To provide a consciousness determination device and a consciousness determination method that determine a consciousness state of a driver regarding an arbitrary direction.SOLUTION: A processing unit of a consciousness determination device generates a time series of detection elements which are regarded as a state indicating whether a visual line of a driver driving a vehicle is directed to any of a plurality of preset sight areas and an eye opening and closing state of the driver (S10-S40). Detection data is extracted with the use of a time window from the time series of the detection elements (S50). States of visual lines of the driver are aggregated for each of the sight areas with the use of the detection data (S60). A consciousness state of the driver is determined for events associated with the plurality of sight areas or associated with each of the plurality of sight areas, from an aggregated result in an aggregation unit (S70).SELECTED DRAWING: Figure 2
【課題】任意の方向についてのドライバの意識状態を判定する意識判定装置及び意識判定方法を提供する。【解決手段】意識判定装置の処理部は、車両を運転するドライバの視線が、予め設定された複数の視領域のいずれに向いているかを示す状態、及びドライバの目の開閉状態を検出要素として、検出要素の時系列を生成する(S10〜S40)。検出要素の時系列から、時間窓を用いて検出用データを抽出する(S50)。検出用データを用い、視領域毎に、ドライバの視線の状態を集計する(S60)。集計部での集計結果から複数の視領域又は複数の視領域のそれぞれに関連づけられる事象に対するドライバの意識状態を判定する(S70)。【選択図】図2
