Research On Visual Elements Optimization Design Of Engineering Vehicle Interface Based On Cognitive Theory

With the development of artificial intelligence and computer technology,digital display interface gradually replaces traditional interface and is widely used in various fields.Engineering vehicle is an essential engineering equipment for infrastructure projects.The cab display interface is also derived from traditional button knob to integrated digital interface.When the rich interface information is displayed on limited display screen,how to scientifically present interface information and visual elements and allocate user cognitive resources reasonably becomes the key and difficult point of interface design.Based on the school-enterprise cooperation project,this paper takes the display interface of road roller as an example.From the perspective of cognition,the paper studies the optimization design of the visual elements of the display interface of road roller in view of the existing problems in the design of visual elements of the interface of road roller.Firstly,the paper expounds the Cognitive Theory,its core viewpoints and research methods through literature research,and then studies visual cognition from three aspects: visual cognitive process,visual cognitive mechanism and visual cognitive characteristics;Secondly,taking the roller display interface as an example,the paper analyzes the characteristics and functions of the interface,and summarizes the visual elements such as icon,color,control,layout,navigation and interaction of the roller interface;Then,through questionnaire survey,user interview and target user portrait,the author conducts user investigation on roller driver,constructs user cognitive model of visual elements of roller display interface,and summarizes the cognitive requirements of road roller drivers for interface visual elements in different cognitive stages,and puts forward the design principles and optimization design objectives of the visual elements of roller interface;Finally,the important information and visual elements of roller interface are extracted by analytic hierarchy process,and the optimization design is carried out according to the existing problems.The experimental research on the home page interface before and after optimization is carried out by eye tracking technology,and the effectiveness of the optimization of visual elements of home page interface is verified;On this basis,according to the previous design principles and optimization design objectives,the visual elements of the overall interface of the roller are analyzed and optimized.Through subjective evaluation,it is proved that the satisfaction of the optimized interface has been significantly improved.The overall research ideas and contents provide a certain reference for the optimization design and evaluation of roller and other engineering vehicle interface and its visual elements.There are 42 pictures,33 tables and 100 references.
