I worked at a company that had a Cisco telepresence machine on wheels. You had to make sure it was plugged into a certain color Ethernet wall jack for it to work but every room had one. You could reserve it and then wheel it to the conference room you wanted.
That's nothing like a Cisco telepresence room. You have to have used one to understand. It's nothing too sci-fi -- not floor to ceiling curved displays or whatnot -- but just the multiple large TVs all in a curved setup on the other side of a curved table makes a huge difference.
And a standardized wall color and camera location, so that everyone that joins in from another telepresence room blends in as if they were really there.
It would seem like they relaxed rules about what's in the background. But then, my knowledge is from a Telepresence room having been setup at a previous employer somewhere between 10 and 15 years ago (and I wasn't directly involved).
Getting off topic here, but this makes me think of what can be seen now in some Japanese programs because of social distancing measures. I don't know what kind of setup they have, but in some programs, from the spectator's perspective, you see people lined up behind a table, but some of them are actually on large monitors that make them appear at the right size. The interesting thing is that the ones on monitors act like if they were actually there, turning their head in the direction of the person speaking.
