2. Operation The operation of the information processing system 1 is mainly divided into a posting process and a posting display process. The posting process is a process in which the information processing apparatus 10 transmits posting information to the server 20. The post display process is a process in which the information processing apparatus 10 acquires post information from the server 20 and displays the acquired post information. Details of these processes will be described below. In the following description, software such as a posted information sharing program or a map display program may be described as the main subject of processing. This is because the processing device (CPU 110 or the like) executing the program has other hardware elements. This means that the process is executed in cooperation with.

2-1. Posting Process FIG. 5 is a diagram illustrating a flowchart of the posting process in the information processing apparatus 10A. The flow in FIG. 5 is started when a predetermined operation is performed during execution of the posted information sharing program, for example. Here, a description will be given using an example in which the moving object represents a train.

  The map displayed in this example is a 3D map. A 3D map is a map that includes information about height and is three-dimensionally drawn using this information. In the map program, the angle of the viewpoint for viewing the map (angle with respect to the horizontal line) can be changed according to the user's operation. For example, when displaying a map around a skyscraper, if the angle of the viewpoint is small (low), other buildings behind the skyscraper are hidden behind the skyscraper and cannot be seen. When it is large (high), a part of the building hidden behind the high-rise building can be seen. If the map is rotated, the scene seen from the back of the skyscraper is drawn. The map display reference position (for example, the latitude and longitude of the center of the map) and the scale are specified in advance by the map display program or specified by the user.

  In step S100, the posting information sharing program displays an input screen. The input screen is a screen that prompts the user to input post information.

  FIG. 6 is a diagram illustrating an input screen. In this example, the input screen has an input box 51 and a posting button 52. In this example, a character string (text) is transmitted as post information. The input box 51 is an area for displaying the input character string. The posting button 52 is a button for instructing execution of a process of confirming an input character string as posting information and transmitting the posting information to the server 20. In this example, a plurality of pieces of post information are displayed below the input box 51. In each piece of post information, the user name of the post user and the post time are displayed as corresponding attribute information. The plurality of post information is a so-called timeline displayed in time series.

  Refer to FIG. 5 again. In step S110, the posting information sharing program determines whether the posting button 52 has been pressed. When it is determined that the posting button 52 has not been pressed (S110: NO), the posting information sharing program waits until the posting button 52 is pressed. When it is determined that the posting button 52 has been pressed (S110: YES), the posting information sharing program moves the process to step S120.

  In step S120, the posting information sharing program generates posting information. This posting information includes the character string that has been input to the input box 51 when the posting button 52 is pressed.

  In step S130, the posting information sharing program determines whether to associate the posting information with the moving object. When it is determined that the association is to be performed (S130: YES), the posting information sharing program moves the process to step S140. When it is determined that the association is not performed (S130: NO), the posting information sharing program moves the process to step S150. The determination as to whether or not to perform this association is performed, for example, by one of the following methods (1) or (2).

(1) Judgment according to whether or not the user is on the train In this example, when the user of the information processing apparatus 10A is on the train, the posting information sharing program associates the posting information with the moving object. Judge to do. When the user of the information processing apparatus 10A is not on the train, the posted information sharing program determines that the posted information is not associated with the moving object. Whether or not the user of the information processing apparatus 10A is on a train is determined using, for example, at least one of the following (1a) to (1d).

(1a) Method using position information of information processing apparatus 10A In this example, the position information of information processing apparatus 10A and the position information of a train are collated, and if both match, the user of information processing apparatus 10A Is determined to be on the train. The position information of the current position of the information processing apparatus 10A can be acquired from the GPS receiving unit 180. The position information of the train running near the current position of the information processing apparatus 10 </ b> A is included in the map data provided from the server 30 or the train operation information provided from a server different from the server 30. When both match, the posted information sharing program determines that the user of the information processing apparatus 10A is on the train.

