Subsequently, a registration processing program executed by the CPU 51 of the communication terminal 5 included in the information providing system 1 having the above configuration and a route guidance processing program executed by the CPU 41 of the navigation device 3 will be described with reference to FIG. FIG. 4 is a flowchart of the registration processing program and the route guidance processing program according to the present embodiment. First, the registration processing program shown in FIG. 4 will be described, and the route guidance processing program will be described later. Here, the registration processing program is executed, for example, by starting a predetermined application program after the system of the communication terminal 5 is started. The registration processing program is a program that receives input information of the user 4, displays a destination candidate site, and then transmits a public permission candidate site selected from the destination candidate sites to the navigation device 3. The registration processing program shown in the flowchart in FIG. 4 below is stored in, for example, a memory 52 included in the communication terminal 5 and executed by the CPU 51.

First, in S1 shown in FIG. 4, the CPU 51 of the communication terminal 5 connects with the navigation device 3 by communication of the communication standard of Bluetooth (registered trademark), and performs initial settings and the like necessary for processing the registration processing program. For example, the user 4 operates the communication terminal 5 to turn on the Bluetooth (registered trademark) function before starting the application program of the registration processing program. The user 4 operates the navigation device 3 to check the PIN code and the like, and operates the communication terminal 5 to input the PIN code and the like to perform pairing of the navigation device 3. When the application program of the registration processing program is executed with the pairing completed, the CPU 51 performs initial settings and the like with the navigation device 3 in S1. For example, the CPU 51 transmits information on the logged-in user of the application program, that is, information on the user 4 who is currently operating the communication terminal 5, and the like to the navigation device 3.

The CPU 51 executes S2 after executing S1. In S2, the CPU 51 acquires screen information from the navigation device 3 and executes a process of displaying the screen information on the display 59. FIG. 5 shows an example of a display screen displayed on the display 59 of the communication terminal 5. As shown in FIG. 5, the CPU 51 displays, for example, a map display field 71, a setting screen field 72, and an operation button field 73 in order from the top of the display 59.

The map display field 71 is, for example, a display field for displaying the same contents as the liquid crystal display 15 of the navigation device 3. In S2, the CPU 51 acquires the screen information displayed on the liquid crystal display 15 from the navigation device 3 and displays it in the map display field 71. In the map display field 71, for example, an image in which the current position mark 76 indicating the current position of the vehicle 2 is superimposed on the map image 75 around the vehicle 2 is displayed.

Further, the setting screen field 72 is a display field for displaying a search result of a candidate destination, an input field for a comment described later, and the like. In S2, the CPU 51 displays the search keyword input field 81 and the search button 82 shown in FIG. 5 in the setting screen field 72. Note that FIG. 5 shows a state in which the search results described later are displayed.

Further, the operation button column 73 is a display column for displaying operation buttons that accept various operations. In S2, the CPU 51 displays the back button 91, the comment addition button 92, the post button 93, the favorite registration button 94, and the list display button 95 in the operation button column 73. The back button 91 is a button for returning the display of the display 59. When the CPU 51 detects the touch operation of the back button 91, the CPU 51 returns the display of the display 59 to the previous screen. The operation contents of each button other than the back button 91 will be described later. Further, the CPU 51 may switch the display / non-display of the operation button column 73 according to a scroll operation (for example, a flick operation, a swipe operation, etc.) without always displaying the operation button column 73.

The CPU 51 executes S3 after executing S2 in FIG. The CPU 51 determines in S3 whether or not the search button 82 in the setting screen field 72 has been pressed. For example, as shown in FIG. 5, the user 4 inputs a keyword to be searched for in the search keyword input field 81, and then touches the search button 82. When the CPU 51 determines in S3 that the search button 82 has been pressed (S3: YES), the CPU 51 executes S4. In S4, the CPU 51 displays POI (Point of Interest) information 83 regarding the candidate destination of the search result in the setting screen column 72 (see FIG. 5).

The method for searching the POI information 83 of the candidate destination is not particularly limited, but the CPU 51 makes an inquiry to an external server via the communication network 6 based on the keyword entered in the search keyword input field 81, for example. It can be executed and the POI information 83 can be searched. The external server may be, for example, a search server prepared by the vendor of the application program or the navigation device 3, or a Web server of a general search site such as Google (registered trademark) or Yahoo (registered trademark). The CPU 51 executes the display of the POI information 83 based on the information of the search result acquired from the external server. The details of the display items of the POI information 83 will be described later with reference to FIG. Further, the CPU 51 searches for information necessary for route search of the destination candidate site, for example, the address of the destination candidate site, the telephone number, and the like, in addition to the search for the POI information 83. Then, as will be described later, the CPU 51 transmits information necessary for route search to the navigation device 3 (S8).

In the example shown in FIG. 5, a keyword for searching a restaurant as a candidate destination such as "delicious restaurant" is input. In this case, the CPU 51 transmits the information of the keyword of "delicious restaurant" to the external server and acquires the search result. In the setting screen field 72, restaurant information and the like corresponding to the keyword of "delicious restaurant" are displayed. The CPU 51 may accept a setting of whether or not to search for a destination candidate site (POI information 83) around the current position in the setting screen column 72 or the like. Then, when the setting is accepted, the CPU 51 may send information on the current position of the communication terminal 5 and the current position of the navigation device 3 to the external server together with the keyword to search for restaurants and the like around the current position. .. As a result, the search result according to the current position can be acquired from the external server. Alternatively, the CPU 51 may display the POI information 83 acquired from the external server in the order of proximity to the current position.

The CPU 51 executes S5 after executing S4. Further, when the CPU 51 makes a negative determination in S3 (S3: NO), the CPU 51 executes S5. In S5, the CPU 51 executes the process of accepting comments, accepting favorite registrations, and setting the POI information 83 to be public / private, that is, the setting of public / private setting of the destination candidate site. For example, when any one of the plurality of POI information 83 displayed in the setting screen field 72 of FIG. 5 is touch-operated, the CPU 51 displays the screen shown in FIG. 6 on the display 59. The CPU 51 enlarges and displays the touch-operated POI information 83 in the setting screen field 72.

