Description

  The present invention relates to a technique for grouping users via a charging device.

  Active exchanges between users who have hobbies and other similarities collaborating (grouping) in the form of so-called “friend registration” and “participating in the community” and notifying the behavior of the partner An Internet service called a social networking service (SNS) has been conventionally provided. In addition, in SNS friend registration, users can publish their own profiles including hobbies and preferences, for example, and perform procedures such as friend application and approval with reference to the public information to link users together.

  Further, even in a web service other than SNS, users can interact with each other in such a manner that, for example, a plurality of blogs to which articles about cats are posted track back each other.

  However, it is troublesome to check the public information of a large number of users one by one in order to search for cooperation partners in such a Web service. Therefore, in Patent Documents 1 and 2, etc., a cooperation recommendation technique between users using mobile terminals is disclosed. Is disclosed. Specifically, these patent documents collect time information and location information from mobile terminals in order to enable users who have approached in the real world to collaborate in a virtual world on a network. A technique for recommending cooperation between users of mobile terminals that are in close proximity to each other is disclosed.

JP 2008-176406 A JP 2006-004318 A

  However, the above-described conventional technique has a problem that position information is necessary to determine that mobile terminals are actually close to each other in the real world. For example, it is conceivable to use GPS (Global Positioning System) to acquire the location information of the mobile terminal, but the GPS function is standardly implemented in all terminals because it needs to receive satellite radio waves. Therefore, the above prior art cannot be used in the case of a mobile terminal that is not equipped with a GPS function and therefore does not have a GPS function.

  As another method of acquiring location information, a method of using location information and identification information of a base station that directly communicates with a mobile terminal may be used, but the base station covers a range of at least a few tens of meters in radius. Therefore, even portable terminals communicating with the same base station at the same time are actually located at a distance of several tens of meters or more and may not be close to each other in the real world.

  In order to solve the above-described problems, the present invention uses a charging device that charges mobile devices with contact / proximity non-contact, and groups mobile devices arranged in a charger at approximately the same time. I will provide a.

  Specifically, a power supply unit that supplies power for charging the portable device via a charger, and a Web that is used when the portable device is used by the portable device during charging. From an ID acquisition unit that acquires a service ID and a user ID in the Web service in association with each other, and from two or more portable devices that are substantially simultaneously supplied to the charger to be supplied with power from the power supply unit. There is provided a charging device including a user ID grouping unit that groups user IDs according to acquired Web service IDs.

  In addition, a first transmission unit that includes the above-described configuration and that transmits a part or all of the grouped user IDs to a server device that manages a Web service identified by the Web service ID that is the grouping source. A charging device is provided. Moreover, the charging apparatus which has a 2nd transmission part which transmits a part or all of grouped user ID with respect to the user's portable apparatus identified with the said grouped user ID is also provided.

  Moreover, it has the said structure, and also has a position holding | maintenance information part which hold | maintains the positional information which shows the position of charging device itself, and the 1st or / and 2nd transmission part match | combines the hold | maintained positional information with user ID. There is also provided a charging device having position information transmitting means for transmitting the information. Moreover, while having a power supply time acquisition part which acquires the power supply time with respect to a portable apparatus in a power supply part, the 1st or / and 2nd transmission part transmits the acquired power supply time together with user ID. A charging device having a supply time transmitting means is also provided.

  According to the present invention configured as described above, users who have approached in the real world in order to charge the mobile device with the charging device without using the location information of the mobile device can be used as a key for Web services on the network. Can be grouped as

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the spirit of the present invention.

  The first embodiment will mainly describe claims 1, 2, 3, 6, and 7. In the second embodiment, claims 4 and 5 will be mainly described.

Example 1
<Overview>
FIG. 1 is a conceptual diagram for explaining an example of user ID grouping processing by the charging device of the present embodiment. As shown in this figure, for example, the charging device of this embodiment is installed in a movie theater. Then, a user who watches a movie in the movie theater places his / her mobile terminal on the charging device after connecting with a chain locked with an anti-theft key (not shown). Then, while charging the mobile device while the user is watching a movie, the charging device according to the present embodiment includes a web service ID such as SNS or online shopping used by the mobile device mounted on the mobile device. The user ID in the Web service is acquired.

  For example, if there is the same Web service ID in the acquired information, the user IDs (user α and user β of the same SNS_A in FIG. 1) are grouped by associating them, and the grouping information is output to the mobile device of the user Or a notification to a server device that manages the Web service.

