摘要: Ubiquitous positioning requires services that are supplemental to the existing Global Positioning System (GPS). For spaces where GPS does not work (indoors, canyons, etc.) augmented or enhanced systems necessary. such function appropriately users must have a GPS-like experience. In essence, of supplementary trust information these deliver. order develop mimic generated by and better understand implications features changes system we believe conceptual model is Such consider several aspects user system. The be accurate, with an informative User Interface transparent (provides context background on positions how they calculated), it use verified source data, provide supports range users. this paper present essential elements for systems.
