Our HiBall Tracking System generates over 2000 head-pose
estimates per second with less than one millisecond of latency, and
less than
0.5 millimeters and 0.02 degrees of position and orientation
noise, everywhere in a 4.5 by 8.5 meter room. The system is remarkably
responsive and robust, enabling VR applications and experiments that
previously would have been difficult or even impossible.
Previously we published descriptions of only the Kalman
filter-based software approach that we call Single-Constraint-at-a-Time
tracking.
In this paper we describe the complete tracking system,
including the novel optical, mechanical, electrical, and algorithmic
aspects that enable the unparalleled performance.
