3D Display Uses Misted Water

Soulskill posted about 4 months ago | from the bring-an-umbrella dept.

Displays 65

An anonymous reader points out work at the University of Bristol into interactive, 3-D displays created by projecting light on misted water. "These personal screens are both see-through and reach-through. The see-through feature provides direct line of sight of the personal screen and the elements behind it on the tabletop. The reach-through feature allows the user to switch from interacting with the personal screen to reaching through it to interact with the tabletop or the space above it. The personal screen allows a range of customisations and novel interactions such as presenting 2D personal content on the screen, 3D content above the tabletop or supplementing and renewing actual objects differently for each user."

The Aussies use these as warning signs... (5, Informative)

Anonymous Coward | about 4 months ago | (#46724839)

For overheight vehicles, Australia uses projected light onto misted water for warning signs. Of course, people still ignore a 20 foot "STOP" sign and end up having a nice can-opener wreck.

In Petropolis, Rio de Janeiro, Brazil they have a giant outdoor mister that they project images onto that give the store of the when the Portuguese Royals used to summer in a Palace located in this city during the Napoleonic Wars. I saw it back in 2003.

Yeah that's why they use it in so many asthma inhalers and electronic cigarette fluids and lots of other things intended to be ingested.

You're thinking of ethylene glycol, a component of antifreeze.

Please think before you knee-jerk. "That sounds a little like something I do know so it must be exactly that thing so no more thought is required!" You can do better.

So that implies that those are non-toxic? Ethyl alcohol, nicotine, caffeine, cough syrup, and countless others are meant to be ingested too - But that doesn't imply zero toxicity. Drink a couple of fifths of vodka with a bottle of percoset and tell me in the morning whether those ingestables had any toxicity.

Don't be stupid. Too much of anything can kill you. Skip the vodka and Percocet and just drink a couple of fifths of water in a short period of time. Let me know how well that works out for you. Hyponatremia [wikipedia.org] can be caused by drinking too much water. [cbsnews.com]

I'd be surprised if they were still doing it within the last two decades. Sounds more like the sort of thing you'd have seen in the Ray Harryhausen era.

Re:How is this news? (1)

jellomizer (103300) | about 4 months ago | (#46727147)

That and the impressive movie interface isn't necessarily good for normal use.

The issue with Misted and Movie 3d displays is the normal translucency and clarity. Sure it is nice to see an object in 3d and it can give you some scale... However the real need is to see the detail.

3D Star Wars style, makes for a good movie, but are you better off talking to a shaky Yoda in blue, but in 3D, or a 2d full color high resolution Yoda.

I say the real trick for teleconferincing today is to move the camera behind the screen so when you look at the persons eyes on the screen you are looking into the camera so it seem like you do have eye contact.

No; what's doubly stupid about this is that this is already a commercial product: Fogscreen [fogscreen.com] was first shown in public in 2002, and interactivity in 2005. But plus and minus 9 or 12 years, what does it matter.

Anonymous Coward | about 4 months ago | (#46731209)

The group isn't saying they invented the fucking fog screen, any more than they invented the table-surface display. The developed a 3d sensing environment to allow two people to intuitively interact with the images on the fog screens and surface.

Re:Where have we seen this before? (1)

anubi (640541) | about 4 months ago | (#46732439)

Is this anything like I have seen for years at Disneyland? I guess it was at least ten years ago they used to run a nightly show at the "Rivers of America" area and they would spray all sorts of water into the air and project images into it. It looked similar to the technologies where they were projecting moving faces onto heads in the haunted house.

LOL ... (2)

gstoddart (321705) | about 4 months ago | (#46725247)

The reach-through feature allows the user to switch from interacting with the personal screen to reaching through it to interact with the tabletop or the space above it.

Right, and god forbid what I want to interact with involves electricity.

Brilliant, I'll just reach through this veil of mist and unplug this power cord or grab my cell phone.

Sounds like neat tech, but the whole getting sprayed in order to reach through it seems like something I could live without.

quietwalker (969769) | about 4 months ago | (#46725715)

I've seen the various design concepts before and they're all variations on the same intrinsically flawed theme; displays projected on either a liquid or gas that requires very still air, and a very irritating environmental system to manage, not to mention an image that is disrupted when a user 'interacts' with it because it's interrupting the 'canvas'.

I don't know of any scheme that could avoid these fundamental problems that will stop this from ever being a widely useful, much less consumer level technology.

I think we're just going to have to stick to visual overlays on 3D space, augmented reality style, at least until we can actually produce the sci-fi concept of projected holograms. Anything less is simply not useful enough.

I recall seeing this effect in some series from the nineties and earlier in a movie. It's an obvious but not terribly useful technique that we've know of for a couple decades at least. Did I drift onto the "idle" page by accident?

Re:Isn't this old news? (1)

Animats (122034) | about 4 months ago | (#46728341)

Right. Fogscreen [fogscreen.com] does this commercially. With better image quality, too. "Fogscreen" really is a fog screen. Here's Fogscreen in HD video [youtube.com] , so you can see the quality of Fogscreen, which is OK for PR but not that great. They do interactivity, too.

Water screens [tsunamiscreen.com] are available, too. Those things can be huge, hundreds of feet long if desired.

All these technologies suffer from poor resolution. It's hard to keep a layer of fog smooth and flat. Resolution gets worse further from the nozzles, too.

Nothing new. (1)

azav (469988) | about 4 months ago | (#46727299)

This approach was shown at the Wired NextFest a decade ago and in South San Francisco around the same time, some company made a device that projected onto a stream of mist, creating a "holographic" display.

Nothing new to see here.
