This paper talks about user needs rather than the details of interfaces. It covers certain kinds
of location-aware applications, plus context-aware applications in general. It is a shortened …

Location-Based Services (LBSs) utilize information about users' locations through location-
aware mobile devices to provide services, such as nearest features of interest, they request …

This paper presents a location model for location-aware and user-aware services in smart
environments. It can be dynamically organized like a tree based on geographical …

This paper describes some of the complexity that needs be captured in any location model
of an intimate environment. We take the position that a location model for such an …

In this article we propose a hybrid spatial model for indoor environments. The model
consists of hierarchically structured graphs with typed edges and nodes. The model is hybrid …

This paper presents a generic concept of location-based service as an abstraction for
supporting the association between computational resources and location. The objective is …

Location is a powerful (even ubiquitous) concept. In the case of ubiquitous computing, there
are two broad classes of needs that a knowledge of location serves: 1) location provides …

Location-based services have become an increasingly interesting research area in the last
two decades. However, in many scenarios, dealing with the most precise location …

An expressive representation for location is an important component in many applications.
However, while many location-aware applications can reason about space at the level of …

We present a map modelling toolkit that meets the special requirements of pedestrian
navigation in intelligent environments. Its central component is a graphical editor, which …
