By the way, at home, the burden of housework tends to be biased toward a specific person. Therefore, the particular person may be stressed to bear the burden of many household chores. For example, in Document 1, even if stress can be detected, the cause of the stress cannot be eliminated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a housework sharing system capable of improving comfort for users by appropriately sharing housework.

In order to solve the above problems, the housework sharing system of the first invention includes:
A housework sharing system in which a plurality of household chores to be shared by a plurality of users living in a house are determined in advance, and the sharing of the plurality of housework to each user is determined,
Housework burden detection means for detecting the burden situation of the housework for each of the users;
stress detection means for detecting a stress situation associated with the housework for each of the users;
How to share the household chores among the users based on the household chores burden status of each user detected by the housework burden detecting means and the stress status of each user detected by the stress detecting means. or a housework sharing determination means for determining the housework sharing;
a notification means for notifying each user of the division of housework determined by the division of housework determination means;
characterized by comprising

According to the first invention, the burden situation of housework and the stress situation associated with housework are determined for each user. Then, based on the determined housework burden situation and stress situation of each user, each user's share of housework is determined. From the user's housework burden situation and stress situation, it is possible to grasp how much housework burden the user feels stressed. In other words, it is possible to grasp the correlation between the user's housework burden and stress. Therefore, in the present invention, based on the correlation between housework and stress for each user, it is possible to determine, for example, how to share housework so that each user's stress is reduced. In addition, by being notified of the determined share of housework, each user can surely know his own housework behavior. As a result, housework can be divided appropriately, and comfort for the user can be improved.

The housework sharing system of the second invention is, in the first invention,
For each user, a biometric information acquiring means for acquiring biometric information when the user is doing the housework,
The stress detection means detects the stress situation of each user based on the biometric information of each user acquired by the biometric information acquisition means.

According to the second invention, biometric information is acquired while doing housework. For example, when the user is stressed by the housework behavior, it is conceivable that the user's biometric information changes during the housework behavior. According to the second invention, the stress situation in housework behavior is determined based on the biological information when the user is doing housework. This allows the user to clearly grasp the stress caused by the burden of housework.

The housework sharing system of the third invention is, in the second invention,
The biometric information acquiring means acquires a facial expression of the user as the biometric information of the user,
The stress detection means is characterized by detecting the stress situation of the user based on the obtained facial expression of the user.

For example, when the user is stressed by the housework behavior, the user's facial expression during the housework behavior becomes an expression that expresses an unpleasant feeling (for example, the corners of the mouth droop). According to the third invention, the stress situation in the housework behavior is determined based on the facial expression of the user. This makes it possible for the user to more clearly understand that the housework behavior is stressful for the user.

A housework sharing system of a fourth invention is, in any one of the first to third inventions,
The plurality of household chores include predetermined fixed household chores that are to be handled by a specific user, and a plurality of predetermined common household chores that can be handled by any of the users. cage,
The housework sharing determination means is characterized by having means for determining how each of the common housework should be shared among the users when the housework is shared.

Among domestic chores, there are fixed chores that only specific people can do due to time constraints. According to the fourth invention, each user's share of housework is determined by changing the person in charge of the common housework that any of the users can do, according to the stress situation of each user. Therefore, by changing the person in charge of common housework, the burden of fixed housework can be reduced, and the user's comfort can be enhanced.

An embodiment embodying the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a housework sharing system for determining housework sharing. In this embodiment, it is assumed that parents (father and mother) and their child (one) live as residents (hereinafter referred to as users) in the house 10 .

As shown in FIG. 1, a house 10 is provided with an entrance 11, a kitchen 12, a tatami area 13, a drying area 14, and a garbage station 15 as indoor spaces (areas). Cameras 21 to 25 are provided in the areas 11 to 15, respectively. The cameras 21 to 25 are installed, for example, on a wall or the like, and each camera 21 to 25 captures the motion of the user in the area and the user's face (particularly, the facial expression during the motion). Each of the cameras 21 to 25 is configured to start photographing by detecting a person, for example.

In addition to the areas 11 to 15, the house 10 is provided with a plurality of rooms, bathrooms, corridors, toilets, and other spaces, which are not shown.

Next, the electrical configuration of this system will be described.

The housework sharing system includes a controller 30 that supervises (controls) the system. The controller 30 is attached, for example, to the wall of a living room (not shown). The controller 30 comprises a well-known microcomputer comprising a CPU, ROM, RAM and the like. The controller 30 has a storage unit 31 that stores various information, and a timer 32 that has a timekeeping function, a timepiece function, and a calendar function.