As shown in FIG. 6, the CPU 51 displays, for example, a store name, a photo of the store, business hours, regular holidays, and store information as the POI information 83. As the store information, use information that user 4 may be interested in the facilities of the candidate destination, such as information on all-you-can-eat pizza and information on holding a fair for a limited time. Can be done. The POI information 83 shown in FIG. 6 is an example. For example, the CPU 51 may display the address, telephone number, or the like of the candidate destination as the POI information 83. Further, when the CPU 51 detects a touch operation of the return button 91 in the operation button column 73 while displaying the screen shown in FIG. 6, the CPU 51 displays the screen shown in FIG.

When the CPU 51 detects the touch operation of the comment addition button 92 in the state of displaying the screen shown in FIG. 6, the screen shown in FIG. 7 is displayed on the display 59. As shown in FIG. 7, the CPU 51 displays a comment input field 77 below the setting screen field 72. The CPU 51 displays the comment input box 101, the OK button 102, and the cancel button 103 in the comment input field 77. When the CPU 51 detects a touch operation of the OK button 102 while characters or the like are input to the comment input box 101, the CPU 51 adds the comment input to the comment input box 101 to the setting screen field 72 as shown in FIG. (S5). As a result, a comment can be added to the destination candidate site (POI information 83) selected from the search results. The user 4 can input a comment for the desired POI information 83 by inputting characters such as "here is recommended" in the comment input box 101. Further, when the CPU 51 detects the touch operation of the cancel button 103 in the state of displaying the screen shown in FIG. 7, the screen shown in FIG. 6 is displayed on the display 59.

Further, when the CPU 51 detects a touch operation of the registration button 94 in the operation button field 73 while displaying the screens shown in FIGS. 6 and 8, the POI information 83 selected and displayed in the setting screen field 72, that is, the POI information 83, that is, Register the candidate destination as a favorite (S5). The CPU 51 stores POI information 83 and comments registered as favorites in, for example, the memory 52 of the communication terminal 5. As a result, the user 4 visits the candidate destination (POI information 83) that he / she wants to visit, the user 4 who is different from the passenger this time, and the candidate destination (POI information) that he / she visited in the past and left comments such as his / her impressions of cooking. 83) and the like can be stored in the communication terminal 5 as favorite registrations.

When the CPU 51 detects the touch operation of the list display button 95 in the operation button column 73, the CPU 51 displays the screen shown in FIG. 9 on the display 59. As shown in FIG. 9, the CPU 51 displays the POI information 83 registered as favorites and the comments added to the POI information 83 as a list in the setting screen column 72. As a result, the user 4 can select a destination candidate destination to be visited from the POI information 83 registered as a favorite. When the CPU 51 detects a touch operation of arbitrary POI information 83 while displaying the screen of FIG. 9, the CPU 51 displays the selected POI information 83 and accepts comments and the like as shown in FIG. Is also good.

Further, as shown in FIGS. 6 to 8, the CPU 51 displays the private setting box 85 that accepts the public / private setting of the destination candidate site in the setting screen column 72. Here, as described above, the application program of the present embodiment can add a comment to the POI information 83 of the candidate destination and register it as a favorite. For example, the user 4A may use the application program not only when moving to the destination together with the users 4B to 4C shown in FIG. 1 but also when moving with another user 4. In this case, the user 4A may want to keep the user 4 other than the users 4B to 4C and the restaurants and the like visited in the past secret from the users 4B to 4C. That is, in the destination candidate sites registered as favorites of any user 4, a public permission candidate site that may be disclosed to other users 4 on board and a destination candidate site that is desired to be kept private (hereinafter, (Called a private candidate site) may be included. Therefore, in the application program of the present embodiment, it is possible to prohibit disclosure to another user 4 by setting private setting in the private setting box 85.

More specifically, the CPU 51 executes S6 after executing the process of S5. In S6, the CPU 51 determines whether or not the post button 93 of the operation button column 73 has been pressed. For example, when the CPU 51 detects the touch operation of the post button 93 in the state of displaying the screen shown in FIG. 6, it makes a positive judgment in S6 (S6: YES) and executes S7. In this case, the CPU 51 sets the destination candidate site of the POI information 83 displayed in the setting screen field 72 as the target destination candidate site to be transmitted to the navigation device 3.

In S7, the CPU 51 determines whether or not the destination candidate site to be transmitted is a public permission candidate site. As shown in FIG. 6, a private setting box 85 is displayed in the setting screen field 72. By checking the private setting box 85, the user 4 can set the destination candidate site of the POI information 83 displayed in the setting screen field 72 as the private candidate site. When the CPU 51 detects the touch operation of the post button 93 in the state where the check is not entered in the private setting box 85, that is, when the transmission operation of the public permission candidate site is executed, the CPU 51 makes an affirmative judgment in S7 (S7: YES), execute S8. In S8, the CPU 51 transmits the information related to the public permission candidate site to be transmitted to the navigation device 3. The information related to the public permission candidate site referred to here is the POI information 83 (selected by the user 4) displayed in the setting screen field 72 of FIG. 6, the information of the comment added to the POI information 83, and the information to be transmitted. Information of the user 4, information (address, telephone number, etc.) necessary for route search of the candidate site for disclosure permission. As will be described later, the navigation device 3 executes a route search for the received public permission candidate site. Therefore, the CPU 51 transmits the information necessary for the route search of the public permission candidate site in S8. Further, the information of the user 4 to be transmitted is, for example, the information of the user 4 who has started the registration processing program of FIG. 4 and executed login authentication or the like. As will be described later, the navigation device 3 changes the display mode of the public permission candidate site for each user 4. Therefore, in S8, the CPU 51 transmits information that identifies the user 4 who has transmitted the public permission candidate site.

On the other hand, when the CPU 51 detects the touch operation of the post button 93 with the check entered in the private setting box 85, that is, when the transmission operation of the private candidate site is executed, it determines negatively in S7 (S7). : NO), S9 is executed. In S9, the CPU 51 displays an error or the like. For example, the CPU 51 displays a warning on the display 59 that it is about to post a private candidate site and a screen that accepts whether the private candidate site may be posted (S9). The warning notification method is not limited to the method of displaying an error screen, and may be a method of emitting a warning sound from the speaker 57.

Further, the CPU 51 executes S10 after executing S8, after executing S9, or after making a negative determination in S6 (S6: NO). In S10, the CPU 51 determines whether or not the end of the application program has been accepted. For example, when the CPU 51 accepts a touch operation for terminating the application program, a flick operation, or the like in a predetermined display state, the CPU 51 makes an affirmative determination in S10 (S10: YES) and terminates the registration processing program shown in FIG.

