  In S121, the map display determination unit 24 determines a place for displaying the character string of the station name information and the transfer information from the coordinates of the railway line intersecting with the end of the display area of the map image acquired in S106, and from the length of the character string The area (display area size) necessary for displaying the station name information and transfer information is determined, and the process proceeds to S122.

  In S122, the display place name determination unit 28 displays the name of the station to which the track is connected, superimposed on the display area of the map image selected by the map display determination unit 24. Finally, in S123, the determination unit 10 changes the display range and display contents of the map image based on the movement of the user who has the navigation device 1 or the input instruction from the operation unit (not shown) by the user. The processing returns to S101 and repeats the calculation and display processing again. With the above procedure, a series of processes for displaying the names of stations connected outside the display area of the map image is completed.

  Next, with reference to FIG. 4, the flow of processing for determining whether or not the navigation device 1 possessed by the user is on board in S108 and S109 of the flowchart of FIG. 3 will be described. When the process is started, in S201, the latitude / longitude determination unit 22 acquires position information from the position sensor 32 of the sensor unit 30 using a position information acquisition system such as GPS.

  In S202, the movement determination unit 14 determines the rotation and altitude of the navigation device 1 possessed by the user from the direction sensor 34 of the sensor unit 30 including a geomagnetic sensor, an acceleration sensor, an altitude sensor, and the like. Get information.

  In S <b> 203, the boarding determination unit 12 determines whether the current location of the user who has the navigation device 1 matches any of the stations registered in the station vector DB 46 of the map information storage unit 40. If the user's current location is a station (YES in S203), the process proceeds to S208. If the user's current location is not a station (NO in S203), the process proceeds to S204.

  In S <b> 204, the boarding determination unit 12 determines whether or not the navigation device 1 possessed by the user is moving along the track vector data stored in the track DB 44 of the map information storage unit 40. When moving along the track (YES in S204), the process proceeds to S205. If not moving along the track (NO in S204), the process proceeds to S213.

  In S205, the destination determination unit 20 uses the position information acquired by the position sensor 32 and the vector data of the track stored in the track DB 44 to determine the route on which the train on which the user carrying the navigation device 1 is traveling is running. Specify vector data.

  In S206, the destination determination unit 20 follows the track indicated by the vector data in the direction opposite to the direction in which the user carrying the navigation device 1 is traveling, and sets the connection destination of the opposite track. Determine the station that exists.

  If the station existing at the connection destination can be searched, the destination determination unit 20 detects the timetable information of the destination station from the timetable DB 52 of the train information storage unit 50, and refers to the current time acquired by the time determination unit 16. The train of the train on which the user is boarding, the type of the train (for example, high-speed train, ordinary train, etc.), destination information, stop station information, etc. The train information is listed, and the output control unit 60 outputs the train information superimposed on the map image.

  The train information is associated with, for example, “11:30 Koriyama station, ordinary train for Nara, no stop on the way”, and a plurality of train candidates are listed and output. The user determines the train on which he / she is riding by selecting and selecting the train he / she is on from the list which is output, and inputs it to the navigation device 1.

  In addition, about the train information of the train which is the operation which does not stop at the station immediately before by searching not only the station where the train which the user who has the navigation apparatus 1 boarded just passed but also the previous station You may get it.

  In S207, the boarding determination unit 12 determines the timetable of the train on which the user who has the navigation device 1 is currently traveling from the item selected by the user from the list acquired and displayed in S206, and saves the train information. To do. The process proceeds to S121.

  In S208, the boarding determination part 12 acquires the timetable information of the said station with reference to timetable DB52 matched with the station information of the station which is a user's present location which has the navigation apparatus 1 determined in S203. .

  In S209, the boarding determination unit 12 compares the track DB 44 of the map information storage unit 40 with the current position information acquired in S201, and adds the current position information to the track vector data stored in the track DB 44. It is judged whether it is moving along. If the position information is moving along the track vector data (YES in S209), the process proceeds to S210. If the position information has not moved along the track vector data (NO in S209), the process proceeds to S213.

  In S <b> 210, the boarding determination unit 12 determines whether the train on which the user who has the navigation device 1 has started moving from the station at the time according to the timetable acquired from the timetable DB 52. If movement from the station has started according to the timetable (YES in S210), the process proceeds to S211. If the movement has not started from the station according to the timetable (NO in S210), the process proceeds to S213.

