Avatars are virtual characters making the communication between user and machine more natural and interactive. The main advantage of using avatars within interfaces is to allow user to interact intuitively with the system by giving him the illusion of communicating with a real human. This illusion is obtained by mimicking human communication, i.e. giving avatar the ability of expressing emotions through facial and body language. We proposed the method based on multi-layered representation for a kind of 3D anthropomorphic avatar, and validated it as an information presenter. The way of controlling the avatar's emotion is to use parameterized facial muscle model and skeleton skinning, scheduled with multi-thread. Then a series of naturalistic avatar animation produced.