On the other hand, when the CPU 51 makes a negative determination in S10 (S10: NO), the CPU 51 re-executes the process from S2. As a result, the CPU 41 acquires the latest map image 75 and the like from the navigation device 3 in S2, and periodically updates the contents of the map display field 71. In addition, the user 4 can appropriately search for a candidate destination, add a comment, send a candidate site for permission to publish, set public / private, and register a favorite. The processing contents, order, and the like of the flowchart shown in FIG. 4 are examples and can be changed as appropriate. For example, a program for searching a candidate destination, a program for adding a comment, and a program for accepting public / private may be separate programs.

Further, the CPU 51 may execute transmission of a plurality of public permission candidate sites at one time. For example, when the CPU 51 touches the registration button 94 after entering a check in the private setting box 85 while displaying the screens shown in FIGS. 6 and 8, the selected destination candidate destination is selected. Register as a favorite as a private candidate site. Further, as shown in FIG. 9, the CPU 51 displays public / private information on the left side of the registered POI information 83. Then, the CPU 51 may display the check box 105 for the POI information 83 of the public permission candidate site. For example, when the CPU 51 detects a touch operation of the post button 93 while a check is input to the plurality of check boxes 105, the CPU 51 collectively transmits the information of the plurality of public permission candidate sites for which the check is input to the navigation device 3. To do. As a result, the user 4 can collectively transmit the public permission candidate sites among the destination candidate sites registered as favorites to the navigation device 3.

As shown in FIG. 9, the CPU 51 sets a selection box 107 in which the POI information 83 displayed on the favorite registration screen can be selected to be narrowed down to only the candidate sites for public permission or only the candidate sites for non-publication. It may be displayed in. As a result, the user 4 can easily check the public permission candidate sites and the private candidate sites at once, and can set public / private settings, add comments, and the like.

Subsequently, the route guidance processing program executed by the CPU 41 of the navigation device 3 will be described with reference to FIG. Here, the route guidance processing program is executed, for example, after the power of the navigation device 3 is turned on and the system is started. The route guidance processing program is a program that displays the POI information 83 and comments of the public permission candidate site received from the communication terminal 5 on the map, and executes the route guidance with the displayed public permission candidate site as the destination. The route guidance processing program shown in the flowchart in FIG. 4 below is stored in, for example, a RAM 42 or a ROM 43 included in the navigation device 3 and is executed by the CPU 41. Further, the condition for starting the execution of the registration processing program is not limited to the condition for turning on the power of the navigation device 3, and may be, for example, the condition for touching a specific button on the touch panel 14.

First, in S21 shown in FIG. 4, the CPU 41 of the navigation device 3 determines whether or not the information related to the public permission candidate site transmitted in S8 is received from the communication terminal 5. When the CPU 41 receives the information related to the public permission candidate site from the communication terminal 5 (S21: YES), the CPU 41 executes S22. In S22, the CPU 41 displays the public permission candidate site on the map of the liquid crystal display 15 based on the information related to the public permission candidate site received in S21. On the other hand, the communication terminal 5 acquires the updated screen information from the navigation device 3 by executing S2 after transmitting the public permission candidate site in S8, and displays the map information on which the public permission candidate site is displayed 59. Display on.

FIG. 10 shows a state in which the public permission candidate site 111 is displayed in the map display field 71. FIG. 11 shows a state in which the public permission candidate site 111 is displayed on the liquid crystal display 15. As described above, the display content of the liquid crystal display 15 of the navigation device 3 and the display content of the map display field 71 of the communication terminal 5 are synchronized and have the same content. However, in order to avoid cluttering the drawings and make the explanation easier to understand, the map display field 71 of FIG. 10 shows simplified contents and is different from the display contents of FIG. Further, in the map display field 71 of FIG. 10, one candidate site for permission to publish 111 is displayed as an example. Further, as an example, the liquid crystal display 15 of FIG. 11 displays eight public permission candidate sites 111, 122, 123, 124, 125, 126, 127, 128. In the following description, when the public permission candidate sites 121 to 128 are collectively referred to, they will be referred to as public permission candidate sites 111.

As shown in FIGS. 10 and 11, the CPU 41 superimposes the map image 75 on the public permission candidate site 111. The CPU 41 displays the POI information 83, the comment 112, the user information 113, the evaluation button 114, the comment addition icon 115, and the history display icon 116 as the information of the public permission candidate site 111. The POI information 83 and the comment 112 are information received from the communication terminal 5 in S21. Therefore, the CPU 41 displays the comment 112 collected from each user 4 (poster user 4) in association with the public permission candidate site 111. The user information 113 is information of the user 4 who has transmitted the POI information 83 and the comment 112, and is a user name, a user ID, and the like. Therefore, the CPU 41 adds and displays the information of the user 4 who has set the comment 112 to the comment 112. The details of the evaluation button 114, the comment addition icon 115, and the history display icon 116 will be described later.

Here, the navigation device 3 of the present embodiment collects the public permission candidate sites 111 from the plurality of users 4 through the communication terminal 5. When displaying the public permission candidate site 111, the navigation device 3 color-codes each user 4 and changes the display mode of the public permission candidate site 111. FIG. 12 shows the color coding for each user 4 by a line type. As shown in FIGS. 11 and 12, for example, the CPU 41 adds colors such as red, blue, yellow, and green to the POI information 83 and the comment 112 of each of the users 4A to 4D. , It is displayed in different colors for each user 4. Then, in S22, the CPU 41 displays the information (POI information 83, etc.) of the public permission candidate site 111 in a light color. This is because, in S25 described later, only the public permission candidate site 111 set as the destination is displayed in a dark color, so that the difference from the light-colored public permission candidate site 111 not set as the destination is different from the user 4. This is to make it easier for people to recognize. The CPU 41 may color-code only the outer frame of the POI information 83 and the like, and may also color-code characters such as the store name.

