Whiteboard Viewport Synchronization for Speaker-Led Conferences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conferencing software does not synchronize the viewports of conference participants, leading to distractions as participants struggle to keep up with different presenters discussing different aspects of a whiteboard, requiring manual scrolling to relevant portions.
Innovation Solution
A software platform uses audio-visual components to identify a current speaker and synchronize the viewports of following-along participants based on the viewport of a designated follow-along participant, allowing seamless whiteboard experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If viewport synchronization is not implemented, then each participant can independently view different portions of the whiteboard, but participants experience distractions and difficulty keeping up with different presenters
Solution Approach 1:
The system automatically synchronizes viewports based on speaker identification and follow-along participant selection, eliminating the need for manual viewport adjustment by participants. The whiteboard management system self-adjusts viewports based on detected triggers such as speaker changes, thereby resolving the contradiction between independent viewing and ease of operation.
2Adaptability or versatility
If manual viewport adjustment is required, then participants have full control over their view, but participant focus decreases due to distractions from manual navigation
Solution Approach 1:
The system pre-configures viewport synchronization by identifying follow-along participants and automatically adjusting their viewports in advance of when they need to view specific content. This preliminary setup eliminates the need for participants to manually navigate during presentations, maintaining both adaptability and focus.
3Reliability
If viewport synchronization is implemented, then participant focus is enhanced and distractions are reduced, but system complexity increases
Solution Approach 1:
The system introduces a mediator component that detects triggers (such as speaker identification and follow-along participant selection) and automatically manages viewport synchronization. This intermediary layer handles the complexity of coordination between multiple participants and presenters, thereby enhancing focus without requiring complex direct interactions between all system components.
4Productivity
If automatic viewport adjustment is used, then collaboration efficiency improves, but loss of information increases due to automated viewport changes
Solution Approach 1:
The system incorporates feedback mechanisms where follow-along participants can provide input about their viewport preferences and follow-along selections. This feedback loop ensures that automatic viewport adjustments align with participant needs, maintaining collaboration efficiency while preventing loss of important viewport context information.
Data Source
AI summary
A first conference participant of a conference that includes a whiteboard is identified. A first viewport into the whiteboard is identified. The first viewport is displayed at a device of the first conference participant. A second viewport is set based on the first viewport. The second viewport is displayed at a device of a second conference participant. The first conference participant may be identified based on a trigger associated with the first conference participant. The first conference participant may be identified based on speech in an audio stream received from the device of the first conference participant. The first conference participant may be identified based on an edit to the whiteboard received from the device of the first conference participant.
