Sensory Trait Collection Under Controlled Light Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with biased visual cognitive function, such as those with Learning Disorder or Irlen Syndrome, often remain unaware of their visual perception biases, and existing self-check tests are subjective and difficult to administer without specialized knowledge.
Innovation Solution
A sensory traits information collecting method and device that presents viewed objects under controlled light environments, using white and predetermined light conditions, to collect and analyze sensory traits information through a Likert scale and SD method, eliminating subjectivity and the need for specialized knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-check tests are used for early detection of visual cognitive biases, then accessibility and ease of operation are improved, but measurement precision and reliability deteriorate due to subjectivity
Solution Approach 1:
The patent introduces an intermediary system consisting of a light environment generation device and a standardized viewed object that mediates between the subject's visual perception and the assessment process. This intermediary setup eliminates the need for specialized knowledge by providing controlled, reproducible viewing conditions while collecting standardized responses from subjects, thereby resolving the contradiction between ease of operation and measurement precision
Solution Approach 2:
The patent changes the parameter of light environment (from uncontrolled natural lighting to controlled spectral distribution and luminance) to improve measurement precision. By standardizing lighting parameters and viewed object characteristics, the system achieves objective assessment while maintaining ease of operation through automated data collection and analysis
2Measurement precision
If specialized personnel are used for assessment of visual cognitive biases, then measurement precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent enables the assessment system to serve itself by providing standardized viewed objects and controlled light environments that guide subjects through the assessment process without requiring specialized operators. The system automatically collects responses and generates assessments, eliminating the need for specialized personnel while maintaining measurement precision through standardized procedures
Solution Approach 2:
The patent segments the assessment process into distinct components: light environment generation, viewed object presentation, subject response collection, and automated analysis. This segmentation allows each component to be independently optimized and standardized, reducing the need for specialized knowledge while maintaining diagnostic accuracy

AI summary
A sensory traits information collecting method includes: a first viewed-object presenting step of presenting one or more viewed objects (30) including a predetermined visibility element (31, etc.) to a subject in a white light environment in which white light (L0) is incident on a retina (R) of the subject; a predetermined light environment creating step of creating a predetermined light environment in which predetermined light (L1) different from the white light (L0) in at least one of spectral distribution and luminance is incident on the retina (R) of the subject; a second viewed-object presenting step of presenting the viewed object (30) to the subject again in the predetermined light environment; an information reception step of receiving sensory traits information related to the way of seeing of the viewed object (30) in the first viewed-object presenting step and the second viewed-object presenting step; and a collecting step of collecting the sensory traits information received from the subject.
