Research On Quantitative Model Of User Experience Evaluation Of Intelligent Vehicle Information Entertainment System Based On Embodied Cognition

At present,cars have become an indispensable part of our life.With the development of intelligent network technology,vehicles with single function are gradually transformed into intelligent mobile space.User experience is to evaluate whether a car good important standards,and who is the experience of auto service main body,intelligent vehicle infotainment system as people car interactive link,play a key role,so "user-centric" user experience design principle in the intelligent vehicle infotainment system as an important design basis has always been emphasized.The selection of relevant research methods for vehicle-mounted systems is mostly conducted around designers,experts and decision makers.The actual user participation is relatively low,and the selection results and products cannot reflect the experience and feelings of the target users,which is not conducive to meeting the diversified and personalized needs of consumers.Embodied cognition emphasizes the importance of the body in the cognitive process.The theory of embodied cognition is introduced into the user experience research of intelligent vehicle infotainment system to strengthen the user’s physical participation and their interaction with the surrounding environment,which is user-centered design research.In this paper,from the Angle of cognition and intelligent vehicle infotainment system user experience to carry on the quantitative research,first of all,through the analysis of the body,the relationship between perception and cognition,related to body and intelligent vehicle infotainment system,introduced the intelligent car infotainment system body experience levels(perception layer,behavior layer,the cognitive layer),as a smart car infotainment system user experience evaluation dimensions of the source.Then,combining with users’ experience requirements for intelligent vehicle information system,user experience levels are derived,which are respectively functional experience,sensory experience,interactive experience and emotional experience.Through literature research,28 evaluation indexes were obtained,and 26 evaluation indexes were collected through semi-structured user interview,a total of 54 evaluation indexes were obtained.Among them,35 evaluation indexes were concluded by deleting irrelevant indexes and merging duplicate indexes.Then,20 evaluation indexes were selected and determined by expert scoring.Next,based on the user experience evaluation index,using the likert 5scale respectively for novice users,among users and experience the initial investigation by questionnaire,to analysis of the questionnaire design and evaluation system is reasonable,different layers of the experience of the initial survey data analysis made in the 20 indexes and select two index of consistency is not high.Through the issuance of a formal questionnaire and recycling questionnaire data,combined with principal component analysis(pca)for the index weights,build a quantitative model for intelligent vehicle infotainment system user experience,which contains three evaluation dimensions,four experience levels and 18 indexes,and index weight priority order design optimization of the corresponding measure is put forward.According to the questionnaire data of different groups,different experience index weight histogram was constructed.Finally,the quantitative model of user experience was used to evaluate the user experience of the existing intelligent vehicle information and entertainment system on the market,and the design and optimization of its interface was carried out to demonstrate the application method and effectiveness of the model.
