为了建立一个个性化的电子学习系统，能够根据学生的认知努力和效率提供自适应的学习内容，重要的是要开发一个结构，可以帮助测量感知的心理状态，如压力和认知负荷。该结构必须能够量化、计算机化和自动化。我们的研究探讨了如何使用鼠标和键盘动态分析来检测认知压力，这种压力是由高心算需求和时间压力引起的，而不使用侵入性和昂贵的设备。研究发现，当任务需求增加时，任务错误、任务持续时间、被动尝试、压力感知和鼠标空闲持续时间增加，而鼠标速度、鼠标左键点击和按键速度下降。任务需求和时间压力对鼠标和击键行为的显著影响表明，来自这些输入设备的压力评估可能对设计自适应电子学习系统有用。
To build a personalized e-learning system that can deliver adaptive learning content based on student’s cognitive effort and efficiency, it is important to develop a construct that can help measuring perceived mental state, such as stress and cognitive load. The construct must be able to be quantified, computerized and automated. Our research investigates how mouse and keyboard dynamics analyses could be used to detect cognitive stress, which is induced by high mental arithmetic demand with time pressure, without using intrusive and expensive equipment. The research findings suggest that when task demand increased, task error, task duration, passive attempt, stress perception and mouse idle duration may increase, while mouse speed, left mouse click and keystroke speed decreased. The significant effects of task demand and time pressure on mouse and keystroke behaviours suggest that stress evaluation from these input devices is potentially useful for designing an adaptive e-learning system.
