A sign language avatar is realized using OpenGL to make users easy to execute a 3D graphic application in various operating systems. Sign animation data is extracted from sign word database using a morpheme analyzer and applied not only to update of the position and the orientation of each body part, but also to generation of lip and jaw motion according to vowel. In addition, the avatar presents facial expression described by the combination of eyebrow shape, tear and face complexion. To generate smooth sign motion, we adopt an interpolation method between consecutive key frames and propose a search algorithm which quickly extracts sign animation data from sign word database.
