PROBLEM TO BE SOLVED: To provide an inattention determination system and method capable of properly determining a user's inattentive state.SOLUTION: An inattention determination system 1 includes a line-of-sight direction detection unit 15d that detects a user's line-of-sight direction, an inattention determination unit 15f that determines based on a result of comparison of a time, during which the user's line-of-sight direction is an inattentive direction other than a direction in which the user should look at during driving, with a threshold whether the user is in an inattentive state, and a threshold change unit 15g that changes the threshold according to at least one of the travel state of a vehicle and the user's line-of-sight direction that is the inattentive direction.SELECTED DRAWING: Figure 1
【課題】ユーザの脇見状態を適切に判定することができる脇見判定装置及び方法を提供する。【解決手段】脇見判定装置1は、ユーザの視線方向を検知する視線方向検知部15dと、ユーザが脇見状態であるか否かを、ユーザの視線方向が運転中に見るべき方向以外の脇見方向である時間と閾値との比較結果に基づいて判定する判定する脇見判定部15fと、車両の走行状態及びユーザの前記脇見方向における視線方向の少なくとも一方に応じて閾値を変更する閾値変更部15gと、を有する。【選択図】図1
