features of the human behavior are mapped to the agent behaviors.
Consequently, the agent does not repeat the human movements but its
individual behavior is modified to fit the user’s expressive behavior
profile. The system was only partially implemented and it was not
working in a real-time. Thus, natural human-machine interaction was
not possible. Instead, the gesture expressivity parameters detected
with the gesture analysis module were used to control manually
a virtual agent that implements Hartmann’s model of expressive
behavior (Hartmann et al., 2005; see also Sections 2.2 and 3). Caridaki
