Title:
REFLECTIVITY DETERMINATION DEVICE, REFLECTIVITY DETERMINATION METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2020000266
Kind Code:
A
Abstract:
To provide a technique for determining reflectivity of eye movements.SOLUTION: A reflectivity determination device includes a feature amount extraction part for extracting the feature amount of saccades that occur in a subject's pupil movement in a task of moving eyes to follow a visual or auditory signal (first feature amount) and the feature amount of saccades that occur in the subject's pupil movement in a task of moving eyes in the direction opposite to a visual or auditory signal (second feature amount), and a determination part for generating a determination result to show whether the subject's eye movement occurs reflectively, depending on the degree of difference between the first feature amount and the second feature amount. The determination part generates a determination result which shows that the subject's eye movement occurs reflectively when the degree of difference is large, and generates a determination result which shows that the subject's eye movement does not occur reflectively in other cases.SELECTED DRAWING: Figure 4
