Abstract
One of the major challenges that the human computer interface (HCI) faces nowadays is that of identifying a subject’s state, in a real world environment, characterized mainly by its being: open-recorded, event-elicited, and internal emotional state-driven (Picard, Vyzas, & Healey , 2001). The main requirement for such system regards the noninvasive character of their working principle. Subsequently, in order to improve communication in HCI systems or to asses the human state, the analysis of the body language could be a solution. Thus, a “sensitive computer” could use the body movements and the positions of the body in order to assess the state of a person (e.g., confusion, illness, nervousness, lack of attention, motor fatigue, agitation, etc.).
