✦ Synopsis
The initial intent of this project was to locate any and all information pertaining to visual display characteristics as they relate to human visual functions or to visual training requirements. A selected literature search was conducted to locate relevant information, databases or taxonomies that relate the above information. No current taxonomy of this kind was located; therefore, the efforts of the project turned in the direction of formulating a taxonomic structure based on information derived from various disciplines such as instructional technology, human psychology and computer engineering. General guidelines only, with no specific information, pertaining to the selection of visual media for given situations were found in the instructional technology literature. Based on those guidelines, four general types of presentation media were selected: alphanumerics, 2-dimensional graphics, 3-dimensional graphics, and scene quality. Next, display specifications for these presentations were identified through the aid of engineering and vendor-provided design parameters. Finally, human limitations were applied and psychophysical transformations allowed the determination of final display descriptions. 23.2.34 (123639) Matthews, M. L. Evaluation of human engineering guidelines for the use of colour in CRT displays in two task environments. In: L. Berlinguet and D. Berthelette (eds). Work with Display Units 89, 1990, pp 499--504, 6 refs.
Recent ergonomics guidelines for the implementation of colour in CRT displays are evaluated in proof-reading and visual search task environments. No evidence is obtained to suggest a significant effect of colour on either performance or well-being. It is suggested that present guidelines are based upon an insufficient diversity of experimental data and have limited generality in their application to many task environments.
