Abstract
A navigation system includes a display which provides a 3-D perspective view. The angle of viewing in the perspective view is increased based upon the complexity of the intersection being displayed. Intersections of increased complexity are displayed at an increased viewing angle to facilitate understanding. A sky above a horizon on the display changes color based upon the time of day.
Claims20
A vehicle navigation system comprising:
- a database of roads to be traveled by a vehicle;
- a processor determining a viewing angle based upon a complexity of an intersection in said database;
- a display displaying said intersection at a perspective view calculated at the viewing angle.
A method for navigating a vehicle including the steps of:
- a) determining a route from a database of roads to a desired destination, said route including an intersection;
- b) determining a complexity of said intersection;
- c) determining a viewing angle based upon said complexity of said intersection;
- and
- d) displaying said intersection as a perspective view at said viewing angle.
