Context management for end user development of context-aware applications

Mobile device context-aware features should be closely coupled to the end user demands. This is achieved by enabling end user development of context-aware applications. A context framework and a tool are presented for facilitating easy customization of context-aware features into existing mobile terminal applications. A blackboard-based context framework for mobile devices is extended with a component for handling user-defined context-action rules, and a component for activating application actions. Example cases of context-aware features customized with the implemented framework and the tool are presented, with discussion of the potential scope of end user development in mobile devices.
