ANALYZING A MOBILE DEVICE'S MOVEMENT PATTERN DURING A PRESSURE CHANGE TO DETECT THAT A STATE OF AN AIR CONDITIONING SYSTEM HAS CHANGED

摘要

Disclosed is an approach for detecting that a state of an air-conditioning system in a building has changed and ultimately determining the air-conditioning system's operating pattern, which could help improve collection and/or use of crowdsourced data for an indoor positioning solution and thus lead to more accurate position estimates. According to the disclosed approach, processor(s) may receive pressure and movement data from a mobile device. The pressure data may indicate a pressure change, and the movement data may indicate a movement pattern of the mobile device that occurred substantially during the pressure change. Given this, processor(s) could make a determination that the movement pattern lacks a substantial change in altitude of the mobile device during the pressure change and could use this determination as basis to detect that the state of the air-conditioning system has changed.
