It looks like UI-View users could e.g. use the "numbered circle" symbol
(or any of the other "numbered" symbols) with an "O" overlay to indicate
an operator present.

Of course, to be meaningful, the user would have to remove the "O"
overlay if they were going to step away from the keyboard for more
than a moment.
