Summary of the Invention

Problems to be Solved by the Invention

[0004] However, there is room for improvement in the above-described conventional technology. For example, even if the overview of the intestinal environment (intestinal environment index) changed by the user's diet and lifestyle is visualized and provided to the user, there is a problem that it is difficult for the user to interpret whether the numerical value is good or bad.

[0005] An object of the disclosed embodiments is to provide a toilet system capable of displaying the overview of the intestinal environment understandable from defecation gas in an easy-to-understand manner to the user.

Means for Solving the Problems

[0006] A toilet system according to one embodiment of the system comprises: a storage means for storing defecation gas data related to defecation gas acquired in a toilet space, along with identification information and date and time information; a user operation means for receiving user operations; and a data display means for displaying a time-series information screen that divides the defecation gas data for a specified period set by the user operations received by the user operation means into time-series data, wherein the data display means displays the results of evaluating the defecation gas data on the time-series information screen using a first indicator and a second indicator, the first indicator being an indicator for evaluating the defecation gas data based on a predetermined first criterion, and the second indicator being an indicator for evaluating the defecation gas data based on a second criterion different from the first criterion.

[0007] Because intestinal environment indicators are not commonly used, it is difficult to judge their quality. Furthermore, the criteria for judging quality vary depending on factors such as the user's age and gender, making it difficult to make a judgment using a single indicator. Therefore, according to one embodiment of the toilet system, by representing the same stool gas data with two different indicators, a multifaceted evaluation can be viewed at a glance.

[0008] A toilet system according to one embodiment of the system has a first criterion which has a plurality of evaluation levels divided into predetermined numerical values, and a second criterion which has a plurality of evaluation levels divided into ranges different from the plurality of evaluation levels of the first criterion.

[0009] According to one embodiment of the toilet system, defecation gas data can be comprehensively evaluated based on multiple evaluation indicators, allowing for a more multifaceted analysis and understanding of the current intestinal environment.

[0010] In a toilet system according to one embodiment, the storage means further stores the user's personal attribute information, and the second criterion is determined based on the user's personal attribute information.

[0011] Defecation gas data is influenced by personal attributes (gender, age, residential area, etc.). Therefore, according to one embodiment of the toilet system, health status can be recognized based on judgment criteria appropriate to personal attribute information.

[0012] In a toilet system according to one embodiment, the storage means further stores the user's personal attribute information, and the second criterion is determined based on the defecation gas data of a plurality of users similar to the user's personal attribute information.

[0013] Defecation gas data is influenced by personal attributes (gender, age, residential area, etc.). Therefore, according to one embodiment of the toilet system, users can indirectly recognize their ranking (standard score) compared to others.

[0014] In a toilet system according to one embodiment, the second indicator is updated when the user's personal attribute information is changed.

[0015] According to one embodiment of the toilet system, by changing the indicators according to changes in an individual's age and living area, it becomes possible to perform evaluations that are appropriate to the situation at any given time.

[0016] In a toilet system according to one embodiment, the data display means further displays a reference value based on the user's past defecation gas data or set by the user's operation.

[0017] Intestinal environment indicators vary from person to person, with average values ​​for a generally healthy individual and target states being subject to individual differences. Therefore, according to one embodiment of the toilet system, by displaying target values ​​tailored to the individual user, it is possible to check whether there are any abnormalities within oneself or whether the target has been achieved.

[0018] In one embodiment of the toilet system, the reference value is generated based on the user's defecation gas data acquired during the period displayed on the display screen.

[0019] According to the toilet system according to one aspect of the embodiment, by generating and displaying a reference value based on the user's data during the displayed period, it is possible to check whether there is any abnormality in oneself.

[0020] In the toilet system according to one aspect of the embodiment, the reference value is generated based on the acquired data of the user for two or more weeks in the past.

[0021] The intestinal environment changes slowly over at least two weeks. Therefore, according to the toilet system according to one aspect of the embodiment, by generating and displaying a reference value based on the user's data for two or more weeks, it is possible to check whether there is any abnormality in oneself based on the reference value that is not affected by sudden dietary habits or the like.

[0022] The toilet system according to one aspect of the embodiment further includes input means for inputting the user's body feeling information, and the reference value of the user is generated based on the user's data when the body feeling is good among the body feeling information.

[0023] There are individual differences in the average value and the target state when a person is approximately healthy for intestinal environment indicators. Therefore, according to the toilet system according to one aspect of the embodiment, by displaying a reference value suitable for the individual user, it is possible to check whether there is any abnormality in oneself or whether the target has been achieved.

Effect of the Invention

[0024] According to one aspect of the embodiment, it is possible to display the general situation of the intestinal environment understood from the defecation gas in an easy-to-understand manner for the user.

[0026] The embodiments of the toilet system disclosed herein will be described in detail below with reference to the attached drawings. However, the present invention is not limited to the embodiments shown below. Furthermore, each embodiment can be combined as appropriate.

[0027] [Introduction] (Example of overall structure) Before providing a detailed description of the processes performed in the toilet system 10 according to the first to third embodiments, we will first explain the contents common to the toilet system 10 according to the first to third embodiments.

[0028] Figure 1 shows an example of the configuration of a toilet system according to an embodiment. As shown in Figure 1, for example, the toilet system 10 includes a display device 100 that displays information indicating the state of the user's intestinal environment, a toilet seat device 200 that acquires personal identification information and defecation gas data when the user defecates, and a cloud server 300 connected to the display device 100 and the toilet seat device 200 that stores data related to the user's defecation gas data and intestinal environment indicators. Note that the configuration of the toilet system 10 shown in Figure 1 is just an example, and the number of each device is not particularly limited.

[0029] The display device 100 is a display device (computer) that displays information to be provided to the user. For example, the display device 100 may be a user terminal (mobile terminal) owned by the user. In this case, the display device 100 can be implemented as, for example, a smartphone, a mobile phone, a PDA (Personal Digital Assistant), a tablet terminal, or a notebook PC (Personal Computer). For example, the display device 100 is connected to the control device included in the toilet seat device 200 via a predetermined network, either by wire or wireless communication.

[0030] The display device 100 has an application installed that displays graph data showing the state of the user's intestinal environment, etc., based on defecation gas data acquired by the toilet seat device 200 (hereinafter also referred to as the "intestinal health app"). The display device 100 displays information desired by the user in response to operations on the intestinal health app. The display device 100 is also connected to a cloud server 300 so as to be able to communicate with it, and can also display lifestyle information, etc., of other users who have installed the intestinal health app.

[0031] The toilet seat device 200 is a system that generates data indicating the state of the user's intestinal environment by acquiring personal identification information and measuring defecation gas data during the user's defecation, and includes, for example, a detection device and a control device, which will be described later.

[0032] Figure 2 shows an example of an overall overview of a toilet seat device according to the embodiment. In Figure 2, only a portion of the toilet system 10 necessary for explanation is shown, and explanations of points similar to those described above are omitted as appropriate.

[0033] As shown in Figure 2, the toilet seat device 200 has a configuration including a first detection unit 221, a second detection unit 222, and a control device 223. The toilet seat device 200 is a device placed in the toilet room R. The toilet seat device 200 communicates with other devices such as the display device 100 and the cloud server 300. The toilet seat device 200 can perform processing (personal identification) to acquire information for identifying the user who uses the toilet 207 in the toilet room R for defecation.

[0034] The toilet seat device 200 collects information from multiple users, such as family members, by distinguishing each user through personal identification. For example, the toilet seat device 200 obtains information to identify the user who uses the toilet 207 for excretion, and performs personal identification of the user, through communication with a display device 100 owned by the user or through the user's operation of the operating device 230 described later. For example, the toilet seat device 200 communicates with a display device 100 owned by the user and receives a user ID (hereinafter simply referred to as "ID"), which is user identification information for identifying the user, from the display device 100. The toilet seat device 200 may identify the user by any method as long as it is possible to identify the user who uses the toilet 207 in the toilet room R for excretion.

[0035] As shown in Figure 2, the first detection unit 221 has a light receiving unit 250 and detects feces. The second detection unit 222 has a gas sensor 240 and detects defecation gas. The control device 223 is a computer (information processing device) that performs a process to estimate information about the user's health (also called "estimation processing") based on the detection results of the first detection unit 221 and the second detection unit 222, and controls the output of the estimation processing results to an external device. The control device 223 estimates intestinal environment indicators through the estimation processing, but this will be explained later.

[0036] Furthermore, the control device 223 communicates with the display device 100, which displays information to the user, using short-range wireless communication functions such as Bluetooth®, BLE (Bluetooth Low Energy), and infrared. The control device 223 may also communicate with the display device 100 without going through the network N. The control device 223 may be connected to the display device 100 or other devices in any way as long as it is capable of sending and receiving information, and may be connected via a predetermined network (network N, etc.), such as the Internet, by wired or wireless connection.

[0037] Figure 2 shows a case where the toilet seat device 200 has a first detection unit 221, a second detection unit 222, and a control device 223, but it is not limited to this. For example, the control device 223 may be provided in a separate device (such as a housing) from the first detection unit 221 and the second detection unit 222, and may control the first detection unit 221 and the second detection unit 222 and acquire information by communicating with them wirelessly or via wired means.

[0038] Furthermore, the control device 223 may be located outside the toilet room R. In this case, the control device 223 may be connected to devices located inside the toilet room R, such as the toilet seat device 200, the first detection unit 221, and the second detection unit 222, via a predetermined network (network N, etc.) such as the Internet, either by wired or wireless communication, and capable of acquiring desired information.

[0039] Furthermore, the first detection unit 221 and the second detection unit 222 may be controlled by a control means separate from the control device 223. In this case, the control device 223 is a first control device that performs various information processing such as estimation processing, and the toilet seat device 200 may have a second control device, which is a separate device from the control device 223, function as a device that controls the first detection unit 221 and the second detection unit 222. Thus, the toilet seat device 200 may function as a system having a control device 223, which is a first control device that performs various information processing such as estimation processing using information from the first detection unit 221 and the second detection unit 222, and a detection unit control device, which is a second control device that controls the first detection unit 221 and the second detection unit 222.

[0040] For example, the first control device and the second control device may be connected via a predetermined network (network N, etc.) such as the Internet, and communicate via wired or wireless means. The first control device may perform estimation processing using the detection results from the first detection unit 221 and the detection result information from the second detection unit 222 received from the second control device. For example, the first control device may be a portable terminal (device) such as a smartphone or laptop computer that can be carried by the administrator of the toilet seat device 200.

[0041] The cloud server 300 stores information collected from the display device 100 and the toilet seat device 200 in its storage area. For example, the cloud server 300 collects health information for multiple users collected from multiple display devices 100 and multiple toilet seat devices 200, and stores this information for each user in its storage area. The cloud server 300 stores health information for a user in its storage area, associating it with information that identifies the user (such as an ID).

[0042] (Example of toilet room layout) Next, we will describe an example of the toilet room configuration common to each embodiment. Figure 3 is a perspective view showing an example of the toilet room configuration according to the embodiment. Note that in Figure 3, the toilet seat 205 and toilet lid 209 are shown transparently in order to illustrate the configuration of the measuring device 204 and the first detection unit 221.

[0043] As shown in Figure 3, a toilet bowl 207 is installed on the floor surface F in the toilet room R. In the following, the direction from the floor surface F towards the space of the toilet room R may be referred to as "up". Components of the toilet seat device 200, including a suction device 210, a measuring device 204 that performs gas detection including a second detection unit 222 which is a gas detection device, and a first detection unit 221, are arranged in the toilet room R.

[0044] The toilet bowl 207 is a toilet bowl, and a bowl portion 208 is formed in the toilet bowl 207. The bowl portion 208 has a downward recessed shape and is the part that receives the user's excrement. The toilet bowl 207 is not limited to the floor-standing type as shown in the figure, but can be of any type as long as the toilet seat device 200 can be applied, and may also be a wall-mounted type, etc. The toilet bowl 207 is provided with a rim portion around the entire circumference of the end of the opening facing the bowl portion 208. In the toilet room R, for example, a flush water tank for storing flush water may be installed near the toilet bowl 207, or it may be a so-called tankless type without a flush water tank.

