A theory about 3D gaming tech being applied for other uses


Recommended Posts

I was thinking, a 3D HDTV works by basically showing two 60FPS video streams interwoven into each other right? (Meaning it shows a frame from one video and then the other back and fourth quickly) and the glasses are designed to basically block each eye in sequence to match up with each frame in both streams, one for the left eye and one for the right eye, right?

Would it be possible, in theory, to instead of blocking EACH eye, block BOTH eyes so both eyes see only one video stream, but have a second pair of glasses block both eyes so they see the OTHER video stream? (I realize this would require a way to give each pair of glasses it's own sync signal, or to designate one as "video one" and the other as "video two" and have the "video two" pair invert how they work from the sync signal).

In other words, with two glasses on a 3DTV, would you be able to sacrifice 3D for the advantage of two people being able to see two different things instead? You could basically have local two-player that way with each player seeing the full screen instead of it being split-screen.

(And for those HDTVs that support 240hz instead of 120, would it be possible for EACH player to also have 3D then? Provided the system can render that much data fast enough of course).

In fact, if you give each viewer a pair of headphones or put them into the glasses, would they even be able to watch two completely different channels/movies at the same time on the same tv?

Or has somebody already thought of all this and I am making a fool out of myself for repeating it?

SOunds very interesting Cyber, if you will excuse me I must be getting down to the patents office now :whistle: /run

The whole "two people seeing two different things" idea has essentially already been done. You just need two different video sources polarized in different directions, then each person wears glasses polarized in the same fashion.

Heh, everybody is suggesting that when I mentioned this, but the problem is that uses a completely different screen that doesn't require glasses and will take a few years to come out? in theory, this each is already available and will work with modern 3DTVs and glasses, the glass just have to be modified slightly so one shuts BOTH eyes and the other also shuts BOTH eyes but in reverse order the sync signal tells them to. If the glasses have any sort of firmware that can be re-flashed (I have seen ones with USB ports) then somebody could code firmware to make his current glasses do this in a few hours or less.

It would just be a software change/update for the glasses, not to mention a hell of a lot cheaper than buying multiple tvs and would save room as well.

On a 240hz tv it would even be possible to do 2D 4player though at that point there would definitely need to be a software update for the tv as well so it changes how the sync signal works to make it compatible with more than two pairs of glasses being timed at different intervals.

Not to mention the fact that since that requires motion tracking, the other person still sees your display for a second if you swap positions. A setup like this would have no such limitation.

I must say that I'd rather see such a system using polarized glasses than active shutter glasses - not a huge fan of those.

Very Interesting. I already heard of most of this stuff but really when you put it into perspective it seems like an amazing technology. It's just too bad that can't can't be more affordable and logical. They just need to perfect it a bit. Nice article by the way.
