Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the information processing system and the information processing method according to the present disclosure will be described in detail with reference to the drawings. Note that each of the embodiments described below shows a preferred specific example of the present disclosure. Therefore, numerical values, shapes, materials, components, arrangements and connection forms of the components shown in the following embodiments are examples, and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, components not described in the independent claims are described as optional components.

[0011] It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Also, in each figure, the same reference numerals are given to substantially the same configurations, and duplicate explanations may be omitted or simplified.

[0013] [Embodiment] (Information Processing System) The information processing system according to the embodiment has a function of notifying the user of the planned usage quantity of various types of sanitary products that can be used by the user. Here, examples of sanitary products include napkins, tampons, absorbent shorts, menstrual cups, menstrual discs, and kotex sheets. In the present embodiment, a napkin is exemplified as the sanitary product.

[0014] FIG. 1 is a block diagram showing the configuration of an information processing system 10 according to the embodiment. As shown in FIG. 1, the information processing system 10 includes a measurement device 100, an information notification device 200, and a server device 300.

[0015] The measurement device 100 is a trash can-type device in which a napkin is discarded. FIG. 2 is a perspective view showing the appearance of the measurement device 100 according to the embodiment. FIG. 3 is a schematic diagram showing the internal structure of the measurement device 100 according to the embodiment.

[0016] As shown in FIGS. 2 and 3, the measurement device 100 is formed in a rectangular parallelepiped shape as a whole and has a main body portion 110 and a lid portion 120. The main body portion 110 is a rectangular box-shaped portion with an open upper part. The lid portion 120 is rotatably supported at the upper end portion of the main body portion 110 and is adapted to open and close the open portion of the main body portion 110. The base end portion of the lid portion 120 is connected to a drive portion 130 via a mechanism portion 131. The drive portion 130 is, for example, a motor. The lid portion 120 is rotationally driven by the mechanism portion 131 that operates when the drive portion 130 is driven. That is, the lid portion 120 automatically opens and closes.

[0017] In the main body 110, on the wall portion (front wall) on the open end side of the lid portion 120, an optical sensor 140, a light emitting portion 150, and a reading portion 165 are arranged on the upper front surface thereof. The optical sensor 140 is, for example, an infrared sensor. The light emitting portion 150 is, for example, an LED, which lights up when the power is turned on and goes out when the power is turned off. The reading portion 165 is, for example, a card reader, which reads the ID card of the user or the ID information of the information notification device 200. The reading portion 165 may be a barcode reader or an NFC (Near Field Communication) compatible device. In the present embodiment, the case where the ID information is acquired by reading with the reading portion 165 of the measuring device 100 is illustrated, but the acquisition of the ID information is not limited thereto. For example, a reading device may be installed at the entrance and exit of the toilet, and the user may be made to read the ID information of the ID card with the reading device when entering the room, thereby acquiring the ID information. In this case, the reading device is a part of the information processing system 10. It is also possible to adopt a biometric authentication device that reads the biometric information (fingerprint, face, iris, etc.) of the user as the reading portion. In this case, the ID information of each user and the biometric information are associated and registered in advance, and by collating the biometric information read by the biometric authentication device, the ID information associated with the biometric information can be acquired.

[0018] A garbage bag is set inside the main body 110. For this reason, a fixing portion 111 for fixing the garbage bag is provided on the front wall of the main body 110. At the bottom inside the main body 110, a weight sensor 160 for measuring the weight of the garbage bag and the articles (mainly used napkins) stored therein is arranged. The weight sensor 160 is, for example, a load cell.

[0019] Inside the main body 110, at the bottom, the communication unit 170 and the control unit 180 are provided in a state of being mounted on the same substrate. The communication unit 170 is a communication module that performs wired and / or wireless communication. The control unit 180 includes a CPU, a ROM, and a RAM, and the CPU expands and executes the program in the ROM in the RAM to control each part of the measuring device 100. Specifically, the control unit 180 controls the drive unit 130, the optical sensor 140, the light emitting unit 150, the weight sensor 160, the reading unit 165, and the communication unit 170.

[0020] Inside the main body 110, a power supply unit 190 that supplies power to the drive unit 130, the optical sensor 140, the light emitting unit 150, the weight sensor 160, the reading unit 165, the communication unit 170, and the control unit 180 is provided. The power supply unit 190 may be a rechargeable battery or a power supply device connected to an external power supply via a power outlet. When the power supply unit 190 is a rechargeable battery, it is preferable to arrange the power supply unit 190 inside the side surface of the main body 110. Thereby, it becomes possible to replace the power supply unit 190 without lifting the main body 110. Therefore, it is possible to suppress a decrease in the accuracy of the weight sensor 160 caused by lifting. If lifting is unnecessary, the frequency with which the user touches the main body 110 in the toilet can be reduced, and the sense of uncleanliness felt by the user can be suppressed.

[0021] As shown in FIG. 1, the information notification device 200 is a terminal device that can communicate with the measurement device 100 and the server device 300. The information notification device 200 includes a touch panel unit 210, a sound output unit 220, a sound input unit 230, a storage unit 240, an imaging unit 250, a communication unit 260, and a control unit 270. The touch panel unit 210 is a touch panel having a liquid crystal or an organic EL panel. The sound output unit 220 is a speaker. The sound input unit 230 is a microphone. The storage unit 240 is a storage device such as a hard disk drive or an SSD (Solid State Drive). The imaging unit 250 is a camera. The communication unit 260 is a wired and / or wireless communication module. The control unit 270 includes a CPU, a ROM, and a RAM, and the CPU expands and executes a program in the ROM in the RAM to control each part of the information notification device 200.

[0022] Examples of the information notification device 200 include smartphones, tablet terminals, wearable terminals (such as smartwatches and smart glasses), notebook PCs, portable game machines, and the like. The information notification device 200 may be any terminal device that can execute a search in the server device 300 by acquiring search information. Examples of the search information include keywords input to the touch panel unit 210. In the case of the information notification device 200 capable of voice recognition, keywords based on the voice input to the sound input unit 230 may be used as the search information. The search information also includes barcodes (including two-dimensional barcodes) photographed by the imaging unit 250. Further, the image itself photographed by the imaging unit 250 is also included in the search information.

[0023] The server device 300 is a server device that can communicate with the measurement device 100 and the information notification device 200. For example, the server device 300 can communicate with the measurement device 100 and the information notification device 200 via the Internet or a local area network. The server device 300 is a database that associates the types of sanitary products with the weights of various sanitary products before use and stores them. In the present embodiment, the server device 300 is exemplified as an example of the database, but the storage unit 240 of the information notification device 200 may store the database.

[0024] In the server device 300, the database is edited by an administrator. Also, the server device 300 may be accessible to terminals provided in a napkin manufacturer. In this case, the napkin manufacturer can access the server device 300 to edit the database. The server device 300 may set access rights different from those of general users for the napkin manufacturer, or may set a login method different from that of general users. The database may be a shared database for multiple people or a personal database.

[0025] FIG. 4 is an explanatory diagram showing an example of a database according to the embodiment. As shown in FIG. 4, in the database of the server device 300, identification information, company name, brand name, size, classification, features, weight, absorption amount, JAN code, etc. are associated and stored for each type of napkin. Here, the identification information is information set for each type of napkin. The size indicates the length of the napkin in the longitudinal direction. The classification indicates whether it is a daytime napkin, a nighttime napkin, or a napkin for going out. The features indicate whether it is a napkin with wings or a napkin without wings. The weight indicates the weight of the napkin before use. The absorption amount is the amount of menstrual blood that the napkin can absorb. The JAN code is the product identification number of the napkin. Although not shown here, the thickness of each napkin may also be stored in the database.

