Dandelion: Decoupled Distributed User Interfaces in the HI3 Ambient Intelligence Platform

Ambient Intelligence and Ubiquitous Computing systems must deal with a wide variety of environments, users and devices. Designing and implementing their interaction systems is quite a complicated task because it is difficult to know in advance the conditions in which the system will be run. This article presents Dandelion, a framework that uses a model-driven approach to support the development of user interfaces for UC and AmI systems by defining a series of high-level declarative models. It decouples the application logic from the interaction elements, which can be physically distributed throughout the environment, and even changed dynamically.
