First Shareable Interactive Display
Jeremy Newton writes "I want to share with you a new device that allows multiple moving images to be displayed to several users from the same screen at the same time. The project is called a "Shift in Time," my thesis project for NYU's Interactive Telecommunications Program. The driving goal of this project was to end fighting over the remote control, the gamepad, or the keyboard. It also makes room for new applications in marketing, games, and education. Recently it's gotten some buzz on Engadget.com."
This is great; Now, if only someone makes multiple streams of sound riding on the same speaker...
How about using it in the bank industry? The bank equips the ATM's with this, makes sure that the user is informed that he should sit strictly in front. Then the ATM displays "bait" information on all sides except the front side.
Does it run Linux?

Or, use the Imax like glasses, and flick between images on the screen every refresh, and have the glasses blackout for every other image, so you again only see the images you want.
Oh, and to top it off, you set up your speakers really carefully so that there's interference, and a node (no sound) from one source for person A, and a node from the other source for person B!
Then again, it's probably easier just to use two screens and two headphones :)

Wow, this kid is a one-man PR machine -- gets his page on Slashdot and Engadget, complete with his own videos promoting his work.
I'm not trying to be mean, I'm just amused and rather impressed, actually. =)
This would definitely help me screw over my cheating bastard friends at our semi-annual LAN party. I'm not sure I could set my box to run two versions of any recents games. However, that copy of Wolf ET should do nicely.....
This will revolutionize the porn viewing experience. Just think about it! Just set it up so that you could be watching some regular porn... Move to the left a bit and you could be watching lesbian porn... Move to the right and watch some solo porn... And any onlookers would just see some kittens in a field!
Damn, now where's that patent application...
than SHift In Time, otherwise it's just SH-I-T.
as the time goes, the tv will probably become less and less social activity...
as an electrical/computer engineer, I definitely applaud the fellow for a really excellent proof of concept.
however, I'm failing to see the practical impact of his work. really, per his example of the two designers, how often will one really need to share workspace with a partner on physically the same terminal?
i suppose I could see a bit of application in the real of software like X Windows and have the lenticular lens allow shift between multple desktops, but even that is stretching it a bit.
anyone think of anything PRACTICAL this is good for, rather than his fairly optimistic view?

Hasn't slashdot learned by now not to let through any stories that were submitted by the people involved in the story's subject? We get goofy ones where the guy is plugging his own site or stuff for some greedy, selfish, or underhanded reason.
This works using the same technology from those plastic animation pieces you used to get in cereal boxes. Am I right? Somebody let me know, because I can't bear to read the stupid article. If it weren't for the frat boy who cooled his room with institutional ice and thought he'd invented a refrigerator, I'd say this is the lamest thing I've read all day.
If this qualifies for an engineering PhD, I'm not sure I really care about getting one anymore. This kidn of thing has been done a LONG time ago to make rudimentary 3D displays out of LC panels. It's hard to believe it's considered noteworthy engineering when somebody slaps a plastic lens array on an LCD panel and doesn't even do the most interesting thing you can imagine with it. Viewer multiplexing? Fricking viewer multiplexing? Yeah, if you don't move your head much.
this is like those "3d" things with the plastic "grating"... i dunno what to call it. but the diff angles give diff pictures... make the picture look 3d or animated... this is stuff they have been doing with still pictures for like decades
.. is becoming maturer as we speak. It's developments like these which allow us to truly see how the world of IT will dictate our future. I, for one, am a valid potential customer of this device. Good going and keep the iovation coming!
just think of the applications to porn...
We all know the porn industry is going to benefit from this, in some very, very, very kinky way. Probably, pre and post op pictures.
What if I move my head, or rearrange myself on the couch? Will I see a weird hybrid image? And how will this handle sound?
... for the peep shows in the back of porn parlors, imagine the drastically decreased costs in the long run!

I've seen this technology for years. It's called the "Microsoft Product Line".
For example, here's what Microsoft sees:
"Windows XP Home Edition sets a new standard for performance and reliability. If you demand the most from your operating system, this version of Windows was designed for you"
And here's what I see:
"A shoddy piece of crap that is vulnerable to viruses and malware. Unable to extract the kind of reliability and flexibility that Debian Linux can".
See? Same thing's on the screen, but we see two totally different things.
Ruby on Rails Screencast
Given two movies A and B, display in quick succession A-B and B. So person P without glasses sees the average A, and person Q wearing special glasses sees B.
:)
Now let
A = chick flick
B = porn
P = your girlfriend
Q = you
and keep the glasses a secret.

