  With reference to FIG. 1 which shows the structure of the whole information delivery system of this invention, the utilization form of the information delivery system 100 of this invention is demonstrated. In FIG. 1, the user A who is the owner of both the car navigation device 70 (or the portable computer 90) and the PC 10 installed in the home of the user A heads for a car equipped with the car navigation device 70. A spot considered as one of destinations, for example, a site operated by restaurant C is accessed. On a browser (information browsing software) of the PC 10, a display screen 30 of a site of a certain restaurant (hereinafter referred to as restaurant C) is displayed. The display screen 30 has a button 32 for accepting the start of execution of processing for transferring spot information about the restaurant C to the server 50 at a predetermined URL (Uniform Resource Locator) in addition to the content 31 that is information about the restaurant C. (Hereinafter, this button is referred to as a mobile link button 32). A user A who wants to use the spot information of the restaurant C with his / her car navigation device 70 clicks the mobile link button 32 displayed on the browser of the PC 10 by using a pointer of the PC 10, for example, a mouse. . When the user A clicks the mobile link button 32, the spot information of the restaurant C is transferred to the server 50 having a predetermined URL. The transferred spot information is, for example, the location data (latitude, longitude) of the restaurant C, the spot name, business hours, regular holidays, telephone numbers, classification codes, and the like. As will be described in detail later with reference to the flowcharts of FIGS. 3 and 4, at this stage, the server 50 acquires identification information about the user A from the browser of the PC 10 and performs user authentication. Further, the user A accesses not only the spot information of the restaurant C but also other desired sites, clicks the mobile link button 32 provided on those sites, and also transfers the spot information regarding other spots to the server 50. be able to.

  On the other hand, when the user A gets into the car and the navigation device 70 is activated, the download software of the car navigation device 70 accesses the server 50 via the mobile phone 71 connected to the car navigation device 70, Using the identification information of user A, the spot information already transferred to the server 50 is automatically downloaded. That is, the user A accesses the server 50 from the information terminal device such as the car navigation device 70 by accessing the desired site using the PC 10 at home and clicking the mobile link button 32 on the site. Thus, it is possible to automatically download spot information about the site. In the car navigation device 70, the downloaded spot information is used by the navigation application of the car navigation device 70 to display the location of the restaurant C on the map and to calculate the route with the restaurant C as the destination. The

  The car navigation device 70 includes a GPS receiver, map data, a CPU that executes a navigation application, a memory, a storage device such as a flash card, an interface for connecting to a mobile phone, and hardware components such as a user interface. Become. The navigation application also provides a route calculation function for estimating the vehicle position based on the positioning result by the GPS receiver and the map matching function based on the map data, and displaying the route to the destination set through the user interface. Have. These hardware components are not particularly shown because they may be generally known.

  2 to 8 illustrate details of a series of processes until the user A accesses a site and clicks the mobile link button 32, thereby transferring the spot information of the site to the server 50. FIG. Details of operations of the PC 10, the site, and the server 50 will be described with reference to these drawings. In the following description, it is assumed that the user A accesses a site operated by the restaurant C.

  FIG. 2 is a diagram for explaining the movement of data transmission / reception between the user A (PC 10 of the user A, etc.), the site of the restaurant C, and the server 50. User A uses the home PC 10 to access the site of the restaurant C for which information is desired to be displayed, displays the content of the site on the browser of the PC 10, and the mobile link displayed on the display screen of the browser The button 32 is clicked (FIG. 2 (a)). The mobile link button 32 is designated with a URL for starting a program on the server 50 side, for example, a CGI (Common Gateway Interface) script, and spot information of the restaurant C is encoded as a parameter in, for example, an HTML format. Comes with. Note that, as is generally known, CGI refers to a rule for starting a program on the side of a web server such as the server 50 in accordance with a request from the browser and exchanging data between the web server and the browser. The CGI script is a program activated by the web server side.

  When the mobile link button 32 is clicked by the user A and a request for the URL specified by the mobile link button 32 is sent to the server 50, the server 50 starts a CGI script corresponding to the URL. When the CGI script is activated, a user ID and a password are requested from the server 50 to the browser side of the PC 10 (arrow 55 in FIG. 2B). At this time, the user A inputs the ID and password in accordance with the ID and password input request displayed on the browser screen of the PC 10 (arrow 11), and can register the user A with the server 50. it can. As described above, once the user is registered in the server 50, the user A accesses any site from the next time on and clicks the mobile link button 32 of the site to store the spot information in the server 50. When transferring, it is possible to eliminate the need to input a user ID and password on the browser.

