  The route search unit 42 is activated by the navigation control function 31-1, and the latitude and longitude of the current location where the navigation device NV is calculated, calculated by the positioning unit 34, and the latitude and longitude of the destination obtained by the destination information analysis unit 41. A route from the current location to the destination is searched from the longitude and the road information stored in the navigation storage unit 43. Then, the route is displayed on the display unit 35 together with a map around the route. The surrounding map can be obtained by cutting out a part of the map information stored in the navigation storage unit 43.

  The navigation control function 31-1 starts to operate by a predetermined operation of the input unit 36 and inputs a destination address by the operation of the input unit 36. Then, the address is stored in the navigation storage unit 43 as destination information. Then, the route from the current location to the destination is displayed on the display unit 35 by sequentially operating the destination information analysis unit 41 and the route search unit 42.

  When inputting the destination address, the navigation control function 31-1 refers to the address information stored in the navigation storage unit 43, and displays a list of higher-level addresses (prefectures) on the display unit 35. The information is displayed, and one of them is input by selecting it by operating the input unit 36. Next, similarly, one is entered from a list of lower-level addresses (city / town / village) included in the inputted address, and finally, an address is inputted.

  Further, when the destination information is received via the short-range wireless transmission / reception unit 33, the navigation control function 31-1 starts the operation and causes the navigation storage unit 43 to store the destination information. Then, the route from the current location to the destination is displayed on the display unit 35 by sequentially operating the destination information analysis unit 41 and the route search unit 42.

  The operation of searching for a route to the destination in the navigation system configured as described above according to the first embodiment of the present invention will be described with reference to the sequence diagram shown in FIG. This control operation is divided into two parts. First, it is controlled by the destination information transmission control function 11-1 of the mobile communication device MS-1, for example, an object of a format such as vNote or vMessage defined by IrMC. This is an operation for generating certain destination information. Secondly, the latitude and longitude of the destination is obtained from the destination information which is the object controlled by the navigation control function 31-1 of the navigation device NV, and the route from the current location to the destination is searched. It is an operation to display.

  The destination information transmission control function 11-1 starts an operation based on a predetermined key operation of the input unit 16 (step S101), and stores bar code information, electronic mail, and web stored in the application storage unit 23. An object as destination information is generated from one of the contents (step S102). The generation of the object includes various operations depending on the information stored in the application storage unit 23 as described below.

  First, when the information stored in the application storage unit 23 is an object, the object is used as it is. In particular, the barcode information is highly likely to be an object. Second, when the barcode information is a URL indicating a web page, the destination information transmission control function 11-1 causes the browser unit 22 to access the address. Then, a vNote object is generated from the obtained web content.

  Third, a vMessage object is generated from the email. The e-mail may be a received e-mail, an e-mail that has not been sent or has been sent for transmission. Fourth, a vNote object is generated from web content.

  Note that when generating a vNote object from web content, character string information is extracted from the web content, but the present invention is not limited to this. In addition to this, characters may be extracted by performing character recognition on an image included in web content.

  In addition to the above, for example, when the memo pad management unit (not shown) stores the memo pad input by the key operation of the input unit 16 in the application storage unit 23, the destination information transmission control function 11-1 Then, a vNote object is generated from one item of the stored notepad.

  The predetermined key operation for starting the operation of the destination information transmission control function 11-1 is a key operation during operation of the barcode analysis unit 19, the e-mail transmission / reception unit 21, or the browser unit 22. May be. For example, the bar code analysis unit 19 transmits the bar code information, the e-mail transmission / reception unit 21 transmits the e-mail, or the browser unit 22 displays the web content on the display unit 15 by a key operation. Each of the control functions 11-1 generates destination information from the displayed barcode information, e-mail, or web content.

