BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overview of an information processing system according to one embodiment of the present invention.

An information processing system according to an embodiment of the present invention, as shown in FIG. Configured.
The server 1 and user terminals 2-1 to 2-n are interconnected via a predetermined network N such as the Internet.

Services to which the information processing system of FIG. 1 is applied (hereinafter referred to as "this service") are as follows.
That is, this service is a service for acquiring a log of the movement locus of a car (hereinafter referred to as a "movement log of a car") when a plurality of users ride together and go out by car.
In this embodiment, the server 1 is managed by the provider of this service. Each of the user terminals 2-1 to 2-n is used by each of the n users sharing the car.
The server 1 sequentially acquires information indicating the position of the own terminal (hereinafter referred to as "position information") from the user terminals 2-1 to 2-n. Then, the server 1 generates a movement log of the vehicle based on each piece of position information obtained one by one.
Hereinafter, the user terminals 2-1 to 2-n will be collectively referred to as "user terminals 2" when there is no need to distinguish them individually.
In order to use this service, the user terminal 2 has at least a function of acquiring position information based on information acquired from GPS (Global Positioning System) satellites and transmitting the position information to a server.

Here, when a conventional server acquires movement logs of cars shared by a plurality of users, the conventional server sequentially acquires position information only from one conventional user terminal used by a specific one of the plurality of users. had obtained.
However, for conventional user terminals, acquisition of location information has a high processing load. For this reason, if a plurality of user terminals are gathered together, it has been desired that the plurality of user terminals cooperate to appropriately execute distributed processing of position information acquisition.

Therefore, conditions for acquiring position information are individually applied to each of the user terminals 2-1 to 2-n of this embodiment. Then, the user terminal 2 acquires the position information at the timing when the conditions applied to itself are satisfied. The user terminal 2 transmits the acquired location information to the server 1 .
Here, the condition applied to the user terminal 2 is the case where the position information acquisition order shifts according to the priority assigned to at least some of the user terminals 2-1 to 2-n. , the acquisition order has shifted to its own user terminal 2 . This priority is set, for example, based on the remaining battery level of at least some of the user terminals 2-1 to 2-n (hereinafter referred to as "remaining battery level").
Also, the acquisition order is changed according to the priority every time a predetermined time period elapses.
As a result, for the server 1 of the present embodiment, every time a predetermined period of time elapses, location information is obtained from at least some of the user terminals 2-1 to 2-n from the user terminal 2 whose turn it is to acquire. is sent. Therefore, the server 1 can reliably generate the movement log of the vehicle.
On the other hand, the user terminal 2 does not have to transmit the position information every time the predetermined time elapses, and it is sufficient to transmit the position information only when the acquisition turn, which sequentially shifts according to the priority, comes to itself. In other words, since the transmission interval of the location information of the user terminal 2 is extended, the consumption of the battery can be suppressed.
In this way, when a plurality of user terminals 2 gather together, the plurality of user terminals 2 can work together to appropriately perform distributed processing of position information acquisition.

FIG. 3 is a block diagram showing an example of the hardware configuration of a user terminal as one embodiment of an information processing apparatus to which the present invention is applied in the information processing system of FIG.
The user terminal 2 is appropriately configured by various devices such as a smart phone.
Note that the internal hardware configuration of the user terminal 2 can be basically the same as the configuration of the server 1 except that it has a touch panel and that it has a GPS unit 50. Therefore, here, the configuration of the server 1 Only different points will be explained.

The movement log generation process is a process on the server 1 side, in which location information is acquired from each of the user terminals 2-1 to 2-n and a vehicle movement log is generated based on the location information. A series of processes.

FIG. 4 is a functional block diagram showing an example of a functional configuration for executing location information transmission processing and travel log generation processing among the functional configurations of the server of FIG. 2 and the user terminal of FIG.

In this embodiment, the server 1 manages a website (hereinafter referred to as a “registration site”) where a user registers various information and notifies the server 1 of the registered content. Any of the user terminals 2-1 to 2-n can display this registration site and accept input operations for various registrations.
However, for convenience of explanation, it is assumed that only one of the user terminals 2-1 to 2-n displays the registration site and accepts input operations for various registrations. Such a user terminal 2 is hereinafter referred to as "user terminal 2-A (A is an arbitrary integer value from 1 to n)".
Further, any of the user terminals 2-1 to 2-n operated by n users who are riding in the same vehicle are objects from which position information can be acquired (hereinafter referred to as "acquisition targets"). Here, for convenience of explanation, it is assumed that two user terminals 2 are acquired from the position information to the server 1 . One of the two user terminals 2 to be acquired is the above-described user terminal 2-A. Further, the remaining one user terminal 2 is hereinafter referred to as "user terminal 2-B (B is an integer value different from A and an arbitrary integer value from 1 to n)".

As shown in FIG. 4, in the CPU 41 of the user terminal 2, an acquisition timing determination unit 101, a position acquisition unit 102, a transmission timing determination unit 103, a position transmission control unit 104, a communication control unit 105, display control A unit 106, a priority allocation unit 107, a remaining battery level calculation unit 108, and a registration unit 109 function.

Each of the user terminals 2-1 to 2-n has the functional configuration shown in FIG. 4, but for convenience of explanation, the user terminal 2-A has "A" at the end of each functional block code. , and for the user terminal 2-B, "B" is added to the end of the code of each functional block.
In FIG. 4, a dotted line means that the functional block itself does not function, although the functional block itself is provided. In other words, in user terminal 2-B, priority allocation section 107B and registration section 109B do not function.

The acquisition timing determination unit 101A of the user terminal 2-A is individually applied to each of the acquisition targets (the user terminals 2-A and 2-B in the example of FIG. 4) among the user terminals 2-1 to 2-n. It is determined whether or not the acquisition condition applied to the user terminal 2-A among the acquisition conditions is satisfied. The acquisition timing determination unit 101A determines the timing for acquiring the position information of the user terminal 2-A based on the determination result.
Acquisition conditions are conditions that permit acquisition of location information, and are conditions that are applied independently to each of the user terminals 2-A and 2-B.
Therefore, the acquisition timing determination unit 101B of the user terminal 2-B also determines whether or not the acquisition condition applied to the user terminal 2-B is satisfied. The acquisition timing determination unit 101B determines the timing for acquiring the position information of the user terminal 2-B based on the determination result.

