Robot to Play Video Games Together

This study proposes a communication robot that plays video games together with the user to create a fun atmosphere for a daily-use robot. In recent years, the lack of conversation in daily life has become a problem, and as a solution to this problem, a dialogue robot have attracted attention as a substitute for a human and as a means of encouraging daily speech. In this study, we propose a dialogue robot that plays a video game with a user in order to produce enjoyable daily communication with the robot. The proposed method not only controls the robot’s speech, but also controls the game development by manipulating the game characters. The proposed robot enhances a user’s enjoyment by adjusting the level of game manipulation to produce a competitive match and by speaking according to the game scene. A robot that produces speech that makes a player feel positive emotions is called a friendly robot. In order to examine the effects of these robots on a user’s enjoyment, we conducted an experiment with 30 subjects in which they were subjectively evaluated by questionnaires in two types of matches: with a friendly robot and alone. The results showed that robots were more enjoyable than playing alone.
