Analyzing and transcribing a sign language is a difficult task since the mode of expression - hand movements in a space located close to the body, complemented by attitudes and facial expressions - is a priori less sequential than speech. Our work aims to complete numerous previous attempts and uses in particular Stokoe’s system. Analysing the movement of a frame attached to the hand as the movement of a point in R 3 × S O ( 3 ) we manage to discretize in a natural way the most frequent gestures of...
