What is Proactive Human-Robot Interaction? - A Review of a Progressive Field and Its Definitions

Abstract

During the past 15 years, an increasing amount of works have investigated proactive robotic behavior in relation to Human–Robot Interaction (HRI). The works engage with a variety of research topics and technical challenges. In this article, a review of the related literature identified through a structured block search is performed. Variations in the corpus are investigated, and a definition of Proactive HRI is provided. Furthermore, a taxonomy is proposed based on the corpus and exemplified through specific works. Finally, a selection of noteworthy observations is discussed.
