eDimensional Wired 3D Glasses Review

Julio writes "Today at TechSpot we have reviewed eDimensional's Wired 3D Glasses, based on the original 3D Stereo technology that became popular a few years ago, these revamped version of the glasses seem to offer much more value and compatibility to the table. Adding amazing effects to games we tested which include Jedi Outcast and some other racing and flight simulators, this item could easily make it into your holiday shop list... "The images looked very cool, and I spent about 10 minutes gawking at my new surroundings. After playing around with Jedi Outcast, I was ready for more. I checked the supported game list, and just about every game I had was listed there.""

3D is less important than field of view

[localman]

I wish more research were put into expanding the field of view. There's plenty of data to indicate that stereoscopic vision is less important for bringing you "into the scene" than a wide field of view. Here's a choice quote from The Visionary Position:

"By experimenting with the display -- moving, by degrees, from a 20-degree field of view to a 30-degree field of view and so on up to 120 degrees, the team discovered that at the "60- to 80-degree point, it was like a switch went off in your head. Instead of looking at a picture, all of a sudden you thought you were in a place. You had a different way of interacting with the display. You brought in a different set of innate capabilities."

And that was in 1982. But to this day VR seems to mean 3D on a small square screen. I mean, c'mon, we've had 3D TV & movies for almost a century. It's just not that cool. I'd take Omnimax (not to be confused with Imax) any day :)

Ah well, I can always dream and complain ;)

Headaches.

Stereo vision is only noticeable to about 30 feet out. This isnt very impressive when using a pair of 3d glasses looking at objects that are typically farther out, so I would assume that makers of 3d glasses would exaggerate the effect.

What this means is that disparity of two correlated points in the two images is greater than it should be. Your brain determines the distance more based on other cues than stereo disparity. So when it gets confliciting signals about the distance of an object your eyes have a hard time adjusting their inward tilt(to increase the overlapping visual area), this is sometimes called "eyeball lock in".

The conflicting messages of inward tilt(Brain: "Somthing is close to you Eyes!"), outward tilt (Brain: "Something is farther away Eyes!") make the eye muscles try and do the same thing at once and cause strain. Its the same strain of when you put your finger really close to the bridge of your nose and try to concentrate on it. I think this is what causes the headaches.
