Holographic Projection

Mid-air projection... This isn't star wars, it's for real; that ps9 commercial might actually be in our near future.

Not only can you view the projection, you can interact with it as well... porn addicts everywhere are rejoicing. :p

Ohhhhh that is AWESOME! Just imagine how cool it could be with one of these things in your living room!

Of course, it won't be worth it to be used as a TV. You can see through it, and that's one majot distraction to enjoy a movie or a show. But it is really cool looking and definitely attracts the crowd if you set one up at the store. Big advertisement opportunity.

How the hell did they do it!?

[halomizer]

SWEET, that is all i have to say about that

[Roq]

AWESOME!!! BETTER PORN!!

AWESOME!!! BETTER PORN!!

I can't find any information on how this is done. Hrmph.

This is old technology. Link: http://en.wikipedia.org/wiki/Holography

Holography was invented in 1948.

But it might be time to apply it to computing or video games. That would be great.

[Yian]

One thing for sure is that those holographics effects in the movies won't so so fresh once this thing becomes popular. The movies need to come out with something more creative now.

And Vlad, the link you posted is 2-D hologram, you see that on your Visa card everyday. We are talking about the 3-D hologram in the air.

You're partly right. Read the entire article.

Quote from wikipedia article:

The first holograms which recorded 3D objects were made by Emmett Leith and Juris Upatnieks in Michigan, USA in 1963 and by Yuri Denisyuk in the Soviet Union.
This is exactly the same technique used to get it into the air.

Here is another example. http://static.howstuffworks.com/gif/holographic-environment.jpg

Can someone explain how something is reflected onto nothingness?

Christ, who do you think we are? Einstein? Most of these people arent even capable of wiping their own assholes, especially me. I just don't bother anymore. I've gotten used to the smell.

Some of them are smart. Some.

Explain to me how a conference two-way communication microphone projects holographic images...

Maybe they let the rays of light hit eachother?

h4x obviously.

[dante.hk]

I would like to see a person get a siezure becuase of it.

A cool idea none-the-less.

[wangstramedeous]

that pic posted by vlad looks so fucking lame and fake to me. that shit was photoshopped

[Yian]

Sorry Vlad, but Yuri Denisyuk never created anything that's projected onto the thin air. He was famous for his holographic plates. The first 3-D hologram he made was a picture of a toy train and a bird, known as "train and bird". It looks 3-D but it's on a plate.

Look, I don't even care about this useless technology. Just leave me and my misinformed posts alone.

I rember seeing something about this a while ago.

Im not sure if this is the same thing, but in one id see before they had a translucient stick that would flick from left to right at a certain speed, the image would be progetced onto the stick that when done at the right speed makes the image appear to be floating in mid air.

The only thing that suggests this technique to me is the Car in the second image, and the way the mans hand is either infront or behing the image, not in it.

I could be wrong, it wouldnt suprise me, but this was just my 5 cents

[Vlad]

The only really useful real world application of this technology is for holographic data storage. Storing something in the order of a few terabytes in a tiny cube would be very handy, especially with all this porn I have lying around on countless DVD's and filling up both of my harddisks.

[RogerWilco]

The light has to be reflecting off of something. I would guess they are using a very thin layer of some sort of smoke or mist to project onto, although if that were the case then it would be susceptible to drafts and breezes...so who knows. The website is useless for actually technology explanations. I vote mist.

[dimsum411]

The same effect could be made with visible laser beams which are refracted. My theory is that the lasers' trajectory are skewed by some sort of high powered prism and projected into the air, what puzzles me is how this machine manages to contain the image in such a compact area. Light obviously travels in a straight line, and since the projection is flat, I have an idea that the light is "pixelated" or precisely projected upward in a cluster of points (remember those fiber optic toys at the carnival?) I'm assuming the voltage of the laser can be changed to intensify the image size and clarity. Just some speculation, It's 12:54 and I can't sleep.

']Maybe they let the rays of light hit eachother?
That would just cause constructive inteferance as the 2 light waves passed eachother, they would carry on traveling as if nothing happened though.

This is quite cool, here's the patent for more information on how it actually works. US Patent Office (http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=1&f=G&l=50&co1=AND&d=ptxt&s1='IO2+Technology'.ASNM.&OS=AN/)

Sketchy explanation of the technology on the website:

Operating the device will not change a room's environment, air quality or other conditions. Air comes into the device, is modified then ejected and illuminated to produce the image. Nothing is added to the air so there isn't any harmful gas or liquid emitted from the device. If a Heliodisplay were left running for a week in a hermetically sealed room, the only change to the room`s environment would be from the electricity used to run the device. Although the Heliodisplay uses lasers, the images are not holographic.

The image is display into two-dimensional space (i.e.planar). Heliodisplay images appear 3D when viewed from more than a few feet away because there is no physical depth reference. Images can be seen up to 75?off aspect for a total viewing area of over 150?- similar to an LCD screen. Viewing requires no special glasses or background/foreground screening.

So the air is assimilated and ejected from the machine. I've read that charged air molecules tend to drag the surrounding molecules creating a thicker consistency. I'm guessing that in the same effect that ionic humidifiers create mist, this charged air is only charged enough to reflect the projected light and not create condensation.

Heliodisplay images are easily viewed in an office environment. Like any computer monitor or TV, images appear brighter the lower the ambient light. Also, just like viewing any computer monitor or TV, viewing a Heliodisplay image in direct sunlight is almost impossible.