Here, in the present embodiment, as described above, the priority is given to each of the acquisition targets (the user terminals 2-A and 2-B in the example of FIG. 4) among the user terminals 2-1 to 2-n. assigned. For example, it is assumed that the first priority is assigned to the user terminal 2-A and the second priority is assigned to the user terminal 2-B. Also, according to this priority order, the position information acquisition order is shifted every time a predetermined time elapses.
Also, the acquisition condition that the acquisition order has shifted to the user terminal 2-A is adopted for the user terminal 2-A, and the acquisition condition that the acquisition order has shifted to the user terminal 2-B is adopted for the user terminal 2-B. It shall be
Then, in the example of FIG. 4, the acquisition timing determination units 101A and 101B determine the respective priorities of the user terminals 2 to be acquired (user terminal 2-A is first, user terminal 2-B is second), and the time at which acquisition of positional information should be started (hereinafter referred to as "positional information acquisition start time") is acquired from the server 1 in advance.

In this case, the acquisition timing determination units 101A and 101B determine the acquisition timing of the location information for each of the user terminals 2-A and 2-B based on the elapsed time from the location information acquisition start time and the priority.
Specifically, for example, if the transition time of the position information acquisition order is set to every one second, the default acquisition order is the user terminal 2-A with the highest priority. The acquisition start time is determined to be the acquisition timing of the location information of the user terminal 2-A.
When one second elapses from the position information acquisition start time, the acquisition order shifts from the user terminal 2-A with the first priority to the user terminal 2-B with the second priority. Therefore, the acquisition timing determination unit 101B determines that the timing when one second has elapsed from the location information acquisition start time is the acquisition timing of the location information of the user terminal 2-B.
In the example of FIG. 4, since the priority is up to the second place, when two seconds have passed since the location information acquisition start time, the acquisition order is changed from the user terminal 2-B with the second priority to the user terminal 2-A with the first priority. returns (migrate). Therefore, the acquisition timing determination unit 101A determines that the timing when two seconds have passed from the location information acquisition start time is the acquisition timing of the location information of the user terminal 2-A.
The same processing is repeated thereafter, and the timing of 2K seconds (K is an arbitrary integer value including 0) from the location information start time is determined to be the acquisition timing of the location information of the user terminal 2-A. On the other hand, the timing of 2K+1 seconds from the location information start time is determined to be the acquisition timing of the location information of the user terminal 2-B.
In other words, if the server 1 needs to acquire location information every second for generating a movement log of a vehicle, if location information is acquired by one user terminal 2, the acquisition of the user terminal 2 The interval will be 1 second. However, in the example of FIG. 4, since the two user terminals 2-A and 2-B alternately acquire the position information, the acquisition interval of each of the user terminals 2-A and 2-B is up to 2 seconds. be extended. Furthermore, by distributing and acquiring position information among P user terminals 2 (where P is an arbitrary integer value greater than or equal to 3 and less than n), the acquisition interval of each user terminal 2 can be extended to P seconds. be.
In this way, when a plurality of user terminals 2 gather, the plurality of user terminals 2 can work together to appropriately perform distributed processing of position information acquisition.

Position acquisition units 102A and 102B acquire position information of user terminals 2-A and 2-B at the timings determined by acquisition timing determination units 101A and 101B, respectively.

The transmission timing determination unit 103A of the user terminal 2-A determines whether or not a transmission condition different from the acquisition condition described above is satisfied. The transmission timing determination unit 103A determines the timing for transmitting the location information of the user terminal 2-A to the server 1 based on the determination result.
Here, the transmission condition is a condition that permits transmission of position information to the server 1, and is applied independently to each of the user terminals 2-A and 2-B and independently of the acquisition condition. It is a condition to be
Therefore, the transmission timing determination section 103B of the user terminal 2-B also determines whether or not the transmission conditions applied to the user terminal 2-B are satisfied. The acquisition timing determination unit 101B determines the timing for transmitting the position information of the user terminal 2-B based on the determination result.
Although the transmission condition is not particularly limited, here, the condition that the position information has been acquired is adopted. That is, when the positional information is acquired, the positional information is immediately transmitted to the server 1 .

Position transmission control units 104A and 104B transmit the position information of user terminals 2-A and 2-B to communication units 51A and 51B at the timing determined by transmission timing determination units 103A and 103B, respectively. , to execute control to be sent to the server 1 .

Each of the communication control units 105A and 105B executes control for various communications with other devices via the communication units 51A and 51B, respectively.
Other devices correspond to the server 1 and the user terminal 2-B from the user terminal 2-A side, and correspond to the server 1 and the user terminal 2-A from the user terminal 2-B side.

For example, as described above, the server 1 manages a registration site for registering various types of information such as the priority of each user terminal 2 of a user sharing a car.
Therefore, when the user terminal 2-A accesses the registration site, the communication control unit 105A allows the user to access a web page (hereinafter referred to as a "registration page") for registering various information on the registration site. Information necessary for display on the terminal 2 side (hereinafter referred to as "information on the registration page") is acquired via the server 1 and the communication unit 51A.
In this case, the display control unit 106A executes control for displaying the registration page on the display unit 47A based on the information of the registration page.
A specific example of the registration page will be described later with reference to FIG.

