Discussion Overview

The discussion centers around the feasibility of holographic projection without a physical surface, exploring the technology behind such projections and the implications for practical applications. Participants express curiosity about the mechanisms involved and the potential for commercial use.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant wonders about the possibility of projecting images without a surface and admits a lack of knowledge on the terminology.
  • Another participant references a website that discusses a technology claiming to achieve this, though it does not identify itself as holography.
  • Several participants express excitement about the technology and speculate on its workings, including the idea of ionized air as a medium for projection.
  • One participant suggests that the technology might involve a curtain of ionized air and an electron gun, but questions the feasibility of producing a range of colors with just nitrogen and oxygen.
  • Concerns are raised about the safety of firing electrons in the air and the practicality of the technology, given its prototype status.
  • There is mention of a lack of widespread popularity for the technology despite its futuristic appeal, with some attributing this to its prototype nature.
  • A participant recalls that the technology may function similarly to a stereoscope, requiring specific positioning of the user's head for effective viewing.

Areas of Agreement / Disagreement

Participants express a mix of enthusiasm and skepticism regarding the technology's feasibility and potential applications. There is no consensus on how the technology works or why it has not gained more traction in the market.

Contextual Notes

Some participants note the limitations of their understanding of the technology and the speculative nature of their claims regarding its operation and safety.

Is it possible?

I have always wondered; and have never heard anyone mention the possibility.

By hologram i mean to say a projection of an image without an apparent surface for projection. Perhaps in a container of some sort. I am so unknowledgeable in the subject i find it hard to think of correct terminology.

This is so Cool

This is so cool! Anyone has any idea of how it works? It claims that it does not add anything to the air. Would it just simply be ionised air?

I've been trying to wrap my head around this for over a year. I was thinking ionized air but would that really allow images to be projected on it? Hmmm.

There was quite a bit of hype when the company first announced this device. The hype seems to have died down a lot since then. I'm surprised they haven't licenced the technology yet. This would be great for advertising.
 
Isnt it Crumbles!? Am i not the only one amazed by this.

Take a look at some of the screenshots.

They used to have videos on the site. I'm not sure if they still do. I know they took down a lot of the videos but I still have them saved on my hard drive. If anyone wants them, PM me and I'll email it to you. You just need an email account that let's you receive attachments ~5MB in size.
 
I was thinking maybe the gadget produced a curtain of ionised air and then there's some kind of electron gun that beams electrons of various energies at it and that somehow interacts with the ions to emit light of various colours depending on the frequency of the electrons from the gun.

But I don't think it can be that simple because air is mainly Nitrogen and Oxygen and it would be hard to produce many colours from just those two elements. Also, having electrons fired all around would not be safe.

The site claims they use LASERs but I can't see how! But boy do I wish I had got on to such an invention at 20 yrs of age!
 
I don't understand why this isn't extremely popular. Something so futuristic should be the a large interest for companies.

There is a lot of interest, the company was plugged by cnn last year. The system is still very much a prototype.

IIRC it worked like a stereoscope. There are slots in the screen so that each eye effectively sees a different picture.
Big drawback is that the user has to hold their head in a specific location.
