  The operation unit 13 includes a plurality of mechanical switches provided in the vehicle navigation device 1 and an input device such as a touch panel provided on the display surface of the image display device 12. The user presses the mechanical switch and touches the touch panel. Is output to the control circuit 17.

  The map data acquisition unit 16 includes a nonvolatile storage medium such as an HDD (magnetic storage medium) and a device that reads and writes data from and to the storage medium. The storage medium stores a program executed by the control circuit 17, map data for route guidance, music data, and the like.

  The map data has road data and facility data. The road data includes link position information, type information, node position information, type information, information on connection relations between nodes and links, and the like. The facility data has a plurality of records for each facility, and each record has data indicating name information, location information, land lot number information, genre (facility type) information, etc. of the target facility. .

  The music group data consists of a plurality of music groups, and each music group includes a plurality of music data. Each music group corresponds to, for example, one CD album. In this case, the music data included in the music group is music data of music recorded in the CD album.

  A control circuit (corresponding to a computer) 17 is a microcomputer having a CPU, RAM, ROM, I / O and the like. The CPU executes a program for the operation of the vehicle navigation device 1 read from the ROM or the map data acquisition unit 16, reads information from the RAM, the ROM, and the map data acquisition unit 16 when executing the program. Information is written to the storage medium of the map data acquisition unit 16 (if possible), and signals are exchanged with the position detector 11, the image display device 12, the operation unit 13, and the speaker 14.

  Specific processing performed by the control circuit 17 executing the program includes music reproduction processing, current position specifying processing, map display processing, guidance route calculation processing, route guidance processing, and the like.

  The current position specifying process is a process for specifying the current position and direction of the vehicle based on a signal from the position detector 11 using a known technique such as map matching.

  The music reproduction process is a process of accepting an operation of music designation by the user from the operation unit 13, reading out music data corresponding to the designated music from the music group data and playing it, and outputting the sound of the music to the speaker 14. .

  The map display process is a process for causing the image display device 12 to display a map of a specific area such as the vicinity of the current position of the vehicle. At this time, information used for map display is acquired from the map data.

  The guidance route calculation process is a process of accepting a destination designation operation by the user from the operation unit 13 and calculating an optimum guidance route from the current position to the destination.

  The route guidance process is a process that guides the travel along the calculated guidance route, sequentially monitoring the positional relationship between the guidance route and the vehicle position, and before a guidance point such as a right-left turn intersection on the guidance route. When the host vehicle arrives, a guidance voice instructing a right turn, a left turn, etc. is output to the speaker 14, and an enlarged view of the guidance point is displayed on the image display device 12, thereby driving the vehicle along the guidance route. It is a process to guide.

  In the above process, the control circuit 17 may perform a list display control process for displaying a list of items on the image display device 12 in order to allow the user to select one of a plurality of items. For example, in order to accept a music designation operation by the user in the music reproduction process, display control of the music group list and the music list is performed.

  Specifically, first, a music group list is displayed on the image display device 12 in order to accept a music group designation operation by the user. All items included in the music group list correspond one-to-one with all music groups recorded in the music group data.

  When the user designates one music group using the operation unit 13, the music display list included in the music group is displayed on the image display device 12 in order to accept the user's operation for designating the music in the music group. . All items included in the music list of a certain music group have a one-to-one correspondence with all music data in the music group. When the user uses the operation unit 13 to select one from the music list, the music specification is completed.

  In the case of performing the list display control process, for example, the display control of the genre list and the facility list is performed in order to accept a destination designation operation in the guidance route calculation process.

  Specifically, first, a genre list is displayed on the image display device 12 in order to receive a music group designation operation by the user. All items included in the genre list correspond to one genre in all genres set in advance in the map data. The genre is the type of destination (amusement park, restaurant, shrine and temple, etc.).

  Then, when the user designates one genre using the operation unit 13, the facility display of the genre is displayed on the image display device 12 in order to accept an operation of designating the facility within the genre by the user. All items included in the facility list of a certain genre have a one-to-one correspondence with all the facilities belonging to the genre in the map data. When the user selects one from the facility list using the operation unit 13, the designation of the facility as the destination is completed.

