ABSTRACT:
A signal transmitting and receiving system to track the position and orientation of limb segments in order to provide feedback information for the control of the limb movement. The user will generally be seated in a wheelchair that provides a structure upon which orthogonal and/or non-orthogonally oriented coils can be mounted and energized selectively so as to create variously oriented magnetic fields. Multiple wireless sensors injected into the limb detect the local field strength and send information telemetrically to a central controller. The controller extracts information about the position and orientation of each limb segment by combining signals from various sensors according to calibration information and optimal filtering methods for extracting information from multiple nonlinear sensors in mechanically constrained systems.