Also, the communication control unit 105A executes control for transmitting the priority assigned by the priority assigning unit 107A to another user terminal (for example, the user terminal 2-B).
Furthermore, the communication control unit 105A acquires information about the remaining battery level of each user terminal transmitted from another user terminal (for example, the user terminal 2-B).
In this embodiment, since the user terminal 2-A is a host terminal that registers the priority order, the communication control unit 105A does not transmit information regarding the remaining battery level.
On the other hand, the communication control section 105B of the user terminal 2-B transmits information regarding the remaining battery level calculated by the remaining battery level calculating section 108B to the user terminal 2-A.
Furthermore, the communication control unit 105A executes control for transmitting registration information registered by the registration unit 109A to another user terminal (for example, the user terminal 2-B).
The details of these functional configurations will continue to be explained.

The priority assigning unit 107A assigns each of the user terminals 2 (in this example, the user terminals 2-A, 2- B) assign a priority to each.
As a result, for example, it is possible to assign a lower priority to a user terminal 2 owned by a driver who drives a car because the user wants to keep the battery. Furthermore, as will be described later, if the user terminal 2 is not registered as an acquisition target (excluded from registration), no priority is assigned, so that acquisition of location information can be prohibited.

The remaining battery level calculation unit 108A calculates the remaining battery level of the user terminal 2-A and provides it to the display control unit 106A via the communication control unit 105A.
The remaining battery level calculation unit 108B calculates the remaining battery level of the user terminal 2-B and transmits it to the user terminal 2-A via the communication control unit 105B. In the user terminal 2-A, the remaining battery level of the user terminal 2-B is provided to the display control section 106A via the communication control section 105A.
In this example, as shown in FIG. 5 to be described later, the remaining battery levels of the user terminals 2-A and 2-B are used as a reference when determining the priority of the user terminals 2-A and 2-B. As information, it is displayed on the registration page under the control of the display control unit 106A.
As will be described later, the server 1 side may determine the priority of each of the user terminals 2-A and 2-B. In this case, the remaining battery level calculation units 108A and 108B calculate the remaining battery levels of the user terminals 2-A and 2-B, respectively, and transmit them to the server 1 via the communication control units 105A and 105B, respectively. .

Registration unit 109A receives registration information input by the user via touch operation input unit 46A.
Here, the registration information refers to various types of information that the user has input by operating the user terminal 2 with respect to predetermined items displayed on the registration page as content to be registered when using this service.
Specifically, for example, among the user terminals 2-1 to 2-n, the user terminal 2 or the like from which position information is to be obtained is adopted as one of the registration information as a registered terminal.
In addition, the priority of user terminals 2 (user terminals 2-A and 2-B in this example) registered as registered terminals is adopted as another piece of registration information.
A specific example of a registration page on which predetermined items for entering registration information are arranged will be described later with reference to FIG.

Next, the functional configuration of the server 1 will be explained.
As shown in FIG. 4, in the CPU 11 of the server 1, a position information acquisition section 141, a log generation section 142, and a web management section 143 function.
Furthermore, a location information DB 400 is provided in one area of the storage unit 18 of the server 1 .

When position information is transmitted from at least one of the user terminals 2 (user terminals 2-A and 2-B in this example) belonging to the group set as the acquisition target, the position information acquisition unit 141 , the position information is acquired as position information of the car in which each user of each user terminal 2 rides.

The log generation unit 142 generates a movement log of the vehicle based on the location information of the vehicle (more precisely, the location information of each user terminal 2) sequentially acquired by the location information acquisition unit 141, and generates the location information. It stores in DB400.

The web management unit 143 manages the registration site and executes control for displaying a predetermined page of the registration site, for example, the registration page, on the user terminal 2 (user terminal 2-A in this example) that has accessed the registration site. In addition, the web management unit 143 holds and manages the registration information input on the registration page as information necessary for creating a movement log of the vehicle.

Next, an example of a registration page of a registration site managed by the web management unit 143 will be described with reference to FIG.
5 is a diagram showing an example of a registration page displayed to the user via the user terminal of FIG. 4. FIG.

In the registration page shown in FIG. 5, items of "registered terminal", "remaining battery level", and "ride-sharing distance" are arranged in order from the top.

The user terminal 2 whose position information is to be acquired is input and registered in the item of "registered terminal". For the registered user terminal 2, the box indicating the input item is deleted, and only the name is displayed. That is, in the example of FIG. 6, the user terminal 2-A and the user terminal 2-B are already registered as acquisition targets (user terminals 2 belonging to the group) of the position information.
If the user using the user terminal 2-A wants to add the user terminal 2 from which the location information is to be obtained, enter Any user terminal 2 can be registered.
It should be noted that the user selects desired ones (for example, user terminals 2-A and 2-B) among the already registered user terminals 2 (user terminals 2-A and 2-B in the example of FIG. B) can also be deleted from the acquisition targets.
Also, a common group ID may be assigned to the user terminals 2 (user terminals 2-A and 2-B in the example of FIG. 5) registered as targets for acquiring position information. In other words, a movement log of a predetermined car is generated by the server 1, and the ID indicating the user terminal 2 of each user who shares the predetermined car becomes the group ID. Therefore, each user terminal registered as a target for acquiring position information may transmit the group ID and acquisition time to the server 1 or the like together with the position information.

The remaining battery level of the user terminals 2 (in the example of FIG. 5, the user terminals 2-A and 2-B) that have been registered as targets for acquiring location information are registered and displayed in the item "remaining battery level". .
In this example, the remaining battery level is calculated by the remaining battery level calculation units 108A and 108B of the user terminals 2-A and 2-B, respectively, and the content once transmitted to the server 1 is registered on the server 1 side. and registered in the item of "remaining battery level". However, this is an example, and the calculation results of the remaining battery level calculation units 108A and 108B of the user terminals 2-A and 2-B are directly input to the "remaining battery level" item without going through the server 1. and may be registered. Alternatively, the content manually input by the user to the item of "remaining battery level" on the touch operation input unit 46A may be registered.

The planned travel distance of the car shared by each user is input and registered in the item of "shared ride distance". For example, the acquisition frequency of position information and the like are appropriately changed according to the registered contents.

