Abstract
A method and system for tracking an activity is described. A location tracking engine tracks a user's location, determines a direction by identifying a plurality of angles ahead of the current location on the path, and conveys navigation information to the user. A filter module receives a location update from a location tracking engine. The filter module performs at least one test on the location update. The filter module adds the location update to a queue of recently received location updates in response to passing the test. The stop detector module determines that the user is stopped and sets the current status to stopped and sets a time of a stop detection change to the later of the last time that of the stop detection change and a timestamp of the oldest location update in the queue if a previous status is moving.
