任务绩效数据和主观评估数据被广泛用作人机交互（HCI）领域的可用性度量。最近，生理学也被探索作为评估可用性的指标。然而，尚不清楚生理测量与传统可用性评估测量有何关系。在本文中，我们研究了三种数据之间的关系：任务表现、主观评估和生理测量。我们发现了生理数据与视频游戏中的任务表现数据相关的证据：随着任务表现水平的降低，标准化皮肤电反应（GSR）增加。此外，生理数据反映在评估压力水平的主观报告中。该研究为建立一种新的可用性方法迈出了第一步，利用生理学作为传统人机交互评估的补充措施。
Task performance data and subjective assessment data are widely used as usability measures in the human-computer interaction (HCI) field. Recently, physiology has also been explored as a metric for evaluating usability. However, it is not clear how physiological measures relate to traditional usability evaluation measures. In this paper, we investigated the relationships among three kinds of data: task performance, subjective assessment and physiological measures. We found evidence that physiological data correlate with task performance data in a video game: with a decrease of the task performance level, the normalized galvanic skin response (GSR) increases. In addition, physiological data are mirrored in subjective reports assessing stress level. The research provides an initial step toward establishing a new usability method using physiology as a complementary measure for traditional HCI evaluation.
