Abstract
A method and 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.
Claims24
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 motorized vehicle, 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, presence of sidewalks, presence of bicycle paths, and change in elevation.

A personal navigation system including modes, comprising:
- a mode selector to automatically determine a mode of travel of the user, the mode of travel selected from among:
- a motorized vehicle, a muscle-powered vehicle, and ambulatory motion;
- and
- a direction calculator to provide navigation based on the mode of travel, the direction calculator receiving input from a mode logic, to route based on constraints associated with the determined mode of travel of the user, 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.
1 more element
A personal navigation system comprising:
- a mode selector to utilize sensor data to automatically determine a mode of travel of a user, the mode selected from among motorized vehicle, muscle-powered vehicle, and ambulatory motion;
- a navigation module to calculate a navigational path for a user based on the mode of movement, the path meeting a plurality of constraints associated with the mode of movement, the constraints including one or more of:
- road data and traffic data.
A personal navigation system comprising:
- user context logic to determine a user's current context in using the personal navigation system, the context logic to identify a switch in context when detecting the user exiting a vehicle;
- and
- navigation module to provide navigation based on the user's current context and location information, a route selected based on constraints associated with the user's current context, such constraints including one or more of:
- speed limits, directionality, traffic levels, bike lane availability, walking paths, vertical change, and public transportation options.
