Abstract
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.
