The control unit 330 manages the usage state of the tableware 10 based on the usage information acquired from the electronic device 100. The usage state of the tableware 10 is, for example, information on whether or not the tableware 10 is being used (in use) for providing food and drink, and information on the table on which the tableware 10 is used (for example,). The table number for identifying the table, the position of the table, etc.) may be included.

The management device 300 can identify, for example, a customer who has been staying in the store for a long time by estimating the store usage status of the user by the control unit 330. The store usage status may include, for example, information about a table or seat in the store used by the customer. The details of the management of the usage state of the tableware 10 and the estimation processing of the store usage state by the control unit 330 will be described later.

The input unit 340 receives an operation input from a user who uses the management device, and is composed of, for example, an operation button (operation key). The input unit 340 may be configured by a touch panel, and an operation key for receiving an operation input from the user may be displayed on a part of the display device to accept the touch operation input by the user.

The notification unit 350 notifies information by sound, vibration, an image, or the like. The notification unit 350 may include a speaker, an oscillator, and a display device. The display device can be, for example, a liquid crystal display (LCD), an organic EL display (OELD: Organic Electro-Luminescence Display), an inorganic EL display (IELD: Inorganic Electro-Luminescence Display), or the like. The notification unit 350 can notify, for example, the usage status of the tableware 10 and the store usage status of the customer.

Next, an example of the management procedure by the management system 1 will be described with reference to FIG.

The electronic device 100 transmits a wireless power transmission request from the communication unit 120 (step S101). The electronic device 100 may transmit a power transmission request, for example, when the timing start condition described later is satisfied.

Upon receiving the power transmission request from the electronic device 100, the power transmission device 200 transmits wireless power to the electronic device 100 that has transmitted the power transmission request in response to the power transmission request (step S102).

The transmission of the power transmission request in step S101 may be executed at an appropriate timing. For example, the electronic device 100 may transmit a power transmission request periodically or irregularly. For example, the electronic device 100 may transmit a power transmission request when the amount of electricity stored in the electricity storage unit 150 becomes equal to or less than a predetermined threshold value.

The electronic device 100 does not have to transmit the power transmission request. In this case, the power transmission device 200 may transmit wireless power regardless of the power transmission request from the electronic device 100.

The electronic device 100 starts timekeeping when the condition for starting timekeeping (hereinafter, also referred to as “timekeeping start condition”) is satisfied (step S103).

Timekeeping is done to measure the time the tableware 10 has been used. Therefore, the timing start condition can be a condition that can determine that the tableware 10 has started to be used.

For example, the timing start condition may be satisfied by an employee of a restaurant or the like performing a predetermined operation. For example, when a user places an order at a restaurant or the like and an employee provides food and drink to the user, the employee can communicate with an electronic device 100 used as a container for food and drink provided to the user. A predetermined operation may be performed in the device. When the terminal device notifies the electronic device 100 that the predetermined operation has been performed, the electronic device 100 can determine that the time counting start condition is satisfied and start the time counting.

For example, the timekeeping start condition may determine whether or not the electronic device 100 provided in the tableware 10 is satisfied based on a predetermined change that occurs in the tableware 10. For example, assume that the tableware 10 is a coffee cup. When a customer orders coffee, the temperature of the tableware 10 changes when coffee is poured into the tableware 10 (for example, when hot coffee is poured into the tableware 10, the temperature of the tableware 10 rises). When the temperature detected by the temperature sensor 160A changes, the control unit 140 of the electronic device 100 may determine that the tableware 10 has started to be used and that the timing start condition has been satisfied. That is, when the temperature sensor 160A detects a change in temperature equal to or higher than a predetermined value, the electronic device 100 can determine that the timing start condition is satisfied and start timing. The electronic device 100 may determine that the timing start condition is satisfied when the temperature detected by the temperature sensor 160A is equal to or higher than a predetermined threshold value or lower than the threshold value.

The timing disclosure condition is not limited to these examples, and may be any condition that can determine that the tableware 10 has started to be used.

