Abstract :
Motion tracking capabilities of a head-mounted accelerometer apparatus were investigated in conjunction with three-dimensional motion analysis techniques during activities of daily living. In this report, measures between systems are compared for jogging, toe-touching, and start-from-rest tasks. Good fidelity was found for most measures between systems; some phase shifts and amplitude discrepancies were observed, and attributed to transducer orientation and system asynchrony. This preliminary work demonstrates the potential benefits of hybrid motion analysis systems.