  Furthermore, the predetermined key operation may also serve as a key operation for operating the barcode analysis unit 19, the e-mail transmission / reception unit 21, or the browser unit 22. For example, when a key operation for operating the bar code analysis unit 19 is also performed, the user of the apparatus directs the camera 19a toward the bar code and performs a single key operation so that the bar code analysis unit 19 is operated. When the URL indicating the web page is obtained by analyzing the barcode, the browser unit 22 is made to access the web page identified by the URL, and the destination information transmission control function 11-1 Generate destination information from the content.

  When the object is generated, the destination information transmission control function 11-1 requests the short-range wireless transmission / reception unit 18 to establish a short-range wireless communication link with the navigation device NV and to connect using the OBEX protocol. (Step S103). In accordance with this request, the short-range wireless transmission / reception unit 18 establishes a link with the short-range wireless transmission / reception unit 33 of the navigation device NV and establishes connection using the OBEX protocol (step S104), and completes the connection for destination information transmission control. It responds to the function 11-1 (step S105).

  Then, the destination information transmission control function 11-1 requests the short-range wireless transmission / reception unit 18 to transmit the generated object to the navigation device NV (step S106). In accordance with this request, the short-range wireless transmission / reception unit 18 transmits the object to the short-range wireless transmission / reception unit 33 of the navigation device NV (step S107).

  The short-range wireless transmission / reception unit 33 transmits the received object to the navigation control function 31-1 (step S108). When the navigation control function 31-1 receives the object, it responds to the short-range wireless transmission / reception unit 33 with the completion of reception (step S 109), and the short-range wireless transmission / reception unit 33 sends to the short-range wireless transmission / reception unit 18. A response indicating completion of reception is sent (step S110). Upon receiving the reception completion response from the short-range wireless transmission / reception unit 33, the short-range wireless transmission / reception unit 18 responds to the destination information transmission control function 11-1 with the completion of object transmission (step S111).

  Then, the destination information transmission control function 11-1 requests the short-range wireless transmission / reception unit 18 to disconnect the link established in steps S103 to S105 (step S112). The short-range wireless transmission / reception unit 18 disconnects the link with the short-range wireless transmission / reception unit 33 (step S113), and responds to the destination information transmission control function 11-1 with the completion of the disconnection (step S114). Thus, the route search operation to the destination performed by the destination information transmission control function 11-1 of the mobile communication device MS-1 is completed.

  On the other hand, the navigation control function 31-1 that has received the object in step S108 requests the destination information analysis unit 41 to analyze the object (step S121), and the destination information analysis unit 41 performs the analysis (analysis). As a result, the latitude and longitude of the destination are obtained.) The completion of analysis is responded to the navigation control function 31-1 (step S122).

  Then, the navigation control function 31-1 requests the route search unit 42 to search for a route to the destination with the analysis result obtained by the destination information analysis unit 41 (step S 123), and the route search unit 42. Searches for the route and causes the display unit 15 to display the obtained route (step S124). In addition, when the analysis result is not obtained by the destination information analysis unit 41, the navigation control function 31-1 does not request the route search unit 42 to search for a route to the destination (not shown).

  Next, the operation of the destination information analysis unit 41 will be described in detail with reference to the flowchart shown in FIG. The destination information analysis unit 41 is activated by the navigation control function 31-1 and starts operating (step S41a). At this time, destination information is given. The destination information is an object defined by IrMC.

  The destination information analysis unit 41 analyzes the destination information and determines whether a URI (Uniform Resource Identifier) indicating the destination included in the object is obtained (step S41b). Here, the URI indicating the destination is a URI indicating the latitude and longitude, a URI indicating the address, and a URI indicating the fixed telephone number. A plurality may be obtained.

  When the URI indicating the destination is not obtained, the destination information analysis unit 41 parses the object, that is, performs morphological analysis, and determines whether information for identifying the destination is obtained (step S41c). ). Here, the information for identifying the destination is information for identifying the latitude and longitude, information for identifying the address, and information for identifying the fixed telephone number. A plurality may be obtained.

  When the URI indicating the destination is obtained in step S41b and when the information for identifying the destination is obtained in step S41c, the destination information analysis unit 41 determines the obtained URI / information (step S41d) If the obtained URI / information is a fixed telephone number, the telephone number address correspondence stored in the navigation storage unit 43 is referred to convert the address into an address (step S41e).

