Natural navigational guidance
First Claim
1. A method of providing visual natural navigational guidance output from a wireless navigation device, comprising:
- determining a geographic location of said wireless navigation device based on location data provided by a navigation application program;
measuring a current location and direction of travel of a wireless navigation device with respect to an upcoming maneuver point based on map data characterizing a geographic area;
determining a natural guidance point selection area relating to said upcoming maneuver point based on said map data;
determining available geographic features from a plurality of geographic features within said natural guidance point selection area based on said map data, wherein each geographic feature includes a plurality of visual characteristics identified in said map data;
comparing each geographic feature against each other geographic feature based on said respective plurality of visual characteristics to determine at least one locally unique geographic feature from said available geographic features;
selecting a highest priority locally unique geographic feature of said at least one locally unique geographic features within said determined natural guidance point selection area based on a proximity of said highest priority locally unique geographic feature to said upcoming maneuver point; and
displaying visual navigation guidance on said wireless navigation device, said visual navigation guidance relating an upcoming maneuver to be navigated at said upcoming maneuver point to said highest priority locally unique geographic feature.

Abstract
Natural navigational guidance provides enhanced guidance instructions that take advantage of unique geographic features along a navigated route to specify maneuver points. Guidance points are clearly visible, unambiguous, and locally unique features in the geography of the maneuver area that can be used to aid the user in discovering the place where the maneuver point is. Within a guidance point selection area, a specific guidance point type has a more strict area within which it can be used. A natural guidance point selection area for an upcoming maneuver to be navigated is determined, and a unique geographic feature within the determined natural guidance point selection area is selected as a natural guidance point for navigation of the upcoming maneuver. A turn-type natural guidance point for an upcoming maneuver to be navigated is generated when the user device is within the natural guidance point selection area.
