Abstract

A navigation device 100 having a function to modify a route comprises an operational object detecting part 11 configured to detect a point or a section on the route as an operational object, a fixed point setting part 12 configured to set as fixed points two points on the route sandwiching the operational object therebetween, an operational object displacement detecting part 13 configured to detect a displacement of the operational object, a path changing part 14 configured to change a path of the route depending on the displacement of the operational object while elongating or contracting a line connecting the operational object and the fixed point, and a route re-searching part 15 configured to re-search and display an alternate route continuously depending on the changing path.

Claims

1. A navigation device having a function to modify a route comprising:

an operational object detecting part configured to detect a point or a section on the route as an operational object;

an operational object displacement detecting part configured to detect a displacement of the operational object;

a path changing part configured to change a path of the route depending on the displacement of the operational object in real time; and

a route re-searching part configured to re-search an alternate route based on the changed path.

2. A navigation device according to claim 1, further comprising:

a fixed point setting part configured to set as fixed points two points on the route sandwiching the operational object therebetween,

wherein the path changing part elongates or contracts a line connecting the operational object and the fixed point in conjunction with the displacement of the operational object.

3. A navigation device according to claim 2, wherein the fixed point includes a departure point, a destination point, an edge point of the route displayed on a screen, or a turning point on the route.

4. A navigation device according to claim 1, wherein the operational object is designated by one or more points on the route.

5. A navigation device according to claim 1, wherein the operational object displacement detecting part detects the displacement of the operational object based on a drag operation of the operational object.

6. A navigation device according to claim 1, comprising at least one of a touch panel, a touch pad, a mouse, a track ball, a joystick, or a remote control with an arrow key.

7. A navigation device according to claim 1, wherein the path changing part changes and displays a path of the route in real time depending on the displacements of the operational objects, continuously.

8. A navigation device having a function to modify a route comprising:

an operational object detecting part configured to detect a point or a section outside the route as an operational object;

a fixed point setting part configured to set as fixed points two points on the route sandwiching the operational objects detected by the operational object detecting part therebetween;

a path changing part configured to change a path of the route to a changed path including the operational objects and the two fixed points and display the changed path; and

a route re-searching part configured to re-search and display an alternate route based on the changed path.
