1. An electromagnetic tracking system comprising:
a handheld controller including an electromagnetic emitter, the electromagnetic emitter 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 wherein 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; and
a head mounted display including an electromagnetic sensor configured to sense the electromagnetic field pattern;
wherein the electromagnetic tracking system is configured to:
control the first phase and the second phase to steer the electromagnetic beam to increase received power at the electromagnetic sensor; and
determine a pose of the handheld controller relative to the electromagnetic sensor using the electromagnetic field pattern sensed at the electromagnetic sensor.
