| Abstract | The purpose of this research is to develop a simulator that can evaluate stability and ease of a person grasping handheld information appliances such as digital cameras without real subjects and physical mockups. In the simulator, we integrate 3D digital hand models with the 3D CAD models of the appliance to realize the virtual grasping assessment. The simulator features are the following: 1. Geometrically accurate 3D digital hand models with rich Japanese size varieties are used for the assessment, 2. A semi-automatic grasp planning function is installed to efficiently find appropriate grasp posture for the exterior housings geometries of appliances, 3. "Force-closure " and the "grasp quality " indices to quantitatively evaluate grasp stability for the product, and 4. Ease of grasping can be qualitatively evaluated based on "comfort database " constructed from the PCA for measurements of finger joint angles of a real subject. 1 |
