Who, What, When, Where, How: Design Issues of Capture & Access Applications.
ABSTRACT One of the general themes in ubiquitous computing is the construction of devices and applications to support the automated capture of live experiences and the future access of those records. Over the past five years, our research group has developed over half a dozen different capture and access applications. In this paper, we present an overview of eight of these applications. We discuss the different design issues encountered while creating each of these applications and share our approaches to solving these issues (in comparison and in contrast with other work found in the literature). From these issues we define the large design space for automated capture and access. This design space may then serve as a point of reference for designers to extract the requirements for systems to be developed in the future.

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.UbiComp 2005: Ubiquitous Computing, 7th International Conference, UbiComp 2005, Tokyo, Japan, September 11-14, 2005, Proceedings; 01/2005

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.Next Generation Web Services Practices, 2005. NWeSP 2005. International Conference on; 09/2005

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.International Journal of Web Services Practices. 01/2005; 1(142):142-152.
