摘要:

针对传统基于兴趣区的可视化方法在分析飞行员眼动数据过程中无法关注细节的问题,提出了一种基于用户自定义兴趣区的眼动数据可视分析方法。首先,根据具体的分析任务,引入对任务背景图像的自我划分和定义;然后,在此基础上,结合多种辅助视图和交互手段,设计并实现了面向飞行员培训的眼动数据可视分析系统,帮助分析人员分析不同的飞行员之间的眼动差异,最后通过案例分析,证明了可视分析方法的有效性和分析系统的实用性。实验结果表明,较传统方法来说,所提方法增加了分析人员在分析过程中的主动性,在整体和局部方面,支持分析人员对任务背景进行细节的探索,增加了分析人员分析数据的多角度性,让分析人员能够结合整体发现飞行学员在训练过程中认知困难的部分,进而制定更有针对性、更有效的训练课程。

Abstract:

Focused on the issue that the traditional interest area based visualization method can not pay attention to the details in the process of analyzing pilot eye movement data, a visual analysis method of eye movement data based on user-defined interest area was proposed. Firstly, according to the specific analysis task, the self-divison and self-definition of the background image of the task were introduced. Then, multiple auxiliary views and interactive approaches were combined, and an eye movement data visual analysis system for pilot training was designed and implemented to help analysts analyze the difference of eye movement between different pilots. Finally, through case analysis, the effectiveness of the visual analysis method and the practicability of the analysis system were proved. The experimental results show that compared with the traditional method, in the proposed method, the analysts' initiative in the analysis process is increased. The analysts are allowed to explore the local details of the task background in both global and local aspects, making the analysts' analyze the data in multi-angle; the analysts are allowed find the flight students' cognitive difficulties in the training process as a whole, so as to develop more targeted and more effective training courses.
