Deconstructing Space: Spatial Memory for symbols and pictures in 2D, 3D and in Deconstructed Displays
2004 (English)Report (Other (popular scientific, debate etc.))
Novel approaches in graphical user interface design propose and implement displays that make use of three-dimensional (3D) environments. 3D displays are often presented as efficient options to support the storage and retrieval of abstract and textual data. Empirical results show that the successful accomplishment of such tasks can be improved by interaction with three-dimensional interfaces. However, it is still unclear what specific visual properties of three-dimensional displays that better support such tasks. In order to investigate this issue a three-dimensional "ecological" representation of hierarchically arranged data that previously has been found to be effective, was deconstructed into single and unique visual properties. These properties were pictorial cues used in two-dimensional representations to induce the perception of depth, specifically the relative sizes of the objects represented and the arrangement of the objects over a planar surface. These cues were isolated and a deconstructed version of the 3D display was created. In two experiments, the deconstructed display was empirically compared to 3D and to 2D displays. The first experiment involved 39 subjects and aimed to study the contribution of the visual properties across a memory task entailing the recall of pictorial data. In the second experiment 33 subjects were requested to repeat same task using symbolic data. The results of the experiments revealed that the subjects in the 3D condition performed more accurately when pictorial information was displayed and that this was not due a higher learning time. No difference between conditions for accuracy was found when the information was symbolic, but the performance was faster in the 3D condition compared to the 2D condition.
