van Aalst, J. W., Carey, T. T. and McKerlie, Diane L. (1995): Design Space Analysis as "Training Wheels" in a Framework for Learning User Interface Design. In: Katz, Irvin R., Mack, Robert L., Marks, Linn, Rosson, Mary Beth and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 95 Human Factors in Computing Systems Conference May 7-11, 1995, Denver, Colorado. pp. 154-161.
Learning about design is a central component in education for human-computer interaction. We have found Design Space Analysis to be a useful technique for students learning user interface design skills. In the FLUID tool described here, we have combined explicit instruction on design, worked case studies, and problem exercises for learners, yielding an interactive multimedia system to be incorporated into an HCI design course. FLUID is intended as a "training wheels" for learning user interface design. In this paper, we address the question of how this form of teaching might mediate and extend the learning process and we present our observations on Design Space Analysis as a training wheels aid for learning user interface design.

Carey, T. T., Ellis, M. S. and Rusli, M. (1993): Reusing User Interface Designs: Experiences with a Prototype Tool and High-Level Representations. In: Alty, James L., Diaper, Dan and Guest, D. (eds.) Proceedings of the Eighth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers VIII August 7-10, 1993, Loughborough University, UK. pp. 203-216.
A library of user interface design exemplars is being constructed to aid designers in learning from and reusing existing artifacts. Reuse concepts from software engineering have been applied to the design of the library. Experiments are underway to test usage-oriented design representations for incorporation in the library. Several scenarios of potential use are suggested.

INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 43-46.
ABSTRACT. This paper describes a large scale analysis of user error in the Unix environment. Over 300,000 commands were logged containing approximately 16,000 errors. The errors detected included various kinds of token entry problems, mode errors, keyboard errors and grammatical mistakes. The relative frequency of each type is presented. The paper concludes with a discussion of a number of improvements that could be made to the Unix csh command interface.

Hendry, D. G., Carey, T. T. and TeWinkel, S. T. (1990): A Study of Measures for Research in Hypertext Navigation. In: Diaper, Dan, Gilmore, David J., Cockton, Gilbert and Shackel, Brian (eds.) INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 101-106.
The research described here investigated the strategies people use to navigate a hypertext document in reading comprehension tasks. We present the results from experiments where people were initially instructed to browse and later to study a document containing expository information on 35 mm. cameras. The users interacted with the document through one of two presentation methods: traditional page sequences or access by hypertext links. A variety of measures were used to illuminate users' navigation strategies: Each of these measures contributes in a different way to our overall understanding of users' navigation (and raises additional questions).

Carey, T. T., Hunt, W. T. and Lopez-Suarez, A. (1990): Roles for Tables of Contents as Hypertext Overviews. In: Diaper, Dan, Gilmore, David J., Cockton, Gilbert and Shackel, Brian (eds.) INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 581-586.
Hypertext documents can provide increased access to information. However, users can experience disorientation as they jump between units in a document. This "lost in hypertext" phenomena is often thought of as a way-finding problem, to be solved by overviews of navigational structure. But we argue that it is often a problem of making sense of the document when the access sequence does not reflect its organizational structure, so that overviews must preserve and extend the user's organizational view. The paper describes a prototype overview aid, TableView, for users of hypertext systems. Extensions to traditional tables of contents allow TableView to integrate several roles for hypertext navigation aids. We discuss application of TableView for an online help system, and future extensions to incorporate additional overview roles.

We have experimented with the impact of a fisheye view on graphical presentations for topographic networks. Subjects selected optimal routes between stations on a fictional subway network, using either a scrolling view or a fisheye view. Performance using a fisheye view was superior when the destination station was not visible in the initial display; performance with scrolling was superior when both stations were visible and when more complex itineraries were required. Scrolling performance improved over time with two-station routes; the fisheye performance improved in the (later) itinerary task.

Carey, T. T., Borr, A. H. and Graham, C. H. (1989): Experimental Implementation Techniques for User Interface Adaptation. In: Proceedings of the Third International Conference on Human-Computer Interaction 1989. pp. 526-532.
We are currently studying two new techniques for implementation of user interfaces. One experimental implementation provides UI designers with a design toolkit using actors, allowing dynamic delegation of interface behaviours. The actors are defined in a frame-based structure which permits a flexible delegation scheme. We illustrate how this flexibility can be used to potential advantage in adaptive interfaces. The second technique, active data distribution, is being developed for use in a distributed processing environment. A typical target situation would have a personal workstation providing user interface facilities, for access to a data server through a network connection. When access to the data causes delays in interaction, the user interface can anticipate requests and pre-fetch data, using a task model to adapt its data distribution strategy. Our experiments, run using a computer conferencing system as the host application, demonstrate the improvements in response times possible with this technique, and also some of the limitations it imposes.

A specification model for user interfaces is illustrated by examples from a computer conferencing system and a personal computer paint package. The examples show formal methods for describing the semantics of application-independent interaction styles, and for condensing a specification using designers' conceptual abstractions.
