The route data is data representing a traffic route including a road in the coordinate space, and includes node information and link information, for example. A node refers to an element point such as an intersection, an end point, or an inflection point that constitutes a traffic route, and node information is information such as latitude / longitude and type in which these elements exist. The link information is information representing the connection between nodes. The attribute data is associated with, for example, coordinates, nodes, and links in the above-described coordinate space, and represents attributes associated with the associated elements. The attribute data is, for example, information about the road corresponding to the link, specifically, information such as distance, one-way, inclination, etc., or information about the intersection corresponding to the node, specifically, an image of the information board at the intersection Includes information such as data.

  In general, route guidance includes a plurality of coordinate information including at least a start point and a destination, and in some cases including a transit point, and collates / searches route data based on the plurality of coordinate information, thereby guiding the route. It starts by generating guidance information that represents. The coordinate information of the start point may be acquired as, for example, a current position measured using a global positioning system (GPS) at the time of generating guidance information, or acquired by receiving user input. May be. In general, the coordinate information of the destination and the waypoint is acquired by receiving user input. Route guidance is performed using attribute data associated with the vicinity of the current position while collating the generated guidance information with current position information sequentially acquired using GPS.

  As a method of receiving user input when generating guide information, a method of displaying a map image on a display monitor in which a touch panel and a display panel are stacked and tracing the map image with a touch pen is known. (For example, patent document 1).

・ Operation of the map display system:
・ Guidance information generation processing:
FIG. 3 is a first diagram illustrating an example of the mode selection screen. FIG. 4 is a flowchart showing a processing routine of guidance information generation processing in the first embodiment. The guide information generation process is a process in which the main control unit 210 of the mobile terminal 200 generates guide information for original navigation described later (hereinafter also referred to as original navigation data) in accordance with the guide information generation program M10.

  When the user of the mobile terminal 200 instructs execution of the route guidance function, the mode selection screen shown in FIG. Two modes are prepared for the route guidance function of the mobile terminal 200 in this embodiment. The first mode is a normal navigation mode in which general route guidance is performed. Since route guidance in the normal navigation mode is well known, details thereof are omitted.

The second mode is an original navigation mode in which route guidance specific to the present embodiment is performed. The user generates original navigation data prior to selection of the original navigation mode. When the user instructs generation of original navigation data on the mode selection screen shown in FIG.
The guidance information generation process is started.

  When the guidance information generation process is started, the route trajectory reception unit M11 of the guidance information generation program M10 displays a route trajectory reception screen on the display panel 202 (step S10).

  FIG. 5 is a diagram illustrating an example of a route reception screen. Specifically, the path trajectory receiving unit M11 recognizes the current position by measuring the current position based on the radio wave received by the GPS receiver 201. The route trajectory receiving unit M11 transmits a designation of a range including the recognized current position to the map server 150, and acquires map image data of the designated range from the map server 150. In this embodiment, map image data is image data that draws a map image in a coordinate space on the earth surface represented by latitude and longitude (hereinafter referred to as ground coordinate space), and is associated with coordinates in the ground coordinate space. Image data in a vector data format or raster data format. The route trajectory receiving unit M11 displays the map image represented by the acquired map image data on the display panel 202 at a predetermined scale.

  Further, the route trajectory accepting unit M11 displays, as a route accepting screen, a message MS1 that prompts the user to input the route trajectory and an operation GUI for operating the display mode of the map image superimposed on the map image. . The operation GUI includes a slide bar RUI and a direction instruction button DUI, as shown in FIG. The slide bar RUI is a GUI for accepting a change in the scale of the map image from the user. The direction instruction button DUI is a GUI for receiving an instruction from the user to change the area displayed as the map image by scrolling the map image in a predetermined direction.

  Next, the route trajectory accepting unit M11 accepts a route trajectory from the user (step S20). FIG. 6 is a diagram for explaining acceptance of a route locus from a user. FIG. 7 is a diagram illustrating an example of a path trajectory received from a user.

  As shown in FIG. 6A, the user traces the map image displayed on the display panel 202 with the touch pen 230 and draws a locus of a route for which route guidance is desired (route locus). The path trajectory accepting unit M11 sequentially acquires position information indicating positions pressed by the touch pen 230 from the touch panel 203 superimposed on the display panel 202. The path trajectory accepting unit M11 displays the trajectory display line RL superimposed on the map image in accordance with the acquired position information. The path trajectory accepting unit M11 further collates the acquired position information with the map image data of the map image displayed on the display panel 202, and coordinates (in the ground coordinate space corresponding to a plurality of points on the trajectory ( NS, WE) is calculated (NS is a numerical value of latitude, and WE is a numerical value of longitude). More specifically, as shown in FIG. 6A, the coordinates (NSi, WEi (i) of points P0, P1, P2, P3,... Arranged in the order of input of the trajectory at a predetermined interval from the start point P0. = 0, 1, 2, 3, ...)) are calculated sequentially. The path trajectory receiving unit M11 sequentially calculates the calculated coordinates (NSi, WEi (i = 0, 1, 2, 3,...)) On the address space of the buffer area BF as shown in FIG. To store. Hereinafter, the coordinates on the ground coordinate space of the point Pi (i is an integer of 0 or more) on the map image are expressed as (NSi, WEi (i is an integer of 0 or more)).

