Do this with various photos taken with the 3DS (of varying distances from the two cameras) and you'll understand how the effect works. It's the same effect you get if you alternate between looking at anything from just one eye and then the other back and forth. As soon as you're looking through both eyes again, depth perception returns. Unless you're only capable of seeing either the left or right eye image for a given frame, or one eye is significantly stronger than the other, the effect will be the perception of depth. So if the 3D effect doesn't work, or is weak, it's not the display; it's the viewer. Technically speaking, the human eye only sees flat images projected onto the back of the retina. It's only when the brain combines both left and right eye images simultaneously that a person is able to perceive depth. If you're getting this effect when staring at a flat, non stereoscopic image, you're not perceiving 3D; you're seeing double. |
I guess in this case your brain is assuming you are still watching a 3D screen so it creates the illusion that everything in the foreground pops out. (Because it assumes the letters are supposed to pop out) It's the same reason people get a headache from watching a 3D screen: We are used to using 2D screens so our brains try to focus on everything at once even though our eyes can't focus both the foreground and the background on a 3D screen - just like in real life.
On a side note I always get a headache from watching normal LCD screens but I can play 3DS for hours without feeling dizzy. It's so much easier to watch things when they are not aligned on a single 2D plane because your eyes can focus on things further away. As long as you don't try to focus on multiple things at once on a 3D screen (you can't - you can't focus on your hand while focusing on something 4 feet away, either) you should be fine.
I've always been the guy who complained about feeling dizzy after some hours of TV. But now, in the age of 3D, all of you will complain about feeling dizzy and I'll just watch. And watch. And watch. Behold 3D!