  In S211, the display place name determination unit 28 acquires train information such as information on the destination of the train on which the user carrying the navigation device 1 rides and information indicating the type of train from the timetable information acquired in S208. To do.

  In S212, the boarding determination unit 12 determines that the navigation device 1 possessed by the user is riding, and ends the series of processes. In S212, the boarding determination unit 12 determines that the navigation device 1 possessed by the user is not on the train, and ends the series of processes.

  Next, the contents of the station vector data stored in the station vector DB 46 of the map information storage unit 40 will be described with reference to FIG. FIG. 5 is a list showing an example of the data structure of the station vector data.

  In the database, there is a track DB 44 in which information on only tracks is collected separately from the map DB 42 for displaying a map on the screen. The track DB 44 has a configuration in which position information (longitude and latitude) where a track is actually laid on a map is associated with vector data. That is, the track vector data is associated with longitude and latitude, respectively, and the station vector data is associated with longitude and latitude, respectively.

  In addition, the station vector data contains vector data indicating the shape of the station on the map image. As shown below, “latitude, longitude”, “station name”, “train information to stop”, “transfer” Information (route name information that can be transferred) "," station timetable information and the destination of each train, type of train (normal, high speed, etc.) "," name of the line connected to the station " Information is associated with each station vector data.

  As a specific example, when “station vector data A” is vector data indicating “JR Nara station”, “135 ° 81′89.10 ″, 34 ° 68′04.05 as“ latitude and longitude ”. ””, “Station name” is “Nara Station”, “Stop train information” is “Rapid Express, Express, Semi Express, Section Semi Express, Normal”, “Transfer Information” is “Kintetsu Nara Line”, “Station Timetable Information And the destination and type of train ”is“ Kyoto, Oji, Tenri, Miyako Rapid, Rapid, Section Rapid, Normal ”, etc. The information “line” is associated with the station vector data.

  Further, when the “station vector data B” is vector data indicating “Kintetsu Shin-Omiya Station”, “135 ° 81′05.85 ″, 34 ° 68′53.63 ″”, “ “Shin-Omiya Station” as “Station Name”, “National Express for Nara, Normal for Kyoto, Semi Express for Namba”, “Transfer Information” is “None”, “Station Timetable Information and Destination, Train Information” The station vector data is the information that the name of the connected line is “Kintetsu Nara Line”, such as “Type” is “Nara, Namba, Kyoto, Rapid Express, Express, Semi Express, Section Semi Express, Normal”. It is associated. It is assumed that similar data exists for all stations.

  It should be noted that the information on “stations to stop” and “connected route names” may be collectively managed as information on “train types”. Specific examples include, for example, “Station information” and “Connected route name” based on the “train type” information such as “Connect to Tenri via Yamato-Saidaiji, Rapid express bound for Kyoto”. It may be used.

  Next, the contents of data stored in the map DB 42, the track DB 44, and the station vector DB 46 of the map information storage unit 40 will be described with reference to FIG. FIG. 6A shows the contents stored in the map DB 42 in which the map image used for the screen display is recorded, and FIG. 6B shows the track and station vector data used for the screen display. It is a figure which shows an example of the content memorize | stored in track DB44 and station vector DB46.

  In Fig.6 (a), the information of a road, a track, a station name, and a place name is shown as a map image. Although the details are described here in a simplified manner, the map DB 42 may store road names, rivers, river names, buildings, landmarks, altitudes, contour lines, administrative districts, and other map information. Good.

  In FIG. 6A, the Kintetsu line and “Shin-Omiya” station are shown in the horizontal direction at the top of the figure, and the JR Nara line and “Nara” station are shown in the vertical direction in the center of the figure. In addition, each road and city name is shown.

  FIG. 6B shows the vector data of the track and the station corresponding to FIG. As in FIG. 6 (a), the Kintetsu Line track and "Shin Omiya" station are shown in the horizontal direction at the top of the figure, and the JR Nara Line track and "Nara" station are shown in the vertical direction in the center of the figure. . In addition, each road and city name is shown. Since the track and station vector data is stored in the form of vector data, it is easy to calculate the intersection by calculation.

