Also, the server device 100 may be an information processing device that provides some kind of web service online to the terminal device 10 of each user U. FIG. For example, the server device 100 provides web services such as Internet connection, search service, SNS (Social Networking Service), electronic commerce (EC), electronic payment, online game, online banking, online trading, accommodation/ticket reservation, Services such as video/music distribution, news, maps, route search, route guidance, route information, operation information, and weather forecast may be provided. In practice, the server device 100 may cooperate with various servers that provide web services as described above, mediate the web services, or take charge of the processing of the web services.

Note that the server device 100 can acquire user information about the user U. FIG. For example, the server device 100 acquires information about attributes of the user U, such as the user U's sex, age, and area of residence. Then, the server device 100 stores and manages identification information indicating the user U (user ID, etc.) and information related to the attributes of the user U. FIG.

In addition, the server device 100 acquires various types of history information (log data) indicating actions of the user U from the terminal device 10 of the user U or from various servers based on the user ID or the like. For example, the server device 100 acquires the position history, which is the history of the location and date and time of the user U, from the terminal device 10 . The server device 100 also acquires a search history, which is a history of search queries input by the user U, from a search server (search engine). In addition, the server device 100 acquires a viewing history, which is a history of content viewed by the user U, from the content server. The server device 100 also acquires a purchase history (payment history), which is a history of product purchases and payment processing by the user U, from an electronic commerce server or a payment processing server.

In this embodiment, the terminal device 10 is a charging target that can be charged by wireless power supply. The server device 100 predicts the chargeable time from the information of the user U who possesses (owns or carries) the terminal device 10 to be charged, and adjusts the charging capability of wireless power supply. For example, the server device 100 predicts the chargeable time from the context of the user U, and adjusts the charging capability of wireless power supply to the terminal device 10 .

Note that the terminal device 10 is merely an example. In fact, it may be a charging target that can be carried by a user U other than the terminal device 10 . For example, the charging target may be a portable music player, a smart speaker, a wireless device, a small electronic device, or the like, which can be charged by wireless power supply.

For example, a user U carrying a terminal device 10 enters a store (or facility) equipped with wireless power supply. The server device 100 specifies (identifies) each user U who is in the store, estimates the stay time of each user U, and concentrates the charging capacity as the stay time of the user U becomes shorter. The user U's terminal device 10 is rapidly charged.

At this time, the server device 100 cooperates with the wireless charging device 200 in the store. A plurality of wireless charging devices 200 are installed in the store. If the terminal device 10 of the user U is in the store space, it can be charged from the wireless charging device 200 . For example, it is a spatial transmission type wireless power transmission system.

[1-1. Operation example]
As shown in FIG. 1, the server device 100 collects user information about each user U in the store (step S1). In the case of a store such as a fast food store where the customer pays for the product first and then receives the product (prepaid store), the payment information at that store may be used as the user information. The server device 100 may receive the payment information at the store from the store terminal, or may receive it from an electronic payment application or the like of the terminal device 10 .

Next, the server device 100 specifies (identifies) each user U from the collected user information (step S2). For example, the server device 100 specifies (identifies) the user U from the user ID indicating the user U included in the user information. At this time, the server device 100 may specify (identify) the user U who is the owner of the terminal device 10 based on the information (terminal information, user information, etc.) obtained from the terminal device 10 in the store. good. Alternatively, the server device 100 may use identification information (member information, card information, etc.) of each user U acquired in the store, and/or face image recognition or fingerprint authentication (biometric authentication) of each user U in the store. ) or the like, the user U who is the owner of the terminal device 10 may be specified (identified).

Next, the server device 100 estimates the context of each user U from the collected user information (step S3). At this time, the server device 100 acquires attribute information, history information, etc. of the user U based on the user ID included in the collected user information user information, and determines the context of the user U from these information. can be estimated. For example, the server device 100 estimates the context of the user U from the identified user U's search history, browsing history, average stay time, past stay time, schedule, and the like. In addition, the server device 100 estimates the context of the user U from various information (sensor information, etc.) obtained by the terminal device 10 in the store, cameras and microphones installed in the store, or various sensor devices. may

Then, the server device 100 adjusts the charging capability for the charging object possessed by the user U according to the estimated context of the user U (step S4). In this embodiment, the terminal device 10 of the user U is charged. However, in practice, it may be a charge target other than the terminal device 10 owned by the user U (other than the terminal device 10). The server device 100 may set in advance the priority of a plurality of charging targets possessed by the user U, based on the user U's prior setting. Moreover, the server device 100 may determine the priority of the charging target based on the context of each charging target. For example, the server device 100 may adjust the charging capability so that the charging target with the highest frequency of use or the charging target with the lowest remaining battery level (remaining battery capacity) is charged in order. Since the remaining battery level varies depending on how the user U uses the charging target and the charging timing, it can be said that the user U's context. It should be noted that the charging capacity may be adjusted so that charging is performed in order from the charging target with the lowest battery capacity, regardless of the remaining battery capacity. The battery capacity can be said to be the user U's context because it varies depending on the charging target owned by the user U.