Further, the CPU 41 automatically adjusts the scale of the map image 75 in S22. As shown in FIG. 11, the CPU 41 of the map image 75 so that the information (POI information 83, comment 112, etc.) related to the public permission candidate site 111 posted by each user 4 is displayed in the liquid crystal display 15. The scale is automatically adjusted. For example, when displaying a new public permission candidate site 111, the CPU 41 displays information related to all public permission candidate sites 111 including the new public permission candidate site 111 and the current position mark 76 of the vehicle 2. As described above, the map image 75 is reduced and adjusted. Alternatively, when the CPU 41 displays the new comment 112 by the comment addition icon 115 described later, the new comment 112, the information related to all the public permission candidate sites 111, and the current position mark 76 of the vehicle 2 are displayed. In addition, the map image 75 is reduced and adjusted. As a result, the information of all the public permission candidate sites 111 and the current position mark 76 can be displayed on one screen.

Further, the CPU 41 executes S23 after executing S22. Further, when the CPU 41 makes a negative determination without receiving the information related to the public permission candidate site 111 from the communication terminal 5 in S21 (S21: NO), the CPU 41 executes S23. In S23, the CPU 41 executes the display change process of the liquid crystal display 15.

As shown in the lower right of the liquid crystal display 15 of FIG. 11, the CPU 41 displays a scale change button 131 for changing the scale of the map image 75. Each time the CPU 41 detects a touch operation on the scale change button 131 in S23, the CPU 41 switches the display content between the display screen shown in FIG. 11 and the enlarged display screen around the current position shown in FIG. Further, as shown in FIGS. 11 and 13, by switching the display mode of the scale change button 131 of each screen display, it is possible to show the user 4 which scale state the current state is. Further, the touch operation on the scale change button 131 may be detected by the liquid crystal display 15 or may be detected by the display 59 of the communication terminal 5.

As shown in FIG. 13, the CPU 41 displays a map image 75 enlarged around the current position mark 76 on the liquid crystal display 15 based on the touch operation of the scale change button 131. The CPU 41 enlarges and displays the map image 75 in a predetermined range, for example, with reference to the current position of the vehicle 2. The predetermined range based on the current position of the vehicle 2 is, for example, a range in which the driving driver can confirm the driving road condition (the position of the next intersection, the position of the signal, etc.), that is, while the driver is driving. This is the range displayed at the scale ratio, which is a map display that is easy to refer to. This makes it possible to show the driver a map image 75 that can more appropriately support driving.

For example, in the display state shown in FIG. 11, the CPU 41 accepts a free scale change by the user 4 based on a touch operation on the touch panel 14. Further, for example, when the scale change button 131 of FIG. 11 is touch-operated to display FIG. 13, the CPU 41 fixes the map image 75 at a preset constant scale ratio. Therefore, for example, if the scale change button 131 is operated while the most enlarged map is displayed in FIG. 11, the map may be reduced by switching to FIG.

Further, when displaying the screen of FIG. 13, the CPU 41 displays in the balloon 133 the number of public permission candidate sites 111 that could not be displayed for the public permission candidate sites 111 that cannot be displayed on the map. For example, the CPU 41 totals the number of public permission candidate sites 111 that could not be displayed for each of the four directions, and displays the totaled number in the balloon 133. In the examples shown in FIGS. 11 and 13, the display of the four candidate sites 121, 122, 123, 124 located north of the current position mark 76 is omitted, and the two candidate sites 125 located in the east are omitted. The display of 126 is omitted, and it is displayed as a number in the balloon 133. Thereby, for example, when the driver wants to confirm the vicinity of the current position, he / she can operate the scale change button 131 to display the enlarged map shown in FIG. 13 for confirmation. Further, the public permission candidate site 111 that does not exist around the current position can be easily displayed by the balloon 133. For example, when displaying the enlarged map shown in FIG. 13, the CPU 41 maintains the scale of the map at a constant value until the scale change button 131 is operated again to switch to the display state shown in FIG. Therefore, even if the CPU 41 makes a negative judgment in S24 described later and executes S22 again, if it is a public permission candidate site 111 around the current position, it is displayed on the map, and it must be a public permission candidate site 111 around the current position. For example, increase the number of balloons 133.

The method of totaling the balloons 133 is not limited to 4 directions, and may be 16 directions or the like. Further, the CPU 41 may limit the ratio of automatically reducing the map to a certain range in the display process of FIG. 11 in S23. For example, when the CPU 41 posts a public permission candidate site 111 that is a predetermined distance or more from the current position mark 76, the balloon 133 in FIG. 13 does not reduce the map image 75 to the range including the public permission candidate site 111. Only the number of public permission candidate sites 111 may be displayed on the edge of the liquid crystal display 15. As a result, the information that cannot be divided by the automatic adjustment of the scale of the map can be easily displayed by the balloon 133 or the like. Further, the CPU 41 may have the same character size of the POI information 83 or the like in the display shown in FIG. 11 and the display shown in FIG. 13, and may reduce the character size according to the scale of the map. You may. Further, in the state of FIG. 11, when the scale ratio of the map is manually changed by the user 4, the CPU 41 hides the public permission candidate site 111, displays the balloon 133, and displays the characters according to the changed scale ratio. You may change the size of.

Further, in the information providing system 1 of the present embodiment, the evaluation of the user 4 for each disclosure permission candidate site 111 can be aggregated. More specifically, the CPU 41 increases the number of evaluations (an example of the evaluation information of the present invention) displayed next to the evaluation button 114 based on the touch operation of the evaluation button 114. For example, when the CPU 51 of the communication terminal 5 detects a touch operation on the evaluation button 114 of any of the public permission candidate sites 111 displayed in the map display field 71, the information related to the touch-operated public permission candidate site 111 and the user Information is transmitted to the navigation device 3. The CPU 41 of the navigation device 3 increases the number of evaluations of the public permission candidate site 111 whose evaluation button 114 is touch-operated based on the information received from the communication terminal 5 in S23 of FIG.

For example, the CPU 41 increases the number of evaluations of the evaluation button 114 by one each time the user 4 touches the evaluation button 114 only once. As a result, the number of evaluations from each of the users 4A to 4D for each public permission candidate site 111 can be totaled. For example, the user 4 has an evaluation button for the public permission candidate site 111 that he / she wants to see the POI information 83 and the poster's comment 112 from among the plurality of public permission candidate sites 111 displayed in the map display field 71. Touch the 114. As a result, the number of evaluations can be increased, and the intention to go to the public permission candidate site 111 can be appealed to the other user 4. Further, the CPU 41 stores the information of the evaluation number received from the communication terminal 5 in the destination information 32. The CPU 41 displays the history information described later based on the evaluation number information (evaluated user information and evaluated time information) accumulated in the destination information 32 (see FIGS. 15 and 16).

