For increase of sign language TV programs, we have been conducting research on Japanese sign language (JSL) animation using TVML (TV program Making Language). We have already recorded about 7,000 JSL word motions and developed a method which can create natural JSL animation combining specified word motions smoothly. This paper describes a method which creates JSL animation using parts of motion data. Motion parts are cut out from word motions and managed separately. We have developed tools and experimented to analyze, edit and combine motion parts.
