Why Do I Feel Like This?

Abstract

One of the milestones in creation of virtual characters is the achievement of believability, which can be done through the representation of emotions using behaviours, voice, or facial expressions. To know which emotions to elicit in a variety of situations it is necessary to have a framework for reasoning, which is why context representation is important when creating synthetic emotions. It provides a description of what is occurring around the character, eliciting different emotions in the same situation or the same emotions in different situations. The novelty of this work is the representation of context, not only as events in the world, but also as the internal characteristics of the character, which when related with the events, give believable emotional responses.