  Next, with reference to FIG. 7, a description will be given of a method in which the destination determination unit 20 of the navigation device 1 of the present embodiment determines a connection destination that exists outside the display range of the map image. FIG. 7A is a diagram showing a display area of a map image and a connection destination of a track, and FIG. 7B is a diagram showing a station name existing at the end of the track.

  When determining the station name to be displayed, the display location name determination unit 28 first acquires information indicating the current location from the sensor unit 30. Next, the map display determination unit 24 cuts out a map area to be displayed in accordance with the scale setting from the map DB 42 and generates a map image. Further, the map display determination unit 24 acquires information on the latitude and longitude corresponding to each side of the outer periphery, which is the outermost side of the display range, and in the track DB 44, the station and the longitude on the latitude and longitude of each side of the acquired outer periphery are obtained. It is judged whether the vector data of the track does not intersect.

  In Fig.7 (a), the small rectangular area | region in the center part of a figure corresponds to the display area of a map image. In addition, a portion where a small rectangular area in the center of the figure intersects with the vector data of the track is surrounded by a circular dotted line. The destination determination unit 20 collates the vector data indicated by each side of the rectangular area and the vector data of the line, and detects a location that intersects the rectangular area.

  In FIG. 7B, after detecting a point where the vector data indicating the outer periphery of the display area and the vector data of the line intersect, the destination determination unit 20 searches for a station connected to the line that exists outside the display area. To do.

  The destination determination unit 20 searches the vector from the position where the vector data intersects in the direction not to be displayed, which is not included in the map display area, and the station name of the station that has arrived next. Get information about. In FIG. 7B, the name of “Hirajoyama” station in the upward direction, “Yamatoseidaiji” station in the left direction, and “Yamatokoriyama” station and “Obari” station in the downward direction are acquired by the search.

  Next, with reference to FIG. 8, the latitude and longitude search method performed when the navigation apparatus 1 of this embodiment determines the position for displaying the name of the connection destination station will be described. FIG. 8 shows vector data of tracks and stations indicating the same range as the display area of the map image shown in FIGS. 6 and 7.

  The display place name determination unit 28 has a latitude “30 ° 41′14.79 ″” and a longitude “135 ° 48′04.09 ″” in the coordinates corresponding to the upper left of the display area of the map image. 14.79 seconds ”, longitude“ 135 ° 49′29.73 ″ ”, downward latitude“ 34 ° 40′19.46 ″ ”, longitude“ 135 ° 48′04.09 ″ ” Judgment is made on the intersection of vector data while moving latitude and longitude.

  Similarly, from the latitude “34 ° 40′19.46 ″” and the longitude “135 ° 49′29.73 °” corresponding to the lower right of the display area of the map image, the upward latitude “30 ° 41 minutes 14. 79 seconds ”, longitude“ 135 ° 49′29.73 ″ ”, leftward“ 34 ° 40′19.46 ″ ”, longitude“ 135 ° 48′04.09 ″ ”, latitude and longitude The vector data is crossed while moving.

  By this scanning, the display place name determination unit 28 acquires the latitude and longitude information of the point where the vector data of the station and the track intersects the vector data indicated by the frame line of the display area of the map image.

  Next, referring to FIG. 9, from the information on the intersection of the vector data acquired by the scanning process of FIG. 8, the name of the connected station existing outside the map image display area is displayed in the map image display area. A method for determining the display position will be described. FIG. 9 is a diagram for explaining a method for determining the display position of the station name of the connection destination in the navigation device 1 of the present embodiment. FIG. 9A shows a display area of the station name to be displayed, and FIG. It shows how to determine the display position of the station name.

  In FIG. 9 (a), the station name obtained by the scan process of FIG. 8 is added with the character string “To” and the area to be displayed is calculated from the set character points, and the center point in the character string display area is calculated. Get the coordinates of. The station name is shown on the left side of FIG. 9A, and the size of the display area and the coordinates of the center point corresponding to the length of the character string of the station name are shown on the right side.

  In FIG. 9B, the line vector data and the frame line vector data indicating the display area of the map image are connected to positions shifted downward, rightward, leftward, and upward. It shows a method of displaying a character string indicating the previous station name. The display place name determination unit 28 shifts the center point of the display area from the latitude / longitude information acquired in the scan of FIG. 8 to the position where the display area of the character can be displayed, and displays the position where the character string indicating the connected station name is displayed. decide.

