Stroop Test System Using Gaze Position for Objective Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Stroop tests require expertise and specialized materials, leading to complexity and variability in results due to oral responses and subjective scoring.
Innovation Solution
A method using gaze position information to evaluate subjects on a test image with a test problem area and response area, where incorrect choices include a distractor capable of influencing the subject due to the Stroop effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional Stroop tests use oral responses and manual scoring, then the test can be administered with simple materials, but the evaluation becomes subjective and varies between examiners
Solution Approach 1:
The patent replaces the mechanical system of manual scoring and oral responses with an automated computer-based system that captures screen images and automatically evaluates responses by comparing them against correct answers, eliminating examiner subjectivity while maintaining test simplicity
Solution Approach 2:
The patent uses screen captures (copies) of the test display as the actual test medium, replacing physical test sheets. This allows the test to be administered through standard display devices without specialized materials, while the automated image comparison ensures consistent evaluation across all subjects
2Measurement precision
If conventional Stroop tests require specialized test sheets and examiner training, then accurate evaluation can be achieved, but the complexity of preparation increases
Solution Approach 1:
The system performs self-evaluation by automatically comparing captured screen images against stored correct answers, eliminating the need for examiner training and specialized preparation while maintaining evaluation accuracy through automated image recognition and comparison algorithms
Solution Approach 2:
The patent creates a universal test system that can be administered through any standard display device without requiring specialized test sheets or examiner expertise. The same software platform handles test presentation, response capture, and evaluation across different settings, reducing preparation complexity while maintaining precision
3Ease of operation
If oral responses are used in conventional Stroop tests, then the test can be administered verbally without writing materials, but scoring becomes time-consuming and variable
Solution Approach 1:
The patent replaces the manual scoring process with automated computer-based evaluation that instantly compares captured responses against correct answers, eliminating the time-consuming manual scoring process while maintaining ease of verbal response administration
Solution Approach 2:
The system continuously captures screen images during the test and performs real-time or immediate post-test evaluation, eliminating idle time between test administration and scoring. The automated process allows continuous processing of multiple subjects without the delays inherent in manual scoring

AI summary
A Stroop test method indicates an evaluation of a subject based on gaze position information indicating a position of a gaze of the subject on a test image (S102 to S105). The test image includes a test problem area that displays a test problem to be given to the subject and a response area that displays a plurality of choices including a correct choice and one or more incorrect choices for selection by the subject to answer the test problem by gazing. The one or more incorrect choices include a distractor choice capable of influencing the subject due to the Stroop effect.
