The aim of this paper is to specify some of the problems raised by the design of a gesture recognition system dedicated to Sign Language, and to propose suited solutions. The three topics considered here concern the simultaneity of information conveyed by manual signs, the possible temporal or spatial synchronicity between the two hands, and the different classes of signs that may be encountered in a Sign Language sentence.
