Abstract

Since the beginnings of character animation, anticipationhas been an effective part of the repertoire of tricks used to create believable animated characters. However, anticipation has had but a secondary role in the creation of synthetic virtual life forms. In this paper, we describe how a simple anticipatory mechanism that generates an affective signal resulting from the mismatch between sensed and predicted values -- the emotivector-- can help in the creation of consistent believable behaviour for intelligent virtual characters.
