Stuart Card

Stuart K. Card (born ca. 1946), an American researcher and Senior Research Fellow at Xerox PARC, is considered to be one of the pioneers of applying human factors in human–computer interaction. His study of input devices led to the Fitts's Law characterization of the computer mouse and was a major factor leading to the mouse's commercial introduction by Xerox, most notably in the Alto and Star projects, some of the very earliest GUI systems employing a desktop metaphor. The 1983 book The Psychology of Human-Computer Interaction, which he co-wrote with Thomas P. Moran and Allen Newell, became seminal work in the HCI field. Further research into the theoretical characterizations of human–machine interaction led to developments like "the Model Human Processor, the GOMS theory of user interaction, information foraging theory, and statistical descriptions of Internet use". In the new millennium his research has been focusing on developing a "supporting science of human–information interaction and visual-semantic prototypes to aid sense making".