At least you could have gotten a clever troll out of it instead of wasting it on THAT. Sheesh.
I could see a use for this around a gaming console for multiplayer games where each person would get a private, full scree pov. Individual headphones and you are all set.
...But I digress. TREMBLE PUNY HUMANS!ONE DAY MY SPECIES WILL DESTROY YOU ALL!
you are an idiot
would be to use a high refresh rate display and LCD shutter glasses. if you have a 120 Hz refresh rate then you can have three independent images viewed at 40 Hz. from any angle, mind you. they might appear a little dim, and 40 Hz is kind of annoying to stare at, but it would work.
and for two people, 60 Hz is definitely reasonable, especially for gaming. it wouldn't work on a refular television, but on good computer monitors it would be great.
and probably cheaper than the crazy monitors they have on that page. and you can do it all with drivers and currently available LCD shutter glasses.

I thought a one of the good things about television was that it could bring people together to watch their favorite shows. I guess this beats multiple TVs in seperate rooms, we will all be in the same room this way.
That is what we Mac users have been using for a while now. It is far more productive to have TWO screens collaborating than ONE screen shared. You wouldn't imagine what I can do with this thing. Take notes in class with other Mac users others on an ad-hoc Airport network, write up code, etc. I guess the screen concept is the next generation...
...but I worry some Dilbert's boss will say, "Buy one of these for 10 employees!" Which wouldn't work too well.
We were doing almost the same thing over 12 years ago a Georgia Tech using polarized glasses and an active shutter on the screen. Could not really find any useful application for it...
I know a company that provides a comprehensive
screen-sharing solution for local and remote
cooperation during business conferences.
All participants can use their own laptop and
its screen real-estate to do their own private
thing, but can drag applications, video, etc.,
to a central shared (typically large plasma)
screen. Everyone's mouse/cursor can co-exist
on the shared screen, manipulate the shared
application windows, etc. Very nice, useful,
not a toy. Born from a Stanford project.

Very useful.
Not only has it been done, it's already commercialized.

Applications include encumbrance (e.g. shutter glasses) free auto-stereo.
So in theory, we could visually be seeing different things, great. Too bad we cant hear the two movies at the same time or we'd go crazy.
Anyway, this would be great for applications like multiplayer games, where we'd basically be hearing the same sound.
...yes, headphones... will you really wear them at home?
ITP kids get an M.P.S. (masters of professional studies)
Of course,
they get very good at cloaking this,
by referring to their degree as simply "a masters".
its not anything special, not innovative,nor is it clever, but otherwise cute. even coming from a marketing background i don't see any potiential. Kinda reminds me of those really old toys that sing "its a small world after all" and shows a small movie using the same tech. But its a cute attempt. even for mac users who like 2 screens, they still have to pivot themselves in order to see the other screen. Still cute though.
Captian Eo at disneyland had this sort of technology a while back in the 3d glasses it used
Good thing all you have to do these days is say "X86" to make the Mac zealots be quiet.
now if only there were some way to bring this technology to baseball cards...
How am I an idiot? My post is true. Look at your karma, loser.

I've talked myself out of buying flat screen monitors with less than a 170 degree viewing angle.
Can you imagine a screen where if you readjust yourself just slightly you lose the picture and have to force yourself back into the position you've held for three hours? Sounds like hell.
And from the looks of it, hell's much more expensive than you're average screen.