  FIG. 10 uses the processes of FIGS. 7 to 9 described above to search for connection destinations of tracks that exist outside the display range of the map image, determine the display area of the station name, and display it superimposed on the map image. It is a figure which shows a screen display. In the screen display of FIG. 10, each track and display are shown for “Hirashiroyama” station, “Yamatoseidaiji” station, “Kintetsu Nara” station, “Yamatokoriyama” station, and “Obiso” station existing at the end of the track. The character strings `` Supirajo Shiroyama '', `` Saito Yamato Seidaiji '', `` Shin Kintetsu Nara '', `` Saito Yamato Koriyama '', and `` Shiso Koriyama '' are placed at a position that is a predetermined distance away from the point where the area frames intersect. By displaying, the map image is presented in an easy-to-understand state to the user by associating the track and the connected station name.

  In addition, in the display area of the map image shown in FIG. 10, when the navigation device 1 possessed by the user moves and moves downward, the station names of the tracks divided into two branches may overlap. In this case, as shown in FIGS. 11A to 11C, when the display positions of the character strings indicating the station names are close to each other, the display areas of the character strings are shifted and displayed so as not to overlap. .

  In this way, when the current position of the user who possesses the navigation device 1 changes, the correct map image display area corresponding to the current position is always updated by repeating the same processing as described above.

  FIG. 12 is a diagram showing a state where the display screen is updated when the user who has the navigation device 1 moves to the upper side (north side) of the screen from the state of the map image display screen shown in FIGS. 7 to 10. It is.

  In the above description, the station name of the station that is outside the map image display area and is the connection destination of the latest track is displayed, but the present invention is not limited to this. If the scale of the map is changed and a wide scale is displayed, the next station may not be displayed, but the name of a large station may be displayed so that the general direction of the destination of the train can be understood. .

  FIG. 13 and FIG. 14 are diagrams illustrating an example of a method for displaying a station name when a map scale is changed and a wide scale display is performed.

  In FIG. 13, not only the nearest station outside the frame line indicating the display area of the map image but also a station ahead is searched. In this case, the track DB 44 includes information indicating at what scale the display should not be performed as incidental information of each station. When the display station name shown in FIG. 7 is acquired using this display setting information, when information indicating “not displayed” at a specific scale is found in the accompanying information of the station in the process of searching for the station name. Searches for the station name until the information “display” is found.

  To give a specific example, in the station name search process of FIG. 7, if the display setting of the next station is set to “not display” at the scale of “1/50000”, the search is further advanced to the next station. Thereafter, the search is repeated until a station that is “displayed” at a scale corresponding to the display setting of the station ahead is found.

  FIG. 14 is a diagram showing a case where a station name is displayed by the search method shown in FIG. A wide range is shown in a larger scale than the map images shown in FIGS. 7 to 10, and not the name of the nearest station as the connection destination of the track, but “Kyoto”, “Kyoto Tanabe City”, “Kyokyo Bridge”, It displays large terminal stations corresponding to express stops, such as “Nishi-Namba”, “Shin-Oji”, “Shisuhara City”, “Shi Sakurai”, and “Shigameyama”.

  Next, still another display method will be described with reference to FIGS. 15 and 16.

  FIG. 15A is a diagram illustrating an example of displaying, in addition to a station name, a train line that can be changed or connected as information indicating a connection destination of a track. In this case, the track DB 44 includes information indicating a transfer line as incidental information of each station. This supplementary information is referred to when searching for the station name in the search process of FIG. 7 described above, and is referred to when displaying the information of the transfer line when the user has set to display the information of the transfer line.

  FIG. 15B is a diagram showing an example in which a station name in the traveling direction of the train on which the user who owns the navigation device 1 is riding is displayed large and a station name in the direction opposite to the traveling direction is displayed small. It is. In this case, the user who owns the navigation device 1 is currently on a train, determines which train is on board, detects information indicating which direction the train is heading, and a map image. Superimposed on the display.

  At this time, (1) When boarding a train, you must always go through the station. (2) If you can obtain location information with GPS or other information and confirm that you have arrived at the station, Call timetable information, (3) Create a list of trains that depart from the current time, (4) When position information starts moving along the track, there is a train that departs at that time (5) If there is a match, it is assumed that the train is on the train and the next information is acquired, and the boarding decision is made.