The touch operation of the evaluation button 114 may be prohibited for the public permission candidate site 111 posted by the poster of the public permission candidate site 111. That is, for any public permission candidate site 111, the operation of increasing the evaluation number by the user 4 who posted the public permission candidate site 111 may be prohibited, and the evaluation number from the user 4 other than the poster may be totaled. Further, the communication terminal 5 and the navigation device 3 may be controlled so that one user 4 can operate the evaluation button 114 only once (evaluate only once) for one public permission candidate site 111. Further, the navigation device 3 may accept the operation of the evaluation button 114 on the liquid crystal display 15.

Further, in the display change process of S23, the CPU 41 changes the display mode of the public permission candidate site 111 based on the evaluation number of the evaluation buttons 114. For example, as shown in the public permission candidate site 126 in FIG. 11, the CPU 41 does not display the POI information 83 or the comment 112 for the public permission candidate site 111 having an evaluation number of zero. , Only the evaluation button 114 and the history display icon 116 are displayed. That is, the CPU 41 uses a simplified display mode for the public permission candidate site 111 having an evaluation number of zero. Thereby, for example, the public permission candidate site 111 can be reduced and displayed until it is evaluated by the user 4 other than the poster. Further, the user 4 who posts the public permission candidate site 111 operates the evaluation button 114 for the public permission candidate site 111 for which he / she wants to display the POI information 83, and increases the number of evaluations by one by himself / herself to the other user 4. The posted information on the candidate site for public permission 111 (POI information 83 and comment 112) can be appealed. Alternatively, the posting user 4 can simplify and display less recommended shops and the like by setting the evaluation number to zero for the public permission candidate site 111 that does not want to display the POI information 83.

Further, in the display change process of S23, when the evaluation number of any public permission candidate site 111 increases from zero to 1, the CPU 41 stops displaying the simplification of the public permission candidate site 111, and POI information 83 and comment 112. Is displayed. As a result, the POI information 83 and the like can be displayed at the timing when the user 4 evaluates the public permission candidate site 111.

The CPU 41 is not limited to the number of evaluations, and for example, the candidate site 111 for publication permission without a comment 112 may be simplified and displayed, and the candidate site 111 for publication permission may be simplified and displayed according to the number of evaluations and the number of comments. You may. Further, the CPU 41 displays the POI information 83 and the comment 112 when the public permission candidate site 111 is displayed on the map image 75, and when the evaluation number is zero after a certain period of time, the POI information 83 and the comment 112 are displayed. It may be erased for simplification and displayed. As a result, the POI information 83 and the like are displayed for a certain period of time, and when the user 4 who sees the POI information 83 and the like does not evaluate the public permission candidate site 111, it can be displayed in a simplified manner. Alternatively, the CPU 41 may always display only the POI information 83 at the public permission candidate site 111 even if the evaluation number is zero.

Further, in the display change process of S23, as shown in FIG. 11, the CPU 41 further enlarges and displays the information related to the public permission candidate site 111 as the number of evaluations increases. In the example shown in FIG. 11, the POI information 83 and the comment 112 of the public permission candidate site 122 having the evaluation number of 2 are displayed in a larger scale than the public permission candidate sites 121, 124, 127, 128 having the evaluation number of 1. Has been done. Further, the POI information 83 and the comment 112 of the public permission candidate site 123 having an evaluation number of 3 are displayed in a larger scale than the public permission candidate site 122 having an evaluation number of 2. As a result, the user 4 can be made to recognize the evaluation number by the size of the public permission candidate site 111.

Further, in the display change process of S23, the CPU 41 displays the guide route 117 to the public permission candidate site 111 displayed in S22, that is, newly displayed on the map image 75, as shown in FIGS. 10 and 11. To do. The CPU 41, for example, guides the route based on the information (address, etc.) required for the route search of the public permission candidate site 111 received from the communication terminal 5 in S8 described above, the search data of the map information DB 31 of the data recording unit 12, and the like. The route search of 117 is executed. Further, the CPU 41 calculates the estimated arrival time when traveling from the current position to the public permission candidate site 111 along the searched guide route 117 based on the search data of the map information DB 31 and the like. The CPU 41 displays the calculated estimated arrival time in association with the public permission candidate site 111. For example, the CPU 41 displays the estimated arrival time near the guide route 117 (see FIGS. 10 and 11). As a result, information on the estimated arrival time to each public permission candidate site 111 can be easily shared by a plurality of users 4.

Further, in the display change process of S23, the CPU 41 changes the display mode of the public permission candidate site 111 based on the relationship between the estimated arrival time and the business hours of the public permission candidate site 111 and the regular holiday of the public permission candidate site 111. To do. The business hours and regular holiday information can be detected in S8 based on the information received from the communication terminal 5. For example, when the time obtained by adding the estimated arrival time to the current time has passed the business hours, the CPU 41 changes the display mode of the public permission candidate site 111. Further, when today's date or day of the week is a regular holiday, the CPU 41 changes the display mode of the public permission candidate site 111.

The CPU 41 fills and displays the POI information 83 and the evaluation button 114 with, for example, an achromatic light gray color, as shown in the public permission candidate site 124 and the public permission candidate site 125 having a zero evaluation number in FIG. This makes it possible to visually and easily display shops that are closed on regular holidays and shops that are closed even when they arrive. Although not shown in FIG. 10, the comment 112 may be similarly filled with a gray color. In addition, operations (addition of comment 112 and destination setting described later) for the public permission candidate site 111 outside business hours or on regular holidays may be prohibited. Further, as shown in FIG. 11, the CPU 41 does not search or display the guide route 117 for the public permission candidate sites 126 having a zero evaluation number and the public permission candidate sites 124 and 125 such as regular holidays. It's good.

The CPU 41 executes S24 after executing S23. In S24, the CPU 41 determines whether or not the setting of the public permission candidate site 111 as the destination has been accepted from the displayed public permission candidate sites 111. When the CPU 41 determines that the destination setting is not accepted (S24: NO), the process from S21 is executed again, the reception process of another public permission candidate site 111, the display process of the public permission candidate site 111, and the display are performed. Execute the change process as appropriate. As a result, the CPU 41 periodically collects information related to the public permission candidate site 111 from the communication terminal 5 of each user 4, color-codes the public permission candidate site 111 collected from each user 4, and displays the liquid crystal display 15 ( It is displayed in the map display field 71) (see FIG. 11). In addition, the CPU 41 automatically adjusts the scale of the map, displays according to regular holidays, and the like.

