Description

The disclosed embodiment relates to an excretion information management system.

Conventionally, toilet devices are known that automatically measure the shape (properties) and volume of feces (hereinafter also referred to as "stool") in the toilet in order to manage the health condition of the user (see, for example, Patent Document 1). Biological information such as information on urine, information on fecal gas, and information on blood flow, as well as information on stool such as the presence or absence of excretion and the properties of stool (color, shape, amount), are indicative of the health condition and are therefore said to be a barometer of health. Note that not only one biological information represents the health condition, but the stability of biological information over multiple days (for example, one month) is also related to the health condition.

Japanese Patent Application Publication No. 2018-146244

However, the above-mentioned conventional technology does not take into consideration the case where a user obtains biometric information at different locations, and it is not always possible to appropriately record and display biometric information obtained at multiple locations. .

The disclosed embodiments aim to provide a biometric information management system that appropriately records and displays biometric information acquired at different locations.

The biometric information management system according to one aspect of the embodiment is a biometric information management system that includes a detection unit that is installed on a toilet or a toilet seat installed on the toilet and detects a user's biometric information, a display unit that can communicate directly or indirectly with the detection unit and has a display function, an input means, a clock unit that acquires date and time information when the user's biometric information is detected, and a storage unit that automatically records a biometric record including the biometric information and the date and time information, and is characterized in that the input means is capable of inputting the biometric record obtained outside the toilet by adding it to the storage unit, and the display unit displays the biometric record recorded in the storage unit.

According to the biometric information management system according to one aspect of the embodiment, biometric information from a toilet seat device or toilet bowl capable of detecting a user's biometric information is automatically recorded in a storage unit, and biometric records obtained from devices other than the toilet seat device or toilet bowl can also be added and input to the storage unit, and the biometric records recorded in the storage unit are displayed. This allows the excretion information management system to properly record and display biometric information obtained from multiple toilet bowls. Here, when living an everyday life, there is not just one toilet to use. For example, even if a toilet is in a house, if a person goes out for a long time for school or work, he or she will excrete in a toilet at the destination. In other words, even if a toilet that is used daily (e.g., a toilet in a residence) has a function for automatically acquiring biometric records, data will be lost if another toilet is used. A health condition cannot be inferred from only one biometric record, but is inferred based on a biometric history over multiple days (e.g., one month). If there is a loss in the biometric history, the health condition cannot be correctly interpreted from the history data. For example, when the biological information is information about feces, irritable bowel syndrome (IBS) is diagnosed based on the frequency of constipation or diarrhea in a month (e.g. Rome III, etc.). Therefore, if there are many gaps in the biological history, it will be insufficient as a health management record. On the other hand, the biological information management system automatically acquires, for example, defecation and urination information as daily biological record data used for health management, records (accumulates) the data, and the user can view the recorded data on a display device. The biological information management system can add data acquired in other toilets and eliminate data gaps, so that more sufficient history data can be acquired and is useful for health management. Note that the biological information in this invention also includes biological processing information obtained based on the biological information.

In the biological information management system according to one aspect of the embodiment, the display section displays the biological records recorded in the storage section in chronological order.

According to the biometric information management system according to one aspect of the embodiment, biometric records are displayed in chronological order. Thereby, the biometric information management system can recognize biometric records in chronological order. For example, a biological information management system allows a user to check and interpret the daily trends and stability of excretion by displaying time-series data with no defects.

In the biometric information management system according to one aspect of the embodiment, the input means receives manual input of the biometric record obtained from a source other than the toilet.

According to the biological information management system according to one aspect of the embodiment, by accepting the input of biological records obtained using a toilet other than a manual toilet, for example, even defecation performed using a toilet without an automatic recording function can be registered as a biological record. can do. Thereby, the biometric information management system can appropriately record and display biometric information obtained from a plurality of toilet bowls. In this way, in a biological information management system, for example, if the biological information is information about stool, by manually recording the results of visual confirmation of the stool, the information on the excretion can be registered no matter where the body defecates. be able to. This information can be useful for health management because it can prevent defects in biological records.

In one embodiment of the biometric information management system, the storage unit assigns a first label to the automatically recorded biometric record, and assigns a second label to the biometric record input by the input means and stores the same.

According to the biometric information management system according to one aspect of the embodiment, by managing automatically recorded biometric records and manually input biometric records in a distinguishable manner, processing can be performed using automatically recorded biometric records and manually input biometric records. The aspects can be different. In this way, in a biological information management system, for example, when the biological information is information related to stool, visual data input (manual input) is more difficult to record the time and nature of excretion than information acquired in the toilet (automatic recording). Since there are likely to be variations in information, it will be easier to analyze past information if you can tell whether it was entered manually or automatically.

In one embodiment of the biometric information management system, if recording to the storage unit has not been performed for a predetermined period of time, a notification is issued to prompt input to the storage unit.

According to the biometric information management system according to one aspect of the embodiment, when recording to the storage unit is not performed for a predetermined period, a notification is issued to prompt input to the storage unit, thereby suppressing failure to register biometric records. can do. For example, the biometric information management system can prevent users from forgetting to input information when there is a high possibility that the user has forgotten to input the information even though they are using another toilet.

In the biological information management system according to one aspect of the embodiment, the predetermined period is calculated based on the date and time information recorded in the storage unit.

According to a biometric information management system according to one aspect of the embodiment, a predetermined period for determining the notification timing for prompting input to the storage unit is calculated from date and time information, and a notification can be issued to prompt manual input at an appropriate timing. For example, some people use the toilet more than twice a day, while others use the toilet once every three days. Thus, the biometric information management system prompts the user to input information at an appropriate timing that suits the user. In the biometric information management system, the user is prompted to input information, but because the prompting is done at an appropriate timing, the user can be prevented from forgetting to input information without feeling bothered.

In the biometric information management system according to one aspect of the embodiment, the biometric record is estimated from the biometric record recorded in the storage unit, and the biometric record is received manually from a location other than the toilet. First, the estimated biological record is input to the input means.

According to a biometric information management system according to one aspect of the embodiment, by inputting (displaying) the estimated information in advance to the input means, the user only needs to confirm the estimated information and correct any information that differs, which reduces the complexity of manual input and promotes manual input by the user. In this way, by inputting (displaying) the estimated information in advance to the input means before the user manually inputs the information, the user can easily register biometric records without the hassle of manual input.

In the biological information management system according to one aspect of the embodiment, the storage unit stores information on the position of the toilet bowl together with the biological record, and the display unit stores information on the position of the toilet bowl from which the biological record was acquired together with the biological record. Display the information shown.

According to a biometric information management system according to one aspect of the embodiment, by displaying the location information of the toilet where the biometric record was obtained along with the biometric record, it is possible to allow the user to check the biometric history taking into account the location where the biometric record was obtained. For example, when living a different lifestyle from everyday life, such as traveling, toilet usage habits can become disrupted. In other words, the location of the toilet used is an important parameter for managing toilet usage habits. Therefore, by displaying location information as well, the biometric information management system is useful for analyzing toilet usage habits, and ultimately for health management.

In one embodiment of the biological information management system, the biological information is at least one of information related to stool, information related to urine, information related to bowel movement gas, information related to blood flow, and information related to heart rate.

According to the biological information management system according to one aspect of the embodiment, at least one of information regarding feces, information regarding urine, information regarding defecation gas, information regarding blood flow, and information regarding heartbeat can be acquired as biological information. It can be useful for biological information management.

In a biological information management system according to one aspect of the embodiment, the biological information is at least two of the following information: information on stool, information on urine, information on bowel movement gas, information on blood flow, and information on heart rate. When at least one of the biological information is acquired and it is detected that at least one of the biological information has not been acquired, a display is performed on the display unit to prompt the user to input the biological information that has not been acquired.

According to a biometric information management system according to one aspect of the embodiment, when at least one piece of biometric information is acquired among a plurality of pieces of biometric information, and it is detected that at least one piece of biometric information has not been acquired, a display can be displayed on the display unit to prompt the user to input the biometric information that was not acquired, thereby more reliably preventing the user from missing out on inputting biometric information.

According to one aspect of the embodiment, biometric information performed at a plurality of toilet bowls can be appropriately recorded and displayed.

Below, an embodiment of the excretion information management system disclosed in the present application will be described in detail with reference to the attached drawings. Note that the present invention is not limited to the embodiment described below.

<1. Embodiment>
The biological information management system according to each embodiment described below will be described as an excretion information management system 1, as an example. The excretion information management system 1 manages excretion information (hereinafter also referred to as "excretion record") regarding the user's excretion based on information detected by a sensor. In the following example, a camera (two-dimensional image sensor) will be described as an example of the stool quality sensor 302 which is a detection unit (sensor). Note that any sensor can be used as the stool quality sensor 302 as long as it can detect at least one of the presence or absence of stool excretion, the color, shape, and amount of stool, but this point will be described later.

<1-1. Configuration of the Excretion Information Management System>
The configuration of the excretion information management system according to the embodiment will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a perspective view showing an example of the configuration inside a toilet room. Fig. 2 is a perspective view showing an example of the arrangement of sensors according to the embodiment. Fig. 3 is a diagram showing an example of the configuration of the excretion information management system according to the embodiment.

First, an example of the configuration of the toilet room R that is common to each embodiment of the excretion information management system 1 will be described using FIG. 1. Hereinafter, the configuration inside the toilet room R shown in FIGS. 1 and 2 may be collectively referred to as a toilet system TS. As shown in FIG. 1, in the toilet room R, a Western-style toilet bowl (hereinafter referred to as "toilet bowl") 7 is installed on the floor F. In addition, below, the direction facing into the space of the toilet room R from the floor surface F is described as the top. The toilet seat device 2 is provided above the toilet bowl 7.

The toilet bowl 7 is made of ceramic, for example. A bowl part 8 is formed in the toilet bowl 7. The bowl part 8 has a downwardly recessed shape and is a part that receives the user's excrement. Note that the toilet bowl 7 is not limited to the floor-standing type as shown in the figure, but may be of any type as long as the toilet system TS is applicable, and may be of a wall-mounted type or the like. The toilet bowl 7 is provided with a rim part 9 around the entire circumference of the end of the opening where the bowl part 8 faces. For example, the toilet room R may be provided with a wash water tank for storing wash water near the toilet bowl 7, or may be of a so-called tankless type in which no wash water tank is installed.

