To improve estimation accuracy for estimating attention allocation to a main operation of an operator based on an event related potential.SOLUTION: In an attention state estimation method, a behavior of an operator is monitored (S2); a main operation or a sub-operation other than the main operation of the operator is estimated based on the behavior of the operator (S3); a brain activity of the operator is measured (S1); a first event related potential and a second event related potential which has a correlation with the first event related potential and is less affected by an event occurrence frequency than the first event related potential are extracted based on the estimated operations of the operator and the measured brain activity (S4, S5); an attention level of the operator to the main operation is estimated from the first event related potential; an attention level of the operator to the sub-operation is estimated from the second event related potential; and an attention allocation to the main operation of the operator is estimated based on the estimated attention level to the main operation and the estimated attention level to the sub-operation (S6 to S12).SELECTED DRAWING: Figure 5

    【課題】事象関連電位に基づいてオペレータの主操作への注意配分を推定する際の推定精度を向上する。【解決手段】注意状態推定方法では、オペレータの挙動を監視し(S2)、オペレータの挙動に基づいて、オペレータの主操作又は主操作以外の副操作を推定し(S3)、オペレータの脳活動を計測し(S1)、推定したオペレータの操作と測定した脳活動とに基づいて、第1事象関連電位と、第1事象関連電位と相関関係を有し且つ第1事象関連電位よりも事象発生頻度の影響を受けにくい第2事象関連電位と、を抽出し(S4、S5)、第1事象関連電位からオペレータの主操作への注意度を推定し、第2事象関連電位からオペレータの副操作への注意度を推定し、推定した主操作への注意度と推定した副操作への注意度とに基づいて、オペレータの主操作への注意配分を推定する(S6~S12)。【選択図】図5