  The plurality of coordinates are sequentially stored in the address space of the buffer area BF, so that the order in which the guide route corresponding to the input locus is formed can be specified. The plurality of coordinates may be received in such a manner that the order can be specified as described above. For example, the coordinates may be recorded with an identification ID representing the order, or may be recorded in a form that is sequentially assigned to the array variable. Also good.

  FIG. 7 is a diagram illustrating an example of a guidance route input as a route trajectory. In this embodiment, in order to allow a user to specify a flexible guide route, the input route trajectory is used as it is as a guide route. Even if the guide route deviates from the road drawn on the map image, the guide route is allowed as it is without correction. In the example of FIG. 7, a mark MS indicating the start point and a mark ME indicating the end point are added for the convenience of the user, but the guide route NR itself faithfully reproduces the trajectory input by the user. To do.

  When the guidance route is designated in the form of a route trajectory and the end button (FIG. 7) is pressed, the point / section designation receiving unit M12 of the guidance information generation program M10 receives a point or section on the guidance route from the user. The designation is accepted (FIG. 4: step S30).

  FIG. 8 is a first diagram illustrating reception of designation of points or sections. FIG. 9 is a second diagram illustrating reception of designation of points or sections. As shown in FIG. 8, the point / section designation receiving unit M12 is a screen for receiving the designation of a point or section, and a simplified route SR showing a guide route in a straight line together with a map image superimposed on the designated guide route NR. Is displayed outside the map image.

  The user presses an arbitrary position on the guide route NR or the simplified route SR with the touch pen 230 and designates a point or section on the guide route. When designating a point, after pressing one point on the guide route NR or the simplified route SR, the designation button is pressed. When specifying a section, after pressing two points on the guide route NR or the simplified route SR, the specification button is pressed. FIG. 8 shows a state where the user presses one point on the guide route NR. The point / section designation receiving unit M12 displays marking icons Pa and Pb indicating the pressed point on the guide route NR and the simplified route SR.

  FIG. 9 shows a case where two different points on the guidance route NR are indicated, but two points that are close or overlapped are indicated on the map image. For example, when the guide route NR specifies a route that passes through the same road twice, a part of the line representing the guide route NR may be very close to another part, or may overlap completely. possible. It may be difficult for the user to specify such a point on the line separately from the points on other adjacent lines. In the present embodiment, when there are two or more discontinuous points on the guide route NR near the pressed position on the map image, the point / section designation receiving unit M12 receives the two or more points. A marking icon is displayed for each of. Specifically, as illustrated in FIG. 9, a plurality of marking icons (Pa1, Pa2 in the example of FIG. 9) are displayed on the guidance route NR, and a plurality of marking icons (example of FIG. 9) are displayed on the simplified route SR. Then, Pb1 and Pb2) are respectively displayed. At the same time, the point / section designation receiving unit M12 displays on the display panel 202 a message MS2 that prompts one of the two or more points as candidates. These two or more points are clearly separated and displayed on the simplified route SR even though they are close or overlapped on the guide route NR superimposed on the map image. As a result, the user can easily select a point he / she intended from among the candidates without being confused by inputting a selection instruction on the simplified route SR.

  If the user is dissatisfied with the designated point or section, the user presses the return button to redo the designation. If the user is satisfied with the specified point or section, the user presses the end button and proceeds to the next step.

  Returning to FIG. 4, the description will be continued. When a point or section is specified on the guide route, the attribute information receiving unit M13 of the guide information generating program M10 receives a comment related to the specified point or section as attribute information from the user (step S40).

  FIG. 10 is a first diagram illustrating reception of attribute information. FIG. 11 is a second diagram illustrating reception of attribute information. As shown in FIG. 10, the attribute information receiving unit M13 displays a message MS3 for prompting the user to input a comment as guidance information and a comment input field CM on the display panel 202. The user inputs a comment using the character input key 205b of the mobile terminal 200. When the user inputs a comment and presses the end button (step S50: YES), the process proceeds to step S60, and guidance information is generated. On the other hand, when the user inputs a comment and presses the point / section designation button (step S50: NO), the processes of steps S30 and S40 described above are repeated. As a result, the user can input an arbitrary number of comments by designating points or sections on the guide route NR.