For example, when a user operates a flushing operation unit (not shown) provided in the toilet room R, a toilet flush is performed by supplying flush water to the bowl portion 8 of the toilet 7. The flushing operation unit may be an operation lever or a touch operation on a toilet flushing object displayed on the operation device 10. Note that the flushing operation unit is not limited to an operation lever or the like that allows the toilet to be flushed manually by the user, but may also be one that allows the toilet to be flushed by a sensor that detects the user, such as the seating sensor 301.

The toilet seat device 2 is attached to the top of the toilet bowl 7 and includes a main body 3, a toilet lid 4, a toilet seat 5, and a cleaning nozzle 6. The toilet seat device 2 is placed on top of a toilet bowl 7 in which a bowl portion 8 for receiving excrement is formed. The toilet seat device 2 is placed on the top of the toilet bowl 7 so that the cleaning nozzle 6 advances into the bowl portion 8 before spraying cleaning water. Note that the toilet seat device 2 may be detachably attached to the toilet bowl 7, or may be attached so as to be integrated with the toilet bowl 7.

As shown in FIG. 1, the toilet seat 5 is formed in a ring shape with an opening 50 in the center, and is positioned along the rim portion 9 so that it overlaps with the opening of the toilet bowl 7. A user sits on the toilet seat 5. The toilet seat 5 functions as a seating portion that supports the buttocks of the seated user. Also, as shown in FIG. 1, the toilet lid 4 and toilet seat 5 are each pivotally supported at one end by the main body portion 3, and are attached so that they can rotate (be opened and closed) around the pivot portion of the main body portion 3. The toilet lid 4 is attached to the toilet seat device 2 as necessary, and the toilet seat device 2 does not have to have a toilet lid 4.

The cleaning nozzle 6 is a nozzle for discharging water for cleaning. The cleaning nozzle 6 is capable of spraying cleaning water. The cleaning nozzle 6 is capable of spraying cleaning water toward the user. The cleaning nozzle 6 is a nozzle for cleaning the private parts. The cleaning nozzle 6 is configured to be movable forward and backward relative to the main body cover 30, which is the housing of the main body 3, by driving a driving source such as an electric motor (such as the nozzle motor 61 in FIG. 4). The cleaning nozzle 6 is also connected to a water source such as a water pipe (not shown). Then, when the cleaning nozzle 6 is in a position advanced relative to the main body cover 30, which is the housing of the main body 3, as shown in FIG. 1 (hereinafter also referred to as the "advanced position"), it sprays water from the water source onto the user's body to clean the private parts.

FIG. 1 shows a state in which the cleaning nozzle 6 is in the advanced position. Note that the cleaning nozzle 6 may also be used for cleaning the inside of the toilet bowl 7 (bowl portion 8, etc.). The cleaning nozzle 6 may be used to be able to switch between a private part cleaning mode in which the user's private parts are cleaned and a toilet bowl cleaning mode in which water is sprinkled into the toilet bowl 7. For example, the cleaning nozzle 6 may be used to be able to switch between a private part cleaning mode and a toilet bowl cleaning mode according to control by the control unit 23 (see FIG. 4) of the toilet seat device 2.

The operating device 10 is provided in the toilet room R. The operating device 10 is provided at a position where the user can operate it. The operating device 10 is provided at a position where the user can operate it when sitting on the toilet seat 5. In the example shown in FIG. 1, the operating device 10 is arranged on the wall surface W on the right side when viewed from the user seated on the toilet seat 5. Note that the operating device 10 is not limited to the wall surface, and may be arranged in various ways as long as it can be used by a user seated on the toilet seat 5. For example, the operating device 10 may be provided integrally with the toilet seat device 2.

Here, an example of sensor arrangement will be described with reference to FIG. 2. In FIG. 2, the toilet seat 5 is raised to show the arrangement of the sensor, excluding the toilet lid 4, and to illustrate the back surface 51 of the toilet seat 5, which is the surface opposite to the surface on which the user sits (seating surface). FIG.

Figure 2 shows the cleaning nozzle 6 (see Figure 1) in a position where it is stored inside the main body cover 30 (hereinafter also referred to as the "storage position"). As shown in Figure 2, when the cleaning nozzle 6 is in the storage position, the nozzle lid 60 is closed and the cleaning nozzle 6 is hidden behind the nozzle lid 60. When cleaning is performed using the cleaning nozzle 6, the nozzle lid 60 opens and the cleaning nozzle 6 protrudes from the opening in the main body cover 30 (the opening covered by the nozzle lid 60 in the closed state in Figure 2), and the cleaning nozzle 6 transitions to an advanced state.

As shown in FIG. 2, the seating sensor 301 and the stool condition sensor 302, which are sensors used in the excretion information management system 1, are arranged on the back surface 51 side of the toilet seat 5. The seating sensor 301 may be detachable from the back surface 51 of the toilet seat 5, or may be fixed to the back surface 51 of the toilet seat 5. The seating sensor 301 may be included in the configuration of the toilet seat device 2. In addition, the stool condition sensor 302 may be detachable from the back surface 51 of the toilet seat 5, or may be fixed to the back surface 51 of the toilet seat 5. The stool condition sensor 302 may be included in the configuration of the toilet seat device 2.

In addition, the seat sensor 301 may be of any detection type and may be placed in any location as long as it can detect a user sitting on the toilet seat 5. For example, if the seat sensor 301 is an infrared or μ (microwave) wave distance sensor that detects sitting by distance, the seat sensor 301 may be placed in a position that detects a person's feet from the side of the toilet bowl 7 or in a position that detects a person's back from a tank attached to the toilet bowl 7. For example, if the seat sensor 301 detects a person's feet from the side of the toilet bowl 7, the seat sensor 301 may be placed near the outer periphery of the toilet bowl 7 shown in FIG. 2. For example, if the seat sensor 301 detects a person's back from a tank attached to the toilet bowl 7, the seat sensor 301 may be placed on the outer periphery of the tank provided at the rear of the toilet bowl 7 shown in FIG. 2. For example, if the seat sensor 301 is a distance sensor that detects sitting by distance, the seat sensor 301 may be placed around the toilet bowl 7. For example, if the seating sensor 301 detects sitting by distance, it may be placed on the ceiling of the toilet room R. Or, for example, if the seating sensor 301 is a contact switch and detects the sinking of the toilet seat due to sitting, the seating sensor 301 may be placed on the pivot support part of the toilet seat 5. Or, for example, if the seating sensor 301 is a load sensor and detects sitting by the weight on the toilet seat, the seating sensor 301 may be placed on the underside of the toilet seat 5, on the surface that comes into contact with the toilet bowl 7. Also, the stool condition sensor 302 may be placed anywhere as long as it is possible to detect stool excreted in the toilet bowl 7.

As shown in FIG. 3, the excretion information management system 1 includes a toilet system TS including a toilet seat device 2, an operating device 10, a seating sensor 301, and a stool property sensor 302, a user terminal 200, and a server device 400. The excretion information management system 1 may include multiple toilet systems TS, multiple user terminals 200, and server devices 400. The case where multiple toilet systems TS are included will be described later.

The toilet seat device 2 is a device placed in the toilet room R. The toilet seat device 2 communicates with each device of the toilet system TS (the operating device 10, the seating sensor 301, and the stool quality sensor 302), the user terminal 200, and the server device 400.

The toilet seat device 2 performs a process (personal identification) for acquiring information for identifying a user who uses the toilet bowl 7 in the toilet room R to defecate. For example, the toilet seat device 2 acquires information for identifying the user who uses the toilet bowl 7 to defecate through communication with the user terminal 200 owned by the user, the user's operation on the operating device 10, etc. and identify the user. For example, the toilet seat device 2 communicates with a user terminal 200 owned by a user, and receives user identification information (user ID, etc.) for identifying the user from the user terminal 200. Note that the toilet seat device 2 may use any method to identify the user as long as it is possible to identify the user who uses the toilet bowl 7 in the toilet room R to defecate.

Further, the toilet seat device 2 manages the acquired user identification information and the excretion information (defecation information) regarding the detected excretion (defecation) in association with each other. For example, the toilet seat device 2 associates the acquired user identification information and excretion information (defecation information) and transmits them to the server device 400. The server device 400 associates the received user identification information with the received excretion information and registers it in the storage unit 420. Further, the toilet seat device 2 may associate user identification information and excretion information (defecation information) with toilet seat identification information (toilet seat identification information) for identifying the toilet seat device 2, and transmit the association to the server device 400. In this case, the server device 400 registers the received user identification information in the storage unit 420 in association with information indicating the location (for example, home, school, etc.) corresponding to the received excretion information and toilet seat identification information. Further, the toilet seat device 2 may associate user identification information and excretion information (defecation information) with information indicating the arrangement position of the toilet seat device 2 (position information), and transmit the information to the server device 400. In this case, the server device 400 associates the received user identification information with the received excretion information and position information and registers them in the storage unit 420. Note that details such as the configuration of the toilet seat device 2 will be described later.

Further, the operating device 10 may include switches and buttons, and may accept various operations using the switches and buttons. The display screen 11 is a display screen of a tablet terminal or the like realized by, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display, and is a display device for displaying various information. That is, the operating device 10 receives input from the user through the display screen 11 and also outputs to the user. The display screen 11 is a display device that displays various information.

The operation device 10 accepts a user's operation to stop control being performed by the toilet seat device 2. The operation device 10 accepts a user's operation to start the execution of local washing by the toilet seat device 2. The operation device 10 accepts an instruction from the user to the washing nozzle 6. The operation device 10 accepts a user's operation to cause the toilet seat device 2 to output a predetermined sound. The operation device 10 accepts a user's operation to perform a sterilization process to sterilize the washing nozzle 6 (see FIG. 1) of the toilet seat device 2 with disinfectant water. The operation device 10 accepts a user's operation to adjust the force of the water discharged during local washing by the toilet seat device 2. The operation device 10 accepts a user's operation to adjust the volume of the sound output by the toilet seat device 2. The operation device 10 accepts a user's operation to select a language when information regarding toilet use is displayed on the operation device 10 or output as audio.

