3D expert details possible 3DS tech

More ways Nintendo may achieve 3D without glasses

No one cares about the purpose of life or the creation of the universe anymore. The big question of moment is how will Nintendo make a 3D handheld that doesn't require glasses?

Speculation is rampant, but Cambridge University 3D display expert Neil Dodgson has described to CVG multiple ways Nintendo could achieve the specs-free effect. The important thing to know is that 3D is achieved by showing each eye a slightly different picture - as is the case when looking at objects around you.

"[Nintendo] could employ parallax barriers, which put barriers in front of the screen so that each eye can see only every other column of pixels," speculated Dodgson. The downfalls with this tech, he went on to explain, is that the user would need to hold the 3DS at a particular distance to view the screen from a zone of optimum focus, or the image will blur.

You'll also notice a "fine grid of black bars" on the screen - the barriers that cover the pixels.

He goes on: "It could employ Hitachi's micro-lens array: which works just like the lenticular system," he said, referring to the lenticular tech explained in our detailed report on the 3DS yesterday. Here's more on Hitachi's display.

Dodgson told CVG yesterday: "Nintendo is likely to use lenticular technology," explaining that the lenticle tech required "can be made cheaply as a single sheet of die-cast plastic that can be pasted in front of the screen".
