Abstract
One of the challenges in the simulation of human motion, either applied to humanoid robots or avatars in virtual environments, is to design a kinematics structure and a set of joint trajectories that move a robot or avatar in a human-like manner.
In this paper, a technique is introduced to create accurate humanlike motion with a simplified topology as a reference. Using an
optical motion capture system, a finite number of key poses are captured from different subjects performing full body articulated movements. Motion is modeled using the Clifford algebra of dual
quaternions and dimensional synthesis techniques are applied to generate the kinematic skeleton of a 3D avatar or robot. The synthesized kinematic skeleton provides location of joints and dimensions of the links forming the limbs, as well as the joint
trajectories. Five serial chains constitute our approximation to the human skeleton. Revolute, universal and spherical joints are
employed, although other topologies can be used in a similar fashion. Several real datasets are evaluated and results demonstrate that good accuracy can be obtained at interactive rates
using the presented methodology. The results show that using simple serial chains in combination with dimensional synthesis
suffices to generate the mechanical structure and trajectories of
a humanoid robot or 3D avatar mimicking human motion.
