It means that matchings ANS1 – ANS3 were in general confirmed by our subjects. On the other hand, many persons provided answers different from our expectations. In particular, the percentage of the participants that answered all questions differently to our expectations is relatively high. 7 Conclusion In this paper we described an architecture that uses facial expressions in order to express interpersonal relations of an ECA. The agent is able to mask, hide or even simulate the expression of its emotions taking into account the social context.

These types of occlusions are potentially more damaging since they result in whole features of relevance to judging facial expression being obscured. A. Paiva, R. W. ): ACII 2007, LNCS 4738, pp. 36–47, 2007. c Springer-Verlag Berlin Heidelberg 2007 Reconstruction and Recognition of Occluded Facial Expressions 2 37 Background A facial expression can be represented as a set of feature points retrieved from points across that face, for example, eye, brows, mouth. Ways in which principal component analysis (PCA) can be employed with this data is to train a PCA model with multiple sets of these points, obtained when a person is making multiple expressions or from a set of people making different expressions.

These cases were chosen in order to emphasise the differences between different types of interpersonal relations. The first situation illustrates relations between two persons that are close to each other. The second situation is a typical example of a relation in which the social distance is high (Greta interacts with a stranger). Finally, in the last case our intention was to model a situation of submission. The distance is high and the opponent has a power over the displayer. e. the values of power and distance do not change.
