A personal healthcare system for contact-less estimation of cardiovascular parameters

Conventional methods for measuring cardiovascular parameters use skin contact techniques requiring a measuring device to be worn by the user. In this work we propose an innovative solution for monitoring cardiovascular parameters that uses a contact-less device and can be easily integrated within home environments. The proposed system is a smart device composed of a see-through mirror equipped with a camera that captures the person's face and provides a real-time estimation of the heart rate and the oxygen saturation using photoplethysmography. Compared to a contact device in measuring vital parameters on still or slightly moving subjects, our solution achieves measurement errors that are within acceptable margins according to the literature.
