Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[A: Outline of the embodiment]
FIG. 1 is a diagram illustrating an outline of the present embodiment. The posted information posted by the user may be associated with the posted position. In the present embodiment, it is possible to intentionally make the posting position ambiguous. By doing so, it is possible to avoid the inconvenience caused by the user's home, work place, or other location being known to a third party. In FIG. 1, the number of posted information for each predetermined area is displayed on the map M of a certain area using the object R1. The object R1 is a display element in which numbers are circled. This number indicates the number of posted information posted in the corresponding area.

It is not necessary to obscure the posting position for all posted information. For example, the object R2 means that the position specified by the object R2 (hereinafter referred to as "reference position") can be used as the posting position. When the posting information is posted by selecting the object R2, the reference position specified by the object R2 becomes the posting position. When the object R1 or R2 is selected by the user, the posting information posted at the posting position corresponding to the selection is displayed in a list (in this example, the timeline display) as shown on the screen SC.

[B: Configuration of Embodiment]
FIG. 2 is a diagram showing an overall configuration of a posting information system 1 according to an embodiment of the present invention. The posting information system 1 is a system that executes processing based on the posted information. In the present embodiment, the posted information is the posted information related to the SNS, and is the posted information posted by the user who uses the SNS. The posted information includes a message consisting of characters, symbols, etc., but may also include elements such as images and photographs.

The posting information system 1 includes a plurality of terminal devices 10 and a posting information server 20. The plurality of terminal devices 10 and the posting information server 20 communicate via the communication line NW. The communication line NW is, for example, a public communication line including the Internet and a wireless communication network. However, the type of communication line NW is not particularly limited. Further, the communication line NW may be either wired or wireless. Although only two terminal devices 10 are shown in FIG. 2, there are actually more terminals 10.

The plurality of terminal devices 10 are used by users who use SNS. Although the terminal device 10 is a smartphone in FIG. 2, it may be a terminal device having a communication function and a display function, such as a tablet computer. Further, the terminal device 10 may be a wearable terminal (for example, a wristwatch type terminal) worn on a part of the user's body, or a non-portable terminal device (for example, a desktop computer device). The posting information server 20 is a server device that stores the posting information posted by the user in the posting information DB (Data Base) 210. The posted information DB 210 corresponds to the storage unit of the present invention. The posted information DB 210 is realized by using, for example, a storage device exemplified by a hard disk.

FIG. 3 is a diagram showing an example of the configuration of the terminal device 10. As shown in FIG. 3, the terminal device 10 includes a control unit 11, a communication unit 12, a UI (User Interface) unit 13, a positioning unit 14, and a storage unit 15.
The control unit 11 controls each unit of the terminal device 10. The control unit 11 includes a processor including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) as arithmetic processing units. The CPU controls each unit of the terminal device 10 by reading the program stored in the ROM or the storage unit 15 into the RAM and executing the program. The communication unit 12 communicates with the posting information server 20 via the communication line NW. The communication unit 12 includes, for example, a wireless communication circuit and an antenna. The UI unit 13 interacts with the user. Specifically, the UI unit 13 includes a display unit 131 and an input unit 132. The display unit 131 displays an image on the display surface. The display unit 131 includes, for example, a liquid crystal display. The input unit 132 accepts the input of information from the user. The input unit 132 includes, for example, a touch panel provided on the display surface of the display unit 131 and physical buttons. The input unit 132 may include a microphone for receiving voice input. The positioning unit 14 measures the position of the terminal device 10 (that is, the position of the user of the terminal device 10) and generates position information indicating the measured position. The positioning method is, for example, a GPS (Global Positioning System) method. In this case, the positioning unit 14 includes a circuit and an antenna for receiving GPS signals. The storage unit 15 stores a program executed by the control unit 11 and data necessary for executing a process described later. The storage unit 15 includes, for example, a flash memory.

FIG. 4 is a diagram showing an example of the configuration of the posted information DB 210. In the posting information DB 210, each of the plurality of posting information is stored in association with the posting position and the time of posting. The "posting position" indicates the position of the terminal device 10 when the terminal device 10 posts (transmits) the posted information to the posting information server 20. “At the time of posting” indicates the time when the terminal device 10 posted the posted information (more specifically, the date and time). However, in the posting information DB 210, posting information that is not associated with the posting position may be included.

