ABSTRACT

Mobile devices equipped with GPS provide powerful tools for location-aware applications. Adding views to locations further augments users' perception of spaces. This work proposes a systematic approach to establish scene maps of a city with local, route, and object panoramas. The scene map is an ideal digest to access spatial information. We design comprehensive visual indexes for virtual travel and real guidance of an area based on PDAs. The extended fields of view of various panoramas enhance the understanding of spaces on small mobile devices. Densely embedded indexes from views allow free transitions and exploration in the urban area.
