METHOD AND APPARATUS FOR DISPLAYING THREE-DIMENSIONAL ROUTE GUIDANCE
First Claim
1. A navigation system comprises:
- a user interface including a three-dimensional scene generating unit adapted to generate the three-dimensional scene from two-dimensional scene information;
an information receiver adapted to receive information about current location of a user;
at least one database to store and provide maps, road networks, geographical features, and point-of-interest (POI) information;
a route generating unit to retrieve the map and road network data from the database and generate a calculated route; and
a map adjusting unit,wherein the map adjusting unit is communicatively coupled with the database and the route generating unit to change curvature of a visual ground in the map to provide route guidance in a three-dimensional format to the user.

Abstract
This invention relates to a route displaying method and apparatus in a navigation system. More specifically, this invention relates to a navigation-based apparatus and method to display a complete route presented in three-dimension. The navigation system may include a map adjusting unit to adjust visual ground of the map for the user. In one embodiment, the map adjusting unit can adjust the visual ground area convexly, so that the user can view the full route including the destination. In another embodiment, the map adjusting unit may adjust the visual ground area concavely to present more surrounding details of the vehicle to the user. The navigation system may also include a wireless communication device to retrieve the most current map and traffic information from a remote server, and communicatively couple with the map adjusting unit and a route generating unit to provide the most updated information with full route view to the user. The navigation system may also be integrated into a portable device such as a smartphone.