Awesome self promo job, but man those Lenticular things are about as annoying as the 3d picture things I could never see right! ;)
You could use this to make an array of "Beams" pointing to the corresponding area you want different channels of sound to be heard. It works by using ultrasonic sound (which is much more directional) to create interference (the signal we want) in a given area. Interesting technology.
If you are about to mod me down, keep in mind that this post was most likely sarcastic.
I don't think that image is a good represenative sample. BOTH images have the same background (the Shrubs, lamp, etc). You could interpolate image 1 on top of image 2 and have few artifacts. You can even see the third building from the "past" in the same location on the "future" image.
I think a better sample would be 2 entirely different images.
Don't think that a small group of dedicated individuals can't change the world. It's the only thing that ever has.
This reminds me of a display at SIGGRAPH last year. It used 1000Hz DLP projector. The projector shined on 20 slices (parallel to the "screen", at increasing distance from the viewer), one at a time, so each slice was updated at 50Hz. Each slice was translucent, so the result was a convincing 3D image. Of course, you need a real 3D datasource, and the range of motion that it looks convincing is limited, but very cool. More info at Lightspacetech
From their FAQ:
How does the DepthCube z1024 3D Display work?
The DepthCube z1024 3D Display is a rear-projection volumetric display in which a high-speed DLP(TM) video projector sends a series of 3D image slices into a 3D projection volume. The projection volume is composed of a physically deep stack of 20 electrically-switchable liquid crystal scattering shutters. At any instant in time 19 of scattering shutters are transparent and only one is in a white scattering state. We switch a single shutter into the scattering state and project onto it the appropriate image slice corresponding to its physical depth. Since each image slice is stopped in the projection volume at the correct depth, the DepthCube produces a 3D image that is truly deep.
A patented 3D anti-aliasing hardware algorithm virtually eliminates the visual discontinuities between layers so that the 3D image appears to be completely smooth and continuous.
With the high speed projector sending out 1000 image slices per second, the whole volume is refreshed 50 times a second. This is comparable to field refresh rate of NTSC video in the US and PAL video in Europe (although the actual frame refresh rate of these is 30 Hz and 25 Hz respectively). Due to the high speed digital interface between the computer and DepthCube Z1024 3D Display, a completely new 3D image can be written to the display nearly 20 times each second.
Although not quite fast enough for Virtual Reality, this update rate is fast enough for real-time user interaction with the 3D image. We've even played video games on it.
How to display these images on this thing: A 360 degree spinning LED screen and we can have a whole crowd get a personal version of whatever they are watching. Combine that with the sound options that the children of the root post point out and we can really have a party!
In the video he talks about how the picture would go from raining to pouring, if you started waving your arms around....So uh...if there was a lot of movement...maybe the picture would change accordingly ;)
If I only had a patent...I could be rich (feel free to help yourself)
it would have been nice to link to ITP.. I went there too... The Thesis there are "final projects" typically.. while I wrote about the future of advertising, someone else could produce some video or some flash animation.
The program focuses now on Physical Media, ATMs are a good example of that.. but some art work you hang on the wall and it interacts with you as you walk past it, would be an other example..
Anyway, i'm not really sure I see any strong applications for this..

What is it with the recent self-promotional use of /.? Next week, I'm going to try to get my own research on Slashdot: It is a liquid crystal display designed to be used by a man and cat, simultaneously. I call it kittiplexing, and it shows the human user their normal Windows XP desktop while showing a bouncing ball around the screen for the benefit of the cat. It requires that the cat wear a head-mounted optical unit I call the Digital Light Directing Optic. But once you strap it to the pussy, you just keep getting Windows until the batteries run out on the DLDO.
You now, leave my aunt margie out of this! For shame!

BTW, lightningrod220, the answer is no. Slashdot will continue to link to whatever it wants to. I don't agree with accept/reject decisions all the time, either.

It must be Windows. It needs half a gig of RAM and a hardware-accelerated graphics card just to run Solitaire.

OK, I didn't RTA, but Depicto at http://depicto.com/ lets you share things among any number of people at any number of networked computers. And any of them can modify/comment on the image/text in realtime while all others watch. Pretty cool! I use it to work with my remote office all the time.
Space and Computers.
The question that's floating thru my mind is if two people are looking at different things on say, a computer monitor, who's the one that's going to be in charge of running the keyboard and mouse?
I see this type of technology as perhaps useful for game consoles, where one box has multiple controllers. Now if they could just figure out a way so that only certain sounds would only be heard by you, this would totally rock.
Though I'm a bit concerned about image distortion.

How would one share the mouse control with another viewer? It makes sense having on person watch a movie, while another can be playing a game or working on a file, but how would this work if two people need to interact with the computer?
These kinds of devices have been around for a while now. Most notably the Lumisight Table at SIGGRAPH last year. Lenticular technologies have been used to create these displays many times before; it is only now, as LCDs get crisper, that you can put them to more use; but I am willing to bet it still looks pretty bad.
Seriously man, don't knock it until you've seen its potential. I mean christ, how is this even marked as +2 informative still? He admits three things in his post:
1. He's arrogant and doesn't like the idea
2. He hasn't read the article
3. He HASN'T EVEN READ THE ENTIRE POST, LET ALONE THE LINK, because he thinks the guy is getting an engineering PhD.
And he has the gall to call this the second-lamest thing he's seen all day. Personally, I think his post is the lamest thing I've seen all day, because it's such a blind dismissal of new technology. If you've actually done your homework and read up on computer history, you'd know that doing that is the dumbest possible thing you could do in this industry. You might as well throw the crow in the oven, because you'll be eating it in a couple of hours.

