3DS viewing angle - room for improvement?

The sweet spot exists because a different image has to be sent to each of your eyes. I don't think it's possible to make the sweet spot any bigger than the angle between your eyes without some crazy-sophisticated setup.

Exactly, every even pixel on the horizontal spectrum has light directed to the left, and every odd pixel directs it to the right; so the eye on the left doesn't pick up light from the odd pixels.

 

So it really is the distance between a person's eyes.

 

But either way, 3D is not required, but it does dramatically improve the visuals of the game - it makes things appear far more lifelike.
