DETECTING GEO-FENCE EVENTS USING VARYING CONFIDENCE LEVELS

摘要

The location of a computing device is determined, and the location of an area of interest that is a geographic area referred to as a geo-fence is identified. The accuracy of the determined location of the computing device has an associated uncertainty, so the exact position of the computing device cannot typically be pinpointed. In light of this, the uncertainty associated with the determined location is evaluated relative to the size of the geo-fence in order to determine whether the computing device is inside the geo-fence or outside the geo-fence. Based on this determination, various actions can be taken if the user is entering the geo-fence, exiting the geo-fence, remaining in the geo-fence for at least a threshold amount of time, and so forth.

主权项

1. A method comprising:
identifying a size of a geo-fence; identifying a size of a position uncertainty area for a location determination module, the position uncertainty area being based on an estimated accuracy error of a location for a computing device provided by the location determination module; and determining occurrence of one or more geo-fence events for the geo-fence based on a confidence level that varies based at least in part on both the size of the geo-fence and the size of the position uncertainty area.
