Amazon Halo will use your smartphone camera to assess your ‘Movement Health’

From The Verge: Soon, Amazon’s Halo fitness service will offer to use your smartphone’s camera and some cloud-based AI to create a scan of your “Movement Health.” After a five- to 10-minute session where you put yourself into different poses for the camera, Amazon’s servers will analyze the video and use it to create a customized workout routine to improve your “stability, mobility, and posture.” The service is expected to launch “in the coming weeks.”

As with Halo’s body fat scan, Amazon says that the video it records for Movement Health is sent to its cloud servers, analyzed only by its algorithms (and not humans), and is then promptly deleted both from the cloud and from your phone. The videos are encrypted in transit and when they’re (briefly) at rest in Amazon’s cloud. The Halo fitness band isn’t used in any particular way during the scan.

After the scan, you’ll get a readout like the image you see above, which breaks down the mobility of your body in terms of percentages — presumably percentages of the ideal range of movement. Njenga Kariuki, senior technical product manager for Amazon Halo, says that its machine learning algorithms were created with a diverse set of bodies:

"We take a responsibility to ensure that our algorithms deliver comparable performance across demographics and body types and we extensively test different dimensions across things like body types, different ethnicity groups, a number of different demographic dimensions."
