Mehlenbacher, Brad, Duffy, Thomas M. and Palmer, James E. (1989): Finding Information on a Menu: Linking Menu Organization to the User's Goals. In Human-Computer Interaction, 4 (3) pp. 231-251

“Design paradigms often ignore the diverse goals users bring to the computer interface. Any human-computer interaction can be viewed as a marriage of two systems: The user begins the interaction by formulating an information goal, and the computer software meets that goal with a sometimes complex list of potential topic areas. The user then accesses that topic list through the computer interface. Part of the act of accessing the topic list is selecting a potential topic, and this action is often supported by a menu interface. Although research is pervasive on how best to organize menu items to facilitate learning, search speed, and reduced selection errors, little has been done to examine the impact of different types of user goals or cues on a menu's effectiveness. In a study using three distinct cues -- direct match, synonym, and iconic -- and two menu organizations -- alphabetical and functional -- data suggest that (a) the functional menu is more effective than the alphabetical menu for the synonym and iconic cues, (b) learning occurs with both menu designs (i.e., selection speed increases rapidly across the five trial blocks), and (c) users make fewer errors with the functionally organized menu. The results, in general, encourage more rigorous investigation of the interaction between the tasks users bring to menu interfaces and the optimal design of those menus.”

Palmer, James E., Duffy, Thomas M., Gomoll, Kathleen M., Gomoll, Thomas, Palmquist-Richards, Jessica and Trumble, John A. (1987): The Design and Evaluation of Online Help for UNIX Emacs: Access Mechanisms. In: Bullinger, Hans-Jorg and Shackel, Brian (eds.) INTERACT 87 - 2nd IFIP International Conference on Human-Computer Interaction September 1-4, 1987, Stuttgart, Germany. pp. 461-466.

“We discuss the use of the card sort technique and cluster analysis for determining an effective organization for a help menu in Unix EMACS. We gathered similarity data using a card sorting task with EMACS commands. We then used hierarchical cluster analysis to analyze the data. The results indicate that differences among novices, intermediates, and experts appear with computer-based concepts such as windows and buffers, but that the sorts are more similar than they are different. We argue that cluster analysis may aid designers in determining a functional organization, but that in our domain, this organization will not help users bridge the mapping from real world tasks to computer tasks.”

“ Software design is the act of determining the user's experience with a piece of software. It has nothing to do with how the code works inside, or how big or small the code is. The designer's task is to specify completely and unambiguously the user's whole experience. ”

-- David Liddle, From Bringing Design to Software, edited by Terry Winograd, 1996 ”
