This paper introduces the notion of context-aware mobile hypermedia. Contextawareness 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 directly. When being mobile the user may achieve context-aware hypermedia support on a variety of small and medium sized computing platforms such as mobile phones, PDAs, tablet PCs and laptops. This paper introduces the HyCon (HyperContext) framework with an architecture for context-aware hypermedia. The architecture includes interfaces for a sensor tier encapsulating relevant sensors, and it represents the hypermedia objects in structures based on the XLink and RDF standards.A prototype called the HyConExplorer created with the framework is presented, and it is illustrated how the classical hypermedia features such as browsing, searching, annotating, linking, and collaboration are supported in contextaware hypermedia. Among the features of the HyConExplorer are real-time locationbased searches via Google collecting hits within a specified nimbus around the user's GPS position. Finally, use scenarios for and evaluation of the use of the HyConExplorer in public school projects are discussed.

Abstract. 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 supporting drama writers in developing such Mobile Urban Dramas. Experiences with use of the framework are discussed with successful examples of real dramas that have been developed and performed by a Danish theatre group, Katapult.

Modern project-based education requires students to be able to work with digital materials both in and out of the classroom. Field trips are often an integral part of such projects and greatly benefit studentsâ?? learning by allowing them to engage with real-world environments first-hand. However, the infrastructure for accessing context sensitive information and supporting in-situ authoring by students while in the field is often lacking. In this paper we present the HyCon framework for mobile, context-aware, and multi-platform hypermedia that aims at supporting several aspects of fieldtrips and project-based education.

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 outof-school learning projects by introducing support for solving assignments and producing multimedia-based documentation for learning purposes. Media production is seamlessly supported through a context-aware media management system. The Mobile Urban Drama project, "HASLEINTERACTIVE", is presented. It supports biology, geography and math lessons for 7 th to 9 th graders in schools. The story is an environmental thriller that takes place partly on the pupils' mobile phones and partly in the real worldin nature, which must be investigated through exercises. The level of pupil engagement is evaluated through interviews with teachers and pupils, as well as an analysis of pupil productivity and produced media materials during the interactive Mobile Urban Drama experience. It is argued how the out-of-school learning features are successfully supported by the system, and we conclude that the level of productivity and engagement is higher than in usual pupil group work.