After starting the timekeeping, the electronic device 100 generates usage information of the tableware 10. The electronic device 100 may continuously generate usage information. The electronic device 100 may generate usage information on a regular or irregular basis. The electronic device 100 may generate usage information when a predetermined condition is satisfied. The predetermined condition may be, for example, a case where the predetermined information described below exceeds a predetermined threshold value. In FIG. 3, steps S104 to S110 are described as an example of the usage information generation process. The electronic device 100 can repeatedly execute steps S104 to S110, for example. Details of steps S104 to S110 will be described.

In the usage information generation process, the electronic device 100 acquires the usage time of the tableware 10 that has started timing (step S104). The electronic device 100 can acquire the usage time by measuring the elapsed time after the start of time counting in the control unit 140.

The electronic device 100 determines whether or not the time condition is satisfied based on the usage time of the tableware 10 acquired in step S104 (step S105). The time condition may be stored in the storage unit 130 in advance, for example. The condition regarding time may be, for example, the maximum staying time of the customer at the store, which is desired by the operator of the restaurant or the like. The condition regarding time may be, for example, the maximum staying time that the operator of a restaurant or the like permits the guest to stay.

The time conditions may be determined by various methods. For example, as for the condition regarding time, a predetermined threshold value may be set in advance for each store. The predetermined threshold value may be a different value depending on, for example, a time zone. For example, the predetermined threshold value may be set so that the value between 12:00 and 14:00 and between 18:00 and 20:00 is shorter than the value in other time zones. From 12:00 to 14:00 and from 18:00 to 20:00, the number of customers at restaurants tends to increase compared to other time zones, so the store should prevent long-term stays of customers. You may wish. By setting a predetermined threshold value to a different value according to the time zone, the maximum staying time of the customer desired by the store can be set for each time zone.

For example, as for the condition regarding time, a threshold value may be set according to the amount of goods ordered by the user (hereinafter, also referred to as “order amount”). The threshold value may be set to a higher value as the order amount is higher, for example. In this case, the maximum staying time of the customer desired by the operator of the restaurant or the like becomes longer in proportion to the order amount. The threshold value may be set stepwise according to, for example, the order amount. In this case, the maximum staying time of the customer desired by the operator of the restaurant or the like has a predetermined correlation with the order amount. When the threshold as a condition regarding time is set according to the order amount of the user, for example, the register provides the user with information on the amount of money that the employee enters into the register when the customer places an order. The electronic device 100 included in the tableware 10 for food and drink is notified. That is, the register is configured to be able to communicate with the electronic device 100, and transmits information regarding the order amount of the user to the electronic device 100. When the electronic device 100 acquires the information regarding the order amount of the user, the electronic device 100 sets a threshold value according to the order amount as a condition regarding the time by referring to, for example, a table or a calculation formula stored in the storage unit 130 in advance. The input of the order by the employee may be performed by using, for example, a portable data terminal (PDT), which is a terminal device that can accept the operation input of the order and is portable.

The time condition is not limited to these examples, and may be set as an arbitrary condition regarding the time the customer stays at the store. For example, when the usage time of the tableware 10 exceeds the threshold value set as the time-related condition, the electronic device 100 may determine that the threshold value condition is satisfied.

In the process of generating usage information, the electronic device 100 acquires the temperature of the tableware 10 (step S106). The electronic device 100 can handle the temperature measured by the temperature sensor 160A as the temperature of the tableware 10.

Based on the temperature acquired in step S106, the electronic device 100 determines whether or not the temperature-related condition is satisfied (step S107). The temperature-related conditions may be stored in the storage unit 130 in advance, for example. The temperature condition is set, for example, as a temperature threshold. The temperature-related condition may be, for example, a condition in which the electronic device 100 can estimate the state of the food or drink provided by the restaurant or the like to the user. The state of the food and drink may include, for example, whether or not the user has consumed the food and drink, a preferable serving temperature of the food and drink, and the like.

