Abstract
An inertial head-tracking system includes light emitting diodes (LEDs) and photoreceptors. The LEDs and photoreceptors are positioned around the environment and helmet respectively. A processor periodically receives measurements from the photoreceptors and resets inertial drift based on those measurements. Either the LEDs or the photoreceptors are constrained to a specified range to allow for more accurate drift estimation.
