The notion of context has been recently recognised as a key element in the development of
context-aware information systems. Context varies according to application constraints, but …

Emerging and continuing advances in ambient systems and localization techniques have
brought novel opportunities to develop context-aware navigation services in indoor …

The range of applications in ambient information systems progressively evolves from large
to small scale environments. This is particularly the case for applications that assist humans …

Over the last decade, harnessing the commercial potential of smart mobile devices in indoor
environments has spurred interest in indoor mapping and navigation. Users experience …

Location-based mobile services have been in use, and studied, for a long time. With the
proliferation of wireless networking technologies, users are mostly interested in advanced …

With the recent progress in indoor spatial data modeling, indoor mapping and indoor
positioning technologies, several spatial information services for indoor spaces have been …

The objective of this entry is to review current spatial data models and mobile data
management techniques available for indoor spaces. In particular, the role of contextual and …

Indoor navigation is growing rapidly with widespread developments in the collection and
processing of sensor information for localisation and in routing algorithms calculating …

Location is one of the most important elements of context in ubiquitous computing. In this
paper we describe a location model, a spatial-aware communication model and an …

Looking back at early geographic information systems, it becomes obvious that technologies
nowadays are significantly different. With the emergence of spatially aware mobile …
