Approaches that reduce the complexity of motions generated have also been proposed. In this paper, we describe ongoing development of a framework for Adaptive Level Of Detail for Human Animation (ALOHA), which incorporates levels of detail for not only geometry and motion, but also includes a complexity gradient for natural behaviour, both conversational and social.ACM CSS: I.3.7 Three-Dimensional Graphics and Realism-Animation10.1111/1467-8659.00631733-741
