Research On Design Method Of Interface Controls Oriented To Eye-computer Interaction

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.
