Grasping Animation Based on Object Features

Abstract

Hand animation requires a lot of time and cost to create, because hand motion is very delicate and complex. Especially for grasping motion, it differs depending on the grasping object. We focus on the fact that hand motion for grasping objects depends on geometry features of the object including size and sharp. In other words, sharps of those objects give importamt clues to understand how hand motions manipulate yhem. The relative directions to reach the object, for example, may specify how a human approaches and grasps it. Based on this idea, we propose a method for hand animation with interference to the object. Experimental results showed that this technique has a potential for easily designing, computer generated hand animations.