On the other hand, the user 4 operates, for example, the touch panel 14 of the navigation device 3 to set a destination from among the public permission candidate sites 111 displayed on the map. When the CPU 41 determines that the destination setting has been accepted in S24 (S24: YES), the CPU 41 displays the public permission candidate site 111 (POI information 83, etc.) set as the destination in a dark color (S25). As a result, the public permission candidate site 111 set as the destination can be displayed with emphasis compared to other public permission candidate sites 111. The method of setting the destination is not limited to the method of operating the navigation device 3. For example, the navigation device 3 may accept the setting of the destination by operating the communication terminal 5. Further, when the destination is set and the route guidance is executed to the destination, the CPU 41 may delete the guide route 117 to the public permission candidate site 111 other than the public permission candidate site 111 of the destination from the map. .. As a result, the guide route 117 being guided can be displayed in an easy-to-understand manner, leaving only the guide route 117 to the destination. Alternatively, the CPU 41 may display the color or color density of the guide path 117 to the destination differently from that of the other guide paths 117.

The CPU 41 executes S26 after executing S25. In S26, the CPU 41 executes route guidance to the public permission candidate site 111 set as the destination based on the guidance route 117. As a result, it is possible to execute the route guidance from the communication terminal 5 to the public permission candidate site 111 collected. When the CPU 41 executes S26, the CPU 41 ends the route guidance processing program shown in FIG. The CPU 41 executes the process from S21 again, and accepts the collection of a new public permission candidate site 111, the change of the destination, and the like. When the route guidance is started in S26, the CPU 41 does not have to execute the process from S21 until the route guidance is completed.

Subsequently, a comment addition processing program executed by the CPU 41 of the navigation device 3 will be described with reference to FIG. Here, the comment addition processing program is executed, for example, after the power of the navigation device 3 is turned on and the system is started. When the comment addition processing program displays the public permission candidate site 111 on the map and then receives the comment 112 about the displayed public permission candidate site 111 from the communication terminal 5, the received comment 112 is received as the public permission candidate site 111. This is a program that stores the comment 112 displayed or received in the destination information 32 as history information. The timing of starting the comment addition processing program is not limited to the time when the power is turned on as described above, and may be, for example, the timing when the public permission candidate site 111 is first displayed on the map. The comment addition processing program shown in the flowchart in FIG. 14 below is stored in, for example, a RAM 42 or a ROM 43 included in the navigation device 3 and is executed by the CPU 41.

First, in S31 shown in FIG. 14, the CPU 41 determines whether or not the comment has been accepted. The navigation device 3 displays the public permission candidate site 111 on the map of the liquid crystal display 15, and then accepts the comment 112 for the public permission candidate site 111. For example, the CPU 51 of the communication terminal 5 is based on the fact that the comment addition icon 115 of any public permission candidate site 111 is touch-operated while the public permission candidate site 111 shown in FIG. 10 is displayed in the map display field 71. , A screen (not shown) for inputting the comment 112 is displayed on the display 59. The CPU 41 displays, for example, a screen similar to the screen displaying the comment input field 77 shown in FIG. 7 on the display 59. When the CPU 41 receives the input of the additional comment 112, the CPU 41 transmits the received comment 112 to the navigation device 3. The method of accepting the comment 112 is not limited to the method using the communication terminal 5 described above, and may be directly accepted by, for example, the touch panel 14 of the navigation device 3.

The CPU 41 repeatedly executes the determination process of S31 in S31 until the comment 112 is received from the communication terminal 5 (S31: NO). When the CPU 41 determines that the comment 112 has been received from the communication terminal 5 (S31: YES), the CPU 41 executes S32. In S32, the CPU 41 determines whether or not to display three or more comments 112 in the public permission candidate site 111 to which the comment 112 is added (hereinafter, may be referred to as a target public permission candidate site 111). The CPU 41 of the present embodiment sets an upper limit number for the number of comments 112 to be displayed. For example, the CPU 41 displays up to two comments 112 in addition to the POI information 83, and stores the third and subsequent comments 112 in the destination information 32 as history information without displaying them on the map. As a result, the number of comments 112 displayed for one candidate site for public permission 111 can be limited, and the map can be prevented from becoming difficult to see. The CPU 41 may be set to 1 or 3 or more as the upper limit number, or the comment 112 may be added and displayed indefinitely without setting the upper limit number. Alternatively, the CPU 41 may set an upper limit number for the total number of comments 112 displayed on one screen without determining the number of comments 112 for each public permission candidate site 111.

Further, the upper limit may be set for the number of comments 112 at the time of posting of the public permission candidate site 111 displayed in S22 of FIG. For example, the CPU 51 may limit the number of comments 112 received for one public permission candidate site 111 to two in the process of S5 of FIG. Alternatively, when the CPU 51 receives three or more comments 112 for one public permission candidate site 111, all the comments 112 may be transmitted to the navigation device 3 as information on the public permission candidate site 111 in S8. Then, the navigation device 3 may display up to two comments 112 and accumulate the third and subsequent comments 112 in the destination information 32 without displaying them.

In S32, when it is determined that two or less comments 112, that is, comments 112 equal to or less than the upper limit number are displayed in the target public permission candidate site 111, the CPU 41 executes S33. In S33, the CPU 41 superimposes one or two comments 112 on the POI information 83 of the target public permission candidate site 111. When the CPU 41 executes S33, the process shown in FIG. 14 ends, and the process from S31 is executed again. As a result, the CPU 41 starts the process of accepting a new comment 112.

As shown in FIG. 11, for example, the POI information 83 is superimposed on the comment 112 posted by the user 4D and the comment 112 posted by the user 4B on the public permission candidate site 121 posted by the user 4C on the upper left. Has been done. As a result, the POI information 83 and the comment 112 posted by the arbitrary user 4 and the comment 112 posted by the other user 4 about the POI information 83 and the like are aggregated and displayed for one public permission candidate site 111. Can be done. By checking the display screens of the communication terminal 5 and the navigation device 3, the plurality of users 4A to 4D determine which user 4 desires which public permission candidate site 111 as the destination, and the public permission candidate site 111. It is possible to confirm which user 4 is making what kind of comment 112 about, and to share useful information for determining the destination.

