Colman, Alan W. and Leung, Ying K. (2000): Using Intentional Models for the Interface Design of Multi-Level Systems. In International Journal of Human-Computer Studies, 52 (6) pp. 1007-1029
In this paper, it is argued that the design of computer interfaces for complex, multi-layered systems needs to take into account the differing intentional models that are held by different types of users of such systems, and that there is a strong correlation between the job roles of individuals and the level of abstraction of the mental models held by such users. An approach to the analysis and design of complex multi-layered systems based on the analysis of job roles to elicit such models is suggested and linked with other techniques of task analysis and object-oriented analysis and design. The methodology is illustrated with the interface analysis for an automatic environmental chemical analyser.

Leung, Ying K., Spence, Robert and Apperley, Mark (1995): Applying Bifocal Displays to Topological Maps. In International Journal of Human-Computer Interaction, 7 (1) pp. 79-98
Presentation techniques for topological networks can be broadly classified as distortion-oriented and nondistortion-oriented. Although there has been a growing interest in applying various distortion-oriented techniques, the application of an earlier example, the bifocal display, has so far been underexploited. This article describes a number of human-computer interface techniques potentially relevant to the presentation and navigation of topological networks associated with transport systems, and describes a preliminary experimental study of a number of techniques for presenting the London Underground map as part of a real-time information system for travelers.

Leung, Ying K. and King, Richard J. (1995): Enhancing Fold Manipulation Techniques. In: Proceedings of the Sixth International Conference on Human-Computer Interaction July 9-14, 1995, Tokyo, Japan. pp. 211-216.
Folding is an effective means to overcome the inherent problem associated with displaying a large information space on a small computer screen. This technique has been successfully deployed in a variety of application domains, ranging from text editors and spreadsheets to information spaces with a tree structure hierarchy. However, this paper argues that the folding facilities currently available in many commercial products could be improved. It further proposes a number of features which may be used to enhance folding to enrich the human-computer interaction.

King, Richard J. and Leung, Ying K. (1994): Designing a User Interface for Folding Editors to Support Collaborative Work. In: Cockton, Gilbert, Draper, Steven and Weir, George R. S. (eds.) Proceedings of the Ninth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers IX August 23-26, 1994, Glasgow, Scotland, UK. pp. 369-381.
Software engineering requires the production of hierarchically organised text-based documents, such as specifications, source codes, and manuals. Folding editors are effective tools designed to support such activities involving documents of any complexity. In a collaborative work environment, especially in a large software development team, folding editors offer many advantages over the conventional editing system. Surprisingly, the use of folding editors has often been overlooked. This could partly be attributed to the generally inadequate design of their interface and partly to the lack of effective facilities available to support collaborative work. This paper identifies some of the typical difficulties associated with sharing files in a software engineering teamwork environment and discusses the advantages of folding editors to overcome these problems. It then describes the rationale of a design of a user interface for folding editors to support collaborative work.

Leung, Ying K. and Apperley, Mark (1993): Extending the Perspective Wall. In: Proceedings of OZCHI93, the CHISIG Annual Conference on Human-Computer Interaction 1993. pp. 110-120.
A visualisation tool for data with a linear hierarchical structure, known as the Perspective Wall, was proposed by a group of researchers at Xerox PARC at the CHI '91 conference. This paper explains the concept of the Perspective Wall and contrasts it with an earlier approach, the Bifocal Display. It then highlights the problems associated with the implementation of the Perspective Wall and suggests two directions for improvement. One proposal, which can be adequately implemented using currently available technology, is to extend the Bifocal Display; for systems with more computational resources, Trifocal and Quadfocal Displays are also practical. Another proposal, the Perspective Space, which is proposed as an extension of the Perspective Wall, would provide the user with a realistic 3D feel in visualising very large data spaces.

Leung, Ying K. and Apperley, Mark (1993): A Taxonomy of Distortion-Oriented Techniques for Graphical Data Presentation. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 104-109.
In recent years, there has been a growing interest in the development of distortion-oriented presentation techniques for large scale information systems. Conflicting terminologies and principles in this area have given rise to confusion amongst interface designers. This paper presents a taxonomy of these graphical techniques. It highlights their differences and similarities, enabling sensible comparisons and selections to be made.

Leung, Ying K. and Apperley, Mark (1993): E{cubed}: Towards the Metrication of Graphical Presentation Techniques for Large Data Sets. In: East-West International Conference on Human-Computer Interaction: Proceedings of the EWHCI93 1993. pp. 9-26.
Rapid advances in communications and computer technologies in recent years have provided users with greater access to large volumes of data from computer-based information systems. Whilst researchers have developed many novel techniques to overcome the problems associated with the presentation and navigation of large data sets on a limited display surface, the choice of a technique in a particular application remains very subjective. This paper proposes an evaluation framework E{cubed} which aims to provide a basis for the comparison of different presentation techniques, given the nature and characteristics of the data to be presented, and the interpretation required. E{cubed} focuses on three aspects of graphical data presentation: expressiveness, efficiency, and effectiveness. This framework lays the foundation for the development of a set of metrics to facilitate an objective assessment of presentation techniques.

Howard, Steve and Leung, Ying K. (1991): Interacting with Graphical User Interfaces: States, Processes and Resources. In: Proceedings of OZCHI91, the CHISIG Annual Conference on Human-Computer Interaction 1991. pp. 47-52.
A study aimed at understanding user interaction with map-based user interfaces is presented. The study concerns itself with user modelling issues, rather than with the utility of the user interface per se. In accounting for the observed behaviour (in terms of a conception based upon three constructs: states, processes and resources) current theoretical work in modelling HCI is extended.

Leung, Ying K. (1989): Human-Computer Interface Techniques for Map Based Diagrams. In: Proceedings of the Third International Conference on Human-Computer Interaction 1989. pp. 361-368.
This paper describes a number of human-computer interface techniques specifically designed to facilitate presentation and navigation of map based graphic systems. The advantages and disadvantages of these techniques are discussed. Two of these techniques, the bifocal display technique and the split screen technique have been implemented using the London Underground map on an Apollo graphics workstation. These human-computer interface techniques can well be applied to other map based diagrams such as engineering plans and electronic circuit diagrams.
