Analysis of gesture expressivity modulations from cartoons animations

In this paper, we describe a gesture expressivity analysis of a character in a conversational interaction. To determine gesture properties that attract and maintain perceptual attention, we study if there exists some effects in the field of gesture expressivity modulations. We study this role at a low level (gesture phase) and at a higher level (discourse structure) based on a corpus annotation of Tex Avery (MGM) cartoons. First results of the analysis point out synchronization properties between modulations and gesture phase or discourse structure.
