Evaluation Device for Object Identification Ability Using Response Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for objectively evaluating temporal lobe function during visual recognition are burdensome for test subjects due to the use of large devices and prolonged measurement times, which restricts their applicability in assessing personality and mental states.
Innovation Solution
A device and method that includes a display unit showing target and non-target objects, an input processing unit determining object selection, and an evaluation unit assessing response time to objectively evaluate the ability to identify objects, reducing subject burden by using a portable and user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If brain wave measurement or fMRI is used to quantitatively grasp brain characteristics, then measurement precision is improved, but device complexity increases and ease of operation deteriorates due to large device size and physical restraint requirements
Solution Approach 1:
The patent extracts the essential measurement function from complex medical imaging equipment (fMRI, brain wave devices) and implements it through a simplified computer-based system that displays images and measures response times, eliminating the need for large-scale hardware while maintaining evaluation capability
Solution Approach 2:
The patent creates a functional copy of brain activity measurement by using response time to object selection as a proxy indicator, replacing direct neural measurement with behavioral observation that correlates with temporal lobe function
2Measurement precision
If brain wave measurement or fMRI is used to quantitatively grasp brain characteristics, then measurement precision is improved, but ease of operation deteriorates due to prolonged measurement time and physical restraint
Solution Approach 1:
The patent removes the time-consuming and restrictive aspects of traditional brain measurement by extracting only the essential evaluation function and implementing it through simple image display and response time measurement, eliminating physical restraint requirements
Solution Approach 2:
The patent creates a simplified version of brain activity assessment that copies the measurement goal (temporal lobe function evaluation) but achieves it through everyday computer interaction rather than specialized medical equipment

AI summary
The present disclosure provides an evaluation device for evaluating a test subject's ability to identify an object, the evaluation device including: an input unit that receives input of the test subject; a display control unit that displays, on a display device, a test screen including a target object that the test subject should select and a non-target object that the test subject should not select; an input processing unit that determines whether or not a target object is selected on the basis of input of the test subject received by the input unit; and an evaluation unit that evaluates a temporal lobe function related to a visual recognition ability of the test subject on the basis of a response time required for the test subject to input when the input processing unit determines that the target object is selected.
