Title
High-level Specification and Animation of Communicative Gestures
Abstract
This paper describes a complete system for the specification and the generation of visual communicative gestures. A high-level language for the specification of hand–arm communication gestures was developed. This language is based on both a discrete description of space, and a movement decomposition inspired by sign language gestures. Communication gestures are represented by symbolic commands that can be described by qualitative data, and translated in terms of spatio-temporal targets that drive the generation system. This approach is well-suited for a class of generation models controlled by key-points information at the trajectory level. The animation model used in our approach is composed of a set of sensory-motor control loops. Each of these models computes in real-time updated angular coordinates of the articulatory structure from the minimization of the distance between target and current locations. At the same time, psycho-motor laws of biological movement are satisfied. The whole control system is applied to the synthesis of communication and sign language gestures. A synthetic character is animated and some results are presented.
