US Patent 11504554 Facemask-mounted augmented reality display for extravehicular mobility unit

A facemask-mounted augmented reality (AR) display device is disclosed. In embodiments, the display device is hard-mounted to a breathing apparatus (e.g., oxygen mask, smoke mask) fitted to a user's nose and mouth behind a partially or fully covering external face shield. The AR display system includes display surfaces aligned with the eyes of the user and capable of providing the user with a forward field of view that moves with the user's head. The AR display system synthesizes streaming images with additional overlay sources (e.g., mission data, position data) to generate augmented reality content presented to the user within the field of view of the display surfaces.
