| Research Abstract |
The purpose of the research is to build a virtual ergonomic assessment system for handheld products such as digital cameras based on the Digital Hand. The Digital Hand is a model which can simulate the 3D precise outer skin geometry and finger kinematic structure of human hands. Ease-of-grasp and ease-of fingered operation can be quantitatively evaluated in the system. The following functions were developed ; (1) Constructing Digital Hand models based on MRI measurement of human hands, (2) Optimization-based grasp posture synthesis, (3) Quantitative estimation of ease-of-grasp based on muscle-skeletal model, (4) Quantitative estimation of ease-of fingered operation, and (5) Efficient contact deformation simulation between hand and product. Moreover, the developed software was applied to evaluating the product shape in real design environments of manufactures.