For example, suppose that a customer orders hot coffee as food and drink, and an electronic device 100 is provided at the bottom of a coffee cup for serving hot coffee. It is assumed that the threshold value as a condition regarding the temperature is set to a temperature higher than room temperature and lower than the temperature that the bottom of the coffee cup can take when hot coffee is contained in the coffee cup. When hot coffee is contained in the coffee cup, the temperature detected by the temperature sensor 160A becomes a value higher than the threshold value. On the other hand, when the customer finishes drinking coffee and there is no coffee in the coffee cup, the temperature detected by the temperature sensor 160A becomes a value lower than the threshold value (close to normal temperature). The electronic device 100 may determine that the condition relating to the threshold value is satisfied when, for example, the temperature detected by the temperature sensor 160A falls below a predetermined threshold value. Thereby, the electronic device 100 can estimate whether or not the user has consumed the food or drink based on whether or not the condition regarding the temperature is satisfied.

For example, suppose that a customer orders hot coffee as food and drink, and an electronic device 100 is provided at the bottom of a coffee cup for serving hot coffee. It is assumed that the threshold value as a condition regarding temperature is set to the lowest temperature in the temperature range preferably provided as hot coffee, for example. The minimum temperature may be set by, for example, a restaurant or the like. When the coffee is in the coffee cup, the temperature detected by the temperature sensor 160A is determined according to the temperature of the coffee in the coffee cup. That is, the temperature detected by the temperature sensor 160A has a predetermined correlation with the temperature of the coffee in the coffee cup. Therefore, when the temperature of coffee falls below a predetermined temperature, it falls below the threshold value which is the minimum temperature. For example, when the temperature detected by the temperature sensor 160A falls below the threshold value, the electronic device 100 may determine that the condition relating to the threshold value is satisfied. In this case, in the example here, it means that the temperature of the hot coffee is lower than the preferable temperature set by the restaurant or the like.

The temperature condition is not limited to these examples, and may be set as an arbitrary condition regarding the temperature of the tableware 10. For example, when the usage time of the tableware 10 exceeds or falls below the threshold value set as the time-related condition, the electronic device 100 may determine that the threshold value condition is satisfied.

In the usage information generation process, the electronic device 100 acquires the motion of the tableware 10 (step S108). The electronic device 100 can handle the motion measured by the motion sensor 160B as the motion of the tableware 10.

Based on the motion acquired in step S108, the electronic device 100 determines whether or not the condition related to the motion is satisfied (step S109). Conditions related to motion may be stored in the storage unit 130 in advance, for example. The condition relating to the motion may be, for example, a condition capable of determining that the tableware 10 has performed a specific motion.

For example, the condition regarding motion may be determined by the inclination of the tableware 10 with respect to the vertical direction. For example, when the tableware 10 is a container for beverages such as a coffee cup, the condition regarding motion may be set as an inclination indicating that the tableware 10 has fallen. For example, suppose a customer orders hot coffee as food and drink. When the tableware 10 (coffee cup) containing hot coffee falls, the coffee in the coffee cup spills from the tableware 10. When the motion-related condition is set as an inclination indicating that the tableware 10 has fallen, the electronic device 100 can presume that the beverage in the tableware 10 may have spilled when the motion-related condition is satisfied. The electronic device 100 may determine that the condition regarding motion is satisfied when, for example, the inclination of the tableware 10 exceeds the inclination indicating that the tableware has fallen.

The condition related to the motion is not limited to this example, and may be set as an arbitrary condition related to the motion of the tableware 10. In addition to the above-mentioned inclination, the condition related to the motion may be set as a condition related to the movement of the tableware 10, for example.

The electronic device 100 generates usage information of the tableware 10 based on the usage time, temperature and motion acquired in steps S104, S106 and S108, respectively, and the result of the determination in steps S105, S107 and S109 (step S110). The usage information of the tableware 10 includes the usage time, temperature and motion acquired in steps S104, S106 and S108, respectively, and information on the determination result in steps S105, S107 and S109. The electronic device 100 may generate usage information, for example, when it is determined that the condition is satisfied in at least one of steps S105, S107 and S109.