  In this way, with the charging device of the present embodiment, users α and β using the same Web service in the movie theater at the same time zone can be grouped for the purpose of, for example, linking on the Web service. .

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the charging device according to the present embodiment. The functional blocks of the apparatus described below can be realized as a combination of hardware and software. Specifically, if a computer is used, a CPU (Central Processing Unit), a main memory, a bus, or a secondary storage device (a storage medium such as a hard disk drive, a non-volatile memory, a CD, a DVD, and the like) Read drive, etc.), input devices used for information input, printing equipment and display devices, other hardware components such as external peripheral devices, and interfaces for external peripheral devices, communication interfaces, and control these hardware For example, a driver program, other application programs, and a user interface application. Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or hard disk is processed and stored, An instruction for controlling the software is generated. Alternatively, the functional blocks of this apparatus may be realized by dedicated hardware.

  The present invention can be realized not only as an apparatus but also as a method. A part of the invention can be configured as software. Further, a software product used to cause a computer to execute such software and a recording medium on which the product is fixed are naturally included in the technical scope of the present invention (the same applies throughout the present specification). .

  As illustrated in FIG. 2, the charging device 0200 of the present embodiment includes a power supply unit 0201, an ID acquisition unit 0202, and a user ID grouping unit 0203.

  The power supply unit 0201 has a function of supplying power to the portable device for charging via a charger. For example, a power source or a contact charger for a contact charger, a connection cable or a connector, a contactless proximity Can be realized by a coil mechanism for generating magnetic flux and a power supply program. Thus, the power supply method by the charger is not limited to contact / non-contact, but the distance between the chargers provided in one charging device, the length of the connection cable, the effective range of charging by the magnetic flux, etc. In view of the object of the present invention (grouping between users), a distance that allows the user's portable devices to be close to each other (for example, within a range of several meters in diameter), or a charging device is connected to a movie theater or a convenience store. If it is placed in a facility such as an amusement park, it is preferably within the range of the facility (in the building or on the site).

  The “portable device” is not particularly limited as long as it is a device that can be carried and carried by the user and has a function of connecting to the Web in order to use the Web service as described later. And PHS (Personal Handyphone System), high-function mobile phones (so-called smartphones), notebook computers, tablet computers, and the like.

  The ID acquisition unit 0202 has a function of acquiring a Web service ID used in the mobile device and a user ID in the Web service in association with each other from the mobile device during charging. It can be realized by a memory, a wired or wireless communication circuit, an ID acquisition program, or the like. In addition, a program for transmitting a Web service ID and a user ID to the charging device in cooperation with the ID acquisition unit may be separately installed in the portable device.

  Specifically, a program installed in a mobile device acquires in advance a Web service ID used in the mobile device and a user ID in the Web service, and records and manages them in a flash memory or the like. After that, for example, when the charging start is triggered, the ID acquisition unit of the charging device outputs a transmission request for these IDs to the portable device, and the managed ID is returned from the portable device or to the portable device. The installed program automatically transmits these IDs to the charging device, so that the ID acquisition unit acquires the Web service ID and the user ID.

  Note that “acquire ID upon charging ...” is not particularly limited as long as the ID is acquired during the charging period, and the ID acquisition process is performed at the charging start timing (triggered by the start of the charging process). May be executed, or an ID acquisition process may be executed after a predetermined number of seconds have elapsed since the start of charging. Alternatively, for example, acquisition may be performed simultaneously from mobile devices that are currently being charged at one-minute intervals, regardless of the start of charging of the mobile device.

  “Web service” refers to a service provided via the Internet, and the content of the service is not particularly limited. For example, in addition to the above-mentioned social networking service, Internet shopping service, net auction service, blog and bulletin board Examples include an article posting browsing service, a distribution service for still images / videos / music, and the like.

  FIG. 3 is a diagram illustrating an example of master data for managing the acquired Web service ID and user ID. As shown in FIG. The Web service ID acquired and managed in 001 is “SNS_A”, and the user ID is “user α”. No. The Web service ID acquired and managed at 002 is “SNS_A” and the user ID is “user β”. Further, in this master table, the ID acquisition time (charging start and end times related to acquisition of the ID), identification information of the portable device from which the ID is not shown may be recorded. .

