How does the Oura Ring monitor and calculate the number of steps taken by a user?

The Oura Ring is equipped with a 3D accelerometer, which it uses to monitor the user's physical activity including the number of steps taken. When the user moves, the accelerometer measures the direction and intensity of the movement, and sophisticated algorithms analyze the motion data to distinguish between different types of activity and to count steps. These algorithms are designed to recognize the repetitive pattern characterizing walking or running as distinct from other movements and accurately calculate steps taken. The Oura Ring processes this information in conjunction with its analysis software, translating raw data into understandable metrics about the user's daily activity levels, which are then relayed to the user through an accompanying app for easy monitoring and review.
