Semantic Rendering based on Information Hierarchy for Urban Navigation

PP: 493-504
Divya Udayan J, HyungSeok Kim, Jee-In Kim, Keetae Kim,
City street environments are highly populated with 3D building data and associated information. Therefore, a suitable data representation scheme is needed for effectively representing relevant information to an urban navigator. The focus of this paper is to propose a design methodology for providing users with just adequate information that helps them to satisfy their purpose of visiting a particular building in a city street. In addition, we suggest a mechanism that renders the requisite information with selective levels of detail by emphasizing the regions of interest and diminishing the details of less important regions, depending on the users intention. Preliminary tests of the proposed data scheme on a set of real street building data and its evaluations show the feasibility of our approach to extend to large scale mobile applications.
