Application Research Of Augmented Reality Technology In Automobile Maintenance Environment

Through researching multimodal interaction in the augmented reality,constructing the augmented reality system structural model,selecting of HoloLens as development object,this topic design automotive maintenance support system.This topic firstly introduces the research status of augmented reality technology,multi-modal interaction technology and automobile autonomous maintenance technology,and analyzes the advantages and disadvantages of these three technologies.Second,this topic researches the theory of multi-modal through the type of multi-modal information presentation and the characteristics of multi-modal interaction,put forward multi-modal integration method to reduce the user cognitive resource competition.This topic studies the display,registration,and interaction technology of augmented reality system,and according to the main characteristics of each to select corresponding usage scenarios.Finally,based on the core clue of "task" as the interaction,the idea of "time" between modes as the link,it builds the multi-modal augmented reality interaction model.Through the analysis of the character description,maintenance scenarios user and user behavior analysis to establish a user model,this topic analysis car owner requirement in the field of autonomous maintenance,and build the information architecture of system.This topic designs experiments to test users vision allocation mechanism under the augmented reality,records user eye movement data in the process of experiment,analysis the data of annotation frequency and the data of percentage dwell time,and put forward the principle of interface layout under the augmented reality.Finally,the automobile maintenance technical manual is selected as the case,and it completed vehicle maintenance auxiliary system by designing the information architecture and interactive mode.This topic presents a method to construct multi-modal augmented reality model for task,which provides reference for the interaction design of augmented reality technology in other fields.This topic analysis the influence of augmented reality on users' vision allocation mechanism by eye movement data,which is applicable to the design of other interface information layout.
