This is a "display on your eye", not Augmented Reality. Nothing is mentioned on solving the real problems of rendering perspective correct imagery layered over the real world, adjusting for head movement, saccades, microsaccades, gait, movement of vehicles, etc.

This is what Google Glass isn't even trying to do.

Modern airliners have HUDs that display "perspective-correct imagery layered over the real world". It's useful for landing in the fog.

Airliners have almost none of the problems the OP mentioned. The displays are several feet away from the movement of the eye. Movement of the sensors is slow and smooth. The target distance is near infinity in optical focus. The overlayed target is a generally a giant flat rectangle. These are some delicious simplifying assumptions.
