New Technique Could Lead to Glasses-Free 3-D in Theaters

Researchers in South Korea have created a new method that would allow moviegoers to simply sit down and start watching a 3-D movie with no extra gear necessary. The research was published today in Optics Express. “This is essentially the next step that was required for 3-D display technology without glasses,” said physicist John Koshel, who studies optical science at the University of Arizona and was not associated with the new work.
