　View Summary

Bullying is a serious problem, especially at elementary schools and junior high schools, and occurs all over the world with some variations. As a countermeasure against bullying, many interventions and preventive programs have been proposed (e.g., counseling, dispatch of advisers, group work, suspension orders) and there have been many investigations presenting analyses of bullying along with intervention and prevention strategies. However, numerous samples and long times are required for the analysis of strategies in the real world. We believe that simulations of bullying and countermeasures are effective in providing quick and easy analysis. In this investigation, 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 called the "conforming strategy" to simulate bullying caused by conforming behavior of students. Student agents who implement the conforming strategy watch the human relationships around them and update their own imagined relationships. They then conform to the behavior of other students to achieve better social standing or to maintain their position on the basis of simulation results based on their own imagined relationships. The results of the experiments show that the conforming strategy increases the probability of bullying and the number of victims, and that conforming behavior increases the probability of bullying in the real world. We also describe a situation in which teachers underestimate or cannot perceive bullying when it occurs, and many teachers underestimate or cannot perceive bullying in the real world. Overall, we show that socion theory has sufficient expressiveness to be used as a foundation for bullying simulation. (C) 2016 Wiley Periodicals, Inc.

　View Summary

技術の発達によって機器の機能が増加している．増加した機能をユーザに分かりやすく伝える手法として，擬人化エージェントを用いた機能説明が提案されてきた．本研究では擬人化エージェントを実世界に拡張させる演出を用いて，複合機（Multi-Function Printer，MFP）の操作説明を行い，人間のインタラクションがどのように変化するか検証した．検証結果として，スクリーン上のエージェントの説明を実世界に拡張することにより，その後のユーザの操作時間が有意に短くなることを確認した．また，ユーザの発話量が有意に増加すること，説明後に学習への興味が向上することが評価結果から示唆された．

プロジェクタロボットを用いた運転支援システムにおけるエージェントの振る舞いの研究

堀元 見, 長谷川 孔明, 大澤 博隆, 今井 倫太

第78回全国大会講演論文集 2016 ( 1 ) 223 - 224 2016.03

　View Summary

本研究では、運転支援システムにおけるエージェントの振る舞いを扱う。従来のカーナビゲーションシステムのような単調で一方的な情報提示ではなく、運転手の視線や発言、および周囲の状況に応じた情報提示を行うシステムを作成し、このようなシステムの中で、エージェントのどのような振る舞いのが必要なのかを探る。運転手がエージェントと快適なインタラクションを行うためには、運転手の動きに対する反応の速さが不可欠である。本研究では、速い反応性を実現するためにプロジェクタロボットを用いた。プロジェクタロボットは、半球状のスクリーンに内部のプロジェクタから顔の画像を投影するロボットであり、動かすためにモータの動きを必要としない。したがって従来のロボットよりも速い反応を実現することが容易である。このような速い反応を活かしたインタラクションのための振る舞いを実装し、その効果について研究した。

　View Summary

In this study, we specify the design of an artificial intelligence (AI) player for a communication game called “Are You a Werewolf?” (AI Wolf). We present the Werewolf game as a standard game problem in the AI field. It is similar to game problems such as Chess, Shogi, Go, and Poker. The Werewolf game is a communication game that requires several AI technologies such as multi-agent coordination, intentional reading, and understanding of the theory of mind. Analyzing and solving the Werewolf game as a standard problem will provide useful results for our research field and its applications. Similar to the RoboCup project, the goal of this project is to determine new themes while creating a communicative AI player that can play the Werewolf game with humans. As an initial step, we designed a platform to develop a game-playing AI for a compe tition. First, we discuss the essential factors in Werewolf with reference to other studies. We then develop a platform for an AI game competition that uses simpli fied rules to support the development of AIs that can play Werewolf. The paper reports the process and analysis of the results of the competition.

　View Summary

A demand response method that does not inconvenience consumer lifestyles is expected to reduce carbon dioxide emissions and ensure power supply stability. In general, electric power conservation is motivated by monetary incentives or environmental concerns such as carbon dioxide emissions reductions and power failure probabilities. In this study, methods that induce consumers' power conservation actions were developed by presenting anthropomorphized/visualized information. This study involved improving experimental interfaces involving methods that closely replicate the actual way in which electric appliances are used in consumers' daily lives. Moreover, a small community model such as a micro grid was built to calculate the total amount of consumption power and CO2 emissions of each electric appliance. The experiment involved twenty participants to test power saving behaviors by using the developed interface. The experimental results indicated that the method of presenting visualized information strongly induced users' electric power saving behaviors when compared with other methods.