For example, the operation device 10 may display an object that accepts the above-mentioned user's operation on the display screen 11, and execute various processes in response to the user's touch on the displayed object. For example, the operation device 10 may have a switch, button, etc. that accepts the above-mentioned user's operation, and execute various processes in response to the user's touch on the switch, button, etc. Note that the above is an example, and the operation device 10 may accept a user's operation to execute various processes.

The seating sensor 301 has the function of detecting a person sitting on the toilet seat device 2. The seating sensor 301 detects when a user sits (takes a seat) on the toilet bowl 7. The seating sensor 301 can detect when the user sits on the toilet seat 5. The seating sensor 301 also functions as a seating-off detection sensor that detects when the user leaves the toilet seat 5. The seating sensor 301 detects when the user is seated on the toilet seat 5.

The seating sensor 301 is a switch that switches ON/OFF depending on, for example, the weight of a user sitting on the toilet seat 5. When the user sits down and the toilet seat 5 sinks, the seating sensor 301 turns on, thereby detecting that the user has sat on the toilet bowl 7.

Note that the above is an example, and the seating sensor 301 is not limited to the above, and may detect whether a person is sitting on the toilet seat device 2 by various means. The seating sensor 301 transmits a seating detection signal to the toilet seat device 2.

The seating sensor 301 is communicably connected to the toilet seat device 2 via a predetermined network, either by wire or wirelessly. For example, the seating sensor 301 may be communicably connected to the toilet seat device 2 using a predetermined wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). Note that the toilet seat device 2 and the seating sensor 301 may be connected in any manner as long as they can transmit and receive information, and may be connected communicably by wire or may be communicably connected wirelessly. You can. For example, the seating sensor 301 may be communicably connected to the toilet seat device 2 via the network N by wire or wirelessly.

The stool quality sensor 302 functions as a detection unit that detects defecation by capturing an image of the inside of the toilet bowl 7. The stool quality sensor 302 is a camera that captures images, and generates a two-dimensional image. For example, the stool condition sensor 302 includes an area sensor (two-dimensional image sensor) in which a CCD (Charge Coupled Device) sensor or a CMOS (Complementary Metal Oxide Semiconductor) sensor is arranged in a planar (two-dimensional) manner.

The stool property sensor 302 photographs the water seal part of the toilet bowl 7 (for example, the part where the water seal part of the bowl part 8 accumulates). The stool property sensor 302 is arranged on the back surface 51 of the toilet seat 5 in a position and orientation that allows it to detect (image) the water seal part of the toilet bowl 7. For example, the stool property sensor 302 is provided on the toilet seat 5 with its directionality directed toward the water seal part of the toilet bowl 7 when the toilet seat 5 is lowered (when the user is seated on the toilet seat 5 and can defecate). The stool property sensor 302 may be arranged in any manner as long as it can detect (image) the water seal part of the toilet bowl 7. The stool property sensor 302 may be arranged in any manner as long as it can image the water seal part of the toilet bowl 7. The stool property sensor 302 may also take still images or may also take moving images. The stool property sensor 302 may also be arranged to image (detect) stool as it falls. Also, if the inside of the toilet becomes dark when the user sits on the toilet seat and it is not possible to take a picture with sufficient brightness, a light source (light-emitting unit) may be provided.

The stool property sensor 302 is connected to the toilet seat device 2 via a specified network so as to be able to communicate with it wired or wirelessly. For example, the stool property sensor 302 may be connected to the toilet seat device 2 so as to be able to communicate with it by a specified wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). Note that the toilet seat device 2 and the stool property sensor 302 may be connected in any manner as long as they are able to send and receive information, and may be connected to each other so as to be able to communicate with each other wired or wirelessly. For example, the stool property sensor 302 may be connected to the toilet seat device 2 via a network N so as to be able to communicate with each other wired or wirelessly.

Note that the stool quality sensor 302 is not limited to an area sensor (two-dimensional image sensor) that captures a two-dimensional image, as long as it can detect at least one of the presence or absence of stool excretion, the color, shape, and amount of stool. , various sensors may be used. For example, the stool quality sensor 302 may be a water level sensor. In this case, the stool quality sensor 302 detects defecation by detecting a change in the water level in the water sealing part of the toilet bowl 7. Furthermore, the stool quality sensor 302 may be a radiation thermometer. In this case, the stool quality sensor 302 detects defecation by receiving infrared rays emitted from defecation and detecting the radiant temperature.

For example, the stool property sensor 302 may be a line sensor that captures one-dimensional images. In this case, the toilet seat device 2 may capture images of the falling stool over time using the stool property sensor 302, generate two-dimensional images from the one-dimensional images captured by the stool property sensor 302, and perform image processing based on the generated two-dimensional images. For example, the stool property sensor 302 may be an ultrasonic sensor. In this case, the stool property sensor 302 detects defecation by emitting ultrasonic waves to the defecation and receiving waves (ultrasound) reflected from the defecation. The stool property sensor 302 may include multiple sensors described above. For example, the stool property sensor 302 may include a camera and a radiation thermometer, and when defecation is detected by the radiation thermometer, the camera may capture a two-dimensional image. Note that the above is merely one example, and the stool property sensor 302 may have any configuration as long as it can detect at least one of the presence or absence of defecation, the color, shape, and amount of the stool.

The user terminal 200 functions as a display unit (display device) that displays various information (excretion information) related to the user's excretion, such as excretion records. The user terminal 200 receives information indicating the excretion record from the toilet seat device 2, and displays the received information indicating the excretion record. For example, the user terminal 200 displays the excretion record in chronological order by the date and time of excretion.

For example, the user terminal 200 is a user terminal (computer) used by a user. The user terminal 200 is realized by, for example, a smartphone, a mobile phone, a PDA (Personal Digital Assistant), a tablet terminal, a notebook PC (Personal Computer), etc. For example, the user terminal 200 is connected to the toilet seat device 2 via a network N so as to be able to communicate with each other via a wired or wireless connection. For example, the user terminal 200 may be connected to the toilet seat device 2 so as to be able to communicate with each other via a specified wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark).

The user terminal 200 transmits and receives information between the toilet seat device 2 and the server device 400. For example, the user terminal 200 receives information related to the user's excretion from the server device 400 and displays the received information. For example, the user terminal 200 receives content indicating the user's excretion record from the server device 400 and displays the received content.

The user terminal 200 may also have a sensor (position sensor) that detects the position of the user terminal 200. For example, the user terminal 200 may have a GPS (Global Positioning System) sensor and detect the position of the user terminal 200 (user). For example, the user terminal 200 may acquire information on the excretion location using the GPS function. The user terminal 200 may also acquire position information of the base station with which it is communicating, or position information of the user terminal 200 (user) estimated using WiFi (registered trademark) (Wireless Fidelity) radio waves.

The user terminal 200 accepts input of an excretion record of excretion in a toilet bowl other than the toilet bowl 7 of the toilet system TS. The user terminal 200 accepts manual input of a record of excretion using a toilet bowl other than the toilet bowl. The user terminal 200 displays the excretion record recorded in the defecation information database 421 of the server device 400. The user terminal 200 displays the excretion record in chronological order. The user terminal 200 displays information indicating the position of the toilet bowl where the user defecated along with the excretion record.

The server device 400 associates the received user identification information with the received excretion information and registers it in the storage unit 420. In addition, when the received excretion information is automatic storage detected by the toilet seat device 2 of the toilet system TS, the server device 400 handles the received excretion information with information (first label) indicating that it is automatic recording. and register it in the storage unit 420. Further, when the received excretion information is manually input by the user, the server device 400 registers the received excretion information in association with information indicating manual input (second label) in the storage unit 420. do.

The server device 400 is connected to the toilet seat device 2 and the user terminal 200 via a predetermined network (network N) such as the Internet, so as to be able to communicate with them in a wired or wireless manner. Note that the server device 400 may be connected to the toilet seat device 2 and the user terminal 200 in any manner as long as it is possible to send and receive information, and may be connected to them in a wired or wireless manner so as to be able to communicate with them.

Any configuration and arrangement of the server device 400 can be adopted as long as it can communicate with the toilet seat device 2 and the user terminal 200 and perform processing. For example, the server device 400 may be a mobile terminal (device) such as a notebook computer that can be carried by the administrator of the excretion information management system 1 or the like. Further, the server device 400 may be placed inside the toilet room R.

Note that the above is just an example, and the excretion information management system 1 can adopt any device configuration as long as it can realize the desired processing. For example, if the user terminal 200 has the function of the server device 400, the excretion information management system 1 does not need to have the server device 400. In this case, the user terminal 200 also functions as a recording unit (storage device) that manages defecation records and generates information to be displayed. In this case, the user terminal 200 communicates with the toilet seat device 2 and acquires the user's excretion information from the toilet seat device 2. For example, the user terminal 200 stores the user's excretion information acquired from the toilet seat device 2 in its own storage unit (corresponding to the storage unit 420 of the server device 400), and manages it as the user's excretion record.

For example, the operating device 10 may function as a display unit that displays the excretion record. Both the operating device 10 and the user terminal 200 may be included in the excretion information management system 1 as devices that function as display units. Sensors (detection units) such as the stool property sensor 302 included in the excretion information management system 1 may be included in the toilet seat device 2. Note that the above system configuration is merely an example, and the excretion information management system 1 may have any system configuration as long as the desired processing is possible.

Further, the excretion information management system 1 may also include sensors other than the seating sensor 301 and the stool quality sensor 302. For example, the excretion information management system 1 may include a human body detection sensor. The human body detection sensor has a function of detecting a human body. For example, the human body detection sensor is realized by a pyroelectric sensor using an infrared signal. For example, the human body detection sensor may be realized by a μ (microwave) sensor or the like. Note that the above is an example, and the human body detection sensor is not limited to the above, and may detect a human body by various means. For example, the human body detection sensor detects a person (such as a user) who has entered the toilet room R (see FIG. 1). The human body detection sensor transmits a detection signal to the toilet seat device 2.

