Speaker Queue Mechanism for Video Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current web conferencing systems face challenges in determining who is speaking in large groups, leading to an undesirable user experience, and lack effective methods for subdividing participants into breakout groups, which can disrupt the flow of discussions and be burdensome for organizers.
Innovation Solution
A virtual conferencing system that utilizes a speaker queue mechanism where participants can request and gain access to the center of attention by holding a 'queue key,' and allows for the formation of breakout groups based on user profile information and moderator input, enabling efficient management of discussions and group interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the system selects the loudest speaker to be prominently displayed, then the speaker identification is automatic, but frequent transitions occur resulting in undesirable user experience
Solution Approach 1:
The system requires speakers to raise their hand in advance before being selected for prominent display. This preliminary action creates a queue of willing speakers, allowing the system to select from pre-registered candidates rather than reacting to sudden volume changes, thereby stabilizing speaker position transitions
Solution Approach 2:
The system provides visual feedback by displaying a raised hand indicator to show which participants are ready to speak. This feedback mechanism allows the system and other participants to see the speaker queue status, enabling more controlled and stable speaker transitions based on explicit participant intent rather than automatic volume detection
2Ease of operation
If the meeting organizer manually chooses who is provided with the central speaker position, then speaker positioning is controlled, but friction is introduced to the free flow of discussion and burden on the organizer increases
Solution Approach 1:
Participants self-register to speak by raising their hands, which automatically adds them to the speaker queue. This eliminates the need for the organizer to manually select speakers, reducing organizational burden while maintaining controlled, orderly speaker transitions that preserve discussion flow
Solution Approach 2:
The speaker queue acts as an intermediary mechanism between participant intent and prominent display selection. Rather than direct organizer control or automatic volume-based selection, the queue system mediates the process by collecting participant requests and managing them in an orderly fashion, balancing control with ease of operation
3Adaptability or versatility
If participants are subdivided into breakout groups, then group discussions are facilitated, but the flow of discussion is disrupted and organizational complexity increases
Solution Approach 1:
The system automatically segments participants into separate breakout group video conferences based on organizer specifications. This segmentation allows multiple simultaneous group discussions while maintaining centralized control through the queue system, managing complexity through automated division rather than manual coordination
Solution Approach 2:
The speaker queue system serves multiple functions: it manages speakers in the main conference, manages speakers in each breakout group, and can transition speakers between different conference contexts. This multi-functionality reduces organizational complexity by using a single unified mechanism across different group configurations

AI summary
A virtual conferencing system is described for implementing a speaker queue. For example, one embodiment of the virtual conferencing system comprises: a plurality of clients, each of the clients comprising state management logic to maintain a current state of a virtual conference; a virtual conferencing service to establish audio and/or video connections between the plurality of clients during the virtual conference, the virtual conferencing service further including a state synchronization service communicatively coupled to the state management logic on each client to ensure that the current state of the virtual conference is consistent on each client; wherein the current state on each client includes a speaker queue comprising an ordered set of participants to be designated as current speakers during the virtual conference, wherein participants are added to the speaker queue in response to input provided by the participants indicating a desire to be a current speaker, wherein one or more participants towards the top of the speaker queue are designated to be current speakers, wherein participants are initially added to the bottom of the speaker queue and are moved towards the top of the speaker queue as other participants are removed from the top of the speaker queue; a virtual conferencing graphical user interface (GUI) to display a video stream of one or more current speakers within one or more current speaker regions, the virtual conferencing GUI further providing a visual representation of the speaker queue to each of the participants, the visual representation comprising an ordered representation of each of the participants in the speaker queue.