[1-2. machine learning]
In this embodiment, the server device 100 may estimate the context of the user U by machine learning when estimating the context of the user U who has visited the store. For example, the server device 100 learns the combination of the user U, the store, and the user U's usual behavior (staying time, time until leaving the store, etc.) in the store, and analyzes the user U's context. Create a model to estimate (infer) Then, the server device 100 uses the model to estimate the context of the user U when the user U enters one of the stores.

It should be noted that even for the same user U, the behavior of the user U (staying time, time until leaving the store, etc.) may differ depending on the store used, the day of the week, the time of day, etc., when the store is used. is expected. For example, if the user U is at a store near his workplace during the morning hours on weekdays (when he goes to work), the length of stay is short. etc.), it is expected that the length of stay will be longer. Therefore, the server device 100 may estimate the context of the user U by taking into account information on date and time (day of the week and time period). For example, the server device 100 stores the user U, the store, the date and time when the user U uses the store, and the behavior of the user U in the store (stay time, time until leaving the store, etc.). Create a model for learning combinations and estimating (inferring) the user U's context. Then, the server device 100 uses the model to estimate the context of the user U when the user U enters one of the shops.

In addition, even for the same user U, depending on the presence or absence of a companion (one or a group) and the type of companion (friend, dating partner, family, boss, colleague, business partner, etc.) It is expected that U's behavior (stay time, time until leaving the store, etc.) may vary. Therefore, the server device 100 may estimate the context of the user U, taking into account information about the other person who is present. For example, the server device 100 learns a combination of the user U, the store, the other person who attends the same seat, and the behavior of the user U in the store (staying time, time until leaving the store, etc.), Create a model to estimate (infer) the context of U. Then, the server device 100 uses the model to estimate the context of the user U when the user U enters one of the stores. Further, the information is not limited to the information about the other person who is present, and may be the information about the purpose of use of the store (private or business).

Further, the server device 100 may share (unify) the models of the users U belonging to the same segment. That is, the server device 100 creates a common model for users U belonging to the same segment. For example, the server device 100 shares models of users U who have the same attributes or who take the same actions.

[1-3. Example〕
For example, the server device 100 estimates the time until the user U leaves the store as the context of the user U from the user U's search history, browsing history, average staying time, past staying time, schedule, etc. do. The time until leaving the store may be the stay time from entering the store to leaving the store, or the remaining time obtained by subtracting the elapsed time after entering the store from the expected stay time, or the current time. It may be the difference (remaining time) from the time to the expected closing time. Specifically, the server device 100 estimates the time until each user U in the store leaves the store, and uses the estimated time until the store leaves as a context, and the shorter the time until the store leaves, the higher the time. to charge capacity.

At this time, the server device 100 controls the wireless charging device 200 that transmits electric power by transmitting radio waves, and strengthens the directivity of the radio waves of the wireless charging device 200 toward the terminal device 10 of the user U. For example, the server device 100 directs the antenna for outputting radio waves of the wireless charging device 200 toward the terminal device 10 of the user U. FIG. Note that if wireless charging device 200 is movable, server device 100 may move wireless charging device 200 itself. Moreover, if possible, the server device 100 may increase not only the directivity of the radio wave but also the output of the radio wave (output power, radio wave intensity).

Also, a contact-type wireless charger or the like may be used instead of the wireless charging device 200 . For example, the server device 100 concentrates power on the wireless charger charging the terminal device 10 of the user U whose remaining time is short, and controls (adjusts) such that the wireless charger rapidly charges the terminal device 10. You may

In addition, the server device 100 adjusts the charging capability of each user U's terminal device 10 according to the relative context of each user U in the store. That is, the server device 100 changes the radio wave directivity of the wireless charging device 200 based on the context of the user U so that the terminal device 10 of the user U with relatively shorter remaining time is preferentially charged. do.

At this time, the server device 100 directs the radio wave of the wireless charging device 200 toward the terminal device 10 of the user U whose time to leave the store is expected to be shorter among the terminal devices 10 of each user U. to strengthen At this time, server device 100 adjusts the direction in which wireless charging device 200 outputs radio waves so that more power is supplied to users who leave the store earlier. For example, if the server device 100 has three transmission devices in a store, and there are user A (1 hour until leaving the store) and user B (10 minutes until leaving the store), one terminal device of user A is used. The direction in which the wireless charging device 200 outputs radio waves is adjusted so that the user B's terminal device is charged.

Further/or, the server device 100 may adjust the charging capability of the terminal device 10 of each user U according to the remaining battery level of the terminal device 10 of each user U in the store. For example, if there is no significant difference in the time until each user U leaves the store, the server device 100 considers the current battery level of each terminal device 10, The radio wave directivity of the wireless charging device 200 may be changed so that the terminal device 10 of U is preferentially charged.

