Basis Science, the company behind the Basis B1 fitness band, has released an update they’re calling the Basis Carbon Steel Edition. The new model is more of a refresh than a whole new device. It features the same hardware package and basic design, but adds new steel and polished chrome accents, along with a new silicone band. The design now accepts normal watch bands, so wearers can customize it however they please.
Alongside the launch, Basis is revealing a new feature for its platform, Advanced Sleep Analysis. Previously, Basis’ software tracked overall sleep duration by using its various sensors to determine when a wearer’s body was in a rest state. Using the BodyIQ suite of algorithms and analysis, Basis now claims to be able to detect the three sleep states (REM, Deep, and Light) as well as when you’re tossing and turning or are interrupted.
Competitor Fitbit currently measures sleep quality based on movement. Each large movement overnight is counted as time spent awake, and at the end of the night the time spent sleeping is divided by how long you were in bed. The ability of the Basis Carbon to determine sleep states takes advantage of research done in conjunction with a team that includes the University of California-San Francisco and emphasizes motion data along with heart rate to determine each sleep state. Validation of the results was conducted by Basis’ research partners and leaves the company confident that BodyIQ sleep analysis is as close to medical-grade devices as any commercial device on the market.
