"Scanning the image directly on the optic nerve" is what my CRT computer=20
screen does.
         That is called "seeing".

The promoters at Microvision would have you believe that a ray of light from=
=20
a LED or laser source reflected "directly on the retina" is different than=20
light from the moving phosphor dot illuminating "directly on the retina".

A scanning point source is a good idea - if the price can be gotten down fro=
m=20
Microvision's $4000   price point to what it was in 1992:   $795 from=20
Reflection   Technology.   (scanning a 1-D array).   Since they've only lose=
 $120=20
million so far, all they need is more funding to get it down from a half-pou=
nd=20
weight...

Here is the one good reason to have a scanned-laser HMD:   it lets you dump=20
unlimited light into the eye.   You can make it bright enough to be injuriou=
s. =20
 That's why the USAF is putting a lot of development money into Microvision:=
=20
for a hyperbright image -- it's worth doing.
