Amazon’s radar sensors could help Alexa monitor your sleep patterns

FCC waiver will let Amazon make devices that track how you move in your sleep

Amazon is interested in using radar sensors to enable sleep tracking and gestures on its smart devices, according to new permissions Provided by the Federal Communications Commission (Via bloomberg) implementation could be similar to the way Google uses its Soli sensor in the second-generation Nest Hub.

Amazon’s initial request filed June 22 for the FCC (and dug by slashgear) claims that its planned use of radar will enable “touchless control of device features and functions without harmful interference to co-frequency users”, which may be helpful for users with limited mobility or speech impairment. The company also says that the new sensor “could be used for sleep tracking and could help improve consumers’ awareness and management of sleep hygiene.”

Rumors first emerged in January that Amazon was manufacturing a “palm-sized” Alexa-enabled sleep tracker with a specific focus on tracking breathing for users with sleep apnea. The company already digests and displays sleep data for anyone using its Halo band (the one with the precise but problematic body scanning feature). Amazon is expanding on the capabilities of the Helo app with a new Movement Health feature that analyzes flexibility that was released last week.

Amazon’s request didn’t specify what an actual product with these new radar sensors might look like, but adding them to future Echo devices doesn’t seem like much reach, considering how many of them are on the bedside table. fit comfortably. In its Nest Hub, Google’s Soli radar sensors track sleep movements and breathing, along with a microphone and an onboard temperature sensor. Making a purchase means allowing Google, and maybe one day Amazon, to stare at you all night, but in a way it’s less invasive than a camera feed or wristband.
