Step Counting Using Smartphone-Based Accelerometer

This paper presents a method for counting the number of steps taken by a user, while walking at any variable speed, using Smartphone-based accelerometer. For this purpose, the steps are detected based on a relation between frequency of step, which varies inversely with speed of motion, and the magnitude of accelerometer signal. The pattern of the forward acceleration was observed to arrive at the final relation. Step detection is the automatic determination of the moments in time at which footsteps occur.
