 note = {本稿では，オープンスペース内に存在する複数の人や物の間で偶発的に生じる対面インタラクションの参与者グループを，身体配置に基づいて認識するための手法について議論する．このとき参与者グループが取り囲む空間に着目し，これを画像の領域抽出等に用いられるレベルセット法を用いて，空間内の人や物の位置・向きを基に人・物に取り囲まれた空間を対象空間中から抽出し，その中に含まれる人物を同一グループとして間接的に認識するというアプローチを提案する．, This article discusses how to recognize groups of humans and objects interacting with each other in an open space based on their formations. Since humans and objects included in the same group of interaction often take some distinguishing formation, we propose to extract spatial regions occupied by groups of humans and objects taking that formation from their positions and orientations in a real environment by the level set method, which is often used for region extraction in image processing, so that the humans and objects included in the same region are recognized to be interacting with each other as the same group.},
