Ergonomic evaluation of portable videogame software

In this study, the authors evaluated the psychophysiological effects of video games on users. Although video games affect users in various ways, this study focused on the shortterm and direct effects. In an experiment, subjects played five kinds of video games on portable game machines for fifteen minutes. While each subject played a game, the authors measured the potential skin reaction during game play and profiled the subject’s mood states and stress markers before and after he or she played. The authors examined the differences between the various games, the players’ skills, and the information to play the game. Author