For example, it stores various judgment models used to judge the shape, color, amount, etc. of stool. The memory unit 22 stores information related to the measured time. The memory unit 22 stores information indicating the time required for defecation. Note that the above is merely an example, and the memory unit 22 stores various information related to stool.

The control unit 23 may be a control device that controls various configurations and processes, for example. The control unit 23 is configured such that a program stored inside the toilet seat device 2 (for example, a program for determining stool engagement properties, etc. in the present disclosure) is stored in a RAM or the like by, for example, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). This is achieved by executing this as a work area. Further, the control unit 23 is realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 4, the control unit 23 has an acquisition unit 231, a clock unit 232, and a request unit 233, and realizes or executes the functions and actions of the information processing described below.

The clock unit 232 acquires the time related to defecation. The clock unit 232 acquires the date and time when the act of excretion was performed. The clock unit 232 acquires information indicating the date and time of excretion (date and time information). The clock unit 232 generates excretion information based on information detected by the sensor. The clock unit 232 transmits information to the server device 400 via the communication unit 21. For example, the clock unit 232 transmits excretion information of a user who uses the toilet seat device 2 to the server device 400.

Clock section 232 detects the time. The clock unit 232 measures the time when the seating sensor 301 detects that the user is sitting. The clock unit 232 measures the time when the stool quality sensor 302 first detects the acquired stool. The clock unit 232 acquires an excretion record consisting of the difference between the time when the sitting sensor 301 detects that the user is sitting and the time when the stool quality sensor 302 first detects stool. The clock unit 232 measures the time required for defecation in chronological order for each date and time of defecation. The clock unit 232 measures defecation over time based on detection by the stool quality sensor 302.

The clock unit 232 functions as a determination unit that performs various determination processes. The clock unit 232 performs determination processing using the information detected by the stool quality sensor 302. The clock unit 232 uses the information stored in the storage unit 22 to perform determination processing. The clock unit 232 determines whether stool is included in the image captured by the stool quality sensor 302. The clock unit 232 uses technology related to image recognition to determine whether feces is included in the image.

For example, the clock unit 232 uses an image as input and a model (feces determination model) that outputs information (score) indicating whether or not feces is included in the input image to determine whether or not feces is included in the image. In this case, the clock unit 232 compares the score output by the feces determination model to which the image is input with a threshold value (first threshold value), and determines that the image contains feces if the score is equal to or greater than the first threshold value. The clock unit 232 also compares the score output by the feces determination model to which the image is input with the first threshold value, and determines that the image does not contain feces if the score is less than the first threshold value. Note that the above is merely one example, and the clock unit 232 may determine whether or not feces is included in the image by appropriately using various information.

The clock unit 232 also determines the amount of stool based on the image captured by the stool property sensor 302. For example, the clock unit 232 determines the amount of stool based on the proportion of stool in the image. For example, the clock unit 232 may determine the amount of stool using a score output by a stool determination model. If the score output by the stool determination model to which an image is input is equal to or greater than a first threshold and less than a second threshold, the clock unit 232 may determine the amount of stool to be "very small." The second threshold is assumed to be a value greater than the first threshold. The clock unit 232 also may determine the amount of stool to be "small" if the score output by the stool determination model to which an image is input is equal to or greater than a second threshold and less than a third threshold. The third threshold is assumed to be a value greater than the second threshold.

Further, the clock unit 232 may determine the amount of stool to be "medium" or "standard" if the score output by the stool determination model into which the image is input is greater than or equal to the third threshold and less than the fourth threshold. . The fourth threshold value is assumed to be a larger value than the third threshold value. Further, the clock unit 232 may determine that the amount of stool is "large" when the score output by the stool determination model into which the image is input is greater than or equal to the fourth threshold and less than the fifth threshold. It is assumed that the fifth threshold value is larger than the fourth threshold value. Further, the clock unit 232 may determine that the amount of stool is "very large" when the score output by the stool determination model into which the image is input is equal to or higher than the fifth threshold. Note that the above five-stage determination is only an example, and the clock unit 232 may determine the amount of stool by appropriately using various information.

The clock unit 232 determines the properties of the stool from the detection results by the sensor. The clock unit 232 determines the properties of the user's stool by appropriately using various technologies that detect stool properties using optical methods. The clock unit 232 determines the properties of the stool corresponding to the stool image based on the stool image. For example, the clock unit 232 uses the stool image to determine the shape (also simply called "shape") of the stool corresponding to the stool image. The clock unit 232 uses the stool image to determine whether the shape of the stool corresponding to the stool image is one of multiple levels based on shape. For example, the clock unit 232 uses the stool image to determine whether the shape of the stool corresponding to the stool image is one of the following: hard, hard, cracked, banana-shaped, soft, muddy, or watery.

The clock unit 232 determines the shape of the stool from the detection results of the stool property sensor 302. The clock unit 232 determines the shape of the user's stool by appropriately using various techniques for detecting the shape of the stool using optical methods. The clock unit 232 determines whether the shape of the stool is round, hard, cracked, banana-shaped, soft, muddy, or watery by appropriately using various techniques for classifying the shape of the stool. For example, the clock unit 232 may determine (judge) the shape of the stool based on various information (feature quantities) such as the length of the stool image in the falling direction and the number of stool pieces (lumps).

The clock unit 232 may determine the shape of the stool using technology related to AI (artificial intelligence). For example, the clock unit 232 may determine the shape of stool using a learning model (shape determination model) generated by machine learning. In this case, the shape determination model is trained in advance using teacher data indicating classification determination. This training data includes a stool image and a label (correct answer information) indicating the shape of the lump (feces) contained in the stool image (rolly, crunchy, cracked, banana-shaped, soft, muddy, or watery). ) including multiple combinations. For example, a shape determination model is a model that receives a stool image as input and outputs information indicating the shape of a lump (feces) included in the input stool image. For example, the shape determination model is trained to output information on a label (shape of stool) corresponding to the input stool image when a stool image is input. Learning of the shape determination model is performed using various methods related to so-called supervised learning as appropriate. In this case, the shape determination model may be stored in the storage unit 22, and the clock unit 232 may determine the shape of the stool using the shape determination model stored in the storage unit 22. For example, the toilet seat device 2 may perform a learning process to generate a shape determination model. Note that the above is just an example, and the clock unit 232 may determine the shape of the stool using various information as appropriate. Furthermore, the seven stages of rolling, ticking, cracked, banana-like, soft, mud-like, and water-like described above are only examples of shapes, and the clock section 232 may determine other shapes. It may be determined to be lower than the level. In addition, although we have shown an example of determining whether the shape of stool is in one of multiple levels, this is not the case; if multiple shapes of stool are included in one excretion act, A plurality of stool shapes may be determined.

For example, the clock unit 232 uses a stool image to determine the color of the stool corresponding to the stool image. The clock unit 232 uses the stool image to determine whether the color of the stool corresponding to the stool image is one of multiple color-based levels. For example, the clock unit 232 uses the stool image to determine whether the color of the stool corresponding to the stool image is one of yellow, light ochre, ochre, brown, dark brown, and dark dark brown.

The clock unit 232 determines the color of the stool from the detection results of the stool property sensor 302. The clock unit 232 determines the color of the user's stool by appropriately using various technologies that detect stool color using optical methods. The clock unit 232 determines whether the color of the stool is yellow, light ochre, ochre, brown, dark brown, or dark brown by appropriately using various technologies related to classifying stool color. For example, the clock unit 232 determines (judges) the color of the stool based on various information (feature values) such as the brightness and lightness of the color image (RGB).

The clock unit 232 may determine the color of stool using technology related to AI (artificial intelligence). For example, the clock unit 232 may determine the color of stool using a learning model (color determination model) generated by machine learning. In this case, the color judgment model is trained in advance using teacher data indicating classification judgments. This training data includes a stool image and a label (correct answer information) indicating the color of the lump (feces) contained in the stool image (yellow, light ocher, ocher, brown, dark brown, or deep dark brown). Includes multiple combinations. For example, a color determination model is a model that receives a stool image as input and outputs information indicating the color of a lump (feces) included in the input stool image. For example, the color determination model is trained to output information on a label (color of stool) corresponding to the input stool image when a stool image is input. Learning of the color determination model is performed using various methods related to so-called supervised learning as appropriate. In this case, the color determination model is stored in the storage unit 22, and the clock unit 232 may determine the color of the stool using the color determination model stored in the storage unit 22. For example, the toilet seat device 2 may perform a learning process to generate a color determination model. Note that the above is just an example, and the clock unit 232 may determine the color of stool using various information as appropriate. Further, the six levels of yellow, light ocher, ocher, brown, dark brown, and deep dark brown described above are only examples of colors, and the clock portion 232 may determine other shapes or five levels. The determination may be made as follows. In addition, although we have shown an example of determining whether the color of stool is in one of multiple stages, this is not limited to this, and if multiple colors of stool are included in one excretion act, multiple colors may be used. The color of the stool may also be determined. Note that the various determination processes described above may be performed by the server device 400. In this case, the server device 400 has the information used for the determination process and the function of the determination process described above, and the toilet seat device 2 transmits the information detected by the stool quality sensor 302 to the server device 400.

The request unit 233 requests the server device 400 to register the detected user's excretion information. The requesting unit 233 requests the server device 400 to register the excretion information by transmitting the excretion information to the server device 400 via the communication unit 21 . The request unit 233 transmits the excretion information together with the user identification information to the server device 400, thereby causing the server device 400 to register the excretion information as information of the user specified by the user identification information. request.

<1-3. Functional configuration of server device>
Next, the functional configuration of the server device will be described with reference to Fig. 5. Fig. 5 is a block diagram showing an example of the configuration of the server device according to the embodiment. Specifically, Fig. 5 is a block diagram showing an example of the configuration of a server device 400, which is an example of a server device.

As shown in FIG. 5, the server device 400 has a communication unit 410, a storage unit 420, and a control unit 430. The server device 400 may also have an input unit (e.g., a keyboard, a mouse, etc.) that accepts various operations from an administrator of the server device 400, and a display unit (e.g., a liquid crystal display, etc.) that displays various information.

