Learning Assistance Using Operation History for Correct-Answer Understanding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional learning assistance devices are unable to fully analyze user hesitation from input speed alone, leading to insufficient learning assistance tailored to individual users.
Innovation Solution
A learning assistance device that includes an answer acquisition unit, a scoring unit, an operation history information acquisition unit, and an understanding level estimation unit. The device analyzes operation history information, such as changes in answer content and answer duration, to estimate the user's level of understanding for each question, even if the answer is correct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only input speed is used to estimate user understanding, then the analysis is simple and quick, but the estimation accuracy is insufficient
Solution Approach 1:
The patent segments the analysis of user understanding into multiple independent components: input speed analysis, answer content change analysis, and hesitation detection. Each component processes specific aspects of user behavior separately, then combines them to achieve comprehensive and accurate understanding level estimation without overwhelming complexity
Solution Approach 2:
The patent transitions from one-dimensional input speed analysis to multi-dimensional analysis by incorporating answer content changes and hesitation patterns as additional dimensions. This dimensional expansion enables more accurate understanding level estimation while maintaining manageable system complexity through structured processing of each dimension
2Adaptability or versatility
If only incorrect answers are analyzed, then the processing is efficient, but the learning assistance is insufficient for correctly answered questions
Solution Approach 1:
The patent creates a universal analysis framework that processes both correct and incorrect answers using the same comprehensive methodology. The system evaluates understanding level for all answer types by analyzing input speed, content changes, and hesitation patterns, making the learning assistance versatile and applicable to all questions while maintaining efficient automated processing
3Measurement precision
If comprehensive operation history information is collected, then the understanding level estimation is more accurate, but the data processing load increases
Solution Approach 1:
The patent extracts only the essential and relevant features from comprehensive operation history information: input speed metrics, answer content changes, and hesitation patterns. By selecting and processing only these critical elements rather than all available data, the system achieves accurate understanding level estimation while minimizing data processing load

AI summary
A learning assistance device 10 is a device that is applied to a system in which a user operates an information processing terminal to input answers to questions, and comprises an answer log reception unit 11, a scoring unit 12, an operation history information acquisition unit 13, and an understanding level estimation unit 14. The answer log reception unit 11 acquires answers to questions. The scoring unit 12 performs scoring on the basis of the answers acquired by the answer log reception unit 11. The operation history information acquisition unit 13 acquires history information about operations inputted by the user to the information processing terminal when answering the questions. The understanding level estimation unit 14 estimates the user's level of understanding for each question that has been scored as correct by the scoring unit 12, on the basis of the scoring results for the user's answer to each question and the user's operation history information acquired by the operation history information acquisition unit 13.
