Abstract

Gestural communication is part of non-verbal communication, but it is also a method that deaf people use to communicate with others through sign languages. In this paper, we present the research to improve communication in virtual characters no matter if it is spoken or signed using non-verbal communication. A brief study of hand gestures has been made to obtain some rules to improve natural behaviour in virtual characters. These rules, like the use of beats, are applied in an animation engine that emulates the behaviour of real people. The behaviour of the virtual character can also be modified by other channels such as user's input, so the character's attitude has to be adapted. This paper describes the architecture and main modules of the prototype designed to achieve natural behaviour in virtual characters and present the validation results obtained during the first phase of the development.