  The user ID grouping unit 0203 has a function of grouping user IDs according to Web service IDs acquired from two or more portable devices that are substantially simultaneously disposed on the charger and are substantially simultaneously powered from the power supply unit. It can be realized by a CPU, a main memory, a user ID grouping program, or the like.

  Note that “grouping of user IDs” refers to managing users identified by the associated user IDs as belonging to the same group by associating two or more user IDs. FIG. 4 is a diagram illustrating an example of user ID master data for managing the grouping of user IDs. As shown in this figure, for example, the user α and the user β are associated and managed as charging the portable device in substantially the same time zone and using the same SNS_A. In addition, the user γ, the user θ, and the user Ω are associated and managed as charging the mobile device in substantially the same time zone and using the same net shopping B, while the user δ is the user θ or the user Ω. The same Internet shopping is used, but the charging of mobile devices is not substantially simultaneous with these users, and the charging time is substantially simultaneous only with the user γ, so it is managed as another grouping. .

  Further, for example, when the charging process and the ID acquisition time are managed together as shown in FIG. Judgment can be made. Alternatively, as described above, when the ID is acquired all at once intermittently, a determination process is not particularly provided, and the portable devices may be arranged substantially simultaneously with respect to the ID acquired simultaneously at the same timing. Alternatively, by detecting the timing of the start of charging and completion of charging (or taking it away from the location for charging), there is a time when there is a mobile device that has not been fully charged or has been taken away (charged or taken away) When the start of charging to another mobile device is detected at the time when there is a mobile device that is not detected), it can also be determined that the mobile devices are arranged almost simultaneously.

  In addition, regarding grouping, it may be determined whether the devices are simultaneously arranged for a certain time or more, and only mobile devices that are simultaneously arranged for a certain long time may be grouped.

  Note that “grouping of user IDs by Web service ID” basically preferably groups user IDs associated with the same Web service ID as described above in view of the object of the present invention. If the service is of a certain relevance for the purpose of the Web service, such as the book shopping Web service X and the book auction Web service Y, or the book posting Web service Z, the X, Y , Z may be grouped together. In that case, separately prepare Web service ID master data that associates Web services that are considered to be highly related in this way, and specify the user ID to be grouped by referring to the Web service ID master data. Good.

  In this way, in the charging apparatus according to the present embodiment, users can be grouped with respect to two or more portable devices that are charged substantially simultaneously by the web service used in the portable device. Therefore, if this grouping information is provided to, for example, a management company or a marketing company of the Web service, for example, in the real world determined from the behavior of the Web service user on the Web service and the installation position of the charger, for example. It is possible to analyze by associating with other actions.

  Also, by notifying each other of the grouping information, it is possible to promote cooperation on the Web service between users who are close to the same time zone for charging in the real world. And about cooperation promotion between users using grouping information, it is good to carry out by the charging device of a present Example further having "the 1st transmission part" which is not illustrated, for example, and performing the following processes.

  The first transmission unit has a function of transmitting a part or all of the grouped user IDs to a server device that manages a web service identified by the web service ID that is the grouping source. It can be realized by a CPU, a main memory, an Internet communication circuit, a first transmission program, or the like.

  FIG. 5 is a diagram illustrating an example of transmission destination master data for performing transmission processing by the first transmission unit. As shown in this figure, for example, IDs of various Web services and destination addresses such as IP addresses of server devices that provide the Web services are recorded in association with each other. Then, the first transmission unit refers to the transmission destination master data, and specifies the IP address of SNS_A as the transmission destination of the grouping information of the user α and the user β that are associated as users of the SNS_A that has been charged substantially simultaneously, for example. The grouping information is transmitted to the IP address.

  In addition, the Web service server device that has received the grouping information uses the information notification function of the Web service to notify each user's in-service account indicated by the grouping information of the ID of the other user. For example, a process that recommends cooperation such as friend registration (for example, message transmission with a friend registration approval button) may be executed.

  In addition, the charging device according to the present embodiment may further include, for example, a “second transmission unit” (not illustrated), and may promote cooperation between users using grouping information by another method.

  The second transmission unit has a function of transmitting a part or all of the grouped user IDs to the mobile device of the user identified by the grouped user ID, for example, CPU, main memory, wired or It can be realized by a wireless communication circuit, a second transmission program, or the like.

