A wearable tracker continuously senses the movements of the body on a 3 axis accelerometer. The data is recorded all the time it is worn and powered up, which enables the tracker to trace if the individual is walking forward, running fast, or even standing still.
All this data is stored in the tracker for further processing. Processing occurs when the data is transferred to the software associated with the fitness tracker on the smartphone or laptop with which it is synced.
Since the individual has already shared personal details with the software, the data collected is run through a personalized algorithm. This makes it possible for the software to detect what the different movements recorded actually imply.
It categorizes the movements into different activities and then generates more information based on these details. These are usually stored under different headings in the fitness tracker app.
When the individual taps the app a wide variety of information is available from the processed data, ready for reading. The app lets the individual know how many steps have been taken, at what speed, the pace of the individual, and even the number of calories likely to have been burnt. The app allows the individual to interact with the information in a user friendly manner.
