The Business Application Research On The Basis Of OBD Data Interaction Visualization

This subject research comes from software engineering project of Internet enterprise.It takes product of the first generation “Having a Car in the Same City” as the research target.In the project,I found that the design and application of the OBD data interaction visualization is commonly short of a kind of scientific researching spirit.According to analyzing OBD data of “Having a Car in the Same City” and its interface of interaction visualization,I found several problems: the narrow range of the OBD data application;the design of OBD data interaction visualization ignores the car owners' requirement of the scene;the interface of OBD data interaction visualization lacks a good visual experience.The subject will provide solutions to solve these three problems and redesign OBD data interaction visualization.This subject adopts the method of interdisciplinary thinking to analyze downstream application of cars.By making use of “Matrix Method”,I picked out OBD data as the most valuable application of automobile downstream fields,which refers to location service.From the three space dimensions of pavement behavior,traffic condition and low-level environment,I explored the OBD data demand of owner in the location service.At last I confirmed the weather and traffic service as the new expanding direction of OBD data application.The owner's use of OBD data is mainly divided into driving scene and parking scene.In the driving scene,the owner requires to access the OBD traveling data quickly and accurately,while in the parking scene,the owner is more interested in the traveling record and vehicle fault detection.According to exploring the qualitative and quantitative demand of owner,the interface design of OBD data interaction visualization should make sure that the data are easy to learn and read,so as to promote the reading efficiency of the owner.As for thinking and research of the above three questions,I adopted many data visualization methods,including “Quasi-physical Reflecting Method”,“Direct Display Method”,“Icon Method”,“Geometry Display Method” and “Micro Dynamic Method” to redesign the interface of OBD data interaction visualization of the original “Having a Car in the Same City”.The aim of this subject research is engaged in providing a set of business application plan on the basis of OBD data interaction visualization to the enterprises offering OBD data service,which has a certain value reference for the related enterprises.
