Abstract: In one aspect, a computerized process useful for managing a hybrid motion sensing framework includes the step of providing a motion capture framework worn by a user to measure a user posture and motion by measuring an external source signal and an inertial property of the motion capture framework. The motion capture framework comprises a set of motion sensing units (MSUs) and an electromagnetic field generator (EFG). The MSU is a hybrid sensing system using a combination of sensors to measure position and orientation. The EFG generates an alternating electromagnetic field with a specified frequency. The method includes the step of calculating the user posture and motion based on the measuring an external source signal and an inertial property of the motion capture framework using a sensor fusion algorithm. The method includes the step of visualizing the position and orientation of the user.
