@Number_one (the OP) already edited the original post about an hour after it was posted because he realized this.
That being said, eye trackers do exist so it can be replicated, it’s just not something that’s been done before because it’s a rather peculiar idea to begin with, and because eye trackers as gaming hardware isn’t commonplace yet (and is a rather unexplored field when it comes to being adapted for gaming).
Theoretically though, a tech demo utilizing Tobii Eye tracking (or something similar in nature) could replicate stereo parallax and peripheral vision. There’s not a huge demand for making advancements in eye tracking though, and even though something like the Vive Pro has eye-tracking, the Valve Index does not (afaik), which is unfortunate for eye-tracking enthusiasts.