  FIG. 11 shows a screen in a state where seven comments are input and the input of the eighth comment is prompted. As shown in FIG. 11, on the guide route NR and the simplified route SR, in order to indicate the points or sections associated with the already input comments, comments having shapes different from those of the marking icons Pa and Pb described above are provided. Icons CPa and CPb are displayed.

  When the input of the comment by the user is completed (step S50: YES), the guidance information generation unit M14 of the guidance information generation program M10 generates original navigation data as guidance information (step S60).

  FIG. 12 is a diagram conceptually showing the contents of the original navigation data as guide information. The original navigation data 500 generated in step S60 includes a coordinate data portion 510 and an attribute data portion 520. The original navigation data 500 is generated as a data file in a predetermined file format.

  In the coordinate data portion 510, a plurality of coordinates stored in the buffer area BF so as to specify the order in step 20 in FIG. 4 are recorded in association with the coordinate ID indicating the order. In the coordinate data unit 510, a plurality of coordinates may be stored in a manner that allows the order to be specified. For example, the coordinates may be recorded in the address space on the data file in the order of addresses.

  An attribute ID and an attribute type are associated with a part of the coordinate information recorded in the coordinate data unit 510 so that the order can be specified. Specifically, an attribute ID for specifying the comment is associated with the coordinate information closest to the point on the guide route associated with the comment as the attribute information. In addition, the coordinate information closest to the start point of the section on the guidance route associated with the comment as the attribute information and the coordinate information closest to the end point of the section have an attribute ID for identifying the comment. Associated. Furthermore, an attribute type is associated with coordinate information associated with an attribute ID. The attribute type indicates a mode of association between attribute information and coordinate information. For example, in FIG. 12, the attribute type “P” indicates that the coordinate information specifies a point associated with the attribute information. The attribute type “S” indicates that the coordinate information specifies the start point of the section associated with the attribute information. The attribute type “E” indicates that the coordinate information specifies the end point of the section associated with the attribute information.

  For example, in the example of FIG. 12, an attribute ID “C1” and an attribute type “P” are associated with the m-th coordinate information (NSm, WEm). This indicates that the attribute information of the attribute ID “C1” is associated with a point on the guide route indicated by the coordinate information (NSm, WEm).

  On the other hand, the attribute information “C2” and the attribute type “S” are included in the j-th coordinate information (NSj, WEj), and the attribute ID “C2” and the attribute type “S” are included in the k-th coordinate information (NSk, WEk). "E" are associated with each other. This is because the attribute information of attribute ID “C2” has a point on the guide route indicated by the coordinate information (NSj, WEj) as a start point and a point on the guide route indicated by the coordinate information (NSk, WEk) as an end point. It is shown that it is associated with the section.

  In FIG. 12, “Null” indicates that the coordinate information is not associated with the attribute ID and the attribute type.

  In the attribute data portion 520, specific contents of attribute information, in this embodiment, the contents of comments as attribute information are recorded in association with attribute IDs.

  When the original navigation data 500 is generated, the guidance information generation process is terminated. For example, the generated guidance information may be stored in the external storage device 208 of the mobile terminal 200, or may be transferred to the map server 150 or the route search server 100 and stored in these servers.

・ Route guidance processing in original navigation mode:
FIG. 13 is a second diagram illustrating an example of the mode selection screen. FIG. 14 is a flowchart showing a processing routine of route guidance processing in the original navigation mode. FIG. 15 is a flowchart showing a route guidance processing routine using original navigation data. The route guidance processing in the original navigation mode (hereinafter also simply referred to as route guidance processing) is processing in which the main control unit 210 of the mobile terminal 200 performs route guidance according to the route guidance program M20.

  As shown in FIG. 13, when the user of the mobile terminal 200 selects the original navigation mode on the mode selection screen, the route guidance process is started. When the route guidance process is started, the route guidance program M20 acquires the original navigation data 500 as guidance information from the storage destination of the data (step S110). The acquired original navigation data 500 is stored in the buffer area BF of the internal storage device 212.

  Next, the current position information acquisition unit M21 of the route guidance program M20 controls the GPS receiver 201 to acquire current position information (step S120). The current position information is acquired as coordinate data on the ground coordinate space.

  When the current position information is acquired, the route guidance program M20 determines whether or not the current position is the start point of the original navigation data 500 (step S130). Specifically, the route guidance program M20 compares the start point information (FIG. 12: coordinate information (NS0, WE0) of the coordinate ID “0”) recorded in the original navigation data 500 with the current position information, When the distance between the current position and the start point is less than or equal to a predetermined value, it is determined that the current value is the start point.

