Abstract :
This paper proposes a method for estimating the movement of a user using an acceleration sensor called UME (user movement estimator). By considering time-axis changes in the power spectrum, the method is able to avoid performance loss due to factors such as sudden vibration or times when the power spectrum resembles different types of movement. Testing results show that the method has significantly better performance than past methods.
