When I'm meeting in person I can move around, I can look at whoever is the center of attention at the moment without having to care if someone is watching me, it's much more easy to tell if you are being watched or not and when to relax or not.

The parallel does not work, I don't think it's that hard to realise that a camera pointing at your face, showing how you look at any given moment to anyone that looks at you and you can't tell if they are looking at you or not is equivalent to an in-person setting where you are aware of your surroundings much more naturally.

I really don't know how to be more explicit than this about the major differences between in-person to a virtual meeting with cameras...
