  The network 40 relays communication. The network 40 may include two or more sub-networks. For example, the network 40 includes a mobile communication network and the Internet.

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.

  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 posted information sharing program specifies the altitude of the information processing apparatus 10A. For example, at least one of the following (1) to (3) is used for specifying the altitude.

(1) Method 1: Method Using Location Information FIG. 7 is a diagram illustrating a flowchart of Method 1. In the method 1, the altitude of the information processing apparatus 10A is specified using the position information. This method is effective when the position (latitude and longitude) and the altitude have a one-to-one correspondence, for example, when the altitude is determined by a natural topography such as a mountainous area.

  In step S1311, the posting information sharing program acquires position information (latitude and longitude) of the information processing apparatus 10A from the GPS receiving unit 180A. In step S1312, the posted information sharing program transmits a request for altitude information to a predetermined server on the network 40 (hereinafter referred to as "altitude information server", not shown). This request includes the position information acquired in step S1311.

  The altitude information server has a database in which position information and corresponding altitude information are recorded. When receiving the request for altitude information, the altitude information server extracts altitude information corresponding to the position information included in the received request from the altitude information recorded in the database. The altitude information server transmits a response including the extracted altitude information to the information processing apparatus 10A that is the transmission source of the request.

  In step S1313, the posted information sharing program receives a response from the advanced information server. In step S1314, the posted information sharing program extracts altitude information from the received response. Thus, the posted information sharing program acquires altitude information corresponding to the position information. That is, the altitude of the information processing apparatus 10A is specified.

(2) Method 2: Method Using Identification Information of Wireless LAN Base Station FIG. 8 is a diagram illustrating a flowchart of Method 2. In the method 2, the altitude of the information processing apparatus 10A is specified using the identification information of the wireless LAN base station. This method is effective when the position (latitude and longitude) and altitude do not necessarily correspond one-to-one, for example, when the user is in a high-rise building. Here, a case where the user of the information processing apparatus 10A is in a high-rise building will be described as an example. In this high-rise building, a wireless LAN base station is provided on each floor. The information processing apparatus 10A communicates with a wireless LAN base station installed on the current floor, that is, a wireless LAN base station with the highest radio field intensity.

  In step S1321, the posted information sharing program acquires the identification information of the wireless LAN base station with which it is communicating via the wireless LAN communication unit 190. As the identification information of the wireless LAN base station, for example, an SSID (Service Set Identifier) is used. In this example, the SSID is named according to a predetermined rule. This rule stipulates that information specifying the floor on which the wireless LAN base station is installed should be included.

  In step S1322, the posted information sharing program specifies the floor on which the wireless LAN base station is installed from the acquired identification information. The posted information sharing program identifies the floor according to the above rules. Thus, the posted information sharing program identifies the altitude of the information processing apparatus 10A (in this example, the floor (for example, the 36th floor)).

  The identification information of the wireless LAN base station is not limited to SSID. Any information that can identify the wireless LAN base station may be used. Further, the specific method for specifying the altitude from the identification information is not limited to the above example. For example, the information processing apparatus 10 </ b> A may acquire the altitude information via the network 40 from a server having a database that records the correspondence between the identification information of the wireless LAN base station and the altitude information.

(3) Method 3: Method for Analyzing Post Information FIG. 9 is a diagram illustrating a flowchart of Method 3. In Method 3, the altitude is specified by analyzing the posted information. This method is effective when Method 1 and Method 2 cannot be used.

  In step S1331, the posted information sharing program transmits a request for analyzing the posted information to a predetermined server on the network 40 (hereinafter referred to as “posted analysis server”). This request includes post information to be analyzed.

  The post analysis server analyzes post information and generates altitude information corresponding to the post information. This analysis includes, for example, analysis of a character string. For example, altitude information indicating the altitude corresponding to the top of Mt. Fuji is generated from the posted information including the character string “I am at the top of Mt. Fuji!”. Alternatively, altitude information indicating the altitude corresponding to the 36th floor of the building is generated from the posted information including the character string “I am drinking coffee on the 36th floor of the building”. The post analysis server transmits a response including the generated altitude information to the information processing apparatus 10A that is the transmission source of the request.

  In step S1332, the posted information sharing program receives a response from the posted analysis server. In step S1333, the posted information sharing program extracts altitude information from the received response. Thus, the posted information sharing program acquires altitude information corresponding to the position information. That is, the altitude of the information processing apparatus 10A is specified.

  Refer to FIG. 5 again. In step S140, the posting information sharing program adds altitude information indicating the altitude specified in step S130 to the posting information. In step S150, the posted information sharing program transmits the posted information to which the altitude information is added 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, altitude 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 altitude information indicates the altitude at which 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.

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

  In step S200, the map display program displays a map. 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 S <b> 210, 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 position, specifically, the reference position of the currently displayed map and the distance from the reference position. The distance from the reference position is determined according to the scale of the currently displayed map. For example, the distance from the reference position is the radius of the inscribed circle of the currently displayed map.

  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. In addition to the conditions included in the request, the server 20 uniquely sets conditions (for example, the upper limit number of pieces of posted information to be selected), and selects 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> 220, the map display program receives post information from the server 20.

  In step S230, the map display program narrows down (selects) post information to be displayed on the map from the received post information. In this example, the posted information is narrowed down based on the altitude of the own device (information processing apparatus 10B). For example, any of the following (1) to (3) is narrowed down.

(1) Narrowing example 1: Narrowing by altitude range based on the altitude of the own aircraft In this example, altitude information indicating the altitude range based on the altitude of the own aircraft, for example, the altitude of the own aircraft ± 10 m is added. Posted information is selected. That is, post information posted by a user who is relatively at the same height as or close to him / her is displayed.

