Research On The Experience Design Of In-Vehicle Infotainment System Based On Perceived Personalization

With the increasing automation of automobiles,vehicles are undergoing a gradual transformation,from functioning merely as a mobility tool to operating as a "third space".In terms of approaching non-driving related tasks,greater information and entertainment functions have been added to intelligent in-vehicle infotainment systems,providing diverse experiences for users.At the same time,these updated functions fulfill the basic requirements of users.User demand for personalized intelligent in-vehicle infotainment systems continues to increase day by day.As a result,designing a system that provides users with an effective personalized experience has gradually become a hot topic of concern in the industry.Currently,the focus of research on personalization of intelligent in-vehicle infotainment systems has shifted from technology to experience.The entire field lacks targeted and systematic methodological guidance.Theoretically,research studies that focus on the intrinsic connection between users,design elements,and personalized experiences remain scant,which has led to the misuse of personalization and the phenomenon of ineffective personalization.Perceived personalization is a subdivision of the field of personalization that focuses on the validity of personalized experiences.As a new design paradigm in user research,experience design regards "experience" as a design object.Applying perceived personalization and experience design to personalization design research can effectively limit the scope of personalization design.It should be noted that since L3-L5 intelligent cars are not commercially available on a large scale,potential users of intelligent invehicle infotainment systems lack practical experience;this is a characteristic of the field that should not be ignored in the research process.Therefore,this paper takes perceived personalization as a starting point and combines experience design’s theoretical dimensions with the forward-looking field’s research methods.The core of this research study is the personalized experience of intelligent in-vehicle infotainment systems.This paper explores the relationship between personalized experience elements in the system,and proposes corresponding design models and design strategies that provide theoretical reference for personalized experience design of related products.First,this paper utilizes the literature analysis method and summarizes existing theories of experience design and perceived personalization.It also combines the design characteristics of an intelligent in-vehicle infotainment system based on the three dimensions of perceived personalization and experience EEI model.An analysis of the personalized experience elements in intelligent in-vehicle infotainment systems was conducted to determine design connotation and research framework.Second,this study performed scenario thinking and user evaluation,through which future scenario and high-tech travel scenario were identified.The LDA topic model and questionnaires were used to construct user personas based on personalized expectations in the scenario.Moreover,expert interviews provided details regarding design elements based on personalized events in this scenario.Subsequently,a self-reporting approach was employed in this study,particularly an assessment system based on personalized impact.The objective was to reserve the perceived personalization elements and to evaluate the experience value of design elements.Personalization matching relationships between users and design elements were identified,along with the design priorities between different elements.Additionally,influencing factors of personalization experiences in intelligent in-vehicle infotainment systems were summarized.Finally,based on the above research results,a design model and a design strategy were proposed,which include the following three dimensions:personalized expectation,personalized event,and personalized impact.The strategy’s feasibility was verified through design practice.Through theoretical and experimental research,this paper proposes research dimensions applicable to intelligent in-vehicle infotainment systems and personalized experience design strategies for such systems in high-tech travel scenarios.The study provides innovative ideas and methodological references with practical significance for research in related fields.
