Realtime User Interface Generation in Ubiquitous Environment

Imen Ismail, Faouzi Moussa

In ubiquitous and intelligent environments, the human-system interaction has become a major concern. Consequently, a new form of interaction is emerging, the ubiquitous interaction. Within this context, a system that performs at realtime and as required by the user would support the reliability and reinforce the purpose of such interaction. Adapting the information to the context of use by knowing at the right time the appropriate useful one remains the most crucial challenge to address. Up until today, there is no agreement on an ideal operating strategy for adaptive systems. However, it is recognized that adaptation strategy is a range of policies designed for the system when responding to a specific event. In the light of this, one of our key policy issues is to extract the information needed to create and update a current user model as well as his environment. A dynamic modelling approach has been described in this paper. As such, based on the currently used technology, the dynamic composition of web services, this work demonstrates how a task model will be dynamically generated, thus, providing the basis for the automatic and realtime generation of the user interface.