[0026] The editing of the database may be editing performed through a WEB browser or by uploading a file in a specific database format such as a CSV file. Examples of the order for display in the database include alphabetical order, registration order, recommended order, share order, etc. The recommended order is the order recommended by the manufacturer to the user. Thereby, for example, new products can be displayed at the top, and it becomes possible to enhance the PR effect.

[0027] For example, when a keyword search is performed by the information notification device 200, the types of napkins associated with the keyword are searched in the database of the server device 300. Further, when the information notification device 200 captures and reads a barcode (including a two-dimensional barcode), the types of napkins associated with the JAN code indicated by the read barcode are searched in the database of the server device 300.

[0028] (Information processing method) Next, an information processing method executed by the information processing system 10 according to the embodiment will be described. The information processing method includes a measuring device processing method executed by the measuring device 100 and an information notification device processing method executed by the information notification device 200.

[0029] First, the measuring device processing method will be described. FIG. 5 is a flowchart showing the measurement processing method according to the embodiment. As shown in FIG. 5, in step S101, the control unit 180 of the measuring device 100 determines whether or not it has acquired a detection signal from the optical sensor 140.

[0030] FIG. 6 is an explanatory diagram showing the detection range R10 of the optical sensor 140 according to the embodiment. As shown in FIG. 6, the optical sensor 140 is disposed at a position not covered by the open end of the lid portion 120. When a detection target H such as a user's hand enters the detection range R10 of the optical sensor 140, the optical sensor 140 outputs a detection signal to the control unit 180.

[0031] As shown in FIG. 5, in step S101, when the control unit 180 has acquired a detection signal from the optical sensor 140, it proceeds to step S102, and when it has not acquired the detection signal, it proceeds to step S110.

[0032] In step S102, the control unit 180 performs zero correction processing on the weight sensor 160. The zero correction processing is a process of correcting the strain detected by the load cell, which is the weight sensor 160, and the voltage value at that time to zero. At this time, whether the inside of the measuring device 100 is empty or there is dust accumulated in the measuring device 100, the value at that time becomes zero. By performing this zero correction processing, subsequent processing is simplified, but it is not necessary to perform the zero correction processing. In this case, the value before the napkin is inserted into the measuring device 100 may be stored, and the difference from the value after insertion may be obtained.

[0033] In step S103, the control unit 180 determines whether the reading unit 165 has already acquired the ID information. If not, it maintains that state, and if it has, it proceeds to step S104.

[0034] In step S104, the control unit 180 controls the drive unit 130 to open the lid unit 120. As a result, the user can discard the used napkin into the measuring device 100.

[0035] In step S105, the control unit 180 determines whether it is acquiring a detection signal from the optical sensor 140. If it continues to acquire, it maintains that state, and if the acquisition stops, it proceeds to step S106. At this time, the control unit 180 may proceed to step S106 after a first predetermined time (for example, 1 second or more and 5 seconds or less) after the acquisition of the detection signal stops.

[0036] In step S106, the control unit 180 controls the drive unit 130 to close the lid unit 120. In this way, the user can open and close the lid unit 120 without touching the measuring device 100. That is, the user can open and close the lid unit 120 without touching the measuring device 100 while holding the used napkin.

[0037] In step S107, the control unit 180 waits for a second predetermined time (for example, 0.5 seconds or more and 2 seconds or less) and then proceeds to step S108. Thereby, the vibration generated by operating the lid portion 120 can be reduced. That is, it is possible to suppress the destabilization of the weight measurement due to the vibration.

[0038] In step S108, the control unit 180 controls the weight sensor 160 to measure the current weight.

[0039] In step S109, the control unit 180 controls the communication unit 170 to transmit the measurement result of the weight sensor 160, the measurement time thereof, and the ID information to the information notification device 200 and / or the server device 300, and proceeds to step S101. If the transmission cannot be executed, the control unit 180 may transmit error information to the information notification device 200 and / or the server device 300.

[0040] In step S110, the control unit 180 determines whether or not a third predetermined time (for example, 24 hours or more and 72 hours or less) has elapsed since the previous acquisition. If not, it proceeds to step S101. If it has elapsed, the process ends. By this end, the power is turned off, and it is possible to suppress excessive power consumption. Note that it is preferable that the first predetermined time, the second predetermined time, and the third predetermined time satisfy the relationship of the third predetermined time > the first predetermined time > the second predetermined time.

[0041] Next, the information notification device processing method will be described. The information notification device processing method may be implemented by an application or by a WEB browser. The information notification device processing method includes a physiological information acquisition method and a next physiological estimation method.

[0042] The physiological information acquisition method is a method for acquiring physiological information related to the user's physiology. The physiological information includes the weight of menstrual blood contained in the napkin, the type of the napkin containing the menstrual blood, and the measurement time of the weight of the menstrual blood. Here, the weight of the menstrual blood is an example of the menstrual blood volume. The menstrual blood volume also includes the volume of the menstrual blood. For example, it is possible to convert the weight of the menstrual blood into the volume of the menstrual blood using the specific gravity of the blood or the like and obtain it.

[0043] The next physiological estimation method is a method for estimating the user's next physiological state based on the physiological information acquired by the physiological information acquisition method.

[0044] First, the physiological information acquisition method will be described. FIG. 7 is a flowchart showing the physiological information acquisition method according to the embodiment.

[0045] As shown in FIG. 7, in step S201, the control unit 270 acquires search information. The search information here is information for searching for the napkin used by the user. As described above, the search information can be acquired from at least one of the touch panel unit 210, the voice input unit 230, and the imaging unit 250 of the information notification device 200.

[0046] In step S202, the control unit 270 controls the communication unit 260 to access the database in the server device 300 and determines whether a napkin corresponding to the search information exists in the database. If the control unit 270 determines that the napkin corresponding to the search information does not exist in the database, it proceeds to step S203; if it determines that it exists, it proceeds to step S210.

[0047] In step S203, the control unit 270 controls the touch panel unit 210 to prompt and allow the user to select from the touch panel unit 210 whether to register a new napkin in the database. When it is input from the touch panel unit 210 that registration is to be performed, the control unit 270 proceeds to step S204; when it is input from the touch panel unit 210 that registration is not to be performed, the control unit 270 proceeds to step S207. Note that the control unit 270 displays an option for registration on the touch panel unit 210 only when the user has the registration authority. For a user without the registration authority, the control unit 270 automatically proceeds to step S207 without accepting input from the user.

[0048] In step S204, the user operates the touch panel unit 210 to input registration information regarding a new napkin. When the input is completed, the control unit 270 controls the communication unit 260 to transmit the acquired registration information to the server device 300. As a result, the registration information is registered in the database in the server device 300. After transmitting the registration information, the control unit 270 proceeds to step S211. Here, the registration information may be registered in a personal database or a shared database.

[0049] In step S207, the control unit 270 controls the communication unit 260 to access the database in the server device 300, extract and acquire napkins similar to the search information. In this case, a search process with lower accuracy than the search process in step S202 (for example, fuzzy search, semantic search, etc.) is performed. After extracting the similar napkins, the control unit 270 proceeds to step S211.

