Mobile visualisation techniques for large datasets

With the increasing popularity of mobile devices and data demands, it seems appropriate to provide mobile users with tools to understand information on their devices. Visualisations can be quick and powerful aids for data analysis and information acquisition. This paper discusses the visualisation and interaction techniques that exist on the mobile platform. It further discusses the design and development of a visualisation application that uses categorical and geographic data on the mobile platform followed by a description of a user study conducted to investigate the appropriateness of the developed mobile visualisation application. The paper further presents some of the initial findings from the user study and discusses lessons learned in visualising large geographical and categorical data sets on mobile devices.