[0045] For example, when a flushing control unit (not shown) installed in the toilet room R is operated by the user, flushing water is supplied to the bowl portion 208 of the toilet bowl 207, thereby flushing the toilet. The flushing control unit may be an operating lever or a touch operation on a toilet flushing object displayed on the operating device 230. Note that the flushing control unit is not limited to one that allows the user to perform flushing manually, such as with an operating lever, but may also be one that performs flushing by detecting the user's body with a sensor that detects the user, such as a seating sensor.

[0046] The toilet seat device 200 is mounted on top of the toilet bowl 207 and comprises a main body 203, a measuring device 204, a toilet seat 205, a washing nozzle 206, and a first detection unit 221. The toilet seat device 200 is placed on top of the toilet bowl 207, which has a bowl portion 208 for receiving excrement. The toilet seat device 200 is placed on top of the toilet bowl 207 so that the washing nozzle 206 advances into the bowl portion 208 before spraying washing water. The toilet seat device 200 may be detachably attached to the toilet bowl 207, or it may be attached to be integrated with the toilet bowl 207.

[0047] The toilet seat device 200 measures the biological information of the user of the toilet room R based on the fecal gas discharged into the bowl portion 208 of the toilet bowl 207 installed in the toilet room R, using a configuration including a measuring device 204. The measuring device 204 has a suction device 210 and a second detection unit 222. The toilet seat device 200 measures the biological information of the user of the toilet room R based on the feces discharged into the bowl portion 208 of the toilet bowl 207 installed in the toilet room R, using a configuration including a first detection unit 221. The measuring device 204 and the first detection unit 221 are described in detail in Figure 4.

[0048] As shown in Figure 3, the toilet seat 205 is formed in an annular shape and is positioned along the edge (rim) of the bowl portion 208, overlapping the opening of the toilet bowl 207. The user sits on the toilet seat 205. The toilet seat 205 functions as a seat that supports the buttocks of the seated user. The toilet lid 209 is attached to the toilet seat device 200 as needed, and the toilet seat device 200 does not necessarily have a toilet lid 209.

[0049] The cleaning nozzle 206 is a nozzle for discharging cleaning water. The cleaning nozzle 206 is configured to move forward and backward relative to the housing of the main unit 203 by being driven by a drive source such as an electric motor. The cleaning nozzle 206 is also connected to a water source such as a water pipe (not shown). As shown in Figure 1, when the cleaning nozzle 206 is in the extended position relative to the housing of the main unit 203 (also called the "extended position"), it sprays water from the water source onto the user's body to clean the area.

[0050] Figure 3 shows the state in which the cleaning nozzle 206 is extended. Note that the cleaning nozzle 206 may also be used for cleaning the inside of the toilet bowl 207 (bowl portion 208, etc.). The cleaning nozzle 206 may be used in a way that allows switching between a localized cleaning mode for cleaning the user's private parts and a toilet bowl cleaning mode for spraying water inside the toilet bowl 207. For example, the cleaning nozzle 206 may be used in a way that allows switching between the localized cleaning mode and the toilet bowl cleaning mode in response to control by the toilet seat device 200.

[0051] The operating device 230 is installed in the toilet room R. The operating device 230 is installed in a position that can be operated by the user. The operating device 230 is installed in a position that can be operated when the user is seated on the toilet seat 205. In Figure 3, the operating device 230 is installed on the left side wall W as viewed from the user seated on the toilet seat 205. The operating device 230 may be installed in various ways other than on the wall, as long as it can be used by the user seated on the toilet seat 205. For example, the operating device 230 may be installed integrally with the toilet seat device 200.

[0052] The operating device 230 is connected to the toilet seat device 200 via a predetermined network, either by wire or wireless communication. For example, the connection between the toilet seat device 200 and the operating device 230 can be any connection that enables the transmission and reception of information, and may be wired or wireless.

[0053] The operating device 230 accepts various operations from the user via a display surface (e.g., display screen 231) through, for example, a touch panel function. Alternatively, the operating device 230 may be equipped with switches and buttons, and accept various operations via these switches and buttons. The display screen 231 is a display screen of a tablet terminal, for example, implemented by a liquid crystal display or an organic EL (Electro-Luminescence) display, and is a display device for displaying various information. In other words, the operating device 230 accepts user input via the display screen 231 and also provides output to the user. The display screen 231 is a display device for displaying various information.

[0054] The operating device 230 receives user input to control various functions provided within the toilet room R. The operating device 230 also receives user input to control the execution of local washing by the toilet seat device 200. For example, the operating device 230 may have switches, buttons, etc. that receive the user input as described above, and may perform various processes in response to the user's contact with the switches, buttons, etc. Note that the above is just an example, and the operating device 230 may also receive user input to perform various processes. Furthermore, the user's smartphone or other display device 100 may have functions equivalent to those of the operating device 230.

[0055] The toilet seat device 200 measures the user's biological information based on the feces and defecation gases discharged into the bowl portion 208 of the toilet bowl 207 installed in the toilet room R, through various configurations and processes described later. The toilet seat device 200 performs control to appropriately measure the feces and defecation gases. Based on the information collected through measurements, the toilet seat device 200 provides information to the user's smartphone or other display device 100. The toilet seat device 200 may also provide information to the operation device 230 (or display screen 231) of the toilet room R based on the information collected through measurements.

[0056] (Configuration of the measuring device) Next, the configuration of the measuring device 204 will be described with reference to Figure 4. Figure 4 is a plan view showing an example of the configuration of the measuring device according to the embodiment. In the example shown in Figure 4, the measuring device 204 and the first detection unit 221 are shown as an example of being arranged within the main body 203. In Figure 4, the housing (cover) of the main body 203 where the measuring device 204 and the first detection unit 221 are arranged is removed to illustrate the configuration of the measuring device 204 and the first detection unit 221.

[0057] The measuring device 204 includes a suction device 210 that sucks gas from the bowl portion 208 of the toilet bowl 207, and a second detection unit 222 that detects the components of the sucked gas.

[0058] The suction device 210 has a fan for sucking gas from the bowl portion 208 of the toilet bowl 207. The suction device 210 is connected to a duct 211 that communicates with the bowl portion 208 of the toilet bowl 207. The duct 211 functions as a flow path for the gas in the bowl portion 208 to flow into the measuring device 204. The suction device 210 sucks gas from the bowl portion 208 using the duct 211 as a flow path by driving the fan. For example, the suction device 210 performs suction-related processing in accordance with the control of the control device 223. If the suction device 210 is shared with a deodorizing device or the like incorporated in the toilet seat device 200, the suction device 210 may be controlled by a control means (device) other than the control device 223.

[0059] The second detection unit 222 detects defecation gas. The second detection unit 222 detects information related to the intestinal environment. The second detection unit 222 performs processing related to the detection of the components of the gas aspirated by the suction device 210. In Figure 4, the second detection unit 222 is positioned downstream of the suction device 210 when viewed from the bowl section 208 side. Note that Figure 4 is merely an example, and the second detection unit 222 may be positioned at any location as long as it is in a position where the gas aspirated by the suction device 210 can be introduced. The second detection unit 222 is connected to a duct 212 that communicates with the outside of the main body section 203. The duct 212 functions as a flow path that allows the gas in the second detection unit 222 to flow out from the measuring device 204. For example, in response to the operation of the suction device 210, the gas in the second detection unit 222 is released outside the measuring device 204 through the duct 212.

[0060] For example, the second detection unit 222 performs processing related to gas detection in accordance with the control of the control device 223. The second detection unit 222 is equipped with a gas sensor 240 that reacts to gases contained in the gas. The gas sensor 240 detects specific components of the gas. For example, a semiconductor gas sensor is used for the gas sensor 240. Note that the above is just one example, and the gas sensor is not limited to a semiconductor gas sensor 240; multiple types of sensors of any configuration may be used. Furthermore, the gas sensor 240 may be used as a single unit combining sensors of multiple principles, such as a semiconductor type and an infrared absorption type. For example, the gas sensor 240 detects fecal gas, which indicates the user's intestinal environment, but this point will be described later.

[0061] The first detection unit 221 detects feces. The first detection unit 221 detects information related to intestinal peristalsis. The first detection unit 221 detects feces (defecation) excreted by the user by imaging the inside of the bowl portion 208 of the toilet bowl 207. The first detection unit 221 is an image sensor. The first detection unit 221 has a light receiving unit 250. For example, the light receiving element is a line sensor in which CCD (Charge Coupled Device) sensors or CMOS (Complementary Metal Oxide Semiconductor) sensors are arranged in a line. Note that the light receiving element is not limited to a line sensor (one-dimensional image sensor), but various sensors such as area sensors (two-dimensional image sensors) may be used.

[0062] (Functional configuration of toilet seat device) Next, the functional configuration of the toilet seat device 200 will be described with reference to Figure 5. Figure 5 is a block diagram showing an example of the configuration of a toilet seat device according to this embodiment. As shown in Figure 5, the toilet seat device 200 includes a human presence sensor 232, a seating sensor 233, an illuminance sensor 234, a control device 223, a nozzle motor 261, and a washing nozzle 206.

[0063] Note that the configuration of the toilet seat device 200 shown in Figure 5 is merely an example, and if each component is provided individually, the toilet seat device 200 may have only a toilet seat 205. Thus, the configuration of the toilet seat device 200 shown in Figure 5 is merely an example, and any configuration can be adopted for the toilet seat device 200. The motion sensor 232, seat sensor 233, illuminance sensor 234, etc., may be placed in any location as long as the desired sensing is possible. Furthermore, the toilet seat device 200 only needs to be able to detect when a user sits on the toilet seat 205, and only needs to have at least one of the motion sensor 232, seat sensor 233, and illuminance sensor 234. The toilet seat device 200 transmits and receives information between the display device 100 and an information processing device such as a cloud server 300 via a predetermined network (such as the Internet) using a communication device, either wired or wirelessly.

[0064] The human presence sensor 232 has the function of detecting a human body. For example, the human presence sensor 232 is used as a seating detection means to detect when a user sits on the toilet seat 205. For example, the human presence sensor 232 may be implemented by a pyroelectric sensor using an infrared signal. For example, the human presence sensor 232 may be implemented by a microwave sensor. For example, the human presence sensor 232 is an infrared light-emitting and receiving distance measuring sensor and may detect a human body present near the toilet seat 205 immediately before a person (user) sits on the toilet seat 205, or a user who has sat on the toilet seat 205.

[0065] The motion sensor 232 also functions as a seat-away detection sensor, detecting when a user leaves the toilet seat 205. The motion sensor 232 detects the user's seated state on the toilet seat 205. The motion sensor 232 outputs a detection signal to the control device 223. Note that the above is just one example, and the motion sensor 232 may detect a person (such as a user) approaching the toilet seat 205.

[0066] The seating sensor 233 has the function of detecting when a person sits on the toilet seat device 200. For example, the seating sensor 233 is used as a seating detection means to detect when a user sits on the toilet seat 205. For example, the seating sensor 233 can be implemented by a load sensor or the like. The seating sensor 233 detects when a user sits on the toilet seat 205. The seating sensor 233 is capable of detecting when a user sits on the toilet seat 205.

[0067] The seating sensor 233 also functions as a seating detection sensor that detects when a user leaves the toilet seat 205. The seating sensor 233 detects the user's seated state on the toilet seat 205. Note that the above is just one example, and the seating sensor 233 may detect a person sitting on the toilet seat device 200 by various means other than those described above. The seating sensor 233 outputs a seating detection signal to the control device 223.

[0068] The illuminance sensor 234 is a sensor that detects illuminance. For example, the illuminance sensor 234 is used as a seating detection means to detect when a user sits on the toilet seat 205. For example, the illuminance sensor 234 is positioned facing the bowl portion 208 and detects the illuminance inside the bowl portion 208.

[0069] The illuminance sensor 234 also functions as a seat-away detection sensor, detecting when a user leaves the toilet seat 205. The illuminance sensor 234 detects the user's seated state on the toilet seat 205. Note that the above is merely an example, and the illuminance sensor 234 may be placed in any position as long as it can detect the user's seating on the toilet seat 205 based on the illuminance.

[0070] The control device 223 controls various configurations and processes. The control device 223 is a computer (information processing device) that performs various information processing related to the detection (measurement) of feces and gas. The control device 223 can be any device as long as it has the necessary configuration for control, for example, a microcomputer.

