Title: RECOGNITION OF VDU (VISUAL DISPLAY UNIT) PRESENTED COLORS BY COLOR DEFECTIVE OBSERVERS
Abstract: In order to determine the degree to which color defective observers can effectively use nonredundant color-coded information on a visual display unit, a choice reaction time experiment was conducted. The effect of advance training, stimulus size, and simultaneous color contrast was explored. Although all groups of subjects, including normal trichromats, experienced difficulties in performing the experimental task, all color defective observers performed worse than those with normal color vision. Within the group of color defectives, anomalous trichromats performed significantly better than did dichromats. Among dichromats, deuteranopes had significantly better results than did protanopes. The performance of all subjects was negatively influenced by simultaneous color contrast (in particular, green-yellow and cyan-white). The differences among all groups were qualitative rather than quantitative, implying that conditions under which normal trichromats show optimal performance will be the same for color defectives.
