Model-Based Concerns Mashups for Mobile Hypermedia

Mobile (or Physical) Hypermedia combines the navigational style typical of Web applications with the functionality of location and context-aware software. Users explore digital and physical relationships while accessing to information about their actual location, e.g. the object in front of them. Similar to “conventional” Web applications one might suffer usability problems when dealing with multiple informational concerns, but the situation gets worse because of screen size issues, the need to avoid user distraction, etc. In this paper we outline our model based approach for building mobile hypermedia applications by combining (“mashing up”) information corresponding to multiple concerns in a modular, usable way. Architectural issues are discussed and a simple example is presented together with its implementation.Laboratorio de Investigación y Formación en Informática Avanzad

Architectural and Implementation Issues for a Context-Aware Hypermedia Platform

In this paper we present the rationale and the main components of a modular and extensible architecture for building and deploying mobile hypermedia software. Using some simple archetypical examples we show how to provide context-aware assistance to the mobile user, as he explores the physical world. We also show that this kind of software systems poses strong requirements on supporting software (such as Web browsers) and we explain how to provide a modular software substrate to support these requirements. This paper shows how to use some simple concepts to develop complex context-aware systems, which are evolvable and easy to extend.Facultad de InformáticaLaboratorio de Investigación y Formación en Informática Avanzada (LIFIA

A Flexible Architecture for Context-Aware Physical Hypermedia

In this paper we present the rationale and the main components for a modular and extensible architecture for building and deploying physical hypermedia software. We show that this kind of software systems poses strong requirements on supporting software (such as Web browsers) because they involve complex context-aware navigation semantics. By using some simple archetypical examples we also show how to provide context-aware assistance to the mobile user, as he explores the physical world

Systematic Development of Physical Hypermedia Applications

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 pursuingFacultad de InformáticaLaboratorio de Investigación y Formación en Informática Avanzada (LIFIA
