Today's mobile devices represent exceptional foundations for wide-area Internet of Things (IoT) applications. However, the vast heterogeneity of real-world environments makes it challenging for applications to sense, understand and adapt to the user's continually evolving context. We're investigating a new community-based approach for context-aware(More)
The Web has rapidly evolved from a static informational medium into a highly capable interactive application platform. Today, Web browsers have become the de facto interface for many networked applications; however, conventional Web browsers are still unable to directly interact with the broad range of context sources and actuators available in highly(More)
Context-awareness is becoming an important foundation of adaptive mobile systems, however, techniques for discovering contextually relevant Web content and Smart Devices (i.e., Smart Resources) remain consigned to small-scale deployments. To address this limitation, this paper introduces Ambient Ocean, a Web search engine for context-aware Smart Resource(More)
Emerging demographic changes require new technical solutions to serve the growing elderly population in many countries around the world. Ambient Assisted Living approaches promise to deliver context-aware, personalized services designed to help elderly people live healthier and more autonomous lives. In this direction, we are developing the SmartAssist(More)
In this paper we present Paranoia Syndrome as a novel hybrid game approach. Paranoia Syndrome combines classic multiplayer strategy game elements using 2D computer graphics on PDAs with location-based interaction paradigms in physical space using RFID technology and tangible objects. The combination of virtual and physical reality interaction in addition to(More)
With pervasive gaming, novel types of games have recently emerged. The idea is to apply pervasive computing technology which embeds computers in real-world, everyday environments to games. By bringing gaming back to natural, social interaction spaces, pervasive gaming aims to overcome some restrictions of conventional computer games: Players are no longer(More)
The Web of Things (WoT) aims to extend the Web into the physical world by promoting the adoption of Web protocols by situated services and smart objects (ambient artifacts). However, real-world ambient artifacts often adopt proprietary and/or non-Web protocols, making them invisible to Web search engines and inaccessible to conventional Web agents. Smart(More)
In this paper we investigate a seamless method for the adaptation of streamed media by using simultaneous processing chains. The common approach for media adaptation is to deconstruct the current media processing chain and to construct a new media chain afterwards. As a consequence, media frames might be lost and the adaptation cycle needs significant time.(More)
In this paper we describe a novel approach for interactive cinema based on context-aware narration using handheld computers. The paper describes both the artistic approach and the ubiquitous computing framework developed to realize the scenario. This framework has been used in various projects, including the described video production course at the ISNM,(More)
