Neil Schneider from MTBS3D has managed to do an interesting video interview with a company called PolarScreens during Display Week 2012, a company that is in the development of a Full HD resolution autostereoscopic 3D display. In the interview you the president of the company Jean-Etienne Gaudreau explains a bit more about the product and the prototype they were displaying. Definitely a promising product that we may be seeing on the market as early as next year and if you are a bit skeptical, because you might not have herd the name of that company, then don’t be. Actually PolarScreens is responsible for the development of the technology behind iZ3D’s 3D displays, so they are not going to be making the displays, but they will license the technology to a company willing to produce them and sell them to the consumers. These upcoming Full HD resolution glasses-free displays will apparently use 120Hz panels and will also feature head tracking, but single user only similar to other autosterescopis solutions already available intended for single user at a time. Still this technology definitely looks promising, so a thing to keep an eye at in the upcoming months.

I wasn’t planning originally to post this video and write about it, but since so many people sent me the link and after reading about it in multiple popular websites apparently a lot of people did believe that what they are seeing is true. Yes, it looks pretty well made for an average user the video effects could pass by as cinema quality special effects simulating the real thing, but there are multiple things that only a more knowledgeable about 3D technology or electronics savvy person can notice. The truth is that this entire video is a joke, a fake etc… and a good way to do some viral marketing, probably at the end when its author reveals the truth it will all be clear to everyone, after getting enough publicity. But let me start with a few comments I’ve read about the video is some popular websites that you probably know very well and also read very often in regards to that video and then we can analyze a few things about the video itself. Most of them seem to accept this to be true and that is what is disturbing, or maybe just have a grain of doubt, so the author of the idea definitely has managed to succeed…
Enter this video, created by Jonathan Post, which shows an, um, entirely new way to do 3D without glasses. I’m not entirely sure how it actually works–or if it’s even real–but this device causes your eyelids to blink very fast therefore doing the job of 3D shutter glasses. … Is it real? Is it a hoax? We don’t know either. Jonathan Post says that he hopes to present the device at CES 2012, so I guess we’ll find out then! – PC World
Who’s got two thumbs and needs glasses to see 3D? Not this guy! Francois Vogel’s figured out a way to remove those pesky spectacles from the equation, and he’s ready to revolutionize the stereoscopic industry forever. – Engadget
French filmmaker Francois Vogel certainly thinks so. We’re not sure exactly how wide an adoption Vogel was hoping for with his own glasses-free 3D technology (or, if we’re honest, if this is even a 100% serious video), but we’d wager that Sony, Samsung et al. are safe for now. It appears to work by attaching a couple of small electrode-like devices to the side of the head, which force… actually, you know what? We’re not going to spoil it for you. You can watch the video below. – T3
Jonathon Post has demonstrated what appears to be a legitimate solution for glasses-free 3D TV. – Electronista
Apart from the bizarre effect that is created there are plenty of indicators that this is a bit of a leg pull — first, he’s a visual artist, and wouldn’t this be something an artist would do? Secondly, we never get to see the screen, and from the thumbnail above it looks like he’s looking at Windows. – CNet
François Vogel, an innovative filmmaker and visual artist, here demonstrates why you should never complain about 3D glasses again. Interesting, definitely zany to watch, but take this with a smile and a wink. About 97,000 of them. – Kotaku
So the idea behind this fake solution is that you attach a pair of electrodes that send electrical signals to the muscles responsible for controlling your eyelids, making them contract and retract at a very fast speed in order to replicate the same thing that a pair of active shutter glasses does. Now this is the closes thing that gets to reality, I mean you can do something like that with a pair of electrodes attached at the right place. But this is as far as the thing goes in touch with the reality and everything that is possible as there are too much “science fiction” involved in the actual implementation that is being presented on the video…
Take a look at a somewhat similar experiment made by Daito Manabe in the video above where he has multiple electrodes attached to his face that go in sync with music by sending electrical impulses that make his face muscles chance the impression of the face. See the difference? Electrodes with wires needed to supply the voltage and not very fast reaction of the muscles (this is probably related to the slow pulses of electricity being sent). Now imagine how you can fit in such a small device as the ones used in first video an electrode, powerful enough battery, wireless synchronization… oh and the two LEDs, sounds quite impossible, right? But that is just the start of it…
In the video we see some monitors that look like a professional LCDs from Eizo for example, but there is not yet a 3D-capable LCD monitor that can operate at 120Hz refresh rate frequency that looks like the one in the video. Then we see a Mac keyboard and something that looks like a Mac Pro system under the desk, something that makes things even less probable to be true. Then the guy uses a pair of infrared air conditioning remotes to sync up the two electrodes to the PC (WFT?) and after that just presses the space to start the playback. When we are talking about synchronization of shuttering at 120Hz this needs to be done very precisely and the PC itself should be doing the synchronization in order for the shuttering and the images displayed on the screen to be perfectly matched. Of course we don’t seen anything on the display that is supposed to be showing the 3D content and the blinking of the eyes can be easily recorded and recreated as a special effect and then overlayed on the video that was shot… did someone mention a filmmaker here? Notice how the guy rises his eyebrows a few times while his eyes are rapidly shuttering, this would be hardly possible unless the electrodes are very precisely positioned, so that they will not affect any of the near muscle groups responsible for operating other parts of the face.
It is entirely different thing if our eyelids would actually even be capable of repeatedly open and close at a very fast speed for more than a few times, as the blinking itself is done very rapidly, so that we normally don’t notice it at all… but that is a single blinking and not blinking 60 times a second. The eye muscles might not be capable of doing that and as the major function of the eyelids is to protect our eyes and keep our eyes moist. In order to do that our eyelids only close one in a few seconds (usually around once in 6 seconds), but imagine what will happen if they do it 60 times a second for lets say an hour. Our eyes will be literally leaking what can be described as a flow of tears and that will not happen because we are so into the deep story of the 3D movie we should be watching this way. Not to mention that if the glands responsible for producing the liquid that we also refer to as tears are not being able to keep up with the increased requirements out eyes might гet dried and this can in turn lead to actually damaging our eyes. So would anyone sane enough actually try to replace shutter glasses with a device that is forcing his own eyes to do exactly what the shutter glasses do, even if it is theoretically possible, with a very serious possibility of actually damaging permanently his own vision by using such a product.
And here I’m not even talking about the possibilities that sending electric currents to the muscles responsible for controlling the eyelids may as well be dangerous in entirely different way with high possibility of damaging your vision and not only the vision. And that goes especially if the electrical impulses you send are higher that they are safe… I mean this way you can literally become blind from watching 3D, and there are much more things to talk about in regards, but I’ll stop at this… ;)