[0050] In step S210, the control unit 270 controls the communication unit 260 to acquire information on the napkin corresponding to the search information from the database.

[0051] In step S211, the control unit 270 controls the touch panel unit 210 to display the acquired information (the registration information in step S204, the information on the similar napkins in step S207, and the information on the napkin corresponding to the search information in step S210).

[0052] FIG. 8 is an explanatory diagram showing a display example on the information notification device 200 according to the embodiment. As shown in FIG. 8, the acquired napkin information (company name, brand name, size, classification, features), the OK button B11, and the NG button B12 are displayed on the touch panel unit 210.

[0053] In step S212, when the OK button B11 is touched, the control unit 270 proceeds to step S216, and when the NG button B12 is touched, the control unit 270 proceeds to step S213.

[0054] In step S213, the control unit 270 controls the touch panel unit 210 to prompt the user to select whether to re-enter the search information or not. If the user selects to re-enter the search information, the control unit 270 proceeds to step S201; if the user does not select to re-enter, the control unit 270 proceeds to step S214.

[0055] In step S214, the control unit 270 controls the communication unit 260 to access the database in the server device 300 and obtain information on a plurality of napkins that match part of the search information. The control unit 270 controls the touch panel unit 210 to display the information on the plurality of napkins in a selectable manner for the user. The user selects the napkin they used by operating the touch panel unit 210.

[0056] In step S215, the control unit 270 obtains the weight before use from the information on the napkin selected by the user and proceeds to step S217.

[0057] Specifically, in steps S214 and S215, at least one candidate for the napkin used by the user is extracted by a search based on the search information, and the extracted candidate is displayed on the touch panel unit 210. Then, among the at least one candidate, the user selects the napkin actually used. After that, the weight of the selected napkin after use is obtained. If the napkin actually used by the user is not selected among the at least one candidate, the control unit 270 may execute an acceptance process for accepting the registration of a new napkin. In the acceptance process, for example, the same processing as in step S204 is performed.

[0058] In step S216, the control unit 270 obtains the weight of the napkin before use from the information on the napkin when the OK button B11 is touched.

[0059] In step S217, the control unit 270 acquires, by controlling the communication unit 170, the measurement result of the weight sensor 160 (the weight of the used napkin) transmitted from the measurement device 100.

[0060] In step S218, the control unit 270 obtains the weight of the user's menstrual blood by subtracting the weight of the napkin before use from the weight of the napkin after use.

[0061] In step S219, the control unit 270 associates the obtained weight of the menstrual blood, the type of the napkin containing the menstrual blood, and the measurement time of the weight of the menstrual blood, and acquires these as physiological information.

[0062] In step S220, the control unit 270 controls the touch panel unit 210 to display the physiological information, thereby notifying the user (physiological information notification step). Note that the control unit 270 may control the sound output unit 220 to perform notification by sound.

[0063] In step S221, the control unit 270 stores the physiological information as a log in the storage unit 240 and ends the physiological information acquisition method. Thus, the physiological information acquisition method is an example of a physiological information acquisition step for acquiring physiological information related to the user's physiology.

[0064] Next, the next physiological estimation method will be described. FIG. 9 is a flowchart showing the next physiological estimation method according to the embodiment.

[0065] In step S301, the control unit 270 estimates the tendency of the user's next physiology based on the log of the physiological information stored in the storage unit 240 (physiological tendency estimation step). Specifically, the control unit 270 estimates the tendencies such as the start time, end time, and change in the weight of the menstrual blood of the next physiology based on a plurality of physiological information included in the log.

[0066] In step S302, based on the estimated next physiological trend, the control unit 270 estimates the planned usage quantity for each at least one type of napkin that the user can use during the next physiological period (planned usage quantity estimation step). Here, at least one type of napkin that the user can use can be estimated based on the types of napkins included in the past physiological information.

[0067] Note that it is not necessarily required to estimate the planned usage quantity based on the next physiological estimation method. For example, since there is no past physiological information for the first physiological period when the device is used, the planned usage quantity may be estimated based on the menstrual blood information for that month. Also, there may be no physiological information for one cycle due to device failure, replacement, long-term travel, etc., and the previous measurement value may simply be used as it is instead of the next physiological estimation method.

[0068] In step S303, the control unit 270 controls the touch panel unit 210 to display the planned usage quantity of each type of napkin during the user's next physiological period, thereby notifying the user.

[0069] FIG. 10 is an explanatory diagram showing an example of the display of the planned usage quantity in the information notification device 200 according to the embodiment. As shown in FIG. 10, in the touch panel unit 210, the planned usage quantity for each at least one type of napkin (for example, napkin A, napkin B, napkin C) that the user can use is displayed in a list. Thus, in this embodiment, the information notification device 200 has the functions of the acquisition device, estimation device, and notification device according to the present disclosure. Note that the acquisition device, estimation device, and notification device may each be a dedicated device.

[0070] Note that in this embodiment, the case where the physiological information is stored as a log in the storage unit 240 of the information notification device 200 is exemplified, but the sorted information for each user may be stored as a log in the server device 300. In this case, the planned usage quantity for each next physiological supply for each user is estimated by the server device 300, and the estimation result is transmitted to the information notification device 200 and notified by the information notification device 200.

[0071] (Effects, etc.) As described above, according to the present embodiment, based on the estimated next physiological tendency of the user, at the time of the next physiological period, the estimated number of planned uses for each at least one type of napkin that the user can use is estimated and notified. Therefore, before the next physiological period, the user can be made aware of the planned number of uses for each type of napkin. As a result, the user can check in advance the remaining quantity of each type of napkin and can replenish the insufficient napkins.

[0072] Since the physiological information includes the type of napkin used by the user, the menstrual blood volume on the napkin, and the measurement time of the menstrual blood volume, it is possible to more accurately estimate the tendency of the next physiological period based on the type of napkin, the menstrual blood volume, and the measurement time.

[0073] [Modification Example] Hereinafter, each modification example of the above embodiment will be described. In the following description, the same parts as those in the above embodiment or other modification examples may be denoted by the same reference numerals and the description thereof may be omitted.

[0074] (Modification Example 1) In Modification Example 1, a display example of physiological information will be described. FIG. 11 is an explanatory diagram showing a display example of physiological information according to Modification Example 1. As shown in FIG. 11, the touch panel unit 210 of the information notification device 200 is provided with a physiological information display unit 211, a total menstrual blood volume display unit 212, and an editing operation unit 213.

[0075] The physiological information display unit 211 is disposed in the middle part in the vertical direction of the touch panel unit 210, and for example, the physiological information of each type of napkin used in one (one cycle) of menstruation is displayed in a list. In FIG. 11, the physiological information display unit 211 is provided with a scroll bar 214, and the physiological information outside the physiological information display unit 211 can be displayed in the physiological information display unit 211 by operating the scroll bar 214.

[0076] In the physiological information display unit 211, the type of napkin used by the user (for example, napkin A), the measurement time (for example, 2023 / 12 / 30 12:00), and the menstrual blood volume (weight of menstrual blood: 90 g) are grouped in one column and arranged in chronological order.

[0077] The total menstrual blood volume display unit 212 is arranged above the physiological information display unit 211, and the total menstrual blood volume in one menstruation is displayed. The total menstrual blood volume is the value obtained by integrating the menstrual blood volumes of each napkin displayed in the physiological information display unit 211.

