An Empirical Study on Real-time Generation of Facial Expressions in Avatar Communications

지적 아바타 통신을 위한 얼굴 표정의 실시간 생성에 관한 검토

As a means of overcoming the linguistic barrier in the Internet cyberspace, recently a couple of studies on intelligent avatar communications between avatars of different languages such as Japanese-Korean have been performed. In this paper we measure the generation time of facial expressions on different avatar models in order to consider avatar models to be available in real-time system. We also provide a short overview about DTD (Document Type Definition) to deliver the facial and gesture animation parameters between avatars as an XML data.
