ヒューマンインタフェースの立場から見た機械へのより良い情報入力の方法として,人間の自然な振る舞いを機械が認識し,情報入力を行うことが考えられる.この1つの方法として,手形状を用いて情報入力を行うことが考えられるが,この場合非接触による手法が望ましい.本稿では画像処理技術を用いて非接触により手形状認識する方法について述べる.本手法では2台のカメラを用い手の特徴点を3次元的に抽出しモデルを用いたマッチングにより形状認識を行う.これにより入力姿勢の制限を少なくし,認識精度の向上が計れると思われる.

This study examines the concepts of formal organizations, social systems, and personal systems defined by C. I. Barnard. In 1958, Barnard described that every formal organization was a social system. This description conflicts with the definition he expressed in 1938, when he defined organizations as subsidiary systems within cooperative systems that include physical, personal, and social systems. In this paper, an effort is made to explain and resolve these contradictions. Unlike previous study which focused on Barnard's personal situation, the study examines the theoretical reasons behind his personal situation at the time. By proposing an inclusive, stratiform concept of social systems, this study explains the differences among the following three concepts: formal organizations, social systems, and personal systems. This paper also points out the significance of the social systems presented by Barnard in 1938. Results of this study arbitrate between the concepts presented by Barnard in 1938 and 1958 concerning formal organizations. Furthermore, a linkage between ideas maintained by Barnard and Luhmann is proposed.
