Abstract: Head wearable display (HWD) systems and methods of display reliability verification with respect to the HWD operated by a user are provided, which comprise tracking a position and orientation (P&O) of the HWD relative to hardware element(s) at known position(s), which are selected from a surroundings of the user and are visible to the user through the HWD, calculating position(s) of the hardware element(s) with respect to the HWD, and displaying, in the HWD and according to the calculated position(s), verification symbol(s) that correspond to the hardware element(s). Display reliability verification may be carried out automatically using a camera and an image processing module, optionally with an additional illuminator, which compares the element(s)'s captured locations with the element(s)'s expected location according to the tracking, and indicates possible discrepancies. Discrepancy identification may be used to initiate a correction process or to indicate the presented symbology to be unreliable.