  Further, the server 50 issues a request to the browser of the PC 10 to confirm whether or not the mobile link button 32 is accepted (arrow 56). In response to this, the user A performs an input for approving the click on the confirmation request on the browser of the PC 10. When the approval of the click is obtained, the server 50 records, in the database 51, the spot information simultaneously transmitted from the browser of the PC 10 as the URL parameter for starting the CGI script in association with the identification information of the user A. .

  3 and 4 are flowcharts showing details regarding the operation described above with reference to FIG. When the mobile link button 32 is clicked (S1), a request for a URL for starting a program (CGI script) is made from the browser of the PC 10 to the server 50 that performs login (S2). Specifically, a URL that activates the CGI script of the server 50 is embedded in the mobile link button 32. When the program (CGI script) is activated in the server 50, the server 50 inquires of the browser of the PC 10 whether or not there is authentication information (ID and password) of the user A (S3). The inquiry of authentication information in step S3 uses, for example, a so-called cookie function for managing information between the server and the browser, and the server 50 sends the cookie information (authentication information) to the browser of the PC 10. This can be done by inquiring.

  If user A has once accessed any site and clicked the mobile link button 32 to transfer the spot information to the server 50, the cookie information is sent from the server 50 to the browser of the PC 10. If the cookie information is stored on the browser side, the server 50 can obtain the cookie information from the browser. In such a case, when the authentication (cookie) information is confirmed by the server 50 (S3: YES), the user ID and password included in the cookie information are received by the server 50 (S4). Next, the server 50 inquires identification information (user ID and password) registered in advance as a cookie function (S5), and authenticates that the user is already registered (S6).

  Next, the server 50 transmits data for urging the user A to confirm whether or not to accept the click of the mobile link button 32 to the browser of the PC (S7). In step S8, the browser of the PC 10 transmits to the server 50 data describing that the click is accepted corresponding to the data sent in the process of step S7. The server 50 receives the data (S9).

  Next, the server 50 activates a program for database storage processing (S10), and classifies the spot information sent as URL parameter data for CGI script activation for each user ID. 51.

  On the other hand, if the cookie information cannot be obtained from the browser of the PC 10 in step S3, the user A is the first user to use the spot information transfer service by the mobile link button 32, or the user A is not the first time. This is a case where the browser for the PC 10 is not set to save cookie information. In such a case, if the cookie information is not obtained in step S2 (S2: NO), the program of the server 50 displays on the browser screen of the PC 10 a prompt for input of the user ID and password. . FIG. 5 shows an example of a display prompting the user ID and password. As shown in FIG. 5, an e-mail address (e-mail address) can be used here as an example of the user ID.

  When user A has experience in information transfer using the mobile link button 32 and attribute data of the user A is registered in the server 50 (S13: YES), the user A is on the ID input screen 57. Then, the user ID and password are input (S14). Here, the user A does not input the user ID and password (that is, stores the cookie information) and automatically performs user authentication as in the above steps S3 to S6. If desired, check the check box 57a. When the transmission button 57b is clicked by the user A (S15: YES), the content input by the user A on the ID input screen 57 is transmitted to the server 50.

  On the server 50 side, it is determined whether or not the check box 57a is checked (S16). When the check box 57a is checked (S16: YES), the password entered by the user A on the ID input screen 57 and the user information independently issued by the server 50 are used as cookie information (recognition information). It is transmitted to the browser of the PC 10 (S17). In the browser of the PC 10, the received cookie information is stored in a storage device such as a hard disk (S18). When the next button is pressed, the process proceeds to step S4, and the server 50 receives cookie information from the browser of the PC 10.

  In step S16, when the check box 57a is not checked (S16: NO), the process proceeds to step S6, and the user A and the user using the password entered by the user A on the ID input screen 57 as the cookie function. Authentication is performed.

