A new method uses the camera on a person’s smartphone or computer to take their pulse and respiration signal from a real-time video of their face. Telehealth has become a critical way for doctors to still provide health care while minimizing in-person contact during COVID-19. But with phone or Zoom appointments, it’s harder for doctors to get important vital signs from a patient, such as their pulse or respiration rate, in real time. With their new method, researchers are proposing a better system to measure these physiological signals. This system is less likely to be tripped up by different cameras, lighting conditions, or facial features, such as skin color.