  If it is determined that the current position is not the start point of the original navigation data 500 (step S130: NO), the route guidance program M20 performs normal route guidance from the current position to the start point of the original navigation data 500 (step S140). Specifically, the current location is set as the start location, the start location of the original navigation data 500 is set as the destination, and a request for generating recommended route data is transmitted to the route search server 100. In response to the generation request, the route search server 100 generates recommended route data and returns it to the mobile terminal 200. When the recommended route data is received, the route guidance program M20 of the portable terminal 200 transmits a map image data transmission request to the map server 150 by designating a necessary range. In response to the transmission request, the map server 150 returns map image data in the specified range to the mobile terminal 200. The route guidance program M20 of the portable terminal 200 performs route guidance using the acquired map image data and recommended route data.

  If it is determined that the current position is the start point of the original navigation data 500 (step S130: YES), the route guidance program M20 executes route guidance using the original navigation data 500 (step S150). If the user moves in advance to the starting point of the original navigation data 500 and then gives an instruction to select the original navigation mode, the above-described steps S110 to S140 can be omitted. The route guidance (step S150) using the data 500 may be executed.

  When the route guidance using the original navigation data 500 is started, the route guidance program M20 acquires a plurality of coordinate information (FIG. 12) recorded in the coordinate data portion 510 of the original navigation data 500 as guidance information ( Step S1501).

  The route guidance program M20 acquires necessary map image data according to the acquired plurality of coordinate information (step S1502). Specifically, the route guidance program M20 specifies a necessary range based on the acquired plurality of coordinate information, and transmits a map image data transmission request to the map server 150, whereby the map image data in the specified range is displayed. Is acquired from the map server 150. Note that this step may be omitted if necessary map image data has already been acquired when normal route guidance is performed up to the starting point of the original navigation data 500.

  When the map image data is acquired, the current position information acquisition unit M21 of the route guidance program M20 acquires current position information (step S1503). The route collation unit M22 of the route guidance program M20 collates a plurality of coordinate information acquired from the coordinate data unit 510 of the original navigation data 500 and the current position information, and corrects the current position (step S1504).

  FIG. 16 is a diagram for explaining the correction of the current position. FIG. 16 conceptually shows a traffic route (for example, a road) 301 drawn on the map image and a guidance route NR recorded on the original navigation data 500. The guide route NR is represented by connecting points corresponding to a plurality of coordinates recorded in the coordinate data portion 510 of the original navigation data 500 so that the order can be specified by line segments. FIG. 16 illustrates a portion expressed by points P10 to P15 which are a part of points corresponding to a plurality of coordinates in the guide route NR. Actually, the points P10 to P15 are finer intervals in order to improve the reproducibility of the trajectory input with the touch pen 230 in the above-described guidance information generation process, but in FIG. It is shown with an interval.

  In this embodiment, since the guide route NR is created by handwritten input by the user, as shown in FIG. 16, the traffic route 301 intended as the route and the guide route NR may not exactly overlap. In this case, the current position represented by the current position information acquired using the GPS receiver 201 is considered to be located in the vicinity of the traffic route 301 away from the guide route NR. In FIG. 16, white circles PR <b> 1 to PR <b> 5 indicate points corresponding to the current position information acquired using the GPS receiver 201 in the course of route guidance using the original navigation data 500.

  In step S1504, the route matching unit M22 corrects the current position to the intersection of the perpendicular drawn from the point corresponding to the current position information acquired using the GPS receiver 201 with respect to the guide route NR and the guide route NR. Set. In FIG. 16, black circles AP <b> 1 to AP <b> 5 indicate corrected points corresponding to the points PR <b> 1 to PR <b> 5 represented by the current position information acquired using the GPS receiver 201.

  The guidance execution unit M23 of the route guidance program M20 superimposes and displays the map image, the guidance route, and the corrected current position on the display panel 202 (step S1505).

  FIG. 17 is a first diagram illustrating an example of a screen displayed in route guidance using the original navigation data 500. As shown in FIG. 17, in route guidance using the original navigation data 500, the mark 303 representing the current position is not a point 302 where the user and the mobile terminal 200 actually exist, but a line image 304 representing the guidance route NR. Displayed above. This is because the current position correction process executed in the previous step S1504. This correction prevents the line image 304 representing the guidance route NR displayed on the route guidance screen from being separated from the mark 303 representing the current position, thereby reducing the user's uncomfortable feeling. For example, the guidance execution unit M23 displays the displayed mark 303 (corresponding to the coordinates of the current position after correction) and the point 302 (corresponding to the coordinates of the current position before correction) where the user and the mobile terminal 200 actually exist. The map image is displayed so that the intermediate point is located at the center of the display panel 202 in the left-right direction.