So the angle decides whatever you want to watch. What if your wife (to the left) is watching homecooking shows and you're watching Baywatch, and you want to change position? I mean, serious "TV-leeching" requires some movement every now and then. How bothering wouldn't it be if someone just changed the channel while you adjusted the pillow, which would be the equivalent.

Wow...
Now we can actualy use those extra frames to render slight different angled scenes, so you can look around at you monitor searching for targets without actually using the mouse to turn around!
And I guess this will create some degree of stereoscopic effect on the image, leading to "real" 3D without the need of special glasses!
This can really improve the gaming experience! But wait, I guess it would be usefull with project Looking Glass too (http://www.sun.com/software/looking_glass/)!

I don't know where you are from but we already have those ATMs here in Portugal (showing a black screen for every side except the front) since some years ago.

Not exactly revolutionary... didn't hologaphic playing cards have the same effect years ago?
This trick is like those old school kids toys that have multiple image using the same method... however.. the problem with this.. is... there are trade off.. always trade off.. Either u choose to lower your vertical resolution to half (just like this case).. when everyone nerds is trying to push their screen to 2048x****, that's like taking one high res screen and chop it to half... or.. with that polarizer method someone mentioned, current fastest LCD on the market is about 12ms, which is about 83Hz max refresh rate if u try to refresh the whole screen with completely different image.. (alternating 2 different image..), then that's like down to 42Hz ... that IS some serious flickering ...
also.. another thing is.. the Twist nematic crystal are making the light from the back lite already polarized.. that's why if u try to wear a polarized sunglass to watch a LCD, colors sometimes look funky (depends on polarization angle)
So.. that won't work quite well either... (not until OLED gets popular.... maybe)
I mean it might be good to use it at some secure terminal where u don't want other ppl view it but u... but then.. most cheaper LCD got narrow view angle anyway... some even look funky when u look at it straight.. :D
so.. i mean... it's good idea.. but... is it practical...?
Heck, I'd even take another Jackson story in preference to this.

Please stop stalking me, bro.
some said game console.. where u don't need to stick with those split screen anymore... well.. guess what.. most game console now got network access.. most gamers doesnt' even leave home when they play multiplayer... so not much use either...
plus.. YES... it is some old tech from the cereal box...
I didn't know a master degree is that easy in NYU... this is more like a high school project or something... .. Ok.. maybe not the motion detection camera stuff... but... who need a camera to detect amount of motion when u can use a PIR sensor and an integrator circuit...
besides.. i thought this is presenting of having multiple screen... why do i want a few birdies flying on my TV and how much rain it pour on that poor guy on the bench when i trying to play a FPS on my console...
sorry if my tone sounds bad.. but i think this is just
If there was a true market for this kind of a system, we would be using them *today*.
Of course, it shouldn't surprise me that old technology through the years is seen as "gee whiz new" and such. People here old enough will remember when the jump (in ordinary consumer vehicles) to disc brakes was the "big thing"? These were first introduced in the late 1940's on Preston Tucker's Torpedo (disc brakes were long used on aircraft, where Tucker got most of his inspiration from). Or, what about fuel injected engines? I could show you an original Popular Mechanics from the late 1950's detailing a revolutionary engine design to save fuel, with improved horsepower - they didn't call it a fuel injection engine, but the design is all there. Or - more recently - Lexus (or was it Infinity?) has introduced a new model in their line of cars with headlights that angle as you steer - so that the headlights follow your turn. This would be revolutionary, would it not be for the fact that, yep - once again, the Tucker Torpedo had that in 1949 as well (along with an airbag system - another Tucker innovation)...
Once again, this does nothing but show that on the whole, people are ignorant and forgetful puds who seemingly gloss over revolutionary ideas time and time again, typically screwing the orignial inventor or innovator out of rightful earnings, only to see the same thing pop up again and be "ultra popular" 10 to 50 years down the line. It is maddenning, and frustrating to watch (I am just waiting for the new and cool tech called Virtual Reality to pop up again - if it happens, it will likely happen this year, given all the other wierd crap happenning - Pink Floyd getting back together? MJ aquitted? JWZ going to OSX? What is this world coming to?)...
