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.

*insert obligatory 3D pr0n reference here*
Isn't this already possible on 3D games? Talk about interaction!
Real-world pop-ups!!! The JOY!

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.

Next Generation??? Hell where is the First Generation.
Traditional holograms are made from two beams of monochromatic light.
Using any old He-Ne laser you may have lying around the house, provide the light source.
The beam from the laser is divided into two paths. One beam is used to illuminate the object; the other is just a reference beam; you could even shine them while watching Baywatch or something as long as you can keep them fairly steady during the bouncing juggly scenes.
Also, try to find something in the kitchen or basement that has eight segments coated with a high-quality aluminum to provide for reflectivity in steps from 10% to 80% at 45 incidence (use a ruler or tape measure for quick measurements).
Oh, one more thing -- the laser should be on for about a half-hour to allow it to stabilize. If it's not warmed up enough after that time and doesn't seem to be very bright at all, peek into where the light comes out while it's on to check for any dust specs that may be impacting the light's exit from the device.
Bottom line -- (cos^2)(theta) dependencies rock!

"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.

I send you this message in order to have your advice.
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.
I'm waiting for this tech to be married with a video phone...as long as it's of decent quality. I'm sure that a streaming holographic projection is going to require some heavy bandwidth... Of course, what everyone will be using the new holophone for will be much akin to some posts that have been written already...holophone sex. But then again, I'm sure some of the employees of these facilities aren't going to be as happy about that...hmm. With my luck, it won't work with my GeForce 4...
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.

Never look directly at the laser with your remaining eye!
Dude, you're not funny.
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.
This should be great for med students learning anatomy. Being able to see things from all sides at scale could be a usefull learning tool for all kinds of things.
Just imagine the kinds of computer games that would benefit from this as well.
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.
If anyone has seen the movie "Vanilla Sky," they might recall the big birthday party scene where there is a hologram of John Coltrane playing the sax. If that's the kind of technology we can expect in real life, then I'm without a doubt excited by it.
I wonder how long it will take this kind of technology to really take off and start to infiltrate the average home. If it's done well enough, I imagine it could have to potential to send our old TV's to obsolete land. Imagine 3D TV. Hell, in enough time (far into the future here) we could be wasting our lives away in a holodeck type environment instead of on the couch. Remember that LCD-Paint that people were talking about a while back? These kinds of technologies in conjunction could change our lives, much the way tv and radio changed the lives of people when they were first introduced.
I suppose this is a bit of a futurist vision, but when you hear about stuff like this, how can you not get excited by the possibilities? These are very exciting times my friends... very exciting..

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.

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.

This new technology will come available with a $10 spooge guard to protect the LCD screen from any bodily fluids.
These researchers need to team up with MIT Media Lab's Erotic Computation Group.
You must have thunk "so how do you display a game in 3d with such limited screen space?"...I know I did. But here's a way around it...I think.
What you do is map your world space in a sphere (so much is 'duh'). But here's the clever thing: seeing as there must be a limit to the outer edges of your hologram, you start up a logorithmic scale from the centre of the image. So in the centre you see everything as is, but as you go out, you essentially collapse/compress space; up to a flat image on the edge of your hologram-sphere.
Does this make sense to anyone else but me? Think Carmac will do something like this? :)
-- Waht? Tehr's a preveiw buottn?
Yeah it makes sense and it's a cool ass idea. My friend is trying to figure out some cool way to make maps like this, where the center is photo-realistic from say terraserver, and then it goes to topo where the rez decreases at the edge or something. Anyhow so it looks cool but employs the effect you are talking about- projected to 2d for cool posters that say, "X place - the center of the world.", sell them to vacationers, bigger fad than those euro-letter stickers on the car.
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.
Yeah, that's called a "girlfriend". Most people don't have access to that technology yet, it seems.

This head you refer to is in the haunted house, there is also a Buzz Lightyear version. I am asuming that they are simply a 3D screen, with a specially edited video. The video is designed with the particular globe/space helmut in mind, and apears 3d when projected on the screen. A system like this could probably be used with a computer generated images now, but creating a realtime 3d image from a video source would be much harder.

Just to clarify, the parent post was actually referring to "rimjob olympics", a series of games played annually by closet homosexuals.
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.

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...

Do the users have to be trained on how to turn their heads ? what happens with people with narrow or small eyes ? I doubt it will be successful...it will be like voice-commanding: a lot of training would be needed to the point that it will be useless.
:-).
Another point is that two cameras are needed for each person. That means multiview 3d displays is out of the question.
I don't understand why they don't do the simple thing: arrange "pixels" in a cube; each cubic pixel will either be transparent or lighted up with a combination of red, green, blue color, most probably using some fluorecent substance that is lighted on electricity. The cube will be visible from most sides, except from the bottom one that the power lines will run through. I think technology is up to the point where power lines can be invisible from the eye
By the way, geeks of the future will deny entering the virtual environments of the day; they will go out in nature, because it will be the geeky thing to do, whereas everybody else will jump into their virtual costume more and more! yeap, The Matrix got it right, I think.
*em* a monitor (display), were instead of pointing around with a mouse, you have two cameras traking your eyes? With some fancy-smancy transparent stereoscopic LCD "that makes the picture come alive"?

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...
