Further, some devices may be replaced with other devices having similar functions. Further, the functions of the present embodiment may be distributed and realized in a plurality of devices.

Subsequently, the operation of the information sharing system 1 configured as described above will be described with reference to FIGS. 4 to 9.

FIG. 4 is a sequence diagram showing an example of the processing of the information sharing system 1 in the present embodiment. This process is executed when the command terminal 10 is running the map application. In the following, a case where the map image is not yet displayed in the initial state immediately after the start of the map application will be described as an example.

First, the command terminal 10 determines whether or not the execution of the search process is requested on the command screen of the map application being displayed (step S101). Here, when the command terminal 10 determines that the execution of the search process is requested (step S101: YES), the process proceeds to step S102. On the other hand, when the command terminal 10 determines that the execution of the search process is not requested (step S101: NO), the process of step S101 is repeated.

FIG. 5 is a diagram showing an example of a command screen displayed on the command terminal 10 in the present embodiment. Here, on the left side of the screen, a plurality of input fields A1, A2, A3, a search button A4, and a search result display field A5 in the command terminal 10 are provided. Further, the map image IMG_1 is displayed on the right side of the screen.

The input field A1 is an area for the user to input an arbitrary search word. The input field A2 is an area for the user to input an address. In the input field A3, either "not specified" or "in the map" can be selected as the search range. When "in the map" is selected in the input field A3, the place name, road name, building name, station name, etc. included in the map information held by the map application are searched. When "not specified" is selected in the input field A3, various data held by the command terminal 10 are searched in addition to the map information. Then, when the user presses the search button A4 after the search word is input in the input field A1 or the like, the search process is executed on the command terminal 10. Further, when "not specified" is selected in the input field A3, when the cooperation display mode is selected, the search process to the portal site 40 in the information sharing terminal 20 of the cooperation destination is performed to the map information providing system 30. It is executed in parallel with the search process. Details will be described later.

The map image IMG_1 is sequentially updated when the point information is selected from the search results in the display field A5, or when the address is input in the address input field. The pointer P1 provided in the center of the map image IMG_1 indicates the coordinates of the designated point. The pointer P1 can be changed arbitrarily.

Further, under the map image IMG_1, three types of buttons B1, B2, and B3 for designating the linked display mode in the information sharing terminal 20 are provided. The "map display mode" is a mode in which the map information providing system 30 is accessed from the command terminal 10 based on the designated position information, and the acquired normal map is displayed on the screen.

The "street view display mode" is a mode for displaying a street view image acquired from the map information providing system 30 on the screen based on the same position information. The "aerial photograph display mode" is a mode in which an image of an aerial photograph acquired from the map information providing system 30 based on the same position information is displayed on the screen. In the case of "Street view display mode" or "Aerial photograph display mode", the convenience is improved if the display of the normal map image is omitted. If there are other types of maps (for example, topographic maps, route maps, etc.) provided by the map information providing system 30, the number of linked display modes may be further increased.

In step S102, the command terminal 10 executes a search process based on the information of the search word and the search range input by the user operation, and displays the search result in the command screen.

In step S103, the command terminal 10 displays a map image centered on a point designated from the search results by the user operation in the command screen.

Next, the command terminal 10 determines whether or not the coordinates are specified in the map image by the user operation (step S104). Here, when the command terminal 10 determines that the coordinates are specified in the map image (step S104: YES), the process proceeds to step S105. On the other hand, when the command terminal 10 determines that the coordinates are not specified in the map image (step S104: NO), the process of step S104 is repeated.

In step S105, the command terminal 10 creates a two-dimensional bar code representing position information corresponding to the designated coordinates on the screen. In addition to the position information (latitude and longitude), the two-dimensional bar code can include the scale of the map displayed on the information sharing terminal 20, the search word input by the user on the command screen, and the like.

Next, the command terminal 10 outputs the video data of the two-dimensional bar code including the position information to the information sharing terminal 20 via the video cable C1 (step S106). The two-dimensional bar code is, for example, a QR code (registered trademark).

When the information sharing terminal 20 acquires the video data of the two-dimensional code output from the command terminal 10 by the video capture unit 211, the information sharing terminal 20 stores the video data in a storage area such as the RAM 202 (step S107).

In step S108, the command terminal 10 determines whether or not the linked display mode is specified on the command screen by the user operation. Specifically, it is determined whether or not the button for causing the information sharing terminal 20 to execute the linked display process is pressed.

