METHOD AND SYSTEM UTILIZING PHASED ARRAY BEAMFORMING FOR SIX DEGREE OF FREEDOM TRACKING FOR AN EMITTER IN AUGMENTED REALITY SYSTEMS

摘要

An electromagnetic tracking system includes a handheld controller including a first phased array element characterized by a first phase and a second phased array element characterized by a second phase different than the first phase. The first phased array element and the second phased array element are configured to generate a steerable electromagnetic beam characterized by an 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 pattern.
