3D without glasses

While Apple is only preparing us for the fact that soon there will be 3D TVs that can be watched without special glasses, Francois Vogel has already proposed a method without glasses.



3D cinema burst into our lives quite recently, but it has already managed to get a huge spread. Almost every 5th film comes out in this format. In order not to strain, sitting in glasses, the inventor suggested another way. Under the cut video, which is a bit shocking.

There are several ways in which a three-dimensional image is formed in the viewer's brain, there are several, and each of them is not perfect. One of them is when a picture appears on the screen for the left eye, then for the right, again for the left, and so on. The shift frequency is about 100 frames per second (50 images per second for each eye), that is, our vision does not notice flicker. But this technology requires expensive active glasses with curtains, consistently covering the right and left eyes in accordance with the change of frame. Such glasses should be synchronized with the TV. Francois Vogel suggested using “natural” curtains - eyelids. How it looks - look!

It is not known if this video is true, or just a funny joke.

But assuming that this is a real prototype, would you like to replace 3D glasses with this method?