FIG. 5 is a diagram showing an example of the functional configuration of the terminal device 10. The control unit 11 of the terminal device 10 includes a posting position setting unit 111, a presentation unit 112, a posting information generation unit 113, a posting unit 114, a limiting position setting unit 115, a position specifying unit 116, and an acquisition unit 117. , And the display control unit 118. Each function of the control unit 11 is realized by the cooperation of the processor and the program executed by the processor.

The posting position setting unit 111 sets the posting position. The presentation unit 112 divides the map into a plurality of mesh areas and presents the map to the user using the display unit 131. The posting position setting unit 111 can set the mesh area selected by the user from the mesh areas presented by the presentation unit 112 at the posting position. The posting position setting unit 111 can also set the above-mentioned reference position as the posting position.

FIG. 6 is a diagram illustrating a mesh region of the present embodiment. The left part of FIG. 6 shows the mesh area when the scale is relatively small, and the right part of FIG. 6 shows the mesh area when the scale is relatively large.
The mesh region of this embodiment is realized by the method disclosed in http://geogames.net/geohex/v3. One mesh area identifies a geographical location, here an area on a map. The mesh area is presented on the map by the presentation unit 112. As can be seen from FIG. 6, one mesh area corresponds to a narrower area as the scale of the map is larger, and corresponds to a larger area as the scale of the map is smaller. The mesh area of the present embodiment is used to obscure the posting position or set the position on the map.

The post information generation unit 113 generates post information based on the information input by the user using the input unit 132. The posting unit 114 associates the posting information generated by the posting information generation unit 113 with the posting position set by the posting position setting unit 111, and posts the information to the posting information server 20. Specifically, the posting unit 114 transmits the posting information and the posting position to the posting information server 20 using the communication unit 12.

The restricted position setting unit 115 sets a restricted position for restricting posting by the posting unit 114. In the present embodiment, the restricted position setting unit 115 sets a "restricted area" which is an area for restricting posting. The posting unit 114 restricts posting when the posting position is included in the restricted position, that is, belongs to the restricted area. "Restriction on posting" means to prevent posting that should be done, such as prohibition of posting and deletion of a part of information contained in posted information. The process of issuing a warning to the user or asking the user for confirmation before posting is also included in the "posting restriction" because this process hinders the posting for the user. The restricted position setting unit 115 sets the restricted area based on the information input by the user using, for example, the input unit 132.

The location identifying unit 116 identifies a geographical location. The position specifying unit 116 specifies which post information associated with the post position is to be acquired from the post information server 20. The position specifying unit 116 specifies a geographical position, and in the present embodiment, an area on a map (hereinafter referred to as “acquisition area”).

The acquisition unit 117 communicates with the posting information server 20 using the communication unit 12 to acquire the posting information from the posting information DB 210. The acquisition unit 117 acquires the posted information according to the geographical position (that is, the acquisition area) specified by the position identification unit 116. At this time, the acquisition unit 117 acquires a predetermined number of posting information in the order in which the posting time is closer to the predetermined reference time among the posting information including the posting position according to the acquisition area.

The display control unit 118 causes the display unit 131 to display the posted information acquired by the acquisition unit 117. Specifically, the display control unit 118 displays the object corresponding to the posted information at a position corresponding to the posted position on the map. Further, when an object is selected, the display control unit 118 causes the display unit 131 to display the posting information corresponding to the object. Further, when the acquisition area is selected, the display control unit 118 causes the display unit 131 to display the posted information corresponding to the acquisition area.

[C: Operation of the embodiment]
<C-1: Operation at the time of posting>
FIG. 7 is a flowchart showing a process executed by the terminal device 10 at the time of posting.
Before creating the posted information, the restricted position setting unit 115 determines whether to set the restricted area (step S1). If it is determined as "NO" in step S1, the process of the terminal device 10 proceeds to step S3. This is the flow of processing when the user thinks that it is not necessary to set the restricted area.

