The purpose of this research is to develop a virtual ergonomic assessment system that evaluates grasp stability and ease of grasping of products such as digital cameras without real subjects and physical mockups by integrating 3D digital hand models with the 3D CAD models of the products. In this paper, we propose “ease of grasping” as a new index for the assessment. This index is calculated from the “EOG-map”, in which example grasp postures of real subjects are plotted as principal component scores in low dimensional space. We also propose an optimization-based correction method for an inappropriate finger posture by using the EOG-map.