[0071] The control device 223 controls various components for detecting (measuring) feces. The control device 223 controls the first detection unit 221. The control device 223 transmits control information to the first detection unit 221 for controlling the function of the electronic shutter of the light receiving unit 250. Note that the shutter function of the light receiving unit 250 is not limited to an electronic shutter; any method such as a mechanical shutter can be used as long as the desired detection is possible. Furthermore, if the first detection unit 221 has a light-emitting part such as a light-emitting element, the control device 223 may transmit control information to the first detection unit 221 for controlling the lighting or extinguishing of the light-emitting part.

[0072] For example, the control device 223 causes the first detection unit 221 to emit and receive light. The control device 223 controls the first detection unit 221 to irradiate light onto the light-emitting unit and cause the light-receiving unit 250 to receive the light. The control device 223 causes the first detection unit 221 to emit and receive light during the period when the seating sensor 233 detects that a user is seated on the toilet seat 205.

[0073] The control device 223 controls various configurations for detecting (measuring) gas. The control device 223 controls the second detection unit 222. The control device 223 transmits control information to the second detection unit 222 via a wired connection. Alternatively, the control device 223 may transmit control information to the second detection unit 222 wirelessly. For example, if the control device 223 is configured as a separate device from the toilet seat device 200, the control information of the second detection unit 222 may be transmitted wirelessly to the toilet seat device 200. In this case, the control device of the toilet seat device 200 may control the second detection unit 222 based on the received control information.

[0074] For example, the control device 223 may control the second detection unit 222 so that the measurement value from the gas sensor 240 falls within a predetermined range when the user is not using the toilet 207, and perform baseline control to control the measurement value used as the reference value (baseline) to a predetermined value. The control device 223 may also perform baseline control to control the baseline to a predetermined value by changing the resistance value of the resistive element of the gas sensor 240.

[0075] Furthermore, the control device 223 may control the suction device 210. For example, the control device 223 controls the start and stop of suction by the suction device 210. The control device 223 transmits control information to the suction device 210 via a wired connection. Alternatively, the control device 223 may transmit control information to the suction device 210 wirelessly. For example, if the control device 223 is configured as a separate device from the toilet seat device 200, it may transmit control information for the suction device 210 to the toilet seat device 200 wirelessly. In this case, the control device of the toilet seat device 200 may control the suction device 210 based on the received control information.

[0076] Furthermore, the control device 223 may also control various other components of the toilet seat device 200. The control device 223 controls the nozzle motor 261, etc. The control device 223 controls the nozzle motor 261, etc., based on signals transmitted from the operating device 230.

[0077] The control device 223 controls the nozzle motor 261 based on the control instruction signal for localized cleaning transmitted from the operating device 230. The control device 223 controls the nozzle motor 261 to move the cleaning nozzle 206 forward and backward. Note that the control device 223 may control various mechanisms other than the nozzle motor 261. For example, the control device 223 controls the opening and closing of a solenoid valve that has the function of a valve that controls the flow of fluid by an electromagnetic method. For example, by controlling the solenoid valve, the control device 223 switches the supply and stop of tap water from the water supply pipe.

[0078] The control device 223 transmits control information to the nozzle motor 261, etc., via a wired connection. Alternatively, the control device 223 may transmit control information to the nozzle motor 261, etc., via wireless connection. For example, if the control device 223 is configured as a separate device from the toilet seat device 200, it may transmit control information for the nozzle motor 261, etc., to the toilet seat device 200 via wireless connection. In this case, the control device of the toilet seat device 200 may control the nozzle motor 261, etc., based on the received control information.

[0079] The nozzle motor 261 is a drive source (motor) that drives the cleaning nozzle 206 forward and backward. The nozzle motor 261 performs control to move the cleaning nozzle 206 forward and backward relative to the main body 203. The nozzle motor 261 performs control to move the cleaning nozzle 206 forward and backward in response to instructions from the control device 223.

[0080] Furthermore, the control device 223 may control the toilet lid 209 and toilet seat 205 as shown in Figure 3. In this case, the control device 223 controls the toilet lid 209 and toilet seat 205 based on signals transmitted from the operating device 230. The control device 223 controls the toilet lid 209 based on control instruction signals regarding the opening and closing of the toilet lid transmitted from the operating device 230. The control device 223 controls the toilet seat 205 based on control instruction signals regarding the opening and closing of the seating area transmitted from the operating device 230. The control device 223 transmits control information to the toilet lid 209 and toilet seat 205 via wired connection. Alternatively, the control device 223 may transmit control information to the toilet lid 209 and toilet seat 205 wirelessly.

[0081] The control device 223 determines whether or not a user has been detected seated by seating detection means such as the motion sensor 232, seating sensor 233, and illuminance sensor 234. For example, the control device 223 determines whether or not a user has been detected seated by the seating sensor 233.

[0082] In the configuration shown in Figure 5, a configuration in which the toilet seat device 200 includes a control device 223, etc., is shown as an example. However, the control device 223, motion sensor 232, seat sensor 233, and illuminance sensor 234, etc., may be configured as separate devices from the toilet seat device 200. For example, the control device 223 may be configured as a separate device from the toilet seat device 200. For example, the control device 223 may be a server device and be located at a distance from the toilet seat device 200. In this case, the control device 223 communicates with each device such as the toilet seat device 200, motion sensor 232, seat sensor 233, and illuminance sensor 234, and receives various information from each device. In this case, the toilet seat device 200 may also have a configuration (control circuit, etc.) for controlling various components of the toilet seat device 200, such as the nozzle motor 261. Note that the above is merely an example, and the toilet seat device 200 can be configured in any way that allows for the desired processing.

[0083] Furthermore, while the toilet seat device 200 has been described in the above explanation as a device comprising both a first detection unit 221 for detecting feces and a second detection unit 222 for detecting defecation gas, it is not limited to this configuration. For example, the toilet seat device 200 may have only the second detection unit 222 and not the first detection unit 221. The following explanation will describe the process of estimating the user's intestinal environment from the processing of the second detection unit 222 and related defecation gas data. Here, defecation gas refers to gas released from the intestines, and for example, defecation gas includes gases that are released simultaneously with defecation and gases that are not released simultaneously with defecation.

[0084] (Evaluation and estimation of fecal gas using a control device) This section describes the evaluation and estimation process of the user's defecation gas by the control device 223 of the toilet seat device 200. The control device 223 performs estimation processing using the gas information detected by the second detection unit 222. The control device 223 calculates various information related to the gas, for example. The control device 223 calculates values ​​based on the measured values ​​measured by the second detection unit 222. The control device 223 calculates the resistance value of the sensor element based on the voltage value measured by the gas sensor 240. For example, the control device 223 calculates the resistance value of the sensor element from the measured voltage value using a function that shows the relationship between the voltage value and the resistance value of the sensor element.

[0085] The control device 223 calculates the amount or concentration of gas based on the calculated resistance value of the sensor element. The control device 223 estimates (calculates) the amount or concentration of gas from the calculated resistance value using a function (gas estimation function) that shows the relationship between the resistance value and the amount or concentration of gas. For example, the control device 223 may calculate the amount or concentration of gas related to the intestinal environment from the change in the sensor data detected by the second detection unit 222 from the baseline (e.g., the voltage value before measuring fecal gas). In this case, the control device 223 may convert the amount or concentration of gas into a unique index (e.g., an intestinal environment index) and generate information showing changes over time.

[0086] The control device 223 estimates an evaluation of the intestinal environment (also called "evaluation of defecation gas") using the amount or concentration of gas detected by the second detection unit 222. For example, the control device 223 estimates the evaluation of defecation gas based on the amount or concentration of defecation gas as biological information. For example, the control device 223 estimates biological information using an evaluation estimation function that takes the amount or concentration of gas detected by the second detection unit 222 as input and outputs an evaluation of defecation gas.

[0087] If the control device 223 can detect a gas (also called "odorless gas") that indicates a higher likelihood of a healthy intestinal environment when its quantity or concentration is high, it uses the quantity or concentration of the odorless gas to estimate the fecal gas evaluation. For example, the control device 223 estimates a higher fecal gas evaluation when the quantity or concentration of the odorless gas is high. The control device 223 estimates (calculates) the fecal gas evaluation using a gas estimation function that increases the value of the fecal gas evaluation when the quantity or concentration of the odorless gas is high.

[0088] If the control device 223 can detect gases (also called "odorous gases") that indicate a high probability of a poor intestinal environment when their quantity or concentration is high, it estimates the fecal gas evaluation using the quantity or concentration of the odorous gas. For example, the control device 223 estimates a lower fecal gas evaluation when the quantity or concentration of odorous gas is high. The control device 223 estimates the fecal gas evaluation using a gas estimation function that reduces the value of the fecal gas evaluation when the quantity or concentration of odorous gas is high.

[0089] The above is merely an example, and the control device 223 may estimate the evaluation of fecal gas in any manner. For example, the control device 223 may estimate the evaluation of fecal gas based on the amount or concentration of odorless gas and the amount or concentration of odorous gas in the user's fecal gas. The control device 223 estimates a higher evaluation of fecal gas the greater the amount of odorless gas in the user's fecal gas compared to the amount or concentration of odorous gas, based on the amount or concentration of odorless gas and the amount or concentration of odorous gas in the fecal gas. The control device 223 estimates a lower evaluation of fecal gas the greater the amount of odorous gas in the user's fecal gas compared to the amount of odorless gas, based on the amount or concentration of odorless gas and the amount or concentration of odorous gas in the fecal gas. The above is merely an example, and the control device 223 may perform any estimation based on the calculated index.

[0090] (An example of a process for detecting fecal gas) Next, an example of the detection of defecation gas by the second detection unit 222 will be described. Below, the specific operation of the method for acquiring gas information by the second detection unit 222 will be described. Figure 6 is a diagram showing an example of the process performed by the toilet seat device according to the embodiment.

[0091] First, an example of a gas sensor 240 in the toilet seat device 200 will be described. The second detection unit 222 has a gas sensor 240 that detects gases indicating the user's intestinal environment. For example, the gas sensor 240 may be a gas sensor (also called an "odor gas sensor") capable of detecting gases (odorous gases) that indicate poor health due to intestinal putrefaction. For example, odorous gases are gases produced by putrefaction by harmful bacteria in the intestines. For example, odorous gases may be gases containing sulfur components among fecal gases. Examples of odorous gases include ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, indole, skatole, etc.

[0092] Furthermore, the second detection unit 222 may have multiple gas sensors 240, including gas sensors (also called "odorless gas sensors") capable of detecting gases (odorless gases) that originate from intestinal fermentation and indicate a high level of health, in addition to odorous gases. For example, odorless gases are gases produced by fermentation by beneficial bacteria in the intestines. For example, odorless gases may be gases that originate from intestinal fermentation and increase in quantity as the health of the intestines improves. Examples of odorless gases include hydrogen, carbon dioxide, acetic acid, methane, ethanol, and water.

[0093] The second detection unit 222 may have multiple gas sensors 240. For example, the second detection unit 222 may be a hydrogen gas sensor and may include multiple gas sensors 240 such as an odor gas sensor and a methane gas sensor.

[0094] For example, the toilet seat device 200 may detect (estimate) the amount or concentration of odorous gas by subtracting the influence of the amount or concentration of odorless gas detected by the second detection unit 222 from the amount or concentration of odorous gas detected by the second detection unit 222.

[0095] Next, an example of a gas sensor configuration will be explained using Figure 7. Figure 7 is a diagram showing an example of a gas sensor configuration. Specifically, Figure 7 is a diagram showing an example of the CR circuit configuration of a semiconductor type gas sensor 240.

[0096] The gas sensor 240 consists of a sensor element and a measuring resistor. In Figure 8, the gas sensor 240 has a circuit configuration CR in which the sensor element (corresponding to the sensor resistor RS in Figure 7) and the measuring resistor (corresponding to the resistor RL in Figure 7) are connected in series.

[0097] In the semiconductor gas sensor 240, a value related to the gas amount is calculated using the following equation (1). Equation (1) corresponds to the circuit configuration CR shown in Figure 7 and is the same equation as the function FC1 in Figure 7.

[0098] RS =((Vc-Vout) / Vout)×RL… (1)

[0099] In equation (1), "RS" represents the resistance value of the sensor element. For example, "RS" in equation (1) represents the resistance value of the sensor resistance RS, which is an example of a value calculated based on measurements by the gas sensor 240. Thus, equation (1) is a formula for calculating resistance values.

