Helio Display: Open-air hologram
- frisco 18y agoAlso here's a pretty good video of it: http://in.youtube.com/watch?v=XOSx7v87JCA http://in.youtube.com/watch?v=XOSx7v87JCA

- frisco 18y agonice, thanks for that, didn't realize.

- DabAsteroid 18y agoFor what?
- DabAsteroid 18y agoWhy do people call non-holographic 2D displays "holograms"?
- ggrot 18y agoOK, how does this work? What are the basic physics behind the technology? You can't project on "air" as far as I know because it is transparent so the light won't reflect. Anyone know how this sucker works?
- ggrot 18y agoNevermind. http://en.wikipedia.org/wiki/Heliodisplay http://en.wikipedia.org/wiki/Heliodisplay explains it. The projection surface is actually a very fine ist being sprayed. That makes perfect sense, the original website doesn't mention anything about water.
- endtime 18y ago>Heliodisplay images are not holographic First five words. Accuracy in titles is a virtue.
- frisco 18y agoOk, there's a technical definition for "hologram" which the Heliodisplay doesn't meet. But, it does achieve the star wars effect nonetheless, and that's what's cool about it.
- DabAsteroid 18y agothe Heliodisplay ... does achieve the star wars effect In what way? R2D2 could project a mid-air 3D image.

- jpcx01 18y agoNot quite open-air. Goes through about 120ml of tap water an hour, which it sprays onto the air, and uses a rear projector onto that. The video doesn't look too impresive. It just shoots up water and projects a 2D image onto it. Maybe has potential. But I'm not all that excited about spraying water into the air.
