Next Generation of Holographic Images
suman28 writes "Imagine being able to view an image from all sides and have it interact with you. Scenes or images pop-out at you and change on the fly and are viewable in full color. Best of all, you don't need head-gear or any wearable device to make this possible. They are generated by a computer with two cameras that track your eye movement and there is a transparent LCD screen between you and the display that makes the pictures come alive. Though it may be a while before this becomes part of our daily lives, it is interesting to see what the kind of research being done on this. "

Real-world pop-ups!!! The JOY!

"Research". So that is what pr0n is called now....

Cool technology though.. I guess we are getting to that future we were wondering about 10 years ago..

more often than not 3D is distracting rather than engaging. the best way to make use of 3D is in applications where we EXPECT a 3D image.
when we drive down the street, since everything is behind glass anyway, it sort of reduces the 3d-ness, doesn't it?
It may not be the flying car, but I'm amazed by the technologies that I was convinced not long ago, were decades out on the horizon. Holograms, Cybernetic prosthesis, cheap lasers, and common genetic alteration. Good times. Seriously though, here's to hoping the flying car is next.

I wonder how the NYU system would manage with multiple users? Can the "alternating bars" system be adjusted for more than a single user at a time?

"Alright guys, we have 3D that anyone wearing inexpensive, lightwieght glasses can see. I think if we put a special screen between the image and the viewer and add two expensive cameras that must be able to see and track the viewer's eye movements, we will have brought 3D imaging into the future!"
Poppycock.
New ways to do 3D rendering are cool, but they're never going to escape the lab unless they do something not otherwise available in a more economical package.

Still the diffraction pattern from just one high-resolution hologram can easily use up more than a terabyte of data--enough to fill 1,600 compact discs
This is the kind of technology that pushes the speed of technology forward. Not only will gigantahumongous hard drives be required to hold this data, but extremely large memories, fast processors, and fast video systems will be needed. For a few years now computers have been quite fast enough. The web only needed a certain amount of horsepower, and as much as Microsoft has tried, there really a limit to how bloated and slow IE can be made. The newer chips eat IE for lunch. That's bad news for chipmakers, because it's hard to sell faster computers to customers who are satisfied.
This technology is not just going to help whoever develops and sells it, it's going to indirectly help everyone. Get ready for the next tech bubble in the next few years - except this time, when Greenspan says the magic words "irrational exhuberance" sell that shit.
Get your stinking paws off me you damn dirty ape
For years now we have been playing games in 2D,(ok sometimes shitty 3D) and a controller with several buttons.
All that has improved, in all these years is graphics quality, and bigger, more-in-depth games. But we continue to use the same interface to the game, therefore all games can be summed into, push this button to do x, push this button to do Y, or combinations etc.. Games have become boring to me.
But to get real innovation in games, we need interfaces such as this hologram tech, or forced feedback suits etc.
When I can manipualte a 3D object(like an apple)with my hands and fingers, and I can feel it, spin it etc. That is when games can become really interesting as escapes from reality.
I know there are people working on these things, and I know that there are quite a few difficulties but, I think only then will Gaming come into its own, ESPECIALly INTERACTIVE GAMING.

Just think what holographic pr0n would do data storage business.
in the arcades where it belongs!
Since home game systems have caught up with arcade hardware at low cost, there isn't a sufficient technology advantage to keep arcade gaming advantageous and afloat.
Serious holographic displays on arcade machines would be fantastic, and home consoles wouldn't be able to touch it for many years since TV/monitor standards are so slow and entrenched.
Note: please allow 3+ years for development and adoption, and keep your fingers crossed that arcades still exist then.
Finally, something worth moving up to from my 12 inch CGA.

If you think this article is sincere, here are some more of today's headlines for you:

So do they think that people with 20/20 vision can actually view this for any length of time without casuing major eye strain, vertigous reaction, and any other focusing issue?

Sounds wonderful, but one limitation that jumps immediately to mind is that the 3d effect is limited to a single viewer. I was reminded of the scene in "Minority Report" which shows Tom Cruise watching 3d video of his deceased wife, and then the eerie image distorion of the wife as the camera shifts from Cruise's POV to circle behind the projection.
Flipping moron. Stare into a class IIIb laser for a while. While you're at it, stare at a solar eclipse and do some MIG welding without glasses.

Even though everything is "behind glass", you are still seeing 3D. Afterall, the glass is transparent, it's not like the glass is "producing" the images...
Besides, driving down the street, you will want some *depth* perception. What's funky are those prescription windshields... Try being a passenger in one those cars. You almost need to be stoned/drunk to survive that without a migrain.

quote from article: "The big problem with television isn't that it's flat," Benton says. "It's that they canceled Twin Peaks after two seasons."
Well, I think the bigest problem is how outdated his reference is. Next he will be complaining about how the CHiPs didn't get picked up for an additional season.
A lot of research goes into undertanding how proteins and other bio molecules fold and fit together.
This can be difficult to understand for a researcher that is looking at a flat screen. Also hard disk needs for doing this 3D would not that ridiculous, as the view from different angles can be calculated from scratch based on the chemical composition (rather than stored than having the computer storing the information of each possible angle).

