Abstract
With the increase of multimedia content in the WWW multimodal presentation the use of interactive life-like agents is becoming important. However, it is not easy for many people to write such multimodal presentations, due to the complexity of describing various behaviors of the character agent and the interaction of the particular character system with the individual (often low-level) description language. In order to overcome this complexity and to allow more people to write attractive multimodal presentations easily MPML (Multimodal Presentation Markup Language) Version 1.0 has been developed to provide a medium-level description language commonly applicable to many character systems. Also, a new emotion expression function is attached to MPML. With this function, we are able to express emotion-rich behavior of the character agent in MPML Version 2.0e. We present a simple introduction to MPML Version 1.0, and present the new functions in Version 2.0e. Some multimodal presentation contents are produced in the new version of MPML to show the effectiveness of the new emotion function.
