Research On HUD Adaptive Interface Layout Design Of Fighter Based On Flight Mission

Under different tasks,there are differences in the interface information that pilots need to see during flight operations,each pilot observes different interface areas according to his own judgment.In order to design the HUD interface layout reasonably and reduce the research cost in the actual flight phase.This paper focuses on different flight tasks and explores the laws of HUD interface layout based on the pilot’s visual perception characteristics.Meanwhile,an adaptive design method of HUD interface layout is proposed based on flight mission and cognitive characteristics.HUD interface layout design is optimized and improved in the experimental phase to provide theoretical and experimental support for HUD layout design in actual combat.The specific research works are as follows:(1)Analyzed and summarized the theoretical basis of HUD interface layout design.This paper investigated and studied the information structure of HUD interface at present,analyzed and screened the typical flight status and tasks of fighter aircraft,and then summarized the theoretical basis of human visual perception system,interface visual perception parameters and interface visual perception characteristics from the perspective of visual perception recognition of pilots.(2)A computational model of attention distribution based on flight mission and pilot’s visual perception is proposed.Based on the mission and pilots visual perception based on HUD interface division and eye movement experiments,according to different drivers get eye movement data under different task phase distribution of attention and mental load conditions,and the effect of quantitative HUD display interface for pilots cognitive factors,combination of theoretical and experimental pilot attention distribution model is established,as the basis of adaptive layout research,provide the basis for subsequent HUD interface layout optimization design.(3)Various methods have verified the effectiveness of the attention distribution model and got an adaptive method of HUD layout and an optimized interface.The eye movement experiment method and subjective evaluation method are used to verify the effectiveness of the attention distribution model and the rationality of the optimized layout.By analyzing the relevant eye movement indicators and the results of the subjective evaluation workload verify the effectiveness of the HUD display interface’s attention distribution model.The size of the interface area is adaptively adjusted according to the pilot’s attention distribution and the comparative adaptation value is calculated in real time until the fitness value reaches the maximum value of attention distribution In order to obtain the optimized design scheme of HUD adaptive interface layout.
