Abstract

It is common knowledge that the human engineering of displays is equally important to electro-optical or software engineering. To make human engineering a routine part of display design we must have quantitative rules of thumb describing the performance of the human visual system. For colour visual psychophysics is the scientific discipline that creates such measurements. Some aspects of colour psychophysics are well understood, mostly concerned with very low level processes in the visual system. This paper describes where they can be useful applied in display design. It also discusses measurements needed for human performance to play a greater role in display design for a wider range of tasks.
