Access checks
Before entry, Classroom checks the user’s school, event access, role, admission, available capacity, removal status, and recording notice. The resulting camera, microphone, and presentation permissions reflect the event settings and any participant-specific changes made by a manager.Main controls
The bottom control bar contains the most frequently used actions:- microphone
- camera
- present or stop presenting
- speaker mute for the local listener
- leave room
Participants and moderation
Hosts and moderators can, subject to role precedence:- mute one user’s currently published microphone or camera;
- mute all controllable participants’ microphones or cameras;
- allow or prevent one user from publishing audio, video, or screen share;
- reset the user to event defaults;
- lower a raised hand;
- remove and later reinstate a participant;
- change live event-wide microphone, camera, screen-share, chat, raise-hand, and waiting-room settings.
Chat and raise hand
Classroom saves chat messages so the event can retain its conversation history. The UI supports replies, edits, deletions, and loading older messages. Raise hand is also a Kralis participant state. A user controls their own hand, and managers can lower it. Both features can be disabled for the live event.Presentation behavior
Classroom has two presentation sources:Native whiteboard presentation
The presenter selects an attached board. Followers switch to the board view and see the active editor’s drawing and cursor. A viewer can leave follow mode and return later. The presenter’s camera can remain visible as picture-in-picture.Screen sharing
The browser prompts the presenter to choose a screen, window, or tab. Followers see the shared content, and the presenter camera can remain visible as picture-in-picture. Only one authoritative presentation source is active for a session. Replacing an existing presentation requires confirmation. Native board presentation is intentionally separate from screen sharing. Use native presentation for efficient live board viewing. Use screen sharing when the board or another application must be captured in a recording.Network and constrained devices
Classroom adjusts video delivery to the available connection. Network indicators use quality colors and a small percentage estimate. The elapsed timer is always visible; scheduled rooms also show remaining time. On a slow network or lower-end device:- turn off the local camera;
- enable low-bandwidth mode under More;
- avoid an unnecessary screen share;
- prefer the native whiteboard presentation when it does not need recording;
- close other camera-using tabs and applications.
