Development of modern context-aware applications requires the acquisition and interpretation of data from one or more sensors. This paper presents a framework designed to enable developers of such applications to focus on high level design and functionalities rather than spending time in low level implementation details. The framework enables this behavior(More)

Another less researched concept incorporates electronics into large textile surfaces such as carpets and upholstery. In this paper we explore methods and challenges of building a large surface area electronic(More)
This "work in progress" paper reports on a novel approach to pedestrian tracking in confined areas which is based on a combined use of a stereo vision tracking system and a set of sensors available on a mobile platform. This platform is a hands-free, sensory augmented, wearable computer, designed to support visits to museums and archaeological sites. The(More)
