Abstract: Examples provide an accessibility manager enabling a persistent floating secondary stage for presentation of user-configurable content during a video conferencing meeting. A primary stage is provided during each video conferencing meeting. The primary stage includes a roster of meeting attendees and an area for displaying shared content. The user creates configurable settings which are used at every meeting to generate a customized secondary stage. The secondary stage is an overlay which persists on the user interface even if the primary stage is minimized as the user multi-tasks during the meeting. The secondary stage displays video feed for one or more selected meeting attendees, such as an interpreter. When an interpreter speaks on behalf of the user, the user receives the active speaker attribution. The configurable settings permit the user to control the secondary stage video feed quality, sizing, aspect ratio, display location, captioning, role designation and active speaker designation.
