本稿では人型ロボットを用い、環境情報をセンサデータとして得て、その変化に応じてロボットに感覚的発話をさせたときの、発話同士をスムーズに繋げる方法を提案する。感覚的発話とは、例えば電気がついたことをセンサが察知すると、ロボットは「明るくなったね」と言い、感覚を人間に与えるものである。問題点として、ロボットに異なる動作を連続して行わせた際、その発話同士の繋がりが不自然になると、人間が話題同士の関係性を掴めなかった場合、円滑なインタラクションに支障を来たす可能性がある。そのため、本稿ではロボットに発話同士を繋げる言葉や動作を盛り込むことにより、インタラクションへの引き込みを試みる。

本研究では、人間が生まれつき持っている環境の擬人化能力を促進し、複雑な機器・環境情報を人間に理解可能な形に翻訳する、認知補助擬人化インタフェースの開発を目指す。我々人間は先天的に、形状、動作、反応時間などの人間を想起させる表出をトリガーとして、外界の環境に対し人間と同じような対話者を投影し、対象を理解する擬人化を不可避的に行っている。擬人化現象は、人間が性別・年齢・文化に関わらず普遍的に持っている能力と捉えられる。本研究では、既存の環境にセンサやアクチュエータを取り付け、これらの擬人化現象を部分的・選択的に再現してやることで、意図の共有や遅延許容など、社会的な対話者が持つと想定されうる性質の一部または全部を環境に付与し、ユーザと環境間のインタラクションを改善する。従来手法に加え社会的なチャンネルを環境に与えることで、今まで伝えづらかった機器の複雑な機能や内部状態遷移などを、人間の認知能力に収まる範囲で伝えることが可能になると考えられる。

本研究では言語の代わりに２軸のアクチュエータを使い、出力を人間同士が最低限意思疎通可能とみなせる範囲まで制限したチューリングテストを提案し、人間とエージェント間での意図伝達に必要な要素を検討する。まず、人間同士の対話を本デバイスを介して行い、意図伝達のための要素を検討した。次に、個々の要素をプログラム化し、物体を指示しユーザに運ばせるタスクを行い、要求された行動をユーザに行わせることが出来た。

Grounding Cyber Information in the Physical World with Attachable Social Cues.

Unpredictable user behaviors in a physical process represent one of the fundamental obstacles to the realization of a Cyber-Physical System. In this paper, we propose the use of social cues such as body shape, expressions, and verbal timing to control user behaviors in the physical world. Social cues can control user behaviors in both their spatial and temporal aspects. As a result, user actions become more predictable in a CPS. We consider how social cues restrict user behaviors by referring to a number of psychological, cognitive, and human-robot interaction studies, and we propose a model of restriction based on social cues. Using this model, we created hardware and software in order to realize attachable social cues, and we seek to demonstrate the effect of social cues using the example of home appliances.

Between real-world and virtual agents: the disembodied robot.

Joint Work, Accepted, ISSN 2167-2121

In this study, we propose a disembodied real-world agent and the study of the influence of this disembodiment on the social separation between the user and the agent. In order to give a clue to the user about the presence of the robot and to make possible a visual feedback, we decide to use independent robotic body parts that mimic human hands and eyes. This robot is also able to share real-world space with the user, and react to his presence, through 3d detection and oral communication. Thus, we can obtain an agent with an important presence while keeping good space efficiency, and as a result ban any existing social barrier.

Behaviors for Getting Conscious Responses

This paper investigates robot's behaviors to get voluntary conscious responses from users. Our final goal is to construct an asynchronous human-to-human communication mediated by a potable robot. The robot has a behavior system which makes the robot behave in response to the acquired conscious response. The system also enables the user to give the robot feedback at anytime and anywhere while the robot presents a script which an author prepared. We investigate how well the behavior system encourages the users to give the robot feedback and how much the users consider inputting the response to be meaningful. The results show that there are definite relation between response behavior and the acquisition of the conscious responses.

An unobtrusive measurement tool is important for Human-Robot Interaction (HRI) research that does not want to attach markers or devices on the experiment subjects. This property allows a natural observation of interaction between human and robot during the experiment. In HRI, an experiment that involves with psychological evaluation usually requires physical measurement for evaluating the interaction, for instance, distance, direction, and approaching speed between human and robot. Low-profile Evaluation System (LES) is an ongoing work in creating an unobtrusive measurement tool for HRI research that provides 3D video recording, playback and measurement inside 3D scene in real-time. LES is designed to operate on a single computer to make setup and experiment outside laboratory environment easier. The demonstration in the real-word setup shows that LES provides acceptable 3D measurement accuracy for HRI research. © 2011 IEEE.

Who explains it?: avoiding the feeling of third-person helpers in auditory instruction for older people.

Hirotaka Osawa, Jarrod Orszulak, Kathryn M. Godfrey, Seiji Yamada, Joseph F. Coughlin

Auditory instruction is a well used method for people of all ages because of its understandability. However the additional voice has the possibility to disturb the user's learning during the instruction because it strongly implies the support of third-person helpers. This risk increases with older people because their confidence in their ability may decline compared to the younger people. The authors propose a method to anthropomorphize an instructed target (a vacuum) to decrease the feeling of a third person during instruction. The authors conducted the experiment using our method to explain features of household appliance and evaluated the relationship between recalled features and older people's internal scale. The results show that older people remembered more features by using our method, and with female participants, their internal scales increased during the training. This demonstrates that our method can decrease the third-person feeling in female participants and increase the amount learned. Our findings suggest that auditory instructions may be an effective learning method for older adults.
