Abstract
A head-mounted display system includes a left display assembly configured to provide left-side display light. A first left inertial measurement unit (IMU) is configured to measure an orientation of the left display assembly. A right display assembly is configured to provide right-side display light. A first right IMU is configured to measure an orientation of the right display assembly. A communication interface is configured to receive a left-side orientation of a head-tracking system as measured by a second left IMU, and a right-side orientation of a head-tracking system as measured by a second right IMU. A logic machine is configured to assess an alignment of the head-mounted display system based at least in part on the orientation of the left display assembly, the orientation of the right display assembly, the left-side orientation of the head-tracking system, and the right-side orientation of the head-tracking system.
