What exactly do you mean by this? Are you saying that right now, the most popular use of VR headsets is for pornography? Or are you speculating on how VR headsets will be used in the future?
Yes, that's what I'm saying. It's a "dirty little secret". Most of it is VR video at the moment but apps are growing quickly. New titles appearing on steam all the time and appearing on the top 10 selling titles.
I‘m a long time VR user and except for some concepts I haven’t seen anything like what you describe, certainly not that popular.
They even provide scripts for your automated toys (I don't own one but i'm really curious about them.) to sync with the videos.
