A 3D application to discover French Sign Language! Vocabulary : The Lexicon lists over 100 French Sign Language signs and allows the viewer to see the avatar put the words into action. Several control buttons allow you to slow down the motion, to view the hand movements through colorful trajectories and there is also an option where you can see through the avatar allowing you to understand more easily how to recreate the sign yourself. You also have the choice of 5 avatars : a cat, a panda, a dog, a mouse and a fox. Mini games : A few mini games are available to help you to practice your vocabulary. The 'Devine le signe' game will ask you to choose the correct sign made by the avatar. The 'Memo-Signes' game will ask you to find the identical FSL pairs. All the 3D animations from this app are movements recorded from a deaf signer using motion capture technology.
