自动压力检测对于开发自适应电子学习系统非常重要。经验证据表明，与生理测量和面部表情识别相比，鼠标动力学和键盘动力学分析在用户行为建模和情绪检测方面都可以有效，而且它们的成本要低得多，并且被认为是非侵入性的。本文研究了鼠标动力学和键盘动力学如何受到情绪压力的影响，特别是由时间压力、文本长度和语言熟悉度引起的压力。我们的研究结果表明，较长的文本和不熟悉的语言会增加用户的压力感知。一旦用户失去动力，诸如长时间打字任务之类的高要求工作可能会导致异常行为。语言熟悉程度主要影响键盘行为，但文本长度会影响鼠标行为。这表明通过检测键盘和鼠标输入的学习者情绪压力来开发自适应电子学习系统具有良好的潜力。
Automated stress detection is important in developing adaptive e-learning systems. Empirical evidence suggests that mouse dynamics and keyboard dynamics analyses can be both effective in user behaviour modelling as well as emotion detection compared to physiological measures and facial expression recognitions, and yet they are far less expensive and considered non-intrusive. This paper investigates how mouse dynamics and keyboard dynamics can be affected by emotional stress, particularly stress induced by time pressure, text length and language familiarity. Our research findings show that longer text and unfamiliar language raise users' stress perceptions. Demanding job such as long typing task could result in anomalous behaviours once the users have lost motivation. Language familiarity mainly affects keyboard behaviour but text length change mouse behaviour. This shows that there is a good potential of developing an adaptive e-learning system by detecting learners' emotional stress from keyboard and mouse input.