In the "Priority" item, the priority of each of the user terminals 2 (user terminals 2-A and 2-B in the example of FIG. 5) that have already been registered as targets for acquiring location information is registered and displayed. be done.
The user who uses the user terminal 2-A registers the desired order of priority in the input fields (blank fields) on the right side of each displayed as "user terminal 2-A" and "user terminal 2-B". be able to.
In the example of FIG. 5, the priority of the user terminal 2-A is registered as the first, and the priority of the user terminal 2-B is registered as the second.
Based on the priority order registered here, the acquisition timing determination unit 101 of the user terminal 2 determines which of the user terminals 2 (user terminals 2-A and 2-B in the example of FIG. ) to determine the timing of acquiring each position information.

Next, referring to FIG. 6, a method of acquiring position information based on the priority assigned here will be described.
FIG. 6 is a diagram for explaining an example of a method of acquiring position information using the information processing system of FIG.

In the example of FIG. 6, the server 1 acquires location information transmitted from the user terminal 2-A or the user terminal 2-B at predetermined time intervals.
Here, the user terminal 2-A has the first priority, and the user terminal 2-B has the second priority.
From transmission of location information by the highest priority terminal 2 (user terminal 2-A with the first priority in this example) to transmission by the lowest priority terminal 2 (user terminal 2-B with the second priority in this example) Up to the transmission of location information is said to be "1 course". When one predetermined course ends, the next one course starts. That is, in a predetermined one course, when the lowest priority terminal 2 (in this example, the user terminal 2-B with the second highest priority) obtains the position information and transmits it to the server 1, etc., the predetermined one course ends. do. Then, the next course is started, and the highest priority terminal 2 (in this example, the user terminal 2-A with the highest priority order) acquires the position information and transmits it to the server 1 or the like.

Specifically, when the first course is started, the acquisition order is set to the user terminal 2-A having the highest priority. Therefore, the user terminal 2-A acquires the position information indicating the current position P1 at that time and transmits it to the server 1. FIG. The server 1 receives the location information and stores it in the location information DB 400 .
Next, after a predetermined time has passed, the acquisition order shifts to the user terminal 2-B having the second highest priority. Therefore, the user terminal 2-B acquires the position information indicating the current position P2 at that time and transmits it to the server 1. FIG. The server 1 receives the location information and stores it in the location information DB 400 .
This completes the first course. Then, when the second one course is started, the acquisition order is set to the user terminal 2-A having the highest priority. Therefore, the user terminal 2-A acquires the position information indicating the current position P3 at that time and transmits it to the server 1. FIG. The server 1 receives the location information and stores it in the location information DB 400 .
Thereafter, the same processing is repeatedly executed in units of one course.

As a result, various data including position information are accumulated in the position information DB 400 of the server 1, as shown in FIG.
FIG. 7 is a diagram showing an example of various data stored as a list in the location information DB 400 of the server 1 of FIG. In the list shown in FIG. 7, information on "ID", "acquisition time", "acquisition terminal", and "location information" is stored for each location information. That is, one line of this list corresponds to one predetermined position information.

An “ID” item in a predetermined line stores an identifier (for example, an ID) that can identify the position information corresponding to the line. For example, the ID of the position information corresponding to the first row is "001".
The item "acquisition time" in one predetermined row stores the time when the position information corresponding to the one row was acquired. For example, it can be seen that the position information corresponding to the first row was acquired at "12:00".
In the item "acquired terminal" in one predetermined line, information that can identify the user terminal 2 that has acquired the position information corresponding to the one line (in this example, a code indicating the terminal name), and the user terminal 2 A priority (indicated in parentheses in FIG. 7) is stored. For example, it can be seen that the position information corresponding to the first row was acquired by the user terminal 2-A having the highest priority.
Position information corresponding to the one line is stored in the item of "position information" of one predetermined line. For example, the position information corresponding to the first line is "lat (latitude): 36.35.48, long (longitude): 145.20.30, alt (altitude) 100.2033".
Note that the format of this position information is not particularly limited, and any format may be used as long as it indicates the position of the vehicle for which the travel log is to be generated (more precisely, the position of the user terminal 2 of the user who shares the vehicle). .
The log generation unit 142 of the server 1 generates movement logs of cars shared by a plurality of users (in the example of FIG. 7, FIG. 6 of the car C) can be generated.
In this case, since the server 1 does not need to continuously acquire position information from one user terminal 2, each user terminal 2 (user terminals 2-A and 2-B in the example of FIG. 6) Load distribution processing for position information acquisition is appropriately implemented.

Next, position information transmission processing executed by the user terminal 2 in FIG. 4 will be described with reference to FIG.
That is, FIG. 8 is a flowchart for explaining the flow of location information transmission processing executed by the user terminal 2 of FIG.
In the following example, the processing of the user terminal 2-A will be described, but the same series of processing is also executed for the user terminal 2-B, except that the processing of step S1 is unnecessary.

In step S1, the priority assigning unit 107A of the user terminal 2-A, based on the input content from the user via the touch operation input unit 46A (for example, the input content of the priority order item on the registration page in FIG. 5), A priority is assigned to each of the user terminals 2 (user terminals 2-A and 2-B in the above example) registered as targets for acquiring position information.

In step S2, the acquisition timing determination unit 101A determines whether or not the acquisition condition is satisfied, that is, whether or not the position information acquisition order has shifted to its own user terminal 2-A in this example.
If the acquisition order of the position information has not shifted to its own user terminal 2-A, the acquisition condition is not satisfied, so NO is determined in step S2, and the process returns to step S2.
On the other hand, when the position information acquisition order shifts to its own user terminal 2-A, the acquisition condition is satisfied. Then, the process proceeds to step S3.

In step S3, the position acquisition unit 102A acquires position information from the GPS unit 50A.

In step S4, the transmission timing determination unit 103A determines whether or not the transmission condition is satisfied.
That is, if the transmission condition is not satisfied, it is determined as NO in step S4, and the process is returned to step S4.
On the other hand, if the transmission condition is satisfied, it is determined as YES in step S4, and the process proceeds to step S5.
In this example, since the acquisition of position information is used as a transmission condition, when the process of step S3 is completed, it is immediately determined as YES in step S4, and the process proceeds to step S5.

