An Avatar-based Interface for the Italian Sign Language

In this paper, we describe a virtual interpreter of the Italian sign language (Italian Sign Language, LIS). developed as part of the on--going ATLAS project, on the automatic translation from Italian to Italian Sign Language. The translation system communicates with the user through a virtual signer: the system takes as input a formal representation of a sign language sentence and produces the corresponding animation of the avatar. The architecture of the virtual signer consists of a resource planner, an executor of the planned sign animations, and an animation system.