[0078] The editing operation unit 213 is an operation unit for editing the physiological information in each column of the physiological information display unit 211. The editing operation unit 213 is provided with a delete button B21, a modify button B22, an add button B23, and an OK button B24.

[0079] The delete button B21 is a button for deleting the physiological information in the physiological information display unit 211. Specifically, when the delete button B21 is touched when there is a selected column in the physiological information display unit 211, the control unit 270 deletes the physiological information in the column.

[0080] The modify button B22 is a button for editing the physiological information in the physiological information display unit 211. Specifically, when the modify button B22 is touched when there is a selected column in the physiological information display unit 211, the control unit 270 controls the touch panel unit 210 and transitions to the search screen.

[0081] FIG. 12 is an explanatory diagram showing an example of a search screen according to Modification 1. As shown in FIG. 12, the search screen is provided with a text box T51, a search button B52, a search result column T53, an OK button B85, and a cancel button B86.

[0082] Text for text search is input into the text box T51. In the example of FIG. 12, "20 cm" and "noon" are input into the text box T51. The input content of this text box T51 is an example of search information.

[0083] When the search button B52 is touched in this state, the control unit 270 of the information notification device 200 controls the communication unit 260 to access the server device 300 and search the database based on the search information. In this search, it is possible to extract the napkins that exactly match the search information, or to extract the napkins that satisfy a predetermined condition with respect to the search information.

[0084] The control unit 270 controls the touch panel unit 210 to display the information of the extracted napkins in a list in the search result column T53. When the package image of the napkin is also registered in the database, the package image may also be displayed as the information of the napkin. The control unit 270 provides a check box T56 for the information of each napkin. When only one napkin is extracted, the display of the check box T56 may be omitted.

[0085] The user checks by touching the check box T56 after selecting one of the napkins he / she has used by checking the search result column T53. Then, the user touches the OK button B85. Thereby, the control unit 270 recognizes the napkin that the user has used.

[0086] In addition, when the user checks the search result column T53 and there is no napkin he / she has used, the user touches the cancel button B86 to end the search process. In addition to editing the type of napkin, it is also possible to edit the measurement time and the menstrual blood volume.

[0087] The add button B23 in FIG. 11 is a button for newly adding physiological information. For example, it is assumed that there are situations where the user cannot discard the napkin in the measuring device 100, such as when the user exchanges the napkin while away from home. In such a case, the user can add the physiological information of the napkin that could not be discarded in the measuring device 100 by operating the add button B23. Specifically, when the add button B23 is touched, the control unit 270 controls the touch panel unit 210 to transition to the search screen shown in FIG. 12. When the napkin to be added is selected on the search screen, the control unit 270 then controls the touch panel unit 210 to display an input screen for the measurement time and the menstrual blood volume. The user operates the input screen to input the measurement time and the menstrual blood volume, thereby adding the physiological information of the new napkin.

[0088] The OK button B24 in FIG. 11 is a button for accepting the user's approval for the physiological information listed in the physiological information display unit 211. Specifically, when the OK button B24 is touched, the control unit 270 reflects the physiological information listed in the physiological information display unit 211 in the log of the physiological information stored in the storage unit 240.

[0089] In this way, since the editing of physiological information by the user is accepted, more accurate physiological information can be obtained. As a result, the tendency of the next menstruation can be estimated more accurately, and ultimately, the planned usage quantity for each napkin can also be estimated more accurately.

[0090] (Modification Example 2) In Modification Example 2, the storage quantity acquisition process executed by the information notification device 200 will be described.

[0091] In the storage quantity acquisition process, the information notification device 200 acquires the storage quantity for each type of napkin that the user can use. In the storage quantity acquisition process, the user may operate the information notification device 200 and input manually to acquire the storage quantity for each type of napkin.

[0092] In the storage quantity acquisition process, the user may operate the information notification device 200 to obtain the storage quantity for each type of napkin based on the captured image obtained by photographing the inside of the napkin storage. Specifically, the control unit 270 can perform image recognition processing on the captured image to recognize and acquire the storage quantity for each type of napkin.

[0093] Also, the control unit 270 may obtain the usage quantity of each type of napkin used in one physiological process based on the log of physiological information stored in the storage unit 240 (usage quantity acquisition process). In the storage quantity acquisition process, the storage quantity after this physiological process is obtained by subtracting the usage quantity from the storage quantity of each type of napkin up to the previous time. Thereby, the storage quantity of each type of napkin will be automatically updated, and the storage quantity can be efficiently managed.

[0094] Furthermore, the control unit 270 may estimate the planned difference by subtracting the planned usage quantity from the storage quantity of each type of napkin after this physiological process (difference estimation process).

[0095] The control unit 270 may control the touch panel unit 210 to display and notify the user of the storage quantity, usage quantity, planned difference, and planned usage quantity of each type of napkin. FIG. 13 is an explanatory diagram showing an example of the display of the estimated transition of each napkin according to Modification 2. In FIG. 13, "Storage" indicates the storage quantity up to the previous time, "This time" indicates the usage quantity in this physiological process, "Remaining quantity" indicates the difference obtained by subtracting the usage quantity from the storage quantity, "Next time" indicates the planned usage quantity in the next physiological process, and "Shortage" indicates the planned difference. Note that "Shortage" indicates the absolute value (shortage number) when the planned difference is negative. When the planned difference is positive, it may be expressed as 0 or a blank, or it may be expressed with a different color from the shortage number, for example, to indicate that it is a surplus quantity. When there is a shortage, a message prompting the user may be separately notified.

[0096] In this way, since the shortage as the planned difference of various types of sanitary napkins is notified to the user in advance, the user can grasp the storage status of each sanitary napkin before the next menstruation, and can also replenish it if there is a shortage of sanitary napkins.

[0097] (Modification Example 3) In Modification Example 3, a specific method in the physiological tendency estimation step will be described. As described above, in the physiological tendency estimation step, the control unit 270 estimates tendencies such as the start time, end time, and change in menstrual blood volume of the next menstruation based on a plurality of logs included in the log.

[0098] FIG. 14 is an image diagram of the method for estimating the menstrual blood volume according to Modification Example 3. Specifically, the control unit 270 classifies the physiological information into physiological information for each cycle from the log of the physiological information stored in the storage unit 240, and acquires graphs (graphs G11 to G13 in FIG. 14) showing the relationship between time and menstrual blood volume. The control unit 270 creates a model M11 by simply averaging each graph.

[0099] Next, the control unit 270 obtains the total menstrual blood volume for each cycle, and creates a graph G14 showing the relationship between the cycle and the total menstrual blood volume. The total menstrual blood volume at the next menstruation (next cycle) is estimated from the moving average of the total menstrual blood volume for each cycle (estimated value T15 in G14). For example, the estimated value T15 is 110% of the average value of the past total menstrual blood volume. The control unit 270 creates an estimation model M12 by integrating this 110% with respect to the model M11. Thereby, the menstrual blood volume at each time of the next menstruation can be estimated.

