, the psychological state analysis unit 310 changes the average value of the RR interval and the standard deviation of the RR interval used for analysis of the psychological state according to the time. Thereby, the analysis accuracy of the psychological state of the user 500 can be improved.

In general, the RR interval at rest tends to be longer than the RR interval at exercise. Therefore, the psychological state analysis unit 310 may change the analysis method by estimating whether the user 500 is resting or active from the time change of the position information acquired by the position information acquisition unit 210. For example, the psychological state analysis unit 310 may analyze the psychological state when it is recognized that the user 500 is at rest. Alternatively, when it is recognized that the user 500 is active, the psychological state analysis unit 310 may change various signal processing and filters used for the analysis of the psychological state, such as the above-described filter for calculating the moving average. Good. Thereby, the activity status of the user 500 can be reflected in the analysis of the psychological state, and the analysis accuracy can be improved.
(Modification 2)

  For example, when the user 500 cannot receive a signal directly from a GPS satellite such as when the user 500 is in the back of the store, a “GPS signal re-radiation system” may be installed in the store. The GAS signal re-radiation system is a mechanism in which a GPS information receiving antenna is installed on the roof of a building and the GPS signal is re-radiated in the building. If this system is used, altitude information of the GPS signal is not correct, but two-dimensional information of latitude and longitude can be obtained, and the position of the user 500 can be displayed on the map.
