We present a context awareness framework to assist a Museum visitor’s learning process by providing an enriched tour experience. We adapt the information a visitor receives about an artwork based on their interests and knowledge. We show how this is achievable by implementing a system that passively and unobtrusively gathers information using physical and virtual context. We also allow the visi...

SCEL (Service Component Ensemble Language) is a new language specifically designed to rigorously model and program autonomic components and their interaction, while supporting formal reasoning on their behaviors. SCEL brings together various programming abstractions that allow one to directly represent aggregations, behaviors and knowledge according to specific policies. It also naturally suppo...

In context-aware systems, one of the main challenges is how to model context uncertainty well, since perceived context always yields uncertainty and ambiguity with consequential effect on the performance of context-aware system. To handle uncertainty in context-aware systems, firstly, we should know from where uncertainty comes. In this paper, we argue that uncertainty comes from several source...

In Europe, we observe an increasing number of people with health problems, who could theoretically receive care outside of a hospital when their condition could be properly monitored. Not being able to provide this monitoring leads to an increasing pressure on an already overcrowded hospital system and increased costs. Ubiquitous technology on top of a high-quality IT infra-structure has alread...

Determining the physical location of the users of a multi-agent system is essential if we want it to provide them with context-awareness services. A context-aware system can answer to the requests of its users in a more effective way, being able of consider the conditioners that affect them. Here we present SMAUG, a multiagent context-aware system aimed at managing the university tasks of tutor...

Context awareness in Body Sensor Networks (BSNs) has the significance of associating physiological user activity and the environment to the sensed signals of the user. The context information derived from a BSN can be used in pervasive healthcare monitoring for relating importance to events and specifically for accurate episode detection. In this paper, we address the issue of context-aware sen...

Context-awareness refers to systems that unobtrusively adapt to the environment of their users on the basis of context information, popularly known as contextaware systems. One inherent property of context information is that it possesses a certain quality, such as the certainty with which it has been determined and so on. Different aspects of this quality are represented by a set of indicators...

There are currently important barriers that hinder the access to ICT, especially for the elderly and people with disability. This paper presents the approach adopted by the Cloud4all Consortium to create the technical core of the Global Public Inclusive Infrastructure (GPII). The GPII aims at producing a real impact on achieving global access to ICT. Already in the second half of the project, t...
