アクションユニット・モジュール(Action Unit Module)
FaceReaderは、一般的に使用されている20種類のアクションユニット(頬の浮き上がり、鼻のしわ、眉の上げ下げ、唇の締めなど)を自動的に分析します。 行動単位は、個々の筋肉または筋肉群の動きです。アクションがアクティブになると、その強度がA、B、C、D、Eの5つのカテゴリに表示されます。出力は、さまざまな色でこのスケールで提示され、Excel、The Observer XT、または選択した別のプログラムで、更なる分析のためのエクスポートができます。 FaceReader APIを使用して、詳細ログを数値としてエクスポートしたり、リアルタイムのエクスポートができ、アクションユニットによって駆動される適応型アプリケーションを作成することができます。 このモジュールは、特に大量のビデオ録画を分析する場合、貴重な情報を最小限の時間で提供します。
