Abstract
A system includes a vehicle cockpit and a processor. The vehicle cockpit includes imperceptible cockpit reference fiducials and a head wearable display (HWD) device. The imperceptible cockpit reference fiducials are imperceptible to a naked eye of a user in the vehicle cockpit. The HWD device includes a display and an optical sensor configured to: capture images of the imperceptible cockpit reference fiducials; and output optical sensor image data. The processor is configured to: receive the optical sensor image data; and based at least on the optical sensor image data, determine a position and orientation of the head wearable display device. The display is configured to display the images aligned with the field of view of the user based at least on the determined position and the determined orientation of the head wearable display device.