(1b) Method Using Surrounding Sound In this example, when the surrounding sound of the information processing apparatus 10A satisfies a predetermined condition, it is determined that the user of the information processing apparatus 10A is on the train. In this case, the information processing apparatus 10 </ b> A includes a microphone as the input unit 160. The posted information sharing program acquires ambient sounds via the microphone. The posted information sharing program analyzes the acquired sound, and if the sound of a specific pattern (for example, the sound of “Gatangoton” where the train runs) is included, the user of the information processing apparatus 10A gets on the train. Judge that

(1c) Method Using Payment Information In this example, the information processing apparatus 10A uses a payment means (for example, a FeliCa (registered trademark) chip corresponding to mobile Suica (registered trademark) and an application program for mobile Suica to pay a railway fee. ). The posted information sharing program obtains the entrance / exit record of the ticket gate from the settlement means, and determines that the user of the information processing apparatus 10A is on the train when the entrance / exit record indicates that it is in the ticket gate. To do.

(1d) Method Using User Profile In this example, the information processing apparatus 10A uses a user profile. The user profile refers to information including personal information of the user. In this example, the user profile is information indicating whether or not the user has a habit of getting on a train. Specifically, the information includes information indicating a user's daily action history (for example, information indicating where and from where and when moved) and information on a railroad commuter pass (for example, information indicating a boarding section). is there. The posted information sharing program refers to the user profile and the current time and local position, and according to the action history, it is currently a time zone that is moving, and if the current position is located within the boarding section of the boarding pass Then, it is determined that the user of the information processing apparatus 10A is on the train.

  Note that in (1b) to (1d), in order to identify the moving object (train) to be associated with the posted information, the position information indicating the current position of the information processing apparatus 10A and the vicinity of the current position of the information processing apparatus 10A are displayed. The position information of the traveling train may be used. The train position information is included in map data provided from the server 30 or train operation information provided from a server different from the server 30.

  In addition, any one of the methods (1a) to (1d) may not be able to accurately determine whether or not the user is on the train. For example, at a station where many routes are on board, it may be difficult to specify which train the train has been on. Therefore, in order to increase the accuracy of the determination, a plurality of methods (1a) to (1d) may be used in combination.

(2) Judgment according to the operation of the poster In this example, when the user of the information processing apparatus 10A specifies that the posting information is associated with the moving object, the posting information sharing program moves the posting information and the movement. It is determined that the association with the object is performed. When this designation is not made, the posting information sharing program determines that the posting information is not associated with the moving object. In this case, the posted information sharing program has a function of displaying a UI screen for designating correspondence between posted information and a moving object. When specifying the association between the posting information and the moving object, the user calls this UI screen to specify the association.

  In step S140, the posted information sharing program adds information specifying the moving object associated with the posted information (hereinafter, “object specifying information”), that is, information specifying the train on which the user has boarded, to the posted information.

  In step S150, the posted information sharing program transmits (that is, posts) the posted information to the server 20. When it is determined in step S130 that the association is performed, the object specifying information is added to the posting information transmitted to the server 20. When it is determined in step S130 that the association is not performed, the object specifying information is not added to the posting information transmitted to the server 20.

  When the posting information is received from the information processing apparatus 10, the server 20 accumulates the received posting information. That is, the server 20 stores the received posting information in the storage unit 240. At this time, attribute information corresponding to the posted information is also accumulated. The attribute information includes, for example, at least one of a time stamp, a transmission user name, position information, a destination user name, and an application name. The time stamp indicates the time when the posting was made. The transmission user name indicates the user name of the user who transmitted the posting information. The position information indicates a geographical position (for example, latitude and longitude) where the posting has been made. The destination user name indicates the user name of a user designated as a recipient or a viewer of the posted information. The application name indicates the name of the application program that performed the posting process.

  Note that these pieces of attribute information may be added by a client (such as the information processing apparatus 10) to which post information is input, or may be added by the server 20. Moreover, attribute information is not limited to what was illustrated here, Attribute information other than the above may be used.