  FIG. 11 is a diagram showing an outline of narrowing down according to narrowing example 1. Here, an example is shown in which a map centering on the position of the own machine is displayed on the mountainside where the own machine is located. A mark (in this example, a star (★)) is displayed at the position of the aircraft. Post information is displayed in a balloon on the map. The apex of the triangle drawn from the balloon indicates the position where the posting information is posted. Displayed is post information posted by a user at an altitude of ± 10 m. In this example, post information such as “A little more to the summit! Let's do our best!” And “I'm tired ...” is displayed.

(2) Narrowing example 2: Narrowing based on the field of view of the user of the own device In this example, posted information posted from the position corresponding to the field of view of the user of the own device (that is, the position corresponding to the region of the field of view) Post information with information added) is selected. That is, post information posted by a user who is relatively at the same height as or close to him / her is displayed.

  FIG. 12 is a diagram showing an outline of narrowing by narrowing example 2. Here, an example is shown in which a map centering on the position of the own device is displayed on the east side of the mountain where the own device is located. In this example, since there is a summit portion, the field of view is not open on the west side of the aircraft, and only the region on the east side of the aircraft (shaded area in the figure) is open. What is displayed is post information posted from within the shaded area. In this example, post information such as “The lake on the right is beautiful!” And “Where is the front city?” Is displayed.

  The field of view from the position of the own device is specified by a map display program, for example. The map display program identifies the field of view from the altitude information included in the map and the position of the own device.

(3) Narrowing example 3: Narrowing by the altitude range designated by the poster In this example, the posted information to be displayed includes information for designating the altitude range of the viewer as attribute information. In addition, post information whose altitude is included in the altitude range designated by the contributor is selected. For example, when the own device is currently located at a point of 1000 m above sea level in a certain mountain, posted information including an altitude of 1000 m in the designated altitude range of the viewer is displayed. As a specific example, post information in which “950 to 1050 m” is specified as the altitude range of the viewer is displayed, but post information in which “1200 m or more” is specified is not displayed.

  FIG. 13 is a diagram showing an outline of narrowing by narrowing example 2. Here, an example is shown in which a map centering on the position of the own machine is displayed on the mountainside where the own machine is located. What is displayed is post information in which the altitude of the own device (information processing apparatus 10B) is included in the specified altitude range. In this example, post information such as “How do you see here from the height?” And “Oh, here!” Is displayed.

  Refer to FIG. 10 again. In step S240, the map display program displays post information selected by narrowing down on the map. In this example, the map display program changes the appearance of the posted information according to the height indicated by the altitude information added to the posted information. Examples of the appearance to be changed include the size of the display area (Display Example 1) and the darkness of the characters (Display Example 2).

  FIG. 14 is a diagram illustrating Display Example 1. In this example, posted information with higher altitude indicated by corresponding altitude information is displayed larger (posted information with lower altitude is smaller).

  FIG. 15 is a diagram illustrating a second display example. In this example, the post information with a higher altitude indicated by the corresponding altitude information is displayed darker (the post information with a lower altitude is lighter). In both display examples 1 and 2, by adopting these methods, the height relationship of the position where the posted information is linked becomes clearer.

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 The function of posting posted information to the server 20 and the function of displaying posted 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 acquisition unit 14, and the display 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.

3-2. Modification 2
The server on the network may have a part of what is described as the function of the information processing apparatus 10 in the embodiment. For example, a server on the network may have the adding unit 12. In this case, the information processing apparatus transmits the post information to the server 20 without adding altitude information. More specific description will be given below.

  FIG. 16 is a flowchart showing a posting process according to the second modification. Steps S100 to S120 are common to the processes of steps S100 to S120 in the flow of FIG. Detailed description is omitted.

  In step S330, the posted information sharing program transmits the generated posted information to the server 20. The server 20 specifies the altitude of the information processing apparatus 10 when the posted information is posted with respect to the posted information transmitted from the information processing apparatus 10. The advanced specifying method is the same as the methods 1 to 3 (FIGS. 7 to 9) described in the embodiment. That is, at least one of a method using position information, a method using identification information of a wireless LAN base station, and a method of analyzing post information is used.

3-3. Modification 3
The posted information may not be displayed on the 3D map. For example, the posting information may be displayed on a screen without a map.

  FIG. 17 is a diagram illustrating a display example 3. In this example, the posted information is displayed not by the map display program but by the posted information sharing program. That is, the 3D map is not displayed, and the same UI screen as in FIG. 6 is displayed. In the example of FIG. 6, a plurality of pieces of posted information are displayed in time series, whereas in the example of FIG. 17, the plurality of pieces of posted information are arranged in the order of height. In each posting information, as the corresponding attribute information, the user name of the posting user and the altitude (geographical altitude) at the time of posting are displayed together.

3-4. Other Modifications The method for specifying the altitude of the information processing apparatus 10 is not limited to that described in the embodiment. For example, the information processing apparatus 10 may include an altitude sensor and specify the altitude using a measurement result obtained by the altitude sensor. Alternatively, the posting information sharing program may cause the information processing apparatus 10 to display a UI screen for allowing the user to input the current altitude, and the information processing apparatus 10 may specify its own altitude based on the altitude input by the user. .

  The conditions for narrowing down posted information are not limited to those described in the embodiment. Any condition may be used as long as it uses altitude information. For example, a condition that the posted information is posted from a position higher than or lower than the current altitude of the information processing apparatus 10 of the user who is the viewer of the posted information may be used. Alternatively, post information may be narrowed down by a condition using information different from the altitude information (for example, user name, time stamp, keyword, position information, etc.) in addition to the condition using altitude information.

  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. For 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.
