- Google has unveiled new features, which will allow iPhone users to measure their heart and breathing rates using its camera.
- For measuring heart rate, users need to place a finger on the camera
- Users apparently do not need an active internet connection to make the feature work.
Google revealed its upgraded version of the Fitness app. Now, Google’s Pixel phones will soon be able to track heart rate and respiratory rate using just the camera. Currently, this feature is only available to Pixel phones. The company is planning to expand this feature to iOS devices.
Google Fit is now adding the same capabilities on iOS, allowing iPhones to get the feature as well. Google Fit for iOS has also received another interesting update that will help users keep a track of the number of breaths they take.
How does it work?
Heart rate measurements start by placing your finger on the rear-facing camera lens and applying light pressure. There’s the option to turn on flash to increase accuracy in dark environments, or you can place your hand in front of a light source.
Google is tracking the “subtle changes in the color of your fingers” to approximate blood flow, with the heart rate algorithms accounting for lighting, skin tone, age, and other factors. Additionally, it works offline with no internet connection required. This takes about 30 seconds with a preview graph and BPM noted at the bottom of the screen. Once complete, you can decide whether or not to save the vitals to Fit.
In order to measure your heart rate, all you have to do is hold your finger over your Pixel phone’s rear camera lens and apply a little bit of pressure. The Google Fit app will detect the pulse in your fingertip to measure your heart rate.
In order to measure the respiratory rate, you’ll have to keep your smartphone on a stable surface and then sit still in its view. Start breathing and let the camera watch your chest movements to detect your respiratory rate.
The results are then shown on the app, which can be saved for later diagnosis.
For better results:
- Google recommends that if you’re wearing masks or hats, they should be removed for accurate results.
- If you’ve just finished a vigorous physical activity, you should take some rest and return your breathing to a normal level before taking the reading.
