Patent Images
1. A method of operating a navigation system comprising:
- receiving a request for a pedestrian route between a first location inside a building and a second location inside the building;
accessing a geographic database stored on a computer readable medium associated with the navigation system to obtain data representing a plurality of pedestrian paths located inside the building, wherein at least one of the pedestrian paths is identified from a floor plan of the building;
determining a route comprising a series of connected pedestrian paths between the first location and the second location;
accessing the geographic database to obtain data representing a feature visible from at least one of the pedestrian paths of the route; and
providing a guidance message for following the route, wherein the guidance message identifies the feature.

Abstract
A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request for the pedestrian route between a first location inside a building and a second location inside the building is obtained. A geographic database associated with the navigation system is accessed for data representing a plurality of pedestrian paths. A solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths between the first location and the second location is determined. A guidance message that identifies a feature visible from at least one of the pedestrian paths is provided.

10. A navigation system comprising:
-
a processor, a geographic database stored on a computer readable medium associated with the processor, a route calculation program executed on the processor, wherein the route calculation program receives a request for a route between a first location in a building and a second location inside the building, and determines a solution route comprising a series of connected pedestrian paths between the first location and the second location, and a route guidance program executed on the processor, wherein the route guidance program provides at least one guidance message for following the solution route, wherein the guidance message references a feature visible from at least one of the pedestrian paths of the solution route. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
