Flight safety demonstration and infotainment through mixed reality

An aircraft system comprising:

• a head-mounted display within an aircraft environment, the head-mounted display including;
• a frame;
• at least one camera fixed to the frame and configured to generate a first video signal corresponding to images captured of the aircraft environment;
• a head tracker fixed to the frame and configured to generate pose information indicative of a position and orientation of the at least one camera;
• a display fixed to the frame and configured to generate an image;
• an avionics network;
• and
• a processor communicatively coupled to the head-mounted display by the avionics network, the processor configured to execute program instructions maintained on a memory causing the processor to:
• receive the first video signal and the pose information from the head-mounted display by way of the avionics network;
• detect a feature vector within the first video signal by digital image processing the first video signal using a feature detector algorithm, the feature vector including at least a first feature corresponding to an aircraft safety device including one of a life preserver stowage, an oxygen mask passenger service unit, a seatbelt, or an emergency exit door;
• estimate a pose of the aircraft safety device within the first video signal based on the feature vector together with the pose information from the head tracker;
• generate a second video signal by compositing the first video signal with one or more virtual objects corresponding to a safety instruction associated with the aircraft safety device, the one or more virtual objects positioned and oriented within the second video signal from a perspective of the head-mounted display based on the pose of the aircraft safety device;
• and
• cause the display of the head-mounted display to display the second video signal.