  In response to a request from the information processing apparatus 10 or another client, the server 20 provides, that is, transmits at least a part of the accumulated posting information to the requesting client. When requesting post information, the client can specify conditions for narrowing down (selecting) post information (for example, the time stamp is XX hour XX minutes XX seconds or later). When the condition is designated, the server 20 selects post information satisfying the designated condition from the accumulated post information and provides it to the client.

  Here, an example has been described in which the information processing apparatus 10 determines whether post information and a moving object are associated with each other, but instead of or in addition to the determination by the information processing apparatus 10, the server 20. May make this determination. This determination is performed, for example, by any of the following methods (3) or (4).

(3) Determination According to Posting Information Analysis Result In this example, the server 20 determines whether or not to associate the posting information with the moving object using the analysis result of the character string included in the posting information. . Specifically, the server 20 analyzes the posting information, and when a specific character string or a combination thereof (for example, a combination of character strings “train” and “ridden”) exists in the posting information, the posting is performed. It is determined that the information is associated with the moving object.

(4) Judgment according to the designation of the administrator In this example, a condition for associating the posting information with the moving object is designated by the manager of the posting information sharing service or the map information display service (that is, the service provider). ing. For example, post information posted by a specific user and including a specific keyword is associated with the moving object. In this case, the moving object associated with the posting information is determined by the administrator. For example, when post information posted by an account of a certain company includes a specific product name of the company, the post information is associated with a moving object of a specific train. This example is useful when advertising a product.

2-2. Post Display Process FIG. 7 is a diagram illustrating a flowchart of a post display process in the information processing apparatus 10B. The flow in FIG. 7 is started when a predetermined operation is performed during the execution of the map display program, for example.

  In step S200, the map display program determines whether an event that triggers updating of the displayed map has occurred. This event is, for example, that the reference position or scale of the map display has been changed, or that a predetermined time has elapsed since the previous update. If it is determined that this event has not occurred (S200: NO), the map display program waits until this event occurs. If it is determined that this event has occurred (S200: YES), the map display program proceeds to step S210.

  In step S <b> 210, the map display program transmits a request for map data to the server 30. This request includes attribute information of the map after display update, for example, a reference position and a scale.

  When the map data request is received from the information processing apparatus 10, the server 30 generates the requested map data. The map data is generated using attribute information included in the request. The map data includes data indicating a moving object of a train that moves within the displayed range. The server 30 transmits the generated map data to the information processing apparatus 10B that is the transmission source of the request.

  In step S <b> 220, the map display program receives map data from the server 30. The map display program stores the received map data.

  In step S <b> 230, the map display program transmits a post information request to the server 20. This request includes a condition for narrowing down post information. Here, this condition includes a condition for limiting the moving object, specifically, an identifier of the moving object included in the map data received in step S220.

  When receiving the post information request from the information processing apparatus 10B, the server 20 selects the post information that satisfies the request from the stored post information. That is, the server 20 selects post information associated with the moving object specified by the identifier included in the request. Furthermore, the server 20 may independently set conditions (for example, the upper limit number of pieces of posted information to be selected) in addition to the conditions included in the request, and may select posted information according to these conditions. The server 20 transmits the selected posting information to the information processing apparatus 10B that is the transmission source of the request.

  In step S <b> 240, the map display program receives post information from the server 20. The map display program stores the received post information.

  In step S250, the map display program displays a map. The map display program moves the moving object on the map. At this time, the map display program moves post information associated with the moving object following the movement of the moving object.

  FIG. 8 is a diagram illustrating a map display example. This map includes a moving object O. Post information P is associated with the moving object. The moving object O moves with the progress of time, and post information P is displayed following the movement of the moving object O.

  Refer to FIG. 7 again. In step S260, the map display program determines whether a condition for canceling the association between the posted information and the moving object is satisfied. If it is determined that the release condition is satisfied, the map display program proceeds to step S270. When it is determined that the release (cancellation) condition is not satisfied, the map display program moves the process to step S200. For example, at least one of the following (1) to (3) is used as the release condition.

