PROBLEM TO BE SOLVED: To provide an operator state determination device and an operator state determination method capable of easily determining an operator state of an object person who operates an appliance.SOLUTION: An operator state determination device (10, 110, 400, 400A, 400B) comprises: a face change information acquisition part (20, 120, 415, 442); a face change information decomposition part (30, 130, 443); and an operator state determination part (200, 445). The face change information acquisition part (20, 120, 415, 442) acquires face change information which indicates time series data of face data of the object person. The face change information decomposition part (30, 130, 443) decomposes the face change information into plural components 1, 2, 3 by singular value decomposition, principal component analysis or independent component analysis. The operator state determination part (200, 445) determines the operator state of the object person on the basis of a determination component extracted from the plural components 1, 2, 3.SELECTED DRAWING: Figure 19

    【課題】機器を運転する対象者の運転者状態を容易に判定し得る運転者状態判定装置及び運転者状態判定方法を提供する。【解決手段】運転者状態判定装置(10,110,400,400A,400B)は、顔面変化情報取得部(20,120,415,442)と、顔面変化情報分解部(30,130,443)と、運転者状態判定部(200,445)と、を備える。顔面変化情報取得部(20,120,415,442)は、対象者の顔面データの時系列変化を示す顔面変化情報を取得する。顔面変化情報分解部(30,130,443)は、顔面変化情報を、特異値分解、主成分分析或いは独立成分分析により複数の成分1,2,3,・・・に分解する。運転者状態判定部(200,445)は、複数の成分1,2,3,・・・から抽出された「判定用成分」に基づいて、対象者の運転者状態を判定する。【選択図】図19
