子どもの学習障害，発達障害は，学習面のみならず，対人関係や運動面においても生じる様々な困難を緩和するために日常的に社会的なスキルを育成するための訓練を行う必要がある．従来訓練は，専門知識を持ったセラピストの同席，高価な機材が必要とされることが多く，頻繁に行えない問題がある．本研究では，伝統的なプレイセラピーをセンサとCGの連携によりデジタルデバイスとして拡張し，楽しみながら訓練に取り組める新しい訓練デバイスを提案する．本デバイスは，コミュニケーションの中でも特に話すこと聞くことを子どもに自然に促し，専門家でなくても話す聞くスキルを育成しやくすることを目的とした．本論文では，事前に開発した教材のプロトタイプを示し，専門家とのデバイスの機能の評価の指針と方法を議論した内容を述べた.

　View Summary

Children who are suffering on learning and developmental disabilities need daily trainings for social skills. However, such daily training is not provided occasionally because it requires interactive helps from therapists. In this paper, we propose a digital dollhouse that extended the traditional psychological play therapy equipped with digital sensors and computer graphics. This device aimed at raising especially the speaking and hearing skills also in communication even if the superintendent of training is not a therapist. We have developed proposed digital play therapy device. Based on the device, we discussed the usefulness of the device with the therapist, and the policy and metrics for the evaluation of the functionalities that are expected for the skill's training.

　View Summary

We propose the notion of an emotional cyborg as a new application proposal in the human-agent interaction (HAI) field. We summarize what kind of human processes maintain emotional labor and how such kind of social labor is supported by HAI technologies. We implemented AgencyGlass, a prototype application, as a tool for realizing an emotional cyborg. The device is attached on a user's face and displays the user's eye gestures. The authors implemented a prototype application for supporting emotional labor with AgencyGlass and presented this as a video. The authors analyzed reactions from media and online feedback on the prototype and illustrate the future of HAI applications.

　View Summary

近年の人工知能の技術の発展により、チェスや将棋等の完全情報ゲームでは人工知能が人間のプロを相手に勝利するようになった。一方で、不完全情報ゲームについての研究は多くはない。そこでコミュニケーションゲーム“人狼”に着目し、人工知能が目指すべき新たな目標として設定する。本研究ではこのゲーム内で使用される主な言葉をプロトコル化し、各エージェントがそのプロトコルで会話をすることでゲームが進行される。過去の会話内容やプレイヤー数等を環境とし、発言内容や能力者の行動等の戦略をQ学習により学習させ、最適戦略を解析する。

　View Summary

Our daily household activities are supported by many complicated home appliances whose functions are difficult to learn. In order to clearly explain the functions of home appliances to users, we design attachable agential triggers to render home appliances as explanatory agents. We detail how our application helps explain the use of home appliances to users. Our proposed robotic arms are easier to use than previously used attachable arms in order to point to a home appliance.

　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

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.
