Tai Hang Wang, Peng Jun Zheng · Applied Mechanics and Materials · 2014
Usability is a key indicator in the evaluation of Human-Machine Interface (HMI). ECDIS has a typical HMI for e-Navigation system. In order to improve the usability of ECDIS HMI, it is necessary to carry out usability evaluation. This paper investigated the time spent in executing typical navigation operations using two common designs, which are based on single document and dialog box. The accuracy of the theoretical prediction was verified against actual test results, and the efficiency of the two design schemes was compared. The research results can provide scientific guidance to improve the usability of ECDIS and design of HMI.
