This paper presents the effect of a robot's active touch for improving people's motivation. For services in the education and healthcare fields, a robot might be useful for improving the motivation of performing such repetitive and monotonous tasks as exercising or taking medicine. Previous research demonstrated with a robot the effect of user touch on improving its impressions, but they did not clarify...
Ensuring that a particular and unsuspecting member of a group is the recipient of a salient-item hand-over is a complicated interaction. The robot must effectively, expediently and reliably communicate its intentions to advert any tendency within the group towards antinormative behaviour. In this paper, we study how a robot can establish the participant roles of such an interaction using imitated...
Pointing gestures are a common and intuitive way to draw somebody's attention to a certain object. While humans can easily interpret robot gestures, the perception of human behavior using robot sensors is more difficult.
The Haptic Creature is a small, animal-like robot we have developed to investigate the role of touch in communicating emotions between humans and robots. This paper presents a study examining how successful our robot is at communicating its emotional state through touch. Results show that, regardless of the human's gender or background with animals, the robot is effective in communicating its state...
Human-Robot peer-based teams are evolving from a far-off possibility into a reality. Human Performance Moderator Functions (HPMFs) can be used to predict human behavior by incorporating the effects of internal and external influences such as fatigue and workload. The applicability of HPMFs to human-robot teams is not proven. The presented research focuses on determining the applicability of workload...
The paper describes our project whose final goal is to link remote classrooms by telerobotics. The first target is to offer children in Japan an opportunity to remote-control a robot placed in an US classroom, and participate in the classroom activities. By conducting field trials at nursery schools and language schools for children, we aim to identify and solve critical problems which might prevent...
Several machine learning techniques are used to model the behavior of children with autism interacting with a humanoid robot, comparing a static model to a dynamic model using hand-coded features. Good accuracy (over 80%) is achieved in predicting child vocalizations; directions for future approaches to modeling the behavior of children with autism are suggested.
This paper presents an anthropomorphic robot hand called Osaka-City-University-Hand II, which is an improved version of Osaka-City-University-Hand I. The cosmetic and the function of our proposed hand allow us to use the hand as a prosthetic hand in addition to as an open platform of robot hands for robotics research. Distributed tactile and force sensors are appended to the OCU-Hand II as a feedback...
Coupled degrees-of-freedom exhibit correspondence, in that their trajectories influence each other. In this paper we add evidence to the hypothesis that spatiotemporal correspondence (STC) of distributed actuators is a component of human-like motion. We demonstrate a method for making robot motion more human-like, by optimizing with respect to a nonlinear STC metric. Quantitative evaluation of STC...
This video presents a study on how a physical game based on a mobile robot can be used as a persuasive tool for promoting physical activity among elderly. The goal of the game is to take a ball from a robot, and afterwards try to hand it back while the robot moves. The robot records the behavior patterns of each individual player and gradually adapts the challenge of the game to the player's skill...
Environment attributes are perceived or remembered differently according to the perspective used. In this study, two different perspectives, a survey perspective and a route perspective, are explained and discussed. This paper proposes an approach for modeling human environments from a route perspective, which is the perspective used when a human navigates through the environment. The process for...
This paper presents our approach to using semantic technologies to describe robot embodiments. We introduce a prototype implementation of RoboDB, a robot database based on semantic web technologies with the functionality necessary to store meaningful information about the robot's body structure. We present a heuristic evaluation of the user interface to the system, and discuss the possibilities of...
By initiating physical contact with people, robots can be more useful. For example, a robotic caregiver might make contact to provide physical assistance or facilitate communication. So as to better understand how people respond to robot-initiated touch, we conducted a 2x2 between-subjects experiment with 56 people in which a robotic nurse autonomously touched and wiped the subject's forearm. Our...
Assistive robots can be perceived in two main ways: tools or partners. In past research, assistive robots that offer physical assistance for the elderly are often designed in the context of a tool metaphor. This paper investigates the effect of two design considerations for assistive robots in a partner metaphor: conversation and robot-type. The former factor is concerned with whether robots should...
The present project aimed to study how people make moral judgment for human versus robot behaviors. Ten transgression scenarios were presented to the participants with either a human or a robot as the perpetrator or the victim. Results showed that most of the transgressions were perceived as less immoral when it was acted on a robot than on a human. Moral judgments for human behaviors were more intuitive...
Telepresence robots are becoming increasingly popular and are increasingly ready to enter use in the real world as standins for remote humans. It is useful, but currently uncommon, to provide the human operator with an approximation of peripheral vision and the ability to saccade around the scene. We have developed an interface which provides peripheral vision to a remote operator by using a motorized...
When a robot is said to be a specialist in a particular domain, does it alter the nature and quality of human-robot interaction? This study examines the effects of specialization in robot functions, along with individual difference in immersive tendencies, on users' trust, perception, activity, and memory. In a controlled experiment, 38 participants were taught a physical exercise lesson from either...
Conference proceedings back matter may contain various advertisements, indexes, and other miscellaneous conference information. This may in some cases also include committee or program information, blank pages, venue maps or other general information relating to the conference that was part of the original conference proceedings.
This year's conference focuses on human-robot interaction in the real world. The panel discussion presents the view from those who are “living it”: industry leaders who are relying on current robotic technology to accomplish their work right now. Who better to provide the most compelling information on issues/challenges that are influencing their use? This panel gathers experts from business and industry...
