Research On Interface Optimization Of High-speed Train Driving Display Based On Graphic Features And Cognitive Coupling

With the improvement of the degree of informatization,digital interfaces have been widely used in complex and large-scale control systems of aircraft,ships and trains.As an important digital information encoding method,the different matching forms of graphics with features such as color,shape,and background color will affect the user’s operational performance and further affect operational safety.Aiming at the high-speed train driving display interface,this paper studies the coupling relationship between interface graphic features and cognition,aiming to fit the natural cognitive attributes of human beings.Carry out a coupled human factor experiment on the characteristics of graphic symbols in the cockpit human-machine interface through typical identification task requirements,collect response time and identification accuracy,and analyze the matching relationship between graphic symbols and colors,shape features,types,and background colors.The influence of,so as to provide guidance for the optimization of digital interface information design,the specific content is as follows:(1)Investigate and analyze the layout,functional areas and information coding of the DMI and HMI interfaces of the CR400 AF high-speed train driving display,and sort out the information coding methods of text,graphics and colors in the main functional areas of the interface.(2)To sort out the existing researches on information cognition of digital interface,design the coupling experiment of graphic cognition of high-speed train driving interface based on the relevant experimental paradigm,and complete the data collection.(3)Use the Friedman test to analyze the experimental data,analyze the recognition efficiency of graphics and color matching methods under different background colors,and obtain the cognitive coupling relationship between graphics and colors;analyze the recognition efficiency of graphics and shape feature matching methods under different background colors,and obtain Cognitive coupling relationship of graphic shape features;analyze the recognition efficiency of graphics under different background colors,and obtain the cognitive coupling relationship of graphics background color;analyze the recognition efficiency of graphics and type matching methods,and obtain the cognitive coupling relationship of graphic types.(4)Discuss the experimental conclusions in combination with the existing research,and based on the conclusions of the coupling relationship between graphics and cognition,combined with the research conclusions of text and interface in related fields,put forward design suggestions for optimizing the information coding of the high-speed train driving display interface,and apply them in in design practice.This paper provides optimization suggestions and references for the information encoding method of the high-speed train driving display interface,which makes up for the lack of research on graphic encoding in this field.and availability are important.
