Foundations for Designing User-Centered Systems

Frank E. Ritter is a professor in the College of Information Sciences and Technology, professor in the Department of Psychology, and professor in the Department of Computer Science and Engineering at The Pennsylvania State University. He has published more than 100 articles and conference papers, and edited several books in the area of cognitive modeling, cognitive architectures, human-computer interaction, and learning. He is on the editorial board of Proceedings of the Human Factors and Ergonomics Society and Artificial Intelligence and the Simulation of Behaviour Quarterly.

Gordon D. Baxter is a research fellow in the School of Computer Science at the University of St. Andrews. His background is in human factors and software engineering, with extensive experience in both. His research interests lie in trying to improve the way that systems are developed, and is interested in understanding how decisions and actions taken at all levels (regulatory, organisational, team and individual) affect what happens at the sharp end of the system where the user interacts with the technology His work is influenced by ideas from Resilience Engineering, and Cognitive Systems Engineering which means thinking more functionally about systems as a whole (i.e. people, technology and organisations) rather than taking an atomistic decomposition (or reductionist) type of approach, and focusing on successes as well as failures as a source of learning opportunities.
