Using Periodic Systems to Model Hand-Haptic Interface Coupling

The analysis of hand-haptic interface coupling as a whole system is an important question for the development of high quality haptic devices and their use in dynamical tasks where the haptic modality plays an important role. In this paper, we propose a periodic system, the Van der Pol equation, as a first approach for modeling hand-haptic interface coupling. In particular, we are interested in periodical gestures or tasks and the interaction models able to generate them. We analyze this system and we identify its parameters from the data position acquired during simulation. In this paper we present some preliminary results.The identification of this parameters should lead as to improve haptic systems performances.
