Research On Data Interactive Method Based On Context Awareness For Mobile Graphics Hybrid Rendering

With the popularity of mobile devices which represented by smart phones and tablets,and the vigorous development of computer graphics and mobile Internet,the demand for 3D mobile applications with high quality is becoming more and more urgent.Compared to the PC,mobile devices have less hardware resources,which will inevitably affect the effect of mobile graphics rendering.For this reason,the research group proposed a hybrid graphics rendering mode of local and remote in mobile environment and improved the authenticity and interactivity of mobile graphics rendering by researching on the rendering method of hybrid scene.The data interactive method based on context awareness for mobile graphics hybrid rendering system is studied in this paper based on the research of the research group.In order to improve the real-time capability of hybrid rendering system by sensing user intention automatically,the theories and methods of context awareness and personalized recommendation are applied to the data interaction.In this paper,the main work and research results are as follows:(1)Construction of context-aware framework for mobile graphics applications.Analyzing the context about mobile graphics applications,a context hierarchy model of mobile graphics applications is established,and a context-aware framework and strategy which aim at mobile graphics applications are proposed by improving the existing context-aware framework,Context Toolkit.(2)Construction of the ontology model for mobile graphics applications.Adopting the context modeling method based on ontology,an ontology relation model about mobile graphics applications is built,and an ontology model based on the Web Ontology Language,or OWL for short,is established by using Protege.According to the reasoning method based on rules,a custom Jena rule base is created to implement Jena ontology reasoning.(3)Prediction of user preference based on context awareness.Regarding the 3D virtual fitting system as research object,Bayesian Network models are built by analyzing the influence factors of user preferences.To predicting user preferences,the weight of each model in the entire user preference model is calculated by using correlation coefficient method to build the final user preference model.(4)Construction of the data interactive model based on context awareness.A data interactive method for mobile graphics hybrid rendering mode is proposed by studying the main work and technology solutions of each module in detail.Finally,a web-based 3D mobile virtual fitting system is designed and developed,which integrates research results of this paper.Then we give experimental results and summarize the works have done,at the same time,point out the research work of next step.The result of the experiment shows that systems which use the method proposed by this paper can process mobile graphics data in advance by predicting user intention,improving the real-time capability and user experience.The research of this paper can make the mobile graphics technology more widely used in the field of entertainment,transportation and so on.
