Taxonomy of Trust-Relevant Failures and Mitigation Strategies

We develop a taxonomy that categorizes HRI failure types and their impact on trust to structure the broad range of knowledge contributions. We further identify research gaps in order to support fellow researchers in the development of trustworthy robots. Studying trust repair in HRI has only recently been given more interest and we propose a taxonomy of potential trust violations and suitable repair strategies to support researchers during the development of interaction scenarios. The taxonomy distinguishes four failure types: Design, System, Expectation, and User failures and outlines potential mitigation strategies. Based on these failures, strategies for autonomous failure detection and repair are presented, employing explanation, verification and validation techniques. Finally, a research agenda for HRI is outlined, discussing identified gaps related to the relation of failures and HR-trust

M.J.: Encouraging physical therapy compliance with a hands-off mobile robot

This paper presents results toward our ongoing research program into hands-off assistive human-robot interaction [6]. Our work has focused on applications of socially assistive robotics in health care and education, where human supervision can be significantly augmented and complemented by intelligent machines. In this paper, we focus on the role of embodiment, empirically addressing the question: “In what ways can the robot’s physical embodiment be used effectively to positively influence human task-related behavior?” We hypothesized that users ’ personalities would correlate with their preferences of robot behavior expression. To test this hypothesis, we implemented an autonomous mobile robot aimed at the role of a monitoring and encouragement system for stroke patient rehabilitation. We performed a pilot study that indicates that the presence and behavior of the robot can influence how well people comply with their physical therapy.

Natural person-following behavior for social robots

We are developing robots with socially appropriate spatial skills not only to travel around or near people, but also to accompany people side-by-side. As a step toward this goal, we are investigating the social perceptions of a robot’s movement as it follows behind a person. This paper discusses our laser-based person-tracking method and two different approaches to person-following: direction-following and path-following. While both algorithms have similar characteristics in terms of tracking performance and following distances, participants in a pilot study rated the direction-following behavior as significantly more humanlike and natural than the path-following behavior. We argue that the path-following method may still be more appropriate in some situations, and we propose that the ideal personfollowing behavior may be a hybrid approach, with the robot automatically selecting which method to use

Interactions with a Moody Robot

ABSTRACT This paper reports on the results of a long-term experiment in which a social robot's facial expressions were changed to reflect different moods. While the facial changes in each condition were not extremely different, they still altered how people interacted with the robot. On days when many visitors were present, average interactions with the robot were longer when the robot displayed either a "happy" or a "sad" expression instead of a neutral face, but the opposite was true for low-visitor days. The implications of these findings for human-robot social interaction are discussed

Copyright is held by the author/owner(s). AVIVA: A Health and Fitness Monitor

In this paper we describe AVIVA, a prototype health and fitness monitor for young women. The device helps and encourages the user to balance the many aspects of attaining good health, including nutrition, exercise, and the social aspects of health. We describe the process used in developing the AVIVA monitor as well as our final design
