PROBLEM TO BE SOLVED: To estimate a state of a monitoring target person accurately, in a state estimation device estimating a state of the monitoring target person on the basis of eye movement of the monitoring target person.SOLUTION: In a state estimation device according to one aspect of the invention, frequency acquisition means acquires a normal saccade frequency representing an occurrence frequency of a saccade in a monitoring target person and a micro saccade frequency representing an occurrence frequency of a micro saccade in the monitoring target person(S15, S20). Then, state estimation means estimates a state of the monitoring target person on the basis of the normal saccade frequency and the micro saccade frequency (S40).SELECTED DRAWING: Figure 3
【課題】監視対象者の眼球運動に基づいて監視対象者の状態を推定する状態推定装置において、より精度よく監視対象者の状態を推定できるようにする。【解決手段】本発明の一側面の状態推定装置において、頻度取得手段は、監視対象者のサッカードの発生頻度を表す通常サッカード頻度、および監視対象者のマイクロサッカードの発生頻度を表すマイクロサッカード頻度を取得する(S15,S20)。そして、状態推定手段は、通常サッカードの頻度およびマイクロサッカードの頻度に基づいて、監視対象者の状態を推定する(S40)。【選択図】図3
