A fancy enough camera system can give you a wide FOV and accurate distance indicators to everything on screen.

Parallax is one way we estimate distances, technology can do a lot better than "move head side to side to get a rough idea."

Now getting people used to wide FOV, that may be challenging. Find an FPS that lets you set the FOV to anything you want, set it to 180. After a couple of minutes you can get used to it. Beyond 180 it is hard! But even 190 or so is doable after a bit of practice.

Not sure how the general public would do with that though! (At what point has a high enough % of the general public played FPSs that such a UI could be gotten away with?)