In step S5, the position transmission control unit 104A transmits the position information acquired in step S3 to the server 1. FIG.

In step S6, the CPU 41 of the user terminal 2 determines whether or not there is an instruction to end processing.
Here, the processing end instruction is not particularly limited, but in the present embodiment, an instruction to shift the user terminal 2 to a so-called sleep state or the like is adopted. That is, as long as the user terminal 2 does not issue an instruction to shift to the sleep state or the like, it is determined as NO in step S6, the process returns to step S2, and the subsequent processes are repeated.
On the other hand, if the user terminal 2 issues an instruction to shift to a sleep state or the like, it is determined as YES in step S6, and the position information transmission process ends.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present invention are included in the present invention. be.

For example, in the above-described embodiment, the remaining battery level calculation unit 108 of the user terminal 2 has been described as performing only calculation of the remaining battery level, but the present invention is not particularly limited to this. For example, the remaining battery level calculation unit 108 may calculate or acquire information such as whether or not the battery is charged, the type of the battery, the year of manufacture, and the like.
Then, the priority of each user terminal 2 may be set based on these pieces of information.

Further, for example, in the above-described embodiment, the information acquired by the user terminal 2 has been described as the positional information of the user terminal 2, but it is not particularly limited to this.
For example, the user terminal 2 may acquire any type of information such as audio information and image information. That is, the present invention is not limited to obtaining location information, but can be applied to obtaining any type of information.

More specifically, in the above-described embodiment, among the user terminals 2-1 to 2-n operated by each user who rides together, there is a group consisting of one or more user terminals 2 registered on the registration page. One or more user terminals 2 (user terminals 2-A and 2-B in the example of FIG. 4) that are recognized and belong to this group are targeted for acquisition.
An acquisition condition (a first condition different from the transmission condition) is individually applied to each acquisition target. As a result, each of the one or more user terminals 2 to be acquired can obtain location information at the timing when the transmission condition applied to its own user terminal 2 among the transmission conditions individually applied to each of the acquisition targets is satisfied. was getting
However, the invention is not specifically limited to such above-described embodiments.
For example, the acquisition target may be each user terminal 2 belonging to a group in which a group including a plurality of user terminals 2 existing simultaneously within a predetermined area is recognized.
In this case, the information acquired by the acquisition target is not particularly limited to positional information, and it is sufficient if it is information of a predetermined type that can be acquired from a predetermined area by the user terminals 2 belonging to the group.
Specifically, for example, in the above-described embodiment, the predetermined area is illustrated as the inside of the car in which the passenger is riding together. Therefore, using the interior of a vehicle as an example, as the information that can be acquired by a plurality of user terminals 2 in the vehicle, information of the context of the vehicle, including the above-described position information, can be adopted.
Here, context refers to all internal and external states of the vehicle. The internal state of the vehicle is a predetermined state distributed in the space direction or time direction (or distributed in any direction) in the vehicle, such as the temperature and noise level (volume of user's voice, music, etc.) in the vehicle. Say. It should be noted that the state of the users in the vehicle (for example, the state of each user's body temperature, heart rate, emotion, etc.) can also be included as the internal state of the vehicle. The external state of the vehicle includes the current position of the vehicle, temperature, weather, surrounding conditions (congestion, etc.), etc., which are distributed in the spatial or temporal direction outside the vehicle (or distributed in any direction). ) refers to a given state.
Furthermore, the interior of the vehicle is merely an example of the predetermined area. In other words, the user terminals 2 belonging to the group do not have to exist in the area of the vehicle, and the user terminals 2 belonging to the group may exist in the area where the same information can be obtained.
In other words, the present invention is applicable when the user terminal 2 to be acquired acquires arbitrary information indicating the internal state and external state (context) of such a predetermined area.

Further, for example, in the above-described embodiments, the timing of acquiring the position information is the timing at which the acquisition condition (the first condition different from the transmission condition) is satisfied. In the above-described embodiment, this acquisition condition (first condition) is such that, in the case where the order of acquisition of position information shifts according to the priority assigned to a plurality of user terminals 2, the order of acquisition of position information is Although it has been adopted that the user terminal 2 has been transferred to its own user terminal 2, it is not particularly limited to this.
For example, the acquisition timing determination unit 101 determines the acquisition condition in advance based on the travel distance of the carpool, and determines the timing for acquiring the position information assuming that the acquisition condition is satisfied when the travel distance exceeds a certain distance. You can judge.

Further, for example, in the above-described embodiment, the method of shifting the acquisition order according to the priority is performed each time a predetermined period of time elapses, but the method is not particularly limited to this.
For example, the user terminal 2 whose turn it is to acquire the information transmits information indicating that the acquisition of the positional information has been completed (the positional information itself may be sufficient) to the server 1, and the server 1 determines the order of acquisition based on the information. A method of notifying the user terminal 2 of the acquisition order after the migration to that effect may be employed.

Also, for example, in the above-described embodiment, the method of allocating the priority is the method of allocating the priority based on the contents of the manual input from the user by the user terminal 2-A, but it is not particularly limited to this.
That is, the priority assigning unit 107 may be delegated from the user terminal 2 to the server 1 . In this case, the server 1 may appropriately acquire various information such as the remaining battery level of each user terminal 2 and automatically set the priority of each user terminal 2 based on the acquired various information.
In other words, the assignment of the priority order described above does not necessarily have to be determined based on the remaining battery level, and other factors such as the communication environment of the user terminal 2 may be taken into consideration.
The communication environment here includes both the communication environment for the user terminal 2 to transmit the location information to the server 1 and the GPS supplementation situation (the communication environment for acquiring the location information).
The former communication environment corresponds to a carrier for communication by the user terminal 2, a network environment such as network traffic, and the like. For example, as in the above-described embodiment, if the condition that the location information has been obtained is adopted as the transmission condition, in other words, if the acquisition of the location information and the transmission to the server 1 are continuously performed, A priority order may be assigned to each user terminal 2 so that the user terminal 2 having a good network environment for data transmission and reception is allowed to continuously acquire the location information and transmit the data to the server 1 .
In addition, from the viewpoint of the GPS supplementation situation (communication environment for acquiring position information), in order to improve the accuracy of position information, priority is assigned according to whether or not each user terminal 2 can acquire GPS. may
Here, priority allocation does not need to be fixed, and may be updated as needed. That is, the network environment may be monitored and the priority assignment updated based on the network environment. Also, for example, the priority allocation may be updated for each course.

