Visualisation: Linking Computation with Cognition

David Duke

(University of Bath)

Visualisation applications, like interactive systems in general, rely fundamentally on human cognitive abilities to interpret and respond to the information presented. At the level of perception, there is a signficant body of theory available to help in designing graphical representations. However, visualisation tasks and interfaces increasingly require a deeper understanding of the role played by higher levels of cognitive processing, for example how we navigate through representations of abstract spaces. Building links between the practical development of visualisation tools or methods, and theoretical models of human-information processing, is a challenge, not in the least because of the different disciplines involved. In this talk I will describe some of the problems that arise in "information visualisation", and set out an approach that may provide the insight needed to address some of these issues.
