The behavior of a social robot is designed based on either its emotional state or social situation. In this research, we defined these expressions as the affective and social expressions, and proposed a new emotional expression method to integrate these two expressions. It is known that a human has involuntary facial muscles around the eyes, and voluntary facial muscles around the mouth. Thus, it is considered that facial muscles around the eyes express the affective expressions, while facial muscles around the mouth express the social expressions. In an experiment involving a human-robot conversation, using the proposed method, the results showed a sense of human likeness and sociality. Furthermore, the intimacy evaluation results showed that the social expressions work effectively when the intimacy does not require high social bonding such as the desire for friendship. However, the affective expressions are necessary for evaluating intimacy that requires higher social bonding, such as wanting to live with someone.

Theatrical approach: Designing human-like behaviour in humanoid robots 査読有り

A key challenge in designing humanoid robots is producing natural and human-like behaviour. This study addressed this challenge by developing an instructive interface to design natural and human-like behaviour in a humanoid robot that will be helpful not only for professional robot motion designers but also for nonprofessionals. A staging method called contemporary colloquial theatre theory has been developed in the field of theatre to reproduce the natural behaviour of humans. Based on the theory, to design robot behaviour, we extracted implicit knowledge from a director's instructions given to a robot actor in a robot theatre project, where the robot functions as an actor and interacts with human actors. This paper shows the validity of applying this knowledge extraction method by means of a public stage play entitled Night On The Milky Way Train and two short plays created for the purpose of carrying out an analysis. Our analysis produced important rules for designing the behaviour of humanoid robots. The rules were extracted in forms suited to the instructive function of the interface. In this paper, we report the results of a subjective experiment conducted to verify the effectiveness of this function. Our experimental results suggest that the rules derived are effective in improving robot behaviour. (C) 2016 Elsevier B.V. All rights reserved.

Android robots as in-between beings

Kohei Ogawa, Hiroshi Ishiguro

Cognitive Science and Technology 頁： 327 - 337 2016年

記述言語：英語掲載種別：論文集(書籍)内論文出版者・発行元：Springer International Publishing

The Geminoid is an android robot based on an existing person and it can act as an avatar of the original person using a teleoperation system. The Telenoid is another android which is characterized by implementing a minimal design representation of a human. By this design, the Telenoid allows people to feel as if a spatially distant acquaintance is close-by. We created two artworks with the Geminoid through collaborations with artists. Firstly, we conceived the Android Theater. In Android Theatre human actors and androids shared the stage in a first play of its kind worldwide. The second work is an “Intelligent Mannequin”. Here the Geminoid was interacting with the visitors in a department store as an interactive mannequin. In this chapter, we give an overview of the Geminoid and the Telenoid, describing its appearance, teleoperation system and the concept of Android Science. We then focus on the artworks.

Future roles for android robots-survey and trial 査読有り

Tomoya Hoshikawa, Kohei Ogawa, Hiroshi Ishiguro

HAI 2015 - Proceedings of the 3rd International Conference on Human-Agent Interaction 頁： 41 - 48 2015年10月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：Association for Computing Machinery, Inc

The future role of android robots is discussed. Survey results reveal that people are capable of viewing androids as companions and will accept androids operating in various roles within human society
however, people are uncomfortable with androids operating in roles in which they are able to persuade humans to do something, affect humans' minds, or supervise young children. To examine people's response to an actual android robot within human society, an android capable of operating as "lecturer" was implemented and an evaluative experiment conducted. It was found that androids can evoke feelings of attentiveness that are much stronger than those evoked by existing media. Furthermore, use of the lecturer android did not improve efficiency. It is possible that people expected the android to have human-like abilities because of its human-like appearance. However, regardless of the cause, it is clear from the experiment that it is necessary to program androids with more human-like functions if they are to fill useful roles within human society.

Can androids be salespeople in the real world? 査読有り

Miki Watanabe, Kohei Ogawa, Hiroshi Ishiguro

Conference on Human Factors in Computing Systems - Proceedings 18 巻頁： 781 - 788 2015年4月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：Association for Computing Machinery

The roles of robots in the real world have become more diverse depending on their bodily properties. In this study, we aim to determine the roles that androids, whose bodily properties resemble humans, could serve in the real world. Selling and purchasing are common human activities. Therefore, we proposed the use of an android as a salesperson with cognitive and affective strategies utilizing the advantages of online-and counter-selling methods. We conducted a field study to investigate whether androids could sell goods in a department store. As a result, our sales strategies worked well and the android could sell 43 sweaters that cost approximately 100 dollars each for 10 days. These results are important knowledge for determining how androids may serve new roles and communicate with humans in the real world.

Relieving Mental Stress of Speakers using a Tele-Operated Robot in Foreign Language Speech Education 査読有り

Shizuka Nakamura, Miki Watanabe, Yuichiro Yoshikawa, Kohei Ogawa, Hiroshi Ishiguro

16TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION (INTERSPEECH 2015), VOLS 1-5 頁： 1835 - 1838 2015年

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：ISCA-INT SPEECH COMMUNICATION ASSOC

In an effort to relieve the mental stress experienced by speakers in foreign language speech education classes, an experiment using a tele-operated robot was conducted and its effect was evaluated. The robot was utilized in the following class environment: the teacher and classmates were not able to see the actual appearance of the speaker; however, the speaker could visually recognize the tele-operated robot speaking as its proxy, and was aware of the fact that the teacher and classmates also recognized the situation. The results of statistical analysis of subjective evaluation by the speakers to evaluate the effect on stress show that the degree of stress in speakers was lower when conversations with the teacher were conducted indirectly via the robot than doing so directly. A similar tendency is indicated by the results of subjective evaluation by the listeners in this experiment to imagine the case that they themselves are speakers. These results confirm that it is possible to relieve the mental stress experienced by speakers by utilizing a tele-operated robot.

The Uncanny in the Wild. Analysis of Unscripted Human-Android Interaction in the Field 査読有り

INTERNATIONAL JOURNAL OF SOCIAL ROBOTICS 6 巻 ( 1 ) 頁： 67 - 83 2014年1月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：SPRINGER

Against the background of the uncanny valley hypothesis we investigated how people react towards an android robot in a natural environment dependent on the behavior displayed by the robot (still vs. moving) in a quasi-experimental observational field study. We present data on unscripted interactions between humans and the android robot "Geminoid HI-1" in an Austrian public cafe and subsequent interviews. Data were analyzed with regard to the participants' nonverbal behavior (e.g. attention paid to the robot, proximity). We found that participants' behavior towards the android robot as well as their interview answers were influenced by the behavior the robot displayed. In addition, we found huge inter-individual differences in the participants' behavior. Implications for the uncanny valley and research on social human-robot interactions are discussed.