When the command terminal 10 determines that the linked display mode is specified on the screen (step S108: YES), the command terminal 10 outputs a contact signal indicating the linked display mode to the information sharing terminal 20 (step S109). After that, the process proceeds to step S110. On the other hand, when the command terminal 10 determines that the cooperation display mode is not specified (step S108: NO), the process returns to step S104.

In step S110, when the information sharing terminal 20 reads the video data of the two-dimensional bar code stored in the RAM 202 or the like with the input of the contact signal as a trigger, the information sharing terminal 20 is included in the two-dimensional bar code by analyzing the video data. Acquire location information, etc.

Next, the information sharing terminal 20 specifies the linked display mode from the contact signal input from the command terminal 10 (step S111). At this time, the information sharing terminal 20 shall specify the search type indicating the information to be searched based on the linked display mode. In the example of FIG. 5, any one of "map display mode", "street view display mode", and "aerial photograph display mode" is specified.

Next, the information sharing terminal 20 activates the WEB browser, accesses the map information providing system 30 on the wide area network NW based on the position information indicated by the two-dimensional bar code, and executes the search process (step S112). ..

Then, the information sharing terminal 20 displays the map image obtained from the map information providing system 30 by the search process on the screen based on the linked display mode specified in step S111 (step S113). When the designated coordinates are changed in the command terminal 10, the processes of steps S101 to S113 described above are repeatedly executed. That is, the map screen on the command terminal 10 and the map screen displayed on the information sharing terminal 20 are updated in conjunction with each other. Similarly, when the map screen ends in the command terminal 10, the map screen also closes in the information sharing terminal 20.

6 to 9 are diagrams showing an example of a screen linked and displayed on the information sharing terminal 20 according to the present embodiment. FIG. 6 shows a screen when the linked display mode is the map display mode. Here, the map image IMG_2 in the default format acquired from the map information providing system 30 is displayed on the screen. The latitude and longitude of the pointer P2 provided in the center of the map image IMG_2 match the latitude and longitude values corresponding to the coordinates of the pointer P1 designated on the map of the command screen of the command terminal 10. That is, although the acquisition destination of the map information is different between the command terminal 10 and the information sharing terminal 20, each terminal displays a map centered on the same point. The scale of the map image IMG_1 may be the same as the scale of the map image IMG_1 in the command terminal 10.

FIG. 7 shows a screen when the linked display mode is the street view display mode. Here, instead of a normal map, a street view image (appearance image) IMG_3 at a designated point is displayed. That is, the command terminal 10 can skip the normal map display on the information sharing terminal 20 and display the street view image IMG_3. The user of the information sharing terminal 20 can grasp the appearance of the building at the designated point and the surroundings of the building by referring to the street view image IMG_3.

FIG. 8 shows a screen when the linked display mode is the aerial photograph display mode. Here, instead of a normal map, an aerial photograph image IMG_4 centered on a designated point is displayed. Similar to the case of FIG. 7, the command terminal 10 can skip the normal map display on the information sharing terminal 20 and display the aerial photograph image IMG_4. The latitude and longitude corresponding to the coordinates of the pointer P3 provided in the center of the aerial photograph image IMG_4 are the latitude and longitude values corresponding to the coordinates of the pointer P1 specified on the map of the command screen of the command terminal 10. Match.

FIG. 9 shows a case where the WEB browser of the information sharing terminal 20 separately displays a tab T2 for displaying search results for the portal site 40 in addition to the tab T1 for displaying map information. As described with reference to FIG. 5, the command terminal 10 can be searched by a user operation using a search word (place name / building name, etc.) in the map. The command terminal 10 generates a two-dimensional bar code indicating the information input for the search and the search destination system in the information sharing terminal 20. As a result, the information sharing terminal 20 can access the map information providing system 30 and acquire map information based on the received two-dimensional bar code (tab T1). Further, the information sharing terminal 20 can also perform a normal browser search for the portal site 40 based on the search word indicated by the two-dimensional bar code received from the command terminal 10 (tab T2). For example, when "not specified" is selected in the input field of the search range shown in FIG. 5, the information sharing terminal 20 may execute the search process for the portal site 40. However, the method of instructing the search destination in the information sharing terminal 20 in the command terminal 10 is not limited to this. As the search destination, one or both of the map information providing system 30 and the portal site 40 can be specified.

As described above, the information sharing system 1 in the present embodiment connects between the command terminal 10 and the information sharing terminal 20 by using a communication cable (video cable C1 and contact signal cable C2) capable of communicating in one direction. Therefore, the command terminal 10 cannot be accessed from the information sharing terminal 20 side. Therefore, information necessary for searching can be shared between the command terminal 10 and the information sharing terminal 20 without deteriorating the confidentiality of the command terminal 10 connected to the closed network.