  In such list display control processing, the total number of items included in the list to be displayed may be different for each list. Even in the same list, the total number of items in the list may change due to additional registration and deletion of new items by the user.

  FIG. 2 shows a flowchart of the list display control process. The control circuit 17 reads the program from the ROM or the HDD of the map data acquisition unit 16 and executes it, thereby realizing the operation of the list display control process.

  First, in step 110, a list to be displayed on the image display device 12 (hereinafter referred to as a target list) is read. When reading the music group list or the music list, the music group data is read from the music group data. When reading the genre list or the facility list, the data is read from the map data (more specifically, the facility data).

  In step 120, the total number of items included in the target list is specified. This total number is the total number of music groups included in the music group data in the case of a music group list, the total number of music data included in the music group in the case of a music list of a certain music group, The total number of genres included in the map data. In the case of a facility list of a certain genre, the total number of facilities in the map data belonging to the genre.

  Subsequently, in step 130, it is determined whether or not the total number of identified items is equal to or less than the threshold value n. If the threshold value is equal to or less than the threshold value n, the process proceeds to step 135. The value of the threshold value n is a threshold value for determining whether or not all items of the target list can be displayed simultaneously on one display screen of the image display device 12. The threshold value n varies depending on the size of the display screen of the image display device 12 or the like, but may be about 15, for example.

  In step 135 executed when it is determined that display is possible within one display screen, the display size (vertical width, horizontal width) of each item to be displayed within the display screen of the image display device 12 is determined. This size decreases as the total number of items specified in step 120 increases. In this way, when the number of items included in the target list is very small compared to the threshold value n (for example, when the total number of items is 4 with respect to the threshold value n = 15), each item is displayed in a large size. Therefore, the visibility of the user is improved. The item size is the same between items.

  Subsequently, in step 140, as shown in FIG. 3, all items 21 to 30 included in the target list are simultaneously displayed on the display screen 20 of the image display device 12 with the display sizes determined in step 130, respectively. And the arrangement | sequence of the items 21-32 is ring shape. More specifically, in each of the horizontally long items 21 to 32, a ring shape is obtained by connecting the center positions of the items 21 to 32 in the left-right direction.

  Furthermore, in such a ring-shaped arrangement, some of the items 28 to 32 located on one side of the ring in the left-right direction (specifically, the right side) are partially on the other side in the left-right direction (specifically, the left side). It is in a state hidden behind the positioned items 22 to 26 (the back side of the screen). As a result, the items 21 to 32 appear to be arranged in a three-dimensional ring shape inclined in the depth direction of the display screen 20. By arranging the items 21 to 32 three-dimensionally in this way, the appearance of the list is improved.

  Each item 21 to 32 has a name of the item (a song group name in the case of a song group list, a song name in the case of a song list, a genre name in the case of a genre list, and a facility in the case of a facility list). Character string) is displayed. At this time, in the items 28 to 32 that are partially hidden behind the other items, a part of the name character string is not visible. By moving to a position that is not hidden behind the item, the entire name string can be seen.

  If it is determined that it cannot be displayed on one display screen, some of the items 41 to 54 out of all items included in the target list are transferred to one of the image display devices 12 as shown in FIG. Display simultaneously on the display screen. And the arrangement | sequence of the items 21-32 is arched. More specifically, when the horizontal positions of the items 41 to 54 of the horizontally long items 41 to 54 are connected to each other, an arch shape (more specifically, an arc shape) is obtained.

  Therefore, since the shape of the array of the items 41 to 54 is a curved shape with a part of the ring missing, the user intuitively receives the impression that there are items that are not displayed (the missing items).

  Also in this case, a name character string is displayed in each item. In FIG. 4, the items 50 to 54 that are partially hidden behind the other items 41 to 45 are also moved to positions that are not hidden behind the other items by being moved by a feeding operation as described later. As a result, the entire name string can be seen.

  To do so, the control circuit 17 first determines the shape of the arch which is the arrangement of the items 41 to 54 in step 145. Specifically, the larger the total number of items specified in step 120, the smaller the arc-shaped curvature (that is, the larger the radius of curvature). For example, when the total number of items is larger than that in FIG. 4, the curvature of the arc shape is reduced as shown in FIG.

