Improving Color Discrimination for Color Vision Deficiency (CVD) with Temporal-Domain Modulation

Color Vision Deficiency (CVD) is often characterized by the inability to distinguish color due to a defective or missing cone in the eye. Although it is possible to modify the observed color to make it easier for users to distinguish, this can lead to color confusion with unaffected colors. To address this problem we investigate how flicker can assist distinguishing colors for CVD patients. In preliminary study, we evaluated the efficiency of color and brightness modulation with 4 participants with normal vision. Our findings suggests that while brightness modulation was ineffective, color modulation can help users distinguish between different colors.
