System for preventing loss of replay desire in games by guiding the user to voluntary leaving from and returning to the game sessions

We have conducted a research on the time-loss experience during game play. From the study, we propose system design for preventing loss of replay desire in games by guiding voluntary leave. Experiments have shown the effectiveness of the proposed system. In the first step of this study, we have conducted a preliminary experiment for finding whether increasing cognitive workload can guide voluntary leave. The results indicated that adjusting difficulty level by modifications to the appearances of the game objects makes a difference in the cognitive workload.
