Usability evaluation of mining machinery interface based on eye movement experiment

Abstract

The paper focuses on the usability of coal machinery interface by means of eye tracking methods to build the machinery interface assessment model based on eye movement experiment. The roof bolter has been compared with two different types based on eye movement usability tests. The results are specific as follows: ① the eye movement usability index and evaluation model are designed. Heat map is used to represent complete effect and eye movement usability index and information processing efficiency are used to represent efficiency, whereas pupil size is used to represent physical satisfaction; ② to combine with the practical situation of mining machinery, the usability factors model of mining machinery interface has been built. Thereby, the design principle of mining machinery interface is summarized. Therefore, this paper preliminarily discusses the correlation between the interface usability dimensionality and eye movement index and builds the eye movement usability evaluation model which could provide the research method so as to evaluate the machinery interface base on eye movement technology.
