METHOD AND SYSTEM TO ESTIMATE DAY-LONG CALORIE EXPENDITURE BASED ON POSTURE
First Claim
1. A method comprising:
- obtaining, by the fitness tracking device, motion data of the user over a period of time, wherein the motion data comprises a first plurality motion measurements from a first motion sensor of the fitness tracking device;
determining, by the fitness tracking device, using the motion data an angle of the fitness tracking device relative to a plane during the period of time;
estimating by the fitness tracking device, using the motion data, a range of linear motion of the fitness tracking device through space during the period of time; and
comparing, by the fitness tracking device, the angle of the fitness tracking device to a threshold angle and comparing the range of linear motion of the fitness tracking device to a threshold range of linear motion to determine whether the user is sitting or standing.