The communication unit 410 is realized by, for example, a communication circuit. The communication unit 410 is connected to the network N (see FIG. 3) by wire or wirelessly, and transmits and receives information to and from an external information processing device. For example, the communication unit 410 transmits and receives information to and from the toilet seat device 2, the user terminal 200, and the like. For example, the communication unit 410 transmits information (content) indicating excretion records to the user terminal 200.

The storage unit 420 is realized by, for example, a semiconductor memory device such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 420 is a computer-readable recording medium that non-temporarily records data used by a management program that manages excretion information and a generation program that generates information such as content to be provided. The storage unit 420 according to the embodiment includes a defecation information database 421, as shown in FIG. Note that the storage unit 420 stores not only the defecation information database 421 but also various information.

The defecation information database according to the embodiment stores various information regarding defecation of the user. For example, the defecation information database stores the user's defecation history. FIG. 6 is a diagram illustrating an example of the defecation information database according to the embodiment. The defecation information database shown in FIG. 6 includes items such as "date", "time", "label", "place", "shape", "color", and "amount".

"Date" indicates the date (day) on which the excretory act took place. "Time" indicates the time (hour) on which the excretory act took place.

“Label” indicates the type of excretion information acquisition mode. For example, "automatic" is the first label indicating that the excretion information was automatically detected, and indicates that the excretion information was automatically detected by the toilet seat device 2. Moreover, "manual" is a second label indicating that the excretion information was manually input by the user, and indicates that the excretion information was input by the user who performed the excretion act. In this way, the data detected by the detection unit (sensor) is recorded with an automatically recorded data label (first label) attached thereto. On the other hand, manually input data is recorded with a label (second label) of manually recorded data.

“Place” indicates the place where the act of excretion corresponding to the excretion information was performed. In addition, in the example of FIG. 6, information indicating the relationship between the user and the location, such as home or school, is registered as the "location", but the "location" is the specific latitude and longitude (latitude and longitude information). ), information indicating the area, name of the building where the act of defecation took place, etc. may be various types of information related to the place (position).

"Shape" indicates the shape of the obtained stool. For "shape", classification results are registered into a plurality of shapes, such as "rolling", "ticky", "cracked", "banana-like", "soft", "muddy", and "water-like". Note that the above is just an example, and the "shape" is not limited to the above, and information indicating various shapes may be registered.

"Color" indicates the color of the obtained stool. For example, "color" is registered as a classification into multiple colors such as "yellow," "light ocher," "ocher," "brown," "dark brown," and "dark brown." For example, the colors are darker in the order of "yellow," "light ocher," "ocher," "brown," "dark brown," and "dark brown," with "dark brown" being the darkest color. Note that the above is merely an example, and "color" is not limited to the above, and information indicating various colors may be registered.

"Amount" indicates the amount of stool obtained. For example, for "amount", classification results into multiple colors such as "very large", "large", "medium", "small", and "very small" are registered. For example, the amount decreases in the order of "very large," "large," "medium," "small," and "very small," with "very small" being the smallest stool. Note that the above is just an example, and the "amount" is not limited to the above, and information indicating various amounts may be registered.

In the example in Figure 6, the excretion information for the act of excretion performed at 7:15 on January 5th, and the information for the act of excretion performed at 7:30 on January 7th, etc. are registered. Indicates the condition. Note that, for the sake of explanation, FIG. 6 shows a state in which excretion information of one user (hereinafter referred to as "user U") is registered, but when managing excretion information of multiple users, Identification information for identifying the user (user identification information) is registered in association with each piece of excretion information.

For example, the excretion information for an act of excretion performed at 7:30 on January 7th indicates that it was automatically registered. That is, the excretion information for the act of excretion performed at 7:30 on January 7th is the excretion information detected by the toilet seat device 2. Additionally, the location where the act of defecating at 7:30 on January 7th was performed indicates that it took place at home. Furthermore, the nature of the stool that was excreted at 7:30 on January 7th was banana-shaped, dark brown in color, and small in quantity.

For example, the excretion information of the excretion act that took place at 7:15 on January 5th indicates that it was manually registered. In other words, the excretion information of the excretion act that took place at 7:15 on January 5th indicates that it was excretion information entered by user U. In addition, it indicates that the location of the excretion act that took place at 7:15 on January 5th was school. In addition, it indicates that the characteristics of the stool from the excretion act that took place at 7:15 on January 5th were banana-shaped, yellow-brown in color, and a large amount.

The defecation information database 121 may store various information according to the purpose, not limited to the above. As described above, the defecation information database 121 in FIG. 6 stores the defecation information of multiple users. For example, the defecation information database 421 may store a stool image as the defecation information. The defecation information database 421 stores information about the stool corresponding to the stool image in association with the stool image. The defecation information database 421 stores the judgment result (shape, color, amount, etc.) judged about the stool corresponding to the stool image in association with the stool image. The defecation information database 421 stores information such as the properties of the stool corresponding to the stool image and the amount of the stool corresponding to the stool image. The defecation information database 421 may also store the date and time when the stool image was acquired, information identifying the user who excreted the stool corresponding to the stool image, etc. in association with the stool image.

The control unit 430 is realized by, for example, executing a program (for example, a management program, a generation program, etc. according to the present disclosure) stored inside the server device 400 by a CPU, a GPU, or the like using a RAM or the like as a work area. Ru. Further, the control unit 430 is realized by, for example, an integrated circuit such as an ASIC or an FPGA.

As shown in FIG. 5, the control unit 430 includes a reception unit 431, a registration unit 432, and a provision unit 433, and implements or executes information processing functions and operations described below. Note that the internal configuration of the control unit 430 is not limited to the configuration shown in FIG. 5, and may be any other configuration as long as it performs information processing to be described later.

The reception unit 431 receives information. The reception unit 431 receives information to be stored in the storage unit 420. The reception unit 431 receives information manually input by the user. The reception unit 431 receives information input by the user by operating the user terminal 200. The reception unit 431 receives input of excretion records to be added and registered in the defecation information database 421. The reception unit 431 receives input of an excretion record of excretion using a toilet other than the toilet bowl 7 of the toilet system TS. The reception unit 431 receives from the user terminal 200 an input of a defecation record manually inputted into the user terminal 200 by the user. The reception unit 431 receives manual input of a record of excretion by a user using a toilet other than the toilet 7 of the toilet system TS.

The reception unit 431 also functions as an acquisition unit that acquires information. The reception unit 431 acquires various information from the storage unit 420. The reception unit 431 receives various information from the toilet seat device 2 and the user terminal 200. The receiving unit 431 receives information regarding stools from the toilet seat device 2 . The reception unit 431 receives the excretion record from the toilet seat device 2. The reception unit 431 receives the stool image (data) from the toilet seat device 2 . The reception unit 431 is provided in the toilet seat device 2 placed on the top of the toilet bowl 7 in which the bowl part 8 for receiving excrement is formed, and receives a stool image based on information from the stool quality sensor 302 in order to detect stool. get. The reception unit 431 stores the acquired stool image in the defecation information database 421.

The registration unit 432 performs a process of registering various types of information. The registration unit 432 registers excretion information (excretion record) acquired from the toilet seat device 2. The registration unit 432 stores the excretion information in the storage unit 420. For example, the registration unit 432 registers the excretion information in the defecation information database 421 in association with the user identification information.

The registration unit 432 registers the information accepted by the reception unit 431 in the storage unit 420. The registration unit 432 stores in the defecation information database 421 the defecation record of manual defecation in a toilet other than the toilet bowl 7, which has been accepted by the reception unit 431. The registration unit 432 automatically records in the defecation information database 421 an excretion record including excretion information detected by various sensors (detection units) and date and time information of defecation acquired by the clock unit 232. For example, the registration unit 432 assigns a first label to the excretion record acquired by the detection by the toilet seat device 2 and stores it in the defecation information database 421. For example, the registration unit 432 assigns a second label to the excretion record manually input by the user using the user terminal 200 and stores it in the defecation information database 421. For example, the registration unit 432 assigns a first label to the excretion record received from the toilet seat device 2 and stores it in the defecation information database 421, and assigns a second label to the excretion record received from the user terminal 200 and stores it in the defecation information database 421. It is stored in the information database 421. The registration unit 432 stores information on the position of the toilet bowl in the defecation information database 421 along with the defecation record.

The providing unit 433 provides information. The providing unit 433 transmits information to an external information processing device via the communication unit 410. For example, the providing unit 433 transmits various information to the user terminal 200 and the toilet seat device 2. The providing unit 433 transmits the excretion record stored in the memory unit 420 to the user terminal 200, etc.

The providing unit 433 functions as a generating unit that performs a generating process of various information. The providing unit 433 generates content showing the excretion record to be displayed on the user terminal 200. The providing unit 433 generates a screen (content) showing the excretion record. For example, the providing unit 433 generates content (image information) to be provided to the user terminal 200 by appropriately using various technologies related to image generation, image processing, etc. For example, the providing unit 433 generates a screen (image information) to be provided to the user terminal 200 by appropriately using various technologies such as Java (registered trademark). In addition, the providing unit 433 may generate content (image information) to be provided to the user terminal 200 based on the format of CSS (Cascading Style Sheets), JavaScript (registered trademark), or HTML (Hyper Text Markup Language). Furthermore, for example, the providing unit 433 may generate content in various formats, such as JPEG (Joint Photographic Experts Group), GIF (Graphics Interchange Format), and PNG (Portable Network Graphics). The providing unit 433 transmits the generated content to the user terminal 200, etc. For example, the providing unit 433 generates a manual input screen and transmits the generated manual input screen to the user terminal 200.

The providing unit 433 functions as a notification unit (alert unit) that performs notification processing of various information. If there is no record in the defecation information database 421 for a predetermined period of time, the providing unit 433 issues an alert to encourage input to the defecation information database 421. If there is no registration of the user's excretion record for a period of time that exceeds the user's excretion interval, the providing unit 433 transmits notification content (for example, the display screen of the user terminal 200 in FIG. 17) to the user terminal 200 to encourage the user to input excretion information, and causes the user terminal 200 to display the notification content.