The electronic device 100 transmits the usage information generated in step S110 to the management device 300 (step S111).

The management device 300 manages the usage state of the tableware 10 based on the usage information received from the electronic device 100 (step S112).

The management device 300 estimates the store usage status by the user based on the usage information received from the electronic device 100, and manages the estimated store usage status (step S113).

The management device 300 can manage the usage status of the tableware 10 and the store usage status of the customer by using, for example, the management table shown in FIG. In the management table, the usage status of the tableware 10 and the store usage status of the customer are input.

In the example of the management table shown in FIG. 4, the management device 300 has eight items such as an electronic device ID, a table number, the number of people, an ordered item, a temperature, an amount of money, a stay permit time, a stay time, and a motion, and the usage state of the tableware 10. And manages the store usage status of customers.

The electronic device ID is information that uniquely identifies the electronic device 100 used as a container for food and drink provided to the user. The electronic device ID may be composed of, for example, numbers or letters, or a combination thereof. The electronic device 100 may transmit its own electronic device ID to the management device 300 as usage information.

The table number is a number that identifies the table used by the customer. The table number may be determined in association with the position where the table is arranged in advance in each store, for example. For example, when an employee receives an order from a customer, the table number can be entered by using a register or a PDT in association with the order contents. The entered table number is transmitted to the electronic device 100 included in the tableware 10 for food and drink provided to the user, and is stored in, for example, the storage unit 130. The electronic device 100 may transmit the table number stored in the storage unit 130 to the management device 300 as usage information in association with its own electronic device ID.

The number of people is the number of customers who use one table. For example, when an employee receives an order from a customer, the number of people can be input by using a register or a PDT in association with the order contents.

The residence permit time is the maximum stay time that the operator of the restaurant or the like permits the guest to stay. The permitted stay time may be, for example, the same as the maximum stay time described as the above-mentioned time condition. The residence permit time may be set in advance for each store, for example, or may be set according to the order amount. The residence permit time may be stored in the storage unit 130 of the electronic device 100, for example. The residence permit time may be determined by the electronic device 100 or the management device 300 when determined according to the order amount.

The staying time is the time when the customer is staying at the store. The management device 300 can determine, for example, the usage time of the tableware 10 received as usage information from the electronic device 100 as the staying time of the user.

The motion is the motion of the tableware 10. The management device 300 can handle, for example, the determination result of whether or not the condition related to motion is satisfied, which is received as usage information from the electronic device 100, as the motion of the tableware 10.

With reference to the management table shown in FIG. 4, the table with table number 1 is used by one customer. This customer ordered hot coffee. The residence permit time of this user is 30 minutes, but the stay time at the time when the management table is created is 65 minutes.

The table with table number 4 is used by one customer. This customer ordered hot coffee. The residence permit time of this user is 30 minutes, and the stay time at the time when the management table is created is 10 minutes. The coffee cup containing the coffee provided to this customer is in a fallen state.

Referring to FIG. 3 again, the management device 300 notifies the usage state of the tableware 10 and the store usage status of the customer from the notification unit 350 (step S114). When the notification unit 350 includes a display device, the management device 300 notifies the display device by displaying the usage status of the tableware 10 and the store usage status. The notification unit 350 may notify by displaying at least a part of the information in the management table shown in FIG. 4, for example. The notification unit 350 may notify information about the table number, the number of people, the permitted stay time, the stay time, and the motion, for example.

For example, the management device 300 may notify specific information separately from other information. The notification that is distinguished from other information may be, for example, changing the character color, font, or character thickness in the information displayed on the display device. The notification that is distinguished from other information may be, for example, to output voice in addition to the display on the display device. The management device 300 is not limited to these examples, and the information may be distinguished and notified by any other method.

