Video System Can Measure Heartbeats Through Head Movement [Video]
Researchers at MIT have developed a new way to track the human heart rate.
A team of researchers from the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology has developed an algorithm that can measure one's heart rate through videos by analyzing the small and imperceptible movements of the head.
These head movements, which are caused by blood flow occurring during heart contractions, are difficult to see with the naked eye but can be detected using video amplification.
Tests using the system showed that the algorithm yielded pulse measurements that were nearly as exact as that of measurements produced by standard electrocardiograms or EKGs.
