Key result
RespTracker, a continuous multi-person respiration tracking system using acoustic COTS devices, distinguished the respiration of at least four subjects over a distance of three meters.
Why the study?
Continuous domestic respiration monitoring provides vital information for diagnosing assorted diseases, but continuous multi-person tracking systems using acoustic COTS devices are lacking.
RespTracker demonstrates the feasibility of using acoustic-based COTS devices for continuous, multi-person respiration tracking in domestic settings.
Answers are grounded in this paper and cite their sources.
RespTracker enables initial multi-person home respiration tracking; leaves open clinical validation before diagnostic use in cardiovascular care.
Continuous domestic respiration monitoring provides vital information for diagnosing assorted diseases. In this article, we introduce RespTracker , the first continuous, multiple-person respiration tracking system in domestic settings using acoustic-based COTS devices. RespTracker uses a multi-stage algorithm to separate and recombine respiration signals from multiple paths so that it can track the respiration rate of multiple moving subjects. And it leverages features from multiple dimensions to separate different users in the same area. Our experimental results show that our two-stage algorithm can distinguish the respiration of at least four subjects and cover a distance of three meters.
