Most remote proctored tests already work this way. Web cams on, starts with a 360 recording of your work area to ensure there is nothing to reference / cheat with, detects if your eyes move off screen, scans and monitors all processes running on your computer. In addition, a remote “viewer” can see your camera and hear your audio and chat with you if anything is suspicious.

I thought it was pretty insane when I first saw my nephew take a test like this, but it seems they’re already fairly well prepared.
