Google pumps up health tracking with camera tech

Google prepared to rollout a new feature for its Fit app which will allow users to measure their heart and respiratory rates using a smartphone camera, a move it insisted didn’t conflict with its recent $2.1 billion acquisition of wearables company Fitbit.

In a blog, Google explained computer vision technology enabled smartphone cameras to “track tiny physical signals at the pixel level”, including colour changes in a user’s fingers to measure heart rate and chest movements for respiratory rate.