[0100] In equation (1), "RL" represents the resistance value of the resistive element RL. In equation (1), "Vc" represents the voltage value of the circuit voltage Vc. In equation (1), "Vout" represents the voltage value of the output voltage Vout at the resistive element. For example, "Vout" in equation (1) represents the voltage value of the resistive element RL, which is an example of a measurement value measured by the gas sensor 240.

[0101] The resistance value of the sensor resistance RS in equation (1) is an indicator related to the amount or concentration of fecal gas. The toilet seat device 200 calculates an indicator (resistance value) related to the amount or concentration of fecal gas from the measured value (voltage value), and calculates the amount of gas from the calculated resistance value. A detailed explanation of the principle of semiconductor gas sensors is omitted, but for example, in the circuit configuration CR in Figure 7, "RH" corresponds to a heater (resistor) for heating the sensor element, and "V" corresponds to a heater (resistor) for heating the sensor element. H This corresponds to the heater voltage. Note that the gas sensor in this invention is not limited to a semiconductor type sensor; any sensor satisfying the above formula (1) can be used as a substitute.

[0102] The above is merely an example, and the second detection unit 222 may have any gas sensor of any type, not limited to those described above. For example, the second detection unit 222 may have a gas sensor such as an infrared CO2 sensor (carbon dioxide concentration meter). Furthermore, the second detection unit 222 may have multiple types or multiple gas sensors of any type. For example, the second detection unit 222 may have an electrochemical gas sensor in addition to an infrared CO2 sensor.

[0103] (An example of how to estimate the effects of fecal gas) Next, an example of estimation processing based on the detection of fecal gas by the second detection unit 222 will be described. The control device 223 performs the estimation processing shown below. Note that explanations of points that are the same as those described above will be omitted as appropriate.

[0104] The control device 223 estimates the amount or concentration of gas used to estimate the evaluation of fecal gas based on the detection of fecal gas by the second detection unit 222. As shown in Figure 6, the control device 223 estimates the amount or concentration of gas X (e.g., odorous gas) used to estimate the evaluation of fecal gas from the calculated resistance value using a function (gas estimation function) that shows the relationship between the resistance value and the amount or concentration of gas X.

[0105] The control device 223 then uses an evaluation estimation function that takes the estimated amount or concentration of gas X as input and outputs an evaluation of the stool gas to estimate the stool gas evaluation as biological information. In Figure 6, the control device 223 estimates a value indicated by ● in the time-series data based on the stool gas detection information (also called the "intestinal environment index") as the stool gas evaluation, based on the estimated amount or concentration of gas X. For example, the time-series data is from one month ago (1M ago) to the day of processing and is information about the intestinal environment (evaluation of stool gas).

[0106] Through the series of processes described above, the toilet seat device 200 can measure the contents of the user's stool gas and then use an evaluation function that outputs an evaluation of the stool gas to estimate an intestinal environment index that indicates the state of the user's intestinal environment.

[0107] (Example of information display on a display device) From here, assuming the processing described above, an example of information provided to the user by the toilet system 10 will be explained. For example, the toilet system 10 generates various types of information as shown below and displays the generated information on the corresponding user's display device 100. For example, the user's display device 100 has a gut health app installed for health management that displays information related to the user's health, and the gut health app displays various types of information related to the user's health. Below, an example of the information displayed on the display device 100 by the gut health app will be explained in order.

[0108] Figure 8 shows an example of a home screen displayed by the display device according to the embodiment. When a user taps (selects) a gut health app installed on the display device 100, for example, the display device 100 displays a home screen as shown in Figure 8. As shown in Figure 8, the home screen displays information such as the gut environment index described later, a "gut rank" that indicates the user's gut condition as a rank based on the gut environment index, an explanation of the gut rank, and buttons to display advice on how to improve the gut rank.

[0109] Figure 9 shows an example of a gut microbiome graph displayed by the display device according to the embodiment. Figure 9 shows an example of a gut microbiome graph displayed when the user taps the "Gut Microbiome" button on the home screen. In Figure 9, the vertical axis represents gut microbiome indicators and the horizontal axis represents the date, showing a line graph that represents the change in estimated values ​​of gut microbiome indicators from one month ago (February 1st) to today (March 1st). For example, the results of the line graph shown in Figure 9 show a trend of improvement in the user's gut microbiome indicators.

[0110] The dotted line in the graph indicating "Your Reference Value" represents the reference value set for each user, as will be explained later.

[0111] Figure 10 shows an example of the intestinal environment deviation score displayed by the display device according to the embodiment. In Figure 10, the deviation score of the user's intestinal environment index is shown compared to all other users. For example, from Figure 10, it can be seen that the deviation score of the user's intestinal environment index compared to all other users is "54", and the intestinal environment rank is 30,511th out of 103,322 people.

[0112] Figure 11 shows an example of the intestinal environment deviation score displayed by the display device according to the embodiment. In Figure 11, the intestinal environment deviation score shown in Figure 10 is shown, reflecting the user's gender and age. In Figure 11, the deviation score of the user's intestinal environment index is shown among other users of the same gender and age. For example, from Figure 11, it can be seen that the deviation score of the user's intestinal environment index for a male in his 50s is "59", and his intestinal environment ranking is 8324th out of 48344 people.

[0113] Figures 12 to 16 show examples of intestinal environment graphs displayed by the display device according to the embodiment. Figures 12 to 16 show examples of displays when the graph display parameters are changed for the intestinal environment graph shown in Figure 9.

[0114] For example, as shown in Figure 12, the display device 100 displays a graph of the intestinal environment from one month ago (February 1, 2024) to today (March 1, 2024) via a transition from the home screen. Here, the user changes the display period to three months ago (December 1, 2023) to today (March 1, 2024) by entering the new period in the display period input field. In this case, as shown in Figure 13, the display device 100 displays a graph of the intestinal environment with the display period changed to three months ago (December 1, 2023) to today (March 1, 2024). Here, the user changes the display period to seven months ago (August 1, 2023) to today (March 1, 2024) by entering the new period in the display period input field. In this case, the display device 100 displays an intestinal environment graph with the display period changed from seven months ago (August 1, 2023) to today (March 1, 2024), as shown in Figure 14.

[0115] Furthermore, in addition to changing the horizontal axis parameter related to the display period, the display device 100 can also change the vertical axis parameter that shows the intestinal environment indicators. For example, as shown in Figure 15, if the user selects "Overall Graph," the display device 100 displays the user's intestinal environment graph, with the intestinal environment indicators corresponding to the "Overall Graph." On the other hand, as shown in Figure 16, if the user selects "Your Graph," the display device 100 displays the user's intestinal environment graph, with the intestinal environment indicators corresponding to "Your Graph." In other words, the display device 100 can display an intestinal environment graph with a magnification of the intestinal environment indicators corresponding to the selection made by the user, either "Overall Graph" or "Your Graph."

[0116] Here, for example, in the "Overall Graph," the vertical axis of the intestinal environment graph is set to display values ​​from 1 to 7, which are predetermined values, whereas in the "Your Graph," the vertical axis is set to display values ​​within a range from "minimum value + predetermined margin" to "maximum value + predetermined margin" during the display period. As a result, the display device 100 can display the intestinal environment graph for "Your Graph" at a higher magnification than the "Overall Graph."

[0117] [First Embodiment] (overview) Now, having described the common elements of the toilet system 10 according to the first to third embodiments, the following will explain the processing details of each embodiment in order, based on the aforementioned information.

[0118] Conventionally, toilet seat devices equipped with gas sensors capable of detecting flatulence (fecal gas) expelled simultaneously with feces are known (see, for example, Patent Documents 1 and 2). The toilet seat device described in Patent Document 1 has a hydrogen gas sensor capable of mainly detecting hydrogen and a hydrogen sulfide gas sensor capable of mainly detecting hydrogen sulfide, and is capable of acquiring biometric information regarding the user's health status based on fecal gas. On the other hand, people have inferred the state of their intestinal environment and decided whether or not they need to change their lifestyle behavior by visually observing the shape of their excrement or subjectively evaluating the condition of their stomach.

[0119] Research by the inventors has revealed that the temporal changes in odorless gases (composed of hydrogen, ethanol, water, carbon dioxide, acetic acid, methane, etc.) and odorous gases (composed of ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, indole, skatole, etc.) contained in flatulence (fecal gas) released during defecation indirectly reflect the temporal changes in the intestinal environment. The intestinal environment is known to change in response to changes in diet and exercise levels, and accurately estimating the state of the intestinal environment can encourage improvements in the lives of toilet users. Therefore, it is important to measure the components of fecal gas more accurately, and the inventors have been improving these methods through various hardware innovations.

[0120] Conventional technology has made it possible to visualize the general state of the intestinal environment as it changes due to the user's diet and lifestyle, and users can now visually see the data on the general state of the intestinal environment (intestinal environment indicators) obtained from this device. However, the intestinal environment indicators derived from stool gas are a new concept, and there is a problem in that it is difficult for users to interpret whether the values ​​are good or bad.

[0121] Therefore, the toilet system 10A according to the first embodiment includes a storage means for storing defecation gas data acquired in the toilet space together with personal identification information and date and time information, a user operation means for receiving user operations, and a data display means for displaying a time-series information screen that divides the defecation gas data for a specified period set by the user operations received by the user operation means into time-series data, wherein the data display means displays the results of evaluating the defecation gas data on the time-series information screen using a first indicator and a second indicator, the first indicator being an indicator for evaluating defecation gas data based on a predetermined first criterion, and the second indicator being an indicator for evaluating defecation gas data based on a second criterion different from the first criterion.

[0122] For example, the toilet system 10A acquires information to identify the user (person using the toilet) who is defecating using the toilet bowl 207, through a toilet seat device 200 that functions in the toilet space. In addition, the toilet system 10A acquires data on the user's defecation gas when they defecate, through a second detection unit 222 of the toilet seat device 200.

[0123] The toilet system 10A then stores, for example, the acquired personal identification information and defecation gas data along with date and time information. The toilet system 10A then evaluates the defecation gas data by displaying the intestinal environment graph, which is shown on the time-series information screen, using a first indicator, which is a pre-set, unchanging indicator, and a second indicator, which shows statistical values ​​for multiple users and changes dynamically, according to the specified period setting of the intestinal environment graph related to the intestinal health app installed on the display device 100.

[0124] Here, we will describe the intestinal environment graph displayed by the toilet system 10A. Figure 17 is a diagram showing an example of the display content of the display device according to the first embodiment. Figure 17 shows an example of an intestinal environment graph evaluated using the first and second indicators. As shown in Figure 17, the toilet system 10A evaluates the defecation gas data using absolute evaluation by displaying the first evaluation axis (first indicator), which is an intestinal environment index calculated by substituting values ​​based on odorless gas and odorous gas into the aforementioned formula (1), on the vertical axis of the intestinal environment graph. Furthermore, the toilet system 10A evaluates the defecation gas data using relative evaluation by displaying the second evaluation axis (second indicator), which is judged based on a criterion using statistical values ​​from multiple users for the intestinal environment index, in the background of the graph.

[0125] As shown in Figure 17, the toilet system 10A clearly displays the changes in intestinal environment indicators of the stool gas data during the displayed period by showing, for example, a first evaluation axis (a numerical value from 1 to 7 on the vertical axis) which is a judgment criterion based on absolute evaluation. Furthermore, the toilet system 10A clearly displays where the stool gas data during the displayed period falls within the statistical values ​​of multiple users extracted based on the user's personal attribute information by showing a second evaluation axis (the background of the graph divided into 5 sections) which is a judgment criterion based on relative evaluation.

[0126] Using the graph shown in Figure 17 as an example, the data plotted based on the stool gas data for "February 1st" shows that the value on the first evaluation axis is around "4.3", and that it is located in the third highest evaluation range on the second evaluation axis.

[0127] As a result, the toilet system 10A can display the intestinal environment graph in an easy-to-understand manner for the user by using two indicators: a first indicator which is an absolute evaluation and can be intuitively judged by the magnitude of the numerical value, and a second indicator which is a relative evaluation and allows the user to understand the range in which they are positioned within the statistical values ​​of multiple users.

[0128] (Example configuration of display device 100A) The functional configuration of the display device 100A according to the first embodiment will be described below. Figure 18 is a block diagram showing an example of the configuration of the display device according to the first embodiment. As shown in Figure 18, the display device 100 has a communication unit 110, a control unit 120, and a storage unit 130. Note that the configuration of the display device 100 is not limited to the configuration shown in Figure 18, and other configurations are also possible as long as the desired processing can be achieved.

