Walking: Foot Progression Angle Feedback [Download]

Written By SageMotion

About

This App is for measuring and training foot progression angle changes during treadmill or overground walking

This algorithm is based on the Tan2020 magnetometer-free FPA algorithm paper [1] and only uses accelerometer and gyroscope data thus avoiding magnetic disturbance. Heading direction is determined based on the max acceleration direction of the foot before heel strike.

Nodes Required: 3
Sensing (1): foot (top, switch pointing forward)
Feedback (2): foot_medial, foot_lateral
