Diagnosis Support Device Gaze Tracking for Developmental Disorder Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for diagnosing developmental disorders in 18-month-olds are inadequate due to the subject's tendency not to gaze at stationary objects, leading to reduced diagnostic accuracy.
Innovation Solution
A diagnosis supporting device that includes an imaging unit, an eye gaze detector, a gaze point detector, and an output controller to display a diagnostic image composed of a natural image superposed with a pattern image, allowing for improved detection of gaze points and diagnostic accuracy.

Engineering Contradiction Analysis
1Measurement precision
If conventional gaze point detection methods are used on 18-month-old subjects, then the detection process can be performed, but the diagnostic accuracy is reduced because subjects with developmental disorders do not gaze at stationary objects
Solution Approach 1:
The patent transforms the static display into a dynamic system by detecting the subject's gaze point in real-time and moving the stimulus object to follow the gaze trajectory. This dynamic adaptation ensures that subjects with developmental disorders who avoid stationary objects can still engage with the stimulus, thereby improving both gaze detection reliability and diagnostic accuracy
Solution Approach 2:
The system changes the positional parameter of the stimulus object based on detected gaze coordinates. By dynamically adjusting the stimulus position to match the subject's gaze point, the system adapts to individual viewing behaviors and overcomes the limitation of stationary object avoidance in developmental disorder subjects

AI summary
A diagnosis supporting device according to an embodiment is configured as follows in order to improve diagnostic accuracy. The diagnosis supporting device includes an imaging unit that images a subject, an eye gaze detector that detects an eye gaze direction of the subject from an image captured by the imaging unit, a gaze point detector that detects a gaze point of the subject in a display area of a display based on the eye gaze direction; and an output controller that causes the display area to display a diagnostic image composed by superposing a pattern image onto a natural image.
