To provide an attention alert device capable of performing estimation according to details of an inattentive state of a user and performing a notification according to the details of the inattentive state.SOLUTION: An attention alert device comprises: a viewpoint position measurement unit (measurement means) for measuring a position of an attention point of a driver (a user); a saccade measurement unit (measurement means) for measuring a saccade distance that is caused by the saccade of an eyeball and a saccade interval; a pupil diameter measurement unit (measurement means) that measures a pupil diameter; an inattentive state estimation unit (estimation means) that estimates whether the driver is in an inattentive state and the details of the inattentiveness state on the basis of measurement results of the view point position measurement unit, the saccade measurement unit and the pupil diameter measurement unit; and a notification control unit (notification means) that provides a notification according to the details of the estimated inattentive state to the driver when the inattentive state estimation unit estimates that the operator is in the inattentive state.SELECTED DRAWING: Figure 4

    【課題】利用者の注意散漫状態の内容に応じた推定を行い、注意散漫状態の内容に応じた報知を行うことができる注意喚起を提供する。【解決手段】注意喚起装置は、運転者(利用者)の注視点の位置を計測する視点位置計測部(計測手段)と、眼球のサッカードによって発生したサッカード距離とサッカード間隔とを計測するサッカード計測部(計測手段)と、瞳孔径を計測する瞳孔径計測部(計測手段)と、視点位置計測部とサッカード計測部と瞳孔径計測部との計測結果に基づいて、運転者が注意散漫状態であるか否かと、注意散漫状態の内容とを推定する注意散漫状態推定部(推定手段)と、注意散漫状態推定部が、運転者が注意散漫状態であると推定した場合に、当該運転者に対して、推定された注意散漫状態の内容に応じた報知を行う報知制御部(報知手段)と、を備える。【選択図】図4
