Abstract
Virtual humans still lack naturalness in their nonverbal behaviour. We present a data-driven solution that moves towards a more natural synthesis of hand and arm gestures by recreating gestural behaviour in the style of a human performer. Our algorithm exploits the concept of gesture units to make the produced gestures a continuous flow of movement. We empirically validated the use of gesture units in the generation and show that it causes the virtual human to be perceived as more natural.
