Gallery View
Moderators will be able to see up to 25 videos at a time in gallery view. The number of videos will depend on the size of your screen and if you have the session menu or collaborate panel open.
In gallery view moderators can use the previous and next buttons to see all of their students. Moderators can also point to an attendee video and select the Attendee Controls to send them a private chat, promote a participant, mute the attendee, or remove the person from the session.
Gallery view is currently only available to moderators, Blackboard is looking to roll this out to students in the near future.
Speaker view is the default view when you join a collaborate session as a moderator. Select the change view button in the upper right of the screen to switch between views.
