Google adds heart, breath reading app to latest smartphone

Users of Cameras on Google Pixel smartphones will,  from next month, enjoy the functionality of measuring heart and breathing rates from a new app to be added to the phone. The app is one of Google’s applications of Alphabet Inc’s artificial intelligence technology added its wellness services.

Health programmes available on Google Play’s store and Apple Inc’s App Store for years have provided the same functionality. But a study in 2017 found accuracy varied and adoption of the apps remains low.

Google Health leaders told reporters earlier that they had advanced the AI powering the measurements and plan to detail its method and clinical trial in an academic paper in the coming weeks. The company expects to roll out the feature to other Android smartphones at an unspecified time, it said in a blog post on Thursday, but plans for iPhones are unclear.

Apple’s Watch, Google’s Fitbit, and other wearable have greatly expanded the reach of continuous heart rate sensing technologies to a much larger population.

The smartphone camera approach is more ad hoc – users who want to take a pulse to place their finger over the lens, which catches subtle color changes that correspond to blood flow. Respiration is calculated from a video of upper torso movements.

Google Health product manager Jack Po said that the company wanted to give an alternative to manual pulse checks for smartphone owners who only want to monitor their condition occasionally but cannot afford a wearable.

Po said the technology, which can mistake heart rates by about two percent, requires further testing before it could be used in medical settings.

The new feature will be available as an update to the Google Fit app. The company consolidated its health services about two years ago, aiming to better compete with Apple, Samsung Electronics Co and other mobile technology companies that have invested heavily in marketing wellness offerings.
