I'd imagine it wouldn't improve the quality, but could improve your field of view within which you have working stereoscopic vision (e.g. past ~45 degrees looking left/right from your head's facing)

Seeing discussion of the paper earlier, I investigated the limits of my own vision, and noticed that beyond just my nose I can actually (barely) see the bridge of my brow, my cheeks, and even my mustache (significantly more so if I pucker my lips).

I'm wondering if virtual glasses, helmet mounted display elements, or other pieces would also help.
