Outline of Final Research Achievements

This study investigated whether OKN corresponding to the attended motion occurred to estimate the attended area. The results showed it possible to predict the directed area of attention and attentional shift based on OKN direction and pupillary response when areas of motion have different directions in the visual field. Furthermore, these results showde this method can be used to estimate individual differences in the degree of autism spectrum disorder.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果から，OKNの制御機構と瞳孔の調整機構が密接に関連することが示唆される．本研究の成果は，個人差に適応した実環境における注意位置・注意シフト推定システムの向上に大きく貢献し，車両の事故防止や人とマシンの円滑なコミュニケーションの実現に寄与するだけでなく，自閉症スペクトラム障害など，個人の心理的特性を推定するバイオマーカーの開発にも貢献が期待できる．
