Google can use the Pixel’s cameras to pull out health signals by detecting tiny fluctuations in skin color and movement.
Heart and respiratory rate tracking is nearly ubiquitous on sleek fitness bands and bulbous smart rings. Where those kinds of metrics are not yet universal is on smartphones. On Thursday, Google announced plans to change that by launching new software that can capture your heart rate and breathing rate through your phone’s camera lens. The technology will be rolled out inside of Google Fit, the company’s health tracking platform, on Pixel phones.
