1. A method of utilizing a personal navigation system comprising:
- providing navigation to a user, the navigation specifying directions from a first location to a second location;
automatically determining a mode of travel of the user, the automatically determined mode of travel selected from among;
a muscle-powered vehicle, and ambulatory motion; and
calculating the directions based on the mode of travel, the mode of travel defining a set of constraints for the navigation, such that a route selection is altered based on the mode of travel, wherein the set of constraints includes one or more of traffic level, one way streets, walking paths, trails, presence of sidewalks, presence of bicycle paths, and change in elevation.

Abstract
A method or apparatus to provide a global positioning system receiver is described. The Personal navigation system includes at least one motion sensor, the motion sensor capable of identifying a user activity, and distinguishing between walking and driving, or other manual v. mechanical locomotion. The system automatically switches modes to the appropriate format.

13. A method of utilizing a personal navigation system comprising:
-
receiving a target destination; receiving an intermediate destination to be reached by the user using a first mode of travel; calculating directions based on the first mode of travel, the mode of travel defining a set of constraints for the navigation, such that a route selection is altered based on the mode of travel, wherein the set of constraints includes one or more of traffic level, one way streets, walking paths, presence of sidewalks, presence of bicycle paths, and change in elevation; and providing navigation to a user, the navigation specifying the directions from a first location to the intermediate location; upon reaching the intermediate destination, automatically determining whether the mode of travel of the user has changed, the automatically determined modes of travel selected from among;
ambulatory motion and a motorized vehicle; andcalculating the directions to the target destination using a new mode of travel when the mode of travel has changed. - View Dependent Claims (14, 15, 16, 17, 18)
