The Internet today already uses a lot of text, pictures, videos, animations, etc. to attract the user attention. Considerable advancement in this direction can be achieved by improving the interactivity with the user. In this article, we expose different methods for designing facial models and to make them interactive based on MPEG-4 facial animation parameters. We explain the integration of the web version of our MPEG-4 Facial Animation system in an applet towards making the web pages not only attractive but also interactive.
Facial modeling and animation is an important research topic in computer graphics. During last twenty years, a lot of research work has been done on this topic. It still remains to be a challenging task to create and animate very realistic faces. The impact of the previous and ongoing research has been felt in many applications, like games, web based 3D animations, 3D animation movies, etc. Different approaches have been taken such as pre-calculating animation with very realistic results used for animated film productions and real time animation for interactive applications. Correspondingly, the animation techniques vary from key- frame animations where experienced animator sets each frame with artistic precision to algorithmic parameterized mesh deformation. The current developments are towards having real time facial animation on the web, maintaining quality and beauty of animation.
With the recent development of Internet services, new applications for virtual human technologies can be identified. Talking virtual characters can be useful when integrated into web sites to provide new services as navigation aid, salespersons, hosts, presenter, etc. In this article, we explain a technique for constructing interactive talking head based on MPEG-4 facial animation standard for a web- based application.
