Stroke Data Display Control for Visual Answer Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to determine whether a user has correctly answered in the expected state without reproducing the inputting process, making it difficult for graders to assess student performance accurately.
Innovation Solution
A computer system that acquires stroke data, determines if the data was input in a particular state, and controls the display state based on this determination, using a processor and memory to execute programs that analyze and render the data with different colors for correct and incorrect strokes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the inputting process is reproduced to determine whether the student answered correctly, then the assessment accuracy is improved, but the complexity of the system increases
Solution Approach 1:
The patent extracts only the essential information needed for assessment from the complete inputting process. Instead of reproducing the entire process, it identifies and extracts key features such as stroke order, stroke shape, and completion status, which are then used for determination. This extraction approach maintains assessment accuracy while avoiding the complexity of full process reproduction.
Solution Approach 2:
The patent creates a simplified copy or representation of the inputting process rather than reproducing the full process. It generates determination data that captures the essential characteristics needed for assessment (such as whether strokes were made in correct order and whether the answer is complete) without requiring the complex infrastructure of full process reproduction.
2Loss of information
If the complete inputting process is reproduced, then the information about student performance is improved, but the time required for assessment increases
Solution Approach 1:
The patent extracts only the critical information elements from the inputting process that are necessary for assessment. It identifies key data points such as stroke order sequence, stroke completion status, and answer finality, extracting these specific elements while discarding redundant information. This extraction maintains information completeness for assessment purposes while significantly reducing processing time.
Solution Approach 2:
The patent performs partial action by conducting determination processing only on the essential aspects of the inputting process rather than analyzing the entire process in detail. It focuses computational resources on evaluating only the critical determination data (stroke order correctness, completion status) rather than reproducing and analyzing all aspects of the inputting process, thereby reducing assessment time while maintaining information quality.

AI summary
The present disclosure makes it possible to realize with ease whether a student has been able to answer a question in an expected state. A computer includes a processor and a memory storing a program that, when executed by the processor, causes the computer to acquire a plurality of pieces of stroke data, determine whether the pieces of stroke data have been input in a particular state, and control a display state when the pieces of stroke data are displayed based on a result of determining whether the pieces of stroke data have been input in the particular state.
