Ubiquitous computing introduces new constraints on the way we build interactive systems. Traditionally centralized, user interfaces (UI) can be distributed across a dynamic set of heterogeneous devices. In this article, we examine these new kinds of UIs, named plastic UIs, from a software engineering perspective. They are dynamic adaptable distributed software, and they able to deal with device heterogeneity at multiple levels of abstraction. However, the generic solutions from distributed software do not take into account the specificity of human-computer interaction. To address these limitations, we propose Ethylene, a conceptual and technical framework to develop UIs for ubiquitous computing. Our solution is based on the integration of model driven engineering with a particular combination of component and service oriented approaches, as weel as an original way to overcome the heterogeneity of communication models between components. |