[0129] The communication unit 110 is implemented, for example, by a communication circuit. The communication unit 110 is connected to a predetermined network by wire or wireless and transmits and receives information with an external information processing device. For example, the communication unit 110 is connected to a predetermined network by wire or wireless and transmits and receives information with other devices such as a toilet seat device 200.

[0130] The storage unit 130 is implemented by, for example, semiconductor memory elements such as RAM (Random Access Memory) and flash memory, or storage devices such as hard disks and optical discs. For example, the storage unit 130 is a computer-readable recording medium that non-temporarily stores data used by various information processing programs, etc.

[0131] The storage unit 130 according to this embodiment stores various information necessary for processing. The storage unit 130 stores various information acquired from other devices such as various sensors. The storage unit 130 stores various information used in various information processing. For example, the storage unit 130 has a defecation gas data storage unit 131 and a personal attribute information storage unit 132.

[0132] The defecation gas data storage unit 131 stores the user's defecation gas data acquired from the toilet seat device 200. For example, the defecation gas data storage unit 131 stores the user's defecation gas data detected by the toilet seat device 200, along with personal identification information such as the ID assigned to the user and the date and time when the defecation gas data was detected.

[0133] The personal attribute information storage unit 132 stores the user's attribute information. For example, the personal attribute information storage unit 132 stores information about the user's attributes, such as gender, age, hobbies and preferences, residential area, and subjective experience information. To give a specific example, the personal attribute information storage unit 132 stores information about a user who is a man in his 30s, whose hobby is running, whose residential area is Tokyo, and whose subjective experience information from yesterday was "good".

[0134] The control unit 120 is implemented, for example, by an MPU (Micro Processing Unit) or CPU (Central Processing Unit) executing a program stored inside the display device 100A (for example, a program for various information processing related to this disclosure) using RAM or the like as a working area. Alternatively, the control unit 120 may be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).

[0135] As shown in Figure 18, the control unit 120 includes a first acquisition unit 121, a second acquisition unit 122, a user operation reception unit 123, a sensory information reception unit 124, and a data display unit 125, and realizes or executes the information processing functions and operations described below. Note that the internal configuration of the control unit 120 is not limited to the configuration shown in Figure 18, and other configurations are also acceptable as long as they perform the information processing described later.

[0136] The first acquisition unit 121 acquires defecation gas data related to defecation gas acquired by the toilet seat device 200, along with date and time information. For example, the first acquisition unit 121 acquires an evaluation value of the defecation gas estimated by the control device 223 in the toilet seat device 200, based on the measured value of the defecation gas detected by the second detection unit 222 in the toilet seat device 200, along with the date and time information of when the defecation gas was detected.

[0137] The second acquisition unit 122 acquires the user's personal identification information. For example, when the second acquisition unit 122 acquires defecation gas data from the toilet seat device 200, it acquires the user's personal identification information linked to the defecation gas data. Here, personal identification information refers to information such as an ID assigned to each user of the gut health app to uniquely identify them, and includes information such as a number registered when the gut health app was installed, or the serial number of the display device 100 owned by the user.

[0138] The user operation reception unit 123 receives information about the user's operations on the gut health app. For example, when the user uses the gut health app to display the gut environment graph, the user operation reception unit 123 receives the user's setting for the display period of the gut environment graph (see Figures 14 to 16).

[0139] The sensory information receiving unit 124 receives sensory information from the user. For example, the sensory information receiving unit 124 receives information from the user evaluating their perceived physical condition (good / bad / average) and stores it in the storage unit 130 in association with the acquired defecation gas data.

[0140] The data display unit 125 displays a time-series information screen that divides the stool gas data for a specified period into time series, as set by the user operation received by the user operation reception unit 123. For example, when a user uses the gut health app and selects a button to transition to a screen that displays a gut environment graph, the data display unit 125 generates and displays a time-series information screen using the user's stool gas data for the specified period set by the user operation, showing a graph with gut environment indicators on the vertical axis and dates on the horizontal axis. The specified period mentioned above may be set as an initial setting, or it may be set by the user through screen operations each time. The time-series information screen mentioned above may be a screen that displays the changes in the gut environment graph over the specified period in a chart format, or it may be a screen that displays the change from the previous time (increase, decrease, etc.) in a table arranged in chronological order. The following describes examples of the time-series information screen displayed by the data display unit 125.

[0141] For example, the data display unit 125 displays a first evaluation axis (first indicator) on the vertical axis of the time-series information screen, which uses a first criterion, an intestinal environment index calculated by substituting values ​​based on odorless gas and odorous gas into the aforementioned formula (1). In addition, the data display unit 125 displays a second evaluation axis (second indicator) on the background of the graph on the time-series information screen, which is judged based on a second criterion using statistical values ​​from multiple users for the intestinal environment index.

[0142] The first criterion used by the data display unit 125 has multiple evaluation levels divided into predetermined numerical values, and the second criterion has multiple evaluation levels divided into ranges different from those of the first criterion. The first criterion may also be set to have multiple evaluation levels divided into predetermined numerical ranges, similar to the second criterion, but the ranges of the evaluation levels of the first criterion and the evaluation levels of the second criterion shall be different.

[0143] As shown in Figure 17, the data display unit 125 displays, for example, the gut environment graph shown on the time-series information screen, the numerical value of the gut environment index on the vertical axis in an evaluation level from 1 to 7, displaying a first index where a higher numerical value indicates a better gut environment. The data display unit 125 also generates evaluation levels for the gut environment graph shown on the time-series information screen by dividing the background into five sections at intervals different from the numerical values ​​of the first index from 1 to 7, and displays a second index where the upper range of the graph indicates a better gut environment compared to other users.

[0144] Here, the second criterion used for the second indicator displayed by the data display unit 125 is determined based on the user's personal attribute information. For example, the second criterion uses the user's personal attribute information, such as gender, age, and place of residence, to determine the number of divisions in the graph data and the division range of the graph data.

[0145] Furthermore, the second criterion used for the second indicator displayed by the data display unit 125 is determined based on the defecation gas data of multiple users similar to the user's personal attribute information. For example, the second criterion uses statistical information based on the defecation gas data of other users whose personal identification information, such as gender, age, and place of residence, is similar to that of the user, and the division width, number of divisions, and division range of the graph data are determined. To explain with a specific example, if the user is a male in his 50s, the second criterion is determined using statistical information generated using the defecation gas data of other users who meet the criteria of being a male in his 50s.

[0146] Here, the second indicator (second evaluation axis) provided by the data display unit 125 will be explained. Figure 19 is a diagram showing an example of how to set the second evaluation axis according to the first embodiment. In Figure 19, two methods are shown as examples of second criteria for setting the second indicator: dividing the graph data into five parts by cumulative frequency (1) and dividing the graph data into five parts equally (2), based on statistical information generated by aggregating the defecation gas data of other users.

[0147] As shown in Figure 19(1), the data display unit 125 generates a histogram using the stool gas data of all users of the gut health app, with the vertical axis representing the "gut environment index" and the horizontal axis representing the "frequency of occurrence" corresponding to the number of people. The data display unit 125 then identifies values ​​corresponding to a second criterion, with ranges of 20%, 40%, 60%, and 80% set for the cumulative frequency (%), and divides the graph data into five sections at the identified points. This allows the data display unit 125 to display evaluation levels divided into ranges different from the gut environment index, based on statistical information calculated using the stool gas data of other users.

[0148] Furthermore, as shown in Figure 19(2), the data display unit 125 can also divide the graph data into five equal parts, regardless of the measured frequency, for the range of "intestinal environment indicators" for which the frequency of occurrence has been measured.

[0149] As a result, the data display unit 125 can evaluate the state of the user's intestinal environment using a second indicator, whose division range and number of divisions vary according to the stool gas data of other users that are included in the statistics, unlike the first indicator, which is a numerical value of the intestinal environment index that is a preset absolute evaluation.

[0150] For example, the data display unit 125 updates the second indicator when the user's personal attribute information changes. For instance, if the user's personal attribute information is changed from male in his 30s to male in his 40s, the data display unit 125 updates the division width to the determined value using statistical data that includes the changed male in his 40s, and displays the second indicator.

[0151] Here, we will explain the process of updating the second indicator due to changes in personal attribute information. Figure 20 is a diagram showing an example of the process by which the second evaluation axis is updated according to the personal attribute information according to the first embodiment. Figure 20 shows an example in which the information is updated from graph display (1) to graph display (2) due to changes in personal attribute information.

[0152] As shown in Figure 20, the data display unit 125 displays graph data (1) based on a second indicator determined, for example, based on the previously set personal attribute information, such as a male in his 30s. The data display unit 125 then receives notification that the personal attribute information has been changed from a male in his 30s to a male in his 40s due to user operation. The data display unit 125 then displays graph data (2) based on a second indicator determined using statistical information targeting other users who match the changed personal attribute information of a male in his 40s.

[0153] Furthermore, the data display unit 125 displays reference values ​​based on the user's past bowel gas data or set by the user. To give a specific example, the data display unit 125 generates reference values ​​such as the arithmetic mean or geometric mean of the average or median of intestinal environment indicators calculated from the user's bowel gas data acquired over a period of two weeks or more, which is displayed on the display screen, and displays the reference values ​​set in the intestinal environment graph.

[0154] Furthermore, the data display unit 125 displays reference values ​​set based on the subjective information received by the subjective information receiving unit 124. To explain with a specific example, the data display unit 125 sets the arithmetic mean or geometric mean, such as the average or median, of only the gut environment indicators when the subjective information entered by the user is "good," as reference values, and displays the generated reference values ​​on the gut environment graph.

[0155] Here, we will explain an example of how the above-mentioned reference values ​​are displayed on the gut environment graph. Figure 21 is a diagram showing an example of the process of displaying the reference values ​​on a graph according to the first embodiment. Figure 21 shows an example of how the reference values ​​are displayed as dotted lines on the gut environment graph. As shown in Figure 21, the data display unit 125 can display the user's own reference values, calculated from past gut environment indicator data, as dotted lines on the gut environment graph. As shown in the display content of Figure 21, many gut environment indicators were close to the reference values ​​during the period from February 1st to March 1st, but after March 1st, many gut environment indicators with values ​​significantly higher than the reference values ​​were recorded, indicating that the state of the gut environment has improved compared to the criteria set by the user's own information.

[0156] (Example of information display on a display device) Next, we will describe examples of information displayed on the screen when each of the processing contents of the display device 100A described above is performed. Figure 22 is a diagram showing an example of an intestinal environment graph displayed by the display device according to the first embodiment. Figure 22 shows an example of the screen displayed on the intestinal environment graph in the intestinal health app when each of the processing contents described above is performed.

[0157] As shown in Figure 22, the display device 100A displays a first indicator showing an evaluation level from "1 to 7" in the intestinal environment graph, and a second indicator showing a different evaluation level from the first indicator by dividing the background into five sections. The display device 100A then displays a baseline value calculated from the user's past intestinal environment indicator values ​​as "Your target value" using a dotted line.

[0158] As a result, the display device 100A can display the intestinal environment graph in an easy-to-understand manner for the user by using a first indicator, which is an absolute evaluation and can be intuitively judged by the magnitude of the numerical value, and a second indicator, which is a relative evaluation and allows the user to understand the range in which they are positioned within the statistical values ​​of multiple users, or by displaying a user-specific standard value calculated from the user's past intestinal environment indicators.

[0159] (Example of processing flow) From here, the flow of various processes will be explained based on the flowchart. Figure 23 is a flowchart showing an example of the process flow performed by the display device according to the first embodiment. Note that each step in the flowchart shown in Figure 23 can be executed in a different order, and additional processes may be added or omitted.

[0160] First, the display device 100A acquires the defecation gas data acquired by the toilet seat device 200 along with date and time information (S101). Then, the display device 100A acquires personal identification information associated with the defecation gas data (S102). Next, the display device 100A accepts a specified period that indicates the display range of the intestinal environment graph set by the user (S103). Finally, the display device 100A displays a time-series information screen that evaluates the defecation gas data for the specified period using the first and second indicators (S104), and then the process ends.