Further, the CPU 41 executes S35 when it is determined in S32 that three or more comments 112, that is, comments 112 equal to or more than the upper limit number are to be displayed in the target public permission candidate site 111 (S32: YES). The CPU 41 determines in S35 whether or not there is a comment 112 set as fixed information. The fixed information referred to here is information that is always displayed on the map.

More specifically, FIG. 15 shows a display screen of history information displayed on the display 59 of the communication terminal 5. For example, the communication terminal 5 requests the navigation device 3 for the history information related to the public permission candidate site 111 based on the touch operation of the history display icon 116 of the public permission candidate site 111 displayed in the map display field 71. The navigation device 3 searches the destination information 32 for the history information related to the requested public permission candidate site 111, and responds to the communication terminal 5. The communication terminal 5 displays the history information shown in FIG. 15 based on the information received from the navigation device 3.

The key icon 141 shown in FIG. 15 indicates that the information to which the key icon 141 is added is fixed information. In this embodiment, for example, POI information 83 is set as fixed information as an initial setting. Therefore, the POI information 83 is displayed in a balloon 133 when the evaluation information is simply displayed at zero or the like (see the public permission candidate sites 125 and 126 in FIG. 11) or when it cannot be displayed on the map image 75 (FIG. 13). Except for (see), etc., it is basically displayed at the candidate site for permission to publish 111.

Further, the communication terminal 5 displays the fixed information at the top on the history information screen. Therefore, the communication terminal 5 basically displays the POI information 83 at the top of the screen. The communication terminal 5 displays the comment 112 in chronological order from top to bottom under the POI information 83. Further, the communication terminal 5 displays the evaluation history 142 from each user 4 in chronological order as history information. The evaluation history 142 is a history of the touch operation of the evaluation button 114 described above. The communication terminal 5 changes and displays the colors of the comment 112 and the evaluation history 142 for each user 4. As shown in the evaluation addition button 143 of FIG. 15, the communication terminal 5 may accept the evaluation of the displayed public permission candidate site 111 on the history information screen.

Further, in the information providing system 1 of the present embodiment, any comment 112 can be set as fixed information. For example, when a touch operation or the like is performed on an arbitrary comment 112 on the history information display screen shown in FIG. 15, the communication terminal 5 may set the comment 112 as fixed information. FIG. 16 shows a state in which the comment 112 is set as fixed information. As shown in FIG. 16, the communication terminal 5 displays the key icon 141 to the right of the comment 112 set as the fixed information, and is below the POI information 83, that is, other information other than the POI information 83 of the fixed information. Above, the comment 112 newly set as fixed information is displayed. As a result, fixed information can be displayed with priority.

In the present embodiment, except for the POI information 83, the display of up to two comments 112 on the map is restricted. In other words, only up to two comments 112 can be displayed on the map. Therefore, the communication terminal 5 accepts up to two comments 112 as fixed information in the history information. As shown in FIG. 16, for example, information desired to be known by another user 4, such as advantageous coupon information and coupon URL, can be preferentially displayed on a map or on a history information screen as fixed information. The navigation device 3 and the communication terminal 5 do not have to process the POI information 83 as fixed information.

In S35 of FIG. 14, the CPU 41 executes S36 when it determines that the comment 112 set as fixed information exists (S35: YES), and executes S37 when it determines that it does not exist (S35: NO). In S36, the CPU 41 gives priority to the comment 112 of the fixed information, and displays up to two comments 112 on the map. Further, when the fixed information comment 112 is one, the CPU 41 displays the latest comment 112, that is, the comment 112 received in S31. The CPU 41 executes S39 after executing S36. In S39, the CPU 41 stores the third and subsequent comments 112 that could not be displayed in the destination information 32 as history information.

On the other hand, the CPU 41 displays up to two latest comments on the map in S37. After executing S37, the CPU 41 stores the third and subsequent comments 112 that could not be displayed in S39 in the destination information 32 as history information. After executing S39, the CPU 41 ends the process shown in FIG. The CPU 41 executes the process from S31 again, and executes the process of accepting a new comment 112.

As a result, for example, the latest two comments 112 are displayed on the map until the fixed information comment 112 is set (S37). Further, when one comment 112 of the fixed information is set, the comment 112 of the fixed information is always displayed, and the latest one comment 112 is displayed (S36). Further, when two fixed information comments 112 are set, the two comments 112 are always displayed. In this way, the navigation device 3 of the present embodiment displays the comment 112 posted by each user 4 based on the setting of the fixed information. The navigation device 3 may accept the release of the fixed information once set. Further, the navigation device 3 may display the older comment 112 with priority instead of giving priority to the latest comment 112. Further, the navigation device 3 does not have to accept the setting of the fixed information of the POI information 83 and the comment 112.

As described in detail above, the CPU 41 of the navigation device 3 according to the present embodiment collects the public permission candidate sites 111 set by the plurality of users 4 in each of the plurality of communication terminals 5 (S21). The CPU 41 aggregates and displays the collected information (POI information 83, comment 112, etc.) related to the plurality of public permission candidate sites 111 on one map (S22).

For example, when the public permission candidate sites 111 set by each user 4 are displayed on a split screen in which one screen of the liquid crystal display 15 is divided, it is difficult to grasp the positional relationship of the plurality of public permission candidate sites 111, and the user 4 It's hard to understand the whole picture. On the other hand, in the present embodiment, by displaying the information of the public permission candidate sites 111 set by the plurality of users 4 in one map image 75, the positional relationship of each public permission candidate site 111 can be understood. It can be easily displayed, and it becomes easy for a plurality of users 4 to share information on a candidate destination.

Specifically, for example, when a plurality of users 4 riding in a vehicle 2 of a shared service are having difficulty in deciding a destination through discussion because they are meeting for the first time, they supply each other's information through the communication terminal 5 (opinion). By exchanging), it is possible to search for a destination where all users 4 are more satisfied. Moreover, even the users 4 who meet for the first time can easily decide the destination.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the gist of the present invention.
For example, in the above embodiment, when the connection with the communication terminal 5 is disconnected, the navigation device 3 may delete the information about the communication terminal 5. For example, the navigation device 3 may delete the information of the POI information 83 and the comment 112 related to the disconnected communication terminal 5 from the destination information 32. Thereby, for example, in the navigation device 3 of the rental car used by an unspecified number of users 4, the leakage of personal information can be prevented by deleting the information.

