TRICKY ENGINEERING: 3D Television



    Greetings, this is Spaceman’s Hairdo from Y2K+14, D/M10. I get the gist of what you’re trying to say here Y2K+10 me, but damn this is a mess. Reads like napkin notes transcribed verbatim. Don’t worry though, I’ll write up a clearer description some time in the near future.

3D television without glasses may be possible by combining the phenomena seen above and here or here with a simultaneously convex and concave screen…I know, it’s hard to picture…but just think of a concave screen with an eye sticking out of the middle…or even better, a satellite dish with a bubble in the middle. Just two arcs overlapping.

When this is viewed from the front the image will appear flat due to the ratio of how much light the pixels are showing, but what you will be witnessing is an illusion. The pixels on the screen will have to develop diverse relationships as this TV must turn and swivel to work (sans glasses). How would two pixels that directly correspond to a how we perceive the illusory flat image exist at opposite points on the screen develop a relationship? One would have to shine brighter than the other to make this illusion work. Just watch the video again and you will start to see how this can be done, but just more dynamically on a dynamically consistent surface. Also, with the whole thing moving about just like a satellite this seems to be a programing nightmare. Not actually, just find a central point at which the the TV’s chip perceives data. Just like with a satellite that point of reference would be the center of the bubble because that is also the point on the screen where we concentrate most.

So it’s really simple programming when you think about it. Program your data to focus on a central vanishing point of a ratio of these two images…while moving of course…it’s an overlap. Kind of simple programming…right? I don’t have the slightest idea. The TV’s motion is dictated by that focus. Dependent on the relationship of the particle pixels the TV will move and this marriage of physical movement and dancing pixels creates a surreal three dimensional experience without glasses. What this TV does is push us back, allow us to relax without becoming so lost in it. It does this by highlighting more pixels relationships in areas away from the center. This is what creates the enormity of the spatial illusion. Not the center. That’s just an anchoring point.

Picture these as large screens. Imagine our movies, which are starting to become as real as our dreams experienced this amazingly with minimal invasion of space because at any time if it becomes too much you can move out of its way and it reduces to harmless pixels, but if it’s one of those Pixar movies there’s no way you could walk away…oh, but don’t forget, the Synecdoche, New Yorks of the world have their place too.

Don’t worry, the traditional flat stuff will be around still, but the other experience is for those who want to experience the evolution of such novelties as CinemaScope and Technicolor. If we go for it good, if not, that’s not our cup of tea, that’s how evolution easily works. The loving will of the people pushes things in the right direction. We need not fear technology, because we are not afraid to Betamax something if it doesn’t move us. Sometimes technology pops up early and later returns when we’re better prepared for it…but hey, weren’t prepared back then? Well, it seems we lose something and then BANG, here it comes again in an evolved form.

Big thanks go out to the Mighty Optical Illusions blog. Found some great links that saved me from having to explain everything.
