Physical touch, such as handshakes, plays a critical role in human-robot interaction (HRI), influencing perceived naturalness and social presence. This study investigates how arm compliance, hand grip strength, and motion synchrony jointly affect the subjective quality of a human-robot handshake. We…
Humor is a key element in human interactions, essential for building connections and rapport. To enhance human-robot communication, we developed a humor-aware chat framework that enables robots to deliver contextually appropriate humor. This framework takes into account the interaction environment,
This paper investigates how different levels of information impact user trust and cognitive load in teleoperated robotic systems. Participants performed tasks under three conditions: (C1) minimal information after initial visual feedback, (C2) verbal guidance through a graphical interface, and (C3)
Engagement is a key concept in Human-Robot Interaction (HRI), as high engagement often leads to improved user experience and task performance. However, accurately estimating engagement during interactions is challenging. In this study, we propose a Dynamic Bayesian Network (DBN) to infer user engage
Social robots have shown significant potential in enhancing learning experiences, and humor has been proven to be beneficial for learning. This study investigates the impact of both the presence and timing of humor on students’ learning outcomes and overall learning experience. A total of 24 partici
Nonverbal communication plays a crucial role in both human-human and human-robot interactions (HRIs), where facial expressions convey emotions, intentions and trust. Enabling humanoid robots to generate human-like facial reactions in response to human speech and facial behaviours remains significant
Trust plays a crucial role in user performance during collaborative human-robot interaction. This study examines how varying levels of autonomy and system errors affect user trust and cognitive load in collaborative tasks between robots and humans. Participants performed a collaborative task using a
Teleoperated robots, especially in hazardous environments, integrate human cognition with machine efficiency, but can increase cognitive load, causing stress and reducing task performance and safety. This study examines the impact of the information available to the operator on cognitive load, physi…
Companion robots are more and more taking the role of caregivers for elderly people. Elderly people sometimes take the advice given by their family members or caregivers as a criticism. In this context, persuasive communication skills could be helpful. A social psychology theory called Regulatory Fo…
This paper investigates how individuals react in a situation when an experimenter (human or robot) either tells them to stop in the middle of playing the Jenga game, or accidentally bumps into a table and makes the tower fall down. The mood of the participants and different physiological parameters…
In human-human interaction, three modalities of communication (i.e., verbal, nonverbal, and paraverbal) are naturally coordinated so as to enhance the meaning of the conveyed message. In this paper, we try to create a similar coordination between these modalities of communication in order to make th…
