Poster Abstract: An Indoor-Outdoor Navigation Service for Subway Transportation Systems

چکیده
The proliferation of mobile computing has prompted navigation to be one of the most attractive and promising applications. Conventional designs of navigation systems mainly focus either indoor or outdoor navigation. However, people have a strong need for navigation from a large open indoor environment to an outdoor destination in real life. In this poster, we present a joint navigation system, named ioNavi. It can enable passengers to easily deploy indooroutdoor navigation service for subway transportation systems in a crowdsourcing way, without comprehensive indoor localization systems. Any self-motivated passenger records and shares its individual walking trace and associated rich set of sensor readings, from a location inside a subway station to an uncertain outdoor destination within a given range, such as one kilometer. ioNavi further extracts navigation traces from shared individual traces, each of which is not necessary to be accurate and usable. A following subsequent user achieves indoor-outdoor navigation services by tracking a recommended navigation trace.

The Great Indoors: A Data Management Frontier
Much of the research on data management for moving objects has assumed an outdoor setting in which objects move in Euclidean space (possibly constrained) or some form of spatial network and in which GPS or GPS-like positioning is assumed explicitly or implicitly. That body of research provides part of an enabling foundation for the growing Location-Based Services industry. However, we lead larg...

Nowadays, location-based services based on GPS and map data are commonly available. Since GPS does not work in buildings and map data provide geographic information only, such services are limited to outdoor scenarios. Large research effort has been carried out to explore indoor positioning and navigation systems but up to now mostly proprietary and isolated solutions have been proposed. In thi...
