As a linguist, waving is a brilliant solution to bridge the sudden disappearance at the end of a video call: esp in a group, when you can see everyone's waving, you know they're all ready to leave

It's like standing up, picking up your coat/bag - transitional movements https://twitter.com/claremackint0sh/status/1263481311907504128
A gesture linguist (who I happen to videochat with a lot) agrees! https://twitter.com/superlinguo/status/1263696495800279040
One of the big differences with walking out of a meeting room vs a videocall is that you can still expect to see someone in the hallway after a physical meeting, which is not the case at all in videochat!

So we do need a fuller farewell, which a wave can accomplish!
As @kirbyconrod said very well a few days ago, linguists spend a lot of time telling people they're ok

If you're communicating differently in a different environment, it's ok to think, hey, maybe this is an entirely reasonable adaptation to circumstances! https://twitter.com/kirbyconrod/status/1262133963109232640
Yes! It's really exciting and excellent that we've all been converging on this great adaptation to bridging an awkward moment! https://twitter.com/BethSkw/status/1263907767259148288
Also a cool use of waving!

(I also use the parallel chat function for acknowledging new arrivals, but the chat is more prevalent in some circumstances than others) https://twitter.com/ElizdAnjou/status/1263908493972721675
There's also earlier research on paired exchanges for closing a telephone convo:

Alright
Right
Okay
Well
Good then
Better let you go
Bye now
Bye
Bye

This looks a bit strange written out, but it's a bridge instead of just hanging up abruptly! https://twitter.com/DrewHicken/status/1263908692518473730
Exactly, and waving also works great even if some people are on mute! https://twitter.com/PsycheReady/status/1263908830108200962
If you want to think more about gesture linguistics, we did an episode of @lingthusiasm about it!

(It's a special video episode, so you can see the gesture, but also available in regular podcast audio form and as a written transcript)