  Next, the guidance execution unit M23 determines whether or not the corrected current value is an attribute information display update point (step S1506). The attribute information display update point is a point where the display of the comment as the attribute information on the display panel 202 is updated. Specifically, the attribute information is newly displayed from the state where the attribute information is not displayed on the display panel 202. And a point where the display of the attribute information is deleted from a state where the attribute information is already displayed on the display panel 202 or a point where another attribute information is displayed. Specifically, the guidance execution unit M23, among a plurality of coordinate information recorded in the coordinate data unit 510 of the original navigation data 500, the current position (coordinate) after correction and the closest coordinate information (nearest coordinate information) ) Is associated with the attribute ID and the attribute type, it is determined whether or not it is an attribute information display update point. For example, when the attribute ID and the attribute type “P” or “S” are associated with the closest coordinate information, it is recognized that this is a point where the attribute information is newly displayed. Further, when the attribute ID and the attribute type “E” are associated with the closest coordinate information, it is recognized that the point is the point where the display of the attribute information being displayed is deleted. Further, when displaying the attribute information associated with the point, the guidance execution unit M23 has passed a predetermined time (for example, 20 seconds) from the start of display, or a predetermined distance from the display start point. It is good also as judging whether it is an attribute information display update point by having progressed only.

  When the guidance execution unit M23 determines that the current position is the attribute information display update point (step S: YES), the display of the comment as the attribute information is updated according to the update mode (display deletion / display start / display change). (Step S1507).

  FIG. 18 is a second diagram illustrating an example of a screen displayed in route guidance using the original navigation data 500. FIG. 18 shows a state where a comment 305 as attribute information is displayed on the route guidance screen.

  When the guidance execution unit M23 determines that the current position is not the attribute information display update point (step S: NO), or after updating the display of attribute information, the current position is the end of the route guidance using the original navigation data 500. It is determined whether or not the point has been reached (step S1508). The route guidance end point is a point corresponding to the last coordinate information in the order among the plurality of coordinate information recorded in the coordinate data portion 510 of the original navigation data 500. In this embodiment, the coordinate information (NSn, WEn) of the identification ID “n” recorded in the coordinate data portion 510 of the original navigation data 500 represents the end point.

  If the guidance execution unit M23 determines that the current position has not yet reached the end point (step S1508: NO), the process returns to step S1503. In this way, the route guidance program M20 repeats the processing of steps S1503 to S1507 described above, whereby the route guidance screen displayed on the display panel 202 is sequentially updated, and the route guidance using the original navigation data 500 is advanced.

  When the guidance execution unit M23 determines that the current position has reached the end point (step S1508: YES), the route guidance using the original navigation data 500 is terminated.

  According to the present embodiment described above, the user can easily generate the original navigation data 500 for realizing his / her favorite route guidance.

  In addition, the user can use the original navigation data 500 to use favorite route guidance that is rich in flexibility and fulfillment.

  For example, in this embodiment, the trajectory drawn by the touch pen 230 is recognized and used as it is as the guide route NR, so that a highly flexible guide route NR can be constructed depending on the user's idea. Specifically, a route that passes through the same point or route as shown in FIG. 11 a plurality of times can be easily specified as a guide route. It is also free to insert a route via a stopover location or a comment about the stopover location.

  FIG. 19 is a diagram illustrating an example of a highly flexible guide route. The user can devise an original device when creating the guide route NR through the difficult-to-understand traffic route. For example, in a three-way road as shown in FIG. 19A, a guide route NR having a portion 308 that is intentionally provided with an acute angle on the left side may be drawn to clearly show that the route passes through the leftmost route. Then, as shown in FIG. 19B, an easy-to-understand display is easily realized at the time of route guidance. Furthermore, as shown in FIG. 19B, it is also easy to display a combination of comments 305 pointing out the difficulty of understanding, so that route guidance with high flexibility and fulfillment can be easily realized.

  Further, in route guidance using the original navigation data 500, route data and attribute information prepared in advance need not be used. As a result, for example, for a route passing through an area where route data or attribute information is not sufficient, such as in a foreign country or a local area, a satisfactory route guidance can be easily realized.

  Further, conventionally, only guidance using route data prepared in advance and attribute information associated with the route data has been possible. For this reason, only the same attribute information can be used for guidance at the same point. In the present embodiment, for example, in the original navigation data 500, coordinate information is recorded in such a manner that the order can be specified. Therefore, even coordinate information representing the same coordinate is recognized as different coordinate information if the order is different (in the embodiment, the identification ID is different). As a result, as shown in FIG. 11, when a route that passes through the same point or route a plurality of times is created, different attribute information (for example, comments) is passed between the first time and the second time. Can be displayed.