The providing unit 433 functions as an estimation unit that performs estimation processing of various information. The providing unit 433 calculates a predetermined period based on an estimated date and time of excretion estimated from the date and time information of excretion recorded in the defecation information database 421. For example, the providing unit 433 calculates a predetermined period based on the date and time information of excretion recorded in the defecation information database 421. The providing unit 433 calculates the user's excretion interval from the date and time information of excretion recorded in the defecation information database 421. The providing unit 433 calculates the average interval between excretions recorded in the defecation information database 421 as the user's excretion interval.

For example, the providing unit 433 estimates the next excretion date and time (estimated date and time) from the user's latest (last) excretion date and time and the user's excretion interval. For example, if the last excretion date and time is January 5th at 8:00, and the user's excretion interval is 24 hours, the provision unit 433 sets the expected next excretion date and time (estimated date and time) to January 6th at 8:00. It is estimated that it is time. In this case, the providing unit 433 calculates the difference (24 hours) between the last excretion date and time "January 5th 8:00" and the assumed date and time "January 6th 8:00" as the predetermined period. For example, if the excretion record has not been registered even after 24 hours have passed at 8 o'clock on January 5th, the providing unit 433 notifies the user to prompt the user to input the excretion record.

The providing unit 433 estimates an excretion record from the excretion record recorded in the defecation information database 421, and inputs the estimated excretion record to the input means. The providing unit 433 provides content including the estimated information. The providing unit 433 generates a manual input screen (content) in which estimated information corresponding to the user is preset, and provides it to the user terminal 200. The estimation of information will be described later.

<1-4. Manual input example>
Here, acquisition of excretion information regarding defecation performed by a user in a toilet (toilet bowl) that does not have an automatic recording function, such as a toilet other than the toilet system TS (also referred to as a "health toilet") will be explained. For example, when a user defecates in a normal toilet (toilet bowl) in which the toilet seat device 2 is not installed, the excretion information management system 1 accepts manual input of excretion information by the user. This point will be explained using FIGS. 7 and 8. 7 and 8 are diagrams showing an example of manual input of defecation information. Specifically, FIG. 7 is a diagram illustrating an example of a display transition during manual input of defecation information. Further, FIG. 8 is a diagram showing an example of a screen for selecting manual input. In addition, in FIG. 7, the user terminal 200 is shown as user terminal 200-1 and user terminal 200-2 according to the display transition, but they are the same user terminal 200, and when described without distinguishing them, they will be referred to as "user terminal 200-1" and "user terminal 200-2". Terminal 200" may be written as "Terminal 200".

In the example of FIG. 7, the user U excretes in a normal toilet (toilet bowl TL) that does not have an automatic recording function. In this case, the excretion information management system 1 accepts manual input of excretion information by the user, as shown in the user terminal 200-1. For example, as shown in the user terminal 200-1, the excretion information management system 1 causes the user terminal 200 to display a button BT1 indicating "Enter excretion in another toilet" along with information INF1 indicating the previous excretion record. Note that the server device 400 may generate content including the information shown in the user terminal 200-1 and transmit it to the user terminal 200. The received information may then be displayed on the user terminal 200.

In the example shown in FIG. 7, the user terminal 200-1 displays information INF1 indicating the excretion record at 7:30 on January 7th as the latest excretion record of the user U. Further, the user terminal 200-1 displays a button BT1 for allowing the user to perform manual input. When the button BT1 is selected by the user U, the user terminal 200 changes the display to a screen for accepting input of excretion information (also referred to as a "manual input screen"), as shown in the user terminal 200-2. For example, the user U causes the display of the user terminal 200 to transition to a manual input screen by touching an area of the user terminal 200 where the button BT1 is displayed with the hand UA. For example, when button BT1 is selected, user terminal 200 requests a manual input screen from server device 400, and displays the manual input screen received from server device 400.

In the example shown in FIG. 7, the user terminal 200-2 displays a manual input screen for receiving manual input of various items such as defecation time, shape of stool, amount of stool, color of stool, and place of defecation. The user U manually inputs each item displayed on the user terminal 200-2, such as the time of defecation, the shape of the stool, the amount of the stool, the color of the stool, and the place of defecation. Then, the user U who has completed the manual input registers the manually input information in the user terminal 200. For example, the user U causes the user terminal 200 to register the manually input information by selecting a button (such as button BT31 in FIG. 18) for registering the manually input information. For example, the user terminal 200 requests the server device 400 to register the excretion information manually input by the user U by transmitting the excretion information manually input by the user U to the server device 400 . The server device 400, which has received the excretion information manually input by the user U from the user terminal 200, converts the excretion information manually input by the user U into information indicating manual input (second label) and the user U's excretion information. Excretion information is registered in the defecation information database 421 in association with user identification information.

For example, if the toilet in your home or other place where you defecate on a daily basis has a function to acquire (automatically record) excretion information, a lot of data can be automatically acquired and there is no need to worry about keeping records of excretion. However, when people defecate in other toilets, such as those at work or school, data is missing and the excretion records cannot be interpreted correctly. Therefore, the excretion information management system 1 can acquire more sufficient history data by having the user manually input data from other toilets to eliminate missing data.

The excretion information management system 1 may collect excretion information by various means. This will be explained with reference to FIG. 8. The user terminal 200 in FIG. 8 displays a first button BT2 for allowing the user to perform manual input, and a second button BT3 for communicating with other toilets. For example, when the first button BT2 is selected by the user U, the user terminal 200 transitions the display to a manual input screen that accepts input of excretion information, as shown in the user terminal 200-2 in FIG. 7.

Further, for example, when the second button BT3 is selected by the user U, the user terminal 200 executes a process of searching for whether there is a toilet with an automatic recording function with which communication is possible. For example, the user terminal 200 determines whether there is a communicable toilet nearby by short-range communication or the like. For example, user U temporarily registers an ID (user identification information, etc.) on the toilet bowl by holding the user terminal 200 such as a smartphone over the toilet bowl, collates the ID, and checks the detection result (excretion information) is associated with information indicating automatic recording (first label) and stored in the server device 400. In addition, if there is a toilet that has an automatic recording function that allows communication, the user terminal 200 can register that toilet in advance, and select the registered toilet when using the toilet to detect the detected toilet. The excretion information may be registered in the server device 400 as information on excretion by the user U, and by registering it in advance, the trouble of temporary ID registration and verification can be saved. Thereby, the excretion information management system 1 may increase the number of toilets that can automatically record to a plurality of toilets like the excretion information management system 1A. For example, if there is a communicable toilet with an automatic recording function, the user terminal 200 communicates with that toilet, receives excretion information detected by that toilet, and transfers the received excretion information to the server. 400. The above is just an example, and the excretion information management system 1 acquires and manages the user's excretion information in toilets other than the toilet system TS through various processes if it is possible to obtain the user's excretion information. You may.

<1-5. Information display example＞
Here, an example of displaying information will be explained using FIGS. 9 and 10. FIG. 9 is a diagram showing an example of information display. Specifically, FIG. 9 is a diagram showing an example of information displayed on the user terminal 200 of a user who is using the toilet system TS (health toilet) in which the toilet seat device 2 is arranged. FIG. 10 is a diagram showing another example of information display. Specifically, FIG. 10 shows a case where the toilet system TS (healthy toilet) in which the toilet seat device 2 is arranged is not in use, for example, when a normal toilet (toilet bowl) in which the toilet seat device 2 is not arranged is in use. 2 is a diagram showing an example of information displayed on a user's user terminal 200. FIG.

9 and 10 may be generated by the server device 400 and provided to the user terminal 200. For example, the server device 400 may determine whether or not the user is using the toilet system TS (healthy toilet) in which the toilet seat device 2 is arranged based on the location information of the user terminal 200 acquired from the user terminal 200, and provide the information to the user terminal 200 based on the determination result. In this case, when the server device 400 determines that the user is using the toilet system TS (healthy toilet) in which the toilet seat device 2 is arranged, it provides the information as shown in FIG. 9 to the user terminal 200. Also, when the server device 400 determines that the user is not using the toilet system TS (healthy toilet) in which the toilet seat device 2 is arranged, it provides the information as shown in FIG. 10 to the user terminal 200. The user terminal 200 displays the information received from the server device 400. In addition, the user terminal 200 may determine whether or not the user is using the toilet system TS (healthy toilet) in which the toilet seat device 2 is installed, without going through the server device 400, and display either FIG. 9 or FIG. 10 based on the determination result.

First, FIG. 9 will be explained. The user terminal 200 in FIG. 9 shows a display example when the user is using the toilet system TS (health toilet) in which the toilet seat device 2 is arranged. The button BT11 displayed as "View results now" is used when viewing data in the restroom. For example, when button BT11 is selected, user terminal 200 displays the latest detection result (excretion information).

Further, the button BT12 displayed as "Download results" is used to view data automatically acquired and stored in the storage unit (for example, the defecation information database 421). For example, when the button BT12 is selected, the user terminal 200 requests the latest unconfirmed excretion information of the user from the server device 400, and displays the latest excretion information acquired from the server device 400.

The button BT13 labeled "View past results" is used to view data that has been acquired automatically and manually and stored in the memory unit (e.g., defecation information database 421). For example, when button BT13 is selected, the user terminal 200 requests the user's past excretion information from the server device 400, and displays the past excretion information acquired from the server device 400.

The button BT14, which is labeled "Manually register results," is used when the user manually inputs results. When the user is using the toilet system TS (healthy toilet) in which the toilet seat device 2 is installed, the button BT14 is displayed in an unselectable state. In FIG. 9, the user terminal 200 displays the button BT14 in an unselectable state. In this way, when the user is using the toilet system TS (healthy toilet), the user terminal 200 displays the buttons BT11, BT12, and BT13 other than the button BT14 in a selectable state.

Next, FIG. 10 will be explained. The user terminal 200 in FIG. 10 shows a display example when the user is using a normal toilet (toilet other than the health toilet) in which the toilet seat device 2 is not installed. Note that descriptions of points similar to those in FIG. 9 will be omitted as appropriate.

When the user is using a normal toilet (a toilet other than a health toilet) in which the toilet seat device 2 is not installed, the button BT11 is displayed in a non-selectable state. In FIG. 10, since the user is using a normal toilet (a toilet other than a health toilet) in which the toilet seat device 2 is not installed, the user terminal 200 displays the button BT11 in a non-selectable state.

