Imparting Individuality to Virtual Humans

Abstract: In this paper, we present an integrated method of linking personality and emotion with the response generation and expression synthesis of Virtual Humans. The characters are powered by a dialogue system that consists of a large set of basic interactions between user and computer. These interactions are encoded in finite state machines. Transitions are linked with conditions and actions that can be connected with external modules. One of these modules is a personality module. In this way, responses of the virtual human depend not only on input given by a user, but also on its personality and emotional state. The dialogue system is connected to a 3D face that performs the speech and facial animation, together with facial expressions that reflect the personality specification.
