Collaboration in three-dimensional space: “spatial workspace collaboration” is introduced and an approach supporting its use via a video mediated communication system is described. Verbal expression analysis is primarily focused on. Based on experiment results, movability of a focal point, sharing focal points, movability of a shared workspace,(More)
An information-presenting robot is expected to establish an appropriate spatial relationship with people. Drawing upon sociological studies of spatial relationships involving "F-formation" and "body torque," we examined the effect of a robot rotating its body on the reconfiguration of the F-formation arrangement. The results showed that a robot can change(More)
An approach supporting spatial workspace collaboration via a video-mediated communication system is described. Based on experimental results, the following were determined to be the system requirements to support spatial workspace collaboration: independency of a field of view, predictability, confidence in transmission and sympathy toward the system.(More)
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 robotic system that employs embodied resources such as face and head movement, we cannot simply program the(More)
The Wearable Active Camera/Laser (WACL) allows the remote collaborators not only to independently set their viewpoints into the wearer’s workplace but also to point to real objects directly with the laser spot. In this paper, we report an user test to examine the advantages and limitations of the WACL interface in remote collaboration by comparing a(More)
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 follows. We first examined human head gestures through an experimental, sociological approach. From this(More)
In this paper we investigated systems for supporting remote collaboration using mobile robots as communication media. It is argued that the use of a remote-controlled robot as a device to support communication involves two distinct ecologies: an ecology at the remote (instructor's) site and an ecology at the operator's (robot) site. In designing a robot as(More)
When designing systems that support remote instruction on physical tasks, one must consider four requirements: 1) participants should be able to use non-verbal expressions, 2) they must be able to take an appropriate body arrangement to see and show gestures, 3) the instructor should be able to monitor operators and objects, 4) they must be able to organize(More)
