ALADIN

Mobile Infrastructure for location-based Services

Supervisor: Prof. Dr. Andreas Schrader Participants: Darren Carlson Subjects: Ubiquitous Computing, Mobile Services

Aladin is a context-aware computing approach, which explores how commodity devices can be dynamically adapted to acquire and model a diverse range of context information using local available hardware and software.

Aladin is specifically designed to automatically acquire and model context information in large-scale, cross domain scenarios without requiring significant context instrumentation or related infrastructure. Aladin provides a domain-neutral, client-centric approach that dynamically extends the context modeling capabilities of commodity mobile devices through the use of runtime deployed plug-ins. Client-side Aladin software enables devices to adapt their context acquisition and modeling capabilities by performing ongoing capability analyses and integrating platform-specific context acquisition and modeling plug-ins on-the-fly.

Several ISNM projects are based on the ALADIN infrastructure, which is continously updated: Echoes, Paranoia Syndrome, Interactive Cinema.