When the user is using a normal toilet (a toilet other than a health toilet) that does not have a toilet seat device 2, the user terminal 200 displays buttons BT12, BT13, and BT14 other than button BT11 in a selectable state. For example, when button BT12 is selected, the user terminal 200 requests the server device 400 for the user's latest unconfirmed excretion information, and displays the latest excretion information acquired from the server device 400. For example, when button BT13 is selected, the user terminal 200 requests the server device 400 for the user's past excretion information, and displays the past excretion information acquired from the server device 400. For example, when button BT14 is selected, the user terminal 200 displays a screen for accepting input of excretion information (for example, the manual input screen of the user terminal 200-2 in FIG. 7).

2. Modified Examples
As described above, there may be a plurality of toilet systems TS that automatically record excretion records. This will be described below. In the excretion information management system 1A according to the modified example, the description of the same points as those in the excretion information management system 1 according to the embodiment will be omitted as appropriate.

<2-1. Configuration of excretion information management system>
The configuration of an excretion information management system according to a modified example will be described with reference to FIG. 11. FIG. 11 is a diagram illustrating a configuration example of an excretion information management system according to a modified example.

As shown in FIG. 11, the excretion information management system 1A includes a toilet system TS1, a toilet system TS2, a user terminal 200, and a server device 400. Like the toilet system TS described in the embodiment, the toilet system TS1 and the toilet system TS2 include a toilet seat device 2, an operating device 10, a seating sensor 301, and a stool property sensor 302. When describing the toilet system TS1 and the toilet system TS2 without distinguishing between them, they may be referred to as the toilet system TS.

In this way, the excretion information management system 1A includes multiple toilet systems TS with an automatic recording function, such as the toilet system TS1 and the toilet system TS2. That is, the excretion information management system 1A shows an example of a system in which there are multiple toilet systems TS (healthy toilets) in which toilet seat devices 2 are arranged. Note that the toilet system TS of the excretion information management system 1A may be registered as a toilet system TS (healthy toilet) that automatically records the excretion information of the user U, for example, by the user U holding the user terminal 200 such as his/her smartphone over the toilet seat device 2 or the like to register the toilet system TS2. For example, the toilet system TS2 may be registered as a toilet system TS (healthy toilet) that automatically records the excretion information of the user U, for example, by the user U holding the user terminal 200 over the toilet seat device 2 or the like during use to register the toilet system TS2.

<2-1. Example of processing by excretion information management system>
An example of processing in the excretion information management system will be described with reference to Fig. 12. Fig. 12 is a diagram showing an example of processing in the excretion information management system.

In the example of FIG. 12, a user U performs an excretory act on a toilet bowl 7 on which a toilet seat device 2 of the toilet system TS1 is placed. The toilet seat device 2 then transmits the detected excretion information of the user U to the server device 400 (step S1). The toilet seat device 2 of the toilet system TS1 associates the excretion information, including the detected date and time, with user identification information that identifies the user U and transmits the information to the server device 400. The toilet seat device 2 of the toilet system TS1 may also transmit information indicating the location of the toilet system TS1 (location information) to the server device 400.

Then, the server device 400 associates the received user identification information of the user U with the received excretion information and information indicating automatic recording (first label) and registers it in the defecation information database 421 (step S2). .

Then, the user U performs the act of defecating in the toilet bowl 7 in which the toilet seat device 2 of the toilet system TS2 is arranged. Then, the toilet seat device 2 transmits the detected excretion information of the user U to the server device 400 (step S3). The toilet seat device 2 of the toilet system TS2 associates excretion information including the detected date and time with user identification information for identifying the user U, and transmits the association to the server device 400. Note that the toilet seat device 2 of the toilet system TS2 may also transmit information (position information) indicating the position of the toilet system TS2 to the server device 400.

Then, the server device 400 registers the received excretion information and information indicating automatic recording (first label) in the defecation information database 421 in association with the received user identification information of the user U (step S4). . Thereby, the server device 400 can register the excretion information of the user U detected by different toilet systems TS, such as the toilet system TS1 and the toilet system TS2, as the excretion history of the user U, who is the same person. .

The server device 400 provides information indicating the excretion history of the user U to the user terminal 200 used by the user U (step S5). For example, in response to a request from the user terminal 200 used by the user U, the server device 400 transmits information indicating the excretion history of the user U to the user terminal 200 used by the user U. The user terminal 200 then displays the information received from the server device 400 (step S6). Thereby, the user U can check the records of excretion performed in a plurality of different toilet systems TS (toilets) such as the toilet system TS1 and the toilet system TS2.

<3. Display example>
An example of displaying an excretion record by the user terminal 200 will now be described with reference to FIGS. 13 to 18.

First, examples of displaying excretion records for each type of stool, such as shape, color, and amount, will be shown using FIGS. 13 to 15. FIG. 13 is a diagram showing an example of a display of an excretion record. Specifically, FIG. 13 is a diagram showing an example of display of excretion records regarding the shape of stool. FIG. 14 is a diagram showing an example of a display of an excretion record. Specifically, FIG. 14 is a diagram showing an example of display of excretion records regarding the color of stool. FIG. 15 is a diagram showing an example of a display of an excretion record. Specifically, FIG. 15 is a diagram showing an example of a display of an excretion record regarding the amount of stool. In FIGS. 13 to 15, line graphs are shown as an example of the display mode of excretion records. The display format of the excretion record is not limited to a line graph, but can also be a bar graph, pie chart, radar chart, other graph formats such as a bubble chart that shows the count of each shape by the size of the circle, a calendar format, or text. It may be information, or it may be a display mode in which a plurality of these are displayed.

<3-1. Example of displaying the shape of stool＞
First, FIG. 13 will be explained. For example, the server device 400 generates a graph GR1 in which shape information of excretion information (excretion records) stored for each date and time is arranged in chronological order. The server device 400 generates a graph GR1 that is a line graph in which the vertical axis indicates one of rolling, ticking, cracked, banana-shaped, soft, muddy, and water-like, and the horizontal axis indicates dates.

In the example of FIG. 13, the server device 400 uses the user U's excretion records for approximately 10 days from December 26th to January 7th to generate a graph GR1 that chronologically arranges the shapes of the user U's stool over those approximately 10 days. The server device 400 generates a graph GR1 to which information manually input by the user U from the user U's excretion records for approximately 10 days from December 26th to January 7th has been added, indicating that the information was manually input. The server device 400 refers to the defecation information database 421, and generates a graph GR1 to which information manually input was added for December 28th and January 5th, which are associated with the second label (manual), from the user U's excretion records for approximately 10 days from December 26th to January 7th.

Then, the server device 400 transmits information (contents) including the graph GR1 shown in FIG. 13 to the user terminal 200. The user terminal 200 receives information (contents) including the graph GR1 shown in FIG. 13 from the server device 400. The user terminal 200 then displays the information (contents) including the graph GR1 shown in FIG. 13. Note that the user terminal 200 may accept re-input by the user for December 28th and January 5th, which are associated with the second label (manual).

For example, if the user selects December 28th or January 5th in the displayed graph GR1, the user terminal 200 may display a screen for accepting input of stool shape (e.g., the manual input screen of the user terminal 200-2 in FIG. 7) and accept re-input of stool shape by the user. When the user re-inputs stool shape, the user terminal 200 transmits the stool shape information re-input by the user from the server device 400 together with the corresponding date and time information. The server device 400 updates the stool shape information for the received date and time to the stool shape information re-input by the user.

<3-2. Example of stool color display>
Next, Fig. 14 will be described. For example, the server device 400 generates a graph GR2 in which color information from the excretion information (excretion record) stored for each date and time is arranged in chronological order. The server device 400 generates the graph GR2, which is a line graph in which the vertical axis indicates one of yellow, light yellow ochre, yellow ochre, brown, dark brown, and dark dark brown, and the horizontal axis indicates the date.

In the example of FIG. 14, the server device 400 uses user U's excretion record for about 10 days from December 26th to January 7th, and calculates the color of user U's stool during the about 10 days. A graph GR2 arranged in series is generated. The server device 400 generates a graph with information indicating that the information manually inputted by the user U is manually inputted among the excretion records of the user U for about 10 days from December 26th to January 7th. Generate GR2. The server device 400 refers to the defecation information database 421 and selects 12 of user U's defecation records for about 10 days from December 26th to January 7th that are associated with the second label (manual). For the 28th of the month and the 5th of January, a graph GR2 is generated to which information indicating that the information is manually input is added.

Then, the server device 400 transmits information (contents) including the graph GR2 shown in FIG. 14 to the user terminal 200. The user terminal 200 receives information (contents) including the graph GR2 shown in FIG. 14 from the server device 400. The user terminal 200 then displays the information (contents) including the graph GR2 shown in FIG. 14. Note that the user terminal 200 may accept re-input by the user for December 28th and January 5th, which are associated with the second label (manual).

For example, when the user selects December 28th or January 5th in the displayed graph GR2, the user terminal 200 displays a screen that accepts the input of the stool color (for example, user terminal 200-2 in FIG. 7). (manual input screen) may be displayed to accept the user's re-input of the stool color. When the user re-inputs the color of the stool, the user terminal 200 transmits the information on the color of the stool re-inputted by the user from the server device 400 together with the corresponding date and time information. The server device 400 updates the received date and time flight color information to the flight color information re-entered by the user.

<3-3. Example of displaying amount of stool＞
Next, FIG. 15 will be explained. For example, the server device 400 generates a graph GR3 in which information on the amount of excretion information (excretion records) stored for each date and time is arranged in chronological order. The server device 400 generates a graph GR3, which is a line graph in which the vertical axis indicates either very high, high, medium, low, or very low, and the horizontal axis indicates dates.

In the example of FIG. 15, the server device 400 uses user U's excretion records for about 10 days from December 26th to January 7th, and calculates the amount of user U's feces over the period of about 10 days. A graph GR3 arranged in series is generated. The server device 400 generates a graph with information indicating that the information manually inputted by the user U is manually inputted among the excretion records of the user U for about 10 days from December 26th to January 7th. Generate GR3. The server device 400 refers to the defecation information database 421 and selects 12 of user U's defecation records for about 10 days from December 26th to January 7th that are associated with the second label (manual). For the 28th of the month and the 5th of January, a graph GR3 is generated to which information indicating that the information is manually input is added.