B. Second embodiment:
In the first embodiment, the mobile terminal 200 has a function as a guidance information generation device that generates the original navigation data 500 and a function as a route guidance device that uses the original navigation data 500. Instead of this, different devices may have a function as a guidance information generation device and a function as a route guidance device. An example of such an embodiment will be described as a second embodiment with reference to FIGS.

  FIG. 20 is an explanatory diagram showing a schematic configuration of a map display system 10b as the second embodiment. FIG. 21 is a flowchart showing a processing routine of guidance information generation processing in the second embodiment. FIG. 22 is a diagram for explaining the release of the original navigation data.

  As shown in FIG. 20, the map display system 10b as the second embodiment includes a route search server 100, a map server 150b, a base station BS, a mobile terminal 200b, and a personal computer 400.

  The map server 150b of the second embodiment has a guide information generation program M10 stored in its memory in addition to the configuration of the map server 150 of the first embodiment. That is, in the second embodiment, the map server 150b functions as a guidance information generating device. Since the other structure of the map server 150b of 2nd Example is the same as that of the map server 150 of 1st Example, detailed description is abbreviate | omitted.

  The personal computer 400 is a known computer and includes a CPU, a ROM, and a RAM (not shown) and is connected to the Internet INT. The personal computer 400 includes a display device 402, a mouse 430, and a keyboard 406. A well-known browser program M30 is stored in an internal storage device such as a ROM or a RAM of the personal computer 400. The personal computer 400 can use the function of the map server 150 as a guidance information generation device by accessing the map server 150b using the browser program M30. That is, the map server 150 functions as an application server device that provides the accessible client device with the function of the guidance information generation program M10.

  The mobile terminal 200b of the second embodiment stores a route guidance program M20 and functions as a route guidance device, but does not store a guidance information generation program M10. For this reason, the portable terminal 200b may not have a function for inputting a route route such as a touch panel. Since the function of the mobile terminal 200b of the second embodiment as a route guidance device is the same as that of the mobile terminal 200 of the first embodiment, detailed description thereof is omitted.

  Guide information generation processing as a service provided by the map server 150b to the personal computer 400 as a client device will be described with reference to FIG. Of the processes shown in FIG. 21, the processes up to steps S10 to S60 are basically the same as the processes up to steps S10 to 60 having the same reference numerals in the guidance information generating process of the first embodiment described with reference to FIG. Since it is the same, detailed description is omitted. However, the screen presented to the user is displayed on the display device 402 of the personal computer 400, and input by the user is performed by input means provided in the personal computer 400, and information such as generation of guidance information according to the input is provided. The process is executed in the map server 150b. The input of the route locus by the user is not limited to the touch pen and the mouse, and is performed by various means provided in the client device. The path trajectory may be input using various pointing devices such as a trackball and a touch pad, or the path trajectory may be input using a touch panel that accepts an input of tracing the display screen with a finger.

  The guidance information generation process in the second embodiment may be completed by step S60 as in the first embodiment, but in response to the user's request, the process starting from step S70 in FIG. Processing for disclosing the original navigation data 500 as the guidance information may be performed. Specifically, when the user requests the disclosure of the original navigation data 500, the guidance information generation program M10 of the map server 150b publishes the original navigation data 500 on the Internet INT.

  As shown in FIG. 22, the guidance information generation program M10 publishes the original navigation data 500 by associating the link embedded in the published WEB page with the generated original navigation data 500 (step S70). In the WEB page WP shown in FIG. 22, a route display button is displayed as a link for accessing the original navigation data 500 together with the introduction text of the published original navigation data 500. When another user accesses the original navigation data 500 as the guidance information via the WEB page WP (step S80: YES), the guidance information generation program M10 of the map server 150b reads the map image and guidance based on the original navigation data 500. Display data for displaying the route is transmitted to the accessing user (step S90). As a result, the other user's browser that has been accessed displays the attribute information and point / section acceptance screen as shown in FIG. 11 described in the first embodiment.

  And the guidance information generation program M10 of the map server 150b provides the service which performs the process of step S30-S50 mentioned above with respect to the other user who accessed. As a result, the accessing user can update the original navigation data 500 by adding a comment as attribute information to the published original navigation data 500.

  When the user who disclosed the original navigation data 500 performs route guidance using the original navigation data 500, the user downloads the original navigation data 500 from the map server 150b to the portable terminal 200b. The route guidance program M20 of the portable terminal 200b performs route guidance (FIGS. 13 to 18) in the first embodiment using the downloaded original navigation data 500.

