Stuart K. Card
Stuart Card is a Senior Research Fellow and the manager of the User Interface Research group at the Palo Alto Research Center. His study of input devices led to the Fitts's Law characterization of the mouse and was a 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 Model
