This article presents a rule–based agent mechanism as the kernel of a ubiquitous end–user, UI–independent programming system. The underlying goal of our work is to allow end–users to control and program their environments in a uniform, application–independent way. The heterogeneity of environments, users and programming skills, as well as the coexistence of(More)
Ambient Intelligence scenarios describe situations in which multitude of devices and agents live together. In this kind of scenarios is frequent to see the appearance of conflicts when modifying the state of a device as for example a lamp. Those problems are not as much of sharing of resources as of conflict of orders coming from different agents. This(More)
This paper presents a proposal of a context-based architecture to achieve the required synergy among the ubiquitous computing devices of an intelligent environment. These devices produce context information that models the behaviour of the environment. This context information is the glue among the devices and the context-aware applications. The generated(More)
BACKGROUND Frailty is a health condition related to aging and dependence. A reduction in or delay of the frailty state can improve the quality of life of the elderly. However, providing frailty assessments can be difficult because many factors must be taken into account. Usually, measurement of these factors is performed in a noncentralized manner.(More)
The IST Advisory Group (ISTAG) of the European Union had a vision of "Ambient Intelligence" (AmI) in 1999. It refers to " an exciting new paradigm of information technology, in which people are empowered through a digital environment that is aware of their presence and context sensitive, adaptive and responsive to their needs, habits, gestures and emotions(More)
In this paper we present the interpretation and generation processes of a spoken dialogue interface for intelligent environments. The interface is automatically created for each specific environment and the interpretation and generation vary depending on the environment and its context. These processes rely on a dialogue tree structure. Several modules(More)
In this paper we present a plug and play dialogue system for smart environments. The environment description and its state are stored on a domain ontology. This ontology is formed by entities that represent real world contextual information and abstract concepts. This information is complemented with linguistic parts that allow to automatically create a(More)
This paper analyses the requirements of automation and adaptation in the so called perceptive environments. These environments are places with the ability of perceiving the context through sensors and other mechanisms. Focusing on personal/home environments, we present a first approach and prototype to semi-automatic adaptation of Perceptive Environments(More)
Intelligent environments are ubiquitous computing systems that react to and interact with their inhabitants. They adapt to their necessities, assisting them in their every day life. We present a real intelligent environment that supports spoken interaction with its users. The spoken dialogue interface is automatically created according to the environment(More)
This article presents a proposal for managing privacy in pervasive environments. These environments are capable of sensing personal information anywhere and at anytime. This implies a risk to privacy that might not be assumed if a clear and trustable privacy management model is not provided. However, since this kind of environments posses a set of highly(More)