On the other hand, if it is determined as "YES" in step S1, the restricted position setting unit 115 sets the restricted area (step S2). FIG. 8 is a diagram illustrating a procedure for setting a restricted area. In this example, the map M of the area designated by the user is displayed on the display unit 131. Further, the presentation unit 112 divides the map M into a plurality of mesh regions by the method described with reference to FIG. 6 and presents the map M. The soft buttons B1 to B5 with the numbers "1" to "5" shown in FIG. 8 are buttons for changing the scale of the map. In this embodiment, the scale is smaller in the order of the soft buttons B1, B2, B3, B4, B5. The upper part of FIG. 8 shows a state in which the soft button “B2” is selected. When the user selects one of the mesh areas, the restricted position setting unit 115 sets the restricted area based on this mesh area. Here, it is assumed that the restricted position setting unit 115 sets the mesh areas T11, T12, T17, and T18 as the restricted area, as shown in the lower part of FIG. For example, a specific area is set as a restricted area in order to prevent a third party from grasping the user's home, neighborhood, work place, and the like.
When the scale of the map is changed, the mesh area presented by the presentation unit 112 also changes with the change. Further, an upper limit may be set on the number or size of restricted areas that can be set by one user. This is to prevent too many places where posting is restricted. Moreover, the type of scale may be 4 or 6 or more.

It will be described back to FIG.
Next, the posting information generation unit 113 generates posting information based on the information input by the user using the input unit 132 (step S3). When the restricted area is set in step S2, it is not necessary that the setting of the restricted area and the generation of the posted information are a series of processes. For example, by saving the restricted area once set by the restricted position setting unit 115, the posting information may be generated at any time after the restricted area is set.
Next, the posting position setting unit 111 determines whether or not to obscure the posting position (step S4). In the present embodiment, when the posting position is ambiguous, the posting position is set using the mesh area. If the posting position is not ambiguous, the posting position shall be set using the reference position described in FIG.

If "YES" is determined in step S4, the presentation unit 112 presents a mesh area as a candidate for the posting position using the display unit 131 (step S5). 9 and 10 are diagrams showing a method of presenting a mesh region as a candidate for a posting position. FIG. 9 shows a mesh region when the scale is relatively small, and FIG. 10 shows a mesh region when the scale is relatively large. As shown in FIG. 9, for example, the presentation unit 112 presents the mesh region T1 to which the position positioned by the positioning unit 14 on the map M belongs. Further, the presentation unit 112 presents the mesh regions T11 to T16 adjacent to the mesh region T1. The mesh regions T11 to T16 are meshes that share one side with the mesh region T1. When the scale is changed and the scale is increased, the presentation unit 112 presents the display unit 131 to the mesh area T2 to which the position positioned by the positioning unit 14 on the map M1 belongs, as shown in FIG. 10, for example. .. Further, the presentation unit 112 presents the mesh regions T21 to T26 adjacent to the mesh region T2. The mesh regions T21 to T26 are meshes that share one side with the mesh region T2, respectively. The user's current position is likely to belong within the mesh area T1 or T2. However, the position measured by the positioning unit 14 may include an error. Therefore, we have adopted a mechanism that allows the user to select the mesh area corresponding to the current position. Here, it is assumed that the user has selected the mesh area T1.

It will be described back to FIG.
The posting position setting unit 111 sets a mesh area selected by the user from the mesh areas that are candidates for the posting position as the posting position (step S6). Here, the posting position setting unit 111 sets the mesh area T1. Next, the posting unit 114 determines whether or not the set posting position is within the restricted area (step S7). The restricted area here is the mesh areas T11, T12, T17, T18. Therefore, the posting unit 114 determines “NO” in step S7. Then, the posting unit 114 transmits the posting information associated with the mesh area T1 as the posting position to the posting information server 20 using the communication unit 12 (step S8).

If it is determined in step S7 that the area is within the restricted area (step S7; YES), the posting unit 114 restricts posting of posted information. Here, the posting unit 114 restricts posting when any of the mesh areas T11, T12, T17, and T18 is set as the current position in step S6. For example, as shown in FIG. 11, the posting unit 114 displays a message "Caution! You cannot post at this location" on the display unit 131 to prohibit posting.

If "NO" is determined in step S4, the posting position setting unit 111 sets the posting position based on the reference position (step S9). As shown in FIG. 12, when any of the objects R2 displayed on the map M is selected by the user, the posting position setting unit 111 sets the reference position corresponding to the selected object R2 as the posting position. .. Then, the posting unit 114 transmits the posting information associated with the set posting position to the posting information server 20 using the communication unit 12 (step S8).
The above is a description of the process executed by the terminal device 10 at the time of posting.

