Stuart Card

[1][2] With Jock D. Mackinlay, George G. Robertson and others he invented a number of information visualization techniques.

He retired from PARC in 2010 but has been a consulting professor in Stanford University's Computer Science department.

Stuart Card's 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.

[7] 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.

[5] 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".