  FIG. 6 is a diagram illustrating an example of a notification screen on the mobile device. For example, by using information such as the user ID “user β” and the web service ID “SNS_A” transmitted to the mobile device of the user α, the mobile device uses the information “user β using SNS_A is almost the same as you. At the same time, I charged at the same location.Log in to SNS_A, display information such as “Do you want to apply for friend registration to user β? (Yes) (No)” on the screen, and let user α and user β in SNS_A The recommendation is to recommend collaboration (friend registration, etc.).

<Hardware configuration>
FIG. 7 is a schematic diagram illustrating an example of a configuration of the charging device when the functional components described above are realized as hardware. The operation of each hardware component related to the user ID grouping process will be described with reference to FIG.

  As shown in this figure, the charging device is an ID acquisition unit and a user ID grouping unit, and includes a CPU 0701 for executing various other arithmetic processes and a main memory 0702. In addition, a flash memory 0703 that holds various programs and various master data, a coil 0704 that is a power supply unit in a contactless system, a communication circuit 0705 that performs wireless communication with a portable device, and the like are provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, for example, when it is detected by a contact sensor (not shown) that the portable device is placed on a charging plate or the like, the CPU interprets the power supply program and energizes the coil according to the interpretation result. Then, current is generated in the coil in the portable device due to electromagnetic induction, and charging is executed.

  In addition, for example, when the charging is started as described above, the CPU interprets the ID acquisition program and communicates with the mobile device by wireless ad hoc communication or the like. Then, a request indicating that “the Web service ID used in the mobile device and the user ID in the Web service are output” is transmitted to the mobile device, and is returned in response to the request. The Web service ID and user ID indicated by the response are stored so as to be managed in association with the main memory addresses 1 and 2. Further, when the completion of charging or the removal of the portable device from the charging plate is detected, the ID acquired from the portable device is deleted from the main memory.

  Thereafter, before deleting the ID, when the Web service ID and user ID are similarly received from other portable devices placed on the charging plate and stored in the main memory, the CPU interprets the user ID grouping program. In accordance with the interpretation result, a process for determining whether or not the same Web service ID is stored in a predetermined area of the main memory is executed. When a determination result indicating that the same Web service ID is stored is output, the CPU groups user IDs associated with the same Web service ID and is stored in the flash memory. The user ID is recorded in association with user ID master data as shown in FIG.

  Then, the CPU interprets, for example, a first transmission program (not shown), and identifies the information notification destination address of the management server of the Web service that is a grouping key with reference to transmission destination master data. And it is good to perform the process which notifies grouped user ID with respect to the specified transmission destination address. Then, the Web service server device uses the information transmission function of the Web service to perform processing for transmitting the other user's ID and the like to the in-service account of the notified user, and promotes cooperation between users. Can do.

  Alternatively, the CPU interprets a second transmission program (not shown) and directly performs processing for notifying the mobile device from which the grouped user ID is acquired of the user ID of the other party and the Web service ID that is the grouping key. May be. Then, by a process by a program separately installed in the mobile device, for example, a cooperation recommendation screen as shown in FIG. 6 is displayed on the display of the mobile device, and cooperation between users can be promoted.

  Note that the above example is an example, and as described in the functional configuration, charging may be performed in a wired manner by connecting to a connector, and the ID acquisition timing and the arrangement of chargers in a plurality of portable devices The determination processing of whether or not the web service ID master data is substantially simultaneous, the presence / absence of reference to the Web service ID master data when grouping the user IDs, and the like may be various.

<Process flow>
FIG. 8 is a flowchart illustrating an example of a process flow in the charging device of the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care.

  As shown in this figure, first, power is supplied to the portable device via the charger in accordance with, for example, detection of placement on the charging plate or connection to the connector (power supply step: step S0801). When the mobile device is used for charging, the Web service ID being used and the user ID in the Web service are acquired in association with each other (ID acquisition step: step S0802). ). Then, user IDs are grouped by Web service IDs acquired from two or more portable devices that are substantially simultaneously disposed on the charger and are substantially simultaneously powered from the power supply unit (user ID grouping step: step S0803).

  The grouped user IDs are transmitted to, for example, a server device that manages the Web service identified by the Web service ID that is the grouping source, or the user's portable device identified by the grouped user ID Or send to.

<Brief description of effect>
As described above, with the charging device according to the present embodiment, two or more portable devices that are charged substantially simultaneously can be grouped with each other by the web service used in the portable device. Therefore, by notifying each other of this grouping information, it is possible to promote cooperation on the Web service between users who are close to the same time zone for charging in the real world.

