Typically when you hit the cinemas for a 3D movie, the glasses pretty much come part and parcel with the experience. But what if you could do without the 3D glasses completely?
3D glasses tend to be a bit of a pain for people who are already wearing glasses, as wearing two sets on your face can get rather uncomfortable, making some of us just avoid 3D movies to escape the discomfort.
So the researchers over at MIT have managed to design a screen that would allow anyone to be able to watch 3D movies sans the glasses. Here’s how it works.
While the tech has been around for awhile already, it hasn’t yet graced the cinema screen and neither is it market ready yet. The version on TV involves “parallax barriers” on the screen that force your eyes to see different pixels to create the 3D effect.
To get it to work on the big screen however, the effect is replicated with a series of mirrors and lenses so that each viewer sees a parallax barrier that works for their particular location, taking into account the viewer’s head motions as well.
Unfortunately they’re not yet sure if its practical or financially viable for it to move to cinemas just yet, but maybe it will be something we’ll get to enjoy in the not-so-distant future.
