MPEG-4 Facial Expression Synthesis based on Appraisal Theory
3rd IFIP conference in Artificial Intelligence Applications and Innovations, AIAI 2006
ABSTRACT
MPEG-4 facial animation parameters are used in order to evaluate theoretical predictions for intermediate expressions of a given emotion episode, based on SchererĘs appraisal theory. MPEG-4 FAPs and action units are combined in modelling the effects of appraisal checks on facial expressions and temporal evolution issues of facial expressions are investigated. The results of the synthesis process can then be applied to Embodied Conversational Agents (ECAs), rendering their interaction with humans, or other ECAs, more affective.
