Google announced last month that the Goole Fit application will support the use of mobile phone cameras this month (March) to detect the user's breathing rate and heartbeat rate.
Take a picture of your upper body with the front camera to quickly detect the respiratory rate. To detect the heartbeat frequency, just put your finger on the rear camera.
Are you a little surprised? We know that many smart watches support heartbeat detection, but they are all equipped with a professional heart rate sensor. Didn’t expect that the phone camera can also detect it?
Google said that thanks to the advancement of cell phone camera sensor technology and computer vision technology, cell phone cameras can already capture very subtle physical changes, down to the pixel level. By detecting the slight movement of the rib cage, you can know the breathing rate, and by detecting the subtle color changes of your fingers, you can know the speed of your heartbeat.
Goole Fit is a health detection and recording app developed by Google. It can run on iOS and Android systems. This feature will first support Google's own pixel phones, and will be expanded to other models in the future.
