Mirror, Mirror on the Wall, What’s my Heart Rate After All?

 

An MIT graduate student has developed a way of monitoring a person’s vital signs by just putting then in front of an ordinary webcam.

 

Ming-Zher Poh has demonstrated that the system can indeed extract accurate pulse measurements from ordinary low-resolution webcam imagery. Now he’s working on extending the capabilities so it can measure respiration and blood-oxygen levels. He hopes eventually to be able to monitor blood pressure as well. Initial results of his work, carried out with the help of Media Lab student Daniel McDuff and Professor of Media Arts and Sciences Rosalind Picard, were published earlier this year in the journal Optics Express.
