Service Abstraction Model for Dynamic User Interface Presentation
This paper describes a novel approach based on the user interface presentation of unknown services within a pervasive environment dedicated to dependant people. The idea is to map the heterogeneity of the environment objects into abstracted service. At the level of the user interface, this will allow the personalization and the adaptation based on user’s requirements. Service provision has to be effective and performed according to current context particularly when focusing on people with special needs. The proposed Service Model (SM) supports the diversity of existing pervasive services and their content, the personalization and adaptation to both user and device profile, and the context-aware discovery in visited environment. The SM is composed of three main parts: Service Profile describing what a service can do, Service Interface describing how a service should be used and Service Logic Code dealing program code and internal functionalities of the service.