(1) Timeout In this example, when the timeout time has elapsed since the display of post information following a moving object has started, the association between the post information and the moving object is released. The timeout time is set by any one of the following (1a) to (1d), for example.

(1a) Fixed time In this example, the timeout time is fixed uniformly. For example, the timeout time is set to 30 seconds, and the association with the moving object is canceled when 30 seconds have elapsed from the start of display of any posting information. In this case, the time-out time is set by the map display program. Alternatively, the server 20 or the server 30 may set a timeout time. When the server 20 or the server 30 sets a timeout time, the server 20 or the server 30 transmits information indicating the timeout time to the information processing apparatus 10.

(1b) Specification by viewer In this example, the timeout time is specified by the user who is the viewer. That is, the map display program has a UI for setting a time-out period for the posted information. The user can specify a timeout time via this UI. That is, in this example, the map display program sets the timeout time.

(1c) Designation by contributor In this example, the timeout time is designated by the user who is the contributor. That is, the posted information sharing program has a UI for setting a timeout time for posted information. The user can specify a timeout time via this UI. That is, in this example, the posting time information is set by the posting information sharing program.

(1d) Designation for each moving object In this example, the timeout time is determined for each moving object. More specifically, it is determined according to the train timetable indicated by the moving object. Conditions related to the timetable for releasing the association with the moving object (for example, displaying only one station, displaying only from one specific station to another specific station, etc.) are determined in advance. The time-out time is determined from the condition and the train timetable indicated by the moving object. For example, when it is determined that the posted information is displayed only between the A station and the B station, if the time when the train arrives at the B station is 13:00, the association with the moving object is 13: A timeout time is set so as to be canceled at 00. In this example, information used for setting the timeout time is included in the map data and the posted information, and the map display program sets the timeout time using these information.

(2) User Behavior In this example, when the user who is the poster gets off the train, the association between the posted information and the moving object is released. In this case, the posting information sharing program of the information processing apparatus 10 </ b> A owned by the user who is the poster monitors the user's behavior even after the posting is finished. The posted information sharing program determines whether or not the user has exited the train by the same method (1a to 1d in section 2-1) as when determining whether or not the user is on the train. When it is determined that the user has got off the train, the posted information sharing program transmits a notification to the server 20 that the user has got off the train. This notification includes the transmission user name and the identifier of the corresponding moving object (the moving object of the train that has just got off).

  When the notification is received from the information processing apparatus 10, the server 20 extracts the user name and the moving object identifier included in the notification. The server 20 extracts post information corresponding to the user name and identifier from the accumulated post information, and deletes information indicating a correspondence relationship with the moving object from the extracted post information.

  In another example, when a user who is a viewer gets off the train, the association between the posted information and the moving object may be released. In this example, it is a premise that post information posted by a user who is on the same train as the user who is a viewer is displayed on the map. In this case, the map display program monitors whether or not the user of the own device gets on or off the train. This monitoring method is as already described (1a to 1d in section 2-1).

  For example, when it is determined that the user has taken the train A, the map display program acquires post information associated with the train A from the server 20, and moves the train A displayed on the map. Move following the object. Thereafter, when it is determined that the user has got off the train A, the map display program cancels the association between the posted information and the moving object (train A), and deletes the posted information from the screen.

(3) Map Position In this example, the map display program releases the association between the posting information and the moving object when the moving object reaches a specific position (for example, a specific station).

  In step S270, the map display program cancels the correspondence between the posted information and the moving object. Further, the map display program performs post-cancellation processing for the posted information. This process is either (a) or (b) below.

