Research On Display Interface Design Of General Aviation Cockpit Based On Eeg Experiment

In recent years,general aviation has ushered in a peak period of development,and flight safety issues have attracted much attention.After research,it was found that the accident rate of 10,000 aircraft is on the rise,and human error has become an important factor affecting flight safety.During the flight mission,pilots mainly obtain visual information from cockpit display interface;The difficulty of interface information recognition directly affects their cognitive efficiency and flight safety.The general avionics display interface is presented graphically and displays flight status information in a centralized manner.With the progress of science and technology,and the gradual improvement of airworthiness regulations,higher requirements are put forward for the cognitive efficiency of interface information.In order to improve the cognitive efficiency of interface information,reduce the cognitive load of pilots,and improve flight safety,the cognitive load of pilots during experimental tasks was analyzed by electroencephalography（EEG）experiment.Combined with EEG experimental tasks,the cognitive load of pilots on the display interface of general aviation cockpit was studied by using event-related brain potential（ERP）technology.Firstly,the electronic display interface of aircraft cockpit is analyzed,the information elements of the interface are summarized,and the cognitive demand priority of the information elements in the interface is evaluated.Secondly,the higher priority meter shapes are deeply explored.Based on ERP component P300,the cognitive efficiency and cognitive difficulty of planar shapes and linear shapes are analyzed,so as to judge the cognitive load in experimental tasks.Finally,the experimental results show that the planar shape can improve the recognition efficiency more than the linear shape.According to the experimental conclusion and interface design principle,the cockpit display interface is improved.The evaluation system is established by using EEG experiment and subjective evaluation method,which verifies the rationality of the design scheme and provides certain reference value for the design of display interface of general aviation cockpit.
