diagonal flat screen

lying down near a large screen watching the Mondial got me thinking
  [vote for,

I had an eye opening experience watching a soccer match while lying down below a large screen.

1. The players seemed to be weirdly flat and short.

2. I had to move my eyes to follow the ball from one side of the field to the other, and as it got further and closer.

Putting the two together made me realize that if I watched a flat screen laid out before me instead of it being sitting up blocking my view I would have the benefit of exercising my eyes, moving them and focusing them to near and far, instead of passively watching a 2d screen and trying to imagine the 3d experience.

What is needed of course is to adjust the scene for that point of view so to speak.

It's all a matter of perspective. https://www.starwar...-hope-opening-crawl

       So mount the flat screen on the ceiling with one end on a tilt mechanism to adjust viewing angle to the number of pillows you are using?

       Easy to prototype with a projector

       I don't think it's the change in focus you need so much as a distant focal point. Your screen needs to be far away or 40 meters long.

       >[Voice] ...needs to be far away. I don't think so. If you have a person running away, and your eye has to change focus to see the far end of the screen that is simulating exactly what happens at great distances. And its easier to do with a screen that is laid out from 1 cm to 3 meters away... Try it.
