Discussion Overview

The discussion focuses on the physics and technology behind heliodisplay and fog screens, with participants seeking information and sharing insights about related technologies and effects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests sources of information on the physics of heliodisplay, indicating a lack of available resources beyond news articles and press releases.
  • Another participant suggests that the company behind heliodisplay has only recently announced a prototype, implying limited technical details are available.
  • A participant introduces the Tsunami Water Screen, describing its impressive visual effects and suggesting it as a related technology worth exploring.
  • One participant hypothesizes that heliodisplay may utilize a mirage effect for light deflection, speculating on the use of standing ultrasound waves to create a stable curtain of layered air.
  • Another participant mentions Electro-holography as a potentially more promising technology than heliodisplay, directing others to resources from MIT and QinetiQ.com.

Areas of Agreement / Disagreement

Participants express varying levels of interest and knowledge about different display technologies, but there is no consensus on the specifics of how heliodisplay operates or its comparative effectiveness.

Contextual Notes

Participants acknowledge a lack of detailed information on heliodisplay, and some claims are based on speculation rather than established facts.

Who May Find This Useful

Individuals interested in display technologies, physics enthusiasts, and those researching innovative visual effects may find this discussion relevant.

Hi

I'm going to write an essay on this, but I need sources of information - especially on the physics of how these work! I've googled, but I can't find much information. Could someone please point me to a good source(s) of information.

Thank you.

tsunami water screen

have you guys checked out the Tsunami Water Screen yet? I saw it at a show a few months ago and it absolutely blew me and the crowd away. It projects video onto water, and it has an absolutely phenominal effect. The waterscreen was huge in comparison to the pictures that i have seen of the helios display.

May the {stable} mirage be with us !

Heliodisplay, probably, uses mirage effect (like on the desert)
to obtain light reflexing or rather light deflecting screen.
I don't know how exactly they generate stable courtain of
layered air but I suppose that by means standing ultrasound waves.
(may be used to heat air, too).
 
You ppl may also be interested in Electro-holography - check out MIT's website, and QinetiQ.com. This technology uses holography, and it is interactive, and also it seems to be much more promising and useful than any other display technology.
