Or maybe not Discovery, but it was some show talking about some new technology for the US army or something. I saw it quite a while ago but only remembered about it recently.
Anyway, one of the things featured was this camera that's attached to the gun and to a something you wear on your head which covers one of your eyes. The reason for this is, instead of sticking your head (or whole body in UT) out in the open to see if there are enemies, you could just stick the gun out and see the camera through one of your eyes.
I believe this could be implemented by splitting the screen in half and by pressing a key, one side will be replaced by whatever the camera is seeing, and your controls will move the view for that camera. Just press the key again to resume control of your character.
