Systematic Development of Physical Hypermedia Applications

Abstract

In this paper we present a model-based approach for the development of physical hypermedia applications, i.e. those mobile (Web) applications in which physical and digital objects are related and explored using the hypermedia paradigm. We describe an extension of the Object-Oriented Hypermedia Design Method (OOHDM) and present an improvement of the popular Model-View-Controller (MVC) metaphor to incorporate the concept of located object; we illustrate the idea with a framework implementation using Jakarta Struts. We first review the state of the art of this kind of software systems, stressing the need of a systematic design and implementation approach; we briefly present a light extension to the OOHDM design approach, incorporating physical objects and “walkable” links. We next present a Web application framework for deploying physical hypermedia software and show an example of use. We evaluate our approach and finally we discuss some further work we are pursuing
