Abstract
First results on characterizing the human action as a controller are presented. The corresponding model of the human behavior as a control block is obtained by means of experimentation, and statistically validated. The identified human control mode corresponds to a nonlinear PID model. Using the methodology presented in this paper, it is possible to forecast parameter magnitude and therefore to implement a predictive system of the human behavior. The experimental platform consists of a 3D virtual space and a PHANToM haptic interface. A dual AMD Athlon-MP processor computer is used as real-time processing unit. RTLinux 3.1 operating system and PHANToM driver written by Zdenek Kabelac are used in order to achieve timing restrictions.
