Knowledge Based Diffusion - A Case Study Experience

This paper builds upon the previous research of Beynon-Davies and Williams (2003) and their knowledge-based model of the diffusion of Information Systems Development Methods (ISDMs). Through the lens of the implementation of a UK government IS development project we consider how a Rapid Application Development approach was unbundled and contextualized and highlight the problems experienced. We further reflect how evidence from this empirical case confirms the efficacy of many of the elements of the diffusion model and suggest a number of directions for extending this framework, enabling better understanding of the practical application of ISDMs within organizations

Patterns of place:an integrated approach for the design and evaluation of real and virtual environments

This chapter describes an approach to the development of virtual representations of real places. The work was funded under the European Union’s €20 m Future and Emerging Technologies theme of the 5th Framework Programme, “Presence”. The aim of the project, called BENOGO, was to develop a novel technology based on real-time image-based rendering (IBR) for representing places in virtual environments. The specific focus of the work presented here concerned how to capture the essential features of real places, and how to represent that knowledge, so that the team developing the IBR-based virtual environments could produce an environment that was as realistic as possible. This involved the development and evaluation of a number of virtual environments and the evolution of two complementary techniques; the Place Probe and Patterns of place

Evaluating Adaptive Navigation Support

From the few evaluations of adaptive navigation systems that have been performed, we see an emerging pattern where depending upon the domain, only certain types of adaptive navigation works. The results indicate that adaptations should leave the interface somewhat predictable, it should not force users to interpret advanced annotations, and finally, the adaptation should not change the structure of the information space. Furthermore, evaluations of adaptive navigation support systems fail to recognise some of the more important aspects of why certain systems provide better support than others. These studies typically measure task completion time, or how well the structure of the space is remembered. While these are among the important measurements that should be taken, other features, such as how much anxiety the system induces in users, how pleasant it is to navigate, or how much users actually learn of the information contained in the space, might be more crucial measurements
