If the 3DS works without glasses, why can't TV's?

The fact of the matter when it comes to 3D is that no one wants to pay thousands of dollars for the TV and then have to pay a few hundred more for ridiculous glasses. The 3DS appeals to everyone because it's glasses-free and will most likely be pretty cheap.

The technology clearly exists, so what I wonder is why are companies like Sony spending so much effort on 3D glasses gaming when they could just be developing 3D TV's that don't require glasses. It would take a few years, sure, but if this happened then the next gen could kick off with the launch of these TV's and all of the sudden 3D gaming would become standard and, hopefully, accepted by the general public.

Because of viewing angles.

It works with the 3DS under the assumption that it'll be about a foot directly in front of your face.

Big screens in your living room are meant for families to gather around and watch movies on at different areas throughout your living room whether it be on the floor 2 feet from the screen, or the couch 10 feet away, or looking through your window as the Ghost of Christmas Past tells you what your life could have been like had you gotten a 3D tv for your family.

because you can't view a 3DS at an angle

maybe one day they'll make PC monitors with 3DS tech, since usually it's 1 monitor per person and all that

When multiple people are watching tv, everybody can't be directly in front of the television. While playing the 3DS, you must be viewing it directly centered or the image will be distorted. If tv's used this tech then the image wouldn't be clear if you moved around.

Too many variables in where people are.

3ds is true 3d. Also because of viewing angles. Sadly in school yards kids who use to look over there friends sholder as he played his ds wont be able to anymore.

Costs maybe? When you're playing 3DS, it'll be a lot closer to your face than a TV would be. Another variable is how deep the 3D is for the 3DS.

Viewing angle is a pretty minor reason not to do this. Even in movie theatres, if you sit to far to the edge or too close to the front the 3D is distorted.

Don't they already have those type of 3dtvs out that cost like $20,000?

3D tv's exist that don't require glasses, i've seen one in person and this was back in 2006, I was in Asia.. Bangkok, Thailand at an IT mall and they had some setup on displays. Looking at it with the naked eye i was able to see objects appear to be off the screen. I'm sure angels and pricing have something to do with it, but they do exist.

The 3DS allows u to view 3D in a very strict field of view. Nintendo has stated already that making 3D viewable at all angles would drastically increase the price. The 3DS screen is 800x400. Now imagine the same thing at 1080p with all hte new features in TV's PLUS 3D vieable at all angles. That would be expensive as hell, and not even worth producing at this time.

It's not possible because you would have to sit in a fixed position in front of the TV and obviously you would be the only one who would be able to experience the 3D effect nicely.

The only reason Sony is pushing 3D gaming on their console is because they make 3D TVs aswell. Obviously they need 3D content in order to sell the 3D TV itself.

1. If it was truely 3-d, it wouldn't need to rely on sending different images to your right and left eyes. The brain uses many different things to determine depth perception, only one of which relies on having two eyes. Someone with only one eye can see 'true' 3-d just fine, but they can't properly view 3-d images achieved through a stereoscopic visual effect.

2. If it is on a flat screen, it is not true 3d. If it was true 3d, you could walk all the way around the image and see it from all sides. Basically, true 3d will not happen until tvs have been replaced by some form of holographic display.
