　View Summary

'Are you a werewolf?' is one of the most popular communication games and is played globally. The AIWolf Project developed an agent, named 'the AIWolf,' that can play 'Areyou a werewolf?'. An AIWolf utters its thoughts using an AIWolf Protocol. As it is difficult for humans to understand the AIWolf Protocol, translation into natural language is required when human players are involved. However, the conventional method of translation uses a word-to-word method, creating the impression that the utterances have been generated by a machine. This study aimed make the utterances of AIWolf sound more human. The authors set the target that a human player would be unable to distinguish human speech from that generated by AIWolves (the Turing test). The authors define the situation as the maximum value of humanity. The output of translated AIWolf Protocol was paraphrased using data from Werewolf BBS Logs. This study considers making the utterances of AIWolf sound more human using Werewolf BBS Logs and a possibility assignment equation with fuzzy sets. In this paper, an experiment was conducted to confirm whether paraphrasing the utterances of AIWolf using Werewolf BBS Logs for human-like speech is useful or not. It was shown that the experimental method produced slightly more human-like speech than the conventional method.

　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.

Effect of Information Presentations on Consumer Emotions to Induce Power Saving Actions

　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.

E-Gaze Glasses: Simulating Natural Gazes for Blind People.

　View Summary

Gaze and eye contact are frequently in social occasions used among sighted people. Gaze is considered as a predictor of attention and engagement between interlocutors in conversations. However, gaze signals from the sighted are not accessible for the blind person in face-to-face communication. In this paper, we present functional work-in-progress prototype, E-Gaze glasses, an assistive device based on an eye tracking system. E-Gaze simulates natural gaze for blind people, especially establishing the "eye contact" between blind and sighted people to enhance their engagement in face-to-face conversations. The gaze behavior is designed based on a turn-taking model, which interprets the corresponding relationship between the conclusive gaze behavior and the interlocutors' conversation flow.

　View Summary

In this paper, we focus on the Werewolf Game. The Werewolf Game is an advanced communication-game in which winning or losing is directly linked to one's success or failure in communication. Therefore, we expect exponential developments in artificial intelligence by studying the Werewolf Game. In this current study, we propose a psychological model that considers multiple perspectives to model the play of a human such as inferring the intention of the other side. As one of the psychological models, we constructed a "one's self model" that models the role of others as viewed from their own viewpoint. In addition, to determine whether one's opinion is reliable after inferring other's intentions, we also constructed an "others model" that models the role of others as viewed from their viewpoints. Combining these models, we showed through experimentation that a combined approach achieved better results, i.e., higher win percentages.
