Dissertation

Three-dimensional information space: An exploration of a World Wide Web-based, three-dimensional, hierarchical information retrieval interface using virtual reality modeling language.

This study examined the differences between a 3-D, VRML search interface, similar to Cone Trees, as a front-end to Yahoo on the World Wide Web and a conventional text-based, 1-D interface to the same database. The study sought to determine how quickly users could find information using both interfaces, their degree of satisfaction with both search interfaces, and which interface they preferred.

The results of this study suggest that, at least for simple search tasks, 1-D search interfaces are better than 3-D, VRML search interfaces. Current consumer-level computer systems are not capable of supporting 3-D, VRML interfaces of any complexity. Without the speed and complexity possible with large systems, 3-D search interfaces will not perform as well as simpler search interfaces.

Information Visualization

My PhD studies focused on Information Visualization Interfaces. The paper presented here provides an overview of a number of visualization interfaces as of 1996.

Summary:

Graphical visualization interfaces provide a way to help manage and understand large amounts of information. Instead of concentrating on returning just the set of documents that the user will deem most relevant, systems should concentrate on displaying the documents in such a way that the relationship between documents returned (and, if possible, those not returned) can be easily determined. The user can then use iterative refinement processes to home in on the set of most relevant documents. Instead of the system doing all the work, visual and graphical representations allow the user's own visual processing abilities to play a key role in the retrieval process.
