3D movies have been quite successful at the box office and viewers are likely to see more films using the technology in the near future given the success thus far. Manufacturers have also brought the technology into the homes of enthusiasts with 3D television sets many of which are quite effective. Current 3D technology requires user to wear special glassed when viewing these movie, but these can be cumbersome. This issue may soon be a thing of the past thanks to the MIT Media Lab’s Camera Culture which has created a 3D screen that does not require 3D goggles for the full multidimensional effect.
The group’s solution is not a holographic TV but rather a multiple-perspective, glasses-free 3D display. The prototype is getting attention from different segments of the technology community and was showcased at the Siggraph computer-graphics conference in the summer of 2012.
The magic behind the technology is ingenious, utilizing multi-layer liquid-crystal displays or LCDs. The different LCD layers can display a pixel-by-pixel light-filtering pattern. This refreshes faster than the human eye thus giving the illusion of a 3D image or movie.
MIT Media Lab Post Doctorate student, Douglas Lanman, spoke about the project and the glasses free display by saying that, “Holography works, it’s beautiful, nothing can touch its quality. The problem, of course, is that holograms don’t move. To make them move, you need to create a hologram in real time, and to do that, you need … little tiny pixels, smaller than anything we can build at large volume at low cost. So the question is, what do we have now? We have LCDs. They’re incredibly mature, and they’re cheap.”
