Sounds like you’re limiting your view to work-related calls. If I could have real eye contact on personal calls, it would make a huge difference.
My current technique of looking just below the camera already makes a huge difference, and it’s only a hack to make it seem like eye contact for the other person.
I do half of that crap on personal calls too. Interestingly enough, I don't get those issues on phone calls! Or most audio only calls over the internet.
The underlying issue is the technical failures of video calling, not the social environment it's used in.
It is natural to look at the person and eye contact when talking to them. Hence we don't look at the camera, though I'm sure some people can and do this.