Also, for example, in the above-described embodiment, the position information is obtained at predetermined time intervals (for example, every 1 second), but the present invention is not particularly limited to this. For example, the acquisition interval (acquisition frequency) may be freely changed.
Also, as a method for changing (changing) the acquisition interval, for example, the following method is conceivable.
For example, the acquisition frequency can be changed by controlling whether or not to assign the above-described “priority order” (controlling whether the user terminal 2 is to be acquired or not to be acquired).
Further, for example, the acquisition frequency can be changed by changing the above-described "acquisition condition" itself.
Also, for example, the acquisition frequency can be changed by controlling whether to permit or prohibit information acquisition for each “timing when the acquisition condition is satisfied” without changing the above-mentioned “acquisition condition” itself. .
Note that when the acquisition interval is 0, it means that acquisition of position information is stopped (prohibited).

Furthermore, in the above-described embodiment, the position information is transmitted to the server 1 each time it is obtained, but the present invention is not particularly limited to this.
That is, the user terminal 2-A can collectively transmit to the server 1 the location information acquired over a plurality of times.
Also, for example, the user terminal 2-B may transmit the acquired position information to another information processing terminal (for example, the user terminal 2-A). In this case, the user terminal 2-A can collectively transmit the location information of a plurality of user terminals 2 (for example, the user terminals 2-A and 2-B) to the server 1. FIG. Specifically, for example, when the user terminal 2-B acquires Q pieces of position information, the Q pieces of position information may be collectively transmitted to the user terminal 2-A. Then, in the user terminal 2-A, 2Q pieces of position information (Q pieces of position information acquired by the user terminal 2-A and Q pieces of position information transmitted from the user terminal 2-B) are collectively sent to the server 1. can be sent to
In other words, the timing of acquiring the position information and the timing of transmitting the position information can be separated independently.

Also, for example, when the user terminal 2 acquires location information, if the change in location indicated by a plurality of location information acquired in the past is less than a certain amount, the acquisition interval of location information may be decreased.
Specifically, if the degree of change in location information is small (below a threshold value) as a result of multiple measurements, the user terminal 2 may stop acquiring location information. Alternatively, instead of the user terminal 2 stopping acquisition, the interval for acquiring location information may be increased, or a switch may be made so that only the user terminal 2 with the highest remaining battery level acquires location information.
Further, after that, when the degree of change in the position information becomes large, the original process can be returned as the process of acquiring the position information.
Such a method is effective, for example, when the car to be shared is stuck in a traffic jam.
Further, for example, the user terminal 2 may recognize the route of movement based on the position indicated by the position information acquired in the past, and change the acquisition interval of the position information according to the type of the route.
Specifically, when the vehicle travels along a route that is fixed to some extent, such as an expressway, there is no need to increase the frequency of acquiring position information. Therefore, when the car is traveling on a highway, it is possible to widen the interval of position information acquisition. Whether or not the vehicle got on or off the expressway can be determined based on ETC (automated toll payment system) information and location information.
On the other hand, when there are various route options such as general roads, the position information acquisition interval may be shortened.
Furthermore, as the information for changing the acquisition frequency described above, not only past location information, but also current location information or future location information (prediction information) may be employed.
In other words, the route of movement may be recognized based on the position indicated by the position information acquired in the past or present, or the predicted future position, and the frequency of acquisition may be changed according to the type of route. good.

Further, for example, although the description is omitted in the above-described embodiment, the following measures may be taken as measures for GPS accuracy.
That is, when the server 1 acquires location information that is a predetermined distance or more away from the previously acquired location, the server 1 may also acquire location information from other user terminals 2 and correct the movement log of the car.
Here, the predetermined distance may be a fixed value, or may be variable so as to correspond to the speed based on the movement log so far. Also, the position information may be acquired sequentially except for the user terminal 2 whose position information is not accurate.

Further, for example, in the above-described embodiment, the registration means (eg, display of a registration page) for registering the user terminal 2 whose position information is to be obtained is provided in the user terminal 2 (eg, user terminal 2-A) that serves as the host. Although the description has been given as a specific example, the present invention is not particularly limited to this.
That is, the registration means may be provided in the server 1 or another user terminal (for example, the user terminal 2-B). When the server 1 includes the registration means, for example, any user terminal (for example, the user terminal 2-C not shown) simply accesses the server 1 and is automatically registered as the user terminal 2. You can also

Further, for example, in the above-described embodiment, the items to be registered on the registration page are described as "registered terminal", "remaining battery level", "movement distance", and "priority", but are not particularly limited to this.
That is, it is possible to include user information (including information other than registered terminals) of each user who rides in the car, availability of charging, whether the user is a driver, information acquisition interval, whether the user has already boarded the vehicle, and the like.

Further, for example, although not described in the above-described embodiment, the process of determining the order of acquiring position information and the number of times of acquisition can be executed in advance.
That is, the user terminal 2 may acquire from the server a registration page that can be referred only to users who share the same car, display the registration page, and set the order and number of times of information acquisition on the registration page.
Also, for example, as described above, the registration page displays the remaining battery level of each user terminal 2 and information about the ride-sharing distance. may be obtained at a higher interval. Specifically, for example, while the user terminal 2 with a low remaining battery level acquires the information once within a certain period, the user terminal 2 with a large remaining battery level may acquire the information three times.
Alternatively, for example, the same user terminal 2 acquires the position information until the remaining battery level falls below a predetermined value, and when the remaining battery level falls below the predetermined value, the user terminal 2 with the next priority order acquires the position information. good. In this case, if the remaining battery levels of all user terminals 2 are below a predetermined value, the predetermined value may be lowered.