It is different from the form. It is assumed that the command output by the command terminal 10 of the present embodiment to the information sharing terminal 20 is included in the video data of the two-dimensional bar code.

FIG. 11 is a sequence diagram showing an example of the processing of the information sharing system 2 in the present embodiment. This process is executed when the command terminal 10 is running the map application. In the following, a case where the map image is not yet displayed in the initial state immediately after the start of the map application will be described as an example.

First, the command terminal 10 determines whether or not the execution of the search process is requested on the command screen of the map application being displayed (step S201). Here, when the command terminal 10 determines that the execution of the search process is requested (step S201: YES), the process proceeds to step S202. On the other hand, when the command terminal 10 determines that the execution of the search process is not requested (step S201: NO), the process of step S201 is repeated.

In step S205, the command terminal 10 determines whether or not the linked display mode is specified on the command screen by the user operation. Specifically, it is determined whether or not the button for causing the information sharing terminal 20 to execute the linked display process is pressed (see FIG. 5).

When the command terminal 10 determines that the linked display mode is specified on the screen (step S205: YES), the process proceeds to step S206. On the other hand, when the command terminal 10 determines that the linked display mode is not specified (step S205: NO), the process returns to step S204.

In step S206, the command terminal 10 creates a two-dimensional bar code video data based on the position information corresponding to the coordinates designated on the screen and the designated linked display mode. The two-dimensional bar code can also include a scale of a map displayed on the information sharing terminal 20, a search word input by the user on the command screen, and the like.

When the command terminal 10 determines that the linked display mode is specified on the screen (step S305: YES), the process proceeds to step S306. On the other hand, when the command terminal 10 determines that the cooperation display mode is not specified (step S305: NO), the process returns to step S304.

In step S306, the command terminal 10 creates a two-dimensional bar code video data based on the position information corresponding to the coordinates designated on the screen and the designated linked display mode. The two-dimensional bar code can also include a scale of a map displayed on the information sharing terminal 20, a search word input by the user on the command screen, and the like.

Next, the command terminal 10 outputs the video data of the two-dimensional bar code including the position information and the linked display mode to the capture device 50 via the video cable C1 (step S307). The two-dimensional bar code is, for example, a QR code (registered trademark). Along with this, the capture device 50 displays the two-dimensional bar code on the display device 508 (step S308).

FIG. 15 is a diagram showing an example of a two-dimensional bar code displayed on the capture device 50 (display device 508) in the present embodiment. In the image IMG_5 of this two-dimensional bar code, in addition to the position information (latitude and longitude) and the selection instruction information of the cooperation display mode, the scale of the map to be displayed on the information sharing terminal 20 and the search input by the user on the command screen. Words etc. are included. The capture device 50 may turn off the screen display or display another standby screen until the video data of the two-dimensional bar code is input.

The photographing device 60 photographs the screen of the capture device 50 at a predetermined cycle (step S309), and outputs the captured image to the information sharing terminal 20 (step S310). That is, the photographing device 60 constantly monitors the screen of the capture device 50.

Next, when the information sharing terminal 20 acquires the photographed image data output from the photographing device 60 by the video capture unit 211, the information sharing terminal 20 analyzes the photographed image data to display the position information included in the two-dimensional bar code and the cooperative display mode. Both are acquired (step S311).

Next, the information sharing terminal 20 activates the WEB browser, accesses the map information providing system 30 on the wide area network NW based on the position information indicated by the two-dimensional bar code, and executes the search process (step S312). ..

Then, the information sharing terminal 20 cooperates and displays the map image obtained by the search process on the screen based on the cooperation display mode acquired in step S311 (step S313). When the designated coordinates are changed in the command terminal 10, the processes of steps S301 to S313 described above are repeatedly executed.

As described above, according to the information sharing system 3 in the present embodiment, the command terminal 10 and the information sharing terminal 20 are completely separated. That is, as in the first embodiment, the command terminal 10 cannot be accessed from the information sharing terminal 20 side. Therefore, information necessary for searching can be shared between the command terminal 10 and the information sharing terminal 20 without deteriorating the confidentiality of the command terminal 10 connected to the closed network.

Further, since the command terminal 10 and the information sharing terminal 20 are completely separated, a portable terminal device such as a smartphone or a tablet terminal equipped with a digital camera can be used as the information sharing terminal 20.
