Developing a user experience evaluation method for serious games and learning effects using pulse waves and eyeblinks

为了评估严肃游戏的学习效果，有必要建立用户体验的评估方法，如游戏的乐趣和现实感等。本研究探讨了生物信号（如脉冲波）和按钮操作行为是否可以作为用户体验的客观指标。结果表明，脉冲波Lyapunov指数和按键操作频率可作为玩家心理状态和操作行为的有效指标，可用于开发用户体验评价方法。

In order to evaluate the learning effects of serious games, there is a need to establish evaluation methods of user experience, such as enjoyment and the sense of reality of the game, among others. This study investigated whether biological signals, such as pulse waves, and button operating behaviors might be useful as objective indicators of user experience. The results indicated the Lyapunov exponent of pulse waves and the frequency of button operation could be effective indicators of psychological states and operating behaviors of players, which might be applied to developing user experience evaluation methods.
