【摘要】 眼机交互是目前人机交互技术中具有前瞻性研究价值的新方向,目前已逐步应用在虚拟现实、残疾人辅助、医疗、教育和军事等诸多领域。近年来,越来越多的设备将眼机交互的方式加入到人机对话中,发挥其直接、自然和快捷的交互特点,替代复杂繁琐的传统交互操作。但是,许多现有的眼机交互系统在界面设计上仍较为粗糙,缺少科学性、美观性和易用性,影响了实际操作中的用户体验。因此,考虑到眼机交互在将来更为广泛的应用,必须有一套成熟的设计规范以保证界面设计的可用性。本次课题致力于研究眼机交互界面控件的合理设计方法,在对眼机交互技术工作原理、眼动信号采集精度、及米达斯接触问题的探讨基础上,认为影响眼机交互界面控件使用的因素主要有控件位置、控件面积、控件间距和控件的凝视触发时间,并针对性开展了工效学的实验探究。首先,对眼机交互界面中不同区域位置和面积大小的控件触发情况的进行了实验探究,通过对20名被试的触发率和触发任务完成时间的实验数据进行整理和分析,得到了不同区域控件面积设计的推荐范围。根据控件的触发情况对于控件的位置摆放提出了最优区域、次优区域和一般区域的理论。其次,在合理的控件面积设计下,对相邻控件之间的间距的改变是否对控件的触发情况产生影响这一因素进行了实验探讨,得到了相邻控件之间间距的推荐值:控件之间的距离在75像素(视角1.084°),控件的触发效果达到最好。第三项实验是控件触发时间的合理设置范围的探究实验,实验得到的结论是:当控件的大小、间距设置合理的情况下,控件的触发时间设置的推荐范围是700到900ms之间。这些实验结论为眼机交互界面控件的面积大小的设计和区域位置的安排,以及触发时间的设置,提供了客观的理论依据。论文的最后,对眼机交互界面中控件的视觉表征设计做了相应的总结,阐述了眼机交互界面设计和交互设计的基本原则,将得到的结论应用于实际的界面中,对设计中可能遇到的问题提供参考意见,并给出了具体的眼机交互界面设计参考案例。更多还原

【Abstract】 Eye-computer interaction is a new direction with prospective research value in human-computer interaction technology.It has been gradually applied in many fields such as virtual reality,disability assistance,medical treatment,education and military.In recent years,more and more devices have added eye-computer interaction to the human-computer dialogue,giving full play to its direct,natural and fast interactive characteristics,replacing the complex and cumbersome traditional interactive operation.However,many existing eye-computer interaction systems are still relatively rough in interface design,lacking of scientific,aesthetic and ease of use,which affects the user experience in actual operation.Therefore,considering the wider application of Eye-Machine Interaction in the future,we must have a set of mature design specifications to ensure the usability of interface design.This project is devoted to the study of the reasonable design method of eye-machine interaction interface control.Based on the discussion of the working principle of eye-machine interaction technology,the accuracy of eye movement signal acquisition and the problem of Midas touch,it is considered that the main factors affecting the use of eye-machine interaction interface control are the position of control,the area of control,the distance between control and the staring trigger time of control.The experimental exploration of learning.Firstly,the triggering situation of the control in different areas and sizes in the Eye-Machine Interface was experimentally explored.By sorting out and analyzing the experimental data of triggering rate and completion time of triggering task of 20 subjects,the recommended range of area design of the control in different areas was obtained.According to the triggering situation of the control,the theory of optimal region,sub-optimal region and general region is put forward for the placement of the control.Secondly,under the reasonable control area design,whether the change of spacing between adjacent controls will affect the triggering situation of the control is discussed experimentally.The recommended space between adjacent controls is obtained:The trigger effect of the control is the best when the distance between the control arranged horizontally is 75 pixels(viewing angle is 1.084 degrees.The third experiment is the exploratory experiment of the reasonable setting range of trigger time of control.The conclusion is that when the size and spacing of control are set reasonably,the recommended setting range of trigger time of control is 700-900 ms.These experimental results provide an objective theoretical basis for the design of area,the location of eye-machine interface controls and the setting of the trigger time.At the end of the paper,the visual representation design of control in Eye-Machine Interface is summarized,and the basic principles of Eye-computer Interface design and interaction design are expounded.The conclusions are applied to the actual interface toprovide reference opinions on the problems that may be encountered in the design,and specific design reference cases are given.更多还原