In this system, a plurality of household chores to be shared by each user living in the house 10 is determined in advance. In this embodiment, the plurality of household chores are linked to each of the areas 11-15 as household chores to be performed in each of the areas 11-15. Specifically, the housework item in the entrance 11 is putting shoes on, the housework item in the kitchen 12 is cooking and washing dishes, the housework item in the tatami area 13 is folding the laundry, and the housework item in the clothesline area 14 is drying the laundry. is. Housework items at the garbage station 15 include preparation of combustible garbage or recyclable garbage (work to collect and put together from inside the house 10) and transporting the combustible garbage or recyclable garbage collected at the garbage station 15 to an outdoor garbage disposal site. Take out the garbage.

Here, the storage unit 31 is provided with a housework allocation storage area 31a for storing various information on housework allocation, and an information storage area 31b for storing each detection data. In the present embodiment, household items to be performed in each area 11 to 15 are assigned to each user. FIG. 2(a) shows an outline of the state of housework sharing stored in the housework sharing storage area 31a. As shown in FIG. 2(a), the household chores are classified into fixed household chores that are handled by a specific user and common household chores that are handled by any of the users. For example, cooking, which is breakfast preparation and dinner preparation, is regarded as a fixed household chore for the mother. In this embodiment, each user is assigned one or more fixed chores. As common household chores, for example, a plurality of household items, such as taking out the trash and putting shoes on, are defined, and each user is assigned at least one or more common household chores. Note that the housework sharing shown in FIG. 2A is for the current month (March in this embodiment).

The cameras 21 to 25 are connected to the controller 30, and the images (video) captured by the cameras 21 to 25 are sequentially input. The controller 30 performs image recognition processing on the images captured by the cameras 21 to 25, and each house item determined in each of the areas 11 to 15 is performed by a person (a person recognized as a person) in the image. determine whether or not the For example, the storage unit 31 stores each housework item determined in each of the areas 11 to 15 and the action to be performed in each of the areas 11 to 15 in association with each other. The controller 30 determines whether or not the motion of the person in each of the areas 11-15 recognized by the image recognition process matches the predetermined motion defined for each of the areas 11-15. If it is determined that they match, the controller 30 determines that the house item has been performed in each of the areas 11-15.

For example, it is assumed that the storage unit 31 stores in the storage unit 31 a pair of household chores at the entrance 11, such as putting shoes together, and an action of arranging the orientation of a plurality of shoes in one direction. In this case, when an action of arranging a plurality of shoes by a person in one direction is acquired (image recognition) by image recognition processing of an image photographed by the camera 21, the controller 30 determines that the shoes have been lined up.

If it is determined that each house item defined in each area 11-15 was performed by the person recognized in the image, the controller 30 identifies the user who performed the house item. Here, the user's face is registered in advance as image information in the storage unit 31, and the controller 30 can identify the father, mother, or child based on the image information. Therefore, after it is determined that each house item specified in each of the areas 11 to 15 has been performed, the user who performed the house item is specified. As a result, the performed housework item and the user who performed the housework item are linked, and the controller 30 detects (acquires) the housework burden information related to the housework burdened by each user. there is Note that the controller 30 corresponds to the housework burden detecting means.

The controller 30 also calculates (detects) the stress level of the household item based on the facial expression of the user performing the household item. Specifically, the controller 30 performs image recognition processing on the images captured by the cameras 21 to 25, classifies the facial expressions of people performing household items, and calculates stress levels. In this embodiment, stress levels are defined as follows for each classification (five classifications) of human facial expressions;
・Stress level 1 (relatively low stress): Doing housework while laughing (detected by image recognition, such as laughing with the mouth open)
・Stress level 2 (low stress): Doing household chores with a smile (detected by image recognition, such as when the corners of the mouth are raised)
・ Stress level 3 (intermediate stress): Concentrating on housework (expressionlessness detected by image recognition)
・ Stress level 4 (high stress): Doing housework dissatisfied (detected by image recognition, such as the corners of the mouth drooping)
・Stress level 5 (high stress): Housework is done while angry (upper lip raised, mouth pressed, both eyebrows lowered toward the center, etc. detected by image recognition).

Therefore, after it is determined that each house item specified in each of the areas 11 to 15 has been performed and the user who has performed the house item is specified, the user's stress when performing the house item using this criterion Level is determined. As a result, the housework item and the stress situation of the user who performed the housework item are linked, and the controller 30 detects (acquires) the stress information (stress level) associated with each user's housework. there is Note that the controller 30 corresponds to stress detection means and biological information acquisition means.

When the controller 30 acquires each user's housework burden information and each user's stress information associated with housework, the controller 30 stores each of these pieces of information in the information storage area 31b in association with the acquisition time at which the information was acquired. Thus, each user's housework burden information and stress information are stored in the information storage area 31b each time. Here, FIG. 2B shows an example of the housework burden information and stress information stored in the information storage area 31b. As shown in FIG. 2(b), the household item determined to be performed by each user is stored as housework burden information, and the stress level calculated as the stress when performing the household item is stored as stress information. It is

A display unit 33 is connected to the controller 30 . The display unit 33 is attached, for example, to the wall of a living room (not shown). The display unit 33 is capable of displaying information about the division of housework, and the display is controlled by the controller 30 . The display unit 33 corresponds to notification means.

