Web Conference Preview Generation via Interaction-Based Key Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to adequately identify content in recorded web conferences that is of potential interest to users who did not attend the live session, leading to low engagement with recorded web conference content.
Innovation Solution
Automatically generating a preview of a web conference based on participant interactions during the event by selecting key frames with high interaction levels and generating a preview that showcases these frames, allowing users to determine if they want to view the full recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users access recorded web conferences without preview content, then the full recording content is available, but user interest and engagement remain low
Solution Approach 1:
The system performs preliminary analysis of web conference recordings to automatically generate preview content before users access the full recording. The preview includes key frames, captions, and interaction highlights that are prepared in advance based on interaction data, allowing users to make informed decisions about viewing the complete recording.
Solution Approach 2:
The patent introduces an intermediary preview system that mediates between the full recording content and user interest. The preview acts as an intermediate layer that summarizes and highlights relevant portions of the recording using key frames, captions, and interaction data, enabling users to efficiently assess whether the full recording contains content of interest to them.
2Loss of information
If the entire web conference recording is presented to users, then complete content is available, but users cannot efficiently identify topics of interest
Solution Approach 1:
The system extracts key information from the full web conference recording by identifying and isolating significant key frames, relevant captions, and notable interaction moments. This extraction process separates the most important content elements from the complete recording, presenting them in a condensed preview format that enables users to quickly identify topics of interest without reviewing the entire recording.
Solution Approach 2:
The patent segments the continuous web conference recording into discrete, analyzable units including individual key frames, caption segments, and interaction events. By dividing the recording into these segmented components and analyzing them separately, the system can identify and highlight specific portions of interest, allowing users to efficiently locate relevant content without examining the full unbroken recording.
3Reliability
If no preview is provided for recorded web conferences, then the system is simple, but users are unaware of valuable content in recordings
Solution Approach 1:
The system employs self-service mechanisms where the web conference recording data itself provides the information needed for preview generation. Interaction data, captions, and key frames that are already captured during the live conference are automatically analyzed and reused to create the preview, eliminating the need for separate manual content creation or additional complex analysis systems.
Solution Approach 2:
The patent applies parameter changes by transforming existing recording data into different formats and representations suitable for preview display. Key frames are selected and resized, captions are processed and highlighted, and interaction data is converted into visual indicators. These parameter transformations enable the creation of informative previews using existing data without requiring fundamentally new system components.
Data Source
AI summary
Techniques are disclosed for auto-generating a preview of a web conference based on participant interactions during the web conference. A web conference is recorded and includes a shared presentation and participant interactions. Key frames of the shared presentation are identified. During the web conference, differing amounts of interaction between the participants occurred during presentation of the respective key frames. The technique selects a subset of the key frames to include in the preview based on the differing amounts of interaction between the participants that occurred during presentation of the key frames and generates the preview using the subset of key frames. An example preview displays a sequence of key frames in which each key frame is displayed for a few seconds.
