Information Processing for Cartesian Figure Scoring With Reference Figures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic scoring systems for problems requiring drawing of figures on a Cartesian coordinate system impose restrictions on the degree of freedom of drawing, leading to ineffective measurement of examinees' understanding and potential errors in setting scoring criteria.
Innovation Solution
An information processing apparatus and method that generates scoring criterion information based on user-drawn figures in a Cartesian coordinate system, allowing for the definition of scoring criteria through reference figures displayed on a display, enabling accurate and flexible scoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a restriction is imposed on the degree of freedom of drawing in answering, then automatic scoring with simple scoring criteria can be realized, but the effectiveness of measuring examinees' understandings of problems is reduced
Solution Approach 1:
The patent changes the parameter of scoring criterion representation from numerical coordinate ranges to visual reference figure boundaries. This allows the scoring system to evaluate whether drawn figures intersect with reference figure boundaries, providing a more intuitive and flexible method that maintains automatic scoring simplicity while improving measurement effectiveness by allowing greater drawing freedom.
2Measurement precision
If the degree of freedom in answering is increased, then examinees' understandings can be measured more effectively, but conventional methods of specifying scoring criteria by user input of numerical values are error-prone and troublesome
Solution Approach 1:
The patent replaces the mechanical input method of numerically specifying coordinate ranges with a visual display method where reference figures are shown on a display device. Users can visually identify and specify boundaries by interacting with displayed reference figures rather than manually inputting numerical coordinates, thereby eliminating input errors and simplifying the operation of setting scoring criteria.
Solution Approach 2:
The patent introduces reference figures as an intermediary between the scoring criteria definition and the evaluation process. These reference figures serve as visual mediators that translate complex numerical boundary specifications into intuitive graphical representations, making it easier for users to define and understand scoring criteria without dealing with error-prone numerical input.
3Adaptability or versatility
If conventional methods of specifying scoring criteria by user input of numerical values are used, then scoring criteria can be set, but errors are likely to occur and the process is troublesome
Solution Approach 1:
The patent replaces manual numerical input with visual display and interaction methods. Reference figures are displayed showing boundary lines, and users can specify scoring criteria by interacting with the visual representation rather than typing coordinates. This substitution eliminates transcription errors and improves reliability while maintaining flexibility in defining scoring criteria.

AI summary
An information processing apparatus includes a processor that executes a program stored in a storage and generates scoring criterion information. The scoring criterion information is referenced in a scoring process of an answer figure to a problem that requires drawing of a figure in a Cartesian coordinate system. The Cartesian coordinate system is a coordinate plane or a coordinate space. In response to a reference figure being drawn in the Cartesian coordinate system based on a user operation, the scoring criterion information including information on a scoring criterion determined based on the reference figure is generated. The Cartesian coordinate system is displayed on a display.
