Oliver, being one of the Grandfathers of HMDs, you should remember a =

where QVGA was considered high res.  You were still making good products

alphanumeric display, but as a graphic display it...sucked.=20
Now Microvision has increased the horizontal resolution by 80% -- for =
only
ten times the price -- and it is quite good for graphic images.

QVGA was good for getting first-time people excited about the potential =
for
HMDs, back when.  And is still good for simple alphanumerics at work and
toys at home.

I made VGA HMDs and they had to be squeezed in FOV to avoid the jaggies.
SVGA let me deliver 40=B0 FOV where individual pixels could only be seen =
if
you really squinted.

As soon as I get these projects off my plate, I'll be back with the =

You have it right - consumer acceptability is going to be about the =
optics
and not the resolution of the panel - we've reached the apex of panel
resolution.   New and innovative optics will give the industrial =
designers
something to work with to design an appealing product.  The panel really =
has
not much to do with the consumer acceptance of a product.  No panel can
compensate for bad optics - yet.
=20
-Tony
 Yeah;  one has to assume that the designer will make  the optics low
aberration and distortion free.=20

I still don't know how to make them less ugly than Jordi glasses.  40=B0 =
FOV
on a 1/2" square display is an unavoidable 21 mm back focal length.
Something remains to be invented.
