Smartphone Camera to Monitor User's Vital Signs on Research

Researchers at Rice University try for further technique to find health-tracker application for smartphone and computers based on user's skin color. A new algorithm is developed to detect skin tone variation caused by blood circulation to determine pulse and breathing rates.

A way to measure physiological processes under user skin monitors changes at the skin surface, known as photoplethysmography (PPG), using a camera to track vital signs.

The PPG signal is extracted from four regions marked on the face

The algorithm, called DistancePPG, is measuring the eyes, nose, and mouth separately. Vital signs are estimated by the average of blood perfusion and incident light intensity.

However, it remained relatively inaccurate when user were moving, even talking and smiling. These movements changed the facial light and difficult to detect user signal, as said by researchers.
