Online Video Distribution Support System for Viewer Interest Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video call systems cannot determine whether viewers are interested in the content being distributed during the transition between slides, as they rely solely on slide direction and viewer gaze direction, failing to assess the correlation between the distributor's content and the viewer's interest.
Innovation Solution
An online video distribution support method and system that calculates the degree of interest of viewers by acquiring and comparing their line-of-sight positions with the distributor's line-of-sight position using captured images, employing convolutional neural networks for analysis and calculating a degree of interest based on similarity metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If line-of-sight information is used to determine viewer interest, then measurement precision of viewer engagement is improved, but device complexity increases due to multiple cameras and neural network processing
Solution Approach 1:
The patent introduces a server as an intermediary that centralizes the neural network processing and degree of interest calculation. The server receives line-of-sight information from multiple viewer terminals and distributor terminals, performs the complex CNN processing and similarity calculations, and returns results. This mediates the complexity away from individual terminals while maintaining high measurement precision through centralized advanced processing.
Solution Approach 2:
The patent replaces traditional mechanical/video-based attention assessment methods with neural network-based image processing. Instead of using simple video analysis or manual assessment, the system employs CNNs to detect line-of-sight positions and calculate degrees of interest, substituting mechanical/system-level complexity with intelligent algorithmic processing that achieves higher precision.
2Measurement precision
If multiple line-of-sight positions are tracked simultaneously, then measurement precision of content correlation is improved, but loss of information increases due to the complexity of processing multiple data streams
Solution Approach 1:
The patent implements feedback mechanisms where the server continuously receives line-of-sight information from multiple terminals, processes it through the neural network, calculates degrees of interest, and can use this information to provide feedback to distributors about viewer engagement. This feedback loop maintains high measurement precision by continuously updating the analysis while managing information flow systematically to prevent data loss.
Solution Approach 2:
The server is designed as a universal processing platform that handles multiple types of data simultaneously - line-of-sight information from multiple viewers, distributor content information, neural network processing, and degree of interest calculation. This multi-functional design allows the system to process multiple data streams efficiently without increasing individual component complexity, maintaining precision while managing information flow.

AI summary
An online video distribution support method is executed by an online video distribution support system including one or more computers connected to communicate with a plurality of viewer terminals used by viewers who view an online video. The online video distribution support method includes: displaying a video distribution screen including a material designated by a distributor that distributes the online video; acquiring information on a line-of-sight position of each of the viewers on the video distribution screen from each of the viewer terminals; detecting and acquiring a line-of-sight position of the distributor on the video distribution screen by using a captured image obtained by capturing the distributor; and calculating and outputting a degree of interest of each of the viewers based on the line-of-sight position of the corresponding viewer and the line-of-sight position of the distributor.
