Data-Driven Communicative Behaviour Generation: A Survey

Abstract

The development of data-driven behaviour generating systems has recently become the focus of considerable attention in the fields of human-agent interaction (HAI) and human-robot interaction (HRI). Although rule-based approaches were dominant for years, these proved inflexible and expensive to develop. The difficulty of developing production rules, as well as the need for manual configuration in order to generate artificial behaviours, places a limit on how complex and diverse rule-based behaviours can be. In contrast, actual human-human interaction data collected using tracking and recording devices makes human-like multimodal co-speech behaviour generation possible using machine learning and specifically, in recent years, deep learning. This survey provides an overview of the state-of-the-art of deep learning-based co-speech behaviour generation models and offers an outlook for future research in this area.
