The field of human-robot interaction (HRI) is increasingly focusing on enhancing the quality and depth of interactions between humans and robots, with a particular emphasis on understanding, rapport, and safety. Recent developments have introduced innovative methodologies and tools to measure and improve these aspects, indicating a shift towards more nuanced and sophisticated HRI systems.

One significant advancement is the development of scales and frameworks to quantitatively assess human-robot rapport, highlighting the importance of mutual understanding and interpersonal connection in successful long-term interactions. Additionally, there is a growing interest in leveraging conversational AI to improve robot understanding and communication, suggesting a move towards more adaptive and explainable HRI systems.

Safety and efficiency in robot action planning, especially in environments with unconcerned humans, have also seen progress. New planning schemes that incorporate predictive models of human behavior and awareness are being developed to ensure safer and more efficient interactions.

Moreover, the role of social communications, such as small talk, in human-robot collaboration is being explored. This research underscores the potential of non-task-oriented interactions to enhance rapport and interaction dynamics, even in industrial settings.
