Kevin Lynch, Apple’s vice president of technology, said in an interview that sleep tracking has been an intentional feature of Apple Watch for the past five years, and that its inclusion in watchOS 7 and iOS 14 is a sign that The company wants to do more with years of research in this area,media reported.
As a long-rumoured feature of the Apple Watch, the new sleep-related feature is intended to encourage users to develop a daily habit before bedby by minimizing distractions. While this is an extension of Apple’s existing Bedtime feature in iOS, it has been in the works for some time from simple sleep time metrics to more advanced features.
In an interview with CNET, Lynch confirmed that sleep-tracking has been on the product roadmap since the Apple Watch was first unveiled. Apple has been conducting sleep research for years, including using an electroencephalogram to measure sleep compared to the Apple Watch, but it has only now become a bigger thing for Apple to show users.
Regarding the Wind Down feature, which helps set the pre-bed time routine, Lynch explains that establishing routines is important for sleep quality: “Many sleep applications display information about REM cycles and other similar data, and we’ve looked at a lot. “
While the use of eEG scans allows monitoring of brain electrical activity during sleep, Lynch acknowledges that “we’ve learned a lot about the main things here that really matter about duration” rather than actions. While limb movements can be used as inputs for monitoring through the Apple Watch, Lynch says “it doesn’t fully reflect what’s going on inside your brain.”
Apple’s decision to limit the amount it provides to users is based on the results of these studies, and it does not provide users with seemingly useful data. “Looking at the data can be overwhelming and stressful,” he advises on tracking the results of the sleep analysis app. “You can’t really guide yourself to have more or less REM stages. “
Apple doesn’t think this is the best way to do it, but rather seehow users getting ready to sleep as a more actionable process. Routine habits “will allow people to get better sleep and then have a secondary effect, perhaps your REM phase will organize itself.” To further eliminate the stress that needs to improve sleep, tracking in health apps avoids negative emotions to influence users, but rather chooses positive reinforcements whenever possible. Sleep anxiety “actually leads to more problems,” Lynch said, adding that people “already know they’re not getting enough sleep.”
Like the Apple Watch and other health-related elements elsewhere, Apple doesn’t plan to see any sleep data generated by users. Internal research relies on “thousands” of people and plays an important role in creating machine learning models for analytics that are done only on users’ iPhones or Apple Watches.
“We treat the data collected on users’ devices with a high degree of privacy sensitivity,” Lynch said. Even so, apple has always had the potential to open up some form of public research on sleep, similar to its existing heart and hearing program, possibly to determine the link between sleep-related conditions.