[0100] FIG. 15 is an image diagram of a method for estimating the start time and end time of menstruation according to Modification 3. As shown in FIG. 15, the control unit 270 arranges the menstrual blood volumes of each past cycle in time series based on the log of physiological information. Thereby, the control unit 270 obtains the menstrual periods T11 to T14 and the non-menstrual periods T21 to T23 of each cycle, and calculates the average value of the menstrual periods and the average value of the non-menstrual periods. The control unit 270 can estimate the start time of the next menstruation by adding the average value of the non-menstrual period to the end time of the current menstruation. Further, the control unit 270 can estimate the end time of the next menstruation by adding the average value of the menstrual period to the start time of the next menstruation.

[0101] Note that instead of simply adopting the average value, the next menstrual period may be estimated based on an approximation model such as a moving average of the menstrual periods of each cycle. This also applies to the non-menstrual period. The approximation model may be created by an approximation method other than the moving average (for example, linear approximation, polynomial approximation, etc.).

[0102] Also, in the estimation of any of the change in menstrual blood volume, the start time, and the end time of menstruation, data of a person other than the user may be used. For example, a clustering method may be used to determine which group the user belongs to, and the estimation may be made based on the average pattern of the group.

[0103] (Modification 4) In Modification 4, a specific method in the estimated usage quantity estimation step will be described. As described above, in the estimated usage quantity estimation step, the control unit 270 estimates the estimated usage quantity for each at least one type of napkin that the user can use during the next menstruation based on the estimated tendency of the next menstruation.

[0104] FIG. 16 is an image diagram of a method for estimating the planned number of uses per napkin according to Modification 4. Here, the control unit 270 has previously controlled the communication unit 260 to obtain the absorption amounts of various types of napkins that can be used by the user. The control unit 270 selects a corresponding napkin based on the menstrual blood volume at each time during the next menstrual period included in the estimation model M12. Specifically, the menstrual blood volume at each time in the estimation model M12 is classified using a first threshold value and a second threshold value that is greater than the first threshold value. The first threshold value is, for example, 20 g, and the second threshold value is, for example, 80 g. For a menstrual blood volume that is less than or equal to the first threshold value, a napkin that exceeds the first threshold value to some extent (in this embodiment, napkin C with an absorption amount of 35 g) is selected. For a menstrual blood volume that is greater than the first threshold value and less than the second threshold value, a napkin that exceeds the second threshold value to some extent (in this embodiment, napkin A with an absorption amount of 85 g) is selected. For a menstrual blood volume that is greater than the second threshold value, a napkin that greatly exceeds the second threshold value (in this embodiment, napkin B with an absorption amount of 100 g) is selected. In the example of FIG. 16, the planned number of uses of napkin A is 3, the planned number of uses of napkin B is 2, and the planned number of uses of napkin C is 1.

[0105] When notifying the planned number of uses of each napkin with the information notification device 200, the order of use may also be included in the notification. The order of use is, for example, in the order of napkin A, napkin B, napkin B, napkin A, napkin A, napkin C in FIG. 16. This enables the user to recognize the order of use of each napkin as well.

[0106] (Modification 5) In Modification 5, an ordering process for receiving and placing an order for the missing napkins will be described. FIG. 17 is an explanatory diagram showing an example of an ordering screen according to Modification 5. FIG. 17 adds display objects for ordering to the display example of the estimated transition of each napkin shown in FIG. 13. Specifically, in the ordering process, the control unit 270 controls the touch panel unit 210 to display a first change button B81, a second change button B82, an OK button B53 for purchase confirmation, a NO button B54, and the like. The first change button B81 is a button for changing the "shortage" item. When this first change button B81 is touched, each column of "shortage" becomes editable. Since the value in each column of "shortage" indicates the shortage quantity of each napkin, the shortage quantity becomes the order quantity of each napkin.

[0107] The second change button B82 is a button for changing the delivery time. When this second change button B82 is touched, the delivery time becomes editable. Near the second change button B82, the start time of the next menstruation and the delivery time are displayed. The user can adjust the delivery time while checking the start time of the next menstruation.

[0108] The OK button B53 for purchase confirmation is a button for finalizing the order, and the NO button B54 is a button for canceling the order. When the OK button B53 is touched, the control unit 270 controls the communication unit 260 to transmit the order quantity of each napkin to the server device 300. At this time, the control unit 270 may control the touch panel unit 210 to display an input screen for the user's personal information (name, address, phone number, credit card number) required for the order, and transmit the input result to the server device 300. If the personal information is registered in advance, the control unit 270 may control the touch panel unit 210 to display an input screen for the user's ID and password.

[0109] In this way, in the ordering process, since the order for the missing type of napkin is received and placed, the trouble for the user to prepare the napkin can be suppressed. In particular, since the missing type of napkin is automatically determined, it is more efficient.

[0110] On the manufacturer side, since napkins are purchased regularly, it becomes easier to manage production and inventory. In addition to this, storage and transportation costs and intermediate margins can also be reduced, and as a result, it is possible to make napkins cheaper.

[0111] In addition, in the ordering process, in addition to the number of ordered items, the usage time assumed for each napkin (each time at the next menstruation included in the above-described estimation model M12) may also be transmitted to the server device 300. Thereby, the order receiver can also pack and ship each napkin arranged in the order of use. FIG. 18 is an explanatory view showing a packing example according to Modification 5. As shown in FIG. 18, in the packing material D, napkins A, B, and C are arranged in the order of use. Note that as long as the order of use is known, the arrangement method of the napkins may be any. Thereby, even if the user does not remember the order of use, the user can easily use the napkins according to the order of use at the next menstruation.

[0112] Furthermore, the information notification device 200 may display the order of use of each napkin based on the start time of the next menstruation. The user can confirm the order of use of each napkin by visually recognizing the display.

[0113] (Modification 6) In Modification Example 6, the case of modifying the planned usage quantity of each napkin during the next menstruation will be described. FIG. 19 is an image diagram of a method for modifying the planned usage quantity for each napkin according to Modification Example 6. In FIG. 19, during the next menstruation, the menstrual blood volume is actually measured from the first to the third time. When the difference between the actual measurement value and the estimated value is equal to or greater than a predetermined value, the control unit 270 re-estimates the menstrual blood volume thereafter. At this time, the control unit 270 estimates considering also the actual measurement values of the menstrual blood volume from the first to the third time. Thereby, the menstrual blood volume for the next three times is estimated (illustrated by a white bar graph in FIG. 19). The planned usage quantities were 3 for Napkin A, 2 for Napkin B, and 1 for Napkin C before the modification, but become 2 for Napkin A, 3 for Napkin B, and 1 for Napkin C after the modification. When there is a change in the planned usage quantity before and after the modification, the control unit 270 may control the touch panel unit 210 to notify the user to that effect. At this time, when a newly insufficient napkin occurs, the control unit 270 may control the touch panel unit 210 to display a prompt for the user to place a new order. Alternatively, the control unit 270 may automatically place an order to supplement the newly occurred shortage.

[0114] (Modification Example 7) In Modification Example 7, the case of also notifying the absorption amount of the napkin will be described. As described above, the control unit 270 controls the communication unit 260 to acquire the absorption amounts of various types of napkins that the user can use (absorption amount acquisition step). The control unit 270 estimates the ratio of the menstrual blood volume to the absorption amount based on the estimated menstrual blood volume and the absorption amount of the napkin that absorbs this menstrual blood volume (ratio estimation step). The control unit 270 controls the touch panel unit 210 to notify the user of the ratio (ratio notification step).