[0161] [Second Embodiment] (overview) Next, a toilet system 10B according to the second embodiment will be described. In the first embodiment described above, a process was described for displaying an intestinal environment graph in which defecation gas data over a specified period was evaluated using a first indicator and a second indicator. In the second embodiment, a process will be described for displaying lifestyle information, which is past behavior that is considered to have an impact on the user's intestinal environment, along with the intestinal environment graph. The lifestyle information broadly includes information about the content of everyday life activities such as diet, exercise, and sleep, but does not include the defecation gas data used to generate the intestinal environment graph described above.

[0162] Conventional technology made it possible to visualize the general state of the gut environment as it changed due to the user's diet and lifestyle. Users could then link the data on the general state of the gut environment obtained from this device with their own entered lifestyle logs, allowing them to review their past lifestyle behaviors with the results. However, the gut environment does not change due to a single meal or lifestyle action, but rather changes over several weeks as these actions become habitual and have a continuous impact. Therefore, when reviewing lifestyle behaviors, it is desirable to review logs over multiple days rather than just a single day.

[0163] Therefore, the toilet system 10B according to the second embodiment comprises: a first acquisition means for acquiring defecation gas data related to defecation gas acquired in the toilet space along with date and time information; a second acquisition means for acquiring personal identification information; a third acquisition means for acquiring user lifestyle information that matches the personal identification information; a storage unit for storing defecation gas data and user lifestyle information; a user operation means for receiving user operations on an operation terminal operated by the user; and a data display means for displaying a time-series information screen that divides the defecation gas data for a specified period set by the user operation into time-series information, wherein the data display means displays lifestyle information stored during a predetermined period either within the specified period or before or after the specified period, along with the time-series information screen for the specified period.

[0164] For example, the toilet system 10B acquires information to identify the user (person using the toilet) who is defecating using the toilet bowl 207, through a toilet seat device 200 that functions in the toilet space. In addition, the toilet system 10B acquires data on the user's defecation gas when they defecate, through a second detection unit 222 of the toilet seat device 200.

[0165] The toilet system 10B then receives lifestyle information, such as the user's eating, exercise, and sleep history, for users whose personal identification information has been acquired. The toilet system 10B then stores the acquired defecation gas data, personal identification information, and lifestyle information as a single data set. The toilet system 10B then displays the lifestyle information within or around the specified period, along with the gut environment graph displayed on the time-series information screen, according to the specified period setting for the gut health app installed on the display device 100B.

[0166] Here, we will describe the intestinal environment graph displayed by the toilet system 10B. Figure 24 is a diagram showing an example of the processing content of the display device according to the second embodiment. Figure 24 shows an example of the processing of displaying lifestyle information within the specified period for displaying the intestinal environment graph. As shown in Figure 24, the toilet system 10B displays lifestyle information indicating the user's diet at a predetermined position in the intestinal environment graph, corresponding to the dates and times of intake, from March 1 to March 15, for the specified period from February 1 to March 15, as evaluated by the first and second indicators according to the first embodiment described above.

[0167] As a result, the toilet system 10B can display the intestinal environment graph in a way that correlates the time-series changes in the intestinal environment with past lifestyle behaviors, by displaying past behaviors that are considered to have influenced the user's intestinal environment during and around the display period, along with a line graph showing the trend of intestinal environment indicators.

[0168] (Example configuration of display device 100B) The functional configuration of the display device 100B according to the second embodiment will be described below. Figure 25 is a block diagram showing an example of the configuration of the display device according to the second embodiment. As shown in Figure 25, the display device 100B has a communication unit 110, a control unit 120, and a storage unit 130. Note that the configuration of the display device 100B is not limited to the configuration shown in Figure 25, and other configurations are also possible as long as the desired processing can be achieved. In addition, in the following description, processing content that is common with the processing content of the first embodiment described above will be omitted.

[0169] The lifestyle information storage unit 133 stores the user's lifestyle information. For example, the lifestyle information storage unit 133 stores the user's past dietary history, exercise habits, sleep habits, and other lifestyle information entered using the gut health app through user operation, along with the corresponding date and time information.

[0170] The third acquisition unit 126 acquires user lifestyle information that matches the personal identification information. For example, the third acquisition unit 126 acquires lifestyle information, which is the user's life history, for users whose personal identification information has been acquired by the toilet seat device 200 when acquiring defecation gas data. Here, lifestyle information refers to any behavioral history that is considered to have an effect on the state of the intestinal environment, including, for example, information on diet, exercise, and sleep. The third acquisition unit 126 also acquires the content of the user's lifestyle information input by receiving user operations on the lifestyle information input screen according to the third embodiment described later.

[0171] To illustrate with a specific example, the third acquisition unit 126 acquires the user's lifestyle history, such as consuming lactic acid bacteria beverage X on February 1st, performing yoga for two hours on February 2nd, and sleeping for six hours on February 3rd, and stores this information in the lifestyle information storage unit 133. Furthermore, the third acquisition unit 126 includes lifestyle information related to diet, including information on the products, amounts, and duration of consumption of either probiotics or prebiotics, or both.

[0172] Here, probiotics refer to live microorganisms that have a positive effect on the host's health by improving the balance of the gut flora, and are mainly lactic acid bacteria and bifidobacteria, which are found in abundance in yogurt and fermented foods. It is said that directly ingesting beneficial bacteria such as probiotics from food improves the intestinal environment and has various health effects. Prebiotics, on the other hand, refer to indigestible food components that have a beneficial effect on the host and improve the host's health by selectively altering the growth and activity of specific bacteria in the large intestine, and are mainly oligosaccharides and dietary fiber, which are found in abundance in apples and oatmeal.

[0173] The user operation reception unit 123 accepts the selection of at least one piece of lifestyle information stored in the lifestyle information storage unit 133. For example, on the screen for setting the content of lifestyle information displayed by the gut health app, the user operation reception unit 123 accepts the selection of lifestyle information that has been acquired in the past.

[0174] The identification unit 127 identifies a group of users whose personal attribute information and / or defecation gas data match either or both of the personal attribute information and / or defecation gas data selected by the user operation reception unit 123. For example, the identification unit 127 uses the settings for other users' personal attribute information and defecation gas data received on a screen in the gut health app where users' lifestyle information is set, to identify a group of other users from among multiple other users stored in the cloud server 300 whose settings match the settings.

[0175] To explain with a specific example, when the specific unit 127 receives personal attribute information such as "male in his 30s" and defecation gas data such as "intestinal environment index of 4 or higher for the past two weeks" from a user in the intestinal health app, it identifies a group of users from among multiple users whose data is stored in the cloud server 300 that match the settings of "male in his 30s" and "intestinal environment index of 4 or higher for the past two weeks".

[0176] The extraction unit 128 extracts lifestyle information and defecation gas data for the user group identified by the identification unit 127. For example, for each of the other users included in the user group identified by the identification unit 127, the extraction unit 128 extracts lifestyle information such as dietary content and exercise time, as well as defecation gas data such as gut environment graphs and numerical information of gut environment indicators, stored in association with the other users, from the cloud server 300.

[0177] The data display unit 125 displays lifestyle information stored during a predetermined period, either within the specified period or before or after it, along with a time-series information screen for the specified period. For example, the data display unit 125 displays lifestyle information corresponding to the period within or before / after the specified period, along with a gut microbiome graph, for the display period received by the user operation reception unit 123.

[0178] Here, we will explain how the lifestyle information displayed by the data display unit 125 is displayed. Figure 26 is a diagram showing an example of the process of displaying lifestyle information in the intestinal environment graph according to the second embodiment. Figure 26 shows an example of how lifestyle information is displayed in the intestinal environment graph.

[0179] As shown in Figure 26, the data display unit 125 first displays a gut environment graph corresponding to the display period from one month ago (February 1st) to today (March 1st), which was received by the user operation reception unit 123. Then, for lifestyle information that has continued for two weeks or more up to today (March 1st), the data display unit 125 indicates the period of implementation of the lifestyle information with an arrow at the bottom of the gut environment graph, and indicates the content of the lifestyle information with "**** (words representing the content of the lifestyle information)".

[0180] Figure 27 shows an example of a process for displaying multiple types of lifestyle information on an intestinal environment graph according to the second embodiment. Figure 27 shows an example of displaying multiple types of lifestyle information outside of the intestinal environment graph. As shown in Figure 27, the data display unit 125 displays "Dietary Information****" and "Exercise Information****" below the display area of ​​the intestinal environment graph, similar to Figure 26, thereby displaying lifestyle information together with the intestinal environment graph. In the example of Figure 27, only the content of the lifestyle information related to the display period is displayed in "****", but this is not limited to this, and for example, the period during which the lifestyle information was implemented may be included in "****" (for example, from February 1st to March 1st).

[0181] Furthermore, the data display unit 125 displays a message indicating that the defecation gas data for a specified period consistently meets predetermined conditions. For example, the data display unit 125 determines that the intestinal environment index is high if, for the intestinal environment graph for a display period set by the user, the percentage of days in which the intestinal environment index value is higher than the previous day is above a certain level, or if the intestinal environment value rises above a certain level. The data display unit 125 then generates a comment indicating that the intestinal environment index is high and displays it together with the intestinal environment graph.

[0182] Here, we will describe the screen displayed by the data display unit 125 in the process described above. Figure 28 is a diagram showing an example of the process that displays that the intestinal environment is good according to the second embodiment. Figure 28 shows an example of displaying a comment indicating that the user's intestinal environment indicators are high.

[0183] As shown in Figure 28(1), the data display unit 125 calculates the number of days on which the gut environment index increased and decreased compared to the previous day, for the period from today to one week prior, which is included in the display period of the gut environment graph displayed from one month ago (February 1) to today (March 1). The data display unit 125 then calculates that the number of days on which the gut environment index increased is 6 days and the number of days on which it decreased is 1 day, and determines that the user's gut environment index has increased because the number of days on which the gut environment index increased is more than twice the number of days on which it decreased. The data display unit 125 then generates the comment "Your gut environment index is high!" along with an arrow indicating that the gut environment index has increased, and displays it on the screen along with the gut environment graph.

[0184] Furthermore, as shown in Figure 28(2), the data display unit 125 can also determine that the user's gut environment index has increased if the difference between the gut environment index for today (March 1) and the minimum value of the gut environment index within the display period from one month ago (February 1) to today (March 1) is greater than or equal to a certain value.

[0185] In addition, the processing example of the data display unit 125 described above explains the case when the gut environment indicator is high, but it is not limited to this. For example, if the percentage of gut environment indicators that are decreasing is high, or if the difference between the most recent day and the maximum value of the gut environment indicator within the display period is above a certain value, the system can determine that the gut environment indicator is low and display a comment to that effect.

[0186] Furthermore, if the defecation gas data for the specified period continues to meet predetermined conditions, the data display unit 125 recommends and displays lifestyle information stored during either the specified period or the period preceding the specified period as lifestyle information suitable for the user. For example, the data display unit 125 extracts the period in the intestinal environment graph for the displayed period in which the intestinal environment index exceeds the standard value according to the first embodiment, and identifies the lifestyle information stored in association with that period as lifestyle information suitable for the user. The data display unit 125 then generates a comment that displays the identified lifestyle information in correspondence with that period and displays it together with the intestinal environment graph.

[0187] Here, we will describe the screen displayed by the data display unit 125 in the process described above. Figure 29 is a diagram showing an example of the process of recommending for a period in which the intestinal environment is good according to the second embodiment. Figure 29 shows an example of recommending lifestyle information linked to a period in which the user's intestinal environment indicators are high.

[0188] As shown in Figure 29(1), the data display unit 125 extracts the four most recent days in which the gut environment indicators exceeded the standard value (dotted line) for the display period from one month ago (February 1) to today (March 1), as the period in which the gut environment indicators are high. The data display unit 125 then generates "****", which is lifestyle information stored in association with the stool gas data for the most recent four days, as recommendation 1. The data display unit 125 then generates and displays a screen in which the generated recommendation 1 is connected by arrows to the range of the most recent four days in the gut environment graph.

[0189] Furthermore, as shown in Figure 29(2), the data display unit 125 identifies lifestyle information "****" from two weeks prior to the most recent four days when the gut environment indicators were high, for the display period from one month ago (February 1st) to today (March 1st). The data display unit 125 then generates and displays a screen in the gut environment graph showing the period during which the identified "****" was implemented with an arrow. Generally, changes in gut environment indicators due to ingested food are said to appear about two weeks after ingestion, so the data display unit 125 can recommend lifestyle information from about two weeks prior that is considered to be a factor in the high gut environment.