<C-2: Operation when viewing user's posted information>
FIG. 13 is a flowchart showing a process executed by the terminal device 10 when the user's posted information is viewed.
First, in the terminal device 10, the position specifying unit 116 specifies the acquisition area (step S11). The position specifying unit 116 identifies the acquisition area based on the information input by the user using the input unit 132. Here, as shown in FIG. 14, it is assumed that the acquisition area W, which is a part of the area on the map M, is specified.
It is desirable that the position specifying unit 116 clearly indicates the acquisition area W on the map M. Further, although the acquisition area W is rectangular, it may have another shape.

Next, the acquisition unit 117 acquires the post information from the post information server 20 according to the acquisition area (step S12). FIG. 15 is a diagram for explaining the posted information acquired by the acquisition unit 117. Here, the acquisition unit 117 acquires a predetermined number of post information in the order in which the posting time is closer to the reference time among the post information associated with the post position belonging to the acquisition area W. The reference time is the time when the acquisition area W is specified here. The number of acquired posted information is, for example, "100", but it may be other than "100". As shown in FIG. 15, here, the acquisition unit 117 is used for 100 cases along the direction opposite to the traveling direction on the time axis (that is, the direction going back to the past) (an example of one direction on the time axis). Get post information. As a result, the posting information to which the posting position belongs in the acquisition area W and included in the period from "t0" to "t1" whose posting time is the reference time is acquired.

It will be described back to FIG.
Next, the display control unit 118 causes the display unit 131 to display the list screen of the posted information acquired by the acquisition unit 117 (step S13).

FIG. 16 is a diagram showing an example of a list screen of posted information. Here, the objects R1 and R2 are displayed according to the posting information included in the posting time from "t0" to "t1". The object R1 corresponds to the posting information for which the posting position is set using each mesh area. The object R2 corresponds to the posting information for which the posting position is set using the reference position. As shown in FIG. 16, only the object corresponding to the posting information of the posting position belonging to the acquisition area W is displayed, and the object corresponding to the posting information of the posting position belonging to the outside of the acquisition area W is not displayed.
In this way, among the posted information whose posting position belongs to the acquisition area W, only the posted information for 100 posts that dates back from the reference time to the past is displayed. Therefore, it is unlikely that the visibility of the posted information list screen will be reduced. Further, since the posting position is represented by using the mesh area or the reference position as described above, the detailed posting position such as latitude and longitude is not known to a third party.

Further, the display control unit 118 uses the display unit 131 to display the posted information on the timeline (step S14). When the acquisition area W is selected, the display control unit 118 causes the display unit 131 to display the posted information corresponding to the acquisition area W. FIG. 17 is a diagram showing an example of timeline display of posted information. When the posting information is displayed on the timeline by designating the acquisition area W, for example, it is as shown in FIG. In this example, 100 post information is displayed in chronological order at the time of posting so that the closer the time of posting is to the reference time, the higher the ranking. When the user selects any of the posted information of the display control unit 118, it may be specified which of the objects R1 and R2 described in FIG. 16 corresponds to.
When the object R1 or R2 is selected, the display control unit 118 causes the display unit 131 to display the posting information corresponding to this object.

It will be described back to FIG.
When the user wants to browse the posted information retroactively at the time of posting in the past, the user inputs the information related to the update request of the posted information by using the input unit 132. Here, it is assumed that the operation of selecting the soft button B11 shown in FIG. 16 is performed. When the acquisition unit 117 receives the input of the posting information update request (step S15), the acquisition unit 117 acquires the posting information from the posting information DB 210 (step S16). Here, as the acquisition area, the acquisition area W specified in step S11 is used as it is. The acquisition unit 117 acquires a predetermined number of post information in order from the post information whose posting position belongs to the acquisition area W at the time of posting, which is closest to the time of posting of the post information last acquired in step S12. .. That is, the acquisition unit 117 acquires additional 100 posting information along the direction opposite to the traveling direction on the time axis (that is, the direction in which the posting time goes back to the past). As a result, the posting information to which the posting position belongs in the acquisition area W and the posting position is included in the period from "t1" to "t2" is acquired.

