Designing interactive systems in context: From prototype to deployment

Abstract

The possibility of communicating with the (in) direct environment using other devices and observing that same environment allow us to develop ambient intelligent applications which have knowledge of the environment and of the use of these applications. Despite the support for software development for this kind of application, some gaps still exist, making the creation of consistent, usable user interfaces more difficult. This paper discusses a technique that can be integrated into existing models and architectures and that supports the interface designer in making consistent context-sensitive user interfaces. We present an architecture and methodology that allows context information to be used at two different levels - dialogue and interdialogue levels - and ensures that the consistency of the interface is always maintained in the event of context changes during use of the software.
