The Oculus Rift--are there gender-linked variations in our perception of 3D virtual reality?
So--have you noticed that more women seem to have trouble with 3D movies than men do? "Trouble" being anything from migraine headaches through motion sickness and vomiting? There may be a hormonal reason--men are more locked into parallax motion, women onto shape-from-shading. Guess what the computers emphasize in everything from IMAX movies through virtual reality trainers?
"It’s super easy—if you determine the focal point and do your linear matrix transformations accurately, which for a computer is a piece of cake—to render motion parallax properly. Shape-from-shading is a different beast. Although techniques for shading 3D models have greatly improved over the last two decades—a computer can now render an object as if it were lit by a complex collection of light sources of all shapes and colors—what they they can’t do is simulate how that tiny, constant flickering of your eyes affects the shading you perceive. As a result, 3D graphics does a terrible job of truly emulating shape-from-shading."
Another thing only someone taking personality and skills tests would currently notice--
"They found that people taking androgens (a steroid hormone similar to testosterone) improved at tasks that required them to rotate Tetris-like shapes in their mind to determine if one shape was simply a rotation of another shape. Meanwhile, male-to-female transsexuals saw a decline in performance during their hormone replacement therapy."
This suggests I should never waste time trying to determine positional sequence of shapes if I don't see it immediately. Because it may be a 3D simulator. It doubt seriously that it was designed to penalize women in the tests--but it can stop them cold if they get interested in the problem, wasting precious moments in timed tests.
