Towards online position information integration in a location based services gateway

Assistance Systems employing for example interactive control of building environments and indoor localization services are topics of growing relevance for ambient systems. Today there exist already a variety of indoor localization approaches and systems as well as universal remote control systems. In recent works we reported on our research on lightweight middleware offering a position related smart building services gateway. Such a system allows clients to receive visual- and contextual information about the environment and allows performing control of systems within this environment. The gateway middleware eases abstraction and integration of underlying systems and information, for example indoor localization technology, the original 3D building model data format, or existing control applications into client applications. In the current work we investigate the integration of dynamic position information using the iLoc indoor localization system and a mobile position visualization application.
