Abstract：This paper introduces a hand model with constraints on it based on the analysis of hand structure and joints motion.According to the defined constraints and motion type,the data structure suitable for the synthesis of hand motion has been created.And also the neural network theory has been applied to hand motion distinguishing and it works fine.