  On the other hand, when the user A has used the spot information transfer by the mobile link button 32 for the first time, the attribute data is not registered in the server 50 (S13: NO). 57, the cancel button 57c is clicked. When the click of the cancel button 57c is recognized by the program of the server 50 (S19: YES), the server 50 displays a guidance screen 59 (see FIG. 6) for registering user attribute data on the browser screen of the PC 10. (S20).

  When the user A clicks a pointer 59a marked “Go to member registration page” on the guidance screen 59, a screen 60 (see FIG. 7) for guiding the registration contents is displayed on the browser of the PC 10. As shown in FIG. 7, on the screen 60, approval of registration is urged (S23), and the user A clicks a box 60a in which “accept” is displayed when performing registration. It should be noted that the process can be terminated by clicking on the box 60b marked “not accepted”.

  When the user A clicks the box 60a written as “Accept”, the process proceeds to step 24, and the attribute data registration screen 58 (see FIG. 8) is displayed on the browser of the PC 10. User A inputs necessary items on the attribute data registration screen 58 (S25), and then clicks a send button 58b on the registration screen 58 (S26). The attribute data input on the registration screen 58 by clicking the send button 58b is transferred to the server 50 (S27).

  The program of the server 50 processes the transmitted attribute data (S28), adds user information and newly records it in the database 51, and creates a database (S29). Next, the server 50 starts sending information indicating that registration in the database is completed to the user A of the PC 10 (S30). In step S31, HTML format data indicating that the registration is completed is transmitted from the server 50 to the browser of the PC 10, so that the registration completion is displayed on the browser of the PC 10 and used. The person A recognizes that the registration is completed. Thereafter, the process proceeds to the process from step S14.

  FIG. 9 shows a case where the car navigation device 70 mounted on the car owned by the user A acquires the spot information stored in the database 51 of the server 50 by the process described above with reference to FIGS. 3 and 4. It is a figure showing the movement of data transmission / reception in FIG. FIG. 10 is a flowchart showing the details. In the car navigation device 70, when the power is turned on, a browser or mailer is activated, and when connection to the Internet is made via the mobile phone 71, download software for downloading data from the server 50 is activated. Is configured to do. The download software is a smart pull type software configured to automatically acquire spot information from the server 50 using the user ID and password of the user A registered in the download software in advance. Wear. Hereinafter, this download software is referred to as a smart pull application.

  In FIG. 9A, when the smart pull application logs in to the server 50 and requests transfer of spot information (arrow 73), a request for a user ID and a password is returned from the server 50 (arrow 61). When the smart pull application transmits the user ID and password (arrow 74), the server 50 performs user authentication based on the user ID and password. In FIG. 9B, when user authentication is performed by the server 50, spot information associated with the user ID of the user A in the database 51 is transferred to the car navigation device 70 via the mobile phone 71. . In the server 50, when the spot information associated with the user ID is transferred, a flag is set for the spot information that has already been transferred to the user A, so that the transfer request from the user A is made. On the other hand, the difference information which is information of a part different from the content downloaded last time is transferred.

  This will be described in more detail with reference to the flowchart of FIG. First, in step S51, a browser or mailer is activated in the car navigation device 70, and an Internet connection is achieved (S52). Next, the smart pull application is activated (S53) and logged on to the server 50 (S54). Next, in step S55, a file transfer request is sent from the smart pull application to the server 50.

  In step S56, the smart pull application ID and password are requested from the program operating on the server 50 side to the smart pull application. The smart pull application sends the user ID and password previously written and held in the smart pull application to the server 50 (S57). The server 50 performs user authentication based on the user ID and password received from the smart pull application (S58). When user authentication is performed in step S58, the server 50 searches the database 51 for the one to which the received user ID is added (S59). When a user ID corresponding to the received user ID is found in the database 51 (S60), the presence or absence of a flag is identified for the file (spot information) associated with the received user ID in the database 51 ( S61). This flag is added by the program of the server 50 in order to identify that transfer has already been performed for the file associated with the user ID. The server 50 converts the spot information into a position information description format suitable for use in a portable information terminal such as a car navigation device, for example, POIX (Point Of Interest eXchange Language), and stores it in the database 51. ing. In addition to POIX, it is possible to use any format that can be used on mobile web, XML (eXtensible Markup Language) and other portable information terminals.

