Combining physically-based simulation and animation obtained by motion-captured data is a new technique used to adapt the motions captured in studio to the application's needs. In this paper, the focus is on adapting motion-captured sequences to flexible reactions of a virtual human to perturbations, without losing motion realism. The proposed technique follows some of the ideas presented in the literature, but uses a new way of computing feedforward controllers through an auxiliary dynamic simulation. This new computation is simple, general and efficient, and allows the computation of the feedforward controllers in run time. These claims are demonstrated through experiments described in the example section and in the accompanying videos.
