• Title: Transferring Studies Across Embodiments: A Case Study in Confusion Detection
• Authors: Na Li and Robert Ross
• Abstract summary: Human-robot studies are expensive to conduct and difficult to control. As such researchers sometimes turn to human-avatar interaction in the hope of faster and cheaper data collection. This work shows that despite attitudinal differences and technical control limitations, there were a number of similarities detected in user behaviour. This work suggests that, while avatar interaction is no true substitute for robot interaction studies, sufficient care in study design may allow well executed human-avatar studies to supplement more challenging human-robot studies.

• Abstract: Human-robot studies are expensive to conduct and difficult to control, and as such researchers sometimes turn to human-avatar interaction in the hope of faster and cheaper data collection that can be transferred to the robot domain. In terms of our work, we are particularly interested in the challenge of detecting and modelling user confusion in interaction, and as part of this research programme, we conducted situated dialogue studies to investigate users' reactions in confusing scenarios that we give in both physical and virtual environments. In this paper, we present a combined review of these studies and the results that we observed across these two embodiments. For the physical embodiment, we used a Pepper Robot, while for the virtual modality, we used a 3D avatar. Our study shows that despite attitudinal differences and technical control limitations, there were a number of similarities detected in user behaviour and self-reporting results across embodiment options. This work suggests that, while avatar interaction is no true substitute for robot interaction studies, sufficient care in study design may allow well executed human-avatar studies to supplement more challenging human-robot studies.

  We present an experimental evaluation of ROS-Causal, a ROS-based framework for causal discovery in human-robot spatial interactions. We show how causal models can be extracted directly onboard by robots during data collection. The online causal models generated from the simulation are consistent with those from lab experiments.

  We aim to identify the nonverbal cues and computational methodologies resulting in effective performance. This survey differs from its counterparts by involving the widest spectrum of social phenomena and interaction settings. Some major observations are: the most often used nonverbal cue, computational method, interaction environment, and sensing approach are speaking activity, support vector machines, and meetings composed of 3-4 persons equipped with microphones and cameras, respectively.

  In social robotics, endowing humanoid robots with the ability to generate bodily expressions of affect can improve human-robot interaction and collaboration. We implement a deep learning data-driven framework that learns from a few hand-designed robotic bodily expressions. The evaluation study found that the anthropomorphism and animacy of the generated expressions are not perceived differently from the hand-designed ones.

  Partial subtle mirroring of nonverbal behaviors during conversations (also known as mimicking or parallel empathy) is essential for rapport building. Our research question is whether integrating an ECA able to mirror its interlocutor's facial expressions and head movements with a human-service robot will improve the user's experience. Our contribution is the complex integration of an expressive ECA, able to track its interlocutor's face, and to mirror his/her facial expressions and head movements in real time, integrated with a human support robot.

We propose a method to augment the training set with observational data of other agents, such as humans.
