Project based education is growing in importance in elementary schools though it is still quite poorly technologically supported, particularly with respect to actively taking advantage of contextual information. Based on an empirical study of teaching and in particular project based education in Danish elementary schools, we present the HyConExplorer, a(More)
This paper presents applications of HyCon, a framework for context aware hypermedia systems. The HyCon framework encompasses annotations, links, and guided tours associating locations and RFID- or Bluetooth-tagged objects with maps, Web pages, and collections of resources. The user-created annotations, links and guided tours, are represented as XLink(More)
This paper introduces the notion of context-aware mobile hypermedia. Context-awareness means to take the users' context such as location, time, objective, community relations etc. into account when browsing, searching, annotating, and linking. Attributes constituting the context of the user may be sensed automatically and/or be provided by the user(More)
This paper introduces the novel concept of location-based Mobile Urban Dramas. In a Mobile Urban Drama the user become the main character in a play where actors' voices appear in the mobile phone headset linked to the physical setting in the city as the stage for the drama. The paper describes the dramaturgical concept and introduces a software framework(More)
This paper evaluates the XLink format in comparison with other linking formats. The comparison is based on Xspect, an implementation of XLink. Xspect handles transformation between an open hypermedia format (OHIF) and XLink, and the paper discusses this isomorphic transformation and generalises it to include another open hypermedia format, FOHM. The Xspect(More)
Context-aware computing focuses on developing systems which through different kinds of sensory systems are able to collect information about the physical environment in order to, more or less automatically, adapt data and behavior to the user's current context. The aim is to create systems that, rather than solely depend on explicit user input, can react to(More)
In this paper, we describe an infrastructure for browsing and multimedia blogging of Web-based information anchored with physical places in an urban environment. The infrastructure is generic in the sense that it may use any means such as GPS, RFID or 2D-barcodes as ubiquitous links anchors to anchor Web-based information, blogs, and services in the(More)
This paper describes the notion of Mobile Urban Drama and how a particular production is implemented to support engaging experiences via location-based mobile phone software. Mobile Urban Drama is a general concept that has been adapted for out-of-school learning projects by introducing support for solving assignments and producing multimedia-based(More)
