Résumé:
Ubiquitous computing has gained momentum over
the last years with the expansion of mobile devices. One area of
pervasive computing is context-aware systems which are
applications designed to react to the constant changes in the
environment. This paper presents a context aware platform
that handles context acquiring, processing and service
provisioning management. The platform alleviates the process
of high level application development and sets a common
ground for building context-aware applications and services.
The context-based platform objective is to support mobile
users with personalized services. It offers sophisticated
mechanisms in matching the mobile user’s preferences with
services that are enabled at the visited location, and provides
them in adaptive manner to the user.
As a proof of concept, we present a case study on tourism
where tourists are provided with services and information of
interest based on their location and time. An application for etourism is deployed on top of the platform to assist tourists
during their travels by providing them with context sensitive
services. The user preferences, the current time, and the user
current location are incorporated in the proactive formulation
of suggestions on the tourist mobile devices about nearby
points of interests (e.g. museums, restaurants….).
