Virtual Meeting Summary Generation Through Decentralized Reaction Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual meeting systems face challenges in generating summaries of missed content during breaks in presence (BIP) due to privacy concerns, scalability issues, and computational burdens when relying on a central server for analyzing user reactions, especially when participants keep their video and audio muted.
Innovation Solution
A decentralized approach where local computing devices monitor and analyze user reactions during BIP events, transmitting only anonymized parameters to a central server for generating summaries, reducing the computational and storage burden on the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a central server analyzes user reactions to generate meeting summaries, then summarization accuracy is improved, but privacy protection deteriorates and server computational burden increases
Solution Approach 1:
The system divides the centralized analysis function into distributed local analysis units at each user device. Each device independently analyzes its own user's reactions and generates local summary data, which is then aggregated by the server. This segmentation maintains summarization accuracy while protecting user privacy by keeping raw reaction data local.
Solution Approach 2:
The patent introduces an intermediary layer that processes user reaction data before it reaches the central server. Local devices act as intermediaries, converting raw reaction data into anonymized statistical representations that preserve summarization quality while eliminating privacy risks associated with transmitting sensitive user data.
2Measurement precision
If a central server analyzes all user reactions, then summary quality is improved, but server storage and computational burden increase
Solution Approach 1:
The computational workload is segmented from the central server and distributed to individual user devices. Each device performs local analysis of its user's reactions, generating only aggregated statistical data for server processing. This dramatically reduces server computational burden while maintaining summary quality through distributed intelligence.
Solution Approach 2:
Each user device performs self-service analysis of its own user's reactions, eliminating the need for the central server to process individual user data. The devices autonomously generate local summary statistics and transmit only these aggregated results to the server, reducing server workload while preserving summary accuracy.
3Measurement precision
If video and audio are transmitted for all participants, then reaction analysis accuracy is improved, but bandwidth consumption and privacy protection worsen
Solution Approach 1:
The system extracts only the essential reaction data needed for analysis while discarding redundant information. Instead of transmitting full video and audio streams, each device extracts key reaction indicators (e.g., presence/absence, basic emotional states) and transmits only these minimal data sets to the server, maintaining analysis accuracy while minimizing bandwidth consumption.
Solution Approach 2:
The patent transforms reaction data from high-bandwidth formats (video/audio streams) to low-bandwidth parameter representations (statistical indicators, anonymized metrics). This parameter transformation preserves the essential information needed for reaction analysis while dramatically reducing the quantity of data transmitted over the network.

AI summary
Systems, methods and apparatuses are described for providing a summary associated with a virtual meeting. In response to detecting a break in presence (BIP) at a first computing device for a first user in the virtual meeting, each of one or more second computing devices participating in the virtual meeting and corresponding to at least one second user may be caused to locally monitor reactions of the corresponding at least one second user to the virtual meeting during the BIP. The server may receive one or more parameters associated with the locally monitored reactions and corresponding to a portion of the virtual meeting during the BIP. In response to determining to generate a summary associated with a corresponding portion of the virtual meeting during the BIP, based on the received one or more parameters, the summary may be generated and provided to the first computing device.
