During the Tech Boom there were numerous companies and people working on Head-Mounted displays.  As a dealer for Xybernaut, one of the only dedicated wearable computer vendors at the time, I bought a nice unit from Olympus.  It was one of a very small lot of units, and was built to integrate into the Xybernaut units.  I used it for a lot of my WarBlading efforts … our “war driving” on roller blades.  🙂

Shimadzu is one of the vendors who has persisted in this space … they have always had an impressive (yet costly) solution.  Their Data Glass 2/A has some impressive specs, and I can’t wait to see exactly what the Data Glass 3 will be!

What got my started looking at this again was a post I read that lead me to some more current research.  I came across this web page by Ozan Cakmakci who designed a new head-worn display, and wrote some papers about them.  It’s cool to see that people are still looking at this.
