Browsing Semantics in Context-Aware Mobile Hypermedia

Abstract

Mobile hypermedia applications combine the well-known advantages of the navigational paradigm of the Web with the capabilities of location-aware software. However, there are some subtleties to integrate them synergistically. In this paper we analyze different aspects related with navigation semantics in mobile hypermedia; in particular we discuss the problems which arise in the use of the familiar backward and forward operations when physical navigation in the real world is involved. Using a motivating example, we present a simple model to handle physical and digital navigation in a cohesive way. We also describe a modular implementation of our ideas in an architecture which support context-aware services.