  In step S62, after a file without a flag, that is, difference information is selected, the selected file is sent to the smart pull application. The smart pull application receives the file from the server 51 (S63), and displays the number of received files on the desktop on the display screen of the car navigation device 70 (S64). Next, the smart pull application displays a message asking whether to obtain the received file on the display screen, and prompts the user of the car navigation device 70 to input confirmation (S65). When the user clicks an OK button for accepting the file acquisition via the user interface of the car navigation device 70 (S66), the file is stored in the registration list (that is, the storage device of the car navigation device 70). (S67).

  Use of spot information obtained by the car navigation device 70 in a navigation application will be described with reference to FIGS. FIG. 11 shows a menu screen 77 of the navigation application. FIG. 11A shows that the user A selects an item 77 a of “Destination” on the menu screen 77 by operating an operation key that is a user interface of the car navigation device 70 in order to view the downloaded information. In addition, the “favorite” or “registration list” item 77b is selected. As a result, the data sorted according to the classification code in the spot information is displayed as shown in FIG. As shown in FIG. 11B, the items are classified into items “car & drive”, “play”, and “eat” by the classification code.

  FIG. 11C shows a screen after the “eating” item 77c is selected. According to the lower category of the classification code, they are sorted and displayed in the items of “fast food”, “sushi restaurant”, and “Chinese food”. Here, when the item “Chinese cuisine” 77d is selected, the spot names of the Chinese restaurants displayed in the order of Iueo or alphabet are displayed as shown in FIG.

  FIG. 12 shows a display screen when route calculation is performed with the restaurant displayed in FIG. 11D as the destination. When the user A selects the spot name portion 77e on the screen displaying the target restaurant (FIG. 12A), the navigation application uses the location data (latitude, longitude) and map data of the restaurant. Then, the location of the restaurant is indicated on the map screen with the cross key 77f. When the user A operates the operation key here, the destination is set and the route is calculated.

  On the other hand, FIG. 13 shows a case where the spot information of the restaurant displayed in FIG. 11D is displayed. As shown in FIG. 13A, when the “Guide” item 77g placed on the menu screen is selected, spot information of the restaurant is displayed.

  FIG. 14 shows that when the car navigation device 70 does not have a smart pull application, the smart pull application is downloaded using a free download service of the smart pull application provided by a site operated by a car navigation device manufacturer or the like. It represents the case. FIG. 14A shows a screen 130 of a site operated by a car navigation maker. The screen 130 displays buttons 131 for downloading the smart pull application together with various contents. A user accessing this site can download the smart pull application by clicking the button 131. When the download is completed and the installation of the smart pull application is started, a screen 132 for prompting registration of user attribute data is displayed. When user A inputs user attribute data according to the screen 132, the smart pull application is displayed. These user attribute data are stored. The stored user attribute data is used to receive user authentication when the smart pull application is activated and a spot information transfer request is sent to the server 50.

  In the above description of the embodiment, the case where the user A uses the spot information using the car navigation device 70 has been described. However, as shown in FIG. 1, the user A uses the spot information. Needless to say, even if the portable information terminal to be used is the portable computer 90, the same functions as those described above for the car navigation device 70 can be realized.

  It is possible to share spot information acquired on one portable information terminal side between a plurality of portable information terminals having an infrared communication function such as IrDA.

  It goes without saying that various modifications and substitutions can be made with respect to the above-described embodiment. For example, in the above-described embodiment, the user collects information from the server in advance using a function provided by the mobile link button. However, the server 50 has a database in which useful spot information or the like and user identification information are associated with each other without requiring collection by the user, and provides useful spot information. Forms are also conceivable. Also in this case, the car navigation apparatus can automatically acquire useful spot information from the database of the server by the smart pull application.

  In addition, since information such as an e-mail address is stored in the server 50 as identification information of a user who uses the information distribution system 100, the server 50 uses the identification information to send a user's portable information terminal or It is possible to configure an advertisement distribution system for a service that automatically distributes store information such as restaurants and inns to PCs as store manager advertisements or sales promotions. In particular, since the store information collected by the user is stored as a history for each piece of identification information that can identify the user of the information distribution system 100, the database 51 in the server 50 stores the user based on the stored information. It is possible to distribute an advertisement having a high value for the user.
