End User Service Composition: Presenting a composition tool for end users with modular architecture and a graphical user interface

Abstract

The report focuses on a possible problem to end users do to lack of control in a rapidly growing environment of computation embedded devices, and collaborative linking of various services. Such environments are often referred to as ubiquitous or pervasive computing environment. We have looked into why this problem may occur and more importantly, how to reduce the effect it may have on end users. Our work involves the process of creating a framework that can enable end users to compose services, by connecting them in a manner that allows them to become more then it's single components. We propose an architecture that can support rapid composition, and a user interface that can perform rapid end user service composition at any time. From the time that a user finds the need to connect two or more services together to the user having set up a complete composition should be a task performed as quick as drawing a composition on a sheet of paper. We therefor propose a Graphical User Interface to support the end user, and we will in this report show how it is made and how it works. We will also present the architecture needed to support such a user interface.
