    ABSTRACT: Context-aware applications assist users' everyday tasks by adapting their behavior based on context information obtained from instrumented environments. Context is any relevant information describing entities in a user-computer interaction (e.g. user location). The design and implementation of high-quality context management software is an area of active research. We have described elsewhere the context kernel, a Web service that manages context information on behalf of applications. In this paper, we present a case study of how the context kernel has been used to integrate a suite of e-learning applications. We show how the Web services approach allowed applications to seamlessly exchange context on the Web through a uniform context representation schema. We also present the lessons we learned from integrating e-learning applications via Web services.

    ABSTRACT: Ubiquitous computing is a user-computer interaction paradigm supporting users in everyday tasks carried out away from the desktop. The literature has exploited themes such as natural interfaces (e.g. pen-based), automatic capture and access of everyday experiences and context-aware computing. Regarding context-aware applications, context is any relevant information describing entities in a user-computer interaction (e.g. user location). The design and implementation of high-quality context management software is an area of active research. We have described elsewhere the Context Kernel, a Web Service that manages context information on behalf of applications. In this paper, we present a case study of how the Context Kernel has been used to integrate a suite of e-learning applications — a domain rich in research exploiting the ubiquitous computing themes. We show how the Web Services approach allowed applications to seamlessly exchange context on the Web through a uniform context representation schema. In particular, we discuss how our approach has allowed us to tackle an important problem of e-learning applications: the support to authoring learning object metadata. We also present lessons learned from integrating e-learning applications via Web Services.

    ABSTRACT: Building capture and access (C&A) applications for use in the opera- tion theatre differs greatly from C&A applications built to support other settings e.g. meeting rooms or classrooms. Based on field studies of surgical operations, this paper explores how to design C&A applications for the operation theatre. Based on the findings from our field work, we have built the ActiveTheatre, a C&A prototype. ActiveTheatre is built to support collaboration in and around the operating theatre, to capture events instead of automatically capturing eve- rything, and to be integrated with existing applications already present in the operation theatre. The ActiveTheatre prototype has been developed in close co- operation with surgeons and nurses at a local hospital. The work on the proto- type and our initial evaluations have provided an insight into how to design, capture and access applications that are going to be used in other settings than the meeting room.
