I am hoping that the method FDev use to minimise nausea is VR blinkers. This is because we can then have an option to change the amount our peripheral vision is cut.

Blinders work well in Google Earth. I wouldn't mind blinders as an adjustable option if ED space legs uses free locomotion.
Whatever the locomotion, I hope space legs is not first-person pew pew in space. I'd rather have space legs be exploration type stuff such as walking around the ship, exploring wrecked ships and repairing things.
