Google and Fitbit are developing sleep tracking capabilities in the Fitbit, Pixel Watch, and Nest Hub (2nd generation) devices that use artificial intelligence to analyze your movement, heart rate, and sleep stages, and then combine all of this information to provide you with detailed information data. on your sleep habits.
Here are 5 AI features in Google devices to help you sleep better:
1- Sleep tracking function:
Sleep-tracking algorithms on the Pixel Watch and Fitbit devices look for movement patterns and changes in your heart rate to determine what stage of sleep you're in and for how long.
The sleep tracking algorithm works by combining several algorithms at once, one of which detects the time between each heartbeat by monitoring the signals reflected from the wrist. Others detect your movements by tracking your device's accelerometer (motion sensor).
This information is sent to Fitbit's cloud, where machine learning algorithms combine heart rate and motion information to estimate what stage of sleep you're in and when sleep starts and ends.
2- Sleep Score function:
Sleep tracking creates your sleep score, which is a number between 0 and 100 that you get each morning. This metric is the first thing you see when you check last night's sleep in the Fitbit app.
The degree of this depends on how long you sleep, what percentage of deep sleep you go through, and what stage (rapid sleep) REM sleep you're in. AI technology analyzes this information to give you a sleep score for each night.
3- Smart Wake function:
Your Fitbit's Smart Wake feature, which prevents you from waking up when you're in a deep sleep stage, relies on measuring your movement and heart rate in response to deep sleep and when those rates start to differ, the Fitbit sleep algorithm, the Fitbit app knows. Now is the time to start your wake-up call.
When Smart Wake is enabled, you can set the alarm time and the alarm will wake you up to 30 minutes after that time, depending on when you woke up from a sound sleep. The alarm vibrates very gently to gently wake you up without making it too loud.
4- Sleep Sensing function:
The Nest Hub (2nd generation) has Sleep Sense, which uses Motion Sense, low-power radar, sound, light, and temperature sensors to detect nocturnal motion and breathing patterns, as well as light and temperature changes in a room. It can affect your sleep, all of this data is processed in the device according to algorithms that analyze the data collected by the sensors. In the morning, Sleep Sensing analyzes your sleep from the previous night.
5- Sleep file function:
Sleep Profiles, which is available on Fitbit devices and the Pixel Watch, requires a Fitbit Premium subscription and records at least two weeks of sleep data so it can see what typically happens while you sleep, and then give you a comprehensive analysis at bedtime. situation.
