Scientists developed Artificial intelligence that can calculate breathing and heart rate from smartphone data

Experts from the University of Washington and the Microsoft Research Laboratory have developed software capable of monitoring certain human vital signs. It involves using artificial intelligence (AI) to analyze heart rate and breathing from video recordings. The results of the work are presented at the ACM CHIL 2021 conference, reports The Engineer.

The system captures subtle changes in light reflections from a person's face caused by various physiological processes and then converts this data to estimate heart rate and respiration rate. Scientists believe that an ordinary smartphone camera is sufficient for accurate and high-quality analysis. 

At the moment, engineers have improved machine learning algorithms and now the AI is able to take into account a person's individual characteristics, background, and ambient light. However, scientists admit that there are still problems when working with darker skin tones.

The researchers are actively cooperating with doctors and several clinics in the U.S. are already testing the beta version of the new monitoring technology. Senior author Svetak Patel, a professor at the Allen School and the Department of Electrical and Computer Engineering, believes that the ability to determine heart rate and respiration rate in a simple and accessible way will help patients monitor their own health and well-being.
