By From: Wired.Com
TV manufacturers want to bring that experience to your living room with 3-D displays that work much like the ones in the theaters. Major consumer-electronics companies, including Panasonic, Mitsubishi and Sony, are betting on 3-D, with compatible TV sets planned for the market in 2010.
3-D TV Menu Systems Are Surprisingly Complicated

To understand why, here’s a short primer on how our vision works. Our eyes are about 3 inches apart, which means each eye sees a slightly different perspective of the same scene. The brain takes images from both eyes, fuses them together and uses the difference between the images to calculate distance, creating a sense of depth.
Getting the 3-D effect at home involves tricking the brain into doing something similar with the images that it gets from a TV set. But that’s not a trivial problem: TV makers have to figure out a way to precisely show a set of slightly different images to each of your eyes.
So how do they do that? Here are the key technologies that are making their way into 3-D TVs.
