We examine the relationship between context engines and content management systems, showing by means of an example application how these should mutually interact with each other to ensure the timely delivery of relevant information. We show how a content management system can use context information to enrich its functionality and also how a general and(More)
Interaction design is a major issue for mobile information systems in terms of not only the choice of input-output channels and presentation of information, but also the application of context-awareness. To support experimentation with these factors, we have developed a platform that supports the rapid prototyping of multi-channel, multi-modal,(More)
Context-awareness has become an important consideration in the development of mobile and ubiquitous systems. While efforts have been made to develop general context models and application frameworks, it remains the case that often the notion of context supported is very restrictive and/or the representation of context is based on simple key-value pairs. As(More)
Interaction design is a major issue for mobile information systems in terms of not only the choice of in-put/output channels and presentation of information, but also the application of context-awareness. To support experimentation with these factors, we have developed platforms to support the rapid prototyping of multi-channel, multi-modal, context-aware(More)
Our demonstration is a paper-based interactive guide for visitors to the world's largest international arts festival that was developed as part of a project investigating new forms of context-aware information delivery and interaction in mobile environments. Information stored in a database is accessed from a set of interactive paper documents, including a(More)
We introduce the concept of reactive information environments and a general infrastructure for experimentation with such systems. Its asynchronous state-based processing model is described along with the architectural requirements and main components of our infrastructure. These include a general context engine coupled together with a web publishing(More)
