MIT Developed A Movie Screen That Brings Glasses-Free 3D To All Seats (techcrunch.com)

An anonymous reader writes from a report via TechCrunch: MIT has developed a glasses-less 3D display for movie theaters. The Nintendo 3DS is one of a handful of devices to feature glasses-less 3D, but it is designed for a single users where the user is looking at the display head-on at a relatively specific angle. It's not something made for a movie theater with hundreds of seats, each of which would have a different viewing angle. What's neat about MIT's 3D display is that it doesn't require glasses and it lets anyone see the 3D effect in a movie theater, no matter where they are sitting. The MIT Computers Science and Artificial Intelligence Lab (CSAIL) created the prototype display called 'Cinema 3D' that uses a complex arrangement of lenses and mirrors to create a set number of parallax barriers that can address every viewing angle in the theater based on seat locations. It works in a movie theater because the seats are in fixed locations, and people don't tend to move around, change seats or alter their viewing angle too much. What's also neat about the Cinema 3D is that is preserves resolution, whereas other glasses-less 3D displays carry cots in terms of image resolution. The prototype is about the size of a letter-sized notepad, and it needs 50 sets of mirrors and lenses. It should be ready for market once researchers scale it up to a commercially viable product.

Interesting sleep arrangement

So that begs the question: what kind of bedding can we expect from this glasses-less 3D display?

Irregardless, I could care less.

Just give it up. That cat will never go back in that particular bag. English changes over time with usage.

Personally, I'm fine with it. Intuitively, "begs the question" means the same as "demands the question"... because "begs" and "demands" mean the same damn thing. Phrases making sense intuitively is a good thing, IMHO.

Just use "assumes the conclusion" for the fallacy (which again, makes more intuitive sense anyway), and stop trying to perpetuate the original meaning which will never, ever take over as the common usage again.

Just my two cents.

should be ready when it's ready

Well no shit.

2 Things...

[OfficeLackey]

As has already been said, I've yet to watch a movie with 3D and thought, 2D just wouldn't have cut it. This whole 3D thing is kind of a dead horse and I'm getting really tired of people kicking it. Secondly, you have to know that they will also build this into the next "gotta-have-it" television/monitor. Where does it end? It's high-def 1080p. No it's curved! Better yet, it's back lit. No, 4k! Oh 4K in 3D!! You know, any more I just want to watch a show/movie that the story doesn't suck. I want the story to draw me in so I am mentally engaged with it. NOT, "I'm watching the equivalent of paint drying". They might have used a really fancy paint sprayer, but it's still paint drying.... (Damn! I must be getting old)

Its not wearing glasses that causes headaches

It's the forced stereoscopy.... when you project different images into each eye, unless you are sitting only at certain spots in the movie theater, the angle that your eyes will have to converge to fuse the two images into a single 3d image in your visual cortex is unnatural with respect the distance that the visual differences between the two objects conveys to your brain about the apparently distance of what you are seeing.

Holograms would not have this effect, since where you are focusing on when you view a hologram is consistent with where the 3d image actually is supposed to be. The image appears as fully 3 dimensional as would looking at real physical objects on the other side of a pane of clear glass, or looking at things in a mirror.

But I imagine we're still some years away from real holographic movies being a thing.

But can you look anywhere on the screen?

This is a fundamental problem I have with 3D films. The focal point is always where the director decided it should be so if you try to look at something off to the side of the screen, the 3D illusion falls apart.
