That's actually a great idea for a niche app. Could probably work for seasickness and carsickness as well.

It was inspired by motion sickness prevention glasses I heard about. They are hollow with water inside halfway to provide a horizon that reflects real motion. I think the perk to the VR thing is to be able to watch movies or read books without that little line getting in your way. But I don't know how pronounced that line is.

Edit: Interesting, the glasses actually have hollow rims with a blue fluid.

It seems like the kind of thing a small number of people would be interested in, but they'd be happy to spend a lot if it actually works.

I wonder if the smallest delay or lag rendering this horizon line would make things even worse. I guess this thing needs to be very timely.
