Sutcliffe, Alistair G. and Patel, U. K. (1993): The Three-Dimensional Graphical User Interface: Evaluation for Design Evolution. 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. 311-331.

“The design of a three-dimensional interactive graphical user interface for a medical knowledge based system is described. A prototype of the design has been developed and evaluated. The evaluation study investigated usability, and individual differences in patterns of interaction. We found that there are individual differences in the way users explore three dimensional visualisations, and that usability is dependent on both the morphology (visualisation) and manipulations (interface functionality). While three-dimensional graphics can help reduce representational complexity, other forms complexity are intrinsic to the medium and require design solutions. Implications of these findings for design evolution are discussed.”

Patel, U. K. and Sutcliffe, Alistair G. (1993): Three-Dimensional Visualisation of Knowledge Structures: Prototyping for Design Evaluation. In: East-West International Conference on Human-Computer Interaction: Proceedings of the EWHCI93 1993. pp. 50-70.

“A conceptual framework for specification of 3D visualisations is introduced, and a task knowledge modelling approach to designing 3D visualisations of knowledge structures is described. Using this approach, a three-dimensional interactive graphical user interface to a medical diagnosis knowledge based system has been designed and specified. The design has been implemented as a prototype and evaluated. We found that there are individual differences in the way users explore three dimensional visualisations, and that usability is dependent on both the morphology (visualisation) and manipulations (interface functionality). Implications of these findings for the design of 3D visualisations are discussed.”
