Evaluation of Function Explaining from Artifacts using a Direct Anthropomorphization Method

OSAWA Hirotaka, OHMURA Ren, IMAI Michita

Journal of Human Interface Society (Human Interface Society) 10 ( 3 ) 11-20 - 314 2008

Research paper (scientific journal), Joint Work, Lead author, Corresponding author, Accepted, ISSN 1344-7262

<p>We propose a direct anthropomorphization method that agentize an artifact by attaching anthropomorphic parts to it. There are many studies to provide information to users using spoken directions and gestures via anthropomorphic agents such as CG agents and communication robots. Our method directly anthropomorphize the artifact through robotic bodily parts shaped like those of humans. The anthropomorphized artifact using these parts provides information to people by giving them spoken directions and expressing themselves through body language. Using these devices, people are able to accept more attentions to the artifact, than using anthropomorphic CG or robot agents. We conduct an experiment to verify a difference between explanation of fuctions of the artifact using direct anthropomorphization method and explanation of them using independent humanoid-agent "Robovie". The results of participants' questionnaires and gazes during the experiment indicate that they noticed to the target artifact and memorized functions using direct anthropomorphization method more than using independent humanoid-agent.</p>

Towards anthropomorphized spaces: Human responses to anthropomorphization of a space using attached body parts.

Hirotaka Osawa, Michita Imai

2008 17TH IEEE INTERNATIONAL SYMPOSIUM ON ROBOT AND HUMAN INTERACTIVE COMMUNICATION, VOLS 1 AND 2 (IEEE) 148 - 153 2008

This study investigated the effects of a method of anthropomorphizing a target space using attachable robotic human parts. As a result of this method, users may perceive a space as having lifelike characteristics and may accept a virtual body image for various objects. We developed robotic human parts to evaluate our method and conducted an experiment in which subjects positioned objects according to instructions given within an anthropomorphic space to determine their acceptance of the virtual body images presented and the anthropomorphic representation of the space. The results showed that subjects' positioning of objects changed according to the position of the human parts. We found that our method successfully generated a virtual body image for a particular region that would not normally be recognized in this way by users.

2P2-I12 Device Detecting Hands to Present the Information Based on the Area Humans Indicated

NODA Masato, OSAWA Hirotaka, IMAI Michita

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (The Japan Society of Mechanical Engineers) 2008 ( 0 ) _2P2-I12_1 - _2P2-I12_4 2008

qWe propose the device detecting the two-dimentional area human indicated by using the pyroelectric sensor. This device allows the information presentation for the area human indicated by the anthropomorphic object. For example, under explanation the function of electric appliances for customers in the shop, if customers indicate the worrisome area and the anthropomorphic electric appliance explains that area, information presentation can be more pertinent and visceral. Detection of the area is conducted by the output of pvroelecric sensors allocated in alignment.

ヒューマンオブジェクトインタラクションのための物体擬人化手法の評価

ISSN 13479881

本研究では，擬人化パーツを用いて物体を直接エージェント化する人間－物体間のインタラクション手法を提案し、ロボットなど擬人化エージェントを用いる従来の情報提示手法との違いを実験によって比較した．
実験後の回答結果より，ユーザは擬人的エージェントを介した情報提示よりも直接擬人化された物体からの情報提示をより多く記憶していることが分かった．

人間同士による繰り返し型囚人のジレンマゲームの実施と結果

大澤博隆, 今井倫太

ゲームプログラミングワークショップ2007論文集 2007 ( 12 ) 188 - 194 2007.11

本研究では，シミュレーション上で実施されることの多い繰り返し囚人のジレンマゲームを人間のプレイヤ同士で行わせ，各エージェントの戦略を，実際の人間プレイヤ同士にプログラムさせることで，ゲーム上でのエージェントの戦略の変化を調べる．これにより，実際の人間同士の集団ゲームにおいて，人間がどのように戦略を変化させていくか分析した．本研究では Axelrod の初回の大会の条件を元に，囚人のジレンマゲームの条件を設定し，大学の授業の課題として，授業参加者 72 人の人間を対象とし，25 日間の実験を行った．その結果，Axerlod の初回の大会や，シミュレーションの結果と異なり，上位のものほど記述が複雑化する傾向が発見された．また複数のプレイヤ同士が協力する「主人−奴隷戦略」，上記の戦術に対する寄生戦略，自身の勝利を目指さず，他プレイヤを追い落とす戦略など，一見すると合理的でない，様々な戦略が確認された．

