Abstract:
An electromagnetic tracking system includes a hand held controller including an electromagnetic emitter configured to generate an electromagnetic field characterized by an electromagnetic field pattern and a first electromagnetic reflector positioned adjacent the electromagnetic emitter and configured to form a modified electromagnetic field pattern. The electromagnetic tracking system also includes a head mounted augmented reality display including an electromagnetic sensor configured to sense the electromagnetic field and a second electromagnetic reflector adjacent to sensor configured to optimally sense electromagnetic field pattern in a region of interest.