[0115] FIG. 20 is an explanatory diagram showing an example of displaying the ratio according to Modification Example 7. In FIG. 20, a bar graph G71 showing the maximum absorption amount is displayed. In this bar graph G71, the menstrual blood volume of the napkin is superimposed and displayed, and the ratio is displayed above the bar graph G71. A warning may be displayed when the menstrual blood volume exceeds a predetermined ratio (for example, 75%) with respect to the absorption amount.

[0116] Furthermore, it is also possible to estimate the blood loss per unit time from the trend of past blood loss amounts. In this case, the control unit 270 can also estimate and notify the ratio of the user's actual used napkin, and can also notify the change of the ratio in substantially real time. Thereby, the user can be prompted to change the napkin before the blood loss amount exceeds the absorption amount of the napkin. The control unit 270 can also estimate the timing of changing the napkin by estimating the time period when the blood loss amount exceeds the absorption amount of the napkin.

[0117] The blood loss amount per unit time can be calculated from the measured value of the blood loss amount. Since the blood loss amount and the measurement timing are associated with each other, for example, based on the interval between the measurement timing at the first replacement and the measurement timing at the second replacement, and the blood loss amount at the second replacement, the blood loss amount per unit time can be calculated. When the interval is 5 hours and the blood loss amount at the second replacement is 100 g, the blood loss amount per hour is 100 g÷5 hours = 20 g. In addition, by plotting each replacement timing and each blood loss amount on a graph and creating an approximation model, it is also possible to obtain the blood loss amount per unit time more precisely.

[0118] In the database of the server device 300, the absorption amount (absorption rate) per unit time of each napkin may be stored. By using the absorption rate and the blood loss amount per unit time, more complex estimation becomes possible.

[0119] (Modification Example 8) In Modification 8, the case where the absorption amount of the napkin is indicated by a mark will be described. FIG. 21 is a table showing an example of the mark according to Modification 8. As shown in FIG. 21, the absorption amount is classified into a group G81 of 0 to 15 g, a group G82 of 15 to 30 g, a group G83 of 30 to 45 g, and a group G84 of 30 g or more. In each group, a mark that can intuitively image the magnitude of the absorption amount is set (in the case of FIG. 21, a mark that can imagine the amount of rainfall). Further, by surrounding the mark with a circle, a group with wings (for example, group G85) is expressed. When each napkin is displayed on the touch panel unit 210, the mark can also be displayed together to intuitively convey the absorption amount of the napkin. This mark may also be used on the napkin package, product description, etc. Such a mark may be standardized and used among multiple manufacturers.

[0120] (Modification 9) In Modification 9, the schedule acquisition step of acquiring the user's schedule will be described. The schedule acquisition step acquires the schedule registered by the user in the information notification device 200. The schedule may be registered by the user inputting it into the application, or may be registered by importing part or all of the data of another scheduler.

[0121] FIG. 22 is an explanatory diagram showing an example of the schedule according to Modification 9. As shown in FIG. 22, hatching is applied to the time zone where there is an item registered in the schedule. The control unit 270 estimates the time zone where the item is registered as a non-exchangeable time zone where the napkin cannot be exchanged, and estimates the time zone where the item is not registered as an exchangeable time zone where the napkin can be exchanged (exchangeability estimation step). Note that the control unit 270 may estimate the non-exchangeable time zone or the exchangeable time zone based on the content of the item. The control unit 270 controls the touch panel unit 210 to display and notify the determination result (exchangeability notification step).

[0122] In this way, in the replacement availability notification process, the non-replaceable time period or the replaceable time period is notified based on the schedule, so that the user can grasp the non-replaceable time period or the replaceable time period in advance.

[0123] Note that the determination of the non-replaceable time period or the replaceable time period can be made according to the importance of the content of the item. Contents with high importance (such as meetings, going out, sleeping, etc.) are set as non-replaceable time periods, and contents with low importance (such as lunch) are set as replaceable time periods. The non-replaceable time period and the replaceable time period may be edited by the user.

[0124] When the number of times and the ratio that the estimated replacement time period is included in the non-replaceable time period exceed a predetermined value, the control unit 270 may inquire the user whether it is possible to switch the non-replaceable time period to a replaceable time period.

[0125] Also, the available time period and the unavailable time period of the measuring device 100 may be registered in the schedule. For example, when the measuring device 100 is installed only at home, it may be registered as an unavailable time period when going out and an available time period when at home. Based on the current position of the user (the position information of the information notification device 200), the available time period and the unavailable time period may be registered in the schedule. For example, even if it is an unavailable time period, when information is transmitted from the measuring device 100 to the information notification device 200, since information of others may be transmitted or the transmission is caused by noise, it is also possible for the information notification device 200 to perform a display prompting the user to confirm the information.

[0126] The situation, physical condition, behavior, etc. at the time of changing the napkin may be registered in the schedule. Thereby, since the replacement time, the menstrual volume, the situation, the physical condition, and the behavior are associated, it becomes possible to analyze by checking the schedule.

[0127] FIG. 23 is an explanatory diagram showing an example of a schedule according to Modification 9. In FIG. 23, time and the actions performed by the user at that time are arranged side by side. The square frame w1 surrounding these indicates the replacement of the napkin. The actions performed by the user are indicated by icons imitating the actions. Below the icons, the user's situation at that time and the like are described. When the user is wearing a wearable terminal, based on the signals detected by various sensors provided in the wearable terminal, the user's actions may be estimated and the actions may be automatically registered in the schedule. Alternatively, the estimated actions may be notified to the user to prompt confirmation.

[0128] Also, the variation in the menstrual blood volume may be shown according to the schedule. FIG. 24 is an explanatory diagram showing an example of a schedule according to Modification 9. The line graph G91 shown in FIG. 24 shows the variation in the menstrual blood volume. In the line graph G91, the measured values are indicated by the thick line g92, and the estimated values are indicated by the thin line g93.

[0129] Below the line graph G91, the type of napkin in each time zone, the absorption amount of the napkin, the menstrual blood volume at the time of replacement, and the usage rate of the napkin at the time of replacement are shown in a table. The schedule is shown below the table.

[0130] Between the line graph G91 and the table, the usage times and usage rates of each napkin are indicated by arrows Y91 to Y97. The thickness of the arrows Y91 to Y97 is determined according to the usage rate of each napkin. The arrows Y91, Y92, Y93, and Y96 whose tips have entered the replaceable time zone are white. In contrast, the arrows Y94, Y95, and Y97 whose tips have entered the non-replaceable time zone are colored dark. In particular, for arrow Y94, since the usage rate exceeds a predetermined ratio (for example, 75%), it is colored darker. In this case, the information notification device 200 may display a warning such as "There is a high possibility of leakage if not replaced. The usage rate is 90% at 13:30. It is expected that the usage rate will reach 100% around 14:10." Furthermore, the information notification device 200 may estimate the menstrual blood volume when exceeding the non-replaceable time zone, and select at least one candidate napkin that can absorb the menstrual blood volume. By the information notification device 200 notifying the user of the selected at least one candidate napkin in advance, it is also possible for the user to prepare in advance. If no candidate can be selected, the information notification device 200 may notify the user to that effect. Even in this case, the user can take countermeasures in advance.

