Using the accelerometer to track the speed and direction of motion when asleep to measure sleep quality is known as actigraphy.

Most wearable fitness trackers come equipped with a function known as “Sleep Mode.” The user must activate this mode on the gadget for the data to be compiled accurately for the time that they are asleep. How Does a Wearable Fitness Tracker Know When You’re Asleep? This information is then produced as output for the individual to view and make more informed decisions about their fitness regimen. Trends can be established based on the history of the individual’s data available. This is how the individual is able to track the day’s exercise, heart rates, and even sleep patterns. The software uses complex algorithms to sort the data it has received into useful information which will make sense to the user. This happens when the gadget is synced to the smartphone or laptop. This data is then transferred to the smartphone or laptop to which the fitness tracker is linked. The sensors on the tracker keep account of all the input that they receive. Most modern fitness trackers are worn by the individual on the wrist in place of a wristwatch or around the waist. This data is then processed with algorithms to make more sense of the movements. The majority of them have three axis accelerometers which allow them to monitor just how fast an individual moves in any direction. ![]() A number of new fitness trackers that link up to a smartphone or a laptop are available in the market today.
