During Teams meetings you can now designate a signer, they will stay center stage on your screen as long as their video is turned on.
Note: Microsoft does not provide sign language interpreters for meetings. Sign language interpretation should be arranged in advance by meeting organizers or participants.
The signer will be identified in the meeting by a hand symbol next to their name.
At the top of the meeting, window click More… Accessibility then Manage Signers.
Here you can select your signer.
Sign Language view is a personal setting and only changes your view of the meeting.
If you want to identify a sign language interpreter that everyone sees in a specific meeting then it is best to use the Spotlight option.
To Spotlight a colleague, right click on their video then click Spotlight.
