USER LOCATION TRACKING

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving information from a remote system comprising one or more time periods during which a location of the client device can be tracked and monitoring the location of the client device during each of the time periods by obtaining a plurality of location coordinates from the client device during the time period and persistently storing the location coordinates on the client device.

主权项

1. A computer-implemented method comprising:
obtaining by a client device a plurality of locations of the client device at different times, each location being associated with a respective bearing and speed of the client device; for each of the locations, if the associated speed is in a first speed range that is greater than zero miles per hour:
calculating a change in bearing from a previously obtained bearing and the bearing associated with the location;if the change in bearing exceeds a bearing threshold saving the location and the associated bearing and speed; and sending the saved locations and associated bearings and speeds to a remote system.