  Note that the number of items displayed in one display screen 20 varies depending on the curvature of the arc shape. If the total number of items is small and the curvature of the arc is large as in the case of FIG. 4, there are items 50 to 54 that are partially hidden behind the other items 41 to 45. This is because if the total number of items is large and the curvature of the arc is small as in the case of FIG. 5, there is no item that is partially hidden behind other items.

  Subsequently, in step 150, the arch having the shape determined in step 145 is displayed on the display screen 20. Of all the items in the target list, the display number M to be displayed on the display screen 20 at the same time is set so as to decrease as the total number of items increases for the reasons described above. The M items to be displayed among all items may be M at the top of the list or M selected by other methods.

  After steps 140 and 150, the list display control process ends, but thereafter, the control circuit 17 continues to display the items of the target list in the display screen 20.

  Thus, the control circuit 17 specifies the number of items included in the target list (step 120), determines whether the total number of the specified items is equal to or less than the threshold value n (step 130), and the total number is equal to or less than the threshold value n. In some cases, all items included in the target list are arranged and displayed in a ring shape on one display screen 20 of the image display device 12 (135, 140). If the total number exceeds the threshold value n, the list includes. Some of the items are arranged and displayed in an arch shape on one display screen 20 of the image display device 12 (145, 150).

  In this way, if all the items in the list are displayed, the items are displayed in a ring array, and if there are items that are not displayed in the list, they are part of the ring. Items are displayed in an array of curved shapes lacking. Therefore, the user can grasp whether there are items that are not displayed in the list or whether all the items in the list are displayed based only on the shape of the array of items. In addition, the curved shape lacking a part of the ring is a shape that intuitively gives the user the impression that there is an item that is not displayed, so it is intuitively easy to understand. Yes.

  In the case of displaying in an arch shape, the curvature of the arch shape is reduced as the total number of items increases. Conventionally, when there are a large number of items in the list, it is impossible to grasp from the display of the items how much of all the items are currently displayed on the screen. There is a case where it is not easy to know how long the target item can be found by performing a scroll operation, a page feed operation, etc.

  Then, by doing as mentioned above, the user can grasp | ascertain the ratio of the number of display items with respect to the total number of items according to the curvature of the curve shape of an item arrangement | sequence. Further, when the curvature of the curved shape is larger, an impression that the current display part is a part of a larger ring is received, so that the display is easy to understand intuitively.

  The control circuit 17 adds a mark as shown in FIG. 6 by executing a predetermined program after performing the ring-like display and the arch-like display exemplified in FIGS. 3 to 5 by the list display control process. Processing is to be executed.

  In the mark addition process, first, in step 230, the process waits until the user performs a predetermined mark addition operation for one of the items displayed on the display screen 20. When the user performs a mark addition operation on one item using the operation unit 13, the process proceeds to step 240, and as shown in FIG. A rectangular mark image 60 smaller than 21 is added. If it does in this way, since it will seem that the tag was stuck on the said item 21, the said item 21 will be conspicuous rather than another item. After step 240, the process returns to step 230 and waits until there is a mark addition operation for another item.

  In addition, the control circuit 17 performs ring-like display and arch-like display as exemplified in FIGS. 3 to 5 by the list display control process, and then executes a predetermined program to perform a feed process as shown in FIG. It is supposed to run. This feeding process is executed in parallel with the mark addition process of FIG.

  In this feed process, the control circuit 17 first waits until the user performs a feed operation on the operation unit 13 in step 210. The feed operation refers to a process of moving items within the display screen 20 along the array (ring-shaped array or arch-shaped array). In the feed operation, the feed direction (forward direction, reverse direction) and movement amount can be specified.

  When the user performs a feed operation, in step 220, the displayed items are moved along the arrangement in the feed direction according to the feed operation by the amount of movement according to the feed operation.

  By such processing, if items are displayed in a ring-shaped arrangement, the items move forward or backward along the ring shape, and the entire list appears to rotate.

