UofT Department of Computer Science Seminar Schedule for
the week of March 19th, 1984
Tuesday, March 20th, 3:00 P.M., GB244: Dr. Teresa Roberts,
XEROX PARC: "Human factors testing in the design of Xerox's
8010 'Star' office workstation".
ABSTRACT: Integral to the design process of the Xerox 8010
"Star" workstation was constant concern for the user interface.
The design was driven by principles of human cognition.
Prototyping of ideas, paper and pencil analyses, and human-factors
experiments with potential users all aided in making design
decisions. Three of the human-factors experiments are described
in this paper: A **selection schemes** test determined the
number of buttons on the mouse pointing device and the meanings
of these buttons for doing text selection. An **icon** test
showed us the significant parameters in the shapes of objects
on the display screen. A **graphics** test evaluated the user
interface for making line drawings and resulted in a redesign
of that interface.
Contact Bill Buxton (978 6320 or utcsrgv!willy) for more information.
Dr. Roberts is a member of the research staff at XEROX PARC. She did
her Ph.D research jointly at Stanford and XEROX on the comparative
evaluation of text editors.
