This paper describes a research strategy in which complex data sets are represented as physical objects in a virtual 3-D environment. The advantage of such a representation is that it allows the observer to actively explore the virtual environment so that potential ambiguities found in typical 3-D projections could be resolved by the transformation resulting from the change in viewing perspective. The study reported here constitutes an initial condition in which subjects compared relative size of virtual cubes from two different viewpoints. These results can serve as a basis for construction of cube-like objects representing the underlying conceptual structure of a data set
