Abstract
Networks of Wireless Inertial Measurement Units (WIMUs) allow for the real time capture of orientation data from multiple devices. Combining data from WIMUs with a rigid body model allows estimation of subject posture. However, posture information is not sufficient for full-body motion capture, the position of the subject in space must also be tracked. In this paper we examine the problem of relative position tracking; provide a demonstration of a novel location estimation algorithm, based on probabilistic ground contact detection; and discuss the use of aiding technologies.