(A) Storing Post Information at the Position FIG. 9 is a diagram showing a display example. In this example, the post information whose correspondence relationship with the moving object has been canceled is newly associated with the position (for example, a specific station) where the cancellation has been performed. Specifically, the posting information P is associated with the moving object O. The moving object O goes from the station S1 to the station S3 via the station S2 (the station S1 and the station S3 are not shown). The post information P is set so that the association with the moving object O is canceled at the station S2. While the moving object O moves from the station S1 to the station S2, the posting information P moves following the moving object O. When the moving object O and the posting information P reach the station S2, the correspondence between them is canceled. Thereafter, even if the moving object moves toward the station S3, the posted information P does not follow the moving object O, but remains at the station S2 and is displayed.

(A) Erasing the Display of Post Information FIG. 10 is a diagram showing a display example. In this example, the post information whose correspondence relationship with the moving object has been cancelled is deleted from the display on the map.

  Refer to FIG. 7 again. When the process of step S270 is completed, the map display program moves the process to step S200.

3. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made. Hereinafter, some modifications will be described. Two or more of the following modifications may be used in combination.

3-1. Modification 1
The map displayed in the map display program is not limited to a 3D map. The map display program may display a 2D map as long as it displays a moving object.

3-2. Modification 2
The moving object is not limited to a vehicle. The moving object may be, for example, an element used in weather information (front (rainy season front or cherry blossom front), typhoon, low pressure, etc.). For example, when the moving object indicates a typhoon, post information relating to the typhoon is also moved following the movement of the typhoon.

  In another example, the moving object may indicate a parcel package. In this case, until the package is delivered, the map display program displays only a display indicating that there is post information (for example, “?” Mark) following the moving object, and the package is delivered to the destination. After that, the content of the corresponding post information may be displayed.

3-3. Modification 3
Similar to the cancellation of the association between the moving object and the posting information, the timing for starting the display of the posting information following the moving object may be varied under various conditions. For example, the time from when the map display program receives the posted information to when the posted information is displayed on the map may be a fixed value for all posted times. In another example, the time from when the posted information is received until the posted information is displayed on the map may be specified by the user who is the poster or the user who is the viewer. In yet another example, the time from receiving post information to displaying the post information on a map may be specified for each moving object based on a schedule such as a timetable.

3-4. Modification 4
The function of posting post information to the server 20 and the function of displaying post information acquired from the server 20 may be implemented by a single program. That is, the functions corresponding to the input unit 11, the posting unit 13, the display unit 14, and the display control unit 16 may be implemented by a single program. For example, the map display program described in the embodiment may have a function of inputting and transmitting post information.

3-5. Modification 5
The method for acquiring post information corresponding to a moving object is not limited to that described in the embodiment. When receiving a request for map data from the information processing apparatus 10, the server 30 acquires post information associated with the moving object included in the generated map data from the server 20, and posts the post information together with the map data to the information processing apparatus 10. You may send it. According to this example, the map display program can acquire post information without accessing the server 20.

3-6. Other Modifications The assignment of the functional configuration to the hardware is not limited to that shown in FIG. For example, a server on the network may have a part of what is described as a function of the information processing apparatus 10 in the embodiment. Specifically, a server on the network may have the determination unit 12. In another example, a physically single device may have the functions of the server 20 and the server 30. In still another example, an aggregate of a plurality of devices may have the function of the server 20 or the server 30.

  The hardware configuration of the information processing apparatus 10 is not limited to that illustrated in FIG. For example, the information processing apparatus 10 may have a wireless LAN communication unit that does not have the mobile communication unit 150 and performs communication with a wireless LAN base station. In this case, the information processing apparatus 10 communicates with the server via the wireless LAN communication unit.

  In the above-described embodiment, the program executed by the CPU 110 or the like is a magnetic recording medium (magnetic tape, magnetic disk (HDD, FD (Flexible Disk)), etc.), optical recording medium (optical disk (CD (Compact Disk)), DVD (Digital). Versatile Disk))), a magneto-optical recording medium, and a computer-readable recording medium such as a semiconductor memory (flash ROM or the like). The program may be downloaded via a network such as the Internet.
