A machine learning system can help smart speakers locate signals from both regular and irregular heartbeats.
Using smart speakers and machine learning algorithms, researchers from University of Washington (UW) have developed a way to monitor both regular and irregular heartbeats without physical contact.
In a study published in Communications Biology, the team described how the system sends inaudible sounds from the speaker out into a room and, based on the way the sounds are reflected back to the speaker, it can identify and monitor individual heartbeats.
Because the heartbeat is such a small motion on the chest surface, the system uses machine learning to help the smart speaker locate both regular and irregular heartbeats.
Researchers noted that while most people...
