 note = {従来の多くの共有ホワイトボードシステムでは，多様なメディアで表わされた議論の対象を共有する機能とユーザの振舞い(arene)，議論の焦点，注釈メッセージ(notati)を共有する機能が別々に提供され，それらの間の情報交換やデータ変換に複数ステップの操作が必要であった．これに起因するコミュニケーションの即時性と連続性の損失に対して，我々は単純なメカニズムで実現した透明なウインドウを共有アプリケーションのウインドウに重畳させ，AwarenessとAnnotationのグループインタフェースを整理することで，議論対象・焦点・注釈メッセージを統合的に共有するシステムCOGENT　SHAREを設計・試作した．本稿では，COGENT　SHAREの機能設計と特徴，透明ウインドウの簡単なインプリメント法およびAnnotationツールとしての描画インタフェースなどについて述べる．, It is important for shared whiteboard systems to support the functions to share the following factors: the objects of arguments, the behavior of users (awareness) the focuses of the arguments and the annotation messages (annotation). In traditional systems, however, these functions are usually supported by separately and a number of command steps are necessary for the information exchanging or data converting; therefore, instancies and continuities of the communication have been disturbed. In order to eliminate interruptions in consideration originated by these loss of instancies and continuities and to support smooth and effective collaboration, COGENTSHARE has covered a shared application window (as a argument object represented by multimedia) with shared transparency windows. Consequently COGENTSHARE provides the functions to integrate and share the distributed argument object, focuses and annotation messages. In this paper, we describe the COGENT SHARE design and its features, a simple method of implementing transparent windows and the drawing interfaces as a annotation tool.},
