Conceptual Motorics Generation And Evaluation Of Communicative Robot Gesture

How do humans perceive communicative gesture behavior in robots? Although gesture is a crucial feature of social interaction, this research question is still largely unexplored in the field of social robotics. The present work thus sets out to investigate how robot gesture can be used to design and realize more natural and human-like communication capabilities for social robots. The adopted approach is twofold. Firstly, the technical challenges encountered when implementing a speech-gesture generation model on a robotic platform are addressed. The realized framework enables a humanoid robot to produce finely synchronized speech and co-verbal hand and arm gestures. In contrast to many existing systems, these gestures are not limited to a predefined repertoire of motor actions but are flexibly generated at run-time. Secondly, the achieved expressiveness is exploited in controlled experiments to gain a deeper understanding of how robot gesture might impact human experience and evaluation of human-robot interaction. The findings reveal that participants evaluate the robot more positively when non-verbal behaviors such as hand and arm gestures are displayed along with speech. Surprisingly, this effect was particularly pronounced when the robot's gesturing behavior was partly incongruent with speech. These findings contribute new insights into human perception of communicative robot gesture and ultimately support the presented approach of endowing social robots with such non-verbal behaviors.

This book constitutes the refereed proceedings of the 7th International Conference on Social Robotics, ICSR 2015, held in Paris, France, in October 2015. The 70 revised full papers presented were carefully reviewed and selected from 126 submissions. The papers focus on the interaction between humans and robots and the integration of robots into our society and present innovative ideas and concepts, new discoveries and improvements, novel applications on the latest fundamental advances in the core technologies that form the backbone of social robotics, distinguished developmental projects, as well as seminal works in aesthetic design, ethics and philosophy, studies on social impact and influence pertaining to social robotics, and its interaction and communication with human beings and its social impact on our society.

This book constitutes the refereed proceedings of the 5th International Conference on Social Robotics, ICSR 2013, held in Bristol, UK, in October 2013. The 55 revised full papers and 13 abstracts were carefully reviewed and selected from 108 submissions and are presented together with one invited paper. The papers cover topics such as human-robot interaction, child development and care for the elderly, as well as technical issues underlying social robotics: visual attention and processing, motor control and learning.

This monograph presents analyses of filled and unfilled pauses, cut-offs, repair, discourse markers and other phenomena often referred to as disfluencies in the context of advanced language learners' PowerPoint presentations. It adopts a multimodal perspective to demonstrate the functions of these elements in interaction. Paired with gaze shifts, pointing gestures and posture shifts, they act as facilitators of joint visual orientation, mutual understanding, and accountable actions. Therefore, this volume suggests the name cofluency to reflect their potential functionality. Cofluencies are essential elements of multimodal chunks and multimodal patterns, and these are building blocks of a multimodal turn-taking mechanism for presentations. These concepts are illustrated and discussed based on excerpts from naturally occurring classroom data.

This book constitutes the refereed proceedings of the Third International Conference on Social Robotics, ICSR 2011, held in Amsterdam, The Netherlands, in November 2011. The 23 revised full papers were carefully selected during two rounds of reviewing and improvement from 51 submissions. The papers are organized in topical sections on social interaction with robots; nonverbal interaction with social robots; robots in society; social robots in education; affective interaction with social robots; robots in the home.

Computational Human-Robot Interaction provides the reader with a systematic overview of the field of Human-Robot Interaction over the past decade, with a focus on the computational frameworks, algorithms, techniques, and models currently used to enable robots to interact with humans.
