I have almost similar perception about video meetings aur classes. for last couple of month I am conducting classes online but I can feel that it's not engaging that much like like classes. in those days I was able to interact with them more freely and with attitude body language I could talk to them but here I can feel that I am just talking to myself. And there is nothing hand movement except a very few movement. My Idea is about similar to your idea that is online is not much interactive than physical classes. My new learning form your post is 50% is about body language which is great
