Finding Origin Points for New Coordinate System Suitable for Sign Animation

This paper proposes new coordinate system suitable for denoting sign language motion. As the proposed coordinate system consists of polar coordinate systems whose origins are certain points of human body, postures shown on the system can be proportional for avatars with any possible shape and fit with existing subjective sign notation systems. This paper extracted coordinate origins from Japanese-Japanese Sign Language Dictionary via morphological analysis. Selected 85 points are successfully mapped on HANIM standard humanoid avatar.