  If the obtained URI / information is latitude and longitude or an address, and the obtained URI / information is a fixed telephone number, and the fixed telephone number is converted into an address in step S41e, the destination The information analysis unit 41 displays the obtained latitude and longitude and / or address on the display unit 15 and requests an operation of the input unit 16 to confirm the confirmation. If there are a plurality of obtained latitudes and longitudes or addresses, one of them is selected by operating the input unit 16 (step S41f). In the case of this display, when the obtained information is latitude and longitude, the address information stored in the navigation storage unit 43 is referred to convert the latitude and longitude into an address. Then, the destination information analysis unit 41 displays the address obtained by the conversion together with the latitude and longitude, or only the converted address instead of the longitude and latitude on the display unit 15.

  In this display, the destination information analysis unit 41 may also display the distance from the current location to the destination. In this case, when the obtained information is an address, the address information stored in the navigation storage unit 43 is referred to convert the address into latitude and longitude, and the obtained latitude or longitude converted and The distance is calculated and displayed from the latitude and longitude of the current location. The latitude and longitude of the current location are measured by the positioning unit 34. In addition, when displaying the above, the destinations may be sorted according to the distance, and displayed, for example, in ascending order of the distance. Further, the display based on the URI obtained in step S41b may be displayed first. This is because the accuracy of the destination is considered higher.

  In this display, the destination information analysis unit 41 may not display the latitude and longitude of the destination or the address on the display unit 15 when the calculated distance is larger than a predetermined value. This is because it may be determined that the destination is not the destination. The predetermined value is appropriately several hundred kilometers when the navigation device NV is a vehicle-mounted device, and about ten kilometers when the navigation device NV is a portable device, but is not limited thereto. It may be set by operating the input unit 16.

  As described above, after the destination is confirmed or selected, the destination information analysis unit 41 notifies the navigation control function 31-1 of the latitude and longitude of the destination (step S41g), and ends the operation ( Step S41h). In addition, when the information which identifies the destination is not obtained by step S41c, that is displayed on the display part 15 (step S41i), and operation | movement is complete | finished (step S41h).

  In the above description, when the URI indicating the destination is obtained in step S41b, the operation for obtaining the information for identifying the destination by parsing in step S41c is not performed. This is because, when the URI is obtained, it is considered that more reliable information can be obtained than by obtaining information by parsing, but the present invention is not limited to this. When a URI indicating the destination is obtained in step S41b, an operation of obtaining information for identifying the destination by parsing in step S41c may be performed. Thereby, information for identifying more destinations can be obtained.

  By the processing described above, appropriate destination information is often obtained from barcode information, e-mail, and web content. This is because, when a certain person is visited, the e-mail transmission / reception unit 21 is operated to display the e-mail from the person who is scheduled to visit, and the destination information transmission control function 11-1 is operated, thereby the e-mail. This is because an object, which is appropriate destination information, is generated from the signature including the person's address and fixed telephone number included in the signature.

  If you visit the person's home, the email sent by the person's personal email address will be sent by the person's email address in the organization if you visit the organization to which the person belongs. Display the email. In addition, an e-mail to a person who is scheduled to visit may be displayed. This is because, in particular, the e-mail created in a format conforming to a formal document often includes the address of the person's home or the organization to which the person belongs.

  Further, when going to a certain organization (hereinafter, including stores, restaurants, etc.), the browser unit 22 is often operated to refer to a web page created by the organization in order to check the location of the organization. . Therefore, by operating the destination information transmission control function 11-1 while referring to the page, an object that is appropriate destination information from the address or fixed telephone number of the organization that is normally included in the web content of the page. Is generated. Note that URLs indicating web pages are often printed as two-dimensional barcodes in organization advertisements, and the web page is referred to by causing the barcode analysis unit 19 to analyze the barcode. There are many things.
