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)
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 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)
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)
Imagine if your favorite social networking website provided a "Share to Screen" button that automatically dimmed the room lights and streamed your web-based photos and videos to a nearby television, projector or photo frame. Unfortunately, such fluid interactions between the Web and the physical environment remain challenging, since conventional Web(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)
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)
