Normally when you have to watch a 3D movie you need to wear those weird-looking glasses. The Computer Science and Artificial Intelligence Lab at MIT has created a movie screen that will allow you to watch 3D movies without glasses. The technology, called Cinema 3D, not only allows you to watch 3D movies without glasses, the picture might be crisper and you may be able to watch the movie from any seat in the theater.
According to Professor Wojciech Matusik of MIT, “Existing approaches to glasses-free 3D require screens whose resolution requirements are so enormous that they are completely impractical. This is the first technical approach that allows for glasses-free 3D on a large scale.”
So how long is it before you can watch 3D movies in your neighbourhood theatre without glasses? Unfortunately, the technology is still at a nascent stage. The device is very small – not more than an iPad – and it still needs to be replicated on a larger screen, according to this MIT News update.
How does the new technology enable you to watch 3D movies without glasses?
As explained in the quotation from the MIT professor, the technology has already been there. But it is so anonymous that it would be impractical to use it commercially. Currently, the 3D display technology attempts to cover a wide angle of view – this technique gives poor resolution, especially to people who are sitting at various locations or not exactly at a location which gives optimal viewing experience.
The new technique at MIT that may allow you to watch 3D movies without glasses delivers a narrow view of angular images to each individual seat in the theater using an array of mirrors and lenses which makes the 3D effect appear from different angles.
Here is the video that explains the concept of enabling people to watch 3D movies without glasses:
But don’t some TVs already allow watching 3D movies without glasses? The 3D technology used in home TVs involves using a series of slits in front of the screen that allow each eye to see a different set of pixels. The technology is good, but it cannot be easily scalable to a large screen size so that you can watch 3D movies in a theater, without glasses. It is quite easy to make people sit at a particular distance in front of a home TV in order to be able to watch 3D movies without glasses, but in a theater the seating arrangement is such that people have to sit at various locations.
Professor Matusik further says, “It remains to be seen whether the approach is financially feasible enough to scale up to a full-blown theater. But we are optimistic that this is an important next step in developing glasses-free 3D for large spaces like movie theaters and auditoriums.”