  At this time, destination information indicating the destination of the train, stop station information indicating the stop station, information indicating the type of train, and the like are also acquired as train information from the timetable information indicating the timetable. Note that if there is no timetable information that matches the train's location information and current time information, the user is assumed not to be on the train and to move on foot or by car. Also good.

  With the above procedure, it is possible to change and display the size of characters for displaying the station names of the next station and the past station. This is effective when displaying a north-up display instead of a head-up, and the display can be easily understood by the user.

  FIG. 16A is an example of a display method when it is determined that the navigation device 1 possessed by the user is not on the train. In FIG. 16A, the location indicated by ◯ in the figure corresponds to the current location of the user, and the user gets on the car and moves downward along the central road.

  In this case, “To Maibara” and “To Kyoto” are displayed as connection destinations of the track running in the upper left of FIG. 16, but they are displayed in small letters. When it is possible to determine that the user is moving by a method other than a train such as a car or walking, the display of the character string indicating the connection destination of the track may be reduced or may not be displayed.

  FIG. 16B is an example of a display method in a case where a train on board is discriminated and a character string indicating a stop station is displayed as connection destination information. In FIG. 16B, by referring to the information of the timetable, the type of train currently on board such as “normal” or “rapid” is discriminated, and the name of the station where the train stops is displayed. . Also, the station names of other trains on routes that are not on board are displayed in a small size.

  In FIG. 16B, the line running up and down the left side of the figure is the “Nankai Takano Line”, and the line running from the upper left to the lower right of the figure is the “Osaka Loop Line”. Currently, the user takes the “Yamatoji Rapid” train on the “Osaka Loop Line” and moves to “Osaka” (the place marked with a circle).

  In this case, “Bentencho”, which is the next stop station of “Yamatoji Rapid”, and “Shin-Imamiya”, which is the previous stop station, are displayed as connection information. In addition, the station information of “Nankai Koya Line”, which is a route on which the user is not on, “Shiomi Bridge” and “Shi Kizu” are displayed in a small size.

  As described above, in the navigation device 1 according to the present embodiment, for the track currently displayed on the screen, the number of stations connected to the end of the track that is no longer displayed on the screen is detected. The station name of the connection destination is displayed on the end of the displayed track. This process is always performed when the map on the screen is rewritten as the navigation device 1 moves, so that the name of the next station to which the navigation device 1 is heading can be easily identified at any time. .

  Further, when the map display scale is changed, the next station is displayed when the detailed map is displayed, and the station name of a large station set in advance in the table is displayed when the wide area map is displayed.

  Moreover, the size of the character which displays the station name of the next station and the station which passed is changed and displayed. In this case, the next station is displayed with normal characters or large characters, but by displaying the elapsed station name with small characters, the direction of travel can be clearly understood and the amount of information on the screen can be reduced. The effect is reduced and it is easy to see clearly.

  Similarly, when it is possible to determine that you are on the train, the station name display is displayed in a larger size or displayed as usual, but it is determined that you are moving by a method other than a train such as a car or foot. When it is possible, the character is displayed small or not.

  Also, by comparing with the information in the timetable, the type of train currently on board (normal, rapid, etc.) is discriminated, and the station that stops next is displayed without displaying the name of the passing station. At this time, if other lines that are not on the board are displayed on the same map, the station name information is displayed in a small size, so that the display can be clearly displayed with a clear appearance.

  In addition, when the station name is displayed, if there is a transfer to another line, the line name that can be transferred is also displayed. For example, if you are on the Yamatoji line, if the next station is Yamatokoriyama, you will see only “To Yamatokoriyama”, but if you are Nara, you will see “Nara Line, Kyoto” next to “To Nara”. “Line transfer” is displayed.

  With the above-described configuration, the user who has the navigation device 1 can always know the station where he / she stops next when moving by using a train, and worry about getting on and off smoothly. Can be reduced. Also, when traveling, you can immediately know how many stations are next and you can boost your mood. In addition, when moving by car, it is possible to immediately determine the nearest station, and the station name that would have been known until the nearest station search would be known immediately.

