This paper describes the synthesis of sign-language animation for mobile environments. Sign language is synthesized by using either the motion-capture or motion-primitive method. An editing system can add facial expressions, mouth shapes and gestures to the sign-language CG animation. Sign-language animation is displayed on PDA screens to inform the user of his/her mobile environment.

-This paper proposes a multi-classified and self-directed learning method used for sign language recognition, which adopts statistical template matching methods to recognize sign language. As sign language expressions consist of many frames, SIFT algorithm is used to position key frames and eigenvectors of sign language vocabulary. According to these key frames, the hierarchical discriminate re...

In the framework of a research target that aims at integration of sign language technologies to human-computer interaction applications, creation and annotation of the Greek Sign Language Corpus (GSLC) involve, on the one hand, data and analysis of the phonological structure of morphemes of Greek Sign Language (GSL) and, on the other hand, collection of sentence level language samples and assig...
