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

The promoters at Microvision would have you believe that a ray of light from 
a LED or laser source reflected "directly on the retina" is different than 
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 from 
Microvision's $4000   price point to what it was in 1992:   $795 from 
Reflection   Technology.   (scanning a 1-D array).   Since they've only lose $120 
million so far, all they need is more funding to get it down from a half-pound 
weight...

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