MIT Developed A Movie Screen That Brings Glasses-Free 3D To All Seats (techcrunch.com) 100

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.

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

      Can someone enlighten me as to approximately when the expression "begs the question" started to mean "raises the question", instead of the informal fallacy of assuming that an unproven premise is true as part of a conclusion?
      • It doesn't matter. That's the normal meaning nowadays. I suggest you use 'assumes the question' if that's what you mean.

        You "raise" a question AFTER the situation "begs" it. If you raise it too soon, it won't be begged. If you wait till it is begged, then its obvious. That in why begged questions are inherently obvious.

        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.

          You can beg your boss to give you a raise, but you can't demand it. (You can give an ultimatum and quit if you don't get it, but that's still not demanding a raise, in that your demand is succeeding.)

          • They both mean "asking for something".

            Yes, of course they differ in the details. Thank you for pedantically stating the massively obvious.

        • Agreed. Here is a relevant Wondermark cartoon [wondermark.com] to accompany your thoughts. I long for the day when I don't have to hear internet pedants correcting people about the meaning of "begging the question".

        You are arguing for a commonplace understanding of jargon, which is specifically and locally defined. That will never happen. We misuse terms from all kinds of professions all the time, as people.

        So I guess you could ask us to stop being people. Or we can go back to classifying you as a girl. At one time that was gender neutral. Hardly the case now.

      Even worse nowadays is that a lot of movies are available in both formats, but obviously there are shots which you can tell ONLY exist for the 3D version so that something "coming out of the screen" can impress 4 year olds which would never have made it in a regular movie because they're stupid.

      I agree with you that I prefer non-3D formats, but I'll be more specific. I don't like that in 3D movies peripheral and background images are typically out of focus. I want to view the whole scene, not just the camera's main subject(s). This may also harm movie-making in general because when directors know that 3D viewers may not clearly see a background image, then it can limit the creativity they apply to a scene.

    Sorry, but theaters are obsolete, and gimmicks like 3D are only going to slightly delay the inevitable. Why would I want to waste my time and money watching a movie at a theater when I can just watch it at home and get many benefits: no screaming kids, no people talking on their cellphones, a rewind button so I can go back if I didn't understand a line of dialog, a pause button so I can go to the bathroom, no sticky floors, the best-positioned seat instead of one way off to the side, whatever food I want instead of some crappy overpriced concessions, whatever kind of seat I want (such as a recliner), and the ability to watch the movie at whatever time I want?

    • Some people go to the theater to get away from the screaming kids, family members talking on their cell phones, etc which they have to deal with at home.

      • Yeah, what the other guy said: they went to the wrong place!!!

        Actually, to be fair, I will note that there are some theaters where you can have a fairly nice experience (though still no pause or rewind capabilities). Usually these are called "dinner theaters"; you get a huge comfy chair, and can order a full meal (and alcohol if you want) and eat while you watch the movie. I also hear good things about Alamo Drafthouse. Most theaters aren't like this though, and they aren't available everywhere.

      I almost never get a chance to go to the theaters any more, but I still see the value in many cases. First, you're not at home. Sometimes it's nice to go out for the sake of going out. Second, most genres of film are better with an audience. Comedies are much better with an audience, though the audience can also spoil it if they aren't invested (much like stand-up). Third, the picture and sound are almost certainly better than what you have at home. I saw Interstellar at the Chinese Theater in Hollywood and I'm glad I did. Home theaters are great, but they aren't the same.

      I could get to work on a horse and cart too, that doesn't mean that everything new is automatically a dead horse when a few people can't see the point or remained unimpressed. We had the same arguments with colour, DVD, HD, etc. I'm unimpressed with 3D TVs but only due to the ghosting issues I have with mine. In the cinema I happily pick a 3D movie over a 2D one after a quick search to see if it was shot in 3D or if it was a crappy 3D perversion of 2D content.

  • People either hate(3d) or are indifferent to it... and it's not because of the glasses.
  • 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.

Mostly when you see a movie with these folks you just see the 2D one, but in some cases they will just go ahead and rig up special glasses (two left or two right lenses).

      It's been my experience, that the movie is fuzzier with 3D glasses. Both my wife and I had experience where we'd see a movie with her family in 3D, then go see it later on our own in 2D and were blown away the second time by how nice the film looked. Now we have kids and certainly don't have the time to see a movie multiple times in the theater, but because of our previous experience we always opt for 2D.

        That's probably because there's no such thing as perfect 90 degree polarization. Each signal will interfere with the other a little bit, and you always get a bit of bleed from one eye into the other and vice versa near areas of high contrast.

  • First all the viewers must sit quite still and not move outside a narrow band in their seats. Even after that each seat gets a slice projected to it. Though the projected image fills your field of vision, it is a narrow slice and the brightness perceived will be less. Anyway the effect will be more like the 3D image on printed magazine covers like Nat Geo. With color bleeding fringing and 3D in some small central area and quite blurry in the periphery.
