Systems and methods for tracking a user's location

摘要

Techniques for tracking a current location of a user are described. According to various embodiments, an ambient noise signal proximate to a user device is detected using a microphone. Audio sample information may be accessed, where the audio sample information identifies various audio samples and, for each of the audio samples, a source of the corresponding audio sample. Thereafter, a specific audio sample corresponding to the ambient noise signal may be identified. Moreover, a current location of the user device may be determined, based on the source of the specific audio sample.

主权项

1. A method comprising:
detecting, using a microphone of a user device, an ambient noise signal proximate to the user device; accessing audio sample information identifying a plurality of audio samples and, for each of the audio samples, a source of the corresponding audio sample; identifying, from the audio sample information, a specific one of the audio samples that corresponds to the ambient noise signal; determining, using one or more hardware processors, a current location of the user device, based on the source of the specific audio sample; detecting, using a temperature sensor of the user device, an ambient temperature proximate to the user device; estimating, based at least in part on global positioning system information, a position of the user device; accessing weather information indicating a current outdoor temperature for the estimated position of the user device; comparing the detected ambient temperature to the current outdoor temperature; and determining that the user device is currently located indoors or outdoors, based on the comparison.