Next, the housework burden determination process executed by the controller 30 will be described based on the flowchart shown in FIG. Based on the clock function (current time) of the timer 32, the housework burden determination process is triggered when the determination time comes. That is, this process is performed every day. In the present embodiment, the determination time is set at nighttime, for example, 3:00.

In FIG. 3, in step S11, each housework burden information of each user on the current day (today) is read from the information storage area 31b and acquired. In the subsequent step S12, the stress information of each user on the day is read from the information storage area 31b and acquired. In steps S11 and S12, all of the housework burden information and stress information of each user stored each time they are acquired on the day are read out and acquired.

In step S13, based on the housework burden information and stress information of each user acquired in steps S11 and S12, the number of housework burdens and stress level for the current day are calculated for each user. Here, the number of housework burdens is the total value of household items that each user did on the day, and the stress level is the average stress level of each user on the day. The stress degree is a value obtained by dividing the total value of stress levels calculated on the day by the number of housework burdens of the user. Note that FIG. 2B shows an example of the number of housework burdens and stress levels on the day. As shown in FIG. 2(b), for each of the father, mother, and child, the number of housework items performed on the day (i.e., the number of housework burdens) is calculated, and the average stress level when performing the housework items (i.e., degree of stress) is calculated.

In step S14, the number of household chores and the degree of stress calculated in step S13 are stored in the information storage area 31b. As a result, the daily number of household chores and the degree of stress are stored in the information storage area 31b. After that, this process is terminated.

Next, the housework assignment determination process executed by the controller 30 will be described based on the flowchart shown in FIG. Based on the clock function and the calendar function of the timer 32, the household chore assignment determination process is triggered by the determination time at the end of the month. That is, this process is performed once a month. The judgment time is set at nighttime, for example, 3:30.

In FIG. 4, in step S21, a monthly average of the number of housework burdens is calculated based on the history of the number of housework burdens stored in the information storage area 31b. In the following step S22, a monthly average of stress levels is calculated based on the history of stress levels stored in the information storage area 31b. Here, FIG. 5 shows an example of a monthly average of the number of housework burdens and a monthly average of stress levels calculated for each of the father, mother, and child.

Subsequently, in step S23, it is determined whether or not there is a user with high stress based on the one-month average stress level calculated in step S22. Here, in the present embodiment, a stress reference value is determined in advance, and it is determined that the stress is high when the one-month average stress level is higher than the stress reference value. In this embodiment, the stress reference value is set to 4, for example. If there is a user with a stress reference value of 4 or more, that is, if there is a user with high stress, the process proceeds to step S24. If there is no user with a stress reference value of 4 or more, that is, if there is no user with high stress, the process proceeds to step S26.

In step S24, a user in charge of fixed housework is determined (corresponding to housework sharing determination means). Here, when determining the user in charge of the share of housework, the share of housework for the current month (March) stored in the housework share storage area 31a is referred to. That is, in this step, the user in charge of fixed housework is determined based on the housework assignment for the current month (every March). Note that fixed housework is predetermined, but can be changed by operating an operation unit (not shown) of the controller 30 . If the user in charge of fixed housework has been changed, the change is reflected in this step, for example. In this embodiment, since the user in charge of the fixed housework is not changed in the housework sharing determination process, the user in charge of the fixed housework is assumed to be the same as the fixed user in charge of the housework for the current month (March).

In subsequent step S25, a user in charge of common housework is determined (corresponding to housework sharing determination means). That is, in this step, the user in charge of common housework is determined based on the housework assignment for the current month (every March). In this embodiment, a user in charge of common housework is determined by performing a process of assigning at least one common housework of a user with high stress as a housework in charge of another user. As a result, it is possible to reduce the burden of housework of the user who is stressed by the burden of housework, thereby reducing the user's stress. In the present embodiment, the common housework of a user with high stress is assigned to a user with a low monthly average number of household chores, excluding users with high stress.

Here, the process of determining the user in charge of common household chores will be described using an example of FIGS. For example, in the case of FIG. 5, the father has a monthly average stress level of 4 or more, and thus is determined as a high-stress user. In this case, in order to reduce the father's housework burden, in the current month's (March) housework assignment, the household items that are the common household chores that the father is in charge of are removed from the father's chores, and the other users ( In this case, it is assigned as the housework in charge of the mother or child. In the examples of FIGS. 2A and 5, since the child has a smaller monthly average number of housework burdens than the mother and child, the child becomes the new user in charge of the common household chores that the father is in charge of. In this case, for example, taking out the trash, which was a common household chore that the father was in charge of, is decided to be in charge of the child. After the common housework of the user with high stress is assigned to other users as described above, the process proceeds to step S26.