[0190] Furthermore, the data display unit 125 displays a time-series screen showing the period during which the selected lifestyle information was stored. For example, the data display unit 125 generates and displays a screen showing the period associated with the lifestyle information selected by the user, as received by the user operation reception unit 123, within the intestinal environment graph.

[0191] Here, we will describe the screen displayed by the data display unit 125 in the aforementioned process. Figure 30 is a diagram showing an example of the process of displaying the period of implementation of lifestyle information on the intestinal environment graph according to the second embodiment. Figure 30 shows an example in which the intake period of "○○", which is lifestyle information selected by the user, is shown in the intestinal environment graph.

[0192] As shown in Figure 30, the data display unit 125 acquires the intake period "2 / 1~2 / 14" for the lifestyle information of "○○ intake" selected by the user. The data display unit 125 then generates and displays a screen outside the intestinal environment graph showing "○○ intake period: 2 / 1~2 / 14," and inside the intestinal environment graph an arrow representing the intake period and the words "○○ intake."

[0193] Furthermore, the data display unit 125 displays the lifestyle information extracted by the extraction unit 128, associating it with either or both of the personal attribute information and the defecation gas data. For example, the data display unit 125 generates and displays a screen showing the lifestyle information of other users extracted by the extraction unit 128, along with the other users' personal identification information and defecation gas data linked to their lifestyle information.

[0194] Here, we will describe the screen displayed by the data display unit 125 in the process described above. Figure 31 is a diagram showing an example of the process of displaying comments from similar users according to the second embodiment. Figure 31 shows an example of displaying lifestyle information of other users similar to the user's personal attribute information as comments.

[0195] As shown in Figure 31, the data display unit 125 generates and displays a screen for each other user that matches the lifestyle information of other users whose personal attribute information matches that of "women in their 30s," whose age range is adjacent to the user's personal attribute information "women in their 40s," extracted by the extraction unit 128, by associating the aforementioned gut index with the lifestyle information. To explain with a specific example, for "Ms. A," who is a woman in her 30s, the data display unit 125 displays a screen with the comment "Lactic acid bacteria beverage X is good!" which recommends lifestyle information such as the content of her diet, and the words "Gut index A" displayed as a comment.

[0196] Furthermore, the data display unit 125 can also display lifestyle information that is extracted at a high rate in the user group identified by the identification unit 127, for example, by generating a bar graph showing the extraction rate for lifestyle information for multiple users extracted by the extraction unit 128.

[0197] Furthermore, if there are multiple pieces of lifestyle information for different dates and times within a predetermined period, the data display unit 125 will display the multiple pieces of lifestyle information separately for each date and time, along with the time-series information screen. For example, if, within the display period specified by the user, the lifestyle information for meals, exercise, and sleep is stored for different implementation periods, the data display unit 125 will generate and display a screen representing the implementation period corresponding to each piece of lifestyle information.

[0198] Here, we will describe the screen displayed by the data display unit 125 in the process described above. Figure 32 is a diagram showing an example of the display mode when the intestinal environment graph and lifestyle information are displayed simultaneously according to the second embodiment. Figure 32 shows examples of the display mode when multiple types of lifestyle information are displayed in correspondence with their respective periods.

[0199] As shown in Figure 32(1), the data display unit 125 identifies the stored diet information "****", exercise information "****", and sleep information "****" associated with the date and time within the displayed period for the gut environment graph from one month ago (February 1) to today (March 1) as specified by the user. The data display unit 125 then generates and displays a screen in the gut environment graph showing the diet information "****", exercise information "****", and sleep information "****" with arrows or dots corresponding to their respective implementation periods.

[0200] Furthermore, while Figure 32(1) shows an example where lifestyle information is displayed in separate sections for each type of lifestyle information, such as diet information, exercise information, and sleep information, the data display unit 125 can also generate and display a screen corresponding to the period of implementation of the lifestyle information linked to the display period, by listing it within the intestinal environment graph, without separating the sections for each type of lifestyle information, as shown in Figure 32(2).

[0201] Furthermore, while Figure 32(1) shows an example where all three lifestyle information items—diet information, exercise information, and sleep information—are displayed within the gut environment graph, the data display unit 125 can also generate and display a screen that, as shown in Figure 32(3), displays only the diet information that has been pre-configured by the user within the gut environment graph, while hiding exercise information and sleep information that have not been configured for display within the gut environment graph.

[0202] Furthermore, the data display unit 125 updates the time-series information with the changed setting period in response to the change in the specified period. For example, when the user operation reception unit 123 receives a change in the display period specified by the user, the data display unit 125 generates and displays a screen showing the intestinal environment graph (moving average of intestinal environment indicators of stool gas data) for the changed display period.

[0203] Here, the aforementioned setting period is the period used to calculate the moving average, which is set according to the change in the specified period. To give a specific example, if the specified period (display period) is 1 month, the setting period is 7 days; if the specified period is 3 months, the setting period is 21 days; if the specified period is 6 months, the setting period is 30 days, and so on. The setting period is a period that is set in advance according to the length of the specified period and is used to calculate the moving average. The data display unit 125 then generates and displays an intestinal environment graph in which the moving average calculated from the stool gas data during the setting period is represented as a representative value for the setting period.

[0204] (Example of information display on a display device) Next, we will describe examples of information displayed on the screen when each of the processing contents of the display device 100B described above is performed. Figures 33 to 42 show examples of lifestyle information displayed by the display device according to the second embodiment.

[0205] Figure 33 shows an example of a screen displaying the user's lifestyle information history (gut health log). As shown in Figure 33, the display device 100B displays a gut environment graph, gut environment indicators, lifestyle information related to diet, and lifestyle information related to exercise for the display period from July 1, 2024 to August 1, 2024.

[0206] As shown in Figure 33, the data display unit 125 displays, outside the gut environment graph, that the gut environment index is "E" around "7 / 16", along with lifestyle information related to diet indicating that a lactic acid bacteria beverage was consumed, and lifestyle information related to exercise indicating that running was performed.

[0207] Figure 34 shows an example screen (1) displaying a gut microbiome graph for a relatively long display period "January 1, 2024 to August 1, 2024," and an example screen (2) displaying lifestyle information when the gut microbiome graph in (1) is tapped. As shown in Figure 34, when the display device 100B taps the graph near "April 1, 2024" in the gut microbiome graph for the display period "January 1, 2024 to August 1, 2024," it displays a gut microbiome graph for a relatively short display period "January 1, 2024 to May 1, 2024," and also displays lifestyle information corresponding to that period in the same way as in Figure 34. The display period can be arbitrarily set by the user.

[0208] Figure 35 shows an example screen that recommends lifestyle information to the user corresponding to the date when the user's gut microbiome index is high. As shown in Figure 35, the display device 100B displays the comment "○○ yogurt seems to be right for you!" recommending lifestyle information related to meals, "consuming ○○ yogurt," which is common to "5 / 11" and "5 / 12" where the gut microbiome index is in the A range, for the five days of display period "5 / 10 to 5 / 14".

[0209] Figure 36 shows an example screen that displays further recommended foods to the user, using the recommendation content from Figure 35. As shown in Figure 36, the display device 100B displays the top 3 most popular yogurt products in the same category as "○○ Yogurt" shown in Figure 35, along with the phrase "Recommended for you." The recommended foods to the user can be obtained, for example, from information on top-selling products acquired when searching for products in the same category on the internet.

[0210] Figure 37 shows an example screen where information is recommended to the user based on the status of the user's gut microbiome indicators. As shown in Figure 37, if the user's gut microbiome indicators remain low for a certain period of time or longer, the display device 100B determines that the user's gut microbiome indicators are low and displays the message, "Your gut microbiome indicators are showing signs of deterioration. Is your diet irregular?" along with comments such as, "The gut environment is said to be affected by diet. Water-soluble dietary fiber is said to be good!" and images of related websites and products recommended to the user.

[0211] Figure 38 shows an example screen displaying comments on social media regarding the gut health status of other users. As shown in Figure 38, the display device 100B displays buttons representing "Everyone's Gut Health," "Gut Health Related Columns," "Gut Health Event Information," "Gut Health Item Information," and "Share with Family." Below, we will sequentially explain examples of screen displays when the "Everyone's Gut Health" and "Share with Family" buttons, which are related to the processing of the display device 100B according to the second embodiment, are tapped. When "Gut Health Related Columns" is tapped, for example, a screen displaying columns related to gut health will be shown. When "Gut Health Event Information" is tapped, for example, a screen displaying information about events related to gut health (for example, events that grant rewards through in-app operations, or workshops on gut health) will be shown. When "Gut Health Item Information" is tapped, a screen displaying information about foods recommended for gut health practitioners and equipment used during exercise (yoga, etc.) will be shown.

[0212] Figure 39 shows an example of a screen that appears when a user taps "Everyone's Gut Health" on the screen shown in Figure 38. As shown in Figure 39, when "Everyone's Gut Health" is tapped, the display device 100B displays lifestyle information of other users that matches the personal attribute information of "women in their 30s" (see Figure 31) in comment format, and also displays images, videos, etc. from websites containing information related to the lifestyle information of other users.

[0213] Figure 40 shows an example screen displaying the percentage of lifestyle information extracted for user groups that match the set personal attribute information. As shown in Figure 40, when the display device 100B extracts lifestyle information for other user groups that match the set personal attribute information "women in their 30s" and the range of the gut environment index "A or B", it displays the lifestyle information with the highest extracted percentage in order.

[0214] Furthermore, as shown in Figure 40, the display device 100B displays "yogurt," "lactic acid bacteria beverages," and "yoga," which were extracted from lifestyle information of other user groups that match the criteria of "women in their 30s and having a gut environment index range of A or B," along with bar graphs showing the extraction rates.

[0215] Figure 41 shows an example of a screen displayed when a user taps the bar graph showing the extraction rate of "yogurt" as shown in Figure 40. As shown in Figure 41, when the display device 100B receives a tap from the user on the screen shown in Figure 40, it displays the top 3 most popular products in the yogurt category at the bottom of the screen. The display device 100B can also identify the top-selling products identified by searching for "yogurt" on the internet, for example, and obtain information on the identified products.

[0216] Figure 42 shows an example of the screen displayed when the user taps "Share with family" on the screen shown in Figure 38. As shown in Figure 42, when "Share with family" is tapped, the display device 100B displays the rank of the gut microbiome indicators of other users who are set as the user's family. As shown in Figure 42, the display device 100B displays that "I" is "Rank A", "Dad" is "Rank B", "A-ko" is "Rank B", and "B-o" is "Rank C". In addition, the display device 100B can also display a "→View Details" button along with the family members' gut microbiome indicator ranks, and when this button is tapped, it can transition to a screen showing the corresponding family member's gut microbiome graph and lifestyle information.

[0217] (Example of processing flow) From here, the flow of various processes will be explained based on the flowchart. Figure 43 is a flowchart of an example of the process flow performed by the display device according to the second embodiment. Note that each step in the flowchart shown in Figure 43 can be executed in a different order, and additional processes may be added or omitted.

[0218] First, the display device 100B acquires the defecation gas data acquired by the toilet seat device 200 along with date and time information (S201). Then, the display device 100B acquires personal identification information linked to the defecation gas data (S202). Next, the display device 100B acquires the user's lifestyle information that matches the personal identification information (S203). Then, the display device 100B accepts a specified period that indicates the display range of the intestinal environment graph set by the user (S204). Finally, the display device 100B displays the user's lifestyle information along with a time-series information screen that evaluates the defecation gas data for the specified period using the first and second indicators (S205), and the process ends.

[0219] [Third Embodiment] (overview) Next, a toilet system 10C according to the third embodiment will be described. In the second embodiment described above, a process was described in which lifestyle information acquired by the user's operation is displayed in correspondence with the intestinal environment graph. In the third embodiment, a process will be described in which the user inputs lifestyle information, and a screen reflecting the previous input is displayed, thereby simplifying the input operation.

[0220] Conventional technology makes it possible to visualize the general state of the intestinal environment as it changes due to the user's diet and lifestyle. Users can then link the data on the general state of the intestinal environment obtained from this device with their own entered lifestyle logs, allowing them to review their past lifestyle behaviors with the results. However, in order to identify the lifestyle habits that cause changes in the intestinal environment and to formulate improvement plans, it is essential for users to continuously record what kind of life they lead and what actions they take. However, recording lifestyle logs is often troublesome, or they are forgotten, leading to a high likelihood of missing data, or users giving up and stopping recording altogether.

