The latest on 3D viewing - still causes eye strain and fatique

#1NoPointMadePosted 7/25/2011 11:23:38 AM(edited)
"3D displays cause extra eye fatigue, according to a study published by the Journal of Vision today that was funded in part by Samsung's R&D arm.

A group of researchers from the University of Califonia-Berkeley found that when test subjects watched 3D displays, they reported more eye strain and fatigue and less vision clarity afterward than when they watched 2D video.

The disparity between the depth of the screen and the depth of the 3D image caused the most problems, though researchers also found the relationship between image depth and nearness of the screen also played a role in eye strain.

Twenty-four participants in the study were shown 3D and 2D video at various viewing distances, and then responded to questionnaires on their eye fatigue, neck and back pain, and vision clarity. "

Sidenote: I wish the article is written in plain English, for example, I still don't know how distance and other factors can cause eye strain. Also they could have covered Parallax Barrier technology 3D viewing, like 3DS' have.

Wait...their study was based off of 24 subjects? That's ridiculous. I'd expect better from that institution, and frankly I'm surprised that was even acceptable to be published in ANY journal.

Yeah, what kind of study uses that kind of small sample size? That seems more like a highschool project...

funny, I've never experienced any eyestrain or fatigue.. guess I'm one of the elite few that 3D was meant for.
