It's not a HUD it's a HMD or "Head or Helmet Mounted Display". It
belongs to a subset of these devices called "retinal display" which
projects a perfectly focused image onto your retina using microwatt
lasers which eliminates any presbyopia problems the user might have
and keeps the display in sharp focus regardless of where the user's
eye is focused. The "See Through" feature causes the projected image
to be overlaid on a real world view. The brightness is high enough to
work great in direct sunlight while using tiny amounts of power.

The University of Washington has been working on this concept since
the 1980's. Do they work? Absolutely.

For them to be practical in gliders, I think they would have to be
linked to a PTL (Push to Look) button on the stick which rotates the
projector into viewing position when pushed and rotates it out of the
way when the button is released.

These devices could eliminate the "screen real estate" and sunlight
viewing problems which has plagued glide computers.

One might imagine FLARM traffic data overlaid on the outside world.
