EE-FAS ArchitectureEE-FAS Architecture Modular Customisable DER Message passing mechanism Implementation of all LoCs:
– LoC1: 3D Mesh– LoC2: Abstract Muscles– LoC3: Facial Signals– LoC4: Emotions and
Communicative functions
Customisable transformations from one LoC to another
Loose relation between LoCs

Conclusion (1)Conclusion (1)
We developed a Dynamic Emotion Representation (DER) model that enables users– To create their own Emotion Representation based on
different emotion theories.– To represent any interacting variable, such as drives
We integrated an instance of the DER model within the EE-FAS

Conclusion (2)Conclusion (2)
Developed an Emotionally Expressive Facial Animation System (EE-FAS), which:– Enables non-specialist users to create facial animations– Is customisable through XML dictionaries
EE-FAS extends the number of facial expressions that a such system can produce by displaying:– Emotional expressions– Multiple facial signals for each communicative function– Fake or genuine facial expressions
