デジタルハンドとプロダクトモデルとの統合によるエルゴノミック評価システムの開発（第1報）: 製品の把持安定性仮想評価機能

摘要

The purpose of this research is to develop a system that can evaluate stability and ease of a person grasping products such as digital cameras without real subjects and physical mockups. In the system, we integrate 3D digital hand models with the 3D CAD models of the product to realize the virtual ergonomic assessment. The system features are the following; i) Geometrically accurate 3D digital hand models with rich Japanese size varieties are used for the assessment, ii) A semi-automatic grasp planning function is installed to efficiently find appropriate grasp posture for the exterior housings geometries of appliances, and iii) "Force-closure" and the "grasp quality" indices can quantitatively evaluate grasp stability for the product.%近年，デジタルカメラ，マウス，電動工具，ボトル容器など，rn手での把持・操作を必要とする製品の開発において，エルゴノrnミック設計を行うことで製品の付加価値や市場競争力を高めるrnことへの関心が高まり，またその認証制度も発足している．
