Here's the best set up I've used so far: 1) Get the cheapest iPad that supports the Apple Pencil. The 2018 non-Pro was this for me last I looked. 2) Get the Google Jamboard app (not the Jamboard hardware, it is not at all worth it). 3) Share the "jam" with yourself on a different device (a nearby laptop) 4) Screenshare the laptop. Things I think any virtual whiteboard scheme needs to have: 1) You need to be able to s…
1) ditto
2) join meeting from ipad (in addition to camera/mic device)
3) present screen from ipad
Then you can use any pencil app you like. I use one called "Coloring" that my kid uses. It's really simple and doesn't get in the way.
I presume the same would work for any other videoconf tool, eg zoom.
The benefit over your method is that you still have the additional headshot view, since you're joined to the meeting twice. Can the jam app not join a google meet "natively"?
It's not collaborative, in that any other participant can edit the drawing, so it doesn't answer the originally posed question. But I've found that for the most part, even in person, just one person really "drives" the whiteboard. With the tiny screen size afforded over video, you aren't really going to benefit much from having multiple people be able to edit anyway. For that kind of collaboration you really need 2-3 6' wide whiteboards in a large room.
I feel the benefit of having a second, independently presenting device for the whiteboard, while still being able to participate with your talking head view, outweighs (by far) the downside of only one editor.