When it is determined in step S23 that there is no user with high stress and when the user in charge of common housework is determined in step S25, the process proceeds to step S26. (equivalent to proposal means). For example, in the case of the examples of FIGS. 2A and 5, as shown in FIG. 6, the display unit 33 displays "Your father seems to be under a lot of stress. The division of housework has been changed." At the same time, the next month's housework assignment table (each user's housework assignment) is displayed. In this case, the garbage disposal for which the user in charge has been changed from the current month in the next month is highlighted. If it is determined in step S23 that there is no user with high stress, the division of housework for the current month has not been changed. It is displayed as a housework sharing table.

In the subsequent step S27, the determined share of housework is stored in the share of housework storage area 31a. That is, the next month's (April in this embodiment) housework assignment is stored as the current month's (here, April's) housework assignment (that is, the current month's housework assignment is updated). At this time, as shown in FIG. 2A, each household item is classified into fixed household chores and common household chores, and stored for each user's responsibility. After the storage process, this process ends.

According to the configuration of the present embodiment described in detail above, the following excellent effects are obtained.

According to the present embodiment, the number of housework burdens and the degree of stress associated with housework (average stress level during housework) are determined for each user on a daily basis. At the end of the month, each user's share of housework for the next month is determined based on the determined number of household chores and stress level for each user. By acquiring the number of household chores and the degree of stress of the user every day, it is possible to grasp how much housework the user feels stressed by. In other words, it is possible to grasp the correlation between the user's number of housework burdens and stress. For example, even if the number of household chores to be borne is minimal, the person may be busy with work or the like and feel stressed by the burden of housework. In this embodiment, based on the correlation between the number of household chores and the stress level for each user, the division of housework is determined at the end of the month so that each user's stress is reduced. As a result, it is possible to optimize the division of housework so as to minimize the burden of housework, which is a cause of stress. Therefore, household chores can be divided appropriately, and comfort for the user can be improved.

For example, when the user is stressed by the household item, the user's facial expression when performing the household item becomes an expression that expresses an unpleasant feeling (for example, the corners of the mouth droop). According to the present embodiment, the user's facial expression while doing housework is acquired, and the stress level of the household chore item is determined based on the acquired facial expression of the user. This makes it possible for the user to clearly understand that housework is stressful.

According to the present embodiment, fixed housework to be performed by a specific user and common housework to be performed by any of the users are defined. Among household chores, there are some chores that only specific people can do due to time constraints, and the burden of such chores can be heavy. According to this embodiment, each user's share of housework is determined by changing the person in charge of common housework according to the stress level of each user. Therefore, by changing the person in charge of common housework, the burden of fixed housework can be reduced.

According to this embodiment, each user can surely know each other's share of housework by being notified of the determined share of housework. As a result, each user can grasp the user who is stressed by the burden of housework, and each user can understand and bear the burden of the shared housework.

The present invention is not limited to the above embodiments, and may be implemented as follows, for example.

(1) In the above-described embodiment, facial expressions while performing household items are acquired as biometric information, but the biometric information may be pulse, voice, body temperature, amount of perspiration, and the like. For example, biometric information can be obtained by providing biosensors (body motion sensors, temperature sensors, etc.) in each of the areas 11 to 15, or by wearing a wearable biosensor on the body of each user.

(2) In the above embodiment, housework burden information and stress information are acquired based on images captured by the cameras 21 to 25 provided in each of the areas 11 to 15. The information may be acquired by means other than the cameras 21-25. Also, the information on the burden of housework and the information on stress may not be obtained from the same means, but may be obtained from different means.

For example, the equipment used for a particular household item may be in place. In this case, the controller 30 can acquire household chore burden information by providing device operation detection means for detecting the operation status of the device and user position detection means for detecting the position of the user. For example, if an appliance is detected to be operating and a user is detected to be at a given location on the appliance, the controller 30 will indicate that the user is performing that particular household item. Judge. That is, the controller 30 can acquire information on the burden of housework based on the results detected by the device operation detection means and the user position detection means. For example, if the appliance is a stove, it can be determined that cooking is being done as a household item, and if the touch sensor type water faucet provided in the kitchen 12 is being used, it can be determined that dishes are being washed (tidying up).

(3) In the above embodiment, when the common housework of a user with high stress is assigned to other users, the common housework is assigned to the user with a small number of housework burdens. Not restricted. For example, common housework of a user with high stress may be assigned to a user with low stress. Alternatively, household items that are likely to cause stress may differ depending on the user. In the above embodiment, since the stress information is acquired based on the user's facial expression while doing housework, it is possible to compare the user's stress level for each common housework item. Therefore, for example, each user may be assigned a house item that is less stressful. In this case, it is possible to optimize the sharing of housework, and to further improve the user's comfort.