[0221] Therefore, the toilet system 10C according to the third embodiment is characterized by comprising: an acquisition means for acquiring defecation gas data related to defecation gas acquired in the toilet space along with personal identification information; an input means for receiving input of user lifestyle information through user operations using the toilet space; a storage unit for storing the lifestyle information received by the input means in association with the defecation gas data; and a screen display means for displaying a lifestyle information input screen that reflects the input of lifestyle information based on user operations on the input means.

[0222] For example, the toilet system 10C acquires information to identify the user (person using the toilet) who is defecating using the toilet bowl 207, through a toilet seat device 200 that functions in the toilet space. In addition, the toilet system 10C acquires data on the user's defecation gas when they defecate, through a second detection unit 222 of the toilet seat device 200.

[0223] The toilet system 10C then receives lifestyle information, such as the user's eating, exercise, and sleep history, from a user whose personal identification information has been acquired. The toilet system 10C then stores the acquired defecation gas data, personal identification information, and lifestyle information as a single data set. The toilet system 10C then reflects the user's latest input history on the reception screen where it receives lifestyle information input from the user.

[0224] Here, we will describe the screen that accepts input of lifestyle information displayed by the toilet system 10C. Figure 44 is a diagram showing an example of the processing content of the display device according to the third embodiment. Figure 44 shows an example of the process of displaying a screen (2) that reflects the content (1) from the previous input during the current input.

[0225] As shown in Figure 44, when the toilet system 10C receives lifestyle information from the user, it displays screens for inputting first information, which represents continuous lifestyle information, and second information, which represents lifestyle information that is not continuous. In this case, the toilet system 10C can use a format in which the first information includes lifestyle information such as meals, exercise, and sleep, and the user selects from a pre-set list of options. The toilet system 10C can also use a format in which the second information includes lifestyle information that is different from the usual, such as sudden events, and the user inputs the content of the lifestyle information in text.

[0226] For example, as shown in Figure 44(1), the toilet system 10C accepts that, based on the previous input of lifestyle information, the left-hand candidate for meal information and the middle-hand candidate for exercise information (the candidate shown in bold in Figure 44) have been selected, and the second information "**** (the content of the second information input)" has been entered, and that the input content has been confirmed. Then, as shown in Figure 44(2), when the user logs into the lifestyle information input screen after the previous confirmation, the toilet system 10C displays a screen that reflects the state in which the left-hand candidate for meal information and the middle-hand candidate for exercise information (the candidate shown in bold in Figure 45), which were selected in the previous input based on the first information, have already been selected.

[0227] As a result, when the user inputs lifestyle information, the toilet system 10C reflects the information entered in the previous input when the user inputs it again. This eliminates the need to select lifestyle information related to the primary information that is continuous each time, making it easier for users to input their lifestyle logs.

[0228] (Example configuration of display device 100C) The functional configuration of the display device 100C according to the third embodiment will be described below. Figure 45 is a block diagram showing an example of the configuration of the display device according to the third embodiment. As shown in Figure 45, the display device 100C has a communication unit 110, a control unit 120, and a storage unit 130. Note that the configuration of the display device 100C is not limited to the configuration shown in Figure 45, and other configurations are also possible as long as the desired processing can be achieved. Furthermore, in the following description, processing content that is common with the processing content of the first embodiment or the second embodiment described above will be omitted.

[0229] The data display unit 125 displays a lifestyle information input screen that reflects the input of lifestyle information based on user operations to the user operation reception unit 123. For example, when the data display unit 125 receives a tap operation on the button for inputting lifestyle information (gut health log) from the user operation reception unit 123 (login), it generates and displays an input screen that reflects only the first piece of lifestyle information confirmed during the previous input (see Figure 44).

[0230] Here, lifestyle information includes primary information, which is continuous, and secondary information, which is not continuous. For example, the lifestyle information entered by the user includes primary information, which includes lifestyle information that is continuous in daily life, such as meals, exercise, and sleep, and secondary information, which includes lifestyle information that is not continuous and occurs spontaneously in daily life, such as events like drinking parties or feeling unwell.

[0231] Here, the data display unit 125 is displayed, for example, as a screen reflecting the content from the previous input when the user logs into the screen for entering lifestyle information, but is not limited to this. For example, the data display unit 125 can also display a screen reflecting the content from the previous input when a button such as "Show previous input content" is entered (selected, pressed) on the lifestyle information input screen.

[0232] Furthermore, when a user logs into the screen for entering lifestyle information, the data display unit 125 displays a screen that reflects the latest lifestyle information stored in the lifestyle information storage unit 133, but is not limited to this. For example, the data display unit 125 can also display a screen that reflects the input content from the day before the date for which lifestyle information is to be entered. In addition, if the user has pre-set arbitrary lifestyle information in the lifestyle information storage unit 133, the data display unit 125 can also display a screen that reflects that default lifestyle information. Moreover, if a long period of time has passed since the user last entered lifestyle information when logging into the screen for entering lifestyle information, the data display unit 125 can display a screen that reflects the lifestyle information that has been entered most frequently, in addition to the latest lifestyle information.

[0233] Furthermore, the content of the first and second pieces of information mentioned above can be changed by the user. For example, if a user is continuously attending drinking parties, which are normally included in the second piece of information, the user can change this so that "drinking parties" are included in the first piece of information. In other words, the first and second pieces of information can be freely set by the user depending on whether or not they want to reflect the previous input. The first piece of information can be the content that the user wants to reflect the previous input on, and the second piece of information can be the content that the user does not want to reflect the previous input on.

[0234] The user operation reception unit 123 accepts changes to the input of lifestyle information based on user operations on the lifestyle information input screen, which reflects the latest input of lifestyle information. For example, on the lifestyle information input screen, which reflects the content of the previous input, the user operation reception unit 123 accepts a selection from the previously selected candidate to a different candidate by a tap operation from the user.

[0235] To explain with a specific example, the user operation reception unit 123 recognizes that the selection of lifestyle information candidates has changed from "yoga" to "running" when the user taps on a lifestyle information candidate indicating "running" on a lifestyle information input screen that reflects the selection of "yoga" as the latest lifestyle information stored.

[0236] Here, if the system accepts a change in the input content of the aforementioned lifestyle information, the data display unit 125 can, for example, move the display of the thick border indicating the selected state in accordance with the change in the selection candidate by user operation (see Figure 44). In addition, the data display unit 125 displays a dotted line when the selection is made by reflecting the previous input (see Figure 49), and displays a solid line when the user confirms the selection or when the system accepts a change in the input content by the user (see Figure 50), thereby allowing the user to understand whether the selection is made by reflecting the previous input or by user operation.

[0237] Furthermore, the user operation reception unit 123 can input the duration of the user's lifestyle information. For example, the user operation reception unit 123 accepts input of the duration of the lifestyle information related to the first information on the lifestyle information input screen.

[0238] Here, we will explain the process for receiving the duration of the user's lifestyle information. Figure 46 is a diagram showing an example of the process for inputting the start and end dates of lifestyle information according to the third embodiment. In Figure 46, an example is shown in which the duration of lifestyle information is received by inputting into the start and end buttons for the lifestyle information on the lifestyle information input screen.

[0239] As shown in Figure 46, the data display unit 125 displays a button indicating "Start" and a button indicating "End" for candidates of lifestyle information related to the primary information that has continuity, as well as a calendar to be used for input. The user operation reception unit 123 then accepts the start time from the user's "Start" button and date selection, and similarly accepts the end time from the user's "End" button and date selection. The user operation reception unit 123 then accepts the continuation period of the selected candidate from the acceptance of the start and end times.

[0240] Furthermore, the user operation reception unit 123 can, for example, accept only the start date when inputting the duration, if the selected lifestyle information candidate is still ongoing.

[0241] Furthermore, the data display unit 125 displays a lifestyle information input screen based on the duration. For example, regarding the lifestyle information input screen, the data display unit 125 displays a screen that generates only the lifestyle information candidates with relatively long durations that have been received, as lifestyle information candidates for selection by the user.

[0242] To illustrate with a specific example, the data display unit 125 is set to display up to three candidates for exercise-related lifestyle information. If the total number of days of continuous activity is highest for "yoga," followed by "running," and then "badminton," the lifestyle information candidates for "yoga," "running," and "badminton" can be displayed in order from left to right in the exercise-related lifestyle information input section of the lifestyle information input screen. In addition to the number of days of continuous activity, the data display unit 125 can also prioritize displaying lifestyle information candidates that are currently being continued, or display any lifestyle information candidate selected by the user.

[0243] (Example of information display on a display device) Next, we will describe examples of information displayed on the screen when each of the processing contents of the display device 100C described above is performed. Figures 47 to 51 show examples of lifestyle information displayed by the display device according to the third embodiment.

[0244] Figure 47 shows an example of the screen display of the lifestyle information input screen in the screen that shows the history information of the user's lifestyle (gut health log). As shown in Figure 47, the display device 100C displays a screen on the user's lifestyle information input screen that shows, from left to right, lifestyle information candidates for "Diet": "Yogurt," "Lactic acid bacteria beverage," "Seaweed," "Mushrooms," and "Fruit." The display device 100C also displays a screen that shows, from left to right, lifestyle information candidates for "Exercise": "Radio calisthenics," "Intestinal massage," "Yoga," and "Running." The display device 100C also displays a screen that shows, from left to right, lifestyle information candidates for "Lifestyle": "Early to bed, early to rise," "Stress," "Drinking parties," "Overeating and excessive drinking," and "Medication." The display device 100C also displays a screen that shows, from left to right, candidates for "Today's condition" (corresponding to the subjective information according to the first embodiment): "A," "B," "C," "D," and "E." The display device 100C also displays a screen showing a "Confirm" button.

[0245] Regarding the lifestyle information in Figure 47, it is assumed that "Diet" and "Exercise" are set as continuous primary information through user operation, while "Lifestyle Habits" are set as non-continuous secondary information.

[0246] Figure 48 shows an example of the screen display when past lifestyle information inputs are reflected in the lifestyle information input screen shown in Figure 47. As shown in Figure 48, when the display device 100C displays the lifestyle information input screen, it displays the screen that reflects the latest inputs of the first information by surrounding the previously entered information, "lactic acid bacteria beverage" and "yoga," with dotted lines. In addition, the display device 100C displays the previously entered subjective information "B" with a dotted line.

[0247] In FIG. 49, a screen display example when the selection of life information changes due to a user operation on the life information input screen shown in FIG. 48 is shown. As shown in FIG. 49, the display device 100C accepts a change of "lactic acid bacteria beverage" to "yogurt" for "meal" and selections of "stress" and "drinking party" for "lifestyle habits" with respect to the life information input screen shown in FIG. 47. Then, the display device 100C displays the candidates of life information of "yogurt", "stress", and "drinking party" received by the operation of the user so as to surround them with a solid line, thereby displaying the content changed or newly input by the current input by the user's operation.

[0248] In FIG. 50, a screen display example when the "confirm" button is input on the life information input screen shown in FIG. 49 is shown. As shown in FIG. 50, when the display device 100C accepts that the "confirm" button has been tapped on the life information input screen shown in FIG. 49, it determines that the input of the candidates of life information surrounded by a dotted line or a solid line in FIG. 49 has been confirmed, changes the dotted line to a solid line, and generates and displays a screen in which the "confirm" button is changed to the text "Logging completed".

[0249] The display device 100C can appropriately receive the life information input from the user and display the received content by sequentially displaying the screen display examples from FIG. 48 to FIG. 50 according to the operation of the user.

[0250] In FIG. 51, a screen display example in accepting the duration of life information is shown. As shown in FIG. 52, when inputting the duration for the life information of "lactic acid bacteria beverage", the display device 100C displays the "start" and "end" buttons connected by a solid line to the display of "lactic acid bacteria beverage".

[0251] (Example of processing flow) From here, the flow of various processes will be described based on the flowchart. FIG. 52 is a flowchart showing an example of the flow of processes performed by the display device according to the third embodiment. Note that each step in the flowchart shown in FIG. 52 can be executed in a different order, and there may be additional processes or omitted processes.
