investigating the relation between robot bodily expressions and their impression on the user
During an interaction process, people usually adapt their behavior according to the interpretation of their partner's bodily expressions. It is not known how much similar expressions performed by robots affect a human observer. This paper explores this issue. The study shows a correlation between the nature of the bodily expressions, through the result of questionnaires, and the effect on brain activity. It has been demonstrated that unpleasant bodily expressions of the robot elicit unpleasant impressions and vice versa. This was observed through brain activity in a specific area when the expression is pleasant, and in another area when it is unpleasant.
