Abstract / Description of output

Developing an embodied conversational agent able to exhibit a humanlike behavior while communicating with other virtual or human agents requires enriching the dialogue of the agent with non-verbal information. Our agent, Greta, is defined as two components: a Mind and a Body. Her mind reflects her personality, her social intelligence, as well as her emotional reaction to events occurring in the environment. Her body corresponds to her physical appearance able to display expressive behaviors. We designed a Mind—Body interface that takes as input a specification of a discourse plan in an XML language (DPML) and enriches this plan with the communicative meanings that have to be attached to it, by producing an input to the Body in a new XML language (APML). Moreover we have developed a language to describe facial expressions. It combines basic facial expressions with operators to create complex facial expressions. The purpose of this chapter is to describe these languages and to illustrate our approach to the generation of behavior of an agent able to act consistently with her goals and with the context of the interaction.
