[Display example]
The present invention displays the moving display according to the moving speed of the terminal device 1 when performing route guidance based on the guidance route obtained by the route search, so that the distance to the guidance point visually and intuitively. It is characterized in that it can be easily grasped.

(First display example)
One display example in the route guidance process is shown in FIG. In this display example, as shown in FIG. 2, a disk-shaped display body 11 as a moving display body is displayed on the display screen 10 of the display device 6. The disk-shaped display body 11 rotates in the direction of the arrow at a speed corresponding to the moving speed of the terminal device 1 that is a moving body.

  Further, a current position bar 12 is displayed on the display screen 10 as a current position display body indicating the current position of the terminal device 1. Since the current position bar 12 is displayed in a state of being fixed at a predetermined position in the display screen 10, the display position of the current position bar 12 does not change even if the terminal device 1 that is a moving body moves.

  Thus, the disk-shaped display body 11 rotates and moves relative to the current position bar 12 whose position is fixed. Further, the rotational speed of the disk-shaped display body 11 corresponds to the moving speed of the terminal device 1 which is a moving body. Therefore, visually, the rotation of the disk-shaped display body 11 indicates the movement of the terminal device 1 which is a moving body on the guide route. That is, if the terminal device 1 is moving at high speed, the disk-shaped display body 11 rotates at high speed, and if the terminal device 1 is moving at low speed, the disk-shaped display body 11 rotates at low speed.

  A plurality of equidistant marks 15 are provided at equal intervals on the side surface of the disk-shaped display body 11. Therefore, the interval between the equidistant marks 15 indicates a predetermined moving distance. When the terminal device 1 that is a moving body is moving at high speed, the disk-shaped display body 11 rotates at high speed, and a number of equidistant marks 15 pass through the current position bar 12 within a predetermined time. The user can intuitively and easily know the moving speed of the terminal device 1 from the moving speed of the equidistant mark 15.

  The equidistant mark 15 includes a normal equidistant mark 15a and an event mark 15b. The event mark 15b has a function as an equidistant mark, but in addition, it indicates that some event information is prepared at that position. For this reason, the event mark 15b is displayed in a different form from the normal equidistant mark 15a. In the example of FIG. 2, the event mark 15b is displayed as a shaded circular mark, and the normal equidistant mark 15a is displayed as a white circle mark. In addition, the distinction on display of normal equidistant mark and event mark is not limited to this method, and it is possible to distinguish on the display by changing the shape (circle, triangle, etc.), color, size, etc. of each mark. Can do.

  On the disk-shaped display body 11, a guide plate 13 is displayed as a guide information display body. The display position of the guide plate 13 on the disk-shaped display body 11 corresponds to the position of the guide point on the guide route. In the example of FIG. 2, the guide plate 13a shows a left turn, and the guide plate 13b shows a right turn. Therefore, in the route guidance example shown in the example of FIG. 2, at the timing when the guide plate 13a arrives at the position of the current position bar 12 by the rotational movement of the disk-shaped display body 11, turn left at the intersection where the terminal device 1 is at that time. The instructions to do are shown. After that, at the timing when the guide plate 13b arrives at the position of the current position bar 12, an instruction to turn right at the intersection where the terminal device 1 is present is shown. Guide plates 13c and 13d located on the back side of the disk-shaped display body 11 indicate future guidance information, and move to the front side of the disk-shaped display body 11 as the disk-shaped display body 11 rotates. Although the guide plates 13c and 13d are only partially visible on the back side, the user can know in advance that a guide point will arrive in the near future. In this example, the guide plate 13 shows an arrow indicating the direction of travel, but the direction of travel may be indicated by another design or the like. In addition to the arrows, intersection names and the like may be displayed.

  On the message board 14 above the current position bar 12, guidance information at the next guidance point on the guidance route is displayed in text. In the example of FIG. 2, guidance information for turning left in the direction of A (place name) is displayed at a guidance point corresponding to the next guidance plate 13a. When the event mark 15b has arrived at the current position bar 12, the corresponding event information can be displayed on the message board 14. For example, when information on nearby sightseeing spots is prepared as event information, the guidance information is displayed on the message board 14.

  As described above, in the first display example, the disk-shaped display body 11 rotates and moves at a speed corresponding to the moving speed of the terminal device 1 with respect to the current position bar 12 displayed at the fixed position. Since the equidistant mark 15 and the guide plate 13 are displayed on the body 11, the user can easily grasp the distance to the next guide point, the required time, etc. visually and sensibly.

(Second display example)
FIG. 3 shows a second display example. In the first display example shown in FIG. 2, the disc-like display body 11 is displayed as the moving display body, whereas in the second display example, the linear display body 21 is displayed as the moving display body as shown in FIG. Is done. Other than that, the configuration of the second display example is basically the same as that of the first display body.

  As shown in FIG. 3, an equidistant mark 25 is displayed on the linear display body 21. The equidistant mark 25 includes a normal equidistant mark 25a and an event mark 25b. The functions of the equidistant mark 25a and the event mark 25b are the same as in the first display example. Further, a guide plate 23 as a guide information display body is displayed on the linear display body 21 at a position corresponding to the guide point.

  A current position bar 22 as a current position display is displayed at the right end of the display screen in FIG. 3, and a message board 24 is displayed above it. The functions of the current position bar 22 and the message board 24 are the same as in the first display example.

  The example of FIG. 3 shows a state where the guide plate 23a has just arrived at the position of the current position bar 22. In the second display example, as indicated by a broken line arrow 29, the width of the linear display body 21 gradually increases in the vicinity of the current position bar 22, and the guide plate 23 is enlarged and displayed at the position of the current position bar 22. The

  Also in the second display example, the linear display body 21 as the moving display body moves so as to flow at a speed corresponding to the moving speed of the terminal device 1, and accordingly, the equidistant mark 25, the guide plate 23, and the like. Moves toward the current position bar 22. Therefore, the user can easily grasp the distance to the next guide point visually and sensuously.
