An improved articulated model of the human hand

摘要

We present an improved anatomically based approach to modeling the human hand for use in the animation of the American Sign Language. The joint rotations in the model Are based on the bone and muscle configu- Rations of the hand, and a forward kinematic Solution is used to position the hand. In par- Ticular, we investigate the rotations of the Base joint of the thumb. This joint is a sad- Dle joint with nontrivial rotational axes and Centers, and must be treated with care in such A model.
