In our previous research, we proposed a voice call system with robots to initiate conversations between remote people by exchanging gaze information. In the proposed system, we implemented robots that can detect and present gaze as awareness ...

In this study, the nature of human trust in communication robots was experimentally investigated comparing with trusts in other people and artificial intelligence (AI) systems. The results of the experiment showed that trust in robots is basically ...

Nowadays, decreasing opportunities for people to have daily conversations due to the increase in the number of withdrawn young people and households living alone. The lack of daily conversation has been pointed out as a risk that can lead to mental ...

Robots communicating with humans have been widely utilised in our society. This type of communication can be limited when only one robot is involved. Meanwhile, expressing the same unified mood and emotion is difficult when several robots are working. ...

The purpose of this study was to propose a model of development of trust in social robots. Insights in interpersonal trust were adopted from social psychology and a novel model was proposed. In addition, this study aimed to investigate the relationship ...

In human-robot communication, humans appear to have difficulty ending their conversations with robots due to a certain consideration toward the robot itself. Thus, verbal and nonverbal cues in robot behaviors are critical to ease conversational closure. ...

Additive manufacturing, the academic term of 3D-Printing, is the way of fabricating new objects by adding materials layer-by-layer. Our team extended this technology to the next level enabling users to add materials directly onto ready-made (3D-printed) ...

We are using information communication technology and communication robots (hereafter referred to as "robots") to develop a service to assist recreational activities at nursing homes. The service relies on visual content to deliver a variety of ...

Numerous studies have examined communication robots that communicate with people, but it is difficult for robots to communicate with people smoothly. We call the communication style based on dialogue between robots as "human-robot implicit communication"...

Today there is much information and knowledge on the internet, and many studies have examined the extraction of many kinds of knowledge from the internet. In addition, numerous studies have examined entertainment robots that communicate with people, but ...

In a tele-operated robot system, the reproduction of auditory scenes, conveying 3D spatial information of sound sources in the remote robot environment, is important for the transmission of remote presence to the tele-operator. We proposed a tele-...

In Japan, which has already become a super aging society, it is important that elderly people maintain their healthy condition both physically and mentally. We have developed a portable robot, "TechTech," which encourages them to take a walk. We infer ...

Health care costs and ageing population are two factors which are of major concern to western governments in the 21st century. Existing work in affective health care is primary focused on developing avatars in the tele-health space. This paper reports ...

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 ...

This paper proposes an environmental sensor bridge system named COSPI for autonomous communication robots. In the near future, various sensors will get installed in day-to-day environments and robots will use information from these sensors to recognize ...

This paper proposes an environmental sensor bridge system named COSPI for autonomous communication robots. In the near future, various sensors will get installed in day-to-day environments and robots will use information from these sensors to recognize ...

This paper describes a model for a robot to appropriately control its position when it presents information to a user. This capability is indispensable since in the future many robots will be functioning in daily situations as shopkeepers presenting ...

This paper introduces the possibilities of symbiosis between human and communication robots fromthe viewpoint of multi-modal interfaces. Current communication abilities of robots, such as speech recognition, are insufficient for practical use and needs ...

Expecting certain behaviors from users is essential when programming the actions of communication robots. However, an efficient way to bring forth this expectation has not been realized yet. To tackle this problem, this paper presents a novel sensor ...

This paper reports a method that uses humanoid robots as a communication medium. There are many interactive robots under development, but due to their limited perception, their interactivity is still far poorer than that of humans. Our approach in this ...
