Watch 3D glasses without glasses thanks to MIT's new technology

The Massachusetts Institute of Technology - MIT of America has succeeded in creating new projection technology whereby moviegoers will not need to use glasses when watching 3D movies.

Watching 3D movies at the cinema is not a favorite choice for many people for a number of reasons, in which glasses that support watching movies are ranked as one of the most annoying things.

This becomes even worse for people who are nearsighted or who have vision problems and must wear glasses. Besides, cheap plastic glasses are often marked and scratched. That's why MIT's glasses-free 3D projection technology is just a prototype but is getting a lot of attention from tech circles and 3D movie enthusiasts.

Glasses that support watching movies are ranked as one of the most annoying things.

Many people may have experienced Nintendo 3DS gaming machines with the ability to perform stereoscopic images without glasses. However, this latest generation of portable game consoles has been improved, but only designed for use by a single person.

Obviously this is not a technology suitable for cinemas with hundreds of seats and each of them has a different perspective.

MIT's CSAIL computer and artificial science lab has been working to create a screen that allows users to see 3D effects in a cinema from any seat without glasses. .

CSAIL succeeded in creating a prototype named "Cinema 3D".

In collaboration with Israel's Weiszmann Institute of Science, CSAIL has succeeded in creating a prototype called "Cinema 3D" that uses complex arrangements between mirrors and lenses to create parallax barriers (showing Different pixels on each side of the viewer to simulate depth). This technology can also locate every viewing angle in the cinema based on the seat position.

This technology can also locate every viewing angle in the cinema based on the seat position.

Researchers have discovered that this method can be applied in cinemas, because unlike watching movies at home, they can know exactly where the audience will sit and their perspective: seats always in a fixed position and people don't tend to move, change seats or viewing angles while watching movies.

In terms of image resolution, this technology "covers" all viewing angles from the projector , which divides the total number of pixels displayed for everyone. Another highlight that CSAIL and the Weiszmann Institute of Science have accessed is that "Cinema 3D" has the ability to preserve resolution and bring sharp images to viewers.

This technology "covers" all viewing angles from the projector.

Up to now, this prototype has not been fully ready to be marketed because it requires 50 sets of mirrors and lenses to operate. But it has proven the reality of the design and the researchers hope that they can develop their prototype into a commercial product and that may be what will completely change the way 3D movies are viewed. tradition in the near future.