The specific information that the management device 300 notifies differently from other information may be, for example, information related to the content that the electronic device 100 determines in steps S105, S107, and S109 that the conditions are satisfied. For example, when it is determined that the time-related condition is satisfied when the staying time of the user exceeds the permitted staying time, the management device 300 provides information on the electronic device 100 corresponding to the user who stays beyond the permitted staying time. , May be determined as specific information. For example, when it is determined that the temperature condition is satisfied when the temperature of the tableware 10 becomes lower than the predetermined temperature, the management device 300 relates to the electronic device 100 in which the temperature measured by the temperature sensor 160A is lower than the predetermined temperature. The information may be determined as specific information. For example, when it is determined that the condition related to motion is satisfied when the tableware 10 falls, the management device 300 determines as specific information information about the electronic device 100 provided in the tableware 10 whose inclination is equal to or greater than a predetermined inclination. You can do it.

The store employee can know the usage status of the tableware 10 and the store usage status of the customer from the information notified by the notification unit 350. Store employees can easily recognize the specific information by being notified of the specific information separately from other information.

With reference to the management table shown in FIG. 4 again, the user of the table of table number 1 has a stay permission time of 30 minutes, whereas the actual stay time is 65 minutes. The management device 300 determines the staying time of the user of the table of the table number 1 as specific information, and can display the display of "65 minutes" in red or the like on the display device, for example. The employee can recognize that the user of the table of table number 1 is staying for a long time by the display on the management device 300. In this case, the employee can, for example, urge the customer of the table of table number 1 to make an additional order. When the customer places an additional order, the permitted stay time can be changed, for example, according to the additional order amount.

The employee can recognize that there is no user in the table of table number 2 based on the display of the display device of the management device 300. However, for example, suppose an employee visually discovers that a person is using the table with table number 2. In this case, the employee can recognize that this person is using the table of table number 2 without placing an order. In this case, the employee may be careful to refrain from using the table or ask the person to place an order. This method can be used, for example, when the restaurant or the like is a food court.

For example, it is assumed that the threshold value as a condition regarding the temperature of hot coffee is set to 30 ° C. In the table of table No. 3, since the temperature of the hot coffee is 20 ° C., the temperature of the hot coffee is lower than the threshold value of 30 ° C. and satisfies the temperature condition. In this case, the management device 300 determines the temperature of the hot coffee in the table of the table number 3 as specific information, and can display the display of "20 ° C." in red or the like on the display device, for example. The employee can determine from the display on the management device 300 that the hot coffee in the table of table number 3 has finished drinking or the temperature of the hot coffee is lower than the preferable temperature. In this case, the employee can, for example, urge the customer of the table of table number 3 to make an additional order (for example, refill) or propose a product exchange.

In the example shown in FIG. 4, the management device 300 determines from the electronic device 100, for example, that the condition related to motion is satisfied in the tableware 10 (coffee cup) of the user of the table of the table number 4, that is, the coffee cup falls. The information that the coffee is used is acquired as usage information. In this case, the motion that the tableware 10 has fallen can be determined as specific information. In this case, the management device 300 can display the display of "cup fall" in red or the like on the display device, for example. The employee can recognize that the cup has fallen in the table of table number 4 by the display on the management device 300. At this time, the employee can go to the table of table number 4 to put away the fallen cup.

Regarding the example of the table of table number 4, the management device 300 may notify a predetermined alert based on, for example, a state determined by combining temperature and motion. For example, the management device 300 may notify a predetermined alert when the cup is in a state of being overturned and the temperature is equal to or higher than a predetermined temperature (for example, 50 ° C. or higher). In this case, it is estimated that coffee above a predetermined temperature has spilled in the table of table number 4, so when the employee recognizes the alert, he / she should immediately check whether the customer is burned. Can be done. The alert can be done in any way that the employee can recognize, for example by voice output.

As described above, according to the management system 1 according to the first embodiment, wireless power is transmitted to the electronic device 100 provided in the tableware 10, and the electronic device 100 uses the received wireless power to use the tableware 10. Information can be sent. That is, in the electronic device 100, the terminal for receiving the power supply is not exposed from the electronic device 100. Therefore, the tableware 10 provided with the electronic device 100 may come into contact with water by being used for providing food and drink or being washed, but the tableware 10 provided with the electronic device 100 is brought into contact with water. be able to. That is, according to the electronic device 100, the water resistance is improved. As a result, the user of the management system 1 can handle the tableware 10 naturally without paying special attention, so that the usefulness can be improved according to the management system 1.

