This paper describes a next generation software toolkit which provides a framework, including security and intelligibility support, for developing more powerful context-aware applications for the modern mobile environment. Modern mobile computing environments, with reasonable connectivity, processing power and sensing capabilities on portable devices provide a means of achieving truly ubiquitous context-aware computing. To application developers, the mobile environment also presents a new and unique set of challenges such as - restrictions on communication, data storage, power, etc. that vary for each device in the ecosystem and also fusing, filtering and regulating the flow of context information from various sources (sensors, online information sources, etc) bring further overheads to the context-aware application developer's task.
