摘　　要：运用基于任务的KLM模型,对ECDIS人机界面的2种常见设计方案(基于单文档和基于对话框)执行特定任务所需的操作用时进行了理论预测,然后通过实际测试检验理论预测结果的准确性,进而比较这2种设计方案执行相同特定任务的效率.Usability is a key indicator to evaluate Human-machine interface （HMI）. ECDIS is a typical HMI for e-Navigation. In order to improve the usability of ECDIS HMI, it is necessary to conduct usability test and evaluation. The paper uses the method called Keystroke-level model （KLM） to investigate the time spent on executing typical navigation operations using two common design schemes, which are based on single document and dialog box. In this report, the accuracy of the theoretical prediction is tested against the actual test results, and the efficiency of the two design schemes is compared. The results are expected to provide technical insights for the usability of ECDIS and design of HMI.