[0131] (Modification Example 10) In Modification Example 10, other information stored in the database will be described. For example, in the database, for each type of napkin, price information, sales share information, evaluation information, user information, etc. can be cited. The price information includes the manufacturer's desired retail price, the average price in the market, the lowest price, etc. Thereby, statistical values such as the total amount and average value of the napkins used by the user can be estimated, and cost analysis is possible. Furthermore, it is also possible to propose a napkin that prioritizes cost to the user. For example, in the estimated usage quantity prediction step, the control unit 270 extracts at least one napkin that prioritizes cost, estimates the planned usage quantity of each napkin during the next menstruation, and proposes it.

[0132] The sales share information includes the share of each napkin in the market, etc. Thus, it is also possible to propose napkins with a high share to the user. For example, in the estimated number of planned uses step, the control unit 270 extracts at least one napkin with priority given to the share, estimates the estimated number of planned uses of each napkin for the next menstruation, and proposes it.

[0133] The evaluation information is the evaluation from the user for each napkin, and includes, for example, the presence or absence of leakage, the situation at the time of leakage occurrence, the feelings towards the napkin, etc. Thus, it is also possible to propose napkins with priority given to the evaluation to the user. For example, in the estimated number of planned uses step, the control unit 270 extracts at least one napkin with priority given to the evaluation, estimates the estimated number of planned uses of each napkin for the next menstruation, and proposes it.

[0134] The user information is information indicating the characteristics of the user using each napkin, and includes, for example, the presence or absence of PMS (premenstrual syndrome), body temperature, etc. Thus, it is possible to make a proposal according to the characteristics of the user. For example, in the estimated number of planned uses step, the control unit 270 extracts at least one napkin according to the characteristics of the user, estimates the estimated number of planned uses of each napkin for the next menstruation, and proposes it.

[0135] These information can be registered in the database by each user, administrator, system, etc. The information stored in the database may be shared among multiple users.

[0136] (Modification Example 11) In Modification Example 11, an example of simplifying the registration of a schedule will be described. FIG. 25 is an explanatory diagram showing an example of a schedule registration screen according to Modification Example 11. As shown in FIG. 25, on this registration screen, three selection buttons B31, B32, and B33 are provided for each of the morning, noon, and night. With selection button B31, it is possible to select the case where it is almost impossible to change the napkin during that time period. With selection button B32, it is possible to select the case where the napkin can be changed limitedly during that time period. With selection button B33, it is possible to select the case where the napkin can be changed at a free time during that time period. By the user selecting one selection button B31, B32, or B33 for each of the morning, noon, and night, the general situation of each time period can be registered. Also, on the registration screen, the assumed going-out time can be inputted.

[0137] (Modification Example 12) In Modification Example 12, the case where a plurality of candidate napkins are proposed will be described. FIGS. 26 to 28 are explanatory diagrams showing an example of a proposal screen according to Modification Example 12. On the proposal screen, a current situation screen G21 and a proposal screen G22 are displayed. On the current situation screen G21, the estimated daily menstrual blood volume of the user and the durability time per sheet of each napkin currently used by the user that can absorb that menstrual blood volume are displayed.

[0138] On the proposal screen G22, a plurality of tabs t1, t2, and t3 that can switch each candidate are provided. With tab t1, candidates for napkins that prioritize the number of times are displayed. With tab t2, candidates for thin napkins are displayed. With tab t3, napkins that prioritize economy are displayed. The control unit 270 selects napkin candidates based on the information of each napkin stored in the database and the estimated menstrual blood volume of the user so as to correspond to one selected tab. After the selection, the proposed content is displayed on the proposal screen G22.

[0139] For example, in FIG. 26, the proposed content when tab t2 is selected is displayed on the proposal screen G22. In FIG. 27, the proposed content when tab t3 is selected is displayed on the proposal screen G22. In FIG. 28, the current screen G21 and the proposal screen G22 when the menstrual blood volume is less than that in FIG. 26 are illustrated. Currently, the number and cost estimated when each sanitary napkin currently used by the user is adopted as it is during the next menstruation may be compared with the number and cost estimated when each candidate is adopted during the next menstruation and displayed.

[0140] In each proposed content, an order candidate for a sanitary napkin of a different type from the sanitary napkins the user has used so far is proposed. When the user selects any of the order candidates, the sanitary napkins of the selected order candidate are ordered. That is, in the ordering process, order candidates for sanitary napkins of different types are proposed to the user and made orderable. Thereby, sanitary napkins that meet the user's requirements can be ordered. Note that in the ordering process, sanitary products other than sanitary napkins may be used as order candidates.

[0141] (Modification Example 13) In Modification Example 13, the case where a plurality of users are clustered will be described. In the database, it is also possible to register the physiological information of a plurality of users in association with physical information (height, weight, age, race, lifestyle information, etc.). Using a well-known clustering method such as the k-means method, for example, the physiological information and the physical information are used to group a plurality of users. Thereby, when estimating the planned usage number of each sanitary napkin during the next menstruation, it is also possible to estimate using the basic model of the group to which the user belongs. The basic model may be the average pattern of a plurality of users included in the group, or other common patterns. In this case, even for users with less logging, the planned usage number during the next menstruation can be estimated more accurately.

[0142] Furthermore, a transition model between each group may be created, and the user's time pattern may be estimated based on the transition model. FIG. 29 is an image diagram of the estimation using the transition model according to Modification 13. First, clustering is performed based on the physiological information and body information of a plurality of other users. Thereby, a model for each pattern of physiological information is created. A transition model M21 is created from the transition data of the model. In the transition model M21, the probability of transitioning from pattern P1 to pattern P2 is 70%, and the probability of transitioning to other patterns is 30%.

[0143] Next, based on the physiological information and body information of the user, the group to which the user belongs is selected, and the transition model M21 is applied. As described above, in the transition model M21, since the probability of transitioning from pattern P1 to pattern P2 is high, when the user is in pattern P1, it is estimated that the user will transition to pattern P2.

[0144] (Modification 14) In Modification 14, the case of estimating the missing part when there is a missing amount of menstrual blood will be described. For example, due to forgetting to measure or deleting measurement data, there may be a missing part in the log of physiological information. FIG. 30 is an explanatory diagram showing the graph G41 with a missing part according to Modification 14. In FIG. 30, the broken-line bar graph G42 is the part that was originally missing, but by estimating the amount of menstrual blood in the missing part from the physiological information before and after that, the broken-line bar graph G42 is supplemented. In this estimation, the result of clustering may also be used. The content after estimation may be made editable. Furthermore, the total amount and variation of the menstrual blood volume before and after estimation may be compared and displayed. In this case, the measured value and the estimated value may be displayed in a form that can be recognized at a glance.

[0145] (Modification 15) In Modification 15, the ordering process of proposing a product different from the physiological product to the user based on the physiological information and making it orderable will be described.

[0146] For example, the control unit 270 selects a product suitable for the user (e.g., drugs, food products, cosmetics, supplements, etc.) based on the menstrual blood volume included in the physiological information, and makes a proposal by notifying the user.

[0147] When the menstrual blood volume is greater than a predetermined value, products containing iron (iron supplements, iron-containing supplements) are proposed. Specifically, based on the user's body information and menstrual blood volume, the required amount of iron is estimated, and the amount of the product corresponding to the required amount may also be notified. The required amount may be corrected according to the user's exercise amount.

[0148] It may be determined whether the preset value is exceeded by the menstrual blood volume, and if it is exceeded, a product containing iron is proposed. In addition to proposing a product containing iron, a menu that can be inoculated with iron may be proposed, and the food used in the menu may be made orderable in the ordering process.

