Power efficient activation of a device movement sensor module

摘要

The functionality described herein allows a user device to determine an appropriate juncture at which to initiate processing within a global navigation satellite system (GNSS) dead zone in an energy-efficient manner. In one implementation, the functionality employs a sensor management module for determining when to activate a device movement sensor module provided by a user device. When activated, the user device uses the device movement sensor module to perform any environment-specific processing, such as a dead-reckoning process for determining incremental positions within the venue. Further, in a crowd-sourcing application, the user device may report the incremental positions together with beacon information to remote processing functionality.

1. A method implemented by one or more processing devices, the method comprising:
identifying a first identified region based on a first distance of a current position of a user device from a venue, the first identified region being one of a plurality of regions with respective distances from the venue; selecting a first probing technique associated with the first identified region, the selecting based in part on the first distance of the user device from the venue, wherein the first probing technique is not associated with a second identified region associated with the venue; and performing the first probing technique while the user device is in the first identified region to determine a new current position of the user device.
