We can do curved screens. The theoretical limit is we can cover the whole visual field.

- crazygringo 3y agoHow do you get the light into the inside edge when your nose is in the way, and the lenses for each eye would collide in the middle? How do you get the light into the outer edge without making the headset absurdly wide? Curved screens aren't the issue here. The issue is the lenses and light paths between the screens and eye. VR requires collimating lenses. Not just a screen, curved or not.
- saltcured 3y agoJust for the sci-fi fun of it, I'm trying to imagine the mechanism of the laser projector featured in Snowcrash. How about a microscopic lenticular array in a close-fitting shell over each eye (kind of like swim goggles) or even in a special contact lens. The goal is to have appropriate lenses in front of the pupil. This lens array can then be targeted by extremely precise laser projectors, exploiting the lenses to illuminate parts of the retina that would not otherwise be visible from the same projector location through a naked eye.
