Abstract
Within this work, we make a first attempt towards improving human motion capture by combining
motion capturing measurements and optimal control simulations of a human steering motion.
We start with measurements obtained from a stationary optical system, a widespread capturing
technology in biomechanics and movement science, under laboratory conditions. From an optimal
control point of view, the goal is to increase the realism of simulated human motion through
measurements. From a motion capturing point of view, the goal is to compensate for measurement
sparsity, errors or lacks through meaningful assumptions based on biomechanical simulation. Our
preliminary results show that a fusion of physical laws, biomechanical simulation and real data
within an optimal control simulation framework indeed have the potential to improve motion capture
and synthesis with respect to some of their inherent problems.
