Abstract

　最適な収音環境をユーザにより分かりやすく提示することができる収音装置を実現する。放収音機能装置１は所定位置に設置され、ＵＳＢケーブル３００によりＰＣ２に接続されている。ユーザ９００が放収音機能装置１を操作して放収音アプリケーションを起動すると、放収音機能装置１は副筐体１１，１２の回動量を検出してＰＣ２へ与える。ＰＣ２は、取得した回動量に基づいて主筐体１０と副筐体１１，１２との位置関係を算出し、同等の位置関係を有する使用態様を判定する。ＰＣ２は、同等の使用態様が有ると判定すると、当該同等の使用態様に基づく、放収音機能装置１の形状、話者数、話者位置、収音範囲を含むインジケータ表示を行う。ユーザ９００は、このインジケータ表示を見ることで、最適な話者数や話者位置を確認する。
