Video Importance Degree Tracking via Viewer Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Senders in video lectures face difficulty in identifying scenes that viewers find valuable or interesting, as existing technologies lack effective methods to determine and analyze participant engagement during video playback.
Innovation Solution
An information processing apparatus that includes a receiving unit for operations on video, an associating unit to link operations with play locations, and a setting unit to assign an importance degree based on participant interactions, generating an 'importance degree' of video content by tracking participant interest through operations like noting, favoriting, and testing during video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video content is provided to viewers without interaction tracking, then the system is simple and easy to operate, but the sender cannot recognize which scenes viewers are interested in
Solution Approach 1:
The system implements feedback by collecting viewer operations (notes, favorites, tests) during video playback and using this information to generate importance degrees for different video sections. This feedback loop enables the sender to understand viewer interest without significantly increasing system complexity, as the feedback mechanism leverages existing video playback infrastructure.
Solution Approach 2:
The server acts as an intermediary between the viewer and sender, collecting and processing viewer operations. The server generates importance degree information based on aggregated viewer interactions and provides this processed information to the sender, eliminating the need for complex tracking systems at either end.
2Measurement precision
If detailed operation tracking is implemented to identify important video scenes, then viewer interest recognition is improved, but the system complexity and data processing burden increase
Solution Approach 1:
The system transforms detailed operation data into a simplified parameter - the importance degree - which quantifies viewer interest in different video sections. By changing the parameter from raw operation logs to aggregated importance scores, the system achieves precise measurement of scene importance while reducing data processing complexity.
Solution Approach 2:
Instead of analyzing every detailed operation individually, the system creates a simplified copy or representation of viewer interest through importance degree values. This abstraction preserves the essential information about viewer preferences while significantly reducing the complexity of data processing and analysis.

AI summary
An information processing apparatus includes a receiving unit that receives, during or after reproduction of a video, a predetermined operation with respect to the video, an associating unit that associates the received operation with a reproduction location where the received operation has been generated in the video, and a setting unit that sets in response to the received operation an importance degree of the reproduction location associated with the received operation.
