Robots at Arm’s Length

The paper „Robots at arm’s length: Unveiling the dynamics of interpersonal distance preferences in human-robot interactions“ by Katharina Kühne, Laura M. Zimmer, Melina Jeglinski-Mende, Oliver Bendel, Yuefang Zhou, and Martin H. Fischer was published in February 2025 in the proceedings volume „Social Robots with AI: Prospects, Risks, and Responsible Methods“ … From the abstract: „In social interactions, interpersonal distance is a vital factor influencing relationships, providing protection, and regulating arousal. Despite the intuitive nature of adopting specific distances, little is known about comfortable interpersonal distances with social robots. In our online study with 66 participants using a Go/No-Go task, we investigated perceptions of individuals standing face-to-face with a robot at different distances. In line with the negativity bias hypothesis, participants exhibited a preference for greater distances , as reflected in longer reaction times. Furthermore, the human-likeness of the robots moderated the link between distance and arousal. Finally, the most human-like robot was less liked and evoked higher arousal. These findings have implications for designing social robots and optimizing interactions, particularly in educational or medical contexts.“ The proceedings volume comprises the papers presented at Robophilosophy 2024 in Aarhus. Leading philosophers, computer scientists, and roboticists met there in August. Like the ICSR, the conference is one of the world’s leading conferences on social robotics.
