The paper considers recognition of single sentences of the Polish Sign Language. We use a canonical stereo system that observes the signer from a frontal view. Feature vectors take into account information about the hand shape and orientation, as well as 3D position of the hand with respect to the face. Recognition based on human skin detection and hidden Markov models (HMMs) is performed on line. We focus on 35 sentences and a 101 word vocabulary that can be used at the doctor's and at the post office. Details of the solution and results of experiments with regular and parallel HMMs are given.