  In addition, when an item is displayed in an arch shape arrangement, the item moves forward or backward along the arch shape. At this time, items that move out of the display screen 20 due to movement are excluded from the display target, and other items in the same number as the items excluded from the display target are extracted from the target list. Display in an empty space by moving the item. By doing so, the items appear to be scrolled along the arch shape by the feeding operation.

  In this step 220, if the mark image 60 is added to the item to be moved, the mark image 60 is also moved together with the item while maintaining the relative positional relationship with the item.

  As described above, the control circuit 17 moves with the item that is the target of the mark addition operation based on the user performing the mark addition operation for one of the items displayed on the display screen 20. 60 is additionally displayed on the image display device 12.

  With this configuration, the position of an item that has been selected can be easily grasped by a mark even when a feeding operation is performed. In addition, the amount of feed of the item can be grasped from the amount of movement of the mark.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. This embodiment is different from the first embodiment only in the shape of items displayed on the display screen 20 by the list display control process.

  FIG. 9 shows an example of the item 70 that the control circuit 17 displays on the display screen 20 in the list display control process of the present embodiment.

  As shown in this figure, the control circuit 17 looks like a solid (specifically a rectangular parallelepiped) surrounded by a plurality of surfaces, with each shape of a plurality of items arranged in a ring shape or an arch shape on the display screen 20. It has a shape like this.

  Furthermore, the name of the item (more specifically, the name of the facility) is displayed on the front surface of the solid, and the upper surface of the solid has a type other than the name of the item. Display text information on the item (specifically, the contact phone number of the facility). In this way, the display contents of one item are displayed separately for each type, so that the user can easily read the display information.

(Third embodiment)
Next, a third embodiment of the present invention will be described. The present embodiment is different from the first and second embodiments in that the control circuit 17 changes the items 21 to 32 included in the target list in the display screen 20 in the list display control process as shown in FIG. In the same display screen 20, the items included in the lists 81 and 82 other than the target list are also displayed in the ring shape or the arch shape. It is to be displayed with.

  For example, in the list display control process, when the items 21 to 32 included in the song list of the first song group are displayed in step 140 or 150, the second song is displayed at the upper left of the items 21 to 32. All items included in the music list 81 of the group are arranged in a ring-shaped arrangement, and all items included in the music list 82 of the third music group are arranged in a ring-shaped arrangement at the upper right of the items 21 to 32. It may be like this.

  In this case, display of character strings is omitted for all items included in the music lists 81 and 82. In this way, the size of the item can be made very small. As a result, even if the total number of items included in the music list 81, 82 is very large (for example, the total number exceeds 30). All items can be displayed in the display screen 20.

  In this way, in the screen that displays the items included in the target list, all the items included in the other list are displayed in a ring shape for a list different from the list including the item. As a result, the number of lists other than the target list can be grasped.

  In each of the above embodiments, the control circuit 17 functions as an example of the total number specifying unit by executing Step 120, functions as an example of the determining unit by executing Step 130, and executes Steps 135 and 140. By doing so, it functions as an example of a ring-shaped display unit, and by executing steps 145 and 150, it functions as an example of a partial display unit.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, although the arch shape in the above embodiment is an arc shape, it may be a curved shape with a part of the ring missing regardless of the arc shape.

  In the above embodiment, each function realized by the control circuit 17 executing the program is realized by using hardware having those functions (for example, an FPGA capable of programming the circuit configuration). You may come to do.

  In addition, the music group data is not limited to the storage medium of the map data acquisition unit 16, and other storage mediums that can keep the data even when the main power supply of the vehicle navigation device 1 is stopped. (For example, flash memory, EEPROM, backup RAM, HDD) may be stored. In that case, the storage medium of the map data acquisition unit 16 does not have to be a writable storage medium such as an HDD, and may be a non-writable storage medium such as a DVD or a CD-ROM.

  Further, the navigation device of the present invention does not necessarily have to be mounted on a vehicle. For example, the navigation device may be of a type carried by the user, or of a type mounted on a moving body other than a vehicle (for example, a ship, an aircraft, etc.).
