Drift-Free Foot Orientation Estimation in Running Using Wearable IMU

Kamiar Aminian, Frédéric Meyer, Benoît Mariani, Grégoire Millet, Mathieu Pascal Falbriard

This study aimed to introduce and validate a new method to estimate and correct the orientation drift measured from foot-worn inertial sensors. A modified strap-down integration (MSDI) was proposed to decrease the orientation drift, which, in turn, was fur ...
