Force-distribution-based evaluation of product design suitable for dynamically dexterous human hand manipulation

This paper presents development of an evaluation system for easiness of manipulation of product shapes to design better product shapes. In developing the evaluation system, we concentrate mainly on manipulation which involves handling state such that even when the product is rotating it remains near the hand. The evaluation system consists of a glove type hand posture measuring instrument and physics simulation software environment in which a hand model moves in accordance with the pose of the hand wearing the glove. Observation of hand manipulation is also performed with a high-speed camera to analyze the motion and improve the evaluation system.
