Australian sign language, Auslan, uses a combination of hand shapes, positions and movements, as well as facial expressions to communicate. Our ongoing research is to develop an automatic translator that graphically translates English to Auslan. Currently, we have implemented object-oriented C++ graphics libraries to build a whole upper body model. The model is a kinematic tree that allows physiologically possible movements that are necessary for Auslan sign display. We have experimented with two angle representations: Euler and quaternion. Using interpolation algorithms, we determined that the quaternion angle representation is more reliable than the Euler angle representation. This paper presents the design and implementation of the Auslan Jam system and our research into angle representation techniques. It also discusses future development of the model and the sign translator interface, and identifies possible improvements.
