Supporting Knowledge and Expertise Finding within Australia's Defence Science and Technology Organisation

This paper reports on work aimed at supporting knowledge and expertise finding within a large Research and Development (R&D) organisation. The paper first discusses the nature of knowledge important to R&D organisations and presents a prototype information system developed to support knowledge and expertise finding. The paper then discusses a trial of the system within an R&D organisation, the implications and limitations of the trial, and discusses future research questions.

An Exploratory Study of Mobile Computing Use by Knowledge Workers

This paper describes some preliminary results from a 20-week study on the use of Compaq iPAQ Personal Digital Assistants (PDAs) by 10 senior developers, analysts, technical managers, and senior organisational managers. The goal of the study was to identify what applications were used, how and where they were used, the problems and issues that arose, and how use of the iPAQs changed over the study period. The paper highlights some interesting uses of the iPAQs, and identifies some of the characteristics of successful mobile applications.

Activities, Context and Ubiquitous Computing

Context and context-awareness provides computing environments with the ability to usefully adapt the services or information they provide. It is the ability to implicitly sense and automatically derive the user needs that separates context-aware applications from traditionally designed applications, and this makes them more attentive, responsive, and aware of their user's identity, and their user's environment. This paper argues that context-aware applications capable of supporting complex, cognitive activities can be built from a model of context called Activity-Centric Context. A conceptual model of Activity-Centric context is presented. The model is illustrated via a detailed example.