[0149] Furthermore, the hormonal balance may decrease due to the menstrual blood volume. The decrease in hormonal balance can be a factor causing rough skin, color change, constipation, diarrhea, etc. Therefore, cosmetics, intestinal regulators, laxatives, antidiarrheals, etc. may be proposed. Furthermore, for users who want to know more about hormonal balance, videos or articles on information such as why it is necessary and how dangerous it is may be presented. Correct knowledge such as the reason for the necessity and risks can be given to the user.

[0150] In addition, evaluations or impressions of other users may be attached to the proposed products. In particular, if the evaluations or impressions of the same group as the user can be browsed, the evaluations or impressions of others similar to the user's situation can be grasped, which is more effective.

[0151] FIG. 31 is an explanatory diagram showing an example of an ordering screen according to Modification 15. As shown in FIG. 31, on the ordering screen, a menstrual blood volume display section R5 and four candidate sections R1 to R4 are arranged in the vertical direction. In the menstrual blood volume display section R5, the measured or estimated menstrual blood volume is displayed. In each of the candidate sections R1 to R4, ordering of different products is proposed.

[0152] Specifically, in the candidate section R1, the first symptom estimated from the menstrual blood volume (the possibility of iron deficiency) and the amount of iron deficiency are displayed. When the correction input button B71 is touched, the amount of iron deficiency becomes editable, and an editing operation from the user is accepted.

[0153] Below the correction input button B71, coping methods are proposed. In the example of FIG. 31, the iron supplement product A1 and the milk product A2 are proposed. Each product is provided with an evaluation of the same group and a comment display button B72. When the comment display button B72 is touched, the screen transitions to a screen showing the comments on the product.

[0154] In the candidate section R2, the second symptom estimated from the menstrual blood volume (rough skin is expected) is displayed, and products are proposed below it. In the example of FIG. 31, the cosmetic product A3 is proposed.

[0155] In the candidate section R3, the third symptom estimated from the menstrual blood volume (diarrhea is expected) is displayed, and products are proposed below it. In the example of FIG. 31, the intestinal regulator product A4 is proposed.

[0156] Some products may be provided with an evaluation of the same group and a comment display button B72. When the comment display button B72 is touched, the screen transitions to a screen showing the comments on the product. In addition, each product is provided with an order button B73. When the order button B73 is touched, the screen transitions to an order screen. Also, on the order screen, a monthly subscription system join button B74 is provided. When the monthly subscription system join button B74 is touched, the screen transitions to a monthly subscription system join screen.

[0157] In the candidate section R4, the fourth symptom estimated from the menstrual blood volume (hormonal imbalance) is displayed, and an explanation of the fourth symptom is displayed below it, and a video button B75 is provided. When the video button B75 is touched, the screen transitions to a video explaining the fourth symptom.

[0158] In this way, in the ordering process, products different from sanitary napkins are proposed to the user based on physiological information and can be ordered. Therefore, the user can easily order the proposed products. Since this product is proposed based on the user's own physiological information, it is also suitable for maintaining the user's physical condition.

[0159] (Modification Example 16) In Modification Example 16, the case where the user's menstrual blood volume and health information can be displayed will be described. In Modification Example 16, the stool volume and hormone balance are exemplified as health information, but other health information (such as blood pressure, urine volume, etc.) may also be used. The stool volume is the amount of stool excreted measured by the user during defecation. The method of measuring the stool volume can be any method. The hormone balance can be estimated from the correlation between the menstrual blood volume and / or stool volume by obtaining a relational expression in advance, and the hormone balance can be estimated from the menstrual blood volume, stool volume, and relational expression. Since the hormone balance includes estrogen and progesterone, it can be estimated by obtaining each relational expression in advance.

[0160] FIG. 32 is an example of a display example according to Modification Example 16. In FIG. 32, the menstrual blood volume, stool volume, and hormone balance are graphed and are listed and displayed on the information notification device 200. By the user visually recognizing this display, the relationship between the menstrual blood volume, stool volume, and hormone balance can be analyzed.

[0161] (Modification Example 17) In Modification Example 17, the case where the measuring device 100 can be shared with other users will be described. In this case, the measuring device 100 is installed in a facility outside the user's home (such as an office, a toilet in a store, etc.). As a result, the user can measure the menstrual blood volume even when outside. The user registers in the sharing service in advance and logs in to the sharing service by having the measuring device 100 outside the home read their own ID information. As a result, it becomes possible to transmit the measurement result by the measuring device 100 to the server device 300 of the sharing service.

[0162] When ordering napkins, it is also possible to have them delivered to a location other than your home (e.g., office, convenience store, drugstore, parcel locker). For example, if a sharing service has installed a napkin supply device together with the measuring device 100, the user can also pick up the ordered napkins from that supply device. In this case, since the user does not have to carry the napkins, they can go out more lightly. Without having to carry napkins, it becomes less likely for others to know about menstruation, reducing the user's mental burden.

[0163] Furthermore, the information notification device 200 possessed by the user may be notified of the pickup location. In this case, candidates for the pickup location may be overlaid and displayed on a map near the current location.

[0164] Furthermore, the toilet where the measuring device 100 compatible with the sharing service is installed may be overlaid and displayed on a map near the current location. In this case, the occupancy status of the toilet may also be notified.

[0165] These services are basically provided for a fee, but for example, the services may be provided free of charge or at a low price to users who have permitted data sharing. Furthermore, the services may be provided free of charge or at a low price to users who have viewed the advertisements displayed on the information notification device 200.

[0166] [Others] Although the embodiments have been described above, the present disclosure is not limited to the above embodiments. In addition, forms obtained by applying various modifications conceivable by those skilled in the art to each embodiment, or forms realized by arbitrarily combining the components and functions in each embodiment without departing from the spirit of the present disclosure are also included in the present disclosure.

[0167] In the above embodiment, the case of photographing napkins with the information notification device 200 has been exemplified, but napkins may be photographed with an imaging device other than the information notification device, and search information may be obtained from the image obtained by the photographing. For example, the measuring device may have an imaging unit.

[0168] Alternatively, an ID tag may be provided on the napkin or its package, and search information may be obtained by reading the information in the ID tag with an NFC-compatible device. The NFC-compatible device may be, for example, an information notification device, a measurement device, or a device separate from these.

[0169] The weight of the napkin before use may differ between the ideal value and the actually measured value. Therefore, for example, weight measurement may be performed for each lot at the time of shipping the napkins, and the weight of each napkin based on the measurement result may be registered in the database as the weight before use.

[0170] In the above embodiment, the case where the weight of menstrual blood is obtained by subtracting the weight of the napkin before use from the weight of the napkin after use acquired by the measuring device 100 is illustrated. However, the method for obtaining the weight of menstrual blood is not limited to this. For example, the weight of menstrual blood may be estimated from the weight of the napkin after use manually measured by the user, and the result may be input to the information notification device 200 to be obtained. Also, it is possible to estimate the weight of menstrual blood based on the area of menstrual blood adhering to the napkin after use. In this case, the user may visually recognize the area of menstrual blood, estimate the weight of menstrual blood in multiple steps (for example, 10 steps), and input the result to the information notification device 200 to be obtained. Or, the information notification device 200 may photograph the menstrual blood, and the information notification device 200 may estimate the weight of menstrual blood from the image to obtain it.
