- •
Foot trajectory during walking was estimated using an IMU sensor attached to the foot.
- •
Zero velocity and displacement corrections were applied to calculate the trajectory.
- •
Foot clearance was estimated more accurately than with previously published methods.
- •
This system serves as a useful tool to monitor human walking during daily activities.
