LCD lenses would make your shutter glasses totally silent
and eliminate moving parts. A limited spectrum photocell
on the glasses coupled with a tiny 'selective' pixel at the
corner of the screen would tell the glasses which movie to
show. The tech already exists in the form of auto-
darkening welding shields. Even the cheap ones activate in
1/20,000th of a second; my top-of-the-line Miller hood
responds at ten times that speed. |

This could work depending only on just how good
is the "persistence of vision" effect. That is, we
normally play a movie at 24 frames per second
because each image is "held" by the retinal system
such that we normally don't see the flicker in-
between the frames. |
|
| |
So, imagine playing a movie at 24 frames per
second, but only SHOWING each frame-image for
1/240 of a second instead of 1/24 of a second.
Can the eye still record and persist the image
during the other during the next 9/240 of a
second? (The brightness of the image may be a
factor here.) |
|
| |
IF so, then you have 9 time-slots (1/240 second
each) in which to play 9 other movies, as
described in the main text of this Idea. Your
shutter glasses, of course, need to open for 1/240
of a second, and stay closed for the other 9/240
out of
each 10/240 (or 1/24) of a second. |

Has it been done? I'm not saying it hasn't, I just couldn't find anything. If you have links that would be appreciated. |

Actually, since Sony's patent uses alternating shutters, the
technology is limited to two movies at once (unless you
enjoy watching your films in the round), so coming up with
a way to 'add' eight more _would_ be quite original. I call
unbaked. |
|
| |
Also, nobody seems to have come up with my LCD/spectral
ID concept. I can't think why it shouldn't work, and it would
create completely silent shutter glasses (even the very best
ones currently available make a high-pitched whine that
my wife can hear). |
|
| |
Eh, I'm gonna leave it up. |
|
| |
Possible solutions might be glasses that enhance persistant image retention, stuff like that. |
|
| |
I'll think about it and invite other HBers to brain up a solution. |
|
| |
But he has, at the very least to the Halfbakery definition of
originality, since his idea is not similar to the Sony patent
in design or application, only in premise. It just needs a
little fleshing out, which seems to be progressing nicely
despite your protestations. |
|

With the advances in LCD technology, the inner lenses
could retain a lo-res capture of the current image for the
9/240ths of each frame in which the glasses are opaque.
My automatic welding shield just 'displays' a selectable
degree of shade on its transparent screen, but there's no
reason why a suped-up version of it couldn't project an
indirectly-lit image rather than just blackness. |
|
| |
Also, once the technology is established, we could speed
up the filming framerate to compensate for the blackouts.
High-
end digital cameras can easily record at 240 fps, restoring
the individual movies to the perceived equivalent of 24
fps when viewed at 1:10 interval. |
