In this technical report, we shall put forward a novel strategy to evaluate the emotion information, quantifying the complicated spatio-temporal dynamics of the human brains in terms of such universal characteristics of the physiological signals as fractal dimensions, which has been observed in EEG we we11 as the near infra-red spectroscopy(NIRS). In several practical applications, we have succeeded to evaluate the sensibility, i.e. emotion information by means of fractal analyses with an appropriate accuracy as well as a relatively high time-resolution beyond the conventional approaches based on the power spectral analyses with band-separated signals, i.e. emotion spectral analysis method (ESAM).%本報告では．フラクタル理論に基づき脳波や近赤外分光計測に観られる複雑性の普遍的な特徴量であるフラクタル次元を求め．ヒト脳の時空間ダイナミクスを定量化し．感性情報を計測するための新規手法を提案する．具体的な問題に対して．従来のスペクトル解析に基づく手法では困難であった，比較的高い時間分解能と高い計測精度を実現することに成功した．
