Smartphone or computer cameras now measure pulse, respiration rate to aid future personalized tele-health appointments

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.

A University of Washington-led team has developed a method that 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. The researchers presented this state-of-the-art system in December at the Neural Information Processing Systems conference.

Now the team is 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. The researchers did present these findings April eighth at the ACM Conference on Health, Interference, and Learning.

Keeping your smartphone nearby may not be so smart – Harvard

I am an Apple fanboy and have owned an iPhone for years. I do rely on it very much.

I love the convenience of the machine as well as the power of having a little computer at my fingertips when I travel. It appears that there is a downside to Steve Jobs’s little godsend, though, according to Harvard Health Publications.

Imagine you were asked to complete a series of math problems, ones just hard enough to require your attention and focus, but nothing you couldn’t handle. Now, imagine you were intermittently interrupted from these math problems and asked to remember a random list of letters. This might be even tougher. Continue reading
