Blatt, Louis A., Zacherl, Anna and Jacobson, Mark (1993): Representing Examples in a User Interface Design Guidance System. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 291-294.

“Research shows that developers and designers alike use examples in their design process. However, the tools that developers and designers use are difficult to use because they provide few or no examples and require extensive reading and memorization. This study gave developers and designers a background questionnaire and asked them to design an interface for displaying and exploring user interface examples within a user interface design guidance system. Analysis of audio tape, screen layouts, and user and task profile data from the study provided a number of user interface requirements for systems that support the representation and use of user interface examples.”

Blatt, Louis A. and Knutson, James F. (1993): User Interface Design Guidance Systems. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. p. 1038.

“Despite the wide acceptance of standard user interface platforms, style guides, and software tools, many human-system interfaces are still difficult to use. An user interface design guidance system (UIDGS) is any collection of tools that supports a software developer or designer in creating human-system interfaces. Current UIDGSs are insufficient. Some criticisms of design guideline documents, a popular form of UIDGS, are that they do little to ensure task consistency (Potter et al., 1990), are not well-suited for use during development (Thovtrup and Nielsen, 1991), are often too general (Chapanis, 1990) and are perceived as limiting creativity. These factors have inhibited the adoption of UIDGSs within the mainstream of software development. The current research addresses this problem through demonstration of a prototype UIDGS.”

Blatt, Louis A. and Schell, Alan (1990): Gesture Set Economics for Text and Spreadsheet Editors. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 410-414.

“Since the widespread acceptance of alternative input devices and the development of technology for character recognition, gestures have begun to be investigated as a potential dialog type in software applications. Inter and intra-subject consistency has been reported; however, no one has reported inter-application consistency. This paper begins to take a systematic approach to identifying a minimal set of gestures that would be necessary to operate across a series of applications. Two tasks with 15 subjects in each were conducted on the use of gestures to edit text and spreadsheets using a pencil and paper. By examining people's editing marks in these two situations, this study begins to identify the level to which gestures remain consistent across applications. The results are discussed in relationship to the implementation of an economical gestural interface for an application suite.”

Perkins, Ronald, Blatt, Louis A., Workman, Daniel and Ehrlich, Susan F. (1989): Iterative Tutorial Design in the Product Development Cycle. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 268-272.

“Early development of a tutorial fostered a joint effort between human factors professionals, software developers and training consultants that resulted in early resolution of many problems during the development of Wang Freestyle, a new multimedia communication system. It was decided that new users of Freestyle should be able to use the basic annotation features without referring to any hardcopy documentation. To ensure this, iterative tests of evolving prototypes of (1) the software and (2) an on-line tutorial that was designed to teach any features of the system that were not immediately intuitive were carried out. Changes were made in the software and the tutorial, resulting in improvements to both. The methods used and some of the lessons learned from this initial experience with iterative tutorial development are discussed.”
