The good news for smartphone users is that heart rate and respiratory rate, two of the most important indicators of health and fitness, can now be monitored via a smartphone.
Google has announced that these features will be available in the Google Fit app for Pixel phones from next month.
Smartphone cameras and computer vision techniques, called optical flow, are used to measure the speed of breathing, while a smartphone camera detects changes in your fingers when your heart beats to see the heartbeat. Fresh oxygenated blood flows through your body.
With this new technology, Google Fit will allow you to measure your heart rate and respiratory rate using your smartphone camera.
According to Shivtak Patel, Director, Google Foot Health Technologies, the feature will be available in the Google Fit app for Pixel phones, which is being rolled out to more Android devices.
According to Shivatak Patel, to see the pulse rate, you have to place your head and upper body in front of the front camera of the smartphone and breathe, while you have to place your finger on the rear camera lens to know the heartbeat.
