Hello all,

Ø They should be okay as far as vergence-accommodation conflict but not in
terms of actual scene depth. And, if actual scene depth doesn't matter, then
why not go with microstereopsis, as in the Sony CEATEC single-lens camera (see
"Just Enough Reality: Comfortable 3D Viewing via Microstereopsis," by Mel
Siegel & Shojiro Nagata, IEEE Transactions on Circuits and Systems for Video
Tech, 1999)?
It's only fair that a smaller screen should show less depth. In the first place
it would be
unnatural to be otherwise (a small world should have small depth), and in the
second place
it will only create major problems. The window would become too small, for one
thing,
so you would have window violations all over the place. And the
accomodation-vergence
conflict would be killing. My estimate is that you need at least that 32"
screen at 8 feet
distance for 3D TV to work comfortably well.

Ø Easy for you to say.
You can't have your cake and eat it too. The capabilities of 3D depend on the
screen
size and the viewing distance. Until we get holography (or use near-eye
displays like
a Viewmaster) there is no way around that. It is not because I say so.

Yeah, all the way until the Blu-ray of Avatar will be released, probably late
this year.

Was it that evil left middle finger, the digitus impudicus, again ?

I've been trained....
Though I am an optimist with experience, which is the definition of a pessimist.
