My research has necessarily been an interdisciplinary effort, and as such, there are many persons to whom I am indebted. In particular, I owe great thanks to the Department of Neurological Surgery for supporting the work and participating in the design effort.
I would like to thank the members of my committee, and in particular, Randy Pausch, Dennis Proffitt, and John Snell, who have all worked closely with me over the past few years.
I also owe thanks to Joe Tullio for assistance with experiments, design, and implementation of testing software, and James Patten, for assistance with running experimental subjects.
I would like to acknowledge external colleagues including Yves Guiard, currently at the Cambridge Applied Psychology Unit, Bill Buxton, of the University of Toronto and Alias | Wavefront, and Rob Jacob, at Tufts University, for enlightening discussions about some of the issues raised by my work.
I have been assisted by the friendly disposition and skill of machinists Bob Frazier and Bob Bryant who helped to design and build the physical devices and apparatus which made the interface tools and the experimental equipment work.
I would like to thank the present members, graduates, and associates of the Neurosurgical Visualization Lab, including Hunter Downs, Sean Graves, Adrian Filipi-Martin, Dave Schlesinger, Dave Moore, Michelle Plantec, Minyan Shi, Greg Harrington, Delia McGarry, Bill Katz, Ted Jackson, Will McClennan, Marc Pilipuf, Jim Bertolina, Dr. Neal Kassell, Dr. Dheerendra Prasad, and Dr. Mark Quigg. Each of these individuals participated in design discussions, assisted implementation efforts, participated in pilot experiments, or provided general support, assistance, and advice in the course of my dissertation work.
I would like to thank the general support and many valuable discussions provided by members of the user interface group, including current members Steve Audia, Tommy Burnette, Matt Conway, Kevin Christiansen, Dennis Cosgrove, Beth Mallory, Kristen Monkaitis, Jeff Pierce, Joe Shochet, Brian Stearns, Chris Sturgill, John Viega, and George Williams; as well as the many graduates with whom I have worked, including Robert Allen, Jonathan Ashton, Brian Cadieux, AC Capehart, Roddy Collins, Thomas Crea, Rob DeLine, Jim Durbin, Rich Gossweiler, Simeon Fitch, Drew Kessler, Shuichi Koga, Jan Hoenisch, Chris Long, Steve Miale, Kimberly Passarella Jones, Anne Shackelford, Richard Stoakley, Jeff White, and Scott Witherell.
I also owe thanks to colleagues in the Biomedical Engineering, Radiology, and other departments who helped along the way, including Jim Brookeman, Sam Dwyer, Linda Young, and Doug Kraus.
I would like to thank members of Dennis Proffit's Perception Lab who have assisted my efforts, shared valuable experimental space with me, and offered advice on working with subjects, including Sarah Creem, Steve Jacquot, Jane Joseph, MJ Wraga, and Tyrone Yang.
Finally, I thank the many students who participated in my experiments.
