Emotion Simulation for a Virtual Human: Implementing the "As-If" Body-Loop in a Cognitive Architecture
by Mr

Abstract: In recent years, the integration of emotion-driven behaviors became prominent in the field of virtual humans. The virtual human under development at the , called Max, is a testbed for studying human-like behavior in natural face-to-face interactions. To endow its cognitive architecture with simulated emotions, we follow Damasio's distinction of "primary" and "secondary" emotions. Primary ones are elicited as an immediate reaction to a stimulus that might originate from internal bodily processes; secondary ones (e.g. relief, hope) arise from cognitively higher processes of conscious appraisal. I will first introduce our agent's cognitive architecture and its employment in two different interaction scenarios. Then I will present the psychological background for emotion simulation, distinguishing structural and dimensional emotion theories. Finally I will outline the implementation of an "as-if" body-loop, based on a distinction between physis and cognition in our architecture to simulate and express primary and secondary emotions.

Speaker: Mr Becker received his M.S. degree from the , and is currently a Ph.D. student and research assistant in its Artificial Intelligence Group. Pre-Doctoral Fellow of the (JSPS), he stayed at the during 3 month in 2005. His current research focuses on the simulation of complex emotions for conversational artifacts.
