Sage Journals: Discover world-class research

Abstract

In this study two three-dimensional information displays were designed and tested which could provide alternative display formats to traditional two-dimensional bar graphs. The intent was to design displays that supported both low level focused attention tasks and high level integration of information. The proposed display representations were generated, based on perceptual emergent features theories, in the form of a curvature and gap display. An empirical comparison of the three-dimensional displays versus a two-dimensional bar graph indicated marginally enhanced performance for both focused attention and integrated tasks when using the curvature and gap displays. The novelty of the three-dimensional displays was suggested to contribute to a learning effect which was may have reduced the reliability of the results. Future research should examine similar displays with extended sessions to overcome this learning effect.
