Abstract
The cut scenes by computer graphics have become used for the video games with the advances of information technology, and then, the creators brought in a new technique so-called QTE (Quick Time Event) which makes players to put some buttons while watching the cut scenes. In this study, players’ reaction time and understanding of the context of the movies during QTE were investigated by psychological experiment using the system like QTE. The results showed that the novice players take much time to put the buttons if the interval between tasks is long and the sign of the button mark is small. In this case, all players' understanding of the cut scenes dropped slightly.