It will be described back to FIG.
Next, the display control unit 118 causes the display unit 131 to display the posted information list screen (step S17). FIG. 18 is a diagram showing an example of a list screen of posted information. This list screen has the same configuration as the list screen described with reference to FIG. 16 except that the object corresponding to the posted information included in "t1" to "t2" at the time of posting is displayed.
The display control unit 118 may add the object corresponding to the newly acquired post information to the object corresponding to the previously acquired post information and display the object. Here, the display control unit 118 adds the posting information to the objects corresponding to the posting information included from "t0" to "t1" at the time of posting, and the posting information included from "t1" to "t2" at the time of posting. The object corresponding to may be displayed. In this case as well, the number of posted information added at one time is still limited to a fixed number.

Further, the display control unit 118 uses the display unit 131 to display the posted information on the timeline (step S18). When the acquisition area W is selected, the display control unit 118 causes the display unit 131 to display the posted information corresponding to the acquisition area W. FIG. 19 is a diagram showing an example of timeline display of posted information. This timeline display has the same configuration as the timeline display described with reference to FIG. 17, except that the object corresponding to the posted information included from "t1" to "t2" at the time of posting is displayed.
The display control unit 118 may add the newly acquired post information to the previously acquired post information to display the timeline. Here, the display control unit 118 adds the posted information included from "t0" to "t1" at the time of posting, and displays the posted information included from "t1" to "t2" at the time of posting. In this case as well, the number of posted information added at one time is still limited to a fixed number. Further, when the object R1 or R2 is selected, the display control unit 118 causes the display unit 131 to display the posting information corresponding to this object.

Every time the user inputs the information related to the update request of the posted information, the processing steps of steps S15 to S18 are executed, and the posted information is updated one after another. Here, since the posted information is updated in units of 100, the complexity of the list screen and the timeline display is suppressed.

The acquisition unit 117 not only sequentially acquires 100 posted information along the direction opposite to the traveling direction on the time axis (that is, the direction going back to the past), but also, as shown in FIG. 20, the time axis. A fixed number of posting information may be acquired along the above traveling direction (that is, the direction in which the posting time advances). Here, when the operation of selecting the soft button B12 shown in FIG. 17 or FIG. 19 is performed, the acquisition unit 117 performs the reference time from “t0” to “t3” and from “t3” to “t4”. In that order, get the posted information.
The soft buttons B11 and B12 may be replaced with other display components such as slider-type buttons.

According to the posting information system 1 of the embodiment described above, the terminal device 10 does not download a large amount of posting information even in a place where a large amount of posting information exists. In addition, the user is less likely to have to search for the post information he / she desires from the large amount of post information because a large amount of newly added post information is newly added and displayed at one time. Therefore, according to the posting information system 1, it is possible to make it easier for the user to browse the posted information desired by the user from the posted information associated with the posting position.

[Modification example]
The present invention can be implemented in a form different from the above-described embodiment. The present invention can also be implemented, for example, in the following forms. In addition, the following modifications may be combined as appropriate.
(Modification example 1)
In the above-described embodiment, the area is set for each mesh area when the posting position is ambiguous, but the present invention is not limited to this. For example, an area may be set for each area having a predetermined shape / size such as a circle, or an area having an arbitrary shape / size may be set by the user. Again, the larger the area, the more ambiguous the posting position. Even when the restricted area is set, the area does not have to be set for each mesh area.

(Modification 2)
The posting position setting unit 111 may change the degree of ambiguity of the posting position without specifying by the user.
(I) Content of posted information The posted position setting unit 111 may change the degree of ambiguity of the posted position according to the content of the posted information. For example, when the posted information includes information related to personal privacy such as name, age, gender, work place, etc., the posting position setting unit 111 increases the degree of ambiguity of the posting position. On the contrary, when such information is not included, the posting position setting unit 111 reduces the degree of ambiguity of the posting position. The relationship between the content of the posted information and the degree of ambiguity of the posted position may be determined in advance.

(Ii) Distance from a predetermined position The posting position setting unit 111 may change the degree of ambiguity of the posting position according to the distance from the predetermined position. For example, in the vicinity of the user's home or work place, the precise posting position is not desired to be grasped by a third party, but at a travel destination, etc., there may be no problem even if the precise posting position is grasped by a third party. Is.