Further, the navigation device 3 does not have to change the display mode such as color coding for each user 4. For example, the navigation device 3 may display the POI information 83 and the like of all the users 4 in the same color. Alternatively, the navigation device 3 may display the POI information 83 or the like in a different shape for each user 4.
Further, the navigation device 3 may execute color coding of the POI information 83 and the comment 112 for each communication terminal 5 instead of for each user 4.
Further, the navigation device 3 may display only the position of the public permission candidate site 111 without displaying the POI information 83 or the comment 112. That is, the navigation device 3 may only collect and display the candidate destination.
Further, the information providing system 1 does not have to accept the public / private setting (public permission candidate site 111 or private candidate site setting) for the destination candidate site. The navigation device 3 may collect candidate destinations set by each user 4 by searching or the like from each communication terminal 5, and may aggregate and display the collected candidate destinations on one map.
Further, the communication terminal 5 may display a comment relating to the non-public candidate site or the non-public candidate site only in its own setting screen field 72. In this case, the display of the communication terminal 5 and the display of the navigation device 3 are different from each other. As a result, the user 4 can confirm his / her private candidate site on the map of his / her own communication terminal 5 without displaying it on the navigation device 3 or the communication terminal 5 of another user 4.

Further, the configuration of the information related to the above-mentioned public permission candidate site 111 is an example. For example, the navigation device 3 does not have to display the user information 113 and the evaluation button 114 on the public permission candidate site 111.
Further, the navigation device 3 does not have to accept the evaluation of the public permission candidate site 111.
Further, the navigation device 3 does not have to change the display mode of the public permission candidate site 111 according to the number of evaluations.
Further, the navigation device 3 does not have to accumulate the maximum number of comments 112 or more as history information. For example, the user 4 may delete the displayed comment 112 and post a new comment 112.
Further, although the CPU 41 executes the gray color display change based on the business hours and the regular holidays in S23, the display may be changed based on at least one of the business hours and the regular holidays. Further, the CPU 41 does not have to execute the display change based on the business hours and the regular holidays.

Further, the navigation device 3 does not have to perform the scale adjustment of the map for displaying all the comments 112, which was executed in S22.
Further, the navigation device 3 does not have to display the scale change button 131 on the liquid crystal display 15 and does not accept the switching of the display around the current position.
Further, the communication terminal 5 does not have to execute the search for the candidate destination in S3 and S4. For example, the user 4 may manually input a photo or shop information on the communication terminal 5 and post it to the navigation device 3.
Further, in the above-described embodiment, the display screen of the liquid crystal display 15 of the navigation device 3 is displayed on the communication terminal 5, but it is not necessary to display the display screen. That is, it is not necessary to display the map image 75, the current position mark 76, the public permission candidate site 111, and the like on the communication terminal 5. In this case, the user 4 can confirm the public permission candidate sites 111 aggregated on the map by the navigation device 3.

Further, in the above embodiment, the case where all the users 4A to 4D are on the vehicle 2 has been described, but the present invention can also share information with the user 4 who is not on the vehicle 2. FIG. 17 shows the configuration of another example information providing system 1. In another example shown in FIG. 17, the case where the users 4A, 4B, and 4C are on board the vehicle 2 and the user 4D is picked up while heading for the destination is shown. In this case, the communication terminal 5 of the user 4D outside the vehicle can communicate with the navigation device 3 via the communication network 6. Even in such a case, in addition to the users 4A to 4C in the vehicle, the information and the comment 112 of the candidate site for disclosure permission 111 can be aggregated in the navigation device 3 from the user 4D outside the vehicle, and the aggregated information can be displayed and shared.

Further, as in the user display 151 and the position display 152 shown in FIG. 17, the positions of the users 4 inside and outside the vehicle may be displayed on the map with identification information, and the positions may be shared on the map. Further, the time until the vehicle 2 arrives may be displayed to the user 4D outside the vehicle. The arrival notification 153 may be displayed on the communication terminal 5 of the user 4D in accordance with the arrival at the position of the user 4D, or the arrival may be notified by a buzzer or the like.

Further, in the above-described embodiment, the information providing system 1 including one navigation device 3 has been described, but the information providing system 1 may include two or more navigation devices 3. For example, as shown in FIG. 18, the navigation device 3 of the vehicle 2A and the navigation device 3 of another vehicle 2B may share information on the candidate destination. The two navigation devices 3 may transmit information via the communication network 6 or vehicle-to-vehicle communication. As a result, information on the candidate destination can be shared between the users 4 who ride on the different vehicles 2A and 2B, respectively.

Further, as shown in FIG. 18, the navigation device 3 displays only the current position mark 76 of the own vehicle as shown in the vehicle 2A, and the current position of the own vehicle and another vehicle as shown in the vehicle 2B. The state in which the mark 76 is displayed may be switched by the scale change button 131. Further, when the navigation device 3 displays only the current position mark 76 of the own vehicle like the vehicle 2A, the navigation device 3 may display only the POI information 83 and the comment 112 posted by the user 4 of the own vehicle. Further, when the navigation device 3 also displays the current position mark 76 of another vehicle like the vehicle 2B, the navigation device 3 may display all the POI information 83 and the like of the own vehicle and the user 4 of the other vehicle.

Further, in the present embodiment, the navigation device 3 performs the route search process, but the route search process may be performed by an external server communicably connected to the navigation device 3. When the external server is used, information necessary for route search such as the current position may be transmitted from the navigation device 3 to the external server together with the route search request.
Further, the information providing device of the present invention can be applied to a device having a function of displaying a candidate destination, etc., in addition to the navigation device. For example, it can be applied to mobile phones, smartphones, tablet terminals, personal computers and the like (hereinafter referred to as mobile terminals and the like). It can also be applied to a system composed of a server, a mobile terminal, or the like. In that case, each step of the registration processing program (FIG. 4), the route guidance processing program (FIG. 4), and the comment addition processing program (FIG. 14) described above may be performed by any of the server, the mobile terminal, and the like. good.