  According to the second embodiment described above, the following effects can be obtained in addition to the same effects as the first embodiment. That is, comments as attribute information are added to the original navigation data 500 not only by the user as the original author of the original navigation data 500 but also by other users. As a result, when the original author performs route guidance using the original navigation data 500, unknown attribute information is displayed. As a result, the route guidance can be provided further and new enjoyment can be provided to the user. For example, if the theme is determined and the original navigation data 500 is made public, attribute information corresponding to the theme can be collected from other users. Examples of themes include “gourmet”, “shopping”, and “one person traveling”.

C. Variations:
・ First modification:
In the first embodiment and the second embodiment, comments (text data) are used as attribute information related to points or sections on the guide route NR. However, the attribute information is not limited to this, and various information is available. Can be used. Specifically, still image data, moving image data, audio data, and the like are used as attribute information. As these data, data created by the user himself / herself may be used, or data provided as a library from the map server 150b, the route search server 100, or another server may be used.

  For example, as audio data, a music file in which a user's favorite music is recorded may be associated with a point or section on the guide route NR. The music file may be recorded in the original navigation data 500. Further, the file may be stored as a separate file in the external storage device 208 of the portable terminal 200, or may be stored in a device such as a server or a portable player that is connected to the portable terminal 200 so as to be capable of wired or wireless communication. In such a case, in the original navigation data 500, only a pointer representing the music file is recorded in association with a point or section on the guidance route NR, and the portable terminal 200 performs a music file as needed during the course guidance process. Just get it.

  In addition, as attribute information regarding a section, information indicating the type of road in the section, for example, information indicating a highway, a national road, a prefectural road, a sidewalk, etc., information indicating a user's means of transportation, For example, information representing a private car, a train, a walk, a taxi, a bus, or the like may be used.

・ Second modification:
In the first and second embodiments, the guide route NR is input by drawing a route locus on the map image displayed on the display panel 202 using the touch pen 230. The input mode of the route NR is not limited to this. For example, in the first example, the guidance information generation program M10 of the mobile terminal 200 of the first example may further include a movement locus acquisition unit M15 (not shown) as a submodule. The movement locus acquisition unit M15 generates movement locus data in response to a user request. The movement locus data is data in which the movement locus of the mobile terminal 200, that is, the movement locus of the user carrying the mobile terminal 200 is recorded.

  Specifically, when the user instructs generation of movement trajectory data, the movement trajectory acquisition unit M15 uses the GPS receiver 201 to obtain current position information (for example, coordinate information in the ground coordinate space) at predetermined intervals. The data are sequentially acquired and stored in the buffer area BF in such a manner that the acquired order can be specified. The movement locus acquisition unit M15 ends the acquisition of the current position information when the user instructs the end of the generation of movement locus data. The movement trajectory acquisition unit M15 generates a movement trajectory file in which a plurality of coordinate information as a history of the current position information stored in the buffer area BF is recorded in a manner in which the acquisition order can be specified, and stores the movement trajectory file in the external storage device 208. .

  In this modification, the route trajectory receiving unit M11 of the guidance information generating program M10 records the moving trajectory file by reading the moving trajectory file described above, instead of steps S10 and S20 (FIG. 4) of the first embodiment. The movement trajectory of the user is acquired as a route trajectory. Specifically, the path trajectory accepting unit M11 accepts the designation of the movement trajectory file from the user, and specifies the plurality of coordinate information recorded in the movement trajectory file in a manner in which the acquisition order can be identified, and the acquisition order is directly specified. Read as possible. By doing so, the route trajectory receiving unit M11 acquires a plurality of coordinate information corresponding to a plurality of points on the movement trajectory as information indicating the guidance route. In this modification, a plurality of coordinate information acquired in this way is used as a guide route as it is. Since the processing after step S30 is the same as that of the first embodiment, detailed description thereof is omitted.

  According to this modified example described above, the guide route is specified using the user's movement trajectory data, so the burden on the user for generating the original navigation data 500 is reduced. In this modified example, for example, a user generates original navigation data 500 to which a route driven by the user is used as a guide route and comments such as impressions are given as attribute information, and the original navigation data 500 is sent to others. It is convenient when you publish on your blog and use it for others.

  Of the functions of the guidance information generation program M10 in this modification, the movement trajectory acquisition unit M15 and the other functional units M11 to M14 may be stored in different devices. For example, the movement locus acquisition unit M15 may be stored in a portable terminal or a car navigation device, and the other functional units M11 to M14 may be stored in a personal computer. In this case, the user moves the movement trajectory data generated by the portable terminal or the car navigation device to a personal computer via a memory card or a wired or wireless network, and finally uses the personal computer. The original navigation data 500 may be generated. In this case, in the movement trajectory acquisition unit M15, the portable terminal or the car navigation device and the personal computer constitute one guidance information generation device.

