Stuart K. Card is a Xerox Senior Research Fellow and the manager of the User Interface Research group at the Palo Alto Research Center (PARC). His study of input devices led to the Fitts's Law characterization of the mouse and was major factor leading to the mouse's commercial introduction by Xerox. His group has developed theoretical characterizations of human-machine interaction, including the Model Human Processor, the GOMS theory of user interaction, information foraging theory, and statistical descriptions of Internet use.
These theories have been put to use in new paradigms of human-machine interaction including the Rooms workspace manager, papertronic systems, and the Information Visualizer. The work of his group has resulted in a dozen Xerox products as well as the contributing to the founding of three software companies, Inxight Software, Outride, and Content Guard.
Card is a co-author of the book The Psychology of Human-Computer Interaction, a co-editor of the book Human Performance Models for Computer-Aided Engineering, and has served on many editorial boards, government panels, and university review boards.
He received his A.B. in Physics from Oberlin College and his Ph.D. in Psychology from Carnegie Mellon University, where he pursued an interdisciplinary program in psychology, artificial intelligence, and computer science. He has been an adjunct faculty member at Stanford University.
His most recent book, Readings in Information Visualization, co–written and edited with Jock D. Mackinlay and Ben Shneiderman, was published in 1999. He co-invented a number of visualizing techniques, including Cone Trees, the Perspective Walls, etc., edited with George Robertson and Jock D. Mackinlay. Card is currently developing a supporting science of human-information interaction and visual-semantic prototypes to aid sensemaking. In past he was concentrating with Peter Pirolli on a theory of information use and working on new user interfaces and services for the internet. Card is a Fellow of the ACM, the first recipient of the ACM CHI Lifetime Achievement Award, and the first member of the ACM CHI Academy.
