The smartphone industry is consistently developing. Every day, we get to see one new feature or another in the market. According to the latest reports, Google will soon add some interesting features to the Fit application of its Pixel smartphone. Users of the Google Pixel phone will be able to measure their heart rate by placing their fingers on the rear camera.
The report shows that this feature will track the heart rate by tracking the colour change of the blood. This tracking is only possible when the fingertip moves. This means that users will probably not just place their fingers on the camera. They will have to move the finger slightly for effective measurement. This is the basic working principle of this feature.
There is also a new function to measure the user’s breathing rate, which is done through a selfie camera. The user only needs to place himself in the viewfinder of the Google Pixel phone camera and then just breathe. The software monitors the ups and downs of the user’s chest and infers the breathing rate based on this.
A product manager of Google Health explained that doctors also use the same method to calculate the patient’s breathing rate, and the company’s machine learning technology imitates this method.
Google PM said: “Many people, especially those with poorer economic conditions, do not have such things as wearable devices, but if they can track their breathing rate, heart rate, etc., they will still benefit.”
According to Google’s internal research, the error of the respiratory rate function is within one breath per minute. This means that it will be applicable for users with or without health conditions. The heart rate reading error is within 2%. These features have been tested on people of different skin tones, and the accuracy rates are similar.
We understand that these features may be applied to non-Pixel phones in the future, but Google must first study how effective they are on its devices.
