Abstract

Recent research on Ambient Information Systems has explored the provision of information systems across a wide range of deployment contexts with emphasis on user mobility and location-oriented information delivery. Such work has resulted in a broad spectrum of concrete outcomes regarding design approaches for information presentation ?on the move? with primary emphasis on unobtrusive feedback, context-sensitive information mining and overall aesthetic quality. Additionally, the consolidation of such work seems to lead to somehow standardized technical vocabulary regarding the primary requirements of mobile information systems, the dominant software design patterns, micro and macro architectures, structure of information and the technical approaches to location sensing. However, there is no systematic work on addressing the implementation of these systems by proposing a universal set of basic building blocks and architectural elements. We argue that the general domain of ambient intelligence would significantly benefit from the identification of prominent building blocks for ambient information systems. The collection of building blocks is comprised of a data access layer, a location-sensing layer, a synchronization service and a mobile location-administration system. For each building block, we provide a systematic account of the main challenges it addresses in the context of ambient information systems. The data access layer provides a flexible mapping between physical artifacts within the environment and objects within the relational database. The location-sensing layer allows us to query the wireless infrastructure to retrieve user positions in real time. The synchronization layer allows us to ensure that information mirrored in distributed resources remains always up to date. Finally, the mobile location-administration system allows the administrator to interactively program -on site- the physical position of information elements.
