Research On Optimization Of Vehicle HUD Interface Design Based On Visual Cognitive Load

With the continuous development of optical imaging technology and in-vehicle intelligent systems,mass production of on-board HUD has become possible.Since the current technology is still not mature,the vehicle HUD interface can only be displayed in a small range,but the current display range is in the driver's core gaze area,and the future development will continue on this basis,so the research on the vehicle HUD in the background is of great value.The emergence of vehicle HUD has made the integration of vehicle information and external scenes,which has increased the visual cognitive load of the driver during the driving process.Therefore,the paper is based on the visual cognitive load,which studies the cognitive resources when the driver uses the vehicle HUD,and saves the visual cognitive resources while completing the core tasks in the specific scene.This paper firstly reviews the research on visual cognitive load theory and vehicle HUD interface,and combines the results of studying the visual cognitive load of vehicle HUD interface and interface elements,which lead to the research method of design elements;then,the research on the elements of vehicle HUD interface is carried out from user research and experiment,by means of which the visual cognitive load of each element is discussed through the experimental data such as questionnaire data,interview results,reaction time and accuracy;On the basis of user research and experiment,this paper analyzes the design principles of vehicle HUD interface based on visual cognitive load from three aspects: structure layer,frame layer and presentation layer.Finally,under the guidance of the design principles,this paper designs the vehicle HUD interface to reduce the visual cognitive load of the driver when using the vehicle HUD interface.
