Commonplace Human Factors Problems Experienced by the Colorblind—A Pilot Questionnaire Survey

Abstract

The scientific literature on defective color vision contains virtually no studies of the commonplace human factors problems experienced by the “color-blind.” The majority of relevant studies reported, have either been concerned with genetics or with color vision theories. The practical problems involved in human engineering products used by color deficient individuals become more significant, when it is considered that some surveys place the incidence of some form of defective color vision as high as 8 percent of world male population and 2 percent of the female.

A pilot questionnaire survey was undertaken to test a proposed methodology for learning about and cataloguing the human factors problems experienced by color deficient individuals in dealing with the natural and man-made worlds.