本研究では，身体部品を取り付けて物体を直接擬人化し，情報提示を行うディスプレイロボットを提案する．ディスプレイロボットは目や手などの身体部品を持ち，取り付けられた位置や，取り付け状況にあわせた擬人化を行う．これにより，ユーザに対し取り付け対象の身体イメージを想起させつつ，周囲の環境情報や，物体があらかじめ備えた機能を身体イメージを通して変換し，ユーザにとってより理解し易い形で伝えることが出来る．本論文では，現在までに行ったディスプレイロボットの実装および，実装したロボットを実際の展示場で展示した際の，ユーザの評価結果について述べ，物体擬人化手法の効用について検討する．

Anthropomorphization Framework for Human-Object Communication

<jats:p>We propose an anthropomorphization framework that determines an object’s body image. This framework directly intervenes and anthropomorphizes objects in ubiquitous-computing environments through robotic body parts shaped like those of human beings, which provide information through spoken directions and body language. Our purpose is to demonstrate that an object acquires subjective representations through anthropomorphization. Using this framework, people can more fully understand instructions given by an object. We designed an anthropomorphization framework that changes the body image by attaching body parts. We also conducted experiments to evaluate this framework. Results indicate that the site at which an anthropomorphization device is attached influences human perception of the object’s virtual body image, and participants in experiments understood several instructions given by the object more clearly. Results also indicate that participants better intuited their devices’ instructions and movement in ubiquitous-computing environments.</jats:p>

"Display Robot" - Interaction between Humans and Anthropomorphized Objects.

Hirotaka Osawa, Jun Mukai, Michita Imai

2007 RO-MAN: 16TH IEEE INTERNATIONAL SYMPOSIUM ON ROBOT AND HUMAN INTERACTIVE COMMUNICATION, VOLS 1-3 (IEEE) 451 - 456 2007

Joint Work, Lead author, Corresponding author, Accepted

We propose a '' display robot '' that directly anthropomorphizes objects using body parts that are like those of humans. It is constructed of devices that look like eyes and arms. It anthropomorphizes objects according to the places they are located at or the situations they are in, and this increases their subjectivity and their virtual body image. The display robot enables users to accept the body images of objects and communicate smoothly with them. We assessed user evaluations of the display robot in an exhibition space and in this paper we discuss the effect of anthropomorphization achieved by these devices.

2A2-E04 Anthropomorphization framework for Human-Object Communication

OSAWA Hirotaka, MUKAI Jun, IMAI Michita

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (The Japan Society of Mechanical Engineers) 2007 ( 0 ) _2A2-E04_1 - _2A2-E04_4 2007

In this study, we propose anthropomorphization framework, which directly anthropomorphize an object by using human-like body parts. Nowadays, home appliances have many functions and tend to be connected together by a home network. This situation makes users feel uneasy as they need to understand more complex informations. Instead of improving the design or the interface of objects, we prefer to provide information via anthropomorphic and communicative agents, which seems to be more useful and user-friendly. Our framework transforms an object into an agent called displaying robot by using anthropomorphization, which makes the interaction between human and the object more intuitive. To verify our framework, we conducted an experiment to verify the effectiveness of anthropomorphization by attaching such eye-like and arm-like devices to a home appliance and implemented information providing system using our framework.

Acquisition of Body Image by Anthropomorphization Framework

Hirotaka,Osawa, Jun,Mukai, Michita,Imai

Joint 3rd International Conference on Soft Computing and Intelligent Systems and 7th International Symposium on advanced intelligent Systems (Japan Society for Fuzzy Theory and Intelligent Informatics) 2006 1460 - 1465 2006.09

Joint Work, Lead author, Corresponding author, Accepted

In this study, we propose anthropomorphization framework that determines object's body image by attaching it to human-like body parts. Our purpose is that an object acquires subjective representation by anthropomorphization and it communicates with humans. Although, there are many studies on anthropomorphic agents to communicate with humans via an object, it's unnatural because these agents are unrelated to the object directly. In our method, the object is directly anthropomorphized so it can conduct task-related communication using its intrinsic body image. We designed anthropomorphization framework that changes body image by attaching places of body parts. We also conducted an experiment to evaluate this framework. The result indicates that an attached place of anthropomorphize device influences human's perception for body image.
