A fundamental study was tried on the development of three dimensional CAD manikin for the visualizations of shape, motion and sensation of the hand, and for the estimation of physical and mental stresses, in virtual manual handling with products designed on the computer display. In this study, basic data related with the hand characteristics (anthropometry, morphometry, grip force, motion, sensation and cognition) were wrapped up for the development of CAD manikin.1) Detail anthropometric data(length, depth, width and proportion, etc.) were obtained of Japanese adult male and female hands. And, the regression formula were conducted in order to obtain the morphometric data of manikin hand from ISO/JIS fundamental anthropometric data base.2) Power grip force and its vector elements, motion and joint angles of hand in Japanese adults were analyzed in the gripping of cylindrical form with a three dimensional motion analysis system. These data will be applied for the estimations of physical load and efficiency in manual handling.3) The relationships between visual sensations and tactile ones of object form were investigated. The correlation and differentiation between these two modalities were conducted, and these results will be applied for the estimation and visualization of tactile sensation on the CAD manikin.4) The coordinate system of cognitive space based on the hand was investigated. And this coordinate system was found our to be variable in different positions and directions of hand.5) The construction of basic virtual model of joint was tried on the computer display. And the possibility and trend in the CAD manikin of the hand were discussed.

对三维CAD人体模型的开发进行了基础性的研究，以实现手的形状、运动和感觉的可视化，并用于估计在计算机显示器上设计的产品的虚拟手动操作中的身体和精神压力。本研究将与手部特征相关的基础数据（人体测量学、形态测量学、握力、运动、感觉和认知）进行汇总，用于CAD人体模型的开发。1)获得日本成年男性和女性手的详细人体测量数据（长、深、宽、比例等）。并通过回归公式从ISO/JIS基础人体测量数据库中获得假人手的形态测量数据。2)利用三维运动分析系统，分析了日本成人在圆柱形抓握时的握力及其矢量元、手部运动和关节角。这些数据将用于估计物理负载和人工处理效率。3)研究了物体形态的视觉感觉与触觉感觉之间的关系。对这两种模态进行了关联和区分，这些结果将用于CAD人体触觉的估计和可视化。4)研究了基于手的认知空间坐标系统。这个坐标系在手的不同位置和方向上是可变的。5)在计算机显示器上尝试了关节基本虚拟模型的构建。讨论了手的CAD模型应用的可能性和发展趋势。
