The point of doing this is to help keep the user motivated on their fitness regimen by enabling them to accurately monitor and track how their body is changing as they get in better shape. This method closely mirrors hydrostatic testing, which determines your body fat percentage based on how much water you displace. It is far more accurate than the bioelectrical impedance method used by Fitbit's Aria scale, for example, Naked Labs founder and CEO Farhad Farahbakhshian claimed during a recent product demonstration.
Now don't freak out just because these models resemble the TSA's backscatter images: The company has gone to great lengths to anonymize and secure people's personal biometric data (plus you can always just wear shorts). The models have been given grey skin on purpose because, as Farahbakhshian explained, it provides a "truer" view of the user's body than they'd get with the room's natural lighting. Naked Labs also stores and transmits all user data through AES 256-bit encryption and its app allows users to dictate exactly who can see that data. This way, for example, you can share your progress with your doctor or personal trainer if the need arises.
There are some limits to what the system can do, however. Users over six-foot-nine for instance will have to make do with a slightly lower resolution scan since they'll have to position the rotating scale farther away from the mirror to fit all of themselves within the sensors' fields of view. That said, the drop in resolution should be minor, Farahbakhshian assured me. The scale set is available for pre-order starting today. The company expects to ship units by March 2017.
