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. -- Phyllis Eve Bregman CSRG, Univ. of Toronto {decvax,linus,ihnp4,uw-beaver,allegra,utzoo}!utcsrgv!phyllis CSNET: phyllis@toronto (416) 978 6985
