The StudyDesk system provides a workbench environment that is well suited to work with multi-dimensional volumetric data in a semi-immersive virtual-reality setting. Using the StudyDesk system, we have implemented two example volume-rendering applications. The first visualises medical volumetric data using its implicit correspondence to physical space. The second is used to visualise and analyse sonar data described by time, range, bearing and frequency dimensions, in which correlations between sub-volumes is important. Therefore an abstract representation of the dataset is used to identify important regions in the data, which are then analysed using more traditional volume visualisation techniques. Interaction is implemented through the use of personal interaction props based on a pen and pad metaphor. Props include a transparent pen and pad that carry virtual shapes and a PDA system that is also used to transfer data and contexts between various systems.
