Snagged once again from bearblue:

Holo-touch Technology

My big question is not "how is the touch registered," but "how is the hologram projected?" If it was as easy as the movies make it look, we'd have had it in the '70s!

If it works..

...that's pretty cool!

Well, G boy, it works like how many other electronic devices work: Little Elves.

Now go play...

According to Terry Pratchett, it's demons. Perhaps that's the competing OS? ;)

In that case, it is either fruit or penguins...

don't forget the red checkered beachball

Oh, you just sooo had to bring up that ugly subject...
::chuckles::

i'll bring up a few now and then

;p

Well then, as long as it works!

*reads* Sounds simple enough --- maybe it was too costly or too many politics were played to have it become mainstream?

Lizard Rat out.
Not a Hologram in Rensselaer

Noooo! This is bad! I know what'll happen. I'll be walking along through the mall all not worrying about stuff, and BAMMO! An X-10 Pop-up Ad right in my face! I'll turn to walk around it and BAMMO! More pop-up ads! Noooo! This is bad!

Or even worst... when your driving. Yesh. And I thought cell phones were bad... And then I'll have to figure out how to install a holo pop-up blocker on my car! *twitch*

Marketers are evil... They made advertisements, and I could just SEE this being a problem. All you need is some tech person to tell a marketer how to do something, and 10 seconds later, you'll be up to your eyeballs in adverts.

Sorry, I don't wanna go to the mechanics to have them align my tires and install the newest patches in my car's holo display.

"how is the hologram projected?"

The theory goes, that the image is projected with small low power lasers and mirrors acting as beam deflectors. Sort of what you see with sky based laser light shows. The (two or more) intersecting lasers beams cause a light based interference pattern that you can actually see.

In many ways, it works through light refraction and reflection, much like this little gimmick:

The difference is with this type of hologram compared to the light show variety, that you don't need smoke, reflective gas (or glass) or even a moisture level to reflect the light to your eye - the air is "excited" at just the right frequencies and it will work just fine - but tends to be very difficult to work with as the properties of the air and the wavelengths tend to change rapidly with the environmental changes. So not only do you have to have a lot of computing power to adjust the image, but you need very fast optical and reflection systems to make the image appear at all.
