Identifying and Detecting Inadvertent Socially Inappropriate Movement of Avatar Robots

Avatar robots are telepresence robots that allow people to project themselves physically in distant places. Teleoperators use such avatars to have remote social interactions. Mobility adds to their interactive capabilities. However, it also presents challenges in social spaces; for instance, teleoperators can mistakenly move their avatars in a socially inappropriate manner. Since these robots have yet to become ubiquitous, there is little real-world data to objectively analyze the presence and frequency of such undesirable movement. Consequently, the different ways such movements manifest are unknown, and their occurrence cannot be detected. To address this problem, we conducted a laboratory experiment with hired participants in a replica artwork exhibition so that we could gather realistic human-avatar interaction data using sensors. Our data analysis helped us identify three types of inadvertently inappropriate movement behavior. We present a definition of such behavior based on these three inappropriate movement types and a labeled dataset containing more than 400 interactions, 18% of which were inappropriate. We also present detection models for each inappropriate movement type trained using our dataset.