Further, for example, in the above-described embodiment, the position information acquired by the position acquisition unit 102 is used for creating a movement log of the vehicle without correction or the like, but the present invention is not particularly limited to this.
That is, when the position indicated by the position information acquired this time is a predetermined distance or more away from the position indicated by the position information acquired in the past (a distance at which it is physically impossible to move), the position information is received from another user terminal 2. may be obtained to correct the position information obtained this time.

Further, for example, in the above-described embodiment, the user may get in or out of the vehicle while sharing the vehicle, although the explanation is omitted.
In such a case, the user terminal 2 or the server 1 newly registers or deletes the user terminal 2 from which position information is to be obtained, so that the user terminal 2 from which position information is to be obtained can be dynamically changed.

For example, the case where the user gets on the train halfway is the following case.
Specifically, for example, when four people board at maximum and only three people share a ride at the time of departure, the user terminals 2 of the three people acquire the position information at the time of departure. After that, when a fourth person rides together, the four user terminals 2 acquire the position information.
If a fourth person rides with you, you can log into the above registration page and re-determine your priorities. In that case, for example, the process of acquiring position information (one course) can be restarted.
Alternatively, when a fourth person rides with the user, the server 1 transmits information specifying the acquisition start time and the acquisition time interval to the fourth user terminal 2, and the other three user terminals 2 receive the acquisition interval A notification is sent to update the
In this case, instead of restarting the position information acquisition process, the acquisition interval may be changed while the acquisition process up to that point is continued, and the fourth user terminal 2 may be interrupted as an acquisition target.
As for the timing of the fourth person riding together, if the user terminal 2 is pre-registered on the registration page, it is possible to notify the server 1 of riding together (addition of acquisition target) by tapping a predetermined button in the registration page. Alternatively, the server 1 may change settings such as an acquisition interval in response to the notification.
Also, based on the location information of the user terminal 2 of the fourth user and the location information of the other user terminals 2, the server 1 or the user terminal 2 automatically determines that the fourth user has started riding together. Alternatively, the information may be acquired by four people. Alternatively, for example, the server 1 or the user terminal 2 acquires the position information of the fourth user terminal 2 and the other user terminals 2 at the same time multiple times, and if the position information at each time of acquisition matches , it may be determined that the fourth user has started riding together.

Further, for example, the case where the user gets off is the following case.
When a user gets off the car on the way, the priority order can be determined again on the server 1 side by notifying the server 1 of getting off the car. In that case, for example, the position information acquisition process may be restarted.
Alternatively, when any user gets off the vehicle, the server 1 may send a notification to update the acquisition interval to the remaining user terminals 2 . In this case, instead of restarting the position information acquisition process, the acquisition interval may be changed while continuing the position information process up to that point.
The timing of getting off the vehicle can be notified to the server 1 by tapping a predetermined button on the registration page, and the settings such as the acquisition interval may be changed from the server 1 according to the notification.

Furthermore, when the user gets on or off the car during the above-mentioned carpooling, it is possible to automatically determine the boarding/alighting status of the user who is taking the carpool.
That is, it is possible to automatically determine the boarding/alighting status of the user based on the position of the user terminal 2 by GPS.
For example, when one user (or multiple users) is separated from the position of another user (co-rider) by a certain amount or more, it is determined that the user (or multiple users) has exited the vehicle. can do.
Further, for example, the position information of the user terminal 2 of the user who has boarded the vehicle and the position information of the user terminal 2 of the other user are obtained a plurality of times, and when the position information at each time of acquisition matches, riding together is started. It can also be determined that
Further, for example, the user boarding/alighting information described above can also be confirmed by short-range wireless communication (for example, Bluetooth (registered trademark) or NFC (registered trademark)) between the user terminals 2 .
Note that when the user newly gets on and off the vehicle by any of the above-described methods, a new priority may be determined using the above-described registration page. In this case, the server 1 and the user terminal 2 may newly start the process of acquiring the position information, or interrupt the new user terminal 2 as an acquisition target while continuing the process of acquiring the position information up to that point. You can let
Note that the method of determining whether the user gets on or off the vehicle is not particularly limited to the above example. Alternatively, for example, a method of determining whether the user gets on or off the vehicle may be adopted by confirming through short-range communication between the user terminals 2 .

Also, for example, the series of processes described above can be executed by hardware or by software.
In other words, the functional configuration of FIG. 4 is merely an example and is not particularly limited.
That is, it is sufficient that the information processing system has a function capable of executing the above-described series of processes as a whole, and what kind of functional blocks are used to realize this function is not particularly limited to the example in FIG. Also, the location of the functional block is not particularly limited to that shown in FIG. 4, and may be arbitrary. For example, in the above-described embodiment, the priority assigning unit 107, the registering unit 109A, etc. functioning on the user terminal 2-A side may be delegated to the server 1. FIG.
Also, one functional block may be composed of hardware alone, software alone, or a combination thereof.

Further, for example, when a series of processes is executed by software, a program constituting the software is installed in a computer or the like from a network or a recording medium.
The computer may be a computer built into dedicated hardware.
Further, the computer may be a computer capable of executing various functions by installing various programs, such as a server, a smart phone, a personal computer, or various devices.

Further, for example, a recording medium containing such a program is not only constituted by a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to the user, but also is pre-installed in the device main body. It consists of a recording medium, etc. provided to the user in the

In this specification, the steps of writing a program recorded on a recording medium are not only processes that are performed chronologically in that order, but also processes that are not necessarily chronologically processed, and that are performed in parallel or individually. It also includes the processing to be performed.
Further, in this specification, the term "system" means an overall device composed of a plurality of devices, a plurality of means, or the like.

