In my last post, I mentioned a video display product, whose web page (at least the front page), contains no mention of the actual physical mechanism used to display the image in the air.  At first this seems odd; if they really have such a wonderful technological breakthrough, you’d think they would brag about it!  (Modulo patent issues, etc; but if that was a problem I doubt they would be publicizing themselves at all, yet.)

When you finally find out why, it makes sense; the technology involves spraying an invisible screen into the air, and projecting the image onto that.  While there is no theoretical reason why it couldn’t work, it just sounds hokey; and raises interesting questions like “where does the excess spray end up?”

Anyway, this got me thinking about another favorite technology of mine; the head-mounted display.  I first heard of this particular project at the HITL lab at the University of Washington (you-dub to the locals – wait, that’s me, now!).  The technology involved beaming a video image directly into your eyes; no screen required.  Well, this seemed very cool; and when a company (Microvision) was spun off to commercialize it, I even invested for a year or two.  (Internet bubble, I made a few hundred bucks off them.)

Anyway, you may be asking yourself – what is the similarity between Microvision and the fog-TV company?

I’ll give you a hint – see if you can find any use of the word “laser” on the Microvision web site…
