Vitals Monitoring from 4’ away with a Smartphone
March 12, 2019 | Terry Sharrer
Engineers at Penn State and Johns Hopkins are collaborating in the development of a heart rate monitor that relies on a smartphone camera, and can take its readings from 4’ away, under different conditions. “Specifically, the technology, called VideoVitals, uses a combination of photo-plethysmography and computer vision to detect heart rate based on minute skin color changes. The computer vision helps to account for differences in environmental lighting, skin pigmentation, and camera quality, and to complete a measurement even when the subject is moving.” MORE