At this time, the server device 100 strengthens the directivity of the radio waves of the wireless charging device 200 in the direction of the terminal device 10 having a smaller remaining battery level among the terminal devices 10 of each user U. For example, if the server device 100 has three transmission devices in a store, and there are user A (80% remaining battery charge) and user B (30% remaining battery charge), one terminal for user A is The direction in which the wireless charging device 200 outputs radio waves is adjusted so that the device is charged and the terminal device of the user B is charged.

In addition, the server device 100 stores the terminal device of each user U according to the store visit history and the number of visits (the visit history and number of visits to the facility) of each user U, the purchase amount of goods, the number of times the service is used, and the like. 10 may be adjusted. For example, the server device 100 changes the radio wave directivity of the wireless charging device 200 so as to charge the terminal device 10 of the user U who has visited the store relatively many times and the total amount of purchases of products relatively large. You may

[1-4. others〕
When the server apparatus 100 implements a combination of wired power supply and wireless power supply in the store, the terminal apparatus 10 that uses the wired power supply may be excluded or targeted. It can be realized by adjusting the power of wired power supply. Further, if the terminal device 10 can be charged by combining wired power supply and wireless power supply, the server apparatus 100 may increase the directivity of the terminal apparatus 10 that is being charged only by wireless power supply.

Furthermore, the server apparatus 100 may accept settings related to the model that the user wishes to charge when entering an area where wireless power supply is possible. At this time, when the user U is selected as a charging target user when entering an area where wireless power supply is possible, the user U sets in advance which model the user U wants to charge. For example, the user U preliminarily sets that he wants the smartphone to be wirelessly powered, but does not want the smartwatch to be wirelessly powered.

The server device 100 may exclude devices that the user U has previously excluded from being charged. For example, the server device 100 adjusts the direction in which the wireless charging device 200 outputs radio waves so as to avoid devices that the user U has previously excluded from charging.

When the user U owns a plurality of devices, the server device 100 may be adjusted to charge each of the plurality of devices of the user U preferentially. Adjustments may be made so that (the device that takes the longest time to charge) is preferentially charged.

The server device 100 may follow the user U when the user U moves. For example, the server device 100 adjusts the direction in which the wireless charging device 200 outputs radio waves according to the movement of the user U's terminal device 10 .

Based on the presetting of each user U, the server device 100 separately charges a device that is desired to be charged using radio waves (directivity) (charging desired) and a device that is not desired to be charged (no charging required) for each user. do.

The server device 100 prioritizes each user U, not each terminal device 10 . For example, the server apparatus 100 estimates that "this user U will stay long", "this user U will leave in 5 minutes", etc. The direction in which the wireless charging device 200 outputs radio waves is adjusted so that the terminal device 10 of the person U is preferentially charged.

Also, the server device 100 may charge an electric vehicle or the like outside the store (outdoors) instead of the terminal device 10 in the store. That is, the power supply method of the present embodiment may be applied to an electric vehicle, a drone, or the like to be charged. In this way, it can also be applied to charging electric vehicles and the like.

In addition, server device 100 performs processing related to control (adjustment) of wireless charging device 200 . Therefore, by applying this embodiment, it is possible to charge 20 units even if the remaining capacity is 10 units.

For example, when each terminal device 10 is charged with full power, Xw (watts) is required for each device. , 10 terminals can be charged. However, when the server device 100 controls the remaining power when charging each terminal device 10 (for example, when there are many terminal devices that do not need to be charged much), the power supplied to each terminal device is reduced to 0.5Xw. , it becomes possible to charge 20 terminal devices in parallel.

Also, as a store, because of the electric capacity of the same clay pipe, even if normally only three wireless charging devices 200 can be installed, about 20 wireless charging devices can be installed.

Further, when one of the two charging targets is charged to 95% and the other charging target has only about 5% remaining, the server apparatus 100 determines which of the two charging targets has the smaller remaining battery level at that time. Adjust to send a strong radio wave to the charging target to rapidly supply power.

[1-5. Dynamic pricing of wireless power supply]
The server apparatus 100 may add the accuracy (reliability) of the prediction in addition to the user U's predicted leaving time (rechargeable time) to the metrics.

As a result, for example, it is not only estimated that the store will leave after 7 hours, but it is also estimated to be 10% after 1 hour, 60% within 2 hours, and so on. It becomes possible to determine the power supply amount.

In addition, the server device 100 can charge 10 yen per hour if it is predicted that the store will be closed within 6 hours, but will charge 100 yen per hour if the store is expected to be closed within 30 minutes. You may let

For example, when providing a service such as a wireless power supply portal, the charge rate may be changed with respect to the time until the customer leaves the store. Also, if the user stays at the store for an hour longer for the power supply, the store is also profitable, so offset (compensate, offset) with the income from the store. may
