Without the Special Red-Blue Glasses, how would Users be able to see into the Third Dimension?
We've all seen 3rd Dimensional Images without the glasses, bluish red blurs, so...how did Nintendo crack it? How did they manage to produce 3D Imagery that doesn't need to use those special filter glasses?
 
The 3DS will use a parallax barrier (basically a polarizing layer on the screen) which was created a few years ago. This basically works as a lenticular 3D image (those plastic pictures that change when you move them or change the angle).
The difference is that instead of having different images when you change the angle, the device will create two separate images directed to each eye.

The downside of this technology is that you have to hold it at a specific location or you'll end up seeing mixed images or double, which isn't a big issue since the 3DS is meant to be held at about 1 ft from your face. In a 3D theater or 3D TV people watch from all over the room so this concept can't be used.

By the way, the technology was developed by Sharp and bought by Nintendo. Many companies do research and create technologies and some others buy, copy or 'are inspired by' the technologies to create commercial products. Most of the big companies do that.