Further, since the management system 1 is a system that manages the usage state of the tableware 10 in a restaurant or the like and the store usage status of the user, the electronic device 100 needs to be always driveable. Since the electronic device 100 according to the present embodiment receives and drives wireless power, it can be driven by receiving power supply even while the tableware 10 including the electronic device 100 is provided to the user.

In the above embodiment, in the description of the conditions relating to temperature, the description has been made using the example of hot coffee. However, the temperature condition does not have to be related to the temperature of food and drink served at a temperature higher than room temperature as in hot coffee. The temperature-related conditions may be related to the temperature of food and drink provided at a temperature lower than room temperature, such as iced coffee.

For example, it is assumed that the threshold value as a condition regarding temperature is set to a temperature lower than room temperature and higher than the temperature that the bottom of the coffee cup can take when iced coffee is contained in the glass. When the glass contains iced coffee, the temperature detected by the temperature sensor 160A is lower than the threshold value. On the other hand, when the customer finishes drinking coffee and there is no coffee in the coffee cup, the temperature detected by the temperature sensor 160A becomes a value higher than the threshold value (close to normal temperature). The electronic device 100 may determine that the condition relating to the threshold value is satisfied when, for example, the temperature detected by the temperature sensor 160A exceeds a predetermined threshold value.

In order to determine whether or not food or drink remains in the tableware 10 both when the food and drink is higher than room temperature and when the temperature is lower than room temperature, for example, the threshold value as a condition regarding temperature is set based on, for example, room temperature. It may be set to a value within a predetermined range. The threshold value as a condition regarding temperature may be set to, for example, a value of room temperature ± 10 ° C.

In the above embodiment, the power transmission device 200 and the management device 300 have been described as independent devices, but the power transmission device 200 and the management device 300 do not necessarily have to be independent devices. For example, the management system 1 may include a power transmission management device having the functions of the power transmission device 200 and the management device 300 described above. In this case, the power transmission management device may transmit wireless power to the electronic device 100 and manage the usage state of the tableware 10 and the store usage status of the customer based on the usage information received from the electronic device 100.

When the management system 1 includes a power transmission management device in place of the power transmission device 200 and the management device 300, the power transmission management device has a function of specifying the position of each electronic device 100, that is, the table on which the electronic device 100 is arranged. You may be doing it. For example, the power transmission management device receives a power transmission request from each electronic device 100. The power transmission management device can estimate the distance from the power transmission management device to the electronic device 100 based on the signal strength of the power transmission request. The power transmission device 200 can estimate the direction of the electronic device 100 with respect to the power transmission management device based on the direction in which the power transmission request is transmitted. The power transmission management device can identify the table on which the electronic device 100 is arranged based on the estimated distance and direction.

In the above embodiment, it has been described that the electronic device 100 transmits a power transmission request to the power transmission device 200, but the electronic device 100 may transmit a rapid power transmission request different from the normal power transmission request. The electronic device 100 may transmit a rapid power transmission request, for example, when the electric power stored in the power storage unit 150 becomes equal to or less than a predetermined power storage amount. Upon receiving the rapid power transmission request, the power transmission device 200 may preferentially transmit wireless power to the electronic device 100 that has transmitted the rapid power transmission request. Priority transmission of wireless power may include, for example, transmitting wireless power at a higher output than normal wireless power transmission.

In the above embodiment, the electronic device 100 may further include a temperature adjusting unit. FIG. 5 is a functional block diagram showing a schematic configuration of a modification of the electronic device 100. The temperature adjusting unit 170 has a heating and / or cooling function. The temperature adjusting unit 170 may include, for example, a heating wire and / or a Peltier element. When the temperature adjusting unit 170 has a heating function, the temperature adjusting unit 170 can heat the tableware 10 provided with the electronic device 100. As a result, when the food or drink provided by the tableware 10 is higher than room temperature, the temperature of the food or drink can be easily maintained. When the temperature adjusting unit 170 has a cooling function, the temperature adjusting unit 170 can cool the tableware 10 provided with the electronic device 100. As a result, when the food or drink provided by the tableware 10 is lower than the room temperature, the temperature of the food or drink can be easily maintained.

