Information Layout And Color Adaptive Design Of HUD For Civil Aviation Aircraft

With the rapid development of aerospace technology in recent years,Head-up displays have been widely used in civil aviation aircraft,and gradually become the main flight information display interface of modern aircraft.The HUD interface play a vital role in the flight process,and it can help pilots get information faster and more convenient.At present,the layout of information displayed on the HUD interface and the presentation single-color mode are contrary to human cognitive habits.They pose a threat to the stable and efficient implementation of complex flight tasks.Firstly,this paper analyzes the information composition of the human-computer interface and several typical mission environment of the aviation aircraft,studies the existing information of the aircraft HUD and the information needed in specific task environment is screened and classified.Secondly,paper summarizes the HUD interface of the aircraft,including its development and principle,the design of interface layout is carried out in combination with the design principles of HUD interface in avionics system,as well as the coding design of information under the typical task environment is completed,and the improved information design of HUD interface is completed.In color adaptive system design,this paper first calculates the best matching relationship between the main color of the HUD interface and the background main color through the study of the color design theory including the relationship between the three elements of color and the visual cognition,the color coding of the visual perception layer,and so on.Secondly,the main color phase of complex environment is extracted from the whole,the environmental significant area and the color stratification three angles,including the overall color simplification,the selective color simplification,and the hierarchical clustering color simplification.The matching relationship between the HUD interface main color and the background color of the interface,we get the adaptive result of the main hue of the HUD interface under the background environment changes.Lastly,the method of eye movement research is used to do the exploration and verification of banground main-color extraction.Firstly,by comparing the reaction time between the single green display interface of the existing HUD and the HUD interface proposed in this paper,it is found that the human eye has a better recognition of the main color adaptive plan.The contrast study of the HUD interface on the main color phase with the interface on the banground shows that the main color extraction method based on color stratification is most close to the real background environment,and completes the research on the best background environment of the HUD interface adaptive system.Through the layout of the HUD interface and the interface main-color adaptive study,this paper provides a new idea of aircraft HUD interface improvement.From the perspective of design,it improves the layout and color of the aircraft HUD interface information,reduces the difficult of cognition in the HUD interface information reading,and improves the efficiency of the aircraft on the aircraft.
