The designer of human-computer interfaces needs to be able to predict human behaviour from interface design indices. A feasibility study used multivariate techniques to relate a particular set of indices to human performance. Good descriptive fits were obtained for UNIX, Mackintosh and VisiOn tasks. Further analysis suggests that different types of interface may require different sets of indices and weights. Future work will require development of descriptive languages for designers, human-computer interaction models which indicate which aspect of the design should be measured, and techniques for processing descriptions to produce the indices such as expert systems. Multivariate techniques of fer considerable promise for error prediction.
