Douglas, S.A., Hundhausen, C.D., & McKeown, D. (1995). Toward empirically-based software visualization languages. Proceedings of the 1995 IEEE Symposium on Visual Languages. Also appears as Tecnical Report CIS-TR-95-12, Department of Computer & Information Science, University of Oregon, Eugene.

Illustrates the manner in which a research method called visualization storyboarding, together with a semantic-level analytical framework, can be used to derive an empirically-based, semantic-level software visualization (SV) language for the bubblesort algorithm. Demonstrates how the semantic-level language can be used as a framework for evaluating the usability of existing computer-based SV systems.

Douglas, S.A., McKeown, D., & Hundhausen, C.D. (1994). Exploring human visualization of computer algorithms. Technical report CIS-TR-94-27, Department of Computer & Information Science, University of Oregon, Eugene, OR.

Describes s a series of empirical studies that used conversational analysis and constructive interaction to explore the human conceptualization of computer algorithms.

Hundhausen, C.D. Exploring customizable visualization interaction.

This is my current directed research project. Using an experimental, data-reactive visualization language called Viz (new 30 page Viz reference manual available!) as a basis, I am developing an interactive environment for specifying customizable, semantics- or purpose-based visualization interfaces. News flash: An updated progress report (as of 20 March 1995) is available!

Hundhausen, C.D. (1994). Toward the development of highly interactive software visualization systems: A user-centered approach. Paper presented at the International Workshop on Software Visualization, SIGCHI '94 (Boston, MA).

Outlines the human-process centered approach to interactive software visualization that has formed the foundation of my research, and describes my forays into exploring two of those processes using a research technique called constructive interaction.

Hundhausen, C.D. (1993). Exploring the potential for conversational analysis in the evaluation of interactive algorithm visualization systems. (Appendix B comes as a separate document.) Unpublished technical report, Department of Computer & Information Science, University of Oregon, Eugene, OR.

Thoroughly documents a usability study I conducted on Lens, an interactive, single-user software visualization system developed by S. Mukherjea and J. Stasko at the Georgia Institute of Technology.

Hundhausen, C.D. (1993). Subverting the comparative research paradigm: The potential for ethnomethodology in evaluating the effects of algorithm visualization on learning. Unpublished technical report, Department of Computer & Information Science, University of Oregon, Eugene, OR.

Presents a polemic against using factors analysis as a means for assessing the effects of algorithm visualization on learning, drawing extensively from the first ever empirical study to consider the value of algorithm visualization as a learning aid (viz., J. Stasko, A. Badre, & C. Lewis. "Do algorithm animations assist learning? An empirical study and analysis. In Proc. INTERCHI '93 (Amsterdam, The Netherlands), pp. 61-66, 1993).

Hundhausen, C.D., & Malony, A.D. (1993). ObjectView: A software design architecture for breakpoint-based program visualization. Techical report CIS-TR-93-22, Department of Computer & Information Science, University or Oregon, Eugene OR.

Describes a distributed architecture for breakpoint-based program monitoring and visualization.

Hundhausen, C.D. (1993). The search for an empirical and theoretical foundation for algorithm visualization. Unpublished technical report, Department of Computer & Information Science, University of Oregon, Eugene, OR.

Critically assesses the claims that computer scientists have made about algorithm visualization systems by attempting to quantify and qualify their benefits. The analysis draws from around 50 published sources spanning several disciplines, including cognitive psychology, cognitive science, and computer science.

Naps, T.L, & Hundhausen, C.D. (1991). The evolution of an algorithm visualization system. Proc. 24th Annual Small College Computing Symposium (Morris, MN), 252-257.

Describes the four-year evolution of the GAIGS (Generalized Algorithm Illustration through Graphical Software) algorithm visualization system, which has been used as the basis for the laboratory component of Lawrence University's computer science courses since 1988. PC- and Windows-based versions of the system, complete with extensive documentation and supporting software, are available via anonymous ftp from Lawrence's ftp site in the /anonymous/math directory.
