Human footstep detection using proximity compensation algorithm withaccelerometer and time of flight sensor

摘要

This paper is about an innovative and robust way to count human footsteps using accelerometer and proximity sensor (time of flight). The proximity compensation mechanism along with motion detection by accelerometer ensures to prevent false step detection. This solution can be used for smart shoe. Any shoe attached with this kind of solution will be smart enough to detect your step and calorie counts. When proper motion pattern is recognized by accelerometer, the time of flight sensor, on proximity to the ground, will detect a real step. Also this type of solution is going to help all those OEM/ODMs, who have introduced fitness bands for promotional purpose and providing rewards to the end user on daily/weekly step limit accomplishment.
