3DS: 3D effects for people with one working eye?

Hi and thanks for looking. I have glaucoma, and because of it I lost my left eye when I was 8. I've never really cared about '3D', I guess because I've gotten quite used to a 2D life; it's like my whole life is on a single screen :) But then, the 3DS is on its way, with 3D as the biggest new factor, and being a huge DS fan, I can't just ignore it.

I'm still having a bit of a hard time trying to understand how 3D works for the vast majority of you, people with two working eyes. Please correct me if I'm wrong, but basically, you always see two slightly different angles of the same object or scenery, therefore being able to perceive depth quite well. As far as I know, the 3DS will recreate this by sending two different images to each side, or eye, without glasses. These quick renders should get the point across...I hope:

Your left eye would see the 4, your right eye would see the 6. My question is, wouldn't people with one eye be able to see some sort of 3D effect on the 3DS? What I'm thinking is that, if I look at the screen, with my one good eye, from the right, I'll see the 6. As I move the screen to the right, I'll see both numbers (top image), and eventually I'll see the 4. This might happen by...

A) Moving my head horizontally from left to right and / or right to left
B) Moving the 3DS horizontally from left to right and / or right to left
C) Tilting the 3DS on place, from left to right and / or right to left

So I might not get the full 3D experience, seeing both sides of the die at the same time, but maybe one of those three options will let me see some sort of pseudo-3D effect.

Of course, this is assuming that both images don't have to be seen (processed?) at the same time, in which case my whole idea is most likely incorrect. Anyone have any thoughts on this?

People with one eye won't be able to see the 3D effect. Although you have the general idea correct of how the 3D functions, you can't get the effect by shifting your single eye's view back and forth. You need to see two images simutaneously with each eye, the brain is then 'tricked' when it meshes the two slightly different views together.

Let me explain a few things.

If you mean the pseudo 3D like this DSi Ware game: http://www.youtube.com/watch?v=p3lDoVwEmt

Then no, it's not like that. The 3DS works using parallax barries, tiny lines that block certain pixels from getting to each eye. There is a sweet spot which you must hold your 3DS, otherwise you get a double image, you can't just move it left and right to get the ffect. The 3DS works by having both eyes see two different images at once, our brain will then process them providing the illusion of depth.

It will be difficult to explain how stereoscpic 3D works unless you experience it yourself, but I will try to explain it as well as I can. Our eyes are able to focus on object of a certain distance. Any object focused at around the same distance/angel will be clear, everything else that is at a slightly different distance/angle will be blurred and get doubled. From this, our brain will be able to interpret distance. If we look at object A and Object B at the same distance, they will both be clearly focused by our eyes. If I were to bring object A closer to me while having my eyes focused on object B, object A will be blurred and double imaged, B will remain unchanged. That's how we tell distance.

People with one eye won't be able to see the 3D effect. Although you have the general idea correct of how the 3D functions, you can't get the effect by shifting your single eye's view back and forth. You need to see two images simutaneously with each eye, the brain is then 'tricked' when it meshes the two slightly different views together.

Don't worry man you're not really missing out on much. 3D can actually be quite an annoyance after awhile (probably why they added a feature to turn it off on the 3DS in the first place) You got the idea though of how 3D works pretty well but you won't be able to see it with only one eye. I'm sure the 3DS will have great 3D effects but after the first month or so it really wont be anything spectacular. 3D in video games and movies even causes some people headaches and vomiting.

Not to say that it's not going to be a fun experience and add to games, it just isn't going to wow anybody after the first few hours of gameplay.

The 3DS' effect isn't actual 3D anyway.

When real 3D happens even those with one eye will be able to see it. The 3DS is just stereoscopic 3D (or a similar perversion of it).

make a second eye patch with one half red and one half blue and bam instant 3d

I don't think you understand what I mean. Actually, I know you don't.

Think about a hologram in the true sense. Like in Starwars (even though its not true, but for this example it works), an image you can walk around in 360 degrees to see all dimensions. An image displayed on the X,Y,and Z axis, utilizing 3 dimensions.

Then think of the 3DS. Is the image actually popping out at you so that if there is a face on the 3DS screen and you tilt it you can see the sides, top, bottom of the face? No the image will distort and whenever tilted you will simply see a 2 dimensional display. It is an illusion like magic eye, it is stereoscopic 3D. Not true 3D. True 3D (3 dimensions) can be seen with 1 eye, depth, however, can not. Since this illusion requires depth perception it can not be seen to a single eyed person.

[QUOTE="yellonet"]No. If you only have one eye you cannot see 3D, as in it's very difficult to judge depth.
Just try it, close one eye and stretch out your hand and reach for some object, as you'll notice, you won't know exactly how far to stretch out before you reach the object.
The whole point of having two eyes is so that you can judge distance.

Some day we probably will. Until then don't make false statements like, "people with one eye see in 2D hurr durr."

it's not like we don't know it's not really 3 dimenions,but just stop and think how ridiculous it sounds to say "two 2D images with a special screen to make a 2D image that gives the impression it is on 3 dimensions" rather than just calling it 3D.BrunoBRS

Of course you can see the three dimensions with just one eye, but you don't experience the depth.

Up until now all gamers have seen the game worlds as a one-eyed person sees the world, so in games we have seen the same thing, this is about to change, with the 3DS, two-eyed gamers will now see things as how they see the real world.

Games will no longer only have a drawn depth but also a perceived depth.

Until then don't make false statements like, "people with one eye see in 2D hurr durr."

If an object/image is 3 dimensional is doesn't cease being in 3 dimensions with the absence of an eye.tequilasunriser

The '3D" image on the 3DS screen is an optical illusion. If viewed with one eye the image becomes 2 dimensional. What is so difficult about understanding this?tequilasunriser

However, seeing in 3D and being able to see 3D images are two very different things. If you only have one eye you see in 2D although you can obviously see 3D objects, it's as simple as that.

With 2 eyes, a person can judge the size and distance of an object in any of these situations.

ALL ACTUAL 3D IS STEREOSCOPIC if it is actually seen in 3D. The 3D environments shown in previous games are not actual 3D. The 3D effect is produced by using tricks of perspective to make it look like the world has depth. The 3DS is one of the first platforms to show environments in actual 3D as opposed to artificial 3D. People with one eye can perceive artificial 3D because it does not require the person to view it from 2 angles simultaneously. They cannot perceive actual 3D because it does require them to view it from 2 angles simultaneously.

I hope this helps with some of the confusion.

Oh wow; it's back! I started this thread, y'know? :)

Yeah, I tried the 3DS at Best Buy and it's almost everything I expected; I can shift either the system or my head side to side, and I see different 'views' of what's going on in the game; different perspectives, with background objects having more 'shift' than objects on the front. What I didn't anticipate seeing was a 'dark spot' while shifting between the images; the screen looks dark, and I couldn't distinguish which of the 2 views was being displayed.

So the two perspectives are there, sure, but the 3D effect can only be 'seen' when you see both perspectives at once, with two working eyes.
