[opendtv] Re: Part II of the psychophysics of 3-D

There are a large number of people (5,10....maybe 50%, including my wife) who 
can't "see" 3D:

My wife has unusually sharp distance vision in both eyes, no astigmatism, uses 
reading
glasses but has no discernible visual problems (no lazy eye, no crossed eyes, 
etc).
When we were younger, she could throw/catch & hit a baseball as well as
most girls and could hit
a distant target using a bow & arrow, so seems to perceive "True 3D" just fine.
And yes, over much longer periods of time, she is susceptible to sea 
sickness.....
But her response to 3D is severe and nearly immediate.....unlike nausea which 
would take awhile....

Years ago we traveled over 100 miles to our nearest IMAX theater to see 
DINOSAURS 3D.
Within SECONDS of seeing 3D (via special polarized glasses), she suffered a 
SEVERE
painful reaction and essentially cowered behind the seat before she gave up and 
left the theater.

Subsequently, we've had many opportunities to see various 3D demos at CES and 
NAB, but her
reaction has not been any better, whether using polarized glasses or new 
systems with NO glasses....

She can barely perceive 3D (comes and goes) via the old two-color system, but 
apparently
the 3D effect is so poor and blurry, it isn't immediately painful....just a 
waste of time...
and for ALL of the various systems, can't be enjoyed after removing the special 
glasses....

Personally, I perceive 3D just fine....but irrespective of the technique, it's 
very blurry, is a huge
distraction trying to get it to work correctly and wouldn't watch for more than 
the length of a short
ad or promo.  I wouldn't watch an entire program in 3D....

So what are the latest numbers re the number of people who "can't see 3D"???
Esp. as newer systems hopefully pay attention to the "Ten Commandments of 3D":

So, let's see if I can summarize the "issues."

1. If you allow the use of 3-D glasses, then you can accommodate viewing
the screen from multiple locations. But you still have to deal with the
problems of (a) making that same content viewable on different size
screens and (b) the focusing distance eye-to-screen being different from
the distance the eye convergence is trying to convey geometrically.

2. If you don't want to require viewing glasses, then you can only
accommodate a very small number of acceptable viewing positions. (Maybe
just one per screen, or perhaps column [as opposed to row] of seats in a
theater.) And you also have to deal with the issues in #1 -- screen size
incompatibilities and nausea.

3. An additional issue. Sailors who are unfortunate enough to suffer
from seasickness know that even if you can become accustomed to it after
days on rough seas, you also become unaccustomed to it after the sea
calms down. Next occasion of rough weather, same cycle all over again.
Possibly, then, if you don't watch 3-D content continuously, you may
suffer the nausea every time. And different people to different degrees.

Strangely enough, perhaps 3-D in cell phones is, after all, one of the
few media that will work well? Only one viewer per screen, small images
and/or short viewing times that may reduce the nausea-inducing effects,
and pretty much the same screen sizes for all venues, guaranteed.

I wonder why the hype concerning 3-D TV.