(Iii) The time posting position setting unit 111 may change the degree of ambiguity of the posting position according to the time. For example, in the morning and afternoon postings, we do not want a third party to know the precise posting position in the sense that it is easy to grasp daily activities, but at night, the precise posting position is grasped by a third party. However, there may be no problem.

(Iv) Location The posting position setting unit 111 may change the degree of ambiguity of the posting position according to the position of the user (the position of the terminal device 10). For example, in a place where the user's position at the time of posting is an urban area, there are many places such as tourist spots and landmarks, so the precise posting position may be grasped by a third party, but a place such as a depopulated area. This is because it may be easy for a third party to grasp the precise posting position.

(V) Others In addition, when the posting information is disclosed only to the followers, the posting position setting unit 111 may change the degree of ambiguity of the posting position according to the attributes (friends, etc.) of the other party to be disclosed. Good.

(Modification example 3)
The restricted position setting unit 115 may set the restricted area without the user of the own terminal device 10 designating the restricted area.
(I) The user's movement route restriction position setting unit 115 may set the restriction area according to the user's movement route. This is because the user's movement route is one that the user passes through on a daily basis, so that it is easy for a third party to grasp the daily behavior. The movement route may be specified by the user or may be automatically set based on the positioning result of the positioning unit 14.

(Ii) The restricted position setting unit 115 of the user's action base may set the restricted area according to the user's action base. Bases include homes and offices. This is because the base of the user's behavior is the place where the user is on a daily basis, so that a third party can easily grasp the daily behavior.

(Iii) The restricted position setting unit 115 for the action base of another person may set the restricted area according to the action base of another person who is not a user of the own terminal device 10. Others are, for example, friends, followers on SNS, and the like. Bases include homes and offices. As a result, it is possible to prevent the user from being inconvenienced by improper posting by another person.

(Iv) Restricted Area Set by Others The restricted position setting unit 115 may set the restricted area set by another person as the restricted area in the own terminal device 10. In other words, the restricted position setting unit 115 may set the restricted area set in the terminal device 10 of another person as the restricted area in the own terminal device 10. As a result, for example, it becomes easy to prevent an inappropriate posting by another person who does not mind in the vicinity of a base such as the home of the user of the terminal device 10. In this case, the condition of "another person" is not particularly limited. For example, it may be all other people other than the user of the own terminal device 10, or may be another person who has a predetermined relationship with the user of the own terminal device 10, such as a friend or a follower in SNS.

FIG. 21 is a diagram for explaining the posted information acquired by the acquisition unit 117 of this modified example. Similar to the above-described embodiment, when the operation of selecting the soft button B11 is performed, the acquisition unit 117 acquires a predetermined number of posting information (here, 100) in the order of close posting time at the reference time. get. On the other hand, when the operation of selecting the soft button B12 is performed, the acquisition unit 117 acquires a predetermined number of posting information in the order in which the posting time is closest to the present. Here, when the posted information from "t5" to the present time is acquired in response to the operation of the soft button B12, the posted information is still acquired by the acquisition unit 117 during the period from "t0" to "t6". It exists as an "unacquired period" that has not been acquired. Therefore, the display control unit 118 may display the soft button B13 for acquiring the posted information in the unacquired period on the map M. When the soft button B13 is operated, the acquisition unit 117 acquires a predetermined number of posting information during the non-acquisition period. Specifically, the acquisition unit 117 acquires a predetermined number of posted information in the order of newest posting time among the posted information belonging to the non-acquisition period at the time of posting. Here, the acquisition unit 117 acquires the posting information whose posting time belongs to "t5" to "t6". Next, when the soft button B13 is operated, the acquisition unit 117 acquires the posting information whose posting time belongs to "t0" to "t5". If there is no unacquired period, the display control unit 118 does not display the soft button B13.

(Modification 5)
The acquisition unit 117 may change the number of acquisitions of posted information according to the size of the acquisition area. The larger the size of the acquisition area, the more post information to which the post position in the acquisition area belongs. Therefore, the acquisition unit 117 may increase the number of posted information to be acquired as the size of the acquisition area is larger.

(Modification 6)