Then, the server device 400 transmits information (content) including the graph GR3 shown in FIG. 15 to the user terminal 200. User terminal 200 receives information (content) including graph GR3 shown in FIG. 15 from server device 400. The user terminal 200 then displays information (content) including the graph GR3 shown in FIG. 15. Note that the user terminal 200 may accept re-input by the user for December 28th and January 5th, which are associated with the second label (manual).

For example, when the user selects December 28th or January 5th in the displayed graph GR3, the user terminal 200 displays a screen that accepts input of the amount of stool (for example, user terminal 200-2 in FIG. 7). (manual input screen) may be displayed to accept re-input of the amount of stool by the user. When the user re-enters the amount of stool, the user terminal 200 transmits the information on the amount of stool re-entered by the user from the server device 400 together with the corresponding date and time information. The server device 400 updates the information on the amount of flights at the received date and time to the information on the amount of flights re-entered by the user.

<3-4. Example of location display>
The display mode of the excretion record is not limited to each type, and may be various display modes. For example, the user terminal 200 may arrange the letters and numbers of the excretion record in chronological order and display them in chronological order. In this case, the server device 400 generates content (content CX) in which the characters and numbers of the excretion record are arranged in chronological order, and transmits it to the user terminal 200. The user terminal 200 then displays the received content CX. For example, the user terminal 200 may display the defecation information database 421 shown in FIG.

The user terminal 200 may also display the excretion record in association with the location. This will be explained with reference to FIG. 16. FIG. 16 is a diagram showing an example of a mapped display.

For example, the server device 400 refers to the excretion information (excretion records) stored for each date and time, and counts the number of excretion actions for each location (area). In the example of FIG. 16, the server device 400 counts the number of excretion actions for each location (area) by prefecture. The server device 400 then generates content CY in which the points increase the more frequently the excretion action occurs. In the example of FIG. 16, the server device 400 generates content CY including the largest point P1 corresponding to Tokyo, which has the highest number of excretion actions. The server device 400 also generates content CY including point P2 corresponding to Tochigi, point P3 corresponding to Hokkaido, and point P4 corresponding to Ehime, which are other locations where excretion actions have occurred.

The server device 400 transmits the content CY to the user terminal 200. Then, the user terminal 200 displays the received content CY.

<3-5. Example of notification prompting input>
The excretion information management system 1 may issue a notification to prompt the user to input excretion information if there is no registration of the user's excretion record for a predetermined period (e.g., a period longer than the user's excretion interval, such as 24 hours). This point will be described with reference to FIG. 17. FIG. 17 is a diagram showing an example of a notification to prompt the user to input information. The predetermined period is calculated based on the excretion date and time information. The server device 400 may use the excretion interval estimated from the interval between the excretion dates and times as the predetermined period.

In addition, the information displayed on the user terminal 200 in FIG. 17 may be generated by the server device 400 and provided to the user terminal 200. The server device 400 refers to the defecation information database 421, and if the difference between the date and time of the user's last defecation and the current date and time exceeds the user's defecation interval, instructs the user terminal 200 of the user to issue a notification prompting input. For example, the server device 400 may transmit content including the text information TX1 and button BT21 in FIG. 17 to the user terminal 200 and display the content on the user terminal 200, thereby instructing the user terminal 200 to issue a notification prompting input.

In the example shown in FIG. 17, the user terminal 200 displays text information TX1 such as "24 hours have passed since the last excretion. Have you forgotten to enter anything?" and a button BT21 labeled "Enter manually". The text information TX1 is information for notifying the user that an excretion record has not been registered for a period exceeding the user's excretion interval (24 hours in the example of FIG. 17). The button BT21 is a button for making the user enter information manually, and when the button BT21 is selected by the user, the user terminal 200 displays a screen for accepting the entry of excretion information (for example, the manual entry screen of the user terminal 200-2 in FIG. 7). This allows the excretion information management system 1 to prompt the user to enter information manually, and to prevent data loss. Note that even if the user is notified that an excretion record has not been registered for a period exceeding a predetermined period, there may be cases where there is truly no excretion, rather than a user forgetting to enter information. In this case, the fact that there has been no excretion for a predetermined period may be registered by inputting into the user terminal 200 that there was no forgetting to enter information.

<3-6. Display example of estimated information>
When displaying the manual input screen, the excretion information management system 1 may set estimated information (estimated information) in advance and display it. This point will be explained using FIG. 18. FIG. 18 is a diagram illustrating an example of a display of estimated information.

Note that the information displayed on the user terminal 200 in FIG. 18 may be generated by the server device 400 and provided to the user terminal 200. For example, when the user selects the button BT1 in FIG. 7 or the button BT21 in FIG. 17, the server device 400 generates a manual input screen (content) in which estimated information corresponding to the user is set in advance. and provides it to the user terminal 200. For example, the server device 400 transmits content including information for registering manually input information, button BT31, etc. in FIG. 18 to the user terminal 200.

In the example shown in FIG. 18, the user terminal 200 estimates the time of defecation as "7 o'clock", the shape of the stool as "soft", the amount of stool as "100g to 250g" (medium), and the color of the stool as "brown". Display a preset manual input screen. The time of excretion "7 o'clock" may be, for example, the time at the time of display, or the time obtained by adding the user's excretion interval to the last excretion date and time. For example, the server device 400 calculates the time of defecation to be set by adding the user's defecation interval to the user's last defecation date and time.

Further, the shape of the stool "soft" may be, for example, the shape most frequently observed in the user's defecation record, or the shape of the last defecation. For example, the server device 400 counts each shape in the user's defecation record stored in the defecation information database 421, and estimates the shape that occurs most frequently as the shape of the user's defecation.

Further, the amount of stool "100g to 250g" may be, for example, the average value of the amount in the user's defecation record or the amount at the last defecation. For example, the server device 400 calculates the average value of the amount of defecation records of the user stored in the defecation information database 421, and estimates the average value as the amount of feces of the user.

The stool color "brown" may be, for example, the color most frequently occurring in the user's defecation record or the color of the last excretion. For example, the server device 400 counts each color in the user's defecation record stored in the defecation information database 421, and estimates the most frequently occurring color as the color of the user's stool.

In the example of FIG. 18, the server device 400 generates a manual input screen (contents) in which the excretion time is set to "7:00", the shape of the stool is "soft", the amount of the stool is "100g to 250g", and the color of the stool is "brown", and transmits it to the user terminal 200. Then, as shown in FIG. 18, the user terminal 200 displays the manual input screen (contents) in which the excretion time is set to "7:00", the shape of the stool is "soft", the amount of the stool is "100g to 250g", and the color of the stool is "brown". In this way, when a user wants to register excretion information related to excretion performed in a toilet (toilet bowl) that does not have an automatic recording function, such as a toilet other than the toilet system TS (healthy toilet), by setting and displaying (inputting) estimated information in advance, the user can correct the estimated information if it is incorrect, and register the estimated information if it is correct. Therefore, the excretion information management system 1 can reduce the complexity of manual input by the user and can promote manual input by the user.

<3-6-1. Estimated example>
The excretion information management system 1 may estimate information using various information other than the above. For example, the excretion information management system 1 may calculate the time and the characteristics of the stool from the average over the past few weeks. For example, if a user has a tendency to have regular bowel movements at 8 o'clock on average in the past week, the excretion information management system 1 may estimate (predict) that the user will also have a regular bowel movement at 8 o'clock next time. ) may be used.

For example, the excretion information management system 1 may estimate based on the previous excretion result. For example, if a user has hard stools in the morning and then tends to have soft stools in the evening, if the user has hard stools in the morning, the excretion information management system 1 may You can assume that it will come out. In addition, for example, the excretion information management system 1 allows the user to have regular stools in the morning, if there is a tendency for the user to have regular stools the next morning, or if the user has regular stools in the morning. It can be assumed that there will be a normal flight the next morning. Note that the estimation may not be made only from the previous defecation results, but also from the trends of the past two or more defecation results or the trends of the user's defecation records stored in the defecation information database.

For example, the excretion information management system 1 may make an estimate based on trends for each day of the week. For example, if a user has a tendency to have hard stools on Monday mornings, the excretion information management system 1 may estimate that the user will have hard stools on Monday mornings. For example, if a user has a tendency to have normal stools on Friday evenings, the excretion information management system 1 may estimate that the user will have normal stools on Friday evenings.

For example, the excretion information management system 1 may acquire location information and make an estimate based on the tendency for each location. For example, if a user tends to have normal stools in the morning when at home, and the user is at home during the morning hours (e.g., 7:00-10:00, etc.), the excretion information management system 1 may estimate that the user will have normal stools. For example, if a user tends to have loose stools in the evening when out, and the user is at a location different from his/her home and workplace during the evening hours (e.g., 4:00-7:00, etc.), the excretion information management system 1 may estimate that the user will have loose stools.

For example, the excretion information management system 1 may estimate trends in conjunction with a schedule. For example, if a user tends to have loose stools before a meeting, the excretion information management system 1 may estimate that the user will have loose stools before the meeting.

In each of the above-described embodiments and modified examples, the excretion information management system 1 has been described as a biological information management system. The present invention is not limited to the excretion information management system 1, i.e., a system for managing excretion information, but may also be a system for managing biological information. The biological information may be at least one of information related to stool, information related to urine, information related to bowel gas, information related to blood flow, and information related to heart rate.

In addition, when the above-mentioned multiple pieces of biometric information are acquired, and when it is detected that at least one piece of the multiple pieces of biometric information has been acquired but at least one piece of biometric information has not been acquired, a display may be displayed on the display unit to encourage the input of the biometric information that has not been acquired. For example, when information on stool is acquired but information on blood flow is not acquired, a display may be displayed on the display unit to encourage the input of information on blood flow.

The above-described embodiments and variations can be combined as appropriate to the extent that they do not cause any inconsistencies in the processing content.

Further advantages and modifications may readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above.
