Dynamic Videoconference Layout Adaptation for Participant Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconferencing systems do not adapt their layout based on the number of participants at each location, leading to inefficient use of screen space and visual focus.
Innovation Solution
A method to determine the number of participants at each location during a videoconference, using facial recognition and audio analysis, and adjust the composite video layout dynamically to allocate screen space proportionally based on participant numbers, with an active portion for emphasis and scalable non-active portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed layout is used for videoconferencing, then the system is simple to implement, but the layout does not adapt to varying numbers of participants at each location
Solution Approach 1:
The videoconference layout is made dynamic by continuously monitoring participant numbers at each location and automatically adjusting the allocation of screen space. The system transitions from a static fixed layout to a dynamic adaptive layout that responds to changing participant configurations in real-time, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The system changes the parameter of screen space allocation based on the detected number of participants at each location. By varying the layout parameters dynamically according to participant counts, the system achieves adaptability without requiring complete system redesign, thus managing the complexity-adaptability trade-off.
2Loss of information
If screen space is allocated equally to all locations, then the layout is simple to generate, but locations with more participants receive insufficient visual representation
Solution Approach 1:
Instead of applying a uniform screen space allocation across all locations, the system applies local quality by allocating screen space proportionally based on the number of participants at each specific location. This ensures that locations with more participants receive greater visual representation, preventing information loss while maintaining automated layout generation.
3Loss of information
If the layout dynamically adjusts to participant numbers, then visual representation is optimized, but the processing complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting participant numbers and generating optimized layouts without requiring manual intervention. This automation handles the processing complexity internally while delivering optimized visual representation, resolving the contradiction between quality and complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring participant numbers and using this information to adjust the layout dynamically. This closed-loop approach optimizes visual representation based on real-time conditions while automating the complex processing required for adaptive layout generation.

AI summary
Determining a videoconference layout based on numbers of participants. Videoconference data may be received from a plurality of videoconferencing endpoints. The videoconference data may include audio and video. Information may be stored which identifies a number of participants at each videoconferencing endpoint. Video from each of the videoconferencing endpoints may be combined to form composite video. The composite video may include portions corresponding to each of the plurality of videoconferencing endpoints. A respective size of each of the portions may be based on the information identifying the number of participants at each videoconferencing endpoint. The composite video may be provided to videoconferencing endpoint(s) over a network.
