“This study presents a theoretically motivated analysis of learning and performance on a micro-processor based oscilloscope. An analysis of the knowledge required to make basic measurements was done using the GOMS model and Cognitive Complexity Theory (CCT). From these analyses and the criterion used in Polson, Muncher, and Engelbeck (1986), tasks were selected for an experiment evaluating training order manipulations using naive users of oscilloscopes. Production system models for each training task were derived from CCT. The models successfully predicted transfer between tasks and training order effects. Implications for the design of systems with embedded micro-processors are discussed.”

Knox, Stephen T., Bailey, Wayne A. and Lynch, Eugene F. (1989): Directed Dialogue Protocols: Verbal Data for User Interface Design. In: Bice, Ken and Lewis, Clayton H. (eds.) Proceedings of the ACM CHI 89 Human Factors in Computing Systems Conference April 30 - June 4, 1989, Austin, Texas. pp. 283-287.

“The development of an interface design tool called "directed dialogue protocols" is discussed. The tool is based upon Kato's (1986) method of verbal data collection, "question-asking protocols." Three extensions to the question-asking method are detailed: 1) an experimental procedure of atomic tasks which facilitate the quantization of verbal data; 2) interventions by the experimenter that probe the subject's expectations and prompt verbalizations; and 3) a technique for answering subject queries called sequential disclosure. Also discussed are applications of the directed dialogue that have identified design choices which build learnability and usability into a product's user-interface.”

Bailey, Wayne A., Knox, Stephen T. and Lynch, Eugene F. (1988): Effects of Interface Design Upon User Productivity. In: Soloway, Elliot, Frye, Douglas and Sheppard, Sylvia B. (eds.) Proceedings of the ACM CHI 88 Human Factors in Computing Systems Conference June 15-19, 1988, Washington, DC, USA. pp. 207-212.

“Eight subjects experienced in the use of both 7000 and 11000 series oscilloscopes performed four typical tasks with each scope. The 7000 interface is a dedicated physical control system, while the 11000 system employs icons, pop-up menus, assignable controls, and a touch panel. On each trial the task time and measurement accuracy were recorded. Each experimental session was video recorded and verbal protocols were collected. These allowed decomposition of the subjects' behaviors into categories that would account for performance differences between the two scopes. A 77% performance difference is explained in terms of the cognitive factors of strategy selections and recall of operational details.”