  As described above, in the navigation device 1 of the present embodiment, the latitude / longitude determination unit 22 that acquires position information including information on the current latitude and longitude, and the map display determination unit that displays a map image corresponding to the position information. 24, a track DB 44 and a station name DB 56 for storing track information indicating the position of the track and the station by latitude and longitude, and a plurality of the position information acquired by the latitude / longitude determination unit 22; When the information indicating the position of the track of the track information stored in the track DB 44 and the station name DB 56 matches, the boarding determination unit 12 that determines that the own device is moving with the train, and the track information, When the destination determination unit 20 that acquires connection destination information indicating the connection destination of the track and the boarding determination unit 12 determines that the own device is moving with the train, the destination Among the information acquired by the disconnection unit 20, the display place name determination unit that displays the connection destination information that is not displayed in the map image displayed by the map display determination unit 24 in correspondence with the end of the track in the map image. 28 is provided.

  In addition, the information presentation method of the embodiment includes a latitude / longitude determination unit 22 that acquires position information including current latitude and longitude information, and a map display determination unit 24 that displays a map image corresponding to the position information. The navigation device 1 further includes a track DB 44 and a station name DB 56 for storing track information indicating the position of the track and the station by latitude and longitude, and the latitude / longitude determination unit 22 acquires the information. A boarding determination step of determining that the own apparatus is moving together with the train when the plurality of position information matches the information indicating the position of the track in the track information stored in the track DB 44 and the station name DB 56 (S108). To S109) and a connection destination information acquisition step of acquiring connection destination information indicating a connection destination of the line based on the line information. S115-S117, S119) and the map image displayed by the map display determination unit 24 among the information acquired in the connection destination information acquisition step when it is determined in the boarding determination step that the own apparatus is moving with the train. A connection destination information display step (S118, S120) for displaying the connection destination information not displayed on the map in correspondence with the end of the track in the map image.

  According to said structure, in the information presentation apparatus which displays the map image corresponding to the acquired positional information, the position of the track and station shown by the latitude and longitude is memorize | stored, and based on the change of present positional information, and track information Is displayed in the map image when it is determined that the information presentation device is moving together with the train, the connection destination information indicating the connection destination of the track is acquired, and the information providing device is determined to be moving together with the train. Connection destination information that is not displayed is displayed in correspondence with the end of the track in the map image.

  Thereby, the navigation apparatus 1 displays the connection destination information that is not displayed in the map image in association with the end of the map image. Therefore, it is possible to display connection destination information that has been associated with a user-friendly relationship. Thereby, the user can grasp at a glance the destination of the train on which the user is on.

  In the navigation device 1 described above, the display place name determination unit 28 changes the content displayed as the connection destination information according to the display scale of the map image.

  According to said structure, the display place name judgment part 28 changes the content displayed as connection destination information according to the change of a display scale. For example, when the scale is small, the next station is displayed as the connection destination, and when the scale is large, a large station such as a terminal station where the express train stops is displayed as the connection destination. Thereby, the navigation apparatus 1 can show information of adjacent stations in association with the scale and present it to the user.

  Therefore, since the station information that the user wants to refer to is presented, the convenience for the user is improved.

  In the navigation device 1 described above, when the boarding determination unit 12 determines that the own device is moving together with the train, the boarding determination unit 12 determines the traveling direction of the train from the change in the position information acquired by the latitude / longitude determination unit 22, and the display place name The determination unit 28 displays the connection destination information displayed in the traveling direction of the train in a large size, displays the connection information displayed in the direction opposite to the traveling direction of the train, and displays the information in the direction opposite to the traveling direction of the train. The connection destination information is displayed in a small size.

  According to said structure, when the boarding judgment part 12 judges that the navigation apparatus 1 is moving with the train, the change of the positional information which the latitude longitude determination part 22 acquired, if a specific example is given, the present position The user who owns the navigation device 1 gets on by comparing the information and the change in the position information one minute ago, obtaining the moving direction and moving distance as changes in the position information, and referring to the traveling direction of the track and the connection destination. The direction of travel of the train being operated is determined, and the display place name determination unit 28 displays the connection destination information in the traveling direction larger and the connection destination information in the opposite direction smaller according to the traveling direction.

  As a result, the navigation device 1 displays a large amount of information that is highly likely to be referenced among connection destination information that the user refers to as a destination, and displays information that is considered to be less important. Therefore, the user can preferentially refer to necessary connection destination information in an easy-to-understand manner.
