David Modjeska: PARALLEL WORLDS PROJECT: OBJECT-BASED VS. TEXT-BASED REPRESENTATIONS OF INFORMATION STRUCTURE IN VIRTUAL WORLDS

Navigation is central to information seeking in electronic worlds. Previous research on the physical world and virtual ones has considered the impact of environmental structure on navigation and learning. Such structure can be either object-based or text-based. We are engaged in a series of experiments to evaluate the effects of combining object and text representations of information structure in different ways in virtual reality(VR). By observing users in several virtual (and hypertext) worlds with similar information structures, we hope to extract guidelines for the use of object-based and text-based representations in VR design. To assess the validity of the VR approach, we have made baseline comparisons of perception and performance in hypertext versus VR representations of similar information structures. information structures.
