New Technique Could Lead to Glasses-Free 3D in Theaters
Wired reported on research published in the journal Optics Express detailing a promising new system for glasses-free 3D viewing — long considered the holy grail of 3D technology, especially for home viewing. The system involves a polarization-preserving screen and a physical “parallax barrier polarizer” that allows four different screen views to be broken up vertically and delivered to only one eye at a time. It’s not immediately clear how well the system would work as viewers move around a room or cock their heads from side to side, but the scientists involved say they believe it will be useful for next-generation 3D theaters. Wired talked to a University of Arizona physicist who said the technology “is still in its infancy,” so you’ll probably have to break out those 3D glasses for Avatar 2 after all.
