Dynamic Question Selection for Video Content Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content delivery methods lack flexibility and effectiveness in adjusting content during coaching, as they rely on simple keyword identification and are not tailored to individual users, failing to assess the depth and breadth of user understanding.
Innovation Solution
A system and method that dynamically selects and presents questions based on semantic analysis of video content, adjusting timing and complexity according to user interaction, providing additional content upon correct answers and simpler questions upon incorrect ones, to ensure effective comprehension and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple keyword identification is used for content delivery, then the system is easy to implement, but the system lacks flexibility and effectiveness in adjusting content to individual users
Solution Approach 1:
The system dynamically adjusts content delivery by transitioning from static keyword identification to dynamic semantic analysis. The coaching system continuously evaluates user responses and modifies subsequent content presentation in real-time, making the system adaptive to individual user needs while maintaining manageable complexity through automated semantic processing.
Solution Approach 2:
The system changes the parameter of content analysis from simple keyword matching to comprehensive semantic concept evaluation. By altering how content is processed (from surface-level keywords to deep semantic understanding), the system achieves greater adaptability without proportionally increasing complexity, as the semantic analysis framework provides structured evaluation criteria.
2Measurement precision
If semantic analysis is used to dynamically select questions, then user comprehension is improved, but the processing time and system complexity increase
Solution Approach 1:
The system performs preliminary semantic analysis of content during the content delivery phase itself, extracting key semantic concepts and generating potential assessment questions in advance. This preliminary processing reduces the time required during actual user interaction, as the heavy lifting of semantic understanding occurs before user responses are needed, thereby maintaining high assessment accuracy while reducing perceived processing time.
Solution Approach 2:
The semantic analysis process operates continuously throughout content delivery rather than as a separate batch process. As content is delivered, semantic concepts are identified and assessed in real-time, allowing the system to maintain continuous engagement with the user while accumulating assessment data, thus improving measurement precision without creating discrete time delays.
3Reliability
If content is delivered without interactive assessment, then the delivery process is simple and fast, but user understanding and retention are not ensured
Solution Approach 1:
The system implements continuous feedback loops where user responses to semantic-based assessments are immediately evaluated and used to adjust subsequent content delivery. This feedback mechanism ensures knowledge retention by identifying understanding gaps and providing targeted remediation, while the automated nature of the feedback process minimizes disruption to content delivery speed, maintaining productivity through efficient response evaluation and adaptation.

AI summary
This disclosure describes a system that delivers content (e.g. multimedia video), and analyzes and aggregates feedback of a user viewing the content. The user may interact with the multimedia video in the form of answering questions which are dynamically placed between video segments. The system may determine the response type of the user for a given question. The system may handle both positive and negative responses (e.g. correct and incorrect responses to questions). The system may help the user navigate the segments of the video.
