ã€Global Science and Technology Report】 According to the British "Daily Mail" reported on May 10, recently, Apple acquired the sleep monitoring company Beddit. The Beddit Sleep Tracker is a device that monitors the user's sleep status and can generate data reports to help users rest better. It is speculated that Apple may apply sleep tracking technology to the upcoming WatchOS 4. Sleep tracking has always been a hot technology in the technology community. Many wearable devices provide this functionality for users. As a wearable device that reached the top of sales in the first quarter of this year, there is no doubt that the expansion of Apple Watch's functions in addition to fitness is imminent. Recently, sleep monitoring company Beddit stated in the latest privacy policy that the company has been acquired by Apple. In the future, personal data of users will be collected and used in accordance with Apple's privacy policy. The Beddit Sleep Tracker was unveiled in 2014 and features a built-in sensor that monitors the user's heartbeat, breathing, snoring frequency and quietness in the bedroom, generates comprehensive data and sends it to the phone via Bluetooth. At present, Apple Watch is mainly used to calculate calorie consumption, steps, breathing and heart rate, but has no sleep monitoring function. Previously, users did not pay too much attention to the lack of sleep tracking function, because they generally remove the watch when they are sleeping. In fact, users only need to spend half an hour to fully charge the device, and wearing a full night is not a problem. In addition, Apple also revealed that the upcoming sleep tracking software can also monitor the user's respiratory status and publish the data to the health platform Healthkit.