The temperature adjustment (that is, heating or cooling) by the temperature adjusting unit 170 is controlled by the control unit 140. The control unit 140 can determine whether or not the condition relating to the predetermined temperature is satisfied based on the temperature acquired by the temperature sensor 160A, and can control the temperature adjustment by the temperature adjusting unit 170 based on the determination result. For example, when the temperature acquired by the temperature sensor 160A is higher than the room temperature, the control unit 140 may be heated by the temperature adjusting unit 170 so that the temperature of the food and drink is less likely to decrease. For example, when the temperature acquired by the temperature sensor 160A is lower than the room temperature, the control unit 140 may be cooled by the temperature adjusting unit 170 so that the temperature of the food and drink is less likely to rise. For example, the control unit 140 heats the food and drink by the temperature adjusting unit 170 so that the temperature acquired by the temperature sensor 160A gradually decreases and falls below a predetermined threshold value so that the temperature of the food and drink is less likely to decrease. You may. For example, the control unit 140 is cooled by the temperature adjusting unit 170 so that when the temperature acquired by the temperature sensor 160A gradually rises and exceeds a predetermined threshold value, the temperature of food and drink is unlikely to rise. You may.

According to the electronic device 100 provided with the temperature adjusting unit 170, it becomes easy to suppress the temperature change of food and drink by heating or cooling by the temperature adjusting unit 170.

In the above embodiment, it has been described that the temperature sensor 160A is provided at the bottom of the coffee cup, for example, but the position where the temperature sensor 160A is provided in the tableware 10 is not limited to this. The temperature sensor 160A may be provided at an arbitrary position where the temperature of the tableware 10 can be detected.

Further, the temperature sensor 160A included in the tableware 10 is not limited to one. The tableware 10 may include two or more temperature sensors 160A. The plurality of temperature sensors 160A may be used for estimating the remaining amount of food and drink in the tableware 10, depending on the arrangement in the tableware 10.

For example, as shown in FIG. 6, the coffee cups of the tableware 10 have different heights on the body (side surface) (in order from the edge side to the bottom side in FIG. 6), the temperature sensors 160a, 160b and 160c. May be equipped. In this case, the electronic device 100 can estimate the remaining amount of the beverage in the coffee cup based on the temperatures detected by the temperature sensors 160a, 160b and 160c. For example, suppose there is hot coffee in a coffee cup. The temperatures detected by the temperature sensors 160a, 160b and 160c are defined as the first temperature, the second temperature and the third temperature, respectively. The electronic device 100 is of a coffee cup, for example, when the second temperature and the third temperature are substantially the same temperature, and the first temperature is lower than the second temperature and the third temperature. It can be estimated that the water surface is higher than the temperature sensor 160b and lower than the temperature sensor 160a. In the electronic device 100, for example, when the first temperature and the second temperature are substantially the same temperature, and the first temperature and the second temperature are lower than the third temperature, the coffee cup It can be estimated that the water surface is higher than the temperature sensor 160c and lower than the temperature sensor 160b. The information regarding the estimated remaining amount may be generated as usage information by the electronic device 100. Here, the substantially constant temperature may include a temperature in which the temperature difference is within a predetermined range (for example, 5 ° C.).

In the above embodiment, the usage state of the tableware 10 may include any state related to the use of the tableware 10 in addition to the state shown in the above-mentioned example. The usage state of the tableware 10 may include, for example, information on whether or not the tableware 10 has been collected from the user, or whether or not the collected tableware 10 has been washed. The usage state of the tableware 10 may include, for example, information on the amount of electricity stored in the electricity storage unit 150 of the electronic device 100 provided in the tableware 10.
