Current context-aware services make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context is often imperfect. In this paper, we describe an architecture that supports the building of context-aware services that assume context is imperfect and allows for the refinement of this imperfect context by mobile users in aware-environm...

Exploiting context-aware environments, where sensors scattered in a environment update presence servers to indicate the environmental changes can be used to enable new services. Such systems have become feasible both in terms of technical difficulties and their cost. A current focus in this area of research is how a context-aware system should be designed so that it reduces both the cost and co...

The proliferation of smart things and the subsequent emergence Internet Things has motivated deployment intelligent spaces that provide automated services to users. Context-awareness refers ability system be aware virtual physical environment, allowing more efficient personalization. Context modeling reasoning are two important aspects context-aware computing, since they enable representation c...

Emotion is a dynamic variable that modulates how we perceive, reason about, and interact with our environment. Recent studies have established that emotion’s influence carries to data analysis and visualization, impacting performance in ways both positive and negative. While we are still in the infancy of understanding the role emotion plays in analytical contexts, advances in physiological sen...

This paper explores the role of cues in manipulating attention with the purpose of understanding their potential value to attention aware systems design. Four dimensions of attentional processing are presented along which recent findings in the attention literature can be conceptualised: (1) Locus of control; (2) Spatial cue information; (3) Semantic cue information; (4) Timing of the cue. We s...

Context–aware systems use data obtained from various sources to adapt and provide services of interest to the user according to their needs, location or interaction with the environment. However, the use of heterogeneous sources creates a large volume of data that may differ in format, transmission speed and may be affected by environmental noise. This generates some inconsistency in the data, ...

The increasing use of personal in-car technologies has created more opportunities for driver distraction. Communication and navigational systems exact a high cognitive price for the assistance they provide to the driver. Starting from existing research in the areas of augmented reality and context-aware systems, this paper proposes a system designed to assist the driver in the primary task whil...

Aspects sometimes conflict between them in scenarios where they reify resource awareness concerns. These conflicts are the result of the scarcity of resources and the fact that, frequently, aspects are mutually oblivious. This kind of conflict can be solved by managing aspects according to the context. Obliviousness can be retained and, at the same time, specific (per situation) conflict resolu...

The provision of context-aware services in terms of the anytime/anywhere/anymedia paradigm requires the consideration of certain context information in terms of, e.g., time, location, device, and user’s preferences. These various context information will often be provided through a series of various sources being available in diverse formats and standards, e.g. device profiles, user databases, ...
