International. Researchers from Seoul National University are working on a new development to view glasses-free 3D images in cinema, using a system that will allow the public to see different images in each of their eyes.
Thus, the brain is the one that generates the illusion of depth that the 3D effect provides, without the need to use the glasses. Experts explained that the new system would create a barrier that would be located on the screen.
The so-called barrier would be bars that would darken certain parts of the screen, in a kind of vertical columns that would redirect the light so that one part reaches the right eye and the other reaches the left eye, but preventing the images from overlapping.
The screen system is similar to how 3D glasses work, which polarize the image so that one eye sees an image and the other eye the rest.
The projection of the film also influences this system. For the 3D that is currently in movie theaters, two projectors are used that emit images with different angles, but in the new system it would use a single projector that would be located behind the audience, as it works today.
Although the research continues, the researchers are betting that in the future this will be a simple, compact and cheap solution for 3D cinema.