In other words, the information processing system to which the present invention is applied can take various embodiments having the following configurations.

For example, in a state in which a group including a plurality of information processing terminals existing simultaneously within a predetermined area is recognized, one information processing terminal belonging to the group (for example, a user terminal in FIG. 1 existing simultaneously within a predetermined area such as a car) In the user terminal 2-A) when the user terminals 2-A and 2-B in FIG. 4 exist in the group registered on the registration page among 2-1 to 2-n,
The plurality of information processing terminals at a timing when a first condition (for example, the acquisition condition described above) applied to the own information processing terminal among the conditions individually applied to each of the plurality of information processing terminals is satisfied. Acquisition means (for example, position acquisition unit 102A in FIG. 4) for acquiring a predetermined type of information (for example, position information) that can be obtained from the predetermined area if
control to transmit the acquired information of the predetermined type to an information processing device outside the group (for example, the server 1 in FIG. 1 or FIG. 4) or another information processing device among the plurality of information processing terminals; a transmission control means to be executed (for example, the position transmission control unit 104A in FIG. 4);
Prepare.

As a result, in a place where a plurality of information processing terminals gather, the plurality of information processing terminals can work together to appropriately perform distributed processing of information acquisition.

Here, further comprising determination means (for example, the acquisition timing determination unit 101A in FIG. 4) for determining whether the first condition is satisfied,
The acquiring means can acquire the predetermined type of information at the timing when the determining means determines that the first condition is satisfied.
That is, it is possible to control the timing at which the information processing terminal acquires a predetermined type of information such as position information.

Here, the transmission control means performs control to transmit the predetermined type of information to the another information processing device at a timing when a second condition different from the first condition (for example, the transmission condition described above) is satisfied. can be executed.
That is, the timing of acquiring predetermined types of information such as position information and the timing of transmitting the information can be individually changed, so that a system with a higher degree of freedom can be constructed.
Specifically, when location information is adopted as the predetermined type of information, the timing of transmitting the location information to the server may be each acquisition as in the above-described embodiment, or may be during the acquisition period. It is good also as every predetermined period longer than. In the latter case, the information processing terminal can collectively upload a plurality of pieces of information acquired within the predetermined period.
Alternatively, for example, the timing of transmitting the position information to the server may be the point in time when the movement to the moving route is completed. Also in this case, the information processing terminal can collectively upload a plurality of pieces of information acquired until the vehicle finishes moving.
Furthermore, the destination of information acquired by a predetermined information processing terminal (for example, the user terminal 2-B in FIG. 4) is not the server 1 but another information processing terminal (for example, an information processing terminal owned by a driver). , the user terminal 2-A) in FIG. The transmission format in this case is also not particularly limited, and a transmission format using short-range communication such as Bluetooth (registered trademark) or NFC (registered trademark) can be adopted. In this case, the information processing terminal owned by the driver can collectively upload data collected from other information processing terminals to the server.

Here, the first condition is a case where the acquisition order of the predetermined type of information shifts in accordance with the priority assigned to each of at least some of the plurality of information processing terminals. has migrated to its own information processing terminal.
That is, since each of the plurality of information processing terminals targeted by this service can change the information processing terminal from which predetermined types of information such as positional information is acquired can be changed in a constant cycle, each information processing terminal can continuously (Vehicles in which multiple users are carpooling) can appropriately obtain information.
Note that "at least some of the plurality of information processing terminals" does not necessarily mean that all of the plurality of information processing terminals operated by each of the plurality of users who are riding together do not need to be targets for acquiring the predetermined type of information. It means. For example, an information processing terminal with a very low remaining battery level may be excluded as a target for acquiring predetermined types of information and may not be assigned a priority.

Here, the transition of the acquisition order according to the priority in the first condition can be performed each time a predetermined period of time elapses.
As a result, predetermined types of information such as positional information can be appropriately obtained every time a predetermined period of time elapses, so that a log of the obtained information, for example, a movement log of a car, can be generated more appropriately.

Here, it is possible to further include priority assigning means for assigning the priority to each of at least some of the plurality of information processing terminals.
Alternatively, the separate information processing apparatus may be provided with priority assigning means for assigning the priority to each of at least some of the plurality of information processing terminals.

Here, the priority assigning means can assign the priority based on the remaining battery level of each of at least some of the plurality of information processing terminals.
That is, since the priority order for acquiring predetermined types of information such as location information can be assigned based on the remaining battery level, the predetermined types of information can be sequentially acquired while considering the remaining battery level of each information processing terminal. can continue. As a result, a log of these acquired information, for example, a movement log of a car, is appropriately generated.

Here, the priority assigning means can assign the priorities based on communication environments of at least some of the plurality of information processing terminals.
That is, since the priority order for acquiring predetermined types of information such as positional information can be assigned based on the communication environment, the predetermined types of information are sequentially obtained while considering the communication environment of each information processing terminal. be able to. As a result, a log of these acquired information, for example, a movement log of a car, is appropriately generated.
As described above, the communication environment includes the communication environment when acquiring a predetermined type of information such as location information, and the communication environment when transmitting the acquired information to a server or other information processing terminal. It is a concept that includes both
Specifically, for example, generally, a low priority can be assigned to an information processing terminal with a poor communication environment.

Here, the priority assigning means
determining one or more targets to which the priority is assigned from among the plurality of information processing terminals;
The priority can be assigned to the object.
In other words, since it is not necessary to assign priority to all registered information processing terminals, it is possible to flexibly perform processing such as not acquiring position information from an information processing terminal whose battery is rapidly depleted, for example.

Here, the acquisition means can acquire position information indicating the position of the information processing terminal of itself as the predetermined type of information.

Here, the obtaining means can change the frequency of obtaining the position information in a predetermined case.
That is, since the interval for acquiring position information can be freely changed, for example, when the remaining battery level of the registered information processing terminal is generally low, it is possible to reduce the interval for acquiring position information. processing becomes possible.
