Abstract

A hybrid tracking system utilizing at least one combined light emitting diode (LED) and magnetoresistance sensor. The hybrid tracking system includes optical tracking technology and electromagnetic (EM) tracking technology with at least one combined LED and magnetoresistance reference sensor attached to a fixed object, at least one combined LED and magnetoresistance sensor attached to an object being tracked, and a processor coupled to the at least one combined LED and magnetoresistance reference sensor and the at least one combined LED and magnetoresistance sensor for processing signals from the at least one combined LED and magnetoresistance reference sensor and the at least one combined LED and magnetoresistance sensor. The combined LED and magnetoresistance sensor includes at least one magnetoresistance sensor and at least one LED that are integrated into a single package.