I already play 3d games where I view an image from all sides and it fully interacts with me. Scenes or images, in living colour, pop-out at me and change on the fly. Even better, I can interact with friends in a dynamic playing environment where different, continously moving, fully realized 3d images are viewable by all participants from all possible angles.
It's called "sports". Get off the couch, fatties.
Actually it does work for more than one viewer. Have you ever seen of those hologram pictures? It works on a similar principle.
"Though it may be a while before this becomes part of our daily lives"
If ever, probably never.
Holographic projection systems will never become part of our daily lives until its actually a 3d image being projected into the air that EVERYONE can see, not just one person with two camera looking at him.
I wonder if it'll give me the same headaches? I mean, after all that 3D pr0n, I'd already expect a headache, but what about when I'm just doing research? *sig*
"Imagine being able to view an image from all sides and have it interact with you" Wow! That's exactly like what I see every single day!

Man, they've been doing this kind of stuff since the 70's. Why, I'd bet that everytime me and the gang would be investigating a mystery, some embittered ex-carnival employee, or some crooked investor would use this exact same technology to project a ghost or some other apparition to scare away people who might horn in on his fortune. Oh wait... lines... between fantasy and reality... becoming clearer....forget what I just said.
I wonder if they might look something like the holo-pictures in these shots in this scene from the Attack of the Clones DVD.

Sounds wonderful, but one limitation that jumps immediately to mind is that the 3d effect is limited to a single viewer.
Yes, but is this really that much of a limitation? Obviously for most computer work (or play) there is only one user so then it does not matter. In fact, it could even be an advantage, since the guy next to you on the airplane would not realize that you are watching pr0...er, see your sensitive business documents. For other uses, say family video night, you would have to replace one screen with several of these devices. That would not have to be very expensive, especially not compared to getting one of those enormous TVs that everybody has these days.

I thought we were supposed to have large rooms which could holographically take on the appearance of any environment by The Next Generation, complete with lifelike artificial characters? Not to mention warp drives, food replicators, and a sentient android....

Holograms do more than simply stereoscopic 3D. A hologram encodes the entire wavefront of the image, not just two positions like 3d goggles or other cheesy steroscopic devices.
This differences is substantial: the amount of information presented to the eye is vastly larger than simple stereoscopic methods. In a simple stereoscopic image, all objects and surfaces appear to be in the same focus plane. Holographic images essentially gain a 3rd axis of resolution by adding a very large number of focus points in 3 space.
This also allows for true perspective wherein different viewpoints provide different information. You can 'look behind' objects in a hologram, which you cannot do with steroscopic tricks.
Thus, true holograms provide a qualitativly better experience over existing 3d methods.
That's only the NYU system and the article says later that they're working on that. The MIT true-holograph system can produce the 3D images for multiple viewers, but is limited by the massive quantities of processing power needed. Meanwhile the NYU system runs on a pc but only gives the effect to one person, though:
"The group is also working on a system that would simultaneously provide 3-D views to multiple observers, such as a team of surgeons debating the best approach to a difficult procedure or a group of video game players competing on a shared monitor"
Holodeks always break down and take over the ship or house with weird characters out of books.

Sorry to be pedantic, but holograms are created with interference patterns using a laser on specially treated photographic materials.
What's referred to here are not, infact, holograms by definition. It's merely a 3D display technology.
(Holography is a hobby of mine...it's amazing how much fun a guy in his bathroom can have with a laser and some chemicals!).

Go suck on a bog-lolly, urinal-breath.
So this brings us one step closer to an invisibility cloak. Simply plaster these displays on the sides of a box, find a "victim" (i.e., person to whom you want to be invisible), track his movements and pipe the stereo image that would be behind you...
If we get thisworking with multiple people, I'm sure people might pay for this. Otherwise it might be a nice parlor trick...
(perhaps I should patent this idea...but here it is on slashdot as 'prior art')
Just great, bad enough I get pop ups in my browser, the possibility of popup spam on the Wintel box at work, but now I may have to put up with pop up sharks from Jaws XI like poor Marty McFly did in Back to the Future.
Seriously though, while this is fairly cool, it could also lead to some extremely annoying street advertisements on the sides of buildings. Its bad enough to have billboards everywhere, but now ones which can actively annoy you in 3D? UGH!

Ooops, communication problem.
I was talking about the first article where they create a real hologram in some material (I forget now what that was - some kind of plastic?). THAT technology is cool.
That's what I thought until I READ THE FCUKING ARTICLE. You might want to try that occasionally.
Because the new video holograms produce fully 3-D images that float in space near the viewing screen, they can be examined from different angles by multiple viewers.
Technoli
This is cool technology, and does have obvious practical uses as outlined in the article. But it will never replace the potentials offered by HMDs (Head Mounted Displays).
HMDs offer the the one thing you can't get from a 3rd person perspective - immersion. Unfortunately, HMDs still have some serious drawbacks, the greatest of which is the fixed focus. Some HMDs are supposedly focused at "infinity", but they are still fixed focus in that there is no way to create the different levels of focus that the real world offers the eyes - everything is at the same distance. Thus, your eyes do not change focus as they do in the real world, which leads to eye strain. Once this issue is overcome, and issues relating to FOV (field of view) vs. resolution (namely you can't get a big FOV with high resolution yet for any reasonable amount of money - it is always a trade off) are surmounted, the ability to work and play in simulated VEs (virtuals environments) for long periods of time will become a reality.
That is what I am waiting for...
