Inertial Motion Tracking for Inserting Humans into a Networked Synthetic Environment

摘要

Inertial/Magnetic tracking is based on the use of sensors containing three orthogonally mounted angular rate sensors, three orthogonal linear accelerometers and three orthogonal magnetometers to determine independently the orientation of each link of an articulated rigid body. Inertial/magnetic orientation tracking could be applied to a broad range of problems which require real-time tracking of an articulated structure without being continuously dependent upon an artificially generated source. This research focuses on the goal of developing and demonstrating wireless full body tracking using MARG sensor modules. During the period of this report, six manuscripts were submitted for peer-reviewed publication. Of these six, five have been accepted. These include three journal publications and two conference papers. In additions, scientific advances have been made in the following areas: * Study of the Magnetic Effects on Inertial/Magnetic Sensor Modules * Development of a singularity free Factored Quaternion Algorithm * Development of an advanced Kalman Filter for Inertial/Magnetic Body Tracking *Initial development in using inertial/magnetic sensors for position tracking.
