Coding techniques for process plant VDU formats

The results of a literature survey of human performance and coding techniques are presented. Recommendations are given for the application of coding techniques to the design of VDU formats (screen layouts) in a process plant context. The coding techniques considered are colour, brightness, inverse video, flash, size and shape. The recommendations discuss the relative merits of the different techniques for presenting plant information, and the practical problems of applying a particular code. Some suggestions are given for further work.
