Item Interactive Grid Based Binning for Information Visualization(The Eurographics Association, 2008) Longshaw, S. M.; Turner, M. J.; Hewitt, W. T.; Ik Soo Lim and Wen TangClutter within information visualization (infovis) systems is an area of continuing concern and is receiving increasing research interest. Solutions to the problem vary in their approach, ranging from novel visualizations designed specifically to cope with high data density, through to statistical methodologies such as binning. This paper presents a flexible method that allows interactive placement of a grid based binning system that aims to enhance traditional information visualization techniques. User evaluations employing two specific visualization methods are described using a prototype grid based binning system. The method is shown to be a quick and easy way to visually segment a data domain, while the two visualization techniques presented are shown to provide effective data overview. Due to the abstracted nature of the binning grid, its applicability goes beyond the examples provided in this paper, therefore it could be considered as a generic data reduction and/or overview technique within many systems.Item Modes of Virtual Environments Integrated within Collaborative Environments(The Eurographics Association, 2008) McDerby, M. J.; Turner, M. J.; Leaver, G. W.; Ik Soo Lim and Wen TangThis paper describes the timeline of large display virtual environments used by Manchester Visualization Centre and a few of the main applications of such systems. Moreover, it describes a few simple common modes of use as well as stages of development, categorising and explaining how best practice may be achieved. In addition this paper considers the development and use in the last few years of multi-functioning spaces that combine both a large scale VE with the next generation of video conferencing system. These have been used to create new modes of interaction and collaboration.
