Abstract
A multi-dimensional tracking sensor for tracking a moving transmitter with particular applications in virtual reality and other real time computer applications. The system employs an electro-magnetic (EM) tracking sensor having a small lightweight transmitter with a transmitting antenna located on the target to be tracked and an array receiver with several local stationary antenna elements. Multiple antenna elements of the array receiver lie on the perimeter of the measured space in positions determined by a self-calibration procedure. The proposed device calculates a cross correlation function between two signals at each receiving unit to determine a spatial position of the tracked element via a system of linear equations.
