iPad 2 and iPhone 4 3D demonstration, no glasses required [video]
The EHCI Research Group has produced a demonstration video of 3D without glasses on an iPad 2 and iPhone 4 that will make your jaw drop to the floor! The possibility of glasses–free 3D hitting iOS devices has just become a reality.
Head-Coupled Perspective (HCP) on mobile devices allows to create a glasses-free monocular 3D display. It is based on a efficient head-tracker that uses the front-facing camera of the device. We use an off-axis projection in order to adapt the perspective of the 3D scene according to the head's position of the user. Such spatially-aware mobile display enables to improve the possibilities of interaction.
The videos are after the break, you have to see them to believe how good they are. When you have, let us know what you think in the comments!

Aaaamazing!
This was done on the wii years ago.http://www.youtube.com/watch?v=Jd3-eiid-Uw
The wii head tracking was achieved using a completely different technique. If required the infrared camera in the wiimote to track two infrared emitters that you would strap to your head (mounted on the sides of glasses).
This technology is probably doing facial recognition to track your head movement, and requires no additional hardware. It is a very clever technology use of the front facing camera, and ignoring battery issues it is a great idea.
I didn't say they used a different method, but you are blind if you think they didn't reuse code from that method. Don't pretend this was first achieved on the ipad/phone. (and it certainly isnt the first to use a camera for head tracking either)
Dan, you don't have to be so sensitive.
You beat me to this comment still pretty sweet though
WOW!!! anyways we can demo it on our devices?????
Try Jenga in AppStore :-)
My brain hurts
I was prepared to be let down. Now, all I can say is WOW!
Is this A Brand New Phone or is This An Update to the IPhone 4 ? TeamBON
Very cool.
This needs to be in Cydia. Like, now.
It is in Cydia. at least a form of it. something like 3d spring board. not quite the same thing though.
The one in Cydia doesn't use head tracking, but instead uses the gyroscope to create a "3D" effect. Unfortunately, it doesn't work anywhere NEAR as well as this seems to work.
This is too good to be true...
I agree with you. I do think this was more about possibilities than practicality though. Plus there are battery improvements being made all the time, so within 2 years maybe? Sure looks cool!
This trick has been used on the DSi (in a DSiWare game if I'm not mistaken) for the last year or so...
Winning!!
3D is really overrated. Sure, its cool technology - but it gets annoying after a while.
That's pretty cool, but I still don't like 3D.
u should like an old grumpy person... who cares
I'm not impressed at all. Of course it is a good technology, but: 1) it is useless
2) consumes a lot of battery life
3) works only in perfect conditions(it wont work when its dark)
That is what deepend and or 3Dboard needs to be like. Or is jailbreak the only future for something like this? Could/will apple utilize this?
I hope these guys enjoy their new position and perks with Apple.
Of course, because top notch French researchers have no greater ambition than to work at Apple.
Sometimes it's not about anything more than the almighty dollar. And as far as tech R&D goes, nobody really has more money than Apple.
Wow super cool
Just had a thought when watching this...I wonder how well it works with non-static images? More to the point, this video was produced demonstrating images that are static in nature, such as the varied-height targets, and the "cubed" home screen. I wonder how well it would work with games and videos?
looks good, but still not convinced on the 3d thing yet. but yeah this needs to be in cydia.
for select apps this would be amazing i wouldnt want the whole os to be like this though but awesome work keep it up man
This is not the first time this method at creating a 3D affect on a smartphone has been done. This is very much like VR Hologram for Windows Mobile produced by Pauloke on XDA in 2008. Here's the link: http://forum.xda-developers.com/showthread.php?t=425216.
Obviously this one for the iPhone is much more advanced, but I feel, that like VR Hologram, it is bound to lose its 'wow' affect a few hours, if not minutes, once you begin to use it. It will start to become irritating and you will want to remove it.
I also feel that 3D is best left for certain aspects and applications, such as pictures and videos, etc.
http://itunes.apple.com/us/app/idesktopvr/id346486982?mt=8
This app has been around for a while now. Does the same stuff from the Johnny Lee video.
