Characterization of the cinematic by the means of dynamical models

This paper describes the characterization of the cinematic of a rotation movement of the forearm in the horizontal plane. The recorded position is modelized as a linear differential equation relating the actual position to the target position. This approach is to our knowledge original. The parameters of this equation are then identified using an identification method which is described. Our first results show that this approach may be an alternative to that, more classical where characterization is obtained by the analysis of a few characteristic variables of the recorded trajectory.
