　View Summary

Werewolf is one of the popular communication games all over the world. It treats ambiguity of human discussion including the utterances, gestures and facial expressions in a broad sense. In this research, we pay attention to this imperfect information game werewolf. The purpose of the research is to develop an intelligent agent "AI werewolf" which is enabled to naturally play werewolf with human. This paper aims to investigate how behavior contribute to victory of own-side players by using machine learning as a first step. As the results of investigation and analysis of the playing movie, we found that nonverbal information in the game of werewolf has importance to winning or losing the game.

　View Summary

Bullying is a serious problem, especially at elementary school and junior high school and occurs all over the world with some differences. As a countermeasure against bullying, many interventions and preventive programs were proposed (e.g., counseling, dispatch of advisers, group work, suspension order) and there are many researches about analysis of bullying and intervention and preservation strategies. However, a lot of samples and long times are required for analysis of the strategies in the real world. And we believe simulations of the bullying and the countermeasures are effective as a quick and easy analysis. In this paper, we developed a simulation model of school bullying "within-group" or "within-class" that is based on "Socion theory". The primary feature of "Socion theory" is that each agent has an imagined personal relationship. We implemented a strategy named conforming strategy to simulate the bullying caused by conforming behaviors of students. The student agents who implement the conforming strategy watch the human relationship around them and update their own imagined relationships. Then they conform to other students to get good positions or keep their grounds on the basis of simulation results based on their own imagined relationships. The result of the experiment shows the conforming strategy increases the probability of bullying and the number of victims, and conforming behaviors increase the probability of bullying in the real world. We also show a state that a teacher underestimates or cannot perceive bullying when it occurred, and many teachers underestimate or cannot perceive bullying in the real world. Totally, we show that "Socion theory" has expressiveness to use as a foundation of bullying simulation.

　View Summary

Self-explanatory interface helps self-learning process of learner without third person explainer between learner and learned appliance. The learner need not to conscious about explainer during the learning process. This method sustains self-respect of each learner and continues motivation for learning. In this study, we proposes self-explanatory interface that changes the level of appearance according to user's attribute. We implemented several hardware to control anthropomorphic presence of home-appliance for supporting self-explanatory learning method.

　View Summary

本論文では，仮想的な身体を持つアバタを投影する遠隔コミュニケーションシステムPROT AVATARにおけるアバタ操作手法に関する実験をもとに，得られた知見について議論する．PROT AVATARによるコミュニケーションでは，アバタの操作者の映像を遠隔地に投影するため，表情により感情を伝えることができる．さらに，アバタの操作者にとっては明確ではない，アバタの投影に適切な位置をシステムが自動で計算するため，アバタの操作者は投影位置を考えることなく遠隔の環境内を指し示すことができる．しかし，アバタの操作者が採用する視点はアバタの視点とは異なることがあるため，アバタの操作者の発話がアバタとの対話者にとっては自然ではない場合がある．本論文では，アバタの操作手法として，自動操作手法と半自動操作手法の2つの手法を設計・実装し，比較実験を行った．実験の結果，半自動操作手法のほうが自動操作手法よりも，アバタとの対話者にとって自然な発話を引き出すことが示された．また，実験を通して得られた遠隔コミュニケーションシステム関する知見をまとめる．This paper discusses the findings of the viewpoint of an avatar-controlling user on the basis of experimentation with an implemented telecommunication system named PROT AVATAR. Communication using an avatar with facial expressions is useful when a user wants to express emotions. On top of this feature, our system supports avatar movement toward nearest visible location to the target, which is not obvious for the avatar controller. With our system, the avatar controller can easily refer to something remotely. However, sometimes, the words of an avatar controller may not be intuitive for an avatar viewer, because the avatar controller does not necessarily share the viewpoint of the avatar. We designed automatic and semi-automatic methods for controlling the avatar, and we conducted an experiment to compare the two methods. The results showed that semi-automatic control brought more intuitive utterances for an avatar viewer than fully automatic control, and they have design implications for telecommunication systems.

　View Summary

<p>In this paper, we propose to make intention drawing from system to human and collecting task between human and empty-box just by behaviors with two axis actuators. First, we extracted elements of minimum interaction model between user and empty-box using immersion discovering method based on Wizard of Oz method. Next, we designed three-state model based on findings. Third, we implemented three-state model by motion capture system, and confirms how collecting task was achieved. Last, we evaluated these models are indistinguishable from human manipulation using Turing-test based evaluation. </p>

Interaction with an agent in Blended Reality

Yusuke Kanai, Hirotaka Ohsawa, Michita Imai

ACM/IEEE International Conference on Human-Robot Interaction    153 - 154 2013

Joint Work, Accepted,  ISSN  2167-2148

　View Summary

This paper proposes a Blended Reality Agent called 'BReA' that can exist in both the real and virtual world and has communicative advantages that is more than simply the sum of those of a robotic agent and an on-screen agent. BReA can seamlessly transfer between the real world and virtual world and users can communicate with BReA without interruption during the transference. We conducted a field test and showed that users can recognize when it points from the virtual world to a real world object after it moves from the real world to virtual world. This result supports a hypothesis that communicating with BReA helps users recognize the link between real world and virtual world objects and virtual world information. © 2013 IEEE.

Joint Work, Accepted

　View Summary

FlashTouch is a new technology that enables data communication between touchscreen-based mobile devices and digital peripheral devices. Touchscreen can be used as communication media using visible light and capacitive touch. In this paper, we designed a stylus prototype to describe the concept of FlashTouch. With this prototype, users can easily transfer data from one mobile device to another. It eliminates the complexity associated with data sharing among mobile users, which is currently achieved by online data sharing services or wireless connections for data sharing that need a pairing operation to establish connections between devices. Therefore, it can prove to be of particular significance to people who are not adept at current software services and hardware functions. Finally, we demonstrate the valuable applications in online settlements via mobile device, and data communication for mobile robots. Copyright © 2013 ACM.
