Research On Interface Design Of Vehicle HUD Safety Information Based On Context Awareness

Head-up display(HUD),as a new type of driving assistance system,can sense various situations through vehicle sensors and adaptively push safety information to alert drivers of potential dangerous situations in advance,thereby effectively improving driving safety.However,driving scenarios have real-time dynamics and multi-dimensional complexity.A single scenario may trigger multiple active interactive information.The appearance of safety prompts with technical common icons refers to multiple interactive content phenomena,resulting in the system's conceptual model and the user's mental model.Certain differences,lack of accuracy and priority of information push will cause users to fail to capture the key information prompts of the current situation in time,resulting in irrational attention resource allocation and cognitive distraction of the user's visual channel,increasing the occurrence of situated cognitive errors Probability.Therefore,this paper combines human factors ergonomics and design methods,based on the theoretical basis of the Context-Awareness information transmission relationship and law in dynamic and complex driving scenarios,and takes the actual driving information needs of users as the driving force to clarify the type of adaptive safety prompt information Weights,explore active interaction methods that can enhance driving situation awareness,and HUD-assisted driving man-machine interaction interfaces that conform to the driver's cognitive laws.First of all,in the theoretical research part,we conducted a theoretical study on the Context Awareness of computer systems and the process of human situated cognition.From the three elements of user context,vehicle context and environmental context interaction,we established a human-machine-circle-based driving context information communication relationship model.By deconstructing and analyzing the information classification,priority,content,form and other aspects of the on-board HUD human-machine interface design information,it summarizes the principles of human-computer interaction design that should be followed by the assistant driving safety system interface,and proposes User-centric assistance Driving HUD human-computer interaction interface design process based on Context.Secondly,in the design practice part,through user research to integrate and transform various driving situation information needs,a hierarchical HUD safety prompt information model was constructed,and the information weight was determined accordingly,and HUD information organization and system interaction were completed.Adaptivestrategy,interface visual design and application.Finally,the appraisal method combining subjective and objective is used to verify the usability of interface design from three aspects: user cognitive performance,risk response ability and system experience satisfaction.The results of the study show that the visual design based on the integration of information organization and similar functions based on Context Awareness types has better cognitive performance;When faced with complex driving scenarios,multiple active interactive information displays,with adaptive safety prioritized Prompt the information interaction system has a higher ability to react to danger;The HUD information system built on the user center has a higher user satisfaction and a better driving experience.This paper has 42 pictures,17 tables,and 112 references.
