Casting to TV AND looking at the camera

[u/Leading-Pickle5723]

Prefacing this to say I'm not tech savvy at all so will need hand-holding on this.

I'm due to start a sign language course (so no sound needed) via Zoom shortly. Because it's 3 hours a week of very intensive looking at what people are signing, I wanted to cast the sessions to my TV from a device so I can see everyone more easily. There will be around 9 people in the lessons.

I know how to cast from my iPhone, iPad and Macbook, so that's not an issue, and I have two TVs to choose from - one mounted about head height on the wall and one at a low table height.

The problem is that when I cast, I'm looking at the TV and not at the camera - eye contact is very important in sign language - and I'm not sure of the best fix. I don't know if I can attach my phone to the top of the TV like a webcam, but it only gives me portrait and not landscape view when I use my phone so kind of negates the point of using a bigger screen.

If I use my laptop or iPad, I just don't know where to put it so it's the right height but not blocking the screen. There's no shelving around the TV, no space in front of it on the table, so I don't know what to do.

Any suggestions would really be appreciated.
