XpanD, a European manufacturer that makes active-shutter glasses for movie theaters, as well as 3-D glasses for Panasonic and Vizio TV sets, is developing universal glasses that will work across manufacturer lines.
One of the negatives of 3-D TV is that viewers must always wear special glasses to view the three-dimensional effect. But one “gotcha” that most viewers don’t know yet is that virtually all of the glasses being packaged with early 3-D TV sets are proprietary to the manufacturer’s brand.
That means 3-D glasses sold by Samsung won’t work with Panasonic, Sony or other set brands. Forget bringing your 3-D glasses to a viewing party for a sporting event at the home of a friend using a different kind of 3-D display.
The cheap, polarized spectacles required to view 3-D in movie theaters won’t work at home, either. Most of the new 3-D receivers require “active-shutter” glasses that have to electronically synchronize with the TV set.

ESPN will produce both 2-D and 3-D broadcasts of the 2010 World Cup events with a single mobile production vehicle on-site in South Africa.
ESPN has been making some big promises about bringing to home viewers a minimum of 85 sporting events in 3-D over the next year. Those programs will launch on the fledgling ESPN 3D network on June 11 with a World Cup soccer match between South Africa and Mexico. The network said it eventually will air 25 World Cup matches, Summer X Games, college basketball and football and the BCS National Championship game.
In the meantime, ESPN’s production staff is learning how to produce -3D programming in the most efficient and cost-effective way. It’s a lesson that many will be watching and ultimately benefiting from. Read the rest of this entry »

When viewing movies, most less than two hours in length, binocular dysphoria has not been a huge issue for audiences.
Most 3-D display technology, whether in the theater or at home, requires viewers to wear electronic glasses that are timed to open and close rapidly. A slightly different image is projected to each eye, and from that difference, the brain creates the illusion of depth.
However, our brains process visual information in many different ways, and human depth perception is a very complicated business. The brain uses 10 different cues to figure out the distance of an object. One if them is parallax, which is used by most 3-D TVs. For 3-D to work, the brain must reject several of the other cues in favor of parallax. Read the rest of this entry »
