PROBLEM TO BE SOLVED: To provide a brain wave estimating device which estimates a neck myoelectric potential without adhering an electrode to a neck, and removes the estimated neck myoelectric potential from the electroencephalographic data as a noise component, and to provide a brain wave estimation method and a program.SOLUTION: The brain wave estimating device 100 includes: an engine operation determination section 110 a brain wave measurement section 120 for measuring a brain wave a face direction measurement section 130 for measuring an angle of the face direction of a driver a neck myoelectric potential data accumulation section 140 for associating the measured face direction angle and the electroencephalographic data measured by the brain wave measurement section 120 to accumulate as a neck myoelectric potential data a neck myoelectric potential estimation section 150 for estimating the neck myoelectric potential according to the measured face direction angle, referring to the neck myoelectric potential data accumulated in the neck myoelectric potential accumulation section 140 and a brain wave signal processing section 160 for removing the neck myoelectric potential from the measured electroencephalographic data as the noise component. Thus, the neck myoelectric potential component that is directly influenced by the driving action while driving is removed from the electroencephalographic data without directly measuring the neck myoelectric potential.COPYRIGHT: (C)2012,JPO&INPIT【課題】頸部へ電極を付着することなく頸部筋電位を推定して、推定した頸部筋電位をノイズ成分として脳波データから除去する脳波推定装置、脳波推定方法及びプログラムを提供すること。【解決手段】脳波推定装置100は、エンジン動作判定部110と、脳波を計測する脳波計測部120と、運転者の顔向き角度を計測する顔向き計測部130と、計測した顔向き角度と脳波計測部120で計測した脳波データとを対応付けて頸部筋電位データとして蓄積する頸部筋電位蓄積部140と、頸部筋電位蓄積部140に蓄積された頸部筋電位データを参照し、計測した顔向き角度に応じて頸部筋電位を推定する頸部筋電位推定部150と、計測した脳波データから前記頸部筋電位をノイズ成分として除去する脳波信号処理部160とを備え、頸部筋電位を直接計測することなく、運転中の運転行動が直接影響する頸部筋電位成分を脳波データから除去する。【選択図】図2