That app just uses accelerometers to create the effect. The above videos are using head tracking to let you 'look' around the '3D' environment. Of course that has also been in the app store for a while:
http://itunes.apple.com/us/app/holotoy/id360692282?mt=8
Whether they have simply implemented a better headtracking algorithm than what Holotoy uses I don't know, but Holotoy doesn't work very well. It is laggy, inaccurate and often loses the lock in my experience. The effect also simply doesn't seem to work as well on a screen as small as a phone.
This headtracking would be good on a XBox or PS3 FPS game with a big TV.
Ugh... The pretentious piano music in the videos is driving me nuts.
Also, the writer of this article seems to be not quite clear on the distinction between:
A) A rendered 3D perspective - what this does and "3D games".s
and
B) Actual 3D perception due to each eye seeing different images (what occurs in 3D films/TV and on handhelds with 3D screens)
Both of these could be combined to some interesting effect - BUT THEY ARE NOT THE SAME THING.
Bye 3DS. I wonder how this could affect iPad 2 gaming.
Very impressive! Doesn't seem like a 3D screen you'll be able to share however. I wonder what happens when two faces enter the camera view.
Um...nobody thinks this is fake? You're watching this in a YouTube video on a 2D screen, and somehow the images pop right out of the phone...no smoke & mirrors here ;)
Now I get it, it's redrawing a 2d image from the perspective of your current viewing location to make it appear 3d, smart but still 2d, and not the same as 3ds
Erm, the 3DS is still 2D as well. It's just using a parallax barrier so that one eye sees one image and the other eye sees another. The brain does the rest. The parallax barrier is cheaper, but then again, this method appears to work in more viewing angles resulting in higher data and design requirements. The key here is obviously the latency between camera, software to screen drawing is low enough to trick the viewer that you're looking at a 3D object through "real-time" perspective change.
Not sure if there is enough computational power in the iPad 2 to simulate a 3D game while tracking head movements, changing perspective in real-time, and following game control inputs.
Neither are a holodeck. ;) Or the matrix. ;) Or whatever full simulation of all senses technology is out there.
the ipad2 def has enough power to do that... the og ipad, no way
Is it really possible to fall in love with an app?
... i think so!
This isn't quite the same as the 3DS and other 3D displays, because with those your eyes each get a slightly different image so you see it as 3D without moving the screen or your head. Still cool though.
Yes please.
Cool parallax effect but not actually 3D. This article suggests this is a new form of glasses-free 3D, which it is not. For it to be 3D, that is to say stereoscopic, each eye would require a slightly different image. However, in this case, each eye is presented the same image all the time but the trick is in the parallax illusion created by moving the device around.
I think suggesting this as a new 3D display alternative is pretty misleading considering most 3D content that is popular today does not require you to move the source around (movies and games). That's not to say that games and other media might not employ this technique to deliver unique experiences but current 3D media would not be viewable as 3D with this technique.
Breath-takingly effing amazing!! When does this technology debut?! I'm super pumped!!
You're an idiot.
Ray is an idiot.
Too bad only one person can view the screen in 3d at a time.
It's impossible for two people to view this correctly the way this 3d works...
This is really cool!!!
Its faux 3D and not auhentic steroscopic 3D, which makes this a neat party trick, but no more than that.
Love it!
When will this come out
This would be very cool on the iOS devices I would love to have it and to have the apps working on it kinda like bumptop for pc
Pretty part of content. I simply stumbled upon your blog and in accession capital to claim that I get actually enjoyed account your blog posts. Any way I'll be subscribing for your augment or even I fulfillment you get right of entry to constantly rapidly.
You really make it appear so easy along with your presentation but I to find this matter to be really something which I believe I'd never understand. It kind of feels too complicated and very large for me. I'm looking forward for your next put up, I?ll attempt to get the dangle of it!
Its like you learn my mind! You seem to know so much approximately this, like you wrote the ebook in it or something. I believe that you just can do with a few percent to force the message home a bit, however other than that, that is excellent blog. A great read. I'll certainly be back.
