3d is a technological zombie idea. Binocular vision gives an ability
to perceive depth in the visual field, but a much more powerful source
of perception of depth comes from the relative motion of objects in
the visual field when one moves ones head (and eyes). The range of
motion of the head and eyes is much greater than the relatively small
displacement between the two eyes of a typical human. Thus there are
*two* visual cues that allow humans to perceive depth. If the two give
conflicting information there is a fundamental cognitive dissonance,
which happens deep in the visual cortex and is very difficult to
ignore. It is this dissonance which causes the discomfort. You can
mitigate it somewhat by sitting perfectly still and never moving your
head for the whole movie persentation. But sitting perfectly still for
long intervals is also a cause of discomfort to the human animal.
The nineteenth century stereopticon did not display this problem
because the viewing lenses were small and one saw nothing the moment
one moved ones eyes away from dead center on the lenses.
Moving eyes providing perception of depth is easily verified while
driving at high speed on a highway. It is not just foreshortening that
gives you certain knowledge of which is the closest vehicle of the
several vehicles ahead of you.
I think this is a valid technical explanation of why some people are
bothered by the video 3d technology. Disliking 3d is absolutely *not*
something to be embarrassed about. Being able to watch a 3d movie
without discomfort is a clear sign of a perceptual deficiency.
You can still see the movie without puking if you put on the 3d
glasses and then put a post-it on one of the lenses. It doesn't matter
which one. With one eye, you will see one picture. If the wierd
monster lunges toward the camera, you will perceive the rapid depth
change without benefit of binocular 3d.