・ Third modification:
In the first and second embodiments, the comment as the attribute information is used to be displayed on the display panel 202 at the time of route guidance. However, the use mode of the attribute information at the time of route guidance is limited to this. I can't. For example, when information representing the user's transportation means is used as the attribute information, the attribute information may be used to change the route guidance mode according to the transportation means at the time of route guidance. For example, it is conceivable to change the scale of the map image according to the transportation means.

-Fourth modification:
The function as the guidance information generating device is not only realized by a single device (the mobile terminal 200 in the first embodiment, but the map server 150b in the second embodiment), but may be realized by a plurality of devices. For example, the route trajectory receiving unit M11, the section designation receiving unit M12, and the attribute information receiving unit M13 among the submodules of the guide information generating program M10 that realizes the function as the guide information generating device are portable terminals owned by the user. Or it may be installed in a personal computer, and the guidance information generation part M14 may be installed in a provider's server. And a user produces | generates the information showing guidance route NR, the information showing the designated point or area on guidance route NR, and attribute information with a terminal or a personal computer, and uploads to a server. The server generates original navigation data using each uploaded information and provides it to the user. In such a case, the user's portable terminal or personal computer and the operator's server function as one guide information device.

  Similarly, the function as a route guidance device may be realized not only by a single device but also by a plurality of devices.

-5th modification:
The original navigation data 500 in the first embodiment and the second embodiment includes a coordinate data portion 510 and an attribute data portion 520, but the aspect of the original navigation data 500 is not limited to this. For example, necessary map image data (vector data or raster data) may be further added to the original navigation data 500. In this way, when performing route guidance using the original navigation data 500, the route guidance device does not need to acquire map image data from the outside (for example, the map server 150), reducing communication load, Communication costs can be reduced. In addition, the original navigation data may be stored separately in the coordinate data part 510 and the attribute data part 520. For example, in the route guidance process (FIGS. 14 to z8) in the first embodiment, only the coordinate data unit 510 may be stored in the mobile terminal 200, and the attribute data unit 520 may be stored in the map server 150b. In this case, the mobile terminal 200 performs route guidance using the coordinate data unit 510, and acquires necessary attribute information recorded in the attribute data unit 520 from the map server 150b when the attribute information display update point is reached. It's also good.

-6th modification:
The first and second embodiments are relatively large systems using the Internet INT or the like, but are not limited thereto. For example, the map image data and the guidance information generation program M10 may be installed in the personal computer 400, and the guidance information may be generated by the personal computer 400 alone. The generated guidance information may be transferred to a portable terminal or a car-mounted car navigation device in which the route guidance program M20 is installed through various memory cards to perform route guidance.

-Seventh modification:
In the first and second embodiments described above, the current position is determined by the GPS receiver 201 alone. However, the positioning of the current position may be performed using, for example, the GPS receiver 201 together with a vehicle speed sensor or an acceleration sensor.

-Eighth modification:
The form of the original navigation data is not limited to the original navigation data 500 shown in FIG. 12, and can be modified into various forms. For example, the plurality of pieces of coordinate information may be recorded in such a manner that the order can be specified. For example, the plurality of coordinate information may be recorded in the form of link information representing a link connecting adjacent coordinate information, and an identifier may be attached so that the order of each link can be specified. Moreover, the attribute information should just be recorded in the aspect which can specify the point or area on the path | route represented by several coordinate information, for example, may be linked | related with the above-mentioned link information.

-Ninth modification:
In the first embodiment, the creator of the guidance information (original navigation data 500) and the person who enjoys the route guidance using the guidance information are the same, but they may be different persons. For example, the creator of the guide information may attach the guide information to an email and send it to another person, and the other person who receives the transmission may enjoy the route guidance using the guide information. In addition, the creator of the guide information may make the guide information public on his blog or the like and freely downloadable for use by others.

  Further, as will be understood from the second embodiment, the user who performs a part of the process of creating the guide information (original navigation data 500) may be different from the user who performs the other part. As in the second embodiment, the person who inputs the route trajectory may be different from the person who inputs the attribute information. Further, one user may input a part of the route locus, and another user may input a route locus that follows the route locus.

-10th modification:
In the above embodiment, the input route trajectory is used as it is as a guide route without correction, but the route trajectory may be corrected and the corrected route may be used as the guide route. In this case, a plurality of coordinate information representing the corrected guide route is recorded in the original navigation data 500. The correction may be performed by, for example, well-known smoothing, or may be performed by matching the route to the road drawn on the map image with the route data stored in the route search server 100. .