<< Example 2 >>
<Overview>
The present embodiment is based on the charging device having the first transmission unit and / or the second transmission unit of the above-described embodiment, and further transmits the position information of the charging device itself to the Web service management server and portable device. Thus, it is characterized in that it is possible to grasp where “where” the portable devices are charged at substantially the same time. In addition, it is characterized in that it is possible to grasp when the mobile devices are charged at substantially the same time by notifying the power supply time for charging the mobile device together. .

<Functional configuration>
FIG. 9 is a diagram illustrating an example of functional blocks in the charging device according to the present embodiment. As shown in this figure, the charging device 0900 of the present embodiment is based on the above-described embodiment. A transmission unit 0905 is included. In addition, since these structural requirements have already been described in the above embodiment, the description thereof will be omitted.

  The charging apparatus according to the present embodiment includes the position information holding unit 0906, and the first transmission unit and / or the second transmission unit includes the position information transmission unit 0907. Alternatively, the power transmission time acquisition unit 0908 is included, and the first transmission unit and / or the second transmission unit includes a power supply time transmission unit 0909 (in FIG. 9, the first transmission unit is a position information transmission unit). In which the second transmission unit has power supply time transmission means).

  The position information holding unit 0906 has a function of holding position information indicating the position of the charging device itself, and can be realized by, for example, an HDD (hard disk drive), a flash memory, or another storage device. The position information held here may be, for example, latitude / longitude information or other identification information for indicating the position. However, in view of the purpose of promoting cooperation between users, for example, “XX” It is desirable that the place name or facility name be easily recognized by the user, such as “city xx town”, “XX movie theater”, or “restaurant ΔΔ”. Of course, the position information may be held as latitude / longitude information and converted into a place name or a facility name when notifying the user.

  The position information transmission unit 0907 has a function of transmitting the held position information together with the user ID, and can be realized by, for example, a CPU, a main memory, a communication circuit, a position information transmission program, or the like. In this way, by transmitting the location information together with the user ID, the user β who has been charging the user almost simultaneously with you at ““ XX movie theater ”, for example, uses the same SNS_A as you. Do you want to apply for friend registration (Yes) (No) ". Therefore, for example, when applying for a friend, it is possible to communicate with a common topic such as an impression of a movie.

  The power supply time acquisition unit 0908 has a function of acquiring the power supply time for the portable device in the power supply unit, and can be realized by, for example, a CPU, a main memory, a built-in clock, a power supply time acquisition program, or the like. Of course, the power supply time may be acquired by communication from an external server instead of a built-in clock or the like.

  The power supply time transmission unit 0909 has a function of transmitting the acquired power supply time together with the user ID, and can be realized by, for example, a CPU, a main memory, a communication circuit, a power supply time transmission program, and the like. In this way, by transmitting the power supply time together with the user ID, for example, the user β who has been charging almost simultaneously with you at “18:30 today” is the same SNS_A as you. You can make a notification such as “Do you want to apply for friend registration? (Yes) (No)”. Therefore, for example, when the friend application is made, it is possible to communicate with the common topic of the event where the person was at that time.

<Process flow>
FIG. 10 is a flowchart illustrating an example of a process flow in the charging device of the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care.

  As shown in this figure, first, power is supplied to the portable device via the charger in accordance with, for example, detection of placement on the charging plate or connection to the connector (power supply step: step S1001). Then, during the charging, the Web service ID used in the mobile device and the user ID in the Web service are acquired in association with each other from the mobile device (ID acquisition step: step S1002). Then, user IDs are grouped by Web service IDs acquired from two or more portable devices that are substantially simultaneously disposed on the charger and are substantially simultaneously powered from the power supply unit (user ID grouping step: step S1003).

  At the same time, the position information of the charging device itself previously stored in the flash memory or the like is acquired (position information acquisition step: step 1004), and / or the current time information is acquired as the power supply time from, for example, a built-in clock. (Power supply time acquisition step: Step S1005). In addition to the user ID, the location information or / and the power supply time are transmitted to the server device that manages the Web service identified by the Web service ID that is the grouping source (first transmission step: step) In addition to the user ID, the location information or / and the power supply time are transmitted to the user portable device identified by the grouped user ID (second transmission step: step S1007). .

<Brief description of effect>
As described above, the charging device according to the present embodiment can notify the grouped users together with the position of the charging device and the charging time (power supply time). Therefore, when collaborating between users, a topic that matches the position and time can be set as a common topic.
