We evaluate the effectiveness of the type of directions given by a robot in a joint-activity task. The joint-activity task we focus on involves a humanoid robot giving directions to a human subject in exploring an unknown environment and finding objects ...

Navigation robots have the potential to overcome some of the limitations of traditional navigation aids for blind people, specially in unfamiliar environments. In this paper, we present the design of CaBot (Carry-on roBot), an autonomous suitcase-shaped ...

In order to be successful, guide robots in public space require socially-intelligent navigation behaviors. Evaluation of these behaviors can be done through lab studies, though these do not always capture the complexities of interactions in "the wild". ...

This paper describes current work toward the design of a guide robot system. We present a method to recognize people's interest and intention from their walking trajectories in indoor environments, which enables a service robot to proactively approach ...

We report intermediate results of an ongoing study into the effectiveness of robot gaze behaviors when addressing multiple persons. The work is being carried out as part of the EU FP7 project FROG and concerns the design and evaluation of interactive ...

In this paper, we present our work designing a robot that explains an exhibit to multiple visitors in a museum setting, based on ethnographic analysis of interactions between expert human guides and visitors. During the ethnographic analysis, we ...

A robust and adaptive person-following behaviour is an important ability that most service robots must have to be able to face challenging illumination conditions, and crowded spaces of nonstructured environments. In this paper, we propose a system ...

As a testbed for real-world experimentation on HRI and dynamic interaction models, this paper presents an autonomous robot system acting as guide in a German arts museum. The visitors' evaluation of this system is analyzed using a questionnaire and ...

This paper presents a method of selecting the answerer from audiences for a museum guide robot. We performed the preliminary experiments that a robot distributed its gaze towards visitors to select an answerer and analyzed visitors' responses. From ...

Designing technologies that support the explanation of museum exhibits is a challenging domain. In this paper we develop an innovative approach - providing a robot guide with resources to engage visitors in an interaction about an art exhibit. We draw ...

As research over the last several decades has shown that non-verbal actions such as face and head movement play a crucial role in human interaction, such resources are also likely to play an important role in human-robot interaction. In developing a ...

We are currently working on a museum guide robot with an emphasis on "friendly" human-robot interaction displayed through nonverbal behaviors. In this paper, we focus on head gestures during explanations of exhibits. The outline of our research is as ...
