Context-aware media player (CaMP): Developing context-aware applications with separation of concerns

The constant advent of powerful mobile devices has raised the potential of building novel context-aware applications. These applications let the users enjoy a better experience by sensing their context and automating tasks that would otherwise require significant user attention. This paper presents two context-aware applications, built on top of the MUSIC middleware´s context management framework. By describing the development steps, we reveal how development is facilitated via Separation of Concerns and how code reuse is enabled in terms of reusable context plug-ins. It is argued that this approach reduces the required development and maintenance effort and thus lowers the associated cost.
